社会经济地位低的学校往往出售较少的健康竞争性食品/饮料。这项研究探讨了国家竞争性食品法是否可以减少这种差距。五年级和八年级的学校管理人员报告在学校出售的食品和饮料，从这些数据构建的食品/饮料环境的指数措施。学校根据学生邮政编码的家庭收入中位数分为SES三分位数。回归模型用于估计SES差异：（1）健康学校食品环境指数（HSFEI）得分，健康学校饮料环境指数（HSBEI）得分和特定食品/饮料销售，以及（2）州竞争性食品/饮料法律与HSFEI得分，HSBEI得分和特定食品/饮料销售之间的关联。强竞争力的食物法与HSFEI在8年级呈正相关，无论SES。强有力的竞争性饮料法与HSBEI呈正相关，特别是在低社会经济地位的学校在8年级。这些关联归因于学校销售较少的不健康物品，而不是提供健康的替代品。不管州法律如何，高社会经济地位的学校比低社会经济地位的学校出售更多的健康物品。强有力的竞争食品法可能会减少获得不健康的食品/饮料在中学，但需要额外的举措，为学生提供健康的选择，特别是在低社会经济地位地区。
Schools of low socioeconomic status (SES) tend to sell fewer healthy competitive foods/beverages. This study examined whether state competitive food laws may reduce such disparities. Fifth- and 8th-grade school administrators reported foods and beverages sold in school; index measures of the food/beverage environments were constructed from these data. Schools were classified into SES tertiles based on median household income of students’ ZIP code. Regression models were used to estimate SES differences in: (1) Healthy School Food Environment Index (HSFEI) score, Healthy School Beverage Environment Index (HSBEI) score, and specific food/beverage sales, and (2) associations between state competitive food/beverage laws and HSFEI score, HSBEI score, and specific food/beverage sales. Strong competitive food laws were positively associated with HSFEI in 8th grade, regardless of SES. Strong competitive beverage laws were positively associated with HSBEI particularly in low-SES schools in 8th grade. These associations were attributable to schools selling fewer unhealthy items, not providing healthy alternatives. High-SES schools sold more healthy items than low-SES schools regardless of state laws. Strong competitive food laws may reduce access to unhealthy foods/beverages in middle schools, but additional initiatives are needed to provide students with healthy options, particularly in low-SES areas.
