Association of physical activity, sedentary behavior, diet quality with adiposity: a longitudinal analysis in children categorized by baseline weight status
Authors' conclusion
MVPA was negatively associated with adiposity (FMI) in all weight status groups, suggesting that MVPA may protect against higher adiposity. Sedentary behavior and diet quality were associated with adiposity only in children with obesity at baseline; neither sedentary behavior nor diet quality was associated with FMI for children with overweight.
Study context
- Population
- Children (45% boys) followed from 5th grade to 6th and/or 7th grade45% boys
- Participants
- 658 children
- Exposure
- Associations of moderate-to-vigorous physical activity (MVPA), sedentary behaviour and diet quality with fat-mass-index (FMI), by baseline weight status
- Outcome
- Adiposity, operationalized as fat-mass-index (FMI)
- Follow-up
- 5th, 6th and/or 7th grades

Main finding
As reported in the abstract
Associations with FMI by baseline weight status
- MVPA was negatively associated with FMI for all weight status groups
- Diet quality and sedentary behavior were associated with adiposity only in children with obesity at baseline
- Neither diet quality nor sedentary behavior was associated with FMI in children with overweight
Observational data: associations, not effects.
