Hypothesis
Does moderate-to-vigorous physical activity attenuate prospective weight gain among African-origin adults?
Conclusion
Higher levels of moderate-to-vigorous physical activity do not prevent weight gain over time in African-origin adults.
Supporting Evidence
- The obesity prevalence increased from 27.5% at baseline to 38.0% at follow-up.
- Baseline moderate-to-vigorous physical activity varied significantly across different populations.
- Every additional 30 minutes of moderate-to-vigorous physical activity was associated with a 600g lower body weight.
Takeaway
Even if people exercise more, they might still gain weight over time.
Methodology
Participants were recruited and followed up over 8 years, with accelerometry used to measure physical activity.
Limitations
The study may not account for all confounding factors affecting weight change.
Participant Demographics
Adults from Ghana, South Africa, Jamaica, Seychelles, and the US, median age 37 years.
