Physical activity for any purpose counts toward meeting Physical Activity Guidelines (PAG). However, national surveillance systems traditionally focus on leisure-time physical activity. There is an incomplete understanding of the association between meeting PAG in leisure time and occupation activity level among US workers.
We used cross-sectional 2020 National Health Interview Survey data to examine US adults aged 18-64 years who worked the week before the survey (n = 14,814). We estimated the proportion meeting aerobic and muscle-strengthening PAG in leisure time by occupation activity level (low, intermediate, and high). Using logistic regression, we examined the association between meeting PAG in leisure time and occupation activity level, adjusted for sociodemographic characteristics and stratified by hours worked. We compared the sociodemographic characteristics of adults working ≥40 hours (the previous week) in high-activity occupations to those in low- or intermediate-activity occupations.
Adults working in high-activity occupations were less likely to meet PAG in leisure time (26.1% [24.3-28.1]) versus those in low-activity (30.6% [29.1-32.2], P < .01) or intermediate-activity (32.4% [30.8-34.2]) occupations. In stratified, adjusted models, adults working ≥40 hours in low- and intermediate-activity occupations were 13% and 20%, respectively, more likely to meet PAG in leisure time versus those in high-activity occupations. Among those working ≥40 hours, adults in high-activity occupations were more likely to be Hispanic or Latino, male, younger, and have a high school education or lower compared with those in less active occupations.
Traditional surveillance may underestimate meeting PAG among people working in high-activity occupations, potentially disproportionately affecting certain groups.
任何目的的身体活动都有助于达到身体活动指南（PAG）的要求。然而，传统的国家监测系统通常侧重于休闲时间的身体活动。对于美国工人在休闲时间达到 PAG 与职业活动水平之间的关联，我们的理解并不完整。
我们使用 2020 年全国健康访谈调查的横断面数据，调查了在调查前一周工作的 18-64 岁美国成年人（n=14814）。我们根据职业活动水平（低、中、高）估计了在休闲时间达到有氧和肌肉强化 PAG 的比例。使用逻辑回归，我们调整了社会人口统计学特征并按工作小时数进行分层后，检查了在休闲时间达到 PAG 与职业活动水平之间的关联。我们比较了每周工作≥40 小时（前一周）的高活动职业的成年人与低或中活动职业的成年人的社会人口统计学特征。
从事高活动职业的成年人在休闲时间达到 PAG 的可能性较低（26.1%[24.3-28.1]），而从事低活动（30.6%[29.1-32.2]，P<0.01）或中活动（32.4%[30.8-34.2]）职业的成年人。在分层调整后的模型中，每周工作≥40 小时的低活动和中活动职业的成年人分别有 13%和 20%更有可能在休闲时间达到 PAG，而不是从事高活动职业的成年人。在每周工作≥40 小时的成年人中，与从事低活动职业的成年人相比，从事高活动职业的成年人更有可能是西班牙裔或拉丁裔、男性、年轻、且受教育程度较低。
传统监测可能低估了从事高活动职业的人群达到 PAG 的比例，这可能会不成比例地影响某些群体。
