Background and aim: Childhood obesity continues to be a global public health priority due to the significant burden it imposes on healthcare systems and society. Recent surveillance data indicates a substantial increase in childhood obesity prevalence during the COVID-19 pandemic. The review of childhood obesity prevention interventions (0−18 years) is the most rigorous and comprehensive review of randomized controlled trials (RCTs) on this topic. A burgeoning number of high quality studies have been published since that are yet to be synthesized. Methods: An update of the systematic review was conducted to include RCT studies in school-aged children (6-18 years) published to 30 June 2024 that assessed effectiveness on child weight. Available cost-effectiveness and adverse effect data were extracted. Intervention effects on body mass index (BMI) were synthesized in random effects meta-analyses by setting (school, after school program, community, home), and meta-regression examined the association of study characteristics with intervention effect. Results: Meta-analysis of 140 of 195 included studies found a very small positive effect on body mass index for school-based studies but not after-school programs, community or home-based studies. Subgroup analysis by age (6−12 years; 13−18 years) found no differential effects in any setting. Meta-regression found no associations between study characteristics (including setting, income level) and intervention effect. Ten of 53 studies assessing adverse effects reported presence of an adverse event. Insufficient data was available to draw conclusions on cost effectiveness. Conclusions: This updated synthesis of obesity prevention interventions for children aged 6−18 years, found a small beneficial impact on child BMI for school-based obesity prevention interventions. A more comprehensive assessment of interventions is required to identify mechanisms of effective interventions to inform future obesity prevention public health policy, which may be particularly salient in for COVID-19 recovery planning.
