Latinos in the U.S. bear a disproportionate burden of cardiovascular risk factors, including physical inactivity. Previous research among Latinos has focused on leisure-time physical activity, limiting understanding of the different ways in which populations, particularly working-class groups, achieve recommended levels of physical activity. This study examined associations of race/ethnicity; nativity; and leisure-time, transportation, and occupation-related physical activity among Latino and non-Latino white adults.
Participants sampled in the 2007-2012 waves of the National Health and Nutrition Examination Survey self-reported domain-specific physical activity. Data were analyzed in 2016-2017 using multivariable log binomial regression models to examine differences in meeting guidelines for each physical activity domain separately and as total physical activity among Latinos (n=4,692) and non-Latino whites (n=7,788). Models were adjusted for sociodemographic characteristics and health status and tested interactions between nativity and occupational categories.
In adjusted models, foreign-born Latinos (prevalence ratio=0.70, 95% CI=0.63, 0.77) and U.S.-born Latinos (prevalence ratio=0.85, 95% CI=0.76, 0.95) were least likely to meet physical activity guidelines through occupation-related and leisure time physical activity, when compared with non-Latino whites. By contrast, foreign-born Latinos were more likely to meet physical activity guidelines through transportation physical activity than non-Latino whites (prevalence ratio=1.26, 95% CI=1.01, 1.56) and were proportionately more likely to participate in vigorous modes of physical activity. Interaction results indicated that foreign-born Latinos were the least likely to meet physical activity guidelines compared with U.S.-born Latinos and non-Latino whites if they worked in non-manual occupational categories. All racial/ethnic groups working in manual occupations saw the largest increase (40%-50%) in meeting physical activity guidelines when occupation-related physical activity was combined with leisure-time and transportation physical activity.
These findings suggest variability in the relationship between nativity and the physical activity domain Latinos engage in compared with non-Latino whites, with occupation contributing substantially to meeting physical activity recommendations for all population groups.
在美国，拉丁裔人群承担着不成比例的心血管风险因素负担，包括缺乏身体活动。先前针对拉丁裔人群的研究主要集中在休闲时间的身体活动上，这限制了对不同人群（尤其是工人阶级群体）达到推荐身体活动水平的方式的理解。本研究考察了种族/民族、出生地以及拉丁裔和非拉丁裔白人群体的休闲时间、交通和职业相关身体活动之间的关联。
在 2007-2012 年全国健康和营养调查的波次中，参与者自我报告了特定领域的身体活动情况。2016-2017 年，使用多变量对数二项式回归模型对数据进行分析，以分别检查拉丁裔（n=4692）和非拉丁裔白人（n=7788）在每个身体活动领域和总身体活动中达到指南标准的差异。模型调整了社会人口统计学特征和健康状况，并测试了出生地和职业类别之间的交互作用。
在调整后的模型中，与非拉丁裔白人相比，外国出生的拉丁裔（优势比=0.70，95%置信区间=0.63，0.77）和美国出生的拉丁裔（优势比=0.85，95%置信区间=0.76，0.95）最不可能通过职业相关和休闲时间身体活动达到身体活动指南标准。相比之下，外国出生的拉丁裔比非拉丁裔白人更有可能通过交通身体活动达到身体活动指南标准（优势比=1.26，95%置信区间=1.01，1.56），并且更有可能参与剧烈运动模式的身体活动。交互作用结果表明，如果从事非体力劳动职业类别，与美国出生的拉丁裔和非拉丁裔白人相比，外国出生的拉丁裔最不可能达到身体活动指南标准。从事体力劳动职业的所有种族/民族群体，当将职业相关身体活动与休闲时间和交通身体活动相结合时，达到身体活动指南标准的比例增加了 40%-50%。
这些发现表明，与非拉丁裔白人相比，拉丁裔人在与身体活动领域相关的出生地关系方面存在差异，职业活动对所有人群达到身体活动建议标准有很大贡献。
