The impact of behavioral weight management interventions on eating behavior traits in children with overweight or obesity: Systematic review and meta-analysis.

INTRODUCTION

Behavioral weight management interventions (BWMIs) are an evidence-based strategy for addressing childhood obesity. Targeting eating behavior traits (EBTs; individual tendencies determining food intake/occasions) could play a pivotal role in improving the effectiveness of these behavioral interventions. The present study describes a systematic review and meta-analysis of the impact of BWMIs on eating behavior traits in children with overweight or obesity.

METHODS

Seven databases were searched, and eligible studies included randomized controlled trials reporting EBT outcomes following BWMIs delivered to children with overweight or obesity (<18 years of age). Random effects meta-analyses were conducted to compare EBT outcomes for intervention and control groups. Synthesis without meta-analysis (SWiM) was applied for EBTs where meta-analysis was not feasible.

RESULTS

The review identified eight trials characterizing the impact of BWMIs on 15 EBTs. Meta-analyses of data from three trials at intervention completion and post-intervention (average of 28 weeks [±8]) revealed positive short-term increases in dietary restraint (SMD random effect 0.42 [95% CI 0.13, 0.70]). However, these effects were not sustained at follow-up. Improvements in emotional eating, external eating, food responsiveness, and enjoyment of food were shown in studies which could not be pooled quantitatively.

CONCLUSION

BWMIs in children living with overweight/obesity are beneficial for the improvement of some EBTs at intervention completion including dietary restraint, emotional eating, external eating, food responsiveness, and enjoyment of food. However, this remains a relatively unexplored area and more research is needed to strengthen understanding of the multifaceted impact of child BWMIs on a comprehensive range of EBTs.
