我们采用基于社区的参与性研究（CBPR）的原则，为中学生制定并进行为期5周的干预试验，学生营养和锻炼（SNaX）。SNaX旨在将学校预防肥胖政策转化为实践，倡导健康饮食和学校食堂的变化。干预学校的425名7年级学生（占所有7年级学生的63%）在基线时接受了关于自助餐厅态度和含糖饮料（SSB）消费的调查;在425名学生中，399名（94%）在干预后一个月再次接受调查。学校食堂的记录，从干预学校和非随机选择的比较学校具有相似的学生的社会人口特征。140名干预学校学生接受了同伴倡导者培训。在干预学校，同伴倡导者的自助餐厅态度随着时间的推移显着改善（~标准差的三分之一），而非同伴倡导者的自助餐厅态度保持稳定;同伴倡导者的改善显着大于非同伴倡导者的前后变化（B = 0.71，p <.001）。同伴倡导者显著减少了他们的SSB摄入量（运动和水果饮料），从干预前的33%减少到干预后的21%（p = .03）。食堂记录表明，水果和健康主菜（沙拉，三明治，酸奶冻糕）的供应量在对照学校显着减少，而在干预学校显着增加;学校之间的变化幅度显着不同（p <.001）。同伴倡导者似乎比非同伴倡导者更能从干预中受益。未来的研究应考虑让家长、学生和其他关键的社区利益相关者参与进来，以确定可接受和可持续的自助餐厅变革。
We used principles of community-based participatory research (CBPR) to develop and pilot test a 5-week intervention for middle school students, Students for Nutrition and eXercise (SNaX). SNaX aimed to translate school obesity-prevention policies into practice with peer advocacy of healthy eating and school cafeteria changes. 425 7th graders in the intervention school (63% of all 7th graders) were surveyed at baseline regarding cafeteria attitudes and sugar-sweetened beverage (SSB) consumption; of the 425 students, 399 (94%) were surveyed again at one-month post-intervention. School cafeteria records were obtained from the intervention school and a non-randomly selected comparison school with similar student socio-demographic characteristics. 140 intervention school students were trained as peer advocates. In the intervention school, cafeteria attitudes among peer advocates significantly improved over time (~one-third of a standard deviation), whereas non-peer advocates’ cafeteria attitudes remained stable; the improvement among peer advocates was significantly greater than the pre-post change for non-peer advocates (b = 0.71, p <.001). Peer advocates significantly reduced their SSB intake (sports and fruit drinks), from 33% pre-intervention to 21% post-intervention (p = .03). Cafeteria records indicated that servings of fruit and healthier entrees (salads, sandwiches, yogurt parfaits) significantly decreased in the comparison school and significantly increased in the intervention school; the magnitude of changes differed significantly between schools (p <.001). Peer advocates appeared to benefit from the intervention more than did non-peer advocates. Future research should consider engaging parents, students, and other key community stakeholders to determine acceptable and sustainable cafeteria changes.
