Public Sports Facility Availability in Living Communities and Mental Health of Older People in China: The Mediating Effect of Physical Activity and Life Satisfaction.

The aging of China's population has created significant challenges for the mental health of older adults. However, limited research has examined how public sports facility availability in living communities supports older adults' mental health. To explore this association, data were extracted from the 2016 China Longitudinal Aging Social Survey, which involved 7811 respondents. The ordinary least squares model and the instrumental variable approach were employed to test the association between public sports facility availability in Chinese older adults' living communities and their mental health. The bootstrapping method was used to estimate the mediating effect of physical activity and life satisfaction. The results indicate that public sports facility availability in living communities was significantly correlated with a decrease in depressive symptoms among older people (coefficient = -0.225; < 0.01), which suggests that a greater availability of public sports facilities in living communities is related to the better mental health of older adults. The results of the mediation analysis show that physical activity and life satisfaction were identified as mediating mechanisms. This study suggests that increasing the availability of public sports facilities in older adults' living communities can alleviate depression and promote better mental health. Our findings provide valuable policy implications for enhancing public sports infrastructure and promoting healthy aging.
