The impact of community-based childhood obesity prevention interventions in Australia by socio-economic position: An individual participant data meta-analysis.

ABSTRACT:

Introduction

Community-based interventions (CBIs) to prevent childhood obesity show promise in reducing body mass index z-scores (zBMI). Assessing whether this approach produces equitable outcomes across socio-economic sub-groups is typically limited by inadequate sample size. This study aimed to assess the effectiveness of CBIs on zBMI and weight-related behaviours by socio-economic position (SEP).

Methods

Individual participant data meta-analysis using seven Australian childhood obesity prevention CBIs conducted between 2003 and 2022. Trials used consistent intervention approaches, objectively measured height and weight, and self- or parent-reported behaviours, and lasted 2-4 years. Area-level SEP was estimated using Australian Index of Relative Socio-economic Advantage an
