Background
The number of empty nesters in China is increasing and their health status is poor relative to that of non-empty nesters. However, older adults are not yet aware of the direct and indirect health-promoting effects of social engagement.
Methods
This study used data from the 2018 China Health and Aging Tracking Survey (CHARLS2018) to first conduct a descriptive analysis of the social engagement status and health status of empty nesters, then analyze the effect of social engagement on the health of empty nesters using a multiple regression model, and conduct robustness tests using propensity score matching methods, and then use a mediating effects model to explore the effect of social engagement on Then, we used the mediating effect model to explore the mechanism of social participation on the health of empty nesters, and finally, we used subsample regression to analyze the heterogeneity of different groups of empty nesters.
Results
First, there is a significant effect of social participation on the health status of the empty nesters, and the effects of various types of health still hold after using the propensity score matching method to deal with the endogeneity problem caused by sample selection; Second, economic income and cognitive ability have a significant mediating effect in the process of social participation affecting the health of the empty nesters; Third, there is age, urban and rural heterogeneity in the effect of social participation on the health of the empty nesters heterogeneity, i.e., social participation had a greater impact on the health of urban empty nesters and social participation had the greatest impact on the health of empty nesters aged 70–79.
Conclusions
These results highlight the facilitative effect of social participation on the health status of empty nesters and clarify the mediating role of cognitive ability and economic income in the influence process.
