英文文献摘要：
We examine the effect of proximity to large grocery stores and convenience stores on consumption of different food groups among a sample of children enrolled in Head Start preschools. Food store proximity is measured in two ways: (1) as the distance from the census block of residence to the nearest store of a given type and (2) as the density of stores within a one-mile radius of the census block. We estimate the probability that a child is at risk for over or under consumption of a given food item. Food-store proximity is instrumented using the proportion of commercially zoned land surrounding the residence. Findings suggest that children in households with greater access to large grocery stores are at less risk for under consumption of healthy foods but are also at greater risk for over consumption of sugary beverages.

食品店邻近度的衡量方法有两种:(1)作为人口普查居住地到最近的给定类型食品店的距离;(2)作为人口普查街区半径一英里内的食品店密度。我们估计了儿童因食用某一特定食物过多或过少而面临风险的概率。利用住宅周围商业用地的比例来衡量食品店的邻近程度。研究结果表明，家庭中有较多机会进入大型杂货店的儿童，健康食品摄入不足的风险较低，但含糖饮料摄入过量的风险也较高。
