Given disproportionate burden of physical inactivity among US Hispanics and emerging interests in the potential role of the built environment on physical activity, we tested the hypothesis that residing in a more walkable block group is associated with increased physical activity in a cohort of Mexican-American adults. 10,183 Mexican-American adults from Houston, TX, USA were studied. Physical activity was assessed through self-report. Geographical information systems were used to create a "walkability index" (WI). We examined the relationship between WI and physical activity using regression models. Findings for the entire study population suggested a direct association between neighborhood walkability and physical activity that approached statistical significance (High WI vs. Low WI: OR = 1.16; 95% CI 0.95-1.40). Furthermore, participants who lived in a higher WI neighborhood were more likely to meet physical activity guidelines in 2 groups: (1) men whose recreational physical activity included walking (High WI vs. Low WI: OR = 5.43; 95% CI 1.30-22.73) and (2) men whose only recreational physical activity was (High WI vs. Low WI: OR = 9.54; 95% CI 1.84-49.60). Our findings suggest gender differences in the association between the built environment and physical activity in Mexican-American adults. Attempts to encourage walking among Mexican-American adults may be easier in high-walkability neighborhoods than in low-walkability neighborhoods.
鉴于美国西班牙裔人群身体活动不足的负担过重，且人们对建成环境在身体活动方面的潜在作用的兴趣日益浓厚，我们检验了这样一个假设：居住在步行便利性更高的街区组与墨西哥裔美国成年人队列中身体活动的增加有关。对来自美国得克萨斯州休斯敦的10183名墨西哥裔美国成年人进行了研究。通过自我报告评估身体活动情况。使用地理信息系统创建了一个“步行便利性指数”（WI）。我们使用回归模型研究了WI与身体活动之间的关系。整个研究人群的结果表明，邻里步行便利性与身体活动之间存在直接关联，接近统计学显著性（高WI与低WI：OR = 1.16；95%CI 0.95 - 1.40）。此外，居住在WI较高社区的参与者在两组中更有可能达到身体活动指南的要求：（1）休闲身体活动包括步行的男性（高WI与低WI：OR = 5.43；95%CI 1.30 - 22.73）和（2）唯一的休闲身体活动是……的男性（高WI与低WI：OR = 9.54；95%CI 1.84 - 49.60）。我们的研究结果表明，在墨西哥裔美国成年人中，建成环境与身体活动之间的关联存在性别差异。在步行便利性高的社区鼓励墨西哥裔美国成年人步行可能比在步行便利性低的社区更容易。
