Physical activity (PA) is an established protective factor for many chronic diseases. Numerous studies have established positive relationships between social networks and PA. Accordingly, this study examined the relationship between social network structures (specifically the network size and the number and proportion of same-sex alters) and self-reported PA in Korean middle-age adults, where the term "alter" refers to a respondent's social network members.
We analyzed 8,092 participants of the Cardiovascular and Metabolic Diseases Etiology Research Center cohort. We assessed the association between each network structure variable and PA level using a linear regression model. Then, we employed logistic regression to evaluate associations between social network structure and adherence to guideline-recommended exercise levels. Socio-demographic factors and health status measures were used as covariates.
In both sexes, the social network size and proportion of same-sex network members showed positive relationships with total and moderate-to-vigorous PA. Notably, female participants with a greater number of kin were more likely to satisfy the recommended amount of total PA.
These findings suggest that large scale, same-sex intervention programs can help to achieve recommended PA regimens.
身体活动（PA）是许多慢性病的既定保护因素。许多研究已经建立了社会网络与 PA 之间的积极关系。因此，本研究调查了韩国中年成年人的社会网络结构（特别是网络规模以及同性联系人的数量和比例）与自我报告的 PA 之间的关系，其中“联系人”是指受访者的社交网络成员。
我们分析了心血管和代谢疾病病因研究中心队列的 8092 名参与者。我们使用线性回归模型评估了每个网络结构变量与 PA 水平之间的关联。然后，我们采用逻辑回归评估了社会网络结构与遵循指南推荐的运动水平之间的关联。社会人口统计学因素和健康状况衡量标准被用作协变量。
在男性和女性中，社会网络规模和同性联系人的比例与总 PA 和中高强度 PA 呈正相关。值得注意的是，具有更多亲属的女性参与者更有可能满足总 PA 的推荐量。
这些发现表明，大规模的同性干预计划可以帮助实现推荐的 PA 方案。
