Abstract
The prevalence and incidence of young-onset type 2 diabetes is increasing globally, especially in low- and middle-income countries, and predominantly affects non-White ethnic and racial populations. Young-onset type 2 is heterogeneous in terms of the genetic and environmental contributions to its underlying pathophysiology, which poses challenges for glycemic management. Young at-risk individuals remain underrepresented in clinical trials, including diabetes prevention studies, and there is still an insufficient evidence base to inform practice for this age group. Improvements in diabetes care delivery have not reached young people who will progress to have disabling complications at an age when they are most productive. This review summarizes recent studies on the epidemiology of young-onset type 2 diabetes and its complications. We discuss the genetic and environmental risk factors that act in concert to promote glycemic dysregulation and early onset of type 2 diabetes. We provide perspectives on diabetes prevention and management, and propose strategies to address the unique medical and psychosocial issues associated with young-onset type 2 diabetes. The Precision Medicine to Redefine Insulin Secretion and Monogenic Diabetes Randomized Controlled Trial (PRISM-RCT) is the first large-scale clinical trial designed to evaluate the effect of a structured care model that integrates biogenetic markers with communication and information technology on attaining strict metabolic targets and improving clinical outcomes in individuals with young-onset type 2 diabetes. The results of this study will inform the scientific community about the impact of multifactorial intervention and precision care in young patients, for whom the legacy effect is particularly significant.

A pretrained transformer model for decoding individual glucose dynamics from continuous glucose monitoring data. Natl Sci Rev 2025; 12:nwaf039. [PMID: 40191259 PMCID: PMC11970253 DOI: 10.1093/nsr/nwaf039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2025] [Revised: 01/22/2025] [Accepted: 02/05/2025] [Indexed: 04/09/2025] Open
Abstract
Continuous glucose monitoring (CGM) technology has grown rapidly to track real-time blood glucose levels and trends with improved sensor accuracy. The ease of use and wide availability of CGM will facilitate safe and effective decision making for diabetes management. Here, we developed an attention-based deep learning model, CGMformer, pretrained on a well-controlled and diverse corpus of CGM data to represent individual's intrinsic metabolic state and enable clinical applications. During pretraining, CGMformer encodes glucose dynamics including glucose level, fluctuation, hyperglycemia, and hypoglycemia into latent space with self-supervised learning. It shows generalizability in imputing glucose value across five external datasets with different populations and metabolic states (MAE = 3.7 mg/dL). We then fine-tuned CGMformer towards a diverse panel of downstream tasks in the screening of diabetes and its complications using task-specific data, which demonstrated a consistently boosted predictive accuracy over direct fine-tuning on a single task (AUROC = 0.914 for type 2 diabetes (T2D) screening and 0.741 for complication screening). By learning an intrinsic representation of an individual's glucose dynamics, CGMformer classifies non-diabetic individuals into six clusters with elevated T2D risks, and identifies a specific cluster with lean body-shape but high risk of glucose metabolism disorders, which is overlooked by traditional glucose measurements. Furthermore, CGMformer achieves high accuracy in predicting an individual's postprandial glucose response with dietary modelling (Pearson correlation coefficient = 0.763) and helps personalized dietary recommendations. Overall, CGMformer pretrains a transformer neural network architecture to learn an intrinsic representation by borrowing information from a large amount of daily glucose profiles, and demonstrates predictive capabilities fine-tuned towards a broad range of downstream applications, holding promise for the early warning of T2D and recommendations for lifestyle modification in diabetes management.

Clinical effectiveness and cost-effectiveness of first-line early combination of dipeptidyl peptidase 4 inhibitors and metformin in patients with type 2 diabetes in Taiwan: A modelling study. Diabetes Obes Metab 2025; 27:2183-2192. [PMID: 39888103 DOI: 10.1111/dom.16215] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2024] [Revised: 01/06/2025] [Accepted: 01/13/2025] [Indexed: 02/01/2025]
Abstract
AIMS Early dipeptidyl peptidase-4 inhibitors and metformin (DPP4i-Met) combination has been shown to extend the time to treatment failure and provide better glycaemic control for newly diagnosed type 2 diabetes (T2D) patients; however, the long-term clinical and economic outcomes of early DPP4i-Met combination remain unknown. We seek to assess the comparative long-term clinical and cost-effectiveness of DPP4i-Met versus Met for treatment-naïve T2D patients with inadequately controlled HbA1c (i.e., ≥8.5%). METHODS The IQVIA CORE Diabetes Model was used to simulate the quality-adjusted life years (QALYs) and healthcare costs over a lifetime from Taiwan's National Health Insurance Administration's perspective, with both QALYs and costs discounted at 3% annually. Model inputs were taken from the analyses of Taiwanese or Asian populations. Primary outcomes included the number needed to treat (NNT) to prevent one case of a clinical event and the incremental cost-effectiveness ratios (ICERs). Costs are presented in 2023 US dollars. RESULTS Over 40 years of projection, Met-DPP4i-treated patients had fewer complications than those using Met alone (e.g., lowering the incidence of stroke by 2.21% [2.68, 1.74]). The NNT using DPP4i-Met versus Met alone to prevent one case of stroke, microalbuminuria, neuropathy and background retinopathy was 45, 135, 65 and 182, respectively. Such long-term benefits in reducing costly complications offset the higher treatment cost of DDP4i-Met versus Met ($5796 vs. $5484/person). As a result, using DPP4i-Met versus Met yielded 0.086 QALYs gained and savings of $489 for overall treatment-naïve T2D patients and 0.064 QALYs gained and savings of $714 for young-onset T2D patients. CONCLUSIONS Early DPP4i-Met provides long-term clinical and economic benefits compared to Met alone for newly diagnosed T2D patients, including those with young-onset T2D.

Diabetol Metab Syndr 2025; 17:103. [PMID: 40140909 PMCID: PMC11948681 DOI: 10.1186/s13098-025-01673-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/19/2024] [Accepted: 03/16/2025] [Indexed: 03/28/2025] Open
Abstract
BACKGROUND Type 2 diabetes mellitus (T2DM) is increasingly affecting people aged 15-34, posing a serious public health challenge due to its faster progression and higher complication risks. This study examines the global, regional, and national burden of early-onset T2DM from 1990 to 2021, emphasizing trends and disparities across different sociodemographic contexts. METHODS Using data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021, we analyzed incidence, prevalence, mortality, disability-adjusted life years (DALYs), years lived with disability (YLDs), and years of life lost (YLLs) in people aged 15-34. Stratifications included age, sex, and the Socio-Demographic Index (SDI). Joinpoint regression significant temporal shifts, and decomposition analysis attributed changes in T2DM burden to factors such as prevalence, population growth, aging, and case fatality rates. Inequality was assessed with the Slope Index of Inequality and Concentration Index. RESULTS From 1990 to 2021, early-onset T2DM incidence and prevalence rose significantly worldwide, especially in high-SDI regions. Although global mortality and DALYs appeared relatively stable, low-SDI regions showed worrisome increases. Rising T2DM prevalence was the principal driver of mortality and DALYs, notably in low- and middle-SDI regions. Inequality analyses indicated widening disparities, with higher incidence and prevalence in high-SDI countries and more severe outcomes in low-SDI countries. CONCLUSIONS The global burden of early-onset T2DM among youths is escalating, with significant disparities across different sociodemographic levels. The findings underscore the urgent need for targeted public health interventions. Future research should focus on the underlying factors driving these trends and explore strategies for effective prevention and management of early-onset T2DM.

Abstract
BACKGROUND The prevalence of early-onset type 2 diabetes (EOD) is rapidly increasing. This study intends to screen for early cardiovascular abnormalities in patients newly diagnosed with EOD and evaluate the cardiovascular risk across cluster phenotypes. METHOD A total of 400 patients ≤ 40 years old with newly diagnosed type 2 diabetes were enrolled from the START cohort (the Study of The newly diAgnosed eaRly onset diabeTes). Cluster classification was performed using the K-means method based on age, BMI, HbA1c, HOMA2-β, HOMA2-IR, and GAD antibodies. Echocardiography and carotid ultrasound were performed within 3 months of diabetes diagnosis. Carotid ultrasound abnormalities included intimal thickening and plaque formation, while echocardiography assessed changes in cardiac structure and systolic/diastolic function. Cluster-specific partitioned polygenic scores (pPS) were used to validate our findings from a genetic perspective. RESULT Carotid artery abnormalities were detected in 26.3% of patients, and echocardiography abnormalities were observed in 20.0%. Patients with severe insulin resistant diabetes (SIRD) had the highest incidence of carotid artery abnormality (40.0%). After adjusting for relevant risk factors, fasting C-peptide levels were significantly associated with a 1.247-fold increase in the risk of carotid artery abnormalities. Left atrial enlargement was more prevalent in the SIRD (16.7%) and mild obesity-related diabetes (MOD) (18.5%) classifications. A high proportion of patients with SIRD had abnormal left ventricular geometry (36.1%). Increases in BMI, fasting C-peptide level and HOMA2IR were accompanied by a further increase in left atrial enlargement risk by 1.136-, 1.781- and 1.687-fold respectively. The pPS for lipodystrophy was higher in the EOD group with plaque formation, and showed a significant linear correlation with the ratio of the left atrial anteroposterior diameter to body surface area (LAAP/BSA) (R = 0.344, p < 0.001). CONCLUSION Heart and carotid artery abnormalities are common in patients with early-onset T2DM at the time of diagnosis. Patients with obesity and insulin resistance are at higher risk for cardiovascular abnormalities. Cluster classification based on clinical characteristics enables more accurate identification of patients at increased risk of cardiovascular complications at an early stage.

Abstract
This study investigated the relationship between fibrinogen-to-albumin ratio (FAR) and glucose metabolic state in patients with coronary heart disease (CHD). A total of 52,062 patients were enrolled in this study. Patients were classified according to FAR tertiles (T1: FAR < 0.0073; T2: 0.0073 ≤ FAR ≤ 0.0886; T3: FAR ≥ 0.0887). Patients were also classified into the normal glucose regulation (NGR) and elevated blood glucose (EBG) groups. The relationship between FAR and EBG was analyzed using logistic regression, and the association was evaluated according to sex and age. Among the participants, 32,471 (62.4%) had EBG, which was positively associated with FAR (odds ratio [OR], 1.19; 95% confidence interval [CI] 1.15-1.23). The OR of the FAR for EBG in males was higher than that in females (1.25; 95% CI 1.18-1.33 vs 1.15; 95% CI 1.10-1.20). Moreover, the OR of FAR for EBG was greater in patients aged 60 or younger (OR: 1.25; 95% CI 1.18-1.33) than in the elderly patients (over 60 years of age) (OR: 1.15; 95% CI 1.10-1.20). The results indicated a significant relationship between FAR and EBG and this association was higher in males and middle-aged patients.

Abstract
This study aimed to understand the influencing factors of diabetes among the cardiovascular high-risk population aged 35-75 in Hainan Province, in order to provide a reference basis for the development of scientific prevention strategies and intervention measures. From January 2016 to February 2023, a random sample of 71,819 residents aged 35-75 in Hainan Province was screened, identifying 12,936 cardiovascular high-risk individuals. All 2,908 diabetic patients were chosen as cases, with a 1:1 age- and gender-matched control group selected from the high-risk pool. Data were organized in Excel and analyzed using SPSS 27.0 for t-tests, chi-square tests, and multi-factorial logistic regression to evaluate lifestyle, dietary habits, blood glucose, and medical history as influencing factors among the high-risk cardiovascular population. BMI (OR = 1.071, 95%CI: 1.053-1.090) and elevated systolic blood pressure (OR = 1.005, 95%CI: 1.002-1.009), a frequency of seafood consumption more than three times per month (OR = 8.098, 95%CI: 7.100-9.237), and an increased ratio of triglycerides to high-density lipoprotein (OR = 1.296, 95%CI: 1.208-1.390) were risk factors for diabetes; whereas high school and below educational level (OR = 0.798, 95%CI: 0.678-0.938), high school above educational level (OR = 0.660, 95%CI: 0.491-0.886), exercise frequency of four or more times per week (OR = 0.621, 95%CI: 0.538-0.716), consumption of fresh vegetables 1-3 times per week (OR = 0.425, 95%CI: 0.283-0.640), and consumption of fresh fruits four or more times per week (OR = 0.743, 95%CI: 0.639-0.865) were protective factors against diabetes. Increased BMI, blood pressure, triglyceride-to-HDL ratio, and frequent seafood consumption were diabetes risks for Hainan's high-risk cardiovascular population. Enhanced screening, follow-up, and promotion of healthy lifestyles, including diet and weight control, were needed to lower disease risks.

Association between Type 2 Diabetes onset age and risk of cardiovascular disease and mortality: Two cohort studies from United Kingdom and Hong Kong. DIABETES & METABOLISM 2025; 51:101607. [PMID: 39832675 DOI: 10.1016/j.diabet.2025.101607] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/17/2024] [Revised: 12/13/2024] [Accepted: 12/16/2024] [Indexed: 01/22/2025]
Abstract
OBJECTIVE This study aimed to evaluate the association between type 2 diabetes mellitus (T2DM) onset age and risk of cardiovascular disease (CVD) and mortality. METHOD Two retrospective cohort studies were conducted using the electronic health records from the United Kingdom (UK) and Hong Kong (HK) on adults without CVD. During 2008-2013, 128,918 and 185,646 patients with new-onset T2DM were assigned to the T2DM group, and 5,052,770 and 3,159,396 patients without T2DM were included as controls in the UK and HK cohort, respectively. Patients were stratified into six age groups. Multivariable Cox regression, adjusted for baseline characteristics and fine stratification weights, was used to estimate the hazard ratios (HRs) and 95 % confidence intervals (CIs) for each outcome. RESULTS New-onset T2DM was associated with increased CVD and mortality risk, but the risks decreased with age. Compared to those without T2DM in the same age groups, the HR (95 % CI) for CVD in the UK cohort was 3.22 (2.80, 3.71), 1.21 (1.15, 1.26), and 0.99 (0.93, 1.05) for T2DM individuals at ages 18-39, 60-69, and ≥ 80, respectively. Similarly, the HR (95 % CI) for mortality among new-onset T2DM patients was 2.41 (2.06, 2.83) for age 18-39, 1.40 (1.34, 1.46) for age 60-69, and 1.12 (1.08, 1.16) for age ≥ 80. Results from the HK cohort showed a similar pattern. CONCLUSION Young onset of T2DM is associated with a significant impact on cardiovascular health later in life. This highlights the importance of the prevention of DM in young adults.

Modifiable factors and 10-year and lifetime cardiovascular disease risk in adults with new-onset hypertension: insights from the Kailuan cohort. BMC Med 2025; 23:80. [PMID: 39934863 PMCID: PMC11816795 DOI: 10.1186/s12916-025-03923-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2024] [Accepted: 02/03/2025] [Indexed: 02/13/2025] Open
Abstract
BACKGROUND Preventing cardiovascular disease (CVD) in adults with hypertension is essential, but it remains uncertain whether optimizing modifiable factors can eliminate the excess CVD risk associated with new-onset hypertension. METHODS In this prospective cohort study, 29,597 adults with new-onset hypertension and no prior CVD (from 2006-2016 surveys) were each matched by age and sex to a normotensive control. Eight modifiable factors were assessed using the American Heart Association's Life's Essential 8 algorithm. We followed participants for incident CVD until December 2020, estimating 10-year and lifetime (age 25-95) CVD risks using the Fine-Gray competing risks model. RESULTS Over a median follow-up of 9.81 years, adults with new-onset hypertension had higher 10-year (8.97% vs. 6.31%) and lifetime CVD risks (45.55% vs. 34.98%) compared to normotensive controls. After adjusting for age, sex, and other unmodifiable factors, each additional favorable factor was associated with a stepwise reduction in CVD risk (P-trend < 0.05). Hypertensive participants with four or more favorable factors had a 17% lower 10-year CVD risk (HR 0.83; 95% CI 0.72-0.97) and a similar lifetime CVD risk (HR 0.90; 95% CI 0.78-1.05) compared to normotensive controls. Notably, the protective effect was weaker among those with early-onset (before age 45) hypertension than those with later-onset (age ≥ 60) hypertension (P-interaction < 0.05). CONCLUSIONS In adults with new-onset hypertension, maintaining four or more modifiable factors at favorable levels was associated with a CVD risk comparable to that of normotensive individuals. However, young hypertensive adults may require more aggressive interventions to mitigate CVD risk.

Abstract
AIM Rising prevalence of Type 2 Diabetes (T2D) among young Asians has emerged as a public health crisis that threatens the long-term health, economic stability, and productivity of nations across Asia (1). Early-onset T2D poses unique challenges, including higher rates of undiagnosed cases, more aggressive disease progression, an increased risk of chronic complications and higher mortality (2). Hyperglycemia during the reproductive age especially among the female population can potentially have transgenerational impact through epigenetic changes. METHODS A comprehensive search was conducted on PubMed with a combination of relevant keywords. A preliminary draft prepared after review of literature was electronically circulated among a panel of 64 experts from various parts of the region and representatives of the participating organizations - Diabetes India (www.diabetesindia.org.in) and the Diabetes Asia Study Group (DASG, www.da-sg.org). RESULTS This Ahmedabad Declaration outlines the scale of the problem, its root causes, and a comprehensive action plan for Asian populations. The objectives of this declaration include raising awareness, addressing systemic barriers, and advocating for evidence-based policies and interventions, limited to people with T2D. Through collaborative efforts, we aim to mitigate the growing burden of diabetes in young Asians and secure a healthier future.

A polygenic risk score derived from common variants of monogenic diabetes genes is associated with young-onset type 2 diabetes and cardiovascular-kidney complications. Diabetologia 2025; 68:367-381. [PMID: 39579208 PMCID: PMC11732898 DOI: 10.1007/s00125-024-06320-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/05/2024] [Accepted: 09/16/2024] [Indexed: 11/25/2024]
Abstract
AIMS/HYPOTHESIS Monogenic diabetes is caused by rare mutations in genes usually implicated in beta cell biology. Common variants of monogenic diabetes genes (MDG) may jointly influence the risk of young-onset type 2 diabetes (YOD, diagnosed before the age of 40 years) and cardiovascular and kidney events. METHODS Using whole-exome sequencing data, we constructed a weighted polygenic risk score (wPRS) consisting of 135 common variants (minor allele frequency >0.01) of 34 MDG based on r2>0.2 for linkage disequilibrium in a discovery case-control cohort of 453 adults with YOD (median [IQR] age 39.7 [34.9-46.9] years) and 405 without YOD (median [IQR] age 56.7 [50.3-61.0] years), followed by validation in an independent cross-sectional cohort with array-based genotyping for YOD and a prospective cohort of individuals with type 2 diabetes for cardiovascular and kidney events. RESULTS In the discovery cohort, the OR of the 135 common variants for YOD ranged from 1.00 to 2.61. In the validation cohort (920 YOD and 4910 non-YOD), top-10%-wPRS was associated with an OR of 1.42 (95% CI 1.03, 1.95, p=0.033) for YOD compared with bottom-10%-wPRS. In 2313 individuals with type 2 diabetes (median [IQR]: age 53.4 [45.4-61.7] years; disease duration 4.0 [1.0-9.0] years) observed for a median (IQR) of 17.5 (14.4-21.8) years, standardised wPRS was associated with increased HR for incident cardiovascular events (1.16 [95% CI 1.06, 1.27], p=0.001), kidney events (1.09 [95% CI 1.02, 1.16], p=0.013) and cardiovascular-kidney events (1.10 [95% CI 1.03, 1.16], p=0.003). Using the 'bottom-20%-wPRS plus baseline disease duration <5 years' group as referent, the 'top-20%-wPRS plus baseline disease duration 5 to <10 years' group had unadjusted and adjusted HR of 1.60 (95% CI 1.17, 2.19, p=0.003) and 1.62 (95% CI 1.16, 2.26, p=0.005), respectively, for cardiovascular-kidney events compared with 1.38 (95% CI 0.97, 1.98, p=0.075) and 1.06 (95% CI 0.72, 1.57, p=0.752) in the 'bottom-20%-wPRS plus baseline disease duration ≥10 years' group. CONCLUSIONS/INTERPRETATION Common variants of MDG increased risk for YOD and cardiovascular-kidney events.

Abstract
OBJECTIVE To investigate the association of diabetes duration with cardiovascular disease (CVD) risk and to examine the relationship between lipid levels and CVD risk over the duration. METHODS Using the Korean National Health Insurance Service Cohort database, we identified 2 359 243 subjects with type 2 diabetes aged ≥ 20 years in 2015 to 2016. Baseline lipid levels and diabetes duration were evaluated and followed up until December 2020 (mean follow-up, 3.9 years). Subjects were categorized according to diabetes duration (new-onset, < 5 years, 5-9 years, or ≥ 10 years). We analyzed the new-onset diabetes group with low-density lipoprotein cholesterol (LDL-C) < 70 mg/dL as the reference group. The hazard ratios (HRs) and 95% CIs of myocardial infarction (MI) and ischemic stroke (IS) were estimated using a Cox proportional hazards model adjusted for potential confounders. RESULTS During follow-up, 45 883 cases of MI and 53 538 cases of IS were identified. The risk of MI or IS began to increase at LDL-C ≥ 160 mg/dL in the new-onset diabetes group, and at LDL-C ≥ 130 mg/dL in the group with diabetes duration < 5 years. Among subjects with diabetes duration of 5 to 9 years, LDL-C levels of 100-129 mg/dL, 130-159 mg/dL, and ≥ 160 mg/dL were significantly associated with the risk of MI (HR [95% CI] 1.13 [1.04-1.22], 1.28 [1.17-1.39], and 1.58 [1.42-1.76], respectively). MI risk in the diabetes duration ≥ 10 years group was increased by 16%, even in the LDL-C 70-99 mg/dL population (HR [95% CI] 1.16 [1.08-1.25]). CONCLUSION This population-based longitudinal study revealed that the LDL-C cutoff level for increasing the risk of CVD varied with diabetes duration and that the target LDL-C level should depend on the duration.

Abstract
AIM To investigate the relationship between age at diagnosis of type 2 diabetes and the risk of macrovascular disease, heart failure, and microvascular disease. METHODS In August 2022, PubMed/EMBASE were searched for articles reporting (i) coronary artery disease, cerebrovascular disease, peripheral vascular disease, amputation; (ii) heart failure; and (iii) retinopathy, neuropathy, nephropathy (albuminuria, chronic kidney disease [CKD], end-stage renal disease) by age at diagnosis of type 2 diabetes. Random effects, non-linear dose-response meta-analysis was undertaken for each outcome to assess the association with age at diagnosis (40 years = reference), using both crude and maximally adjusted odds ratios separately, with and without adjustment for current age (age at sampling). RESULTS We identified 42 articles (230,003 to 3,465,590 participants; 1035 to 391,140 events). Age at diagnosis was positively associated with the risk of macrovascular diseases, heart failure, and CKD, independent of current age, and negatively associated with retinopathy. For other microvascular outcomes, when adjusting for current age, a "reverse U" relationship was observed (peak risk = 55-60 years). DISCUSSION Retinopathy was negatively associated with age at diagnosis, highlighting the importance of retinopathy screening in early-onset type 2 diabetes. The implications of other associations were unclear due to the heterogeneity in methodologies and findings.

Young-onset type 2 diabetes mellitus enhances proteinuria, but not glomerular filtration rate decline: A Japanese cohort study. J Diabetes Investig 2024; 15:1444-1456. [PMID: 39058327 PMCID: PMC11442850 DOI: 10.1111/jdi.14272] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/17/2024] [Revised: 07/07/2024] [Accepted: 07/11/2024] [Indexed: 07/28/2024] Open
Abstract
AIMS/INTRODUCTION The time course of chronic kidney disease in young-onset type 2 diabetes mellitus remains unclear. We compared the trajectories of proteinuria and estimated glomerular filtration rate (eGFR) decline between young-onset (aged ≤40 years) and late-onset (aged >40 years) type 2 diabetes mellitus in a Japanese multicenter cohort. MATERIALS AND METHODS Participants without diabetic kidney disease were divided into two groups according to age at diagnosis: young- and late-onset. The primary endpoint was eGFR <60 mL/min/1.73 m2, proteinuria or both. Multivariable Cox proportional hazards were calculated to estimate incidence. RESULTS Among 626 participants with type 2 diabetes mellitus, 78 (12.4%) had young-onset and 548 (87.6%) had late-onset diabetes. The incidence of eGFR <60 mL/min/1.73 m2 was lower (16.7% vs 33.5%, P = 0.003), but that of proteinuria was higher (46.2% vs 28.9%, P = 0.002) in the young-onset type 2 diabetes mellitus group. The Kaplan-Meyer curve showed that young-onset type 2 diabetes mellitus was associated with a decreased hazard ratio (HR) for eGFR <60 mL/min/1.73 m2 and an increased HR for proteinuria compared with late-onset type 2 diabetes mellitus. In the multivariate Cox analysis, young-onset type 2 diabetes mellitus increased the HR (95% confidence interval) of proteinuria (1.53, 95% confidence interval 1.03-2.26), but did not change the eGFR <60 mL/min/1.73 m2 HR. CONCLUSIONS Young-onset type 2 diabetes mellitus has a lower HR of eGFR <60 mL/min/1.73 m2 and an increased HR of proteinuria compared with late-onset type 2 diabetes mellitus, indicating that young-onset type 2 diabetes mellitus has a different time course for the development of proteinuria and subsequent eGFR decline.

Abstract
AIMS It is unclear whether type 2 diabetes diagnosed in young adulthood is associated with increased severity than that occurring later in life beyond longer lifetime exposure to hyperglycemia. This study aimed at assessing the independent association of age at type 2 diabetes diagnosis with all-cause mortality. METHODS This prospective cohort study enrolled 15,773 Caucasian patients with type 2 diabetes in 19 Italian centers in 2006-2008. Cardiometabolic risk profile and presence of complications and comorbidities were assessed at baseline and participants were stratified by quartiles of age at diabetes diagnosis. All-cause mortality was verified on 31 October 2015. RESULTS Valid information on vital status was retrieved for 15,656 participants (99.3%). Patients in the lowest quartile had the longest diabetes duration, the worst glycemic control and the highest prevalence of insulin treatment, obesity, atherogenic dyslipidemia, and smoking habits. All complications were inversely associated with age at diabetes diagnosis after adjustment for age and sex, but not after further adjustment for diabetes duration. Percentages of death, Kaplan-Meier estimates, and unadjusted hazard ratios and mortality rates increased from the lowest to the highest quartile. In contrast, when adjusting for age and sex, participants falling in the lowest quartile, showed the highest mortality risk [hazard ratio 1.321 (95% confidence interval 1.196-1.460), P < 0.0001]. However, differences among quartiles disappeared after adjustment for diabetes duration, complications/comorbidities, or other cardiovascular risk factors. CONCLUSIONS Type 2 diabetes onset in young adulthood is associated with increased mortality that is mainly driven by longer diabetes duration favoring the development of complications. TRIAL REGISTRATION ClinicalTrials.gov, NCT00715481, retrospectively registered 15 July, 2008.

Abstract
AIMS To examine the impact of current age, age at diagnosis, and duration of diabetes on the incidence rate of complications among people with type 2 diabetes. METHODS Baseline data from 19,327 individuals with type 2 diabetes in the UK Biobank were analysed. Poisson regression was used to model incidence rates by current age, age at diagnosis, and duration of diabetes for the following outcomes: myocardial infarction (MI), heart failure (HF), stroke, end-stage kidney diseases (ESKD), chronic kidney diseases (CKD), liver diseases, depression, and anxiety. RESULTS The mean age at baseline was 60.2 years, and median follow-up was 13.9 years. Diabetes duration was significantly longer among those with younger-onset type 2 diabetes (diagnosed at <40 years) compared to later-onset type 2 diabetes (diagnosed at ≥40 years), 16.2 and 5.3 years, respectively. Incidence rates of MI, HF, stroke, and CKD had strong positive associations with age and duration of diabetes, whereas incidence rates of ESKD liver diseases, and anxiety mainly depended on duration of diabetes. The incidence rates of depression showed minor variation by age and duration of diabetes and were highest among those diagnosed at earlier ages. No clear evidence of an effect of age of onset of diabetes on risk of complications was apparent after accounting for current age and duration of diabetes. CONCLUSIONS Our study indicates age at diagnosis of diabetes does not significantly impact the incidence of complications, independently of the duration of diabetes. Instead, complications are primarily influenced by current age and diabetes duration.

Abstract
The key aim of diabetes management is to prevent complications, which are a major cause of morbidity and mortality. At an individual level, people with diabetes are less likely than they were several decades ago to experience classical macrovascular and microvascular complications as a result of improvements in modifiable cardiovascular risk factors and preventive healthcare. However, a significant burden of diabetes complications persists at a population level because of the increasing incidence of diabetes, as well as longer lifetime exposure to diabetes because of younger diagnosis and increased life expectancy. Trials have shown that the most effective strategy for preventing complications of diabetes is a multifactorial approach focussing simultaneously on the management of diet, exercise, glucose levels, blood pressure and lipids. In addition to the cornerstone strategies of addressing diet, exercise and lifestyle measures, the introduction of newer glucose-lowering agents, including sodium-glucose transport protein 2 inhibitors and glucagon-like peptide-1 agonists, have brought about a paradigm shift in preventing the onset and progression of complications of type 2 diabetes, particularly cardiovascular and renal disease. The improvement in rates of classical complications of diabetes over time has been accompanied by a growing awareness of non-traditional complications, including non-alcoholic fatty liver disease. These emerging complications may not respond to a glycaemic-centred approach alone and highlight the importance of foundational strategies centred on lifestyle measures and supported by pharmaceutical therapy to achieve weight loss and reduce metabolic risk in patients living with diabetes.

Abstract
INTRODUCTION We designed and implemented a patient-centered, data-driven, holistic care model with evaluation of its impacts on clinical outcomes in patients with young-onset type 2 diabetes (T2D) for which there is a lack of evidence-based practice guidelines. RESEARCH DESIGN AND METHODS In this 3-year Precision Medicine to Redefine Insulin Secretion and Monogenic Diabetes-Randomized Controlled Trial, we evaluate the effects of a multicomponent care model integrating use of information and communication technology (Joint Asia Diabetes Evaluation (JADE) platform), biogenetic markers and patient-reported outcome measures in patients with T2D diagnosed at ≤40 years of age and aged ≤50 years. The JADE-PRISM group received 1 year of specialist-led team-based management using treatment algorithms guided by biogenetic markers (genome-wide single-nucleotide polymorphism arrays, exome-sequencing of 34 monogenic diabetes genes, C-peptide, autoantibodies) to achieve multiple treatment goals (glycated hemoglobin (HbA1c) <6.2%, blood pressure <120/75 mm Hg, low-density lipoprotein-cholesterol <1.2 mmol/L, waist circumference <80 cm (women) or <85 cm (men)) in a diabetes center setting versus usual care (JADE-only). The primary outcome is incidence of all diabetes-related complications. RESULTS In 2020-2021, 884 patients (56.6% men, median (IQR) diabetes duration: 7 (3-12) years, current/ex-smokers: 32.5%, body mass index: 28.40±5.77 kg/m2, HbA1c: 7.52%±1.66%, insulin-treated: 27.7%) were assigned to JADE-only (n=443) or JADE-PRISM group (n=441). The profiles of the whole group included positive family history (74.7%), general obesity (51.4%), central obesity (79.2%), hypertension (66.7%), dyslipidemia (76.4%), albuminuria (35.4%), estimated glomerular filtration rate <60 mL/min/1.73 m2 (4.0%), retinopathy (13.8%), atherosclerotic cardiovascular disease (5.2%), cancer (3.1%), emotional distress (26%-38%) and suboptimal adherence (54%) with 5-item EuroQol for Quality of Life index of 0.88 (0.87-0.96). Overall, 13.7% attained ≥3 metabolic targets defined in secondary outcomes. In the JADE-PRISM group, 4.5% had pathogenic/likely pathogenic variants of monogenic diabetes genes; 5% had autoantibodies and 8.4% had fasting C-peptide <0.2 nmol/L. Other significant events included low/large birth weight (33.4%), childhood obesity (50.7%), mental illness (10.3%) and previous suicide attempts (3.6%). Among the women, 17.3% had polycystic ovary syndrome, 44.8% required insulin treatment during pregnancy and 17.3% experienced adverse pregnancy outcomes. CONCLUSIONS Young-onset diabetes is characterized by complex etiologies with comorbidities including mental illness and lifecourse events. TRIAL REGISTRATION NUMBER NCT04049149.

Abstract
Over the past 20 years, the incidence and prevalence of type 2 diabetes mellitus (T2DM) in children and adolescents have increased, particularly in racial and ethnic minorities. Despite the rise in T2DM in children and adolescents, the pathophysiology and progression of disease in this population are not clearly understood. Youth-onset T2DM has a more adverse clinical course than is seen in those who develop T2DM in adulthood or those with T1DM. Furthermore, the available therapeutic options are more limited for children and adolescents with T2DM compared to adult patients, mostly due to the challenges of implementing clinical trials. A better understanding of the mechanisms underlying the de-velopment and aggressive disease phenotype of T2DM in youth is important to finding effective prevention and management strategies. This review highlights the key evidence about T2DM in children and adolescents and its current burden and challenges both in clinical care and research activities.

Abstract
Precision diagnosis is the keystone of clinical medicine. In East Asians, classical type 1 diabetes is uncommon in patients with youngonset diabetes diagnosed before age of 40, in whom a family history, obesity, and beta-cell and kidney dysfunction are key features. Young-onset diabetes affects one in five Asian adults with diabetes in clinic settings; however, it is often misclassified, resulting in delayed or non-targeted treatment. Complex aetiologies, long disease duration, aggressive clinical course, and a lack of evidence-based guidelines have contributed to variable care standards and premature death in these young patients. The high burden of comorbidities, notably mental illness, highlights the numerous knowledge gaps related to this silent killer. The majority of adult patients with youngonset diabetes are managed as part of a heterogeneous population of patients with various ages of diagnosis. A multidisciplinary care team led by physicians with special interest in young-onset diabetes will help improve the precision of diagnosis and address their physical, mental, and behavioral health. To this end, payors, planners, and providers need to align and re-design the practice environment to gather data systematically during routine practice to elucidate the multicausality of young-onset diabetes, treat to multiple targets, and improve outcomes in these vulnerable individuals.

Abstract
The incidence rates of type 2 diabetes among adults in Asia have been stable, but the rates in youth and young adults have increased. In territory-wide surveillance in Hong Kong, Special Administrative Region of People's Republic of China, all-cause mortality rates among people with diabetes have exhibited a declining trend in the past 15 years, with a narrowing in the mortality gap between people with and without diabetes. At the same time, the improvement in survival resulted in a changing age structure and disease profile of people with diabetes, towards an increasing proportion of older people with long diabetes duration and multi-morbidities. Reductions in event rates were not observed in the youngest age group who also had the least gains in risk factor control and uptake in organ protective drugs over time. A young age at diabetes diagnosis, associated with exposure to high glycemic burden from an early age, predicted higher risks of complications and premature mortality compared with later-onset of diabetes. People presenting with type 2 diabetes below 40 years of age were 5-fold more likely to die and their life expectancy was shortened by 8 years than age-matched counterparts without diabetes. Analysis of population-based data in Hong Kong Chinese identified hypertension followed by chronic kidney disease as the leading contributor to mortality in young people, indicating that efforts to optimize non-glycemic risk factors and organ protection are as important in young individuals as it is in the older population.

World J Diabetes 2024; 15:240-250. [PMID: 38464373 PMCID: PMC10921163 DOI: 10.4239/wjd.v15.i2.240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/20/2023] [Accepted: 01/22/2024] [Indexed: 02/04/2024] Open
Abstract
BACKGROUND Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide, the global burden of which is rising. It is still unclear the extent to which prediabetes contributes to the risk of CVD in various age brackets among adults. To develop a focused screening plan and treatment for Chinese adults with prediabetes, it is crucial to identify variations in the connection between prediabetes and the risk of CVD based on age. AIM To examine the clinical features of prediabetes and identify risk factors for CVD in different age groups in China. METHODS The cross-sectional study involved a total of 46239 participants from June 2007 through May 2008. A thorough evaluation was conducted. Individuals with prediabetes were categorized into two groups based on age. Chinese atherosclerotic CVD risk prediction model was employed to evaluate the risk of developing CVD over 10 years. Random forest was established in both age groups. SHapley Additive exPlanation method prioritized the importance of features from the perspective of assessment contribution. RESULTS In total, 6948 people were diagnosed with prediabetes in this study. In pre-diabetes, prevalences of CVD were 5 (0.29%) in the younger group and 148 (2.85%) in the older group. Overall, 11.11% of the younger group and 29.59% of the older group were intermediate/high-risk of CVD for prediabetes without CVD based on the Prediction for ASCVD Risk in China equation in ten years. In the younger age group, the 10-year risk of CVD was found to be more closely linked to family history of CVD rather than lifestyle, whereas in the older age group, resident status was more closely linked. CONCLUSION The susceptibility to CVD is age-specific in newly diagnosed prediabetes. It is necessary to develop targeted approaches for the prevention and management of CVD in adults across various age brackets.

Abstract
BACKGROUND This study investigated the effects of early-onset type 2 diabetes (EOD) vs late-onset type 2 diabetes (LOD) on nonfatal cardiovascular diseases (CVD) in China. METHODS We conducted a cross-sectional survey of 46 239 participants from 14 provinces in China from 2007 to 2008, selecting 4949 participants with type 2 diabetes for analysis. Participants were categorized as EOD (<40 years) or LOD (≥40 years) based on age at diabetes diagnosis. Sociodemographic and nonfatal CVD information was collected through an interviewer-assisted questionnaire and clinical examination. Logistic regression analysis was used to investigate the nonfatal CVD risk. RESULTS Out of 4949 participants with type 2 diabetes, 390 (7.88%) had nonfatal CVD. Participants with EOD had a higher age-standardized prevalence of nonfatal CVD than those with LOD (11.4% vs 4.4%). Compared to LOD patients, EOD patients tended to be males and had a higher family history of diabetes, unhealthy lifestyle behaviors, and lower blood pressure levels. After adjustment for age and sex, EOD patients had a higher risk of nonfatal CVD than LOD patients (odds ratio [OR] 2.3, 95% CI 1.5-3.5). After further adjustment for diabetes duration, use of drugs, and other risk factors, the OR of nonfatal CVD was reduced but significant (OR 1.8, 95% CI 1.1-2.9). Sensitivity analysis revealed that EOD patients with metabolic syndrome had an increased nonfatal CVD risk compared to LOD patients (OR 2.0, 95% CI 1.2-3.5). CONCLUSIONS EOD patients are at increased risk of nonfatal CVD. Individualized intervention and management measures for EOD patients are necessary.

Abstract
BACKGROUND Precision medicine has the potential to improve cardiovascular disease (CVD) risk prediction in individuals with Type 2 diabetes (T2D). METHODS We conducted a systematic review and meta-analysis of longitudinal studies to identify potentially novel prognostic factors that may improve CVD risk prediction in T2D. Out of 9380 studies identified, 416 studies met inclusion criteria. Outcomes were reported for 321 biomarker studies, 48 genetic marker studies, and 47 risk score/model studies. RESULTS Out of all evaluated biomarkers, only 13 showed improvement in prediction performance. Results of pooled meta-analyses, non-pooled analyses, and assessments of improvement in prediction performance and risk of bias, yielded the highest predictive utility for N-terminal pro b-type natriuretic peptide (NT-proBNP) (high-evidence), troponin-T (TnT) (moderate-evidence), triglyceride-glucose (TyG) index (moderate-evidence), Genetic Risk Score for Coronary Heart Disease (GRS-CHD) (moderate-evidence); moderate predictive utility for coronary computed tomography angiography (low-evidence), single-photon emission computed tomography (low-evidence), pulse wave velocity (moderate-evidence); and low predictive utility for C-reactive protein (moderate-evidence), coronary artery calcium score (low-evidence), galectin-3 (low-evidence), troponin-I (low-evidence), carotid plaque (low-evidence), and growth differentiation factor-15 (low-evidence). Risk scores showed modest discrimination, with lower performance in populations different from the original development cohort. CONCLUSIONS Despite high interest in this topic, very few studies conducted rigorous analyses to demonstrate incremental predictive utility beyond established CVD risk factors for T2D. The most promising markers identified were NT-proBNP, TnT, TyG and GRS-CHD, with the highest strength of evidence for NT-proBNP. Further research is needed to determine their clinical utility in risk stratification and management of CVD in T2D.

Abstract
BACKGROUND High cardiovascular mortality has been reported in young patients with diabetes. However, the underlying pathology in different age groups of patients with diabetes has not been studied. METHODS AND RESULTS The aim of this study was to investigate the plaque characteristics and underlying pathology of acute coronary syndrome in different age groups of patients with or without diabetes in a large cohort. Patients who presented with acute coronary syndrome and underwent preintervention optical coherence tomography imaging were included. Culprit plaque was classified as plaque rupture, plaque erosion, or calcified plaque and stratified into 5 age groups. Plaque characteristics including features of vulnerability were examined by optical coherence tomography. Among 1394 patients, 482 (34.6%) had diabetes. Patients with diabetes, compared with patients without diabetes, had a higher prevalence of lipid-rich plaque (71.2% versus 64.8%, P=0.016), macrophage (72.0% versus 62.6%, P<0.001), and cholesterol crystal (27.6% versus 19.7%, P<0.001). Both diabetes and nondiabetes groups showed a decreasing trend in plaque erosion with age (patients with diabetes, P=0.020; patients without diabetes, P<0.001). Patients without diabetes showed an increasing trend with age in plaque rupture (P=0.004) and lipid-rich plaque (P=0.018), whereas patients with diabetes had a high prevalence of these vulnerable features at an early age that remained high across age groups. CONCLUSIONS Patients without diabetes showed an increasing trend with age in plaque rupture and lipid-rich plaque, whereas patients with diabetes had a high prevalence of these vulnerable features at an early age. These results suggest that atherosclerotic vascular changes with increased vulnerability start at a younger age in patients with diabetes.

Abstract
OBJECTIVE To examine the associations between age at type 2 diabetes diagnosis and the relative and absolute risk of all-cause and cause-specific mortality in England. RESEARCH DESIGN AND METHODS In this cohort study using primary care data from the Clinical Practice Research Datalink, we identified 108,061 individuals with newly diagnosed type 2 diabetes (16-50 years of age), matched to 829,946 individuals without type 2 diabetes. We estimated all-cause and cause-specific mortality (cancer, cardiorenal, other [noncancer or cardiorenal]) by age at diagnosis, using competing-risk survival analyses adjusted for key confounders. RESULTS Comparing individuals with versus without type 2 diabetes, the relative risk of death decreased with an older age at diagnosis: the hazard ratio for all-cause mortality was 4.32 (95% CI 3.35-5.58) in individuals diagnosed at ages 16-27 years compared with 1.53 (95% CI 1.46-1.60) at ages 48-50 years. Smaller relative risks by increasing age at diagnosis were also observed for cancer, cardiorenal, and noncancer or cardiorenal death. Irrespective of age at diagnosis, the 10-year absolute risk of all-cause and cause-specific mortality were higher in individuals with type 2 diabetes; yet, the absolute differences were small. CONCLUSIONS Although the relative risk of death in individuals with versus without type 2 was higher at younger ages, the 10-year absolute risk of all investigated causes of death was small and similar in the two groups. Further multidecade studies could help estimate the long-term risk of complications and death in individuals with early-onset type 2 diabetes.

Abstract
Type 2 diabetes diagnosed in childhood or early adulthood is termed early-onset type 2 diabetes. Cases of early-onset type 2 diabetes are increasing rapidly globally, alongside rising obesity. Compared with a diagnosis later in life, an earlier-onset diagnosis carries an unexplained excess risk of microvascular complications, adverse cardiovascular outcomes, and earlier death. Women with early-onset type 2 diabetes also have a higher risk of adverse pregnancy outcomes. The high burden of complications renders individuals with early-onset type 2 diabetes at future risk of multimorbidity and interventions to reverse these concerning trends should be a priority. Within the early-onset cohort, disease pathophysiology and interventions have been better studied in paediatric-onset (<19 years) type 2 diabetes compared to adults; however, young adults aged 19-39 years (a larger number proportionally) are not well characterised and are also invisible in the current evidence base supporting management, which is derived from trials in later-onset type 2 diabetes. Young adults with type 2 diabetes face challenges in self-management that older individuals are less likely to experience (being in education or of working age, higher diabetes distress, and possible obesity-related stigma and diabetes-related stigma). There is a major research gap as to the optimal strategies to deploy in managing type 2 diabetes in adolescents and young adults, given that current models of care appear to not work as well in this age group. In the face of manifold risk factors (obesity, female sex, social deprivation, non-White European ethnicity, and genetic risk factors) prevention strategies with tailored lifestyle interventions, where needed, are likely to have greater success, but more evidence is needed. In this Review, we draw on evidence from both adolescents and young adults to provide a contemporary update on the current insights and emerging trends in early-onset type 2 diabetes.

Cardiovasc Diabetol 2023; 22:241. [PMID: 37667316 PMCID: PMC10476404 DOI: 10.1186/s12933-023-01951-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Accepted: 08/07/2023] [Indexed: 09/06/2023] Open
Abstract
BACKGROUND We examined ethnic differences in the association between age at diagnosis of diabetes and the risk of cardiovascular complications. METHODS We conducted a population-based cohort study in Ontario, Canada among individuals with diabetes and matched individuals without diabetes (2002-18). We fit Cox proportional hazards models to determine the associations of age at diagnosis and ethnicity (Chinese, South Asian, general population) with cardiovascular complications. We tested for an interaction between age at diagnosis and ethnicity. RESULTS There were 453,433 individuals with diabetes (49.7% women) and 453,433 matches. There was a significant interaction between age at diagnosis and ethnicity (P < 0.0001). Young-onset diabetes (age at diagnosis < 40) was associated with higher cardiovascular risk [hazard ratios: Chinese 4.25 (3.05-5.91), South Asian: 3.82 (3.19-4.57), General: 3.46 (3.26-3.66)] than usual-onset diabetes [age at diagnosis ≥ 40 years; Chinese: 2.22 (2.04-2.66), South Asian: 2.43 (2.22-2.66), General: 1.83 (1.81-1.86)] versus ethnicity-matched individuals. Among those with young-onset diabetes, Chinese ethnicity was associated with lower overall cardiovascular [0.44 (0.32-0.61)] but similar stroke risks versus the general population; while South Asian ethnicity was associated with lower overall cardiovascular [0.75 (0.64-0.89)] but similar coronary artery disease risks versus the general population. In usual-onset diabetes, Chinese ethnicity was associated with lower cardiovascular risk [0.44 (0.42-0.46)], while South Asian ethnicity was associated with lower cardiovascular [0.90 (0.86-0.95)] and higher coronary artery disease [1.08 (1.01-1.15)] risks versus the general population. CONCLUSIONS There are important ethnic differences in the association between age at diagnosis and risk of cardiovascular complications.

Abstract
Background Precision medicine has the potential to improve cardiovascular disease (CVD) risk prediction in individuals with type 2 diabetes (T2D). Methods We conducted a systematic review and meta-analysis of longitudinal studies to identify potentially novel prognostic factors that may improve CVD risk prediction in T2D. Out of 9380 studies identified, 416 studies met inclusion criteria. Outcomes were reported for 321 biomarker studies, 48 genetic marker studies, and 47 risk score/model studies. Results Out of all evaluated biomarkers, only 13 showed improvement in prediction performance. Results of pooled meta-analyses, non-pooled analyses, and assessments of improvement in prediction performance and risk of bias, yielded the highest predictive utility for N-terminal pro b-type natriuretic peptide (NT-proBNP) (high-evidence), troponin-T (TnT) (moderate-evidence), triglyceride-glucose (TyG) index (moderate-evidence), Genetic Risk Score for Coronary Heart Disease (GRS-CHD) (moderate-evidence); moderate predictive utility for coronary computed tomography angiography (low-evidence), single-photon emission computed tomography (low-evidence), pulse wave velocity (moderate-evidence); and low predictive utility for C-reactive protein (moderate-evidence), coronary artery calcium score (low-evidence), galectin-3 (low-evidence), troponin-I (low-evidence), carotid plaque (low-evidence), and growth differentiation factor-15 (low-evidence). Risk scores showed modest discrimination, with lower performance in populations different from the original development cohort. Conclusions Despite high interest in this topic, very few studies conducted rigorous analyses to demonstrate incremental predictive utility beyond established CVD risk factors for T2D. The most promising markers identified were NT-proBNP, TnT, TyG and GRS-CHD, with the highest strength of evidence for NT-proBNP. Further research is needed to determine their clinical utility in risk stratification and management of CVD in T2D.

Abstract
We investigated the risk of developing chronic kidney disease (CKD) in patients with young-onset Type 2 diabetes (YOD, diagnosed age < 40 years). We enrolled 84,384 patients aged 20-64 who started anti-diabetic medication between 2010 and 2011 from the Korea National Health Insurance Sharing Service; patients with Type 1 diabetes or a history of CKD were excluded. Multivariate logistic regression analyses were performed to adjust for YOD-distinct variables and compare the incidence of CKD between YOD and late-onset diabetes (LOD, diagnosed age ≥ 40 years). During the median observation period of 5.16 years (interquartile range: 4.58-5.77 years), 1480 out of 77,039 LOD patients and 34 out of 7345 YOD patients developed CKD. Patients with YOD had distinct baseline characteristics compared with the patients with LOD. The odds ratio of developing CKD in patients with YOD over LOD was 1.70 (95% CI 1.15-2.51) after adjusting clinically distinct variables. The increased CKD odds in YOD compared with LOD was greater in the non-smoking group (OR 2.03, 95% CI 1.26-3.26) than in the smoking group (OR 1.49, 95% CI 0.74-2.98, p = 0.0393 for interaction). Among YOD patients, hypertension (34.76% vs. 64.71%, p = 0.0003), dyslipidemia (46.87% vs. 73.53%, p = 0.0019), and sulfonylurea use (35.54% vs. 52.94%, p = 0.0345) were associated with CKD development. YOD patients have a greater risk of developing CKD than LOD patients after adjusting clinically distinct variables.

Abstract
AIM To ascertain the risk of progression to diabetes among Chinese women with PCOS. METHODS Women with PCOS (n = 3978) were identified from the Hong Kong Diabetes Surveillance Database based on the ICD-9 code for PCOS diagnosis and women without PCOS served as controls (n = 39780), matched 1:10 by age. RESULT(S) The mean follow-up was 6.28 ± 4.20 and 6.95 ± 4.33 years in women with PCOS and controls, respectively. The crude incidence rate of diabetes was 14.25/1000 person-years in women with PCOS compared with 3.45 in controls. The crude hazard ratio of diabetes in women with PCOS was 4.23 (95 % CI: 3.73-4.80, p < 0.001). Further stratified by age group, the risk of developing diabetes decreased with increasing age but it remained significantly higher in women with PCOS across all age groups. It also suggested that the incidence rate of diabetes in women with PCOS aged 20-29 is highly comparable to that in healthy women aged ≥ 40. More than half of the incident diabetes captured during the follow-up in women with PCOS cohort were young-onset diabetes. CONCLUSION Women diagnosed with PCOS at a younger age have the highest relative risk of developing diabetes, suggesting frequent glycemic status screening is required to detect diabetes at an early stage.

Abstract
Diabetic nephropathy (DN) is a polygenic disorder with few risk variants showing robust replication in large-scale genome-wide association studies. To understand the role of DNA methylation, it is important to have the prevailing genomic view to distinguish key sequence elements that influence gene expression. This is particularly challenging for DN because genome-wide methylation patterns are poorly defined. While methylation is known to alter gene expression, the importance of this causal relationship is obscured by array-based technologies since coverage outside promoter regions is low. To overcome these challenges, we performed methylation sequencing using leukocytes derived from participants of the Finnish Diabetic Nephropathy (FinnDiane) type 1 diabetes (T1D) study (n = 39) that was subsequently replicated in a larger validation cohort (n = 296). Gene body-related regions made up more than 60% of the methylation differences and emphasized the importance of methylation sequencing. We observed differentially methylated genes associated with DN in 3 independent T1D registries originating from Denmark (n = 445), Hong Kong (n = 107), and Thailand (n = 130). Reduced DNA methylation at CTCF and Pol2B sites was tightly connected with DN pathways that include insulin signaling, lipid metabolism, and fibrosis. To define the pathophysiological significance of these population findings, methylation indices were assessed in human renal cells such as podocytes and proximal convoluted tubule cells. The expression of core genes was associated with reduced methylation, elevated CTCF and Pol2B binding, and the activation of insulin-signaling phosphoproteins in hyperglycemic cells. These experimental observations also closely parallel methylation-mediated regulation in human macrophages and vascular endothelial cells.

Predictors of total mortality and their differential association on premature or late mortality in the SUN cohort. Exp Gerontol 2023; 172:112048. [PMID: 36521566 DOI: 10.1016/j.exger.2022.112048] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Revised: 12/02/2022] [Accepted: 12/06/2022] [Indexed: 12/14/2022]
Abstract
Several studies have tried to analyse the association between all-cause mortality and different risk factors, (especially those which are modifiable, such as smoking, diet or exercise), to develop public health preventive strategies. However, a specific analysis of predictors of premature and late mortality is needed to give more precise recommendations. Considering that there are risk factors which exert an influence on some diseases and not on others, we expect that, similarly, they may have a different impact depending on the timing of mortality, separating premature (≤65 years) from late mortality (>65 years). Thus, we prospectively followed-up during a median of 12 years a cohort of 20,272 university graduates comprising an ample range of ages at inception. Time-dependent, covariate-adjusted Cox models were used to estimate adjusted hazard ratios (HR) and their 95 % confidence intervals (CI) for each predictor. The strongest independent predictor of mortality at any age was physical activity which was associated with reduced risk of total, premature and late mortality (range of HRs when comparing the highest vs. the lowest level: 0.24 to 0.48). Specific strong predictors for premature mortality were smoking, HR: 4.22 (95 % CI: 2.42-7.38), and the concurrence of ≥2 metabolic conditions at baseline, HR: 1.97 (1.10-3.51). The habit of sleeping a long nap (≥30 min/d), with HR: 2.53 (1.30-4.91), and poor adherence to the Mediterranean Diet (≤3 points in a 0 to 8 score vs. ≥6 points), with HR: 2.27 (1.08-4.76), were the strongest specific predictors for late mortality. Smoking, diet quality or lifestyles, probably should be differentially assessed as specific predictors for early and late mortality. In the era of precision medicine, this approach will allow tailored recommendations appropriate to each person's age and baseline condition.

Abstract
Type 2 diabetes (T2DM), its related morbidities and entrenched diabetes-related inequities pose significant challenges for health care delivery systems in Aotearoa New Zealand (NZ). Primary care services undertake the majority of diabetes prevention work by initially detecting and managing those with prediabetes. In this viewpoint, we present available NZ data to highlight NZ trends in prediabetes and consider the current NZ clinical guidelines and the prediabetes care pathway. Multiple areas for improvement are identified to optimise diabetes prevention, potentially reduce T2DM inequities, and sustain more effective prediabetes management in primary care in NZ.

Abstract
BACKGROUND There is paucity of data examining healthcare costs among persons with comorbid diabetes and cardiorenal conditions. OBJECTIVE To elucidate the longitudinal trends and quantify the incremental healthcare costs associated with the following cardiorenal conditions: atherosclerotic cardiovascular disease (ASCVD), heart failure (HF), and kidney disease, among persons with diabetes. METHODS Medical Expenditure Panel Survey data (2008-2019) were used to identify adults with diabetes and comorbid cardiorenal conditions. Overall, medical and pharmaceutical costs were ascertained (in 2019 US dollars). Analyses were adjusted for 14 variables using a two-part regression model. RESULTS Among 32,519 adults with diabetes, the mean (standard error [SE]) annual healthcare costs were $13,829 ($213), with medical and prescription components contributing $9301 ($172) and $4528 ($98), respectively. Overall healthcare costs rose by 26.8% from $12,791 (2008-2009) to $16,215 (2018-2019) over the study period, driven by 42.5% and 20.3% increase in pharmaceutical and medical spending, respectively. Similar trends were observed for subgroup of persons with cardiorenal conditions. Compared to their counterparts without cardiorenal conditions and prior to adjustment, persons with ASCVD, HF and kidney disease incurred healthcare costs that were approximately 2.2, 3.3, and 2.7 times greater. After adjustment, comorbid ASCVD, HF and kidney disease were associated with annual excess spending of $8651 (95% CI $7729-$9573), $9373 (95% CI $9010-$9736), and $9995 (95% CI $8781-$11,209), respectively. CONCLUSIONS Study results are generalizable to non-institutionalized US persons. Healthcare costs associated with the management of diabetes are high-especially among those with comorbid cardiorenal conditions, and have risen in recent years.

Causal associations between age at diagnosis of diabetes and cardiovascular outcomes: a Mendelian randomization study. J Clin Endocrinol Metab 2022; 108:1202-1214.

Abstract
CONTEXT Whether diabetes diagnosed at different age groups is causally associated with cardiovascular diseases (CVDs) is unknown. OBJECTIVE We conducted two-sample Mendelian randomization analyses to investigate the causal associations of diabetes by age at diagnosis with five type-specific CVDs and 11 cardiometabolic traits. METHODS We selected 208 single nucleotide polymorphisms (SNPs) for diabetes and 3, 21, 57, and 14 SNPs for diabetes diagnosed at <50, 50-60, 60-70, and >70 years, respectively, based on the GWAS (24,986 cases/187,130 controls) in the UK Biobank, and extracted genetic associations with stroke, myocardial infarction, heart failure, atrial fibrillation, and CVD mortality, as well as blood pressures, adiposity measurements, and lipids and apolipoproteins from corresponding European-descent GWASs. The inverse-variance weighted method was used as main analysis with several sensitivity analyses. RESULTS Diabetes diagnosed at all four age groups was causally associated with increased risks of stroke (5%-8%) and myocardial infarction (8%-10%), higher systolic blood pressure (0.56-0.94 mmHg) and waist-to-hip ratio (0.003-0.004), and lower body mass index (0.31-0.42 kg/m2), waist circumference (0.68-0.99 cm), and hip circumference (0.57-0.80 cm). Diabetes diagnosed at specific age groups was causally associated with increased risks of heart failure (4%) and CVD mortality (8%), higher diastolic blood pressure (0.20 mmHg) and triglycerides (0.06 SD), and lower high-density lipoprotein cholesterol (0.02 mmol/L). The effect sizes of genetically determined diabetes on CVD subtypes and cardiometabolic traits were comparable and the corresponding 95% confidence intervals largely overlapped across the four age groups. CONCLUSION Our findings provide novel evidence that genetically determined diabetes subgroups by age at diagnosis have similar causal effects on CVD and cardiometabolic risks.

Abstract
AIMS To compare the prevalence and risk of diabetic complications between people with young-onset and late-onset type 2 diabetes mellitus (T2DM). METHODS In this observational study, 10,447 people with T2DM had at least one study of diabetic complications: retinopathy, neuropathy, chronic kidney disease (CKD), carotid artery plaque. We use odds ratios to compare complications between young-onset T2DM (YOD) and late-onset T2DM (LOD). RESULTS We compare 1,791 people with YOD (diagnosed < 40 years) and 8,656 with LOD (diagnosed ≥ 40 years). The YOD had a higher prevalence of these complications than the LOD (p < 0.011) after adjustment for confounding factors. Further adjustment for diabetes duration greatly attenuated the odds ratios however, neuropathy remained significantly more frequent in people with YOD (adjusted odds ratio: 1.39, 95% confidence interval: 1.13-1.71, p = 002). In cluster analysis on the 2,126 study participants who were diagnosed with T2DM within the previous two years, 47% of the YOD group were in the severe insulin-deficient diabetes cluster in comparison to 23% LOD; 28% and 44% respectively were in the mild age-related diabetes. CONCLUSION People with YOD had a higher prevalence of complications than those with LOD, but this was mostly attributed to a longer duration of diabetes. However, the prevalence of neuropathy remained significantly higher even after adjusting for factors including the duration of diabetes.

Abstract
BACKGRUOUND The prevalence of young-onset diabetes (YOD) has been increasing worldwide. As the incidence of YOD increases, it is necessary to determine the characteristics of YOD and the factors that influence its development and associated complications. METHODS In this retrospective study, we recruited patients who were diagnosed with type 2 diabetes mellitus between June 2001 and December 2021 at a tertiary hospital. The study population was categorized according to age: YOD (age <40 years), middle-age-onset diabetes (MOD, 40≤ age <65 years), and late-onset diabetes (LOD, age ≥65 years). We examined trends in glycemic control by analyzing fasting glucose levels during the first year in each age group. A Cox proportional-hazards model was used to determine the relative risk of developing complications according to glycemic control trends. RESULTS The fasting glucose level at the time of diagnosis was highest in the YOD group (YOD 149±65 mg/dL; MOD 143±54 mg/dL; and LOD 140±55 mg/dL; p=0.009). In the YOD group, glucose levels decreased at 3 months, but increased by 12 months. YOD patients and those with poor glycemic control in the first year were at a higher risk of developing complications, whereas the risk in patients with LOD was not statistically significant. CONCLUSION YOD patients had higher glucose levels at diagnosis, and their glycemic control was poorly maintained. As poor glycemic control can influence the development of complications, especially in young patients, intensive treatment is necessary for patients with YOD.

Abstract
Nearly half of all adults with type 2 diabetes mellitus (T2DM) live in India and China. These populations have an underlying predisposition to deficient insulin secretion, which has a key role in the pathogenesis of T2DM. Indian and Chinese people might be more susceptible to hepatic or skeletal muscle insulin resistance, respectively, than other populations, resulting in specific forms of insulin deficiency. Cluster-based phenotypic analyses demonstrate a higher frequency of severe insulin-deficient diabetes mellitus and younger ages at diagnosis, lower β-cell function, lower insulin resistance and lower BMI among Indian and Chinese people compared with European people. Individuals diagnosed earliest in life have the most aggressive course of disease and the highest risk of complications. These characteristics might contribute to distinctive responses to glucose-lowering medications. Incretin-based agents are particularly effective for lowering glucose levels in these populations; they enhance incretin-augmented insulin secretion and suppress glucagon secretion. Sodium-glucose cotransporter 2 inhibitors might also lower blood levels of glucose especially effectively among Asian people, while α-glucosidase inhibitors are better tolerated in east Asian populations versus other populations. Further research is needed to better characterize and address the pathophysiology and phenotypes of T2DM in Indian and Chinese populations, and to further develop individualized treatment strategies.

Abstract
AIM This study investigated whether rare, deleterious variants in monogenic diabetes-genes are associated with early-onset type 2 diabetes (T2D). METHODS A nested case-control study was designed from 9,712 Italian patients with T2D. Individuals with age at diabetes onset ≤35 yrs (n=300; cases) or ≥65 yrs (n=300; controls) were selected and screened for variants in 27 monogenic diabetes-genes by targeted resequencing. Rare (minor allele frequency-MAF <1%) and possibly deleterious variants were collectively tested for association with early-onset T2D. The association of a genetic risk score (GRS) based on 17 GWAS-SNPs for T2D was also tested. RESULTS When all rare variants were considered together, each increased the risk of early-onset T2D by 65% (allelic OR =1.64, 95% CI: 1.08-2.48, p=0.02). Effects were similar when the 600 study participants were stratified according to their place of recruitment (Central-Southern Italy, 182 cases vs. 142 controls, or Rome urban area, 118 vs. 158, p for heterogeneity=0.53). Progressively less frequent variants showed increasingly stronger effects in the risk of early-onset T2D for those with MAF <0.001% (OR=6.34, 95% CI: 1.87-22.43, p=0.003). One unit of T2D-GRS significantly increased the risk of early-onset T2D (OR 1.09, 95% CI: 1.01-1.18; p=0.02). This association was stronger among rare variants carriers as compared to non-carriers (p=0.02). CONCLUSION Rare variants in monogenic-diabetes genes are associated with an increased risk of early-onset T2D, and interact with common T2D susceptibility variants in shaping it. These findings might help develop prediction tools to identify individuals at high risk of developing T2D in early adulthood.

Abstract
OBJECTIVES There is increasing attention on association between eating patterns and diabetes control following global changes in eating patterns. There had been very limited research on the eating patterns of diabetic patients with employment, although working age population has seen the highest increase in diabetes incidence. This study aimed to identify workplace eating patterns in relation to glycaemic control among type 2 diabetic patients with employment. METHODS This is a sequential mixed-methods study. The exploratory qualitative study involved focus group interviews with 31 type 2 diabetic patients with employment, which guided the design of a subsequent cross-sectional investigation involving 185 patients with employment. Thematic analysis was conducted on the qualitative data to identify workplace eating patterns most relevant to glycaemic control. Hierarchical multiple linear regression was performed to examine association between workplace eating pattern and glycaemic control, proxied by HbA1c. RESULTS The focus group interviews identified frequency in the consumption of home-prepared meals (HPM) and meal hours as the major workplace eating patterns that affected glycaemic control. The cross-sectional study confirmed that regular consumption of HPM at workplace could explain variance of HbA1c, independent of socio-demographic factors, lifestyle factors and disease condition, with R2 = 0.146, F(14, 170) = 2.075, p = 0.015; adjusted R2 = 0.076. Patients who were female, in non-skilled occupation, on shift, with fixed work location and had break during work were more likely to consume HPM. CONCLUSIONS Consumption of HPM at workplace should be promoted to facilitate better glycaemic control by type 2 diabetic patients with employment, possibly through more practical dietary advice, and workplace accommodation in terms of space and facilities. In the context of COVID-19 pandemic, consumption of HPM also meant additional protection for diabetic patients through reducing close contact exposures in restaurants.

Age at diagnosis of type 2 diabetes and cardiovascular risk factor profile: A pooled analysis. World J Diabetes 2022; 13:260-271.

Abstract
BACKGROUND The diagnosis of type 2 diabetes (T2D) in younger adults, an increasingly common public health issue, is associated with a higher risk of cardiovascular complications and mortality, which may be due to a more adverse cardiovascular risk profile in individuals diagnosed at a younger age.
AIM To investigate the association between age at diagnosis and the cardiovascular risk profile in adults with T2D.
METHODS A pooled dataset was used, comprised of data from five previous studies of adults with T2D, including 1409 participants of whom 196 were diagnosed with T2D under the age of 40 years. Anthropometric and blood biomarker measurements included body weight, body mass index (BMI), waist circumference, body fat percentage, glycaemic control (HbA1c), lipid profile and blood pressure. Univariable and multivariable linear regression models, adjusted for diabetes duration, sex, ethnicity and smoking status, were used to investigate the association between age at diagnosis and each cardiovascular risk factor.
RESULTS A higher proportion of participants diagnosed with T2D under the age of 40 were female, current smokers and treated with glucose-lowering medications, compared to participants diagnosed later in life. Participants diagnosed with T2D under the age of 40 also had higher body weight, BMI, waist circumference and body fat percentage, in addition to a more adverse lipid profile, compared to participants diagnosed at an older age. Modelling results showed that each one year reduction in age at diagnosis was significantly associated with 0.67 kg higher body weight [95% confidence interval (CI): 0.52-0.82 kg], 0.18 kg/m2 higher BMI (95%CI: 0.10-0.25) and 0.32 cm higher waist circumference (95%CI: 0.14-0.49), after adjustment for duration of diabetes and other confounders. Younger age at diagnosis was also significantly associated with higher HbA1c, total cholesterol, low-density lipoprotein cholesterol and triglycerides.
CONCLUSION The diagnosis of T2D earlier in life is associated with a worse cardiovascular risk factor profile, compared to those diagnosed later in life.

Abstract
BACKGROUND Currently, the status and principal factors of psychosocial adjustment of young and middle-aged patients after coronary stent implantation (CSI) are understudied. OBJECTIVE To investigate the psychosocial adjustment and the life experiences of young and middle-aged patients after CSI and the corresponding support necessary to maintain psychosocial health for this patient population. METHODS This is a mixed-method study. Self-reported questionnaires were used to survey 236 patients after CSI from November 2019 to November 2020 in Guangdong, China. Eight of these patients were purposefully invited to participate in semi-structured interviews. RESULTS The mean score of psychosocial adjustment were 55.25 (SD=19.96), 55.91 (SD=17.99) for the young and middle-aged patients after CSI respectively. The results of regression analysis showed that resilience, social support, and having diabetes were predictors of psychosocial adjustment of young patients after CSI (R2=0.703, P<0.001). Resilience, social support, current cardiac function, and need to care for parents with chronic diseases were identified as predictors of psychosocial adjustment among middle-aged patients after CSI (R2=0.640, P<0.001). Two themes and six sub-themes related to adjustment challenges and adjustment efforts were identified from the in-depth interviews. CONCLUSIONS Psychosocial adjustment of young and middle-aged patients after CSI still needs to be improved. Higher level of social support and resilience would promote patient's psychosocial adjustment after CSI. Diabetes was a negative factor of psychosocial adjustment in young patients, whereas limited cardiac function, need to take care of parents with chronic diseases were negative factors in middle-aged patients. After CSI, both young and middle-aged patients faced various challenges of adjustment.

Abstract
Aims/Introduction To assess the relationship between type 2 diabetes mellitus onset age and vascular complications in China. Materials and Methods A retrospective review of 3,568 patients with type 2 diabetes mellitus using a propensity score‐matched (PSM) cohort analysis was carried out in two different age of onset groups (age 40 and 60 years). These groups were then subdivided into two groups, early‐onset diabetes (EOD40 and EOD60; the onset age before 40 and 60 years, respectively) and late‐onset diabetes (LOD40 and LOD60: the onset age after 40 and 60 years, respectively). Macrovascular and microvascular complications were analyzed before and after PSM. Results Patients categorized in both the early‐onset disease (EOD) groups had a higher risk of developing macro‐ and microvascular complications before PSM. After PSM, no differences existed between the EOD and late‐onset disease groups in the risk of macrovascular complications. Compared with the late‐onset disease group, the odds ratio of having a microvascular complication of diabetic retinopathy, chronic kidney disease and diabetic peripheral neuropathy in the 40‐year‐old EOD group increased to 2.906, 1.967 and 1.672 (P < 0.05), respectively. The odds ratio of diabetic retinopathy and diabetic peripheral neuropathy in the 60‐year‐old EOD group was 1.763 and 1.675 (P < 0.05), respectively. Conclusions The earlier the onset of type 2 diabetes mellitus, the higher risk of microvascular, but not necessarily macrovascular, complications. It is not too late to prevent diabetes at any age. Pre‐emptive microvascular treatment or preventative measures in EOD patients who do not yet show symptoms, might be beneficial.

Abstract
Several factors, including genetics, family history, diet, physical activity, obesity, and insulin resistance in puberty, appear to increase the risk of type 2 diabetes in youth. Youth-onset type 2 diabetes is often thought of as a single entity but rather exists as a spectrum of disease with differences in presentation, metabolic characteristics, clinical progression, and complication rates. We review what is currently known regarding the risks associated with developing type 2 diabetes in youth. Additionally, we focus on the spectrum of phenotypes of pediatric type 2 diabetes, discuss the pathogenic underpinnings and potential therapeutic relevance of this heterogeneity, and compare youth-onset type 2 diabetes with type 1 diabetes and adult-onset type 2 diabetes. Finally, we highlight knowledge gaps in prediction and prevention of youth-onset type 2 diabetes.

Abstract
CONTEXT Early-onset diabetes has been associated with unfavorable cardiovascular risk but data on heart failure (HF) in this subpopulation are scarce. OBJECTIVE We aimed to study the risk of, and risk factors for, incident HF in individuals with early-onset type 2 diabetes. METHODS We studied 606 individuals with type 2 diabetes diagnosed before 40 years of age (early-onset) and 1258 counterparts with diabetes diagnosed from 41 to 65 years of age (usual-onset) with no HF history, at a regional hospital, over a median follow-up period of 7.1 years. Incident HF by European Cardiology Society criteria was determined. RESULTS A total of 62 and 108 HF events were identified in the early- and usual-onset groups (1.55 and 1.29 per 100 patient-years), respectively. Compared with usual-onset counterparts, individuals with early-onset diabetes had a 1.20-fold unadjusted (95% CI, 0.88-1.63; P = 0.26) and 1.91-fold age-adjusted (95% CI, 1.37-2.66; P < 0.001) hazard ratio (HR) for incident HF. Adjustment for traditional cardiometabolic risk factors only moderately mitigated the hazards (adjusted HR 1.69; 95% CI, 1.19-2.40; P = 0.003). However, additional adjustment for estimated glomerular filtration rate and albuminuria markedly attenuated the association of early-onset age with incident HF (adjusted HR 1.24; 95% CI, 0.87-1.77; P = 0.24). Notably, a long diabetes duration was not significantly associated with HF risk after accounting for kidney measures. CONCLUSION Individuals with early-onset diabetes have at least the same absolute risk and a 2-fold age-adjusted relative risk for incident HF. Excess cardiorenal risk factors but not a long diabetes duration are main drivers for HF development in this diabetic population.

Non-skilled occupation as a risk factor of diabetes among working population: A population-based study of community-dwelling adults in Hong Kong. HEALTH & SOCIAL CARE IN THE COMMUNITY 2022; 30:e86-e94. [PMID: 34169598 PMCID: PMC9291875 DOI: 10.1111/hsc.13415] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/08/2020] [Revised: 03/05/2021] [Accepted: 04/04/2021] [Indexed: 06/13/2023]
Abstract
Diabetes among working population brings to society concerns on productivity and social welfare cost, in addition to healthcare burden. While lower socio-economic status has been recognised as a risk factor of diabetes; occupation, compared with other socio-economic status indicators (e.g., education and income), has received less attention. There is some evidence from studies conducted in Europe that occupation is associated with diabetes risk, but less is known in Asia, which has different organisational cultures and management styles from the West. This study examines the association between occupation and diabetes risk in a developed Asian setting, which is experiencing an increasing number of young onset of diabetes and aging working population at the same time. This is a cross-sectional study of working population aged up to 65 with data from a population-based survey collecting demographic, socio-economic, behavioural and metabolic data from Hong Kong residents, through both self-administered questionnaires and clinical health examinations (1,429 participants). Non-skilled occupation was found to be an independent risk factor for diabetes, with an odds ratio (OR) of 3.38 (p < 0.001) and adjusted OR of 2.59 (p = 0.022) after adjusting for demographic, behavioural and metabolic risk factors. Older age (adjusted OR = 1.08, p < 0.001), higher body mass index (adjusted OR = 1.23, p < 0.001) and having hypertriglyceridemia (adjusted OR = 1.93, p = 0.033) were also independently associated with diabetes. Non-skilled workers were disproportionately affected by diabetes with the highest age-standardized prevalence (6.3%) among all occupation groups (4.9%-5.0%). This study provides evidence that non-skilled occupation is an independent diabetes risk factor in a developed Asian setting. Health education on improving lifestyle practices and diabetes screening should prioritise non-skilled workers, in particular through company-based and sector-based diabetes screening programmes. Diabetes health service should respond to the special needs of non-skilled workers, including service at non-office hour and practical health advice in light of their work setting.

Abstract
Left-truncated data are often encountered in epidemiological cohort studies, where individuals are recruited according to a certain cross-sectional sampling criterion. Length-biased data, a special case of left-truncated data, assume that the incidence of the initial event follows a homogeneous Poisson process. In this article, we consider an analysis of length-biased and interval-censored data with a nonsusceptible fraction. We first point out the importance of a well-defined target population, which depends on the prior knowledge for the support of the failure times of susceptible individuals. Given the target population, we proceed with a length-biased sampling and draw valid inferences from a length-biased sample. When there is no covariate, we show that it suffices to consider a discrete version of the survival function for the susceptible individuals with jump points at the left endpoints of the censoring intervals when maximizing the full likelihood function, and propose an EM algorithm to obtain the nonparametric maximum likelihood estimates of nonsusceptible rate and the survival function of the susceptible individuals. We also develop a novel graphical method for assessing the stationarity assumption. When covariates are present, we consider the Cox proportional hazards model for the survival time of the susceptible individuals and the logistic regression model for the probability of being susceptible. We construct the full likelihood function and obtain the nonparametric maximum likelihood estimates of the regression parameters by employing the EM algorithm. The large sample properties of the estimates are established. The performance of the method is assessed by simulations. The proposed model and method are applied to data from an early-onset diabetes mellitus study.

Abstract
AIM To compare long-term outcomes among three groups with different ages of diabetes onset. METHOD 66,520 paired age-, and sex-matched persons with and without type 2 diabetes were selected from the Taiwan National Health Insurance Research Database from 2000 to 2012. Cox proportional hazards models were used to compare the outcomes. Using late-onset diabetes as a reference, adjusted difference in differences analyses were performed to assess excessive odds comparing diabetes versus non-diabetes for young-onset diabetes (YOD) and early-onset diabetes in the risks of mortality and vascular complications. RESULTS Persons with type 2 diabetes, irrespective of the onset age, had higher associated risks of all-cause mortality and vascular complications than their matched counterparts without diabetes. Compared to the odds of complications between those with diabetes and non-diabetes in the late-onset diabetes group, the excess odds in YOD are generally greater than in the early-onset diabetes (for stroke: 1.90 vs. 1.32; heart failure: 2.03 vs. 1.58; myocardial infarction: 3.02 vs. 1.56; and microvascular complications: 3.52 vs. 3.01). CONCLUSIONS Diabetes with different ages of onset may imply distinct long-term health outcomes. The persons with young-onset and early-onset diabetes seem to bear excess risk for mortality and vascular complications.
