Habitual physical activity and central artery stiffening in older adults
Key result
High physical activity was associated with lower central arterial stiffness (adjusted mean difference -0.38 m/s) compared with no physical activity in community-dwelling older adults.
Why the study?
Does moderate or high physical activity reduce central arterial stiffness and pressure pulsatility in community-dwelling older adults?
Population
3893 community-dwelling older adults in a prospective cohort study.
Comparison
Moderate or high physical activity, including… vs No physical activity.

Implication
May support promoting physical activity for vascular health in older adults; hypothesis-generating for prospective trials on stiffness reduction.

Cohort (n=3,893)
Structured PICO
Does moderate or high physical activity reduce central arterial stiffness and pressure pulsatility in community-dwelling older adults?
P
Population
3,893 community-dwelling older adults evaluated for the association between physical activity and central arterial stiffness.
E
Exposure
Moderate or high physical activity, including persistent physical activity from mid-life to late-life.
C
Comparator
No physical activity.
O
Outcome
Central arterial stiffness (measured via carotid-femoral pulse wave velocity or cfPWV) and pressure pulsatility (measured via central pulse pressure or cPP).surrogate
Main Result
Mean Difference: -0.38
Higher physical activity in late-life, as well as persistent habitual physical activity from mid-life to late-life, is associated with lower central arterial stiffness and pressure pulsatility in older adults.

Tanaka et al. (2018) reported a cohort. Physical activity vs. No physical activity was evaluated on Central arterial stiffness (cfPWV) (MD -0.38 m/s). High physical activity was associated with lower central arterial stiffness (adjusted mean difference -0.38 m/s) compared with no physical activity in community-dwelling older adults.
