This study aims to examine the relationship between social activity and the risk of cardiovascular disease (CVD) in middle-aged and older adults in China.
We used data from the China Health and Retirement Longitudinal Study (CHARLS) collected between 2011 and 2020. The study followed 4,099 participants aged 45 and older, all free from cardiovascular disease at baseline (2011), over a 9-year period. CVD status was self-reported by participants. Kaplan-Meier survival curves were employed to illustrate the cumulative incidence of cardiovascular events across different levels of social activity. Cox proportional hazards regression models and restricted cubic spline (RCS) were used to evaluate the association between social activity and CVD risk. Subgroup analyses were conducted to explore potential interactions between social activity and CVD risk, stratified by age, gender, education level, smoking and drinking status, number of chronic conditions, depression, and body mass index (BMI).
A total of 4,099 participants were included in the analysis. Over the 9-year follow-up period, 813 cardiovascular events occurred. After adjusting for age, gender, residence, education, marital status, smoking and drinking habits, chronic disease burden, depression, and BMI, each 0.1 decrease in social activity level was associated with a 7.4% increased risk of cardiovascular events (aHR, 1.074; 95% CI: 1.069-1.079).
Social activity is significantly linked to the risk of cardiovascular disease among middle-aged and older adults in China. These findings emphasize the importance of maintaining social engagement to support cardiovascular health in this population.
本研究旨在探讨中国中老年人群社交活动与心血管疾病（CVD）风险之间的关系。
我们使用了2011年至2020年期间收集的中国健康与养老追踪调查（CHARLS）的数据。该研究对4099名年龄在45岁及以上的参与者进行了为期9年的跟踪，所有参与者在基线时（2011年）均无心血管疾病。心血管疾病状况由参与者自行报告。采用Kaplan-Meier生存曲线来说明不同社交活动水平中心血管事件的累积发生率。使用Cox比例风险回归模型和受限立方样条（RCS）来评估社交活动与心血管疾病风险之间的关联。进行亚组分析以探索社交活动与心血管疾病风险之间的潜在相互作用，按年龄、性别、教育水平、吸烟和饮酒状况、慢性病数量、抑郁和体重指数（BMI）进行分层。
共有4099名参与者纳入分析。在9年的随访期内，发生了813例心血管事件。在调整年龄、性别、居住地、教育程度、婚姻状况、吸烟和饮酒习惯、慢性病负担、抑郁和BMI后，社交活动水平每降低0.1，心血管事件风险增加7.4%（校正风险比，1.074；95%置信区间：1.069-1.079）。
在中国中老年人群中，社交活动与心血管疾病风险显著相关。这些发现强调了维持社交参与对支持该人群心血管健康的重要性。
