Main finding
As reported in the abstract
Associations with body composition (cross-sectional, adjusted for social-demographic and growth-related factors) · 13 years
- Each additional hour of daily physical activity associated with lower fat mass, abdominal visceral fat mass and higher lean body mass
- all p < 0.05
- Each additional hour of daily screen time associated with higher BMI, fat mass, abdominal subcutaneous and visceral fat mass
- all p < 0.05
Observational data: associations, not effects.
Further findings
- Physical activity associations not observed in longitudinal analyses
- Screen time associations consistent with longitudinal analyses
