Activity Limitations and Depression Among Middle-Aged and Older Adults in China: The Moderating Impact of Assistance Adequacy.

This study aimed to examine the risk and protective factors associated with depression in middle-aged and older Chinese adults with activity limitations. Data were obtained from the 2018 Wave 4 Survey of the China Health and Retirement Longitudinal Study. In the logistic regression analysis, health and functioning, losing a child, and a perceived lack of future assistance with daily activities increased the odds of depression. Conversely, receiving adequate assistance with daily activities lessened the depressive impacts of activity limitations, as indicated by a significant interaction effect. Enhanced long-term support for individuals with disabilities is necessary to improve mental health.
