Physical activity occurs in 4 domains (leisure, occupational, household, and transportation), but US surveillance often focuses on leisure-time only. We compared estimates of self-reported leisure-time physical activity and estimates of all-domain activity among adults in the National Health and Nutrition Examination Survey for 2011-2016. During the study period, 38.6% met the aerobic physical activity guideline in leisure-time, 58.5% in leisure-time and occupational/household activity, and 63.7% in all domains. Differences within most subgroups when using all domains were similar to differences when using leisure-time activity only, except that we observed no urban/rural differences in the multidomain assessment. Assessment of multiple domains of activity instead of leisure-time-only activity affects prevalence estimates to a greater extent than it affects subgroup differences.
身体活动存在于 4 个领域(休闲、职业、家务和交通),但美国的监测通常仅关注休闲时间的活动。我们比较了 2011-2016 年国家健康和营养检查调查中成年人自我报告的休闲时间身体活动估计值和所有领域活动的估计值。在研究期间,38.6%的人在休闲时间达到了有氧运动活动指南,58.5%的人在休闲时间和职业/家务活动中达到了这一标准,63.7%的人在所有领域都达到了这一标准。在使用所有领域时,大多数亚组内的差异与仅使用休闲时间活动时的差异相似,除了在多领域评估中没有观察到城乡差异。与仅评估休闲时间活动相比,评估多个领域的活动对流行率估计的影响更大,而对亚组差异的影响则较小。
