Objective: Children and adolescents with overweight or obesity are likely to have lower self-esteem compared to normal weight peers. Weight management interventions are successful at reducing BMI however, the effect on self-esteem is unclear. This systematic review investigates the impact of weight management interventions in children and adolescents with overweight or obesity on self-esteem.
Methods: Four databases were searched in May 2017 to retrieve peer-reviewed articles that met the following eligibility criteria: (1) children and adolescents with overweight or obesity, aged <18 years, (2) weight management intervention with a nutrition component, (3) case studies, pre-post studies and randomised controlled trials (RCTs), (4) pre- and post-intervention assessment of self-esteem using a validated tool.
Results: Of 2799 articles screened, 40 studies (9.3-15.6 years, n=10131) met the inclusion criteria. Meta-analyses showed a medium positive effect for self-esteem post-intervention (one week to 15 months) (standardised mean difference (SE) = 0.42 [0.05] p<0.001). Sixteen studies had follow-up measurements (2.5 months to 2.4 years post-intervention) which indicated the effect was maintained (0.36 [0.05], p<0.001). However, the effect is unlikely to be clinically significant. Analysis of RCTs (eight studies), supported these findings. Studies with a targeted self-esteem component had a larger effect (0.558 [0.13], p<0.001) than studies with no self-esteem component (0.373 [0.05], p<0.001). Studies which included parental involvement had a larger effect (0.417 [0.05], p<0.001) than studies with no parental involvement (0.365 [0.06], p<0.001). In terms of setting, there was no difference in effect between inpatient programs (0.477 [0.23], p=0.038), outpatient programs (0.452 [0.06], p<0.001) and summer camps (0.440 [0.06], p<0.001), with the smallest effect observed in a community setting (0.319 [0.05], p<0.001).
Conclusion: Engagement in weight management interventions was not associated with a decrease in self-esteem. The inclusion of targeted self-esteem components within weight management may lead to a clinically significant improvement.
