Abstract:

Objective To explore the correlation between social activities and heart disease in Chinese people aged 45 years and above, thus providing reference data for the prevention of heart disease. Methods A cross-sectional study was conducted with data from the 2020 China Health and Retirement Longitudinal Study (CHARLS). Demographic characteristics, living habits, social activities and other indicators were compared. Multivariate Logistic regression was performed to analyze the influencing factors with stepwise adjustments for confounders like gender and age. Correlation of seven types of social activities with heart disease in middle-aged and elderly people was identified. Results A total of 18, 298 study participants were enrolled, with the prevalence of heart disease of 19.46%(3, 561/18, 298). There was a significant difference in the prevalence of heart disease between individuals who were participated in different social activities (e.g., providing free assistance to relatives, friends, or neighbors who do not live with you, or engagement in training courses) and those did not involve in social activities (P<0.01). Multivariate logistic regression analysis showed that after adjusting for sex, age and other confounders, providing free assistance to relatives, friends, or neighbors who do not live with you (OR=0.82, 95%CI=0.73-0.91, P<0.01), and engagement in training courses (OR=0.71, 95%CI=0.50-0.99, P=0.044) were negatively correlated with the risk of heart disease; while playing mahjong, playing chess, playing cards, and going to community activity rooms were positively correlated with the risk of heart disease (OR=1.10, 95%CI=0.99-1.23, P=0.046). Conclusion In the middle-aged and elderly population, strengthening social support networks and encouraging knowledge-based social participation may be an effective intervention direction for cardiovascular disease prevention, providing a theoretical basis for constructing a multidimensional healthy aging strategy.
