Input: Combined data from two eating disorder prevention programs based on a media literacy and advocacy approach indicate a reduction in the internalisation or acceptance of societal ideals relating to appearance at a 3- to 6-month follow-up (Kusel 1999; Neumark* 2000) [SMD -0.28, -0.51 to -0.05, 95% CI]. There is insufficient evidence to support the effect of five programs designed to address eating attitudes and behaviours and other adolescent issues in the general community or those classified as being at high risk for eating disorder (Buddeberg* 1998; Dalle Grave 2001; Killen 1993; Santonastaso 1999; Zanetti 1999) and insufficient evidence to support the effect of two programs designed to improve self-esteem (O'Dea 2000; Wade 2003). Data from two didactic eating disorder awareness programs could not be pooled for analysis. There is not sufficient evidence to suggest that harm resulted from any of the prevention programs included in the review. The one significant pooled effect in the current review does not allow for any firm conclusions to be made about the impact of prevention programs for eating disorders in children and adolescents, although none of the pooled comparisons indicated evidence of harm. The meta-analysis is in the process of being revised to account for the impact of cluster randomised trials.
Output:

Several eating disorder prevention programs have been developed and trialled with children and adolescents. There is currently limited evidence in the published literature to suggest that any particular type of program is effective in preventing eating disorders and there has been concern that some interventions have the potential to cause harm. The aim of this systematic review is to determine whether these interventions are effective in the prevention of eating disorders in children and adolescents. Only one statistically significant result was found in the present meta-analysis - a slight effect of media literacy and advocacy programs in reducing acceptance of societal body image ideals. There is not sufficient evidence to suggest that harm was caused by any of the 12 randomised controlled trials included in the review at short-term follow-up. The meta-analysis is in the process of being revised to account for the impact of cluster randomised trials.
