导言：居住在贫困地区与较低的身体活动率有关。人们对调节这种关系的剥夺的表现知之甚少。本研究旨在探讨是否获得体育活动资源介导邻里社会经济地位和体育活动之间的关系在women.Method：从妇女参加的斯坦福大学心脏病预防计划（1979-90）的个人数据与人口普查和档案数据从现有的记录。多层次回归模型进行了检查的能量消耗和中度和剧烈的体力活动报告在体力活动recalles.Results：后占个人层面的社会经济地位，妇女谁住在较低的社会经济地位的社区报告更大的能量消耗，但进行较少的中度体力活动，比妇女在中等社会经济地位的社区。相比之下，生活在较高社会经济地位社区的妇女报告说，她们的体力活动比生活在中等社会经济地位社区的妇女多。虽然身体活动资源的可用性似乎并没有调解任何邻里社会经济地位协会，出现了几个重要的相互作用，这表明低收入或生活在较低社会经济地位邻里的妇女可能会从更大的身体活动资源可用性中获益。尽管我们发现，在社会经济地位较低的社区居住与女性进行较少的中度或剧烈体育活动之间存在预期关系，我们还发现，这些女性报告的总体能量消耗更大，可能是由于工作或旅行需求增加。附近更多的体育活动资源似乎对生活在社会经济地位较低的社区的妇女和低收入妇女有不同的好处，对决策和规划有影响。
Introduction: Residence in a deprived neighbourhood is associated with lower rates of physical activity. Little is known about the manifestation of deprivation that mediates this relationship. This study aimed to investigate whether access to physical activity resources mediated the relationship between neighbourhood socioeconomic status and physical activity among women.Method: Individual data from women participating in the Stanford Heart Disease Prevention Program (1979-90) were linked to census and archival data from existing records. Multilevel regression models were examined for energy expenditure and moderate and vigorous physical activity as reported in physical activity recalls.Results: After accounting for individual-level socioeconomic status, women who lived in lower-socioeconomic status neighbourhoods reported greater energy expenditure, but undertook less moderate physical activity, than women in moderate-socioeconomic status neighbourhoods. In contrast, women living in higher-socioeconomic status neighbourhoods reported more vigorous physical activity than women in moderate-socioeconomic status neighbourhoods. Although availability of physical activity resources did not appear to mediate any neighbourhood socioeconomic status associations, several significant interactions emerged, suggesting that women with low income or who live in lower-socioeconomic status neighbourhoods may differentially benefit from greater physical activity resource availability.Discussion: Although we found expected relationships between residence in a lower-socioeconomic status neighbourhood and undertaking less moderate or vigorous physical activity among women, we also found that these same women reported greater overall energy expenditure, perhaps as a result of greater work or travel demands. Greater availability of physical activity resources nearby appears to differentially benefit women living in lower-socioeconomic status neighbourhoods and low-income women, having implications for policy-making and planning.
