Prevalence and risk of diabetic complications in young-onset versus late-onset type 2 diabetes mellitus

초록

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 complica-tions: 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 how-ever, 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 diag-nosed 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 signifi-cantly higher even after adjusting for factors including the duration of diabetes.(c) 2022 Elsevier Masson SAS. All rights reserved.
