Interpretive Summary:

Technical Abstract: Many adolescents without a diagnosed eating disorder report disordered eating, including weight control behaviors and body dissatisfaction. No previous review has described and compared weight-related interventions targeting weight status in this population. The aim was to compare the efficacy of weight-related alone interventions on BMI in adolescents versus with disordered eating behaviors. Electronic databases were conducted in July and August 2017 in MedLine/PubMed, PsycINFO, Web of Science and SciELO. The studies were restricted to randomized and quasi-experimental trials aiming to prevent obesity only or integrate obesity and eating disorder prevention. All studies targeted adolescents and had anthropometric measurements assessed at baseline and post-intervention. Following appraisal for risk of bias, extracted data were meta-analyzed using random-effects models. All analyses were conducted with RevMan (version 5.3). From 12,599 records identified through database searching, 156 full-texts were assessed. Twelve studies met inclusion criteria, seven of which were obesity only prevention and five were integrated obesity and eating disorder interventions. Meta-analyses showed no significant effect on weight status for obesity only intervention [Hedge's g -0.02 (95% confidence interval -0.27 to 0.23)] and integrated obesity and eating disorder intervention [g-0.47 (95%CI -0.98 to 0.05)]. The total effect size for the twelve studies were also non-significant [g-0.19 (95%CI -0.41 to 0.03)]. Integrated interventions assessed body satisfaction and showed low-significant effect [g=-0.36 (95%CI -0.64 to -0.07)] and intervention group were 29% less likely to present unhealthy weight control behaviors at post-intervention compared to controls. The most frequently used conceptual framework in obesity alone interventions was the social cognitive theory and in integrated intervention were cognitive dissonance and media literacy. Interventions targeting obesity only and integrated components in adolescents did not improve weight status in adolescents without an eating disorder. This lack of effect may be because most participants were normal weight at baseline. Additional investigations into broad-reaching interventions that promote healthy weight, and weight control behaviors, and positive body image are much needed.
