Obesity and eating disorders are public health problems that have lifelong financial and personal costs and common risk factors, for example, body dissatisfaction, weight teasing and disordered eating. Obesity prevention interventions might lead to the development of an eating disorder since focusing on weight may contribute to excessive concern with diet and weight. Therefore, the proposed research will assess whether integrating obesity and eating disorder prevention procedures ('integrated approach') do better than single approach interventions in preventing obesity among adolescents, and if integrated approaches influence weight-related outcomes.
Integrated obesity and eating disorder prevention interventions will be identified. Randomised controlled trials and quasi-experimental trials reporting data on adolescents ranging from 10 to 19 years of age from both sexes will be included. Outcomes of interest include body composition, unhealthy weight control behaviours and body satisfaction measurements. MEDLINE/PubMed, PsycINFO, Web of Science and SciELO will be searched. Data will be extracted independently by two reviewers using a standardised data extraction form. Trial quality will be assessed using the Cochrane Collaboration criteria. The effects of integrated versus single approach intervention studies will be compared using systematic review procedures. If an adequate number of studies report data on integrated interventions among similar populations (k>5), a meta-analysis with random effects will be conducted. Sensitivity analyses and meta-regression will be performed only if between-study heterogeneity is high (I ≥75%).
Ethics approval will not be required as this is a systematic review of published studies. The findings will be disseminated through conference presentations and peer-reviewed journals.
肥胖和饮食失调是公共卫生问题，会带来终身的经济和个人代价，且存在共同的风险因素，例如身体不满意、体重歧视和饮食紊乱。预防肥胖的干预措施可能会导致饮食失调的发生，因为关注体重可能会导致对饮食和体重的过度关注。因此，拟议的研究将评估整合肥胖和饮食失调预防程序（“综合方法”）在预防青少年肥胖方面是否比单一方法干预更有效，以及综合方法是否会影响与体重相关的结果。
将确定综合肥胖和饮食失调预防干预措施。纳入报告10至19岁青少年两性数据的随机对照试验和准实验试验。感兴趣的结果包括身体成分、不健康的体重控制行为和身体满意度测量。将检索MEDLINE/PubMed、PsycINFO、科学引文索引和拉丁美洲及加勒比地区在线科学电子图书馆。两名评审员将使用标准化的数据提取表独立提取数据。将使用Cochrane协作标准评估试验质量。将使用系统评价程序比较综合干预与单一方法干预研究的效果。如果有足够数量的研究报告了相似人群（k>5）中综合干预的数据，将进行随机效应荟萃分析。仅当研究间异质性较高（I²≥75%）时，才进行敏感性分析和荟萃回归。
由于这是对已发表研究的系统评价，因此无需伦理批准。研究结果将通过会议报告和同行评审期刊进行传播。
