Summary Objective: To systematically reviewand quantify the effectiveness of Eating Disorder (ED) prevention interventions.Methods: Electronic databases (including the Cochrane Controlled Trial Register,MEDLINE, PsychInfo, EMBASE, andScopus) were searched for published randomized controlled trials of ED prevention interventions from 2009 to2015. Trials prior to 2009 were retrieved from prior reviews.Results: One hundred and twelve articles were included. Fifty-eight percent of trials had high risk of bias. Findingsindicated small to moderate effect sizes on reduction of ED risk factors or symptoms which occurred up to threeyearpost-intervention. For universal prevention, media literacy (ML) interventions significantly reduced shapeand weight concerns for both females (−0.69, confidence interval (CI): −1.17 to −0.22) and males (−0.32, 95%CI−0.57 to−0.07). For selective prevention, cognitive dissonance (CD) interventions were superior to control interventionsin reducing ED symptoms (−0.32, 95% CI−0.52 to−0.13). Cognitive behavioural therapy (CBT) interventionshad the largest effect size (−0.40, 95% CI−0.55 to−0.26) on dieting outcomeat 9-month follow-upwhilethe healthy weight intervention reduced EDrisk factors and body mass index.No indicated prevention interventionswere found to be effective in reducing ED risk factors.Conclusions: There are a number of promising preventive interventions for ED risk factors including CD, CBT andML.Whether these actually lower ED incidence is, however, uncertain. Combined ED and obesity prevention interventionsrequire further research.
