To assess the association between the trajectories of depression symptoms and the risk of stroke in the elderly.
Data from four waves of the China Health and Retirement Longitudinal Study (CHARLS) from 2011 to 2018 were utilized.Group-based trajectory modeling was employed to identify the trajectories of depression symptoms, and logistic regression models were used to evaluate the relationship between these trajectories and stroke.
Four trajectories of depression symptoms were identified:low stable (n=2 392, 60.7%), moderate decreasing (n=762, 20.2%), moderate increasing (n=416, 12.3%), and high stable (n=250, 6.8%).During the period from 2015 to 2018, a total of 305 respondents experienced a stroke. Compared to participants with the low stable depression symptom trajectory, those following the moderate decreasing (OR=1.48, 95%CI: 1.09-2.02), moderate increasing (OR=2.22,95%CI: 1.58-3.11), and high stable depression symptom trajectories (OR=1.78, 95%CI: 1.12-2.83) had a higher risk of stroke.
Over time, elderly individuals following moderate decreasing, moderate increasing, and high stable trajectories of depression symptoms exhibited an increased risk of stroke. Long-term depression symptoms may serve as a strong predictor for stroke.
