To explore the relationship between successful aging (SA) index and the survival status among elderly from longevity areas of China. A total of 2 296 old people aged ≥65 years old from 8 longevity areas were enrolled in our baseline survey in 2012. The information of demographics characteristic, life style, self-assessed health and mood or emotional state, cognitive function, abilities of daily living and physical activity were collected by questionnaire. There were 891 SA people in total, whose SA score was 4-5. 891 SA and 1 396 non-SA participated in the follow-up study in 2014. Finally, 860 SA and non-SA people were matched by orientation analysis. A Cox proportional hazards model was used to explore the relationship between successful aging index and survival status. After 2 years of follow-up, a total of 1 442 elderly survived, with an average baseline age at (83.69±10.81) years old and 278 elderly people died, with an average baseline age at (93.41±9.05) years old. The mortality rate was 16.16% (278/1 720) in total, and it was 13.14% (113/860) in SA group, which was lower than it in non-SA group (19.19%, 165/860), and the difference was statistically significant (=0.001). The analysis of the multivariate Cox regression showed that SA was the protective factor of the survival of the elderly after age and sex adjusted. Compared to the non-SA group, the risk of mortality rate in SA group decreased by 38%, the (95% ) was 0.62 (0.49-0.79). The mortality rate in the SA group was low in the longevity areas in China; compared with non-SA group, the death rate in SA group reduced by 38%.
探索中国长寿地区老年人成功老龄化（SA）指数与生存状况之间的关系。2012年，我们对来自8个长寿地区的2296名年龄≥65岁的老年人进行了基线调查。通过问卷调查收集了人口统计学特征、生活方式、自我评估的健康状况和情绪状态、认知功能、日常生活能力和身体活动等信息。共有891名SA人群，其SA得分为4 - 5分。891名SA人群和1396名非SA人群于2014年参与了随访研究。最后，通过倾向性分析匹配了860名SA和非SA人群。采用Cox比例风险模型探讨成功老龄化指数与生存状况之间的关系。经过2年的随访，共有1442名老年人存活，平均基线年龄为（83.69±10.81）岁，278名老年人死亡，平均基线年龄为（93.41±9.05）岁。总死亡率为16.16%（278/1720），SA组为13.14%（113/860），低于非SA组（19.19%，165/860）,差异有统计学意义（P = 0.001）。多因素Cox回归分析显示，在调整年龄和性别后，SA是老年人生存的保护因素。与非SA组相比，SA组死亡率风险降低了38%，风险比（95%置信区间）为0.62（0.49 - 0.79）。中国长寿地区SA组的死亡率较低；与非SA组相比，SA组死亡率降低了38%。
