Arrhythmias & electrophysiology
Fitbit-measured physical activity is inversely associated with incident atrial fibrillation among All of Us participants
Authors' conclusion
Higher amounts of objectively measured MVPA, measured using free-living, long-term accelerometry data, were inversely associated with risk of incident AF, independent of clinical and genetic risk factors.
Study context
- Population
- All of Us participants with 1-year Fitbit data
- Participants
- 15,570 participants
- Exposure
- Higher vs lower Fitbit-measured moderate to vigorous physical activity (MVPA)
- Outcome
- Incident AF
- Follow-up
- five-year follow-up
Methodological detailsAll of Us research database
- All of Us research database
Main finding
As reported in the abstract
Incident AF per additional hour of MVPA · 5-year follow-up
Incident atrial fibrillation (AF)
97 individuals
0.6%
Observational data: associations, not effects.
Further findings
Incident AF per hour MVPA, adjusted for AF genetic risk score (subset with genomic data)
- Association persisted after adjustment for AF genetic risk score (n = 10533)
