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

Obesity prevention CBIs may have greater impacts among children from low SEP areas, potentially contributing to reducing health inequities. Further research is needed to understand barriers to improving weight-related behaviours across socio-economic groups.
Study context
- Population
- Australian children in childhood obesity prevention CBI trials lasting 2–4 years; area-level socio-economic position (SEP) as Australian Index of Relative Socio-economic Advantage and Disadvantage tertiles from home or school postcodes7 community-based interventions (CBIs) · 25,346 observations
- Comparison
- Community-based childhood obesity prevention interventions (CBIs) vs control, by socio-economic position (SEP)
- Outcome
- zBMI and weight-related behaviours by SEP
