目的：我们研究是否物理接近超市或超市的价格更强烈地与obesity risk.METHODS：西雅图肥胖研究（SOS）收集和地理编码数据的家庭地址和食品购物目的地的一个代表性的样本，金郡，华盛顿的成年居民。超市被分为3个价格水平的基础上，平均成本的市场篮子。社会人口和健康数据来自电话调查。修正泊松回归被用来测试肥胖和超市变量之间的关联。结果：只有1/7的受访者报告在最近的超市购物。肥胖的风险与家与最近的超市或SOS参与者报告为主要食物来源的超市之间的街道网络距离无关。即使在调整了个人层面的社会人口统计学和生活方式变量以及邻近措施之后，超市的类型（按价格计算）也与肥胖率呈显著负相关（调整后的相对危险度=0.34; 95%可信区间=0.19，0.63）结论：改善超市的物理访问可能是应对肥胖流行病的一种策略;改善健康食品的经济可及性是另一个问题。
OBJECTIVES: We examined whether physical proximity to supermarkets or supermarket price was more strongly associated with obesity risk.METHODS: The Seattle Obesity Study (SOS) collected and geocoded data on home addresses and food shopping destinations for a representative sample of adult residents of King County, Washington. Supermarkets were stratified into 3 price levels based on average cost of the market basket. Sociodemographic and health data were obtained from a telephone survey. Modified Poisson regression was used to test the associations between obesity and supermarket variables.RESULTS: Only 1 in 7 respondents reported shopping at the nearest supermarket. The risk of obesity was not associated with street network distances between home and the nearest supermarket or the supermarket that SOS participants reported as their primary food source. The type of supermarket, by price, was found to be inversely and significantly associated with obesity rates, even after adjusting for individual-level sociodemographic and lifestyle variables, and proximity measures (adjusted relative risk=0.34; 95% confidence interval=0.19, 0.63)CONCLUSIONS: Improving physical access to supermarkets may be one strategy to deal with the obesity epidemic; improving economic access to healthy foods is another.
