To investigate the effect of depressive symptoms on the risk of developing type 2 diabetes mellitus in middle-aged and elderly people in China.
Based on the data from the China Health and Retirement Longitudinal Study (CHARLS) 2011 and 2018, 9 697 middle-aged and elderly people aged 45 years or older were included as study subjects. Chained equations were used to perform g-formula analysis after multiple interpolation of missing values of covariates, and stratified analyses were performed to explore the association between depressive symptoms and the risk of developing type 2 diabetes mellitus with respect to age and gender.
The results of the analysis after multiple interpolation of covariates and adjustment for confounding showedthat the mean risk of developing type 2 diabetes mellitus in study participants with depressive symptoms which was 1.3 times higher than that of those without depressive symptoms [RR(95% CI):1.37(1.15-1.62)], with a mean hazard difference of 0.02. Those with mild depressive symptoms had a mean risk of type 2 diabetes mellitus of 1.27 times higher than that of those without depressive symptoms [RR(95% CI):1.27(1.07-1.52)], with a mean difference of 0.01; those with severe depressive symptoms had a mean risk of developing type 2 diabetes mellitus that was 2.22 times higher than that of those who were not depressed [RR(95% CI):2.22(1.64-3.00)]; the mean difference was 0.06.
Depressive symptoms and the risk of type 2 diabetes mellitus were significantly associated with the risk of developing type 2 diabetes mellitus among middle-aged and elderly people in China. Associated with the risk of developing type 2 diabetes, the risk of developing the disease increased with the severity of depressive symptoms.
