Device-Measured 24-Hour Movement Behaviors and Blood Pressure: A 6-Part Compositional Individual Participant Data Analysis in the ProPASS Consortium
- Cross-sectional study
- individual participant data analysis
- compositional data analysis
- 6 cohorts
Authors' conclusion
Study findings reiterate the importance of exercise for BP control, suggesting that small additional amounts of exercise are associated with lower BP in a free-living setting.
Study context
- Population
- Adults with thigh-worn accelerometer and blood pressure (BP) data from 6 ProPASS cohorts (mean±SD age 54.2±9.6 years)
- Participants
- 14,761 adults · 6 cohorts
- Exposure
- Reallocation of time between 24-hour movement behaviours
- Outcome
- SBP and DBP
Main finding
As reported in the abstract
Estimated BP reduction with an additional 5 minutes of exercise-like activity
Estimated reduction, mm Hg
- Systolic BP (SBP)
- −0.68 (95% CI −0.15 to −1.21)
- Diastolic BP (DBP)
- −0.54 (95% CI −0.19 to 0.89)
- Clinically meaningful improvements in SBP estimated after reallocation into additional exercise
- 20 to 27 minutes
- Clinically meaningful improvements in DBP estimated after reallocation into additional exercise
- 10 to 15 minutes
Observational data: associations, not effects.
