这篇论文使用了三个领先的全国性调查(NHANES、BRFSS和NHIS)的数据，调查了有多少老年人(65岁以上)达到了体力活动(PA)指南(PAG；150分钟/周的中等到剧烈的体力活动)。在每个调查的最近可用周期中，确定了达到需氧PAG的个体比例(NHANES 2011-12，NHIS和BRFSS 2013)。我们还评估了PAG的遵守情况是否随着时间的推移而发生了变化。多项Logistic回归的预测边际是在调整了年龄、种族/民族、性别和样本重量后计算出来的。符合PAG的老年人比例NHANES为27.3%，NHIS为35.8%，BRFSS为44.3%。在所有调查中，男性报告的活动水平高于女性，非西班牙裔白人报告的活动水平高于非西班牙裔黑人和西班牙裔，活动水平随着年龄的增长而下降，有功能障碍的人的活动水平更低，均为P<；0.05。在NHIS调查中，达到PAG的老年人比例从1998年的25.7%上升到2013年的35.8%(P<；0.01)。NHIS调查是唯一一项PA问题随时间保持不变的调查。对活动水平的点数估计在不同的调查中有所不同，但它们一致地确定了不太活跃的子组。尽管随着时间的推移，老年人报告的运动量增加，但有氧和力量训练的坚持程度在这一人群中仍然很低，需要进行有效的干预，以防止与年龄相关的PA下降，并解决老年人中的健康差距。
This paper examined how many older adults (65+ yrs) are meeting physical activity (PA) Guidelines (PAG; 150 min/wk of moderate-to-vigorous PA) using data from three leading national surveys (NHANES, BRFSS and NHIS). The proportion of individuals meeting aerobic PAG was determined for the most recent cycle available for each survey (NHANES 2011–12, NHIS and BRFSS 2013). We also assessed whether PAG adherence has changed over time. Predicted margins from multinomial logistic regression were computed after adjusting for age, race/ethnicity and gender and sample weights. The proportion of older adults meeting PAG was 27.3% for NHANES, 35.8% for NHIS and 44.3% for BRFSS. Across all surveys, men reported higher levels of activity than women, Non-Hispanic Whites reported higher levels than Non-Hispanic Blacks and Hispanics, activity declined with age and was lower in those with functional limitations, all P<0.05. The proportion of older adults meeting PAG in the NHIS survey, the only survey where PA questions remained the same over time, increased from 25.7% in 1998 to 35.8% in 2013 (P<0.01). Point-estimates for activity levels are different between surveys but they consistently identify sub-groups who are less active. Although older adults are reporting more activity over time, adherence to aerobic and strength training PAG remains low in this population and there is a need for effective interventions are needed to prevent age-related declines in PA and address health disparities among older adults.
