Device-Measured 24-Hour Movement Behaviors and Blood Pressure: A 6-Part Compositional Individual Participant Data Analysis in the ProPASS Consortium
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
Methodological detailsindividual participant data analysis, compositional data analysis, 6 cohorts
- Individual participant data analysis

- 6 cohorts
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.
