Young adolescents with functional limitations engage in less light and moderate-to-vigorous physical activity (MVPA). Tailored interventions are needed to address these disparities in physical activity for disabled youth.
Area of Science:
- Public Health
- Pediatrics
- Disability Studies
Background:
- Monitoring physical activity in adolescents with disabilities is a key research area.
- Functional limitations serve as a novel marker for understanding disabilities and their impact on physical activity.
- Adolescents with disabilities represent a diverse population with varied functional abilities.
Purpose of the Study:
- To investigate physical activity levels in young adolescents with and without functional limitations.
- To compare light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) between these groups.
- To explore differences in physical activity based on specific functional limitations.
Main Methods:
- The study involved 1436 adolescents aged 11-15 from the 2016 Finnish School-aged Physical Activity (FSPA) study.
- Physical activity was measured using hip-worn accelerometers over seven consecutive days.
- Data were analyzed using general linear regression models, disaggregated by functional limitations (e.g., seeing, hearing, moving).
Main Results:
- Approximately one in six adolescents reported functional limitations.
- Adolescents with functional limitations had significantly less LPA (7 min/day) and MVPA (8 min/day) compared to their peers.
- After adjusting for covariates, differences in LPA remained significant, while MVPA differences were no longer statistically significant, with variations noted across different functional limitations.
Conclusions:
- Significant variations in physical activity exist based on functional limitations and intensity.
- Understanding functional limitations is crucial for developing targeted physical activity promotion strategies for adolescents with disabilities.
- Personalized approaches are necessary to improve physical activity behaviors in this population.
