健康生活方式可延长无重大慢性病的预期寿命

本期文章:《英国医学杂志》:Online/在线发表

美国哈佛公共卫生学院Frank B Hu团队分析了健康的生活方式和没有癌症、心血管疾病和2型糖尿病的预期寿命之间的关系。相关论文2020年1月8日发表于《英国医学杂志》。

为了探讨健康生活方式与没有重大慢性疾病的预期寿命之间的关系,研究组进行了一项前瞻性队列研究,参与者包括1980-2014年间护士健康研究中的73196人和1986-2014年间健康专家随访研究的38366人。

五个健康生活方式因素包括从不吸烟、体重指数控制在18.5-24.9、中等强度体力活动(每日超过30分钟)、中等酒精摄入(女性每日5-15g,男性每日5-30g)和较高的饮食质量分数(40%以上)。

不采用健康生活方式的50岁女性没有糖尿病、心血管疾病和癌症等重大慢性疾病的预期寿命为23.7年,而采用健康生活方式的女性无重大慢性病的预期寿命为34.4年。不采用健康生活方式的50岁男性无重大慢性病的预期寿命为23.5年,而采用4-5种健康生活方式因素的男性无重大慢性病的预期寿命为31.1年。目前,大量吸烟(每天超过15支)的男性和肥胖男女(体重指数超过30)在50岁时的无重大慢性病的预期寿命最短,不到平均预期寿命的75%。

总之,中年人坚持健康的生活方式,可延长无重大慢性病的预期寿命。

Abstract: 

Objective To examine how a healthy lifestyle is related to life expectancy that is free from major chronic diseases.

Design Prospective cohort study.

Setting and participants The Nurses’ Health Study (1980-2014; n=73 196) and the Health Professionals Follow-Up Study (1986-2014; n=38 366).

Main exposures Five low risk lifestyle factors: never smoking, body mass index 18.5-24.9, moderate to vigorous physical activity (≥30 minutes/day), moderate alcohol intake (women: 5-15 g/day; men 5-30 g/day), and a higher diet quality score (upper 40%).

Main outcome Life expectancy free of diabetes, cardiovascular diseases, and cancer.

Results The life expectancy free of diabetes, cardiovascular diseases, and cancer at age 50 was 23.7 years (95% confidence interval 22.6 to 24.7) for women who adopted no low risk lifestyle factors, in contrast to 34.4 years (33.1 to 35.5) for women who adopted four or five low risk factors. At age 50, the life expectancy free of any of these chronic diseases was 23.5 (22.3 to 24.7) years among men who adopted no low risk lifestyle factors and 31.1 (29.5 to 32.5) years in men who adopted four or five low risk lifestyle factors. For current male smokers who smoked heavily (≥15 cigarettes/day) or obese men and women (body mass index ≥30), their disease-free life expectancies accounted for the lowest proportion (≤75%) of total life expectancy at age 50.

Conclusion Adherence to a healthy lifestyle at mid-life is associated with a longer life expectancy free of major chronic diseases.
