Why the study?
Does higher cardiorespiratory fitness reduce the prevalence of carotid atherosclerosis in middle-aged and elderly men?
Population
9,871 Korean men aged 40-81 years
Comparison
High or moderate cardiorespiratory fitness… vs Low cardiorespiratory fitness
Design
Cross-sectional
Key result
High cardiorespiratory fitness was associated with a lower risk of carotid atherosclerosis compared to low fitness in men (OR 0.71; 95% CI 0.59-0.85; p<0.001).

Supports fitness-atherosclerosis association in men; leaves open whether interventions reduce plaque.

Does higher cardiorespiratory fitness reduce the prevalence of carotid atherosclerosis in middle-aged and elderly men?
Odds Ratio: 0.71 (95% CI 0.59–0.85)
Absolute Event Rate: 7.7% vs 11.7%
p-value: p=<0.001
Higher cardiorespiratory fitness is independently associated with a lower prevalence of carotid atherosclerosis in middle-aged and older men.
Lee et al. (2009) conducted a cross-sectional in Carotid atherosclerosis (n=9,871). High cardiorespiratory fitness vs. Low cardiorespiratory fitness was evaluated on Presence of carotid atherosclerosis (intima-media wall thickness >1.2 mm or stenosis >25%) (OR 0.71, 95% CI 0.59-0.85, p=<0.001). High cardiorespiratory fitness was associated with a lower risk of carotid atherosclerosis compared to low fitness in men (OR 0.71; 95% CI 0.59-0.85; p<0.001).
