Acute cardiac care & resuscitationCohort study
Association between accelerometer-derived physical activity and incident cardiac arrest
- Prospective cohort study
- UK Biobank
Authors' conclusion
Accelerometer-measured PA, particularly MPA and VPA, was associated with a lower CA risk. Furthermore, a stronger association was observed in women than men.
Study context
- Population
- UK Biobank participants with physical activity (PA) measured by wrist-worn accelerometers
- Participants
- 98,893 participants
- Exposure
- Accelerometer-measured PA and incident cardiac arrest (CA)
- Outcome
- Incident CA (diagnostic codes linked to hospital encounters and death records)
- Follow-up
- Median 7.31 years
Main finding
As reported in the abstract
Incident CA · median 7.31 years (IQR 6.78-7.82 years)
Incident CAs
282
Incidence rate
0.39 per 1000 person-years
CA risk decreased sharply until vigorous PA (VPA) reached ∼20 min per week, then relatively flat
20 min
Observational data: associations, not effects.
Further findings
PA and CA risk by sex (subgroup)
- More pronounced association between PA and reduced CA risk in women than men
