开展一项学生营养和锻炼 (SNaX) 随机对照试验，这是一项为期 5 周的以中学为基础的肥胖预防干预措施，结合了全校范围的环境变化、多媒体、鼓励吃健康的学校食堂食物和同伴主导的教育。我们从洛杉矶联合学区随机选择学校（五所干预学校，五所候补名单控制学校）。获得了学校提供的水果和蔬菜数量、学生提供的午餐以及每位在校学生出售的零食的记录，平均每所干预学校有 1,515 名学生 (SD=323)，每所对照学校有 1,524 名学生 (SD=266)。共有 2,997 名七年级学生（占全校七年级学生的 75%）完成了干预前后评估心理社会变量的调查。与基于社区的参与性研究原则相一致，学区是平等的合作伙伴，社区咨询委员会提供了重要的意见。与对照学校相比，干预学校为学生提供水果和午餐的比例显着增加，而学生在学校购买零食的比例显着下降。具体来说，与没有干预的情况相比，干预措施使水果供应量相对增加了 15.3%（p=0.006），午餐供应量增加了 10.4%（p<0.001），零食销量减少了 11.9%（p<0.001）。干预前后，与对照组学生相比，干预学校的学生对食堂食物（p = 0.02）和自来水（p = 0.03）有更积极的态度，有更多的预防肥胖知识（p = 0.006），喝自来水（p = 0.04）或可重复灌装的瓶子（p = 0.02）的意愿增加，并且消耗更多的自来水（p = 0.04）。以学校为基础的多层次干预措施可以促进健康的青少年饮食行为。
To conduct a randomized controlled trial of Students for Nutrition and eXercise (SNaX), a 5-week middle-school-based obesity-prevention intervention combining school-wide environmental changes, multimedia, encouragement to eat healthy school cafeteria foods, and peer-led education. We randomly selected schools (five intervention, five wait-list control) from the Los Angeles Unified School District. School records were obtained for number of fruits and vegetables served, students served lunch, and snacks sold per attending student, representing an average of 1,515 students (SD=323) per intervention school and 1,524 students (SD=266) per control school. A total of 2,997 seventh-graders (75% of seventh-graders across schools) completed pre-and post-intervention surveys assessing psychosocial variables. Consistent with community-based participatory research principles, the school district was an equal partner and a community advisory board provided critical input. Relative to control schools, intervention schools showed significant increases in the proportion of students served fruit and lunch and a significant decrease in proportion of students buying snacks at school. Specifically, the intervention was associated with relative increases of 15.3% more fruit served (p=0.006), 10.4% more lunches served (p<0.001), and 11.9% fewer snacks sold (p<0.001) than would have been expected in its absence. Pre-to-post intervention, intervention school students reported more positive attitudes about cafeteria food (p=0.02) and tap water (p=0.03), greater obesity-prevention knowledge (p=0.006), increased intentions to drink water from the tap (p=0.04) or a refillable bottle (p=0.02), and greater tap water consumption (p=0.04) compared to control school students. Multi-level school-based interventions may promote healthy adolescent dietary behaviors.
