ARTICLE HIGHLIGHTS
Research background
Type 2 diabetes mellitus (T2DM) is an established risk factor for the development of nonalcoholic fatty liver disease (NAFLD). Both synergistically increase adverse outcomes.
Research motivation
The prevalence of NAFLD assessed by computed tomography (CT) was reported only in a few studies. The clinical correlates of NAFLD are often ambiguous.
Research objectives
To determine the prevalence and clinical correlates of NAFLD assessed by CT in a large cohort of T2DM patients.
Research methods
Four hundred thirty-seven participants with T2DM who consulted at Meijo Hospital from April 2019 to September 2020 and underwent CT were assessed.
Research results
The prevalence of NAFLD as detected by CT was 25.2% in T2DM patients, and NAFLD was associated with a younger age, higher hemoglobin levels, lower high density lipoprotein cholesterol levels, and absence of dialysis treatment.
Research conclusions
The prevalence of NAFLD in T2DM is higher than in the general population considering older age and decreases with age.
Research perspectives
The association of NAFLD with age has to be clarified by prospective cohort studies.
