Although discrimination has been identified as a potential determinant of existing racial/ethnic health disparities, no studies have investigated whether racial discrimination contributes to disparities in physical activity.
The primary aim of the current study was to examine the association between interpersonal racial discrimination and physical activity.
Baseline data were collected during 2004-2005 among a predominately black and Hispanic sample of adult residents living in 12 low-income-housing sites in Boston MA (n=1055). Residents reported experiences of lifetime racial discrimination during interviewer-administered surveys and wore a pedometer for 5 days to measure physical activity. For analyses, performed in 2009, linear regression models with a cluster design were conducted to predict physical activity, measured as steps per day.
Nearly 48% of participants reported ever experiencing racial discrimination, and discrimination was most commonly experienced on the street or in a public setting. No association was found between discrimination and physical activity, when examined in bivariate, multivariable, or race-stratified models.
The current results indicate that self-reported racial discrimination is not a key determinant of physical activity among residents living in low-income housing. However, additional research is warranted to address current limitations of this study.
尽管歧视已被确定为造成现有种族/民族健康差异的一个潜在决定因素，但尚无研究调查种族歧视是否导致体力活动方面的差异。
本研究的主要目的是检验人际种族歧视与体力活动之间的关系。
2004-2005 年期间，在马萨诸塞州波士顿的 12 个低收入住房点居住的以黑人和西班牙裔为主的成年居民中收集了基线数据（n=1055）。居民在接受采访者管理的调查时报告了一生中经历种族歧视的情况，并佩戴计步器 5 天以测量体力活动。在 2009 年进行的分析中，采用具有聚类设计的线性回归模型预测体力活动，以每天的步数衡量。
近 48%的参与者报告曾经历过种族歧视，歧视最常发生在街头或公共场所。在单变量、多变量或按种族分层的模型中，歧视与体力活动之间均无关联。
目前的结果表明，报告的种族歧视并不是居住在低收入住房中的居民体力活动的主要决定因素。但是，需要开展更多的研究来解决本研究的当前局限性。
