Associations of Moderate-to-Vigorous Physical Activity Timing With Type 2 Diabetes Incidence in UK Biobank and Prevalent Glycemic Measures in National Health and Nutrition Examination Survey (NHANES)
Authors' conclusion
When keeping total MVPA volume constant, clustering MVPA in the afternoon-evening was associated with the strongest reduction in incident T2D risk, fewer prevalent diabetes, and more favorable glycemic measures.
Study context
- Population
- UK Biobank participants (prospective) and NHANES participants (cross-sectional) with accelerometer-derived moderate-to-vigorous physical activity (MVPA)UK Biobank (UKB) 84,528
- Exposure
- MVPA timing categories vs other timings
- Outcome
- Incident T2D (UK Biobank); prevalent diabetes and glycemic measures (NHANES)
Methodological detailsaccelerometer-derived MVPA timing, regression models

Main finding
As reported in the abstract
Incident T2D (UKB)
- Before adjustment for total MVPA, variable-timing MVPA was associated with the lowest incident T2D risk
- After adjustment for total MVPA, afternoon-evening MVPA (1500-2400) showed the lowest incident T2D risk
- Early morning MVPA as reference
Observational data: associations, not effects.
Further findings
Glycemic measures and diabetes prevalence (NHANES)
- Afternoon/early evening MVPA weakly associated with more favorable glycemic measures and lower diabetes prevalence after adjustment for total MVPA
- Cross-sectional
