Competencies for health‐enhancing physical activity are associated with body mass: results of an updated data pooling across 18 samples
Authors' conclusion
This study adds to associations between BMI and PA levels by specifying individuals' multidimensional requirements for health-enhancing PA. The present findings call for an integration of physical, motivational, and cognitive factors in practices of PA promotion and sustainable obesity treatment.
Study context
- Population
- Individuals from a large data pooling of 18 primary samples using the PAHCO instrument; mean (SD) BMI 25.54 (5.71) kg/m², age 46.11 (14.96) years18 samples
- Participants
- 3,670 individuals
- Exposure
- Physical activity (PA)-related health competence indicators across BMI categories
- Outcome
- Differences in 10 PAHCO indicators by BMI category and their courses across the BMI spectrum
