To explore the bidirectional association between metabolic syndrome(MS) and depression in middle-aged and elderly adults in China.
This study used participants aged 45 and above from publicly available longitudinal data from the China Health and Retirement Longitudinal Study(CHARLS) from 2011 to 2018. The baseline was based on 2011 data. Stage I studied the longitudinal association of baseline MS with follow-up depression, while Stage II studied the association of baseline depression with follow-up MS. Stage III further investigated the bidirectional association between MS and depression using a cross-lagged panel model, and the follow-up data for all three stages used 2015 data including blood routine examination and physical examinations.
There was a bidirectional association between the two diseases. The baseline MS and its components showed a positive correlation with the follow-up depression(β=0.052, P<0.01), and vice versa(β=0.305, P<0.01), but there were differences in gender subgroups.
There is a bidirectional correlation between MS and its components and depression in the middle-aged and elderly population in China. We should identify, monitor, and intervene in early MS and depression.
