背景：贫困社区的居民有较高的身体质量指数（BMI），吃得不健康。一个可能的原因可能是他们所在地区现有食物的质量。杂货店的位置，个人购物及其与BMI.Methods的关联进行了检查：2000年美国人口普查数据与洛杉矶家庭和邻里研究（洛杉矶FANS）数据库，其中包括2620名成年人从65个街区在洛杉矶县2000年和2002年之间抽样。在2005年，多层次线性回归被用来估计BMI和社会经济特征的杂货店位置调整后的个人水平的因素和社会经济特征的住宅neighborhoods.Results：个人有较高的BMI，如果他们居住在贫困地区，并在该地区的平均人经常光顾杂货店位于更贫困的社区之间的关联。那些拥有汽车和前往杂货店更远的人也有更高的BMI。当控制杂货店人口普查区的社会经济地位（SES），住宅人口普查区SES和BMI之间的关联变得strengthen.Conclusions：人们在哪里买杂货和前往杂货店的距离与BMI独立相关。接触杂货店调解和抑制居民区与BMI的关联，并可以解释为什么以前的研究可能没有发现居民区预测因子与BMI之间的强关联。
Background: Residents in poor neighborhoods have higher body mass index (BMI) and eat less healthfully. One possible reason might be the quality of available foods in their area. Location of grocery stores where individuals shop and its association with BMI were examined.Methods: The 2000 U.S. Census data were linked with the Los Angeles Family and Neighborhood Study (L.A.FANS) database, which consists of 2620 adults sampled from 65 neighborhoods in Los Angeles County between 2000 and 2002. In 2005, multilevel linear regressions were used to estimate the associations between BMI and socioeconomic characteristics of grocery store locations after adjustment for individual-level factors and socioeconomic characteristics of residential neighborhoods.Results: Individuals have higher BMI if they reside in disadvantaged areas and in areas where the average person frequents grocery stores located in more disadvantaged neighborhoods. Those who own cars and travel farther to their grocery stores also have higher BMI. When controlling for grocery store census tract socioeconomic status (SES), the association between residential census tract SES and BMI becomes stronger.Conclusions: Where people shop for groceries and distance traveled to grocery stores are independently associated with BMI. Exposure to grocery store mediates and suppresses the association of residential neighborhoods with BMI and could explain why previous studies may not have found robust associations between residential neighborhood predictors and BMI.
