Pulmonary vascular disease & thromboembolismCohort study

Accelerometer-measured intensity-specific physical activity, genetic predisposition, and the risk of venous thromboembolism: a cohort study

Eur J Prev CardiolPublished

  • Prospective cohort study

Authors' conclusion

Higher levels of physical activity of any intensity were associated with a lower risk of new-onset VTE. However, the negative association between moderate-to-vigorous-intensity physical activity and new-onset VTE was significant only in participants with low and intermediate genetic predispositions to VTE.

Study context

Population
UK Biobank participants with accelerometer-measured physical activity, accounting for genetic risk (venous thromboembolism (VTE) polygenic risk score (PRS))1,182 incident VTE cases
Participants
85,116 participants
Exposure
Highest vs lowest level of accelerometer-measured physical activity
Outcome
Incident VTE (linked hospital records and death registries)
Follow-up
Median 6.18 years

Main finding

As reported in the abstract

Highest level vs Lowest levelHazard ratio (95% CI)

Observational data: associations, not effects.

Further findings

VTE by genetic risk (PRS) subgroup

Total and light-intensity physical activity negatively associated with VTE risk in low, intermediate and high PRS
Moderate-to-vigorous-intensity physical activity protective only in low and intermediate PRS
