BACKGROUND
Although improvements in life expectancy have been attributed in part to the adoption of a more prudent lifestyle, few studies have examined the association of lifestyle with survival, using several lifestyle factors simultaneously, in a healthy elderly population.
METHODS
We investigated the association of health related behaviors with mortality in 7989 men aged 65 to 83 years participating in a population-based trial in Perth, Western Australia, by calculating a lifestyle score as a simple tally of how many of eight prudent behaviors each individual followed.
RESULTS
Invitations to screening produced a corrected response of 70.5%. Out of a possible score of 8, 46% of men had a score of less than 5. Within 5 years, a total of 703 men (9%) had died from any cause. The hazard ratio in men with a low lifestyle score was 1.3 [95% confidence interval (CI): 1.1-1.5] compared with men with a score of 5 or more.
CONCLUSIONS
Lifestyle remains an important predictor of mortality even in old age. Survival in older men without a history of cardiovascular disease can potentially be enhanced by promoting a healthy lifestyle.
背景
尽管预期寿命的提高部分归因于采用了更谨慎的生活方式，但很少有研究在健康老年人群中同时使用多种生活方式因素来研究生活方式与生存之间的关联。
方法
我们通过计算生活方式得分（即每个个体遵循的八项谨慎行为中有多少项的简单计数），调查了参与西澳大利亚珀斯一项基于人群试验的7989名65至83岁男性中与健康相关行为与死亡率之间的关联。
结果
筛查邀请的校正回复率为70.5%。在可能的8分中，46%的男性得分低于5分。在5年内，共有703名男性（9%）死于任何原因。生活方式得分低的男性与得分5分或更高的男性相比，风险比为1.3[95%置信区间（CI）：1.1-1.5]。
结论
即使在老年，生活方式仍然是死亡率的重要预测因素。通过促进健康的生活方式，有可能提高无心血管疾病史老年男性的生存率。
