The objective of this study is to examine associations of proximity to food establishments with body mass index (BMI) among preschool-age children.
We used baseline data from 438 children ages 2-6.9 years with a BMI ≥ 85th percentile participating in a RCT in Massachusetts from 2006 to 2009. We used a geographic information system to determine proximity to six types of food establishments: 1) convenience stores, 2) bakeries, coffee shops, candy stores, 3) full service restaurants, 4) large supermarkets, 5) small supermarkets, and 6) fast-food restaurants. The main outcome was child's BMI.
Children's mean (SD) BMI was 19.2 (2.4)kg/m(2); 35% lived ≤ 1 mile from a large supermarket, 42% lived >1 to 2 miles, and 22% lived >2 miles. Compared to children living >2 miles from a large supermarket, those who lived within 1 mile had a BMI 1.06 kg/m(2) higher. Adjustment for socioeconomic characteristics and distance to fast-food restaurants attenuated this estimate to 0.77 kg/m(2). Living in any other distance category from a large supermarket and proximity to other food establishments were not associated with child BMI.
Living closer to a large supermarket was associated with higher BMI among preschool-age children who were overweight or obese.
本研究旨在探讨儿童肥胖与食品店距离之间的关联。
我们使用了 2006 年至 2009 年在马萨诸塞州进行的一项 RCT 中 438 名 2-6.9 岁且 BMI 超过第 85 百分位数的儿童的基线数据。我们使用地理信息系统来确定六种食品店的距离：1）便利店，2）面包店、咖啡店、糖果店，3）全套服务餐厅，4）大型超市，5）小型超市和 6）快餐店。主要结局是儿童的 BMI。
儿童平均（SD）BMI 为 19.2（2.4）kg/m2；35%的儿童居住在距离大型超市 1 英里以内，42%的儿童居住在 1 至 2 英里之间，22%的儿童居住在 2 英里以上。与居住在距离大型超市 2 英里以上的儿童相比，居住在 1 英里以内的儿童 BMI 高 1.06kg/m2。调整社会经济特征和与快餐店的距离后，该估计值降低至 0.77kg/m2。居住在大型超市其他距离范围内或靠近其他食品店与儿童 BMI 无关。
居住在大型超市附近与超重或肥胖的学龄前儿童的 BMI 较高有关。
