Prior studies have demonstrated disproportionate clustering of fast food outlets around schools.
The purpose of this study is to determine if racial/ethnic differences in middle school student self-reported sugar-sweetened beverage (SSB) consumption is explained by differential distributions of food outlets surrounding their schools.
Baseline (2005) data were analyzed from 18,281 middle school students in 47 Massachusetts schools participating in Healthy Choices, an obesity prevention program. Linear mixed effects models were used to examine the association of individual race/ethnicity and daily SSB consumption and the potential mediating effect of the density of food outlets (the number of fast food outlets and convenience stores in a 1500 m buffer area surrounding the school) on this association adjusting for individual and school demographics.
More SSB consumption was reported by students of all racial/ethnic minority groups compared to their White peers except Asians. The density of fast food restaurants and convenience stores was not associated with individual SSB consumption (β=0.001, p=0.875) nor did it mediate the association of race/ethnicity and SSB consumption.
Racial and ethnic differences in SSB consumption among MA middle school students cannot be fully explained by the location of fast food restaurants and convenience stores.
先前的研究表明，快餐店在学校周围的分布不成比例。
本研究旨在确定中学生自我报告的含糖饮料（SSB）消费的种族/民族差异是否可以通过其学校周围食品店的分布差异来解释。
对参加肥胖预防计划“健康选择”的马萨诸塞州 47 所学校的 18281 名中学生进行了基线（2005 年）数据分析。采用线性混合效应模型，考察个体种族/民族和每日 SSB 消费的相关性，以及食品店密度（学校周围 1500 米缓冲区内快餐店和便利店的数量）对这一相关性的潜在中介效应，调整个体和学校人口统计学因素。
除了亚洲人之外，所有少数族裔群体的学生 SSB 消费报告均高于其白人同龄人。快餐店和便利店的密度与个体 SSB 消费无关（β=0.001，p=0.875），也不能中介种族/民族与 SSB 消费之间的关系。
马萨诸塞州中学生 SSB 消费的种族和民族差异不能完全用快餐店和便利店的位置来解释。
