The rapid aging of the global population presents pressing public health challenges, notably an increase in suicide rates among older adults. Despite this critical issue, there is a scarcity of comprehensive assessments regarding the existing literature on suicide within this demographic. This study seeks to employ bibliometric analysis and knowledge mapping to elucidate prevailing research trends and the overall status of this field.

We performed a comprehensive computer-based search of the Web of Science Core Collection to identify relevant articles and reviews concerning suicide in the elderly. A bibliometric analysis was conducted, examining various aspects including countries or regions, institutions, authors, journals, keywords, and references. This analysis utilized tools such as CiteSpace, VOSViewer, Pajek, and Excel 365 to facilitate a thorough assessment.

The analysis covered 1,116 publications from 2005 to 2024. The annual number of publications showed a fluctuating upward trend, with notable decreases in 2007, 2012, 2015, 2017, and 2022, and increases in 2009, 2013, 2016, and 2019, peaking at 121 in 2021, with citations reaching 4,741 in 2022, but declining since then. The United States stands out as the most productive and influential country in the field, boasting the highest number of publications and citations. The country is home to institutions leading in both publication and citation metrics. Prominent authors contributing significantly to this domain include Conwell Yeates, Van Orden Kimberly A., and Waern Margda. Key journals disseminating crucial research are the Journal of Affective Disorders, American Journal of Geriatric Psychiatry, and Lancet. Frequent keywords in this field encompass depression, suicidal ideation, suicide, older-adults, risk, risk factors, prevalence, older adults, ideation, behavior, health, mental health, life, age, people, prevention, symptoms, scale, population, and elderly. The contemporary research emphasis is primarily on identifying, treating, and preventing the suicide risk associated with depression in older adults.

This study highlights the growing research focus on suicide in older adults, particularly related to depression and the identification, treatment, and prevention of suicide risk. The findings underscore the need for targeted prevention strategies and further investigation in this critical public health area.

Suicidal behavior in older adults is a fundamental public health problem globally and the highest suicide rates occur in low- and middle-income countries (LMICs). However, there is limited research on suicidality among older adults, especially in sub-Saharan Africa. We sought to find out whether loneliness, stress and religiosity would be associated with suicide ideation in a sample of sub-Saharan African older adults (N = 500; aged 51-70 years, Mage = 58.97, SD = 6.16; 45.6% women). They completed the Beck Suicidal Ideation Scale, the UCLA Loneliness Scale-version 3, Perceived Stress Scale, and Religiosity Scale. Regression results showed that whereas suicidal ideation could be increased by loneliness and stress, religious older adults were less likely to report suicidal ideation. Interventions aimed at managing and protecting the mental health of older adults during their transition to late adulthood should guard them against loneliness and buffer their resilience and coping strategies with the connectedness that religiosity offers.

The aim of the present study was to investigate associations between food insecurity with suicidal ideation and suicide attempts in adults aged ≥50 years from six low- and middle-income countries (LMICs).

Cross-sectional, community-based data from the World Health Organisation's Study on Global Aging and Adult Health were analyzed. Self-reported information on past 12-month suicidal ideation and suicide attempts was collected. Past 12-month food insecurity was assessed with two questions on frequency of eating less and hunger due to lack of food. Multivariable logistic regression analysis was conducted to assess the association between food insecurity and suicidal ideation or suicide attempts.

The final analytical sample included 34,129 individuals aged ≥50 years [mean (SD) age 62.4 (16.0) years; 52.1% females]. Compared to no food insecurity, severe food insecurity was associated with a significant 2.78 (95%CI = 1.73-4.45) times higher odds for suicidal ideation, while moderate and severe food insecurity were associated with 2.59 (95%CI = 1.35-4.97) and 5.15 (95%CI = 2.52-10.53) times higher odds for suicide attempts, respectively.

The cross-sectional design, the use of self-reported wish to die as a measure of suicide ideation, and that suicidal ideation and suicide attempts were only assessed among those who had depressive symptoms, could be considered limitations of our study.

Food insecurity was positively associated with suicidal ideation and suicide attempts. Targeting food insecurity among older adults in LMICs may lead to reduction in suicidal ideation and suicide attempts, although future longitudinal studies are warranted to confirm this.

Suicide is a leading cause of preventable death worldwide, with its peak of maximum incidence in later life. Depression often puts an individual at higher risk for suicidal behaviour. In turn, depression deserves particular interest in old age due to its high prevalence and dramatic impact on health and wellbeing.

To gather integrated evidence on the potential risk factors for suicide behaviour development in depressive older adults, and to examine the effects of depression treatment to tackle suicide behaviour in this population.

A systematic review of empirical studies, published from 2000 onwards, was conducted. Suicidal behaviour was addressed considering its varying forms (i.e., wish to die, ideation, attempt, and completed suicide).

Thirty-five papers were selected for review, comprising both clinical and epidemiological studies. Most of studies focused on suicidal ideation (60%). The studies consistently pointed out that the risk was related to depressive episode severity, psychiatric comorbidity (anxiety or substance use disorders), poorer health status, and loss of functionality. Reduced social support and loneliness were also associated with suicide behaviour in depressive older adults. Finally, the intervention studies showed that suicidal behaviour was a robust predictor of depression treatment response. Reductions in suicidal ideation were moderated by reductions in risk factors for suicide symptoms.

To sum up, common and age-specific risk factors seem to be involved in suicide development in depressive older adults. A major effort should be made to tackle this serious public health concern so as to promote older people to age healthily and well.

There is currently limited literature on the association between visual impairment and suicidal thoughts and behaviours, especially among older adults from low/middle-income countries (LMICs). Thus, we aimed to investigate the associations of objectively measured distance visual impairment with suicidal ideation and suicide attempts among adults aged ≥50 years from six LMICs and to identify potential mediators.

Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health were analysed. Objective distance visual acuity was measured using the tumbling E logMAR chart, and vision impairment was categorised as none, mild, moderate and severe. Self-reported information on past 12-month suicidal ideation and suicide attempts was also collected. Multivariable logistic regression and mediation analysis were conducted.

Data on 34 129 individuals aged ≥50 years (mean (SD) age, 62.4 (16.0) years; 47.9% men) were analysed. After adjustment for potential confounders, compared with no visual impairment, severe visual impairment was significantly associated with suicidal ideation (OR=9.50; 95% CI=2.47 to 36.52). Moderate and severe visual impairment were significantly associated with a 2.22 (95% CI=1.14 to 4.35) and 11.50 (95% CI=1.44 to 91.88) times higher odds of suicide attempts, respectively. Disability, poor self-rated health, mobility and loneliness explained 14.0%, 9.3%, 7.2% and 6.3% of the association between moderate/severe visual impairment and suicide attempts, respectively.

Interventions to reduce suicidal ideation and suicide attempts among older adults with visual impairment in LMICs are required, targeting identified mediators, while using tested strategies for suicide prevention per se in LMICs may yield beneficial outcomes.

The authors conducted a literature review on the theme of violence and health published in the Brazilian public health journal "Ciência & Saúde Coletiva" (C&SC) from 1996 to 2019. The search also included two other Brazilian journals, "Cadernos de Saúde Pública" (CSP) and "Revista de Saúde Pública" (RSP) and two international journals, the "American Journal of Public Health" (AJPH) and the "Pan American Journal of Public Health" (PAJPH), totaling 1,179 articles. The analysis aggregated each journal's material in eleven themes, based on conceptual affinity. For the articles from C&SC, the authors analyzed variables such as year of publication, area of knowledge, institution's region, study scope, methodology, and target population. The analysis found that C&SC gave visibility to violence and health, standing out from the other journals since 2009. External causes, children and adolescents, quantitative studies, municipal and national scope, and institutions located in the Southeast region of Brazil predominated. There are gaps in topics such as self-mutilation and vulnerable populations, among other areas where more studies and publications should be encouraged.
