To identify the types of social networks of the elderly in China, to analyze their population distribution characteristics, and to explore the association between different social network types and health behaviors, so as to provide reference for developing personalized health intervention strategies.
Using the data from the 2018 Chinese Longitudinal Healthy Longevity Survey, latent class analysis was used to identify the types of social networks in the elderly. The Multinomial Logistic Regression Analysis and Apriori algorithm were used to analyze the association between different social network types and health-related behaviors.
A total of 6 184 elderly people was included in this study. The social network types of the elderly in China were divided into family type (45.97%), couple type (41.91%) and widowed type (12.12%).Results from the Multinomial Logistic Regression Analysis showed that the elderly who were older (OR=1.141, 95% CI: 1.132-1.149), female (OR=4.472, 95% CI: 3.846-5.201), in ethnic minority (OR=1.454, 95% CI:1.037-2.040), and had sufficient sleep (OR=1.158,95% CI: 1.010-1.328) were more likely of the family-oriented social network. The elderly who were older (OR=1.120, 95% CI: 1.109-1.131), female (OR=4.913, 95% CI: 4.007-6.026) and had sufficient sleep (OR=1.247,95% CI:1.039-1.498) were more likely of the widowed-like social network.Strong association rules of the association rule is: drinking, smoking, and exercise of the elderly social network for couples.
The couple type is more likely to have unhealthy behaviors in the elderly in China, and its social network is smaller and its social support is single. Therefore, it is necessary to enrich the social network, enhance social support, and carry out intergenerational intervention to improve the healthy behavior of the elderly.
