以前的文献表明，社区中健康食品的可用性与区域特征和饮食质量有关。这项研究调查了生活在巴尔的摩市的2,616名参与者的健康食品供应与体重指数（BMI）之间的关系。训练有素的工作人员收集了2004年至2008年期间的人口统计学信息，身高，体重和24小时饮食回忆。2007年，在34个不同种族和社会经济地位组成的人口普查区，使用营养环境措施调查-商店确定了健康食品的供应情况。多水平线性回归用于估计健康食品供应和BMI之间的关联。在人口统计学变量调整后，生活在以白色为主的社区的个体中，与生活在低健康食物可获得性社区的个体相比，健康食物的高可获得性与显著更高的BMI相关（β=3.22，p=0.001）。相关性减弱，但在控制饮食摄入量后仍显着（β=2.81，p=0.012）。与预期相反，在以白色为主的社区中，健康食品的可获得性与较高的BMI之间存在正相关。这一结果可能是由于健康食品供应量低的地区的个人到社区外旅行以获得健康食品。
Previous literature has shown that the availability of healthy food in neighborhoods is associated with area characteristics and dietary quality. This study investigated the association between the availability of healthy foods and body mass index (BMI) among 2,616 participants living in Baltimore City. Trained staff collected demographic information, height, weight and 24-hr dietary recalls between 2004 and 2008. Healthy food availability was determined in 34 census tracts of varying racial and SES composition using the Nutrition Environment Measures Survey- Stores in 2007. Multilevel linear regression was used to estimate associations between healthy food availability and BMI. Among individuals living in predominately white neighborhoods, high availability of healthy foods was associated with significantly higher BMI compared to individuals living in low healthy food availability neighborhoods after adjustment for demographic variables (β=3.22, p=0.001). Associations were attenuated but remained significant after controlling for dietary intake (β=2.81, p=0.012). Contrary to expectations, there was a positive association between the availability of healthy food and higher BMI among individuals living in predominately white neighborhoods. This result could be due to individuals in low healthy food availability areas traveling outside their neighborhood to obtain healthy food.
