Long-Distance Skiing and Incidence of Hypertension
- Cohort study
- matched on age, sex and place of residence
Authors' conclusion
Participation in a long-distance skiing event was associated with a 41% lower incidence of hypertension over the next 8 years compared with nonparticipation. A near linear association between performance and incidence of hypertension was observed.
Study context
- Population
- Participants in Vasaloppet and matched general-population controls
- Participants
- 206,889 vs 505,542
- Exposure
- Long-distance skiers vs nonskiers from the general population
- Skiersn = 206,889
- Nonskiersn = 505,542reference
- Outcome
- Incidence of hypertension (prescription of BP-lowering drugs, national drug registry)
- Follow-up
- Median time at risk 8.3 years
