The school effect on children's school time physical activity: the PEACH Project

Area of Science:

• Pediatric Health
• Epidemiology
• Behavioral Science

Background:

• The school environment is a critical factor for children's physical activity.
• Limited research has explored the impact of the specific school attended on children's physical activity levels.
• Understanding school-level influences is crucial for developing effective public health strategies.

Purpose of the Study:

• To investigate the association between the school attended and children's physical activity.
• To quantify the variance in physical activity attributable to school differences.
• To identify factors influencing school-time physical activity in children.

Main Methods:

• Utilized multilevel modeling (MLM) to analyze data from 1307 pupils aged 10-11 years across 23 primary schools in Bristol, UK.
• Measured physical activity using accelerometry (ActiGraph GT1M).
• Adjusted for individual-level and school-level variables to isolate the school effect.

Main Results:

• A significant school effect was identified, explaining 14.5% of the total variance in physical activity.
• Boys exhibited significantly higher physical activity than girls.
• The school attended explained a larger proportion of variance in boys' physical activity (23.4%) compared to girls' (12.2%).
• Seasonal variations and neighborhood economic deprivation were associated with children's school-time activity.

Conclusions:

• The study demonstrates a significant school effect on children's physical activity, underscoring the need to account for the school attended in future research.
• Multilevel modeling (MLM) is a suitable analytical approach for investigating school-level effects on physical activity.
• Further research is warranted to elucidate the specific school-based factors contributing to observed physical activity differences.
