Association of physical activity with arterial stiffness among Black adults
Key result
Higher exercise levels linked to ~11% lower arterial stiffness in Black adults.
- P<0.001
- n=433
Why the study?
Physical activity has been associated with lower arterial stiffness in largely White populations, but the types of activity required and applicability to Black adults remain unknown.
Population
378 Black adults without known CVD in Atlanta, GA and 55 Black adults in an independent cohort
Comparison
Higher versus lower levels of sport/exercise and home/life physical activities
Design
Cohort study with multiple linear regression analysis and validation in independent cohort

Cite This Study
Baltrus et al. (2021) conducted a cohort in Arterial stiffness in Black adults without known CVD (n=433). Higher levels of sport/exercise and home/life-related physical activities vs. Lowest quartile of physical activity was evaluated on Arterial stiffness measured as pulse wave velocity (PWV) (p=<0.001). Higher levels of sport/exercise were associated with lower arterial stiffness compared to the lowest quartile (PWV 6.92 vs 7.75, p<0.001) among Black adults without known cardiovascular disease.
