使用食物环境和模型规格的替代测量方法，检验邻里食物环境与青少年体重指数(BMI)百分位数之间关系的稳健性。观察性研究使用了对五年级和八年级儿童的个人层面纵向调查数据，并结合了基于学生居住普查区域的食品销售点数据。食物环境和BMI之间的关系通过两个单独的结果(八年级的BMI百分位数和从五年级到八年级的BMI百分位数的变化)和三个可选的食物环境衡量标准(特定食品店类型的人均计数、食品环境指数和特定食品店类型组合的指标)来检验。在衡量标准(每人口特定类型的食品销售点的计数、食品环境指数和存在特定类型的食品商店组合的指标)和结果上没有发现一致的证据来支持这样的假设，即更容易进入大型超市会导致较低的青年BMI；或者更多地接触快餐店、便利店和小型食品店会增加BMI。在一定程度上，食物环境与青少年BMI之间存在关联，一个地区存在更多类型的食品店，包括超市，与更高的BMI相关。
To examine the robustness of the relationship between neighbourhood food environment and youth body mass index (BMI) percentile using alternative measures of food environment and model specifications. Observational study using individual-level longitudinal survey data of children in fifth and eighth grades merged with food outlet data based on student residential census tracts. The relationship between food environment and BMI was examined with two individual outcomes (BMI percentile in eighth grade and change in BMI percentile from fifth to eighth grade) and three alternative measures of food environment (per-capita counts of a particular outlet type, food environment indices, and indicators for specific combinations of outlet types). No consistent evidence was found across measures (counts of a particular type of food outlet per population, food environment indices, and indicators for the presence of specific combinations of types of food stores) and outcomes to support the hypothesis that improved access to large supermarkets results in lower youth BMI; or that greater exposure to fast food restaurants, convenience stores and small food stores increases BMI. To the extent that there is an association between food environment and youth BMI, the existence of more types of food outlets in an area, including supermarkets, is associated with higher BMI.
