邻里食物环境的差异可能会导致肥胖的差异。本研究的目的是在控制邻里步行性后，研究邻里饮食环境与体重指数（BMI）和肥胖的关系。本研究采用横断面多水平分析方法，对纽约市13,102名成年居民的BMI和肥胖进行了研究。我们构建的措施，食品环境和步行的邻里，定义为一个半英里的缓冲区周围的研究对象的家庭地址。BMI健康食品店（超市、果蔬市场和天然食品店）的密度与BMI呈负相关。健康食品密度的前两个五分位数（分别为0和1.13家商店/平方公里）的平均调整后BMI相似，但在三个较高的五分位数中下降，第五个五分位数（10.98家商店/平方公里）比第一个五分位数低0.80个单位[95%置信区间（CI），0.27-1.32]。将健康食物密度的五分之五与最低的两个五分之一相比较，肥胖患病率为0.87（95% CI，0.78-0.97）。这些协会仍然控制后，两个邻里步行的措施，人口密度和土地利用组合。人口密度第四与第一四分位数的肥胖患病率为0.84（95%CI，0.73-0.96），土地使用混合为0.91（95%CI，0.86-0.97）。被归类为BMI不健康的食品店密度的增加与BMI或肥胖无关。进入BMI健康食品商店与较低的BMI和较低的肥胖患病率有关。
Differences in the neighborhood food environment may contribute to disparities in obesity. The purpose of this study was to examine the association of neighborhood food environments with body mass index (BMI) and obesity after control for neighborhood walkability. This study employed a cross-sectional, multilevel analysis of BMI and obesity among 13,102 adult residents of New York City. We constructed measures of the food environment and walkability for the neighborhood, defined as a half-mile buffer around the study subject’s home address. Density of BMI-healthy food outlets (supermarkets, fruit and vegetable markets, and natural food stores) was inversely associated with BMI. Mean adjusted BMI was similar in the first two quintiles of healthy food density (0 and 1.13 stores/km2, respectively), but declined across the three higher quintiles and was 0.80 units lower [95% confidence interval (CI), 0.27–1.32] in the fifth quintile (10.98 stores/km2) than in the first. The prevalence ratio for obesity comparing the fifth quintile of healthy food density with the lowest two quintiles combined was 0.87 (95% CI, 0.78–0.97). These associations remained after control for two neighborhood walkability measures, population density and land-use mix. The prevalence ratio for obesity for the fourth versus first quartile of population density was 0.84 (95% CI, 0.73–0.96) and for land-use mix was 0.91 (95% CI, 0.86–0.97). Increasing density of food outlets categorized as BMI-unhealthy was not significantly associated with BMI or obesity. Access to BMI-healthy food stores is associated with lower BMI and lower prevalence of obesity.
