Abstract：
UNASSIGNED: Previous studies have shown social activity is associated with reduced risk of health outcomes. However, among older people (≥65 years) who were socially inactive at baseline, limited study explored whether increased participation in social activity in later life was associated with reduced risk of health outcomes; therefore, using the data from the Chinese Longitudinal Healthy Longevity Survey, the study was performed.
UNASSIGNED: The study outcomes were 10-year all-cause mortality (sample number = 9,984) and 10-year heart diseases (sample number = 7,496). The exposure was the change of social activity frequency. Cox regression analysis was used for data analysis.
UNASSIGNED: During the follow-up, there were 6,407 all-cause mortalities and 1,035 heart diseases, respectively. Kaplan-Meier analysis demonstrated that cumulative incidences of all-cause mortality were significantly lower in participants with changes into more frequent social activity (log-rank p < 0.001), while no significant difference was observed for heart diseases (log-rank p = 0.330). Compared with the subgroup who never participated in social activity at baseline, adjusted HRs of all-cause mortality were 0.79 (95% CI: 0.70-0.90, p < 0.001), 0.78 (95% CI: 0.63-0.96, p = 0.019), 0.74 (0.59-0.92, p = 0.006), and 0.70 (95% CI: 0.56-0.88, p = 0.002) for the subgroup of switching to sometimes, the subgroup of switching to once a month, the subgroup of switching to once a week, and the subgroup of switching to everyday, respectively. The corresponding HRs of heart diseases were 0.83 (95% CI: 0.65-1.08, p = 0.170), 0.82 (95% CI: 0.51-1.31, p = 0.412), 0.91 (0.58-1.42, p = 0.675) and 0.75 (95% CI: 0.47-1.20, p = 0.227), respectively. Stratified and sensitivity analyses revealed similar results.

摘要：
■先前的研究表明，社交活动与健康结果的风险降低有关。然而,在基线时不从事社交活动的老年人（≥65岁）中，有限的研究探讨了在以后的生活中增加参与社会活动是否与健康结果的风险降低相关;因此,使用中国纵向健康长寿调查的数据，进行了这项研究。
■研究结果是10年全因死亡率（样本数=9,984）和10年心脏病（样本数=7,496）。暴露是社会活动频率的变化。采用Cox回归分析进行数据分析。
■在随访期间，全因死亡率6407例,心脏病1035例,分别。Kaplan-Meier分析表明，随着社会活动的频繁变化，参与者的全因死亡率累积发生率显着降低（log-rankp<0.001）。而心脏疾病没有观察到显著差异(log-rankp=0.330)。与基线时从未参加过社交活动的亚组相比，全因死亡率的校正HR为0.79(95%CI:0.70-0.90,p<0.001),0.78（95%CI：0.63-0.96，p=0.019），0.74（0.59-0.92，p=0.006），和0.70(95%CI：0.56-0.88，p=0.002)的亚组切换到有时，每月切换一次的子组，每周切换一次的子组，以及切换到日常的子群，分别。心脏病的相应HR为0.83（95％CI：0.65-1.08，p=0.170），0.82（95%CI：0.51-1.31，p=0.412），0.91（0.58-1.42，p=0.675）和0.75（95%CI：0.47-1.20，p=0.227），分别。分层和敏感性分析显示出类似的结果。
■在从未参加过社交活动的老年人中，在以后的生活中参与社会活动的增加与全因死亡的风险降低有关，但与心脏病风险降低无关。
