Hypothesis
Does increased physical activity at school improve the nutritional behavior and BMI of adolescents aged 13 years?
Conclusion
Extended physical activity at school has a beneficial effect on BMI but little effect on nutritional behavior among adolescents.
Supporting Evidence
- 62% of adolescents had a normal body weight.
- Extended physical activity led to a lower average BMI compared to standard physical activity.
- Adolescents with extended physical activity showed slightly better nutritional behaviors.
Takeaway
Kids who exercise more at school are less likely to be overweight, but they still don't eat as healthy as they should.
Methodology
The study involved 213 adolescents from six schools, comparing those with standard and extended physical activity programs.
Potential Biases
Convenience sampling may introduce selection bias.
Limitations
The study was limited to a small group and did not account for economic factors or the impact of COVID-19 on physical activity.
Participant Demographics
Participants were 13-year-old adolescents, with a mix of boys and girls.
