Preventive health behaviors among the middle-aged and elderly in China: Does social capital matter?

This study explores the status quo of preventive care use and social capital among middle-aged and elderly people (≥45 years old) in China, and employs a multi-level model to analyze whether social capital at different levels is associated with preventive care use. The data are derived from the 2018 China Health and Retirement Longitudinal Study (CHARLS), which includes 11,503 respondents and 450 communities. Preventive care use covers the utilization of routine physical examination services. Individual social capital is measured by the level of social network and social activities participation. Social network includes contacting with children or other people, for example, by phone, text message. Social activities participation is measured by the involvement in social activities, for example, playing mahjong, going to community club. Community social capital is evaluated by the richness of community facilities. Results reveals that the utilization of preventive care is 48.94% among middle-aged and elderly in China. The most used preventive service is routine blood test. The intra-class correlation (ICC) coefficient indicates that preventive health behaviors of the respondents are clustered at communities where they live. Multi-level regression shows that influence of social network is not significant to preventive care use (p ＞ 0.05). Community facilities and individual social activities participation are significantly associated with preventive care use (p < 0.05). The association between social capital and preventive care use could be considered as an important factor when making policies to promote preventive care use.
