# Physical activity level among male and female middle to high school students and impact of perceived school climate: a longitudinal analysis

## TL;DR

This study finds that physical activity declines with grade level, especially in girls, and that a positive school climate can help reduce this decline.

## Contribution

The study longitudinally examines gender-specific physical activity trends and links them to perceived school climate.

## Key findings

- Physical activity decline is more pronounced in females than males as they progress through school.
- Improved perception of school connectedness is strongly associated with higher physical activity levels.
- School climate improvements can mitigate the decline in adolescent physical activity.

## Abstract

Physical activity levels are declining among middle and high school students, and schools could provide an ideal space for engaging adolescents in physical activity. The study aimed to assess physical activity levels among male and female middle to high school students and the impact of perceived school climate.

This longitudinal study utilized the Georgia Student Health Survey (GSHS) from 2016 to 2020, with change in the proportion of physically active students as an outcome and school climate measures as predictors. Factor analysis yielded a composite index for each school climate measure. Descriptive analysis measured the trend and male vs. female differences in physical activity. A multivariable linear regression model was developed to assess the impact of school climate on physical activity and male–female differences.

The decline in physical activity with increasing grade levels was notably more pronounced in females than males. Improvement in the perception of school climate measures was consistently linked to an increased proportion of physically active students as they progressed to higher grades (for example, change in perception of school connectedness: β = 5.39; p < 0.001).

The study findings underscore the importance of fostering positive school climates to mitigate the decline in physical activity levels, especially among adolescent females.
