Abstract

Objective: Adolescents are particularly susceptible to developing an eating disorder (ED). Therefore, schools are in a unique position to assist in the prevention of EDs for this vulnerable group. To ascertain the current evidence-base for school-based ED prevention efforts, we conducted a systematic review and meta-analysis of randomised controlled trials that delivered a school-based ED prevention intervention and assessed the impact these interventions had on ED symptomatology.

Method: Electronic databases (PsycINFO, MEDLINE, EMBASE, Web of Science, Scopus and CENTRAL) were searched for published randomised controlled trials of school-based ED prevention interventions from inception to 2024. Twelve studies from 11 articles were identified with 7935 participants (mean ages ranging from 12 to 17). Of these studies, six were included in meta-analyses.

Results: Media literacy and dissonance-based interventions reported small to medium effects for ED symptomatology compared to controls at post-intervention. At three-to-six-month follow-up, intervention groups reported small negative to medium-sized positive effects compared to control groups on eating disorder symptomatology.

Conclusions: While school-based ED prevention interventions can effectively reduce ED symptomatology post-intervention, the programs analysed in this review do not reliably demonstrate effectiveness across groups and time. Future research should build upon current interventions to increase effectiveness and include long-term follow-ups.

学校饮食失调症预防干预措施的系统回顾和荟萃分析。

目的：青少年特别容易患饮食失调症（ED）。因此，学校在帮助这一弱势群体预防饮食失调症方面具有独特的优势。为了确定目前以学校为基础的饮食失调症预防工作的证据基础，我们对提供以学校为基础的饮食失调症预防干预措施的随机对照试验进行了系统回顾和荟萃分析，并评估了这些干预措施对饮食失调症症状的影响：在电子数据库（PsycINFO、MEDLINE、EMBASE、Web of Science、Scopus 和 CENTRAL）中搜索了从开始到 2024 年发表的校本 ED 预防干预随机对照试验。结果发现了 11 篇文章中的 12 项研究，共有 7935 名参与者（平均年龄为 12 至 17 岁）。在这些研究中，有六项被纳入荟萃分析：与干预后的对照组相比，媒体扫盲和基于不和谐因素的干预对性欲障碍症状有小幅到中幅的影响。在三到六个月的随访中，与对照组相比，干预组对饮食失调症状有小幅负面到中幅正面影响：结论：虽然基于学校的进食障碍预防干预能有效减少干预后的进食障碍症状，但本综述中分析的项目并不能可靠地证明其在不同群体和不同时间的有效性。未来的研究应在现有干预措施的基础上提高有效性，并进行长期跟踪。
