目前的身体活动指南建议成年人每周参加至少150分钟的中等强度的有氧身体活动，以获得实质性的健康益处。我们使用美国成年人的全国代表性数据样本来估计归因于不足以满足有氧指南的身体活动水平的死亡百分比。方法1990年至1991年针对25岁或以上成年人的全国健康访谈调查的数据与截至2011年12月31日的全国死亡指数的死亡率数据相关联。（N = 67，762人，18，796人死亡）。充分调整后的考克斯比例风险模型的结果被用来估计危险比和人口归因分数不足的体力活动水平（即，每周不到150分钟的中等强度的有氧活动）。ResultsOverall，8.3%（95%置信区间[CI]，6.4-10.2）的死亡归因于体力活动水平不足。对于25至39岁的成年人来说，（-0.2%; 95% CI，-8.8%至7.7%），但在40至69岁的成人中具有显著性（9.9%; 95%CI，7.2%-12.6%）和70岁或以上的成年人（7.8%; 95%CI，4.9%-10.7%）。增加成年人的体育活动水平以满足当前的指导方针可能是降低美国过早死亡风险的一种方法。
IntroductionCurrent physical activity guidelines recommend that adults participate weekly in at least 150 minutes of moderate-intensity equivalent aerobic physical activity to achieve substantial health benefits. We used a nationally representative sample of data of US adults to estimate the percentage of deaths attributable to levels of physical activity that were inadequate to meet the aerobic guideline.MethodsData from the 1990 to 1991 National Health Interview Survey for adults aged 25 years or older were linked with mortality data up until December 31, 2011, from the National Death Index (N = 67,762 persons and 18,796 deaths). Results from fully adjusted Cox proportional hazards models were used to estimate hazard ratios and population attributable fractions for inadequate levels of physical activity (ie, less than 150 minutes per week of moderate-intensity equivalent aerobic activity).ResultsOverall, 8.3% (95% confidence interval [CI], 6.4-10.2) of deaths were attributed to inadequate levels of physical activity. The percentage of deaths attributed to inadequate levels was not significant for adults aged 25 to 39 years (-0.2%; 95% CI, -8.8% to 7.7%) but was significant for adults aged 40 to 69 years (9.9%; 95% CI, 7.2%-12.6%) and adults aged 70 years or older (7.8%; 95% CI, 4.9%-10.7%).ConclusionsA significant portion of deaths was attributed to inadequate levels of physical activity. Increasing adults' physical activity levels to meet current guidelines is likely one way to reduce the risk of premature death in the United States.
