Evaluating lifestyle factors associated with mortality in the elderly

我们通过分析30，000名年龄在65岁或以上的受试者的数据，评估了生活方式因素与老年人死亡率之间的关联，这些受试者参加了一项大规模队列研究。与中年受试者一样，拥有健康的生活方式（不吸烟或大量饮酒等）降低死亡风险，即使是老年人。在60岁时，与最不健康的人相比，生活方式最健康的人的男性预期寿命增加了9.6年，女性预期寿命增加了8.2年。然而，与中年受试者不同，我们发现不是肥胖而是较低的BMI增加了死亡风险。此外，与中年人相比，老年人中社会角色较少的人（如配偶，父母和工人）的风险值较低。

We evaluated the association between lifestyle factors and mortality in the elderly by analyzing the data of 30,000 subjects aged 65 years or older, enrolled in a large scale cohort study. As with middle-aged subjects, having a healthy lifestyle (not smoking or drinking heavily etc.) reduced mortality risk, even among the elderly. At the age of 60, a 9.6-year increase in life expectancy for men and an 8.2-year increase for women was found for those with the most healthy lifestyles compared to those with the least healthy. However, unlike with middle-aged subjects, we found that not obesity but a lower BMI increased mortality risk. Furthermore, risk values of those with fewer social roles (such as spouse, parent, and worker) were lower among elderly subjects compared with the middle-aged.
