目的：研究青少年的身体质量指数与学校范围内的饮食习惯之间的关系，如学校筹款和课堂上作为奖励和奖励使用的食物。设计：采用横断面研究设计，我们从学校和学生中收集数据。学校管理人员提供了全校食品政策和做法的信息。八年级学生提供了自我报告的身高和体重。环境：位于明尼阿波利斯-圣保罗大都会区的16所中学。参与者：该研究包括3088名八年级学生。学生们参加了一项以学校为基础的饮食干预研究。主要观察指标：体重指数根据自我报告的身高和体重数据计算。使用从学校管理人员收集的数据，创建了一个包含7个项目的全校食品实践量表（Cronbach alpha = 0.83）。结果：一所学校平均允许的食品实践数为3个（范围0-7）。最普遍的食物做法是使用食物作为激励和奖励（69%）和教室筹款（56%）。每增加一次学校允许的饮食练习，学生的身体质量指数增加10% (P
Objective: To examine the association between body mass index in young adolescents and schoolwide food practices such as foods used in school fundraising and in the classroom as incentives and rewards.Design: Using a cross-sectional study design, we collected data from both the schools and the students. School administrators provided information on schoolwide food policies and practices. Eighth-grade students provided self-reported heights and weights.Setting: Sixteen middle schools in the Minneapolis-St Paul metropolitan area.Participants: The study included 3088 eighth-grade students. Students were participants in a school-based dietary intervention study.Main Outcome Measures: Body mass index was calculated from self-reported height and weight data. A 7-item schoolwide food practices scale (Cronbach alpha = 0.83) was created using data collected from school administrators.Results: The mean number of food practices permitted by a school was 3 (range, 0-7). The most prevalent food practices were the use of food as incentives and rewards (69%) and in classroom fundraising (56%). Body mass index of the students increased 10% for every additional food practice permitted in their school (P
