Main finding · Incident CVDResult — go to the resultHazard ratio 2.81 95% CI 2.27–3.46Authors' conclusion
High daily step count was associated with lower CVD risk in individuals with moderate and high genetic risk
Study context
- Population

- Participants
- 84,286 participants
- Exposure
- Joint categories of genetic risk and accelerometer-measured daily step count
- Outcome
- Incident CVD:
- Coronary artery disease
- Ischaemic stroke
- Follow-up
- Median 7.9 years

As reported in the abstract
- High genetic risk and low step count independently associated with higher CVD risk; no multiplicative interaction
- P for interaction = 0.46
Observational data: associations, not effects.
Further findings
Dose-response of step count with CVD hazard
- Inverse dose-response up to 10,000 steps/day, then plateau in moderate and high genetic risk groups
