目的：为了评估肥胖预防干预的影响，使用自我诱导的呕吐/泻药（清洗）和减肥药，以控制体重的女孩在青春期早期。设计：我们匹配，并随机分配10所中学的干预或控制条件的随机对照试验。使用广义估计方程对480名女孩的数据进行纵向多变量分析，以检查干预措施对报告新的排毒或使用减肥药控制体重的风险的影响，同时控制种族和学校配对。研究对象：480名10 - 14岁青春期早期的女孩，年龄在10 - 14岁之间，年龄在10 - 14岁之间（平均年龄，11.5岁）.干预：行星健康肥胖预防计划在2个学年期间实施，旨在促进健康营养和体育活动，并减少看电视。干预后，我们发现对照学校的226名女孩中有14名（6.2%），干预学校的254名女孩中有7名（2.8%）报告说，他们通过减肥或服用减肥药来控制体重（P = 0.003）。在一个多变量广义估计方程模型中，干预学校的女孩在随访时报告排毒或使用减肥药的可能性不到对照学校女孩的一半（比值比，0.41; 95%置信区间，0.22-0.75）。结果：降低风险，使用自我诱发的呕吐/泻药或减肥药，以控制体重在过去的30 days.Conclusion：这些研究结果提供了有希望的证据，以学校为基础的干预措施可以有效地整合预防肥胖和体重控制行为紊乱。
Objective: To assess the impact of an obesity prevention intervention on use of self-induced vomiting/ laxatives (purging) and diet pills to control weight in girls in early adolescence.Design: We matched and randomly assigned 10 middle schools to an intervention or a control condition in a randomized controlled trial. Longitudinal multivariable analyses using generalized estimating equations were conducted with data from 480 girls to examine the effects of the intervention on the risk of reporting a new case of purging or diet pill use to control weight at follow-up 21 months later, while controlling for ethnicity and school matched pairs. Girls who reported purging or using diet pills at baseline were excluded from analyses.Setting: Middle schools.Participants: Four hundred eighty girls in early adolescence aged 10 to 14 years (mean age, 11.5 years).Intervention: The Planet Health obesity prevention program was implemented during 2 school years and was designed to promote healthful nutrition and physical activity and to reduce television viewing.Results: After the intervention, we found 14 (6.2%) of 226 girls in control schools and 7 (2.8%) of 254 girls in intervention schools reported purging or using diet pills to control their weight (P =.003). In a multivariable generalized estimating equation model, girls in intervention schools were less than half as likely to report purging or using diet pills at follow-up compared with girls in control schools (odds ratio, 0.41; 95% confidence interval, 0.22-0.75). Outcome: Reduced risk of using self-induced vomiting/ laxatives or diet pills to control weight in the past 30 days.Conclusion: These findings provide promising evidence that school-based interventions may effectively integrate prevention of both obesity and disordered weightcontrol behaviors.
