中文摘要：

本文利用中国高龄老人健康长寿跟踪调查数据（2008年和2011—2012年），基于社会学视阈考察中国大陆轻度认知障碍老人死亡风险的影响因素。应用Cox比例风险模型，在控制入口学特征的前提下，考察肌体健康、生活方式、心理特征、社会经济地位四个方面因素的影响。结果表明，肌体健康因素对轻度认知障碍老人死亡风险影响最大，肌体健康的轻度认知障碍老人的死亡风险比健康状况较差的老人低38％左右。生活方式因素中，适量饮酒和参加锻炼均能显著降低轻度认知障碍老人死亡风险，使其降低13％左右；是否吸烟的影响并不显著。喜欢干净整洁和不感到紧张等积极的心理特征因素对降低认知障碍老人死亡风险具有显著作用，使死亡风险降低12％～22％左右。社会经济地位因素中只有居住在城市对降低轻度认知障碍老人死亡风险有显著作用，而其余因素的影响均不显著。概括而言，良好的肌体健康状况、适量饮酒、经常参加锻炼、积极的心理状态以及居住在城市会显著降低轻度认知障碍老人的死亡风险。

Cox Proportional Hazard Model was used to examine the effects of physical health, lifestyle, psychological feature, and socioeconomic sta- tus under the premise of controlling the demographic characteristics. The results turn out that physical health has the most important influence on mortality risk of elderly with mild cognitive impairment. Elderly who have good physical health have a 38% lower risk of death than those who have poor physical health. Moderate drinking and doing exercise could significantly reduce the mortality of elderly with mild cognitive impairment by decreasing a 13% lower risk of death. The effect of smoking is not significant at all. Elderly who like clearness and didn＇ t feel nervous have a 12 - 22% lower risk of death than other elderly. Among the factors of socioeconomic status, only the factor living in city has significant effect.
