Overview

Systematic review and meta-analysis finds physical activity interventions improve body mass index in school pupils, highlighting a public health approach.

Key Points

  • Physical activity interventions led to a reduction in body mass index (BMI) among pupils aged 10–19, indicating effective weight management strategies.
  • The analysis included 23 studies with 9441 pupils, showing a random effect size of −0.12 kg/m² BMI compared to controls.
  • Assessment followed systematic review protocols that ensured proper data extraction and analysis techniques to validate results.
  • Findings support health behaviour changes in secondary schools as vital to addressing public health issues related to obesity.
