The health effect of perceived built environment on depression of elderly people in rural China: Moderation by income.

This study explored the health effect of perceived built environment on depression of the Chinese elderly people in rural areas. A multifaceted approach in examining perceived built environment was used. A sample of 670 older residents in rural area of China were interviewed, and data were collected mainly for exploratory factor analysis, confirmatory factor analysis and moderation analysis. Results showed a reliable construct of perceived built environment which was developed by this study. A significant moderating role of personal income per month in the significantly negative relationship between perceived built environment and depression was confirmed. That is, the health effect of perceived built environment on depression became weakened among people of higher income levels. This study added evidence for the health effect of perceived built environment on depression among Chinese elderly people. Additionally, individual income was identified as an important influencing factor in such effect. Discussion on the negative relationship between perceived built environment and depression, as well as the moderating effect of personal income in such relationship were presented.
