The Effectiveness of School-Based Interventions on Obesity-Related Behaviours in Primary School Children: A Systematic Review and Meta-Analysis of Randomised Controlled Trials.

ABSTRACT: School-based interventions are promising for targeting a change in obesity-related behaviours in children.

Forty-eight studies met the inclusion criteria and were included in a narrative synthesis. Thirt
