The diurnal pattern of moderate‐to‐vigorous physical activity and obesity: a cross‐sectional analysis
Authors' conclusion
The diurnal pattern of MVPA influences the association between MVPA and obesity. The promising role of morning MVPA for weight management warrants further investigation.
Study context
- Population
- Participants in the 2003 to 2006 National Health and Nutrition Examination Survey (NHANES) with objectively measured moderate-to-vigorous physical activity (MVPA)
- Participants
- 5,285 participants
- Exposure
- Morning vs midday vs evening MVPA diurnal pattern
- Morningn = 642
- Middayn = 2,456
- Eveningn = 2,187
- Outcome
- Association of MVPA level and diurnal pattern with obesity
Methodological detailsK-means clustering of objectively measured MVPA diurnal pattern
- K-means clustering of objectively measured MVPA diurnal pattern
Main finding
As reported in the abstract
MVPA–obesity association by diurnal pattern
- Strong linear association between MVPA and obesity in the morning group
- Weaker curvilinear association between MVPA and obesity in the midday and evening groups
Observational data: associations, not effects.
Further findings
Adjusted mean BMI among those meeting physical activity guidelines
Adjusted mean waist circumference among those meeting physical activity guidelines
