To examine the impact of the integrated urban-rural health insurance policy on depression levels among rural middle-aged and elderly populations.
A multi-period difference-in-differences model was constructed using five waves of the China Health and Retirement Longitudinal Study (CHARLS) data from 2011-2020 to evaluate policy effects.
The integration policy reduced depression scores among rural middle-aged and elderly individuals by 0.426 points (β=-0.426, P<0.05), with significant effects observed among rural males (β=-0.416, P<0.01) and middle-aged cohorts (β=-0.570, P<0.1). Improved chronic disease conditions partially mediated this effect.
The integration of health insurance significantly reduces depression levels among rural middle-aged and elderly individuals. Future efforts should focus on deepening institutional reforms, optimizing chronic disease coverage, and strengthening targeted interventions to enhance the physical and mental health security of this demographic.
