DESCRIPTION (provided by applicant): This project will investigate racial and ethnic differences in physical activity (PA). This is important since PA has been shown to have a positive impact on health. Physical activity occurs during leisure-time, household work and market work. Prior studies show that whites engage in more leisure time PA than minorities. However, there is evidence that minorities engage in more PA at work. Less is known about PA differentials in household work and about total PA differentials. Prior studies of PA have relied largely on small esoteric samples or on one of three national datasets. These small samples are problematic since they cannot be generalized to the overall population. The national data sets are also problematic since they include reporting and recall errors, lack detailed information on the various types of PA and measure PA in relation to subjective categories which are open to individual interpretation. This project will improve on prior studies by employing the American Time Use Survey (ATUS) for a comprehensive examination of racial and ethnic differences in PA and an examination of the correlates of PA for specific race and ethnic subgroups. The ATUS is a large nationally-representative sample which includes extensive data on PA. These surveys include a detailed time diary and have undergone substantive field testing, and follow-up testing to ensure consistency. Multivariate analyses will investigate whether, and to what extent, the observed differences in the various types of PA are driven by differences in income and education, other demographics, environmental factors, occupation and industry selection, and other measures of individual heterogeneity. These estimates will be policy relevant since they will be useful in identifying public policies to promote PA within target groups. If there is significant variation in PA across race/ethnic groups, then these differences may also be contributing to the persistent racial disparities in health status, for which the underlying causes are not fully accounted. PUBLIC HEALTH RELEVANCE: This project will measure differences in physical activity by race and ethnic group. The factors contributing to any differentials will also be investigated. Since physical activity has been shown to have a positive effect on health, lower levels for minority groups would be a factor contributing to observed racial and ethnic health differentials.

描述（由申请人提供）：该项目将调查体育活动（PA）方面的种族和民族差异。这一点很重要，因为 PA 已被证明对健康有积极影响。体力活动发生在闲暇时间、家务劳动和市场工作中。先前的研究表明，白人比少数族裔参与更多的休闲时间私人活动。然而，有证据表明少数族裔在工作中参与更多的体能活动。人们对家务劳动中的 PA 差异和总 PA 差异知之甚少。先前对 PA 的研究主要依赖于小型深奥样本或三个国家数据集之一。这些小样本是有问题的，因为它们不能推广到总体。国家数据集也存在问题，因为它们包括报告和召回错误，缺乏有关各种类型的 PA 的详细信息，也缺乏与个人解释开放的主观类别相关的 PA 测量。该项目将通过采用美国时间利用调查（ATUS）对 PA 的种族和民族差异进行全面检查，并检查特定种族和民族亚群体的 PA 相关性，从而改进先前的研究。 ATUS 是一个具有全国代表性的大型样本，其中包含有关 PA 的大量数据。这些调查包括详细的时间日记，并经过实质性的现场测试，并进行后续测试以确保一致性。多变量分析将调查不同类型 PA 中观察到的差异是否以及在多大程度上是由收入和教育、其他人口统计、环境因素、职业和行业选择以及其他个体异质性衡量标准的差异驱动的。这些估计将与政策相关，因为它们将有助于确定在目标群体内促进巴勒斯坦权力机构的公共政策。如果不同种族/族裔群体的 PA 存在显着差异，那么这些差异也可能导致健康状况方面持续存在的种族差异，而其根本原因尚未得到充分解释。公共卫生相关性：该项目将衡量不同种族和族裔群体身体活动的差异。还将调查造成差异的因素。由于身体活动已被证明对健康有积极影响，少数群体的身体活动水平较低可能是造成种族和民族健康差异的一个因素。
