Supports adjustment for physical activity in carotid imaging studies; leaves open independent effects on intima-media thickness.
Does physical activity affect carotid intima-media thickness in stage 1 hypertensives and normotensive controls?
Physical activity is an early independent predictor of increased carotid wall thickness and acts cumulatively with hypertension, suggesting it should be accounted for as a confounder in vascular imaging studies.
Casiglia et al. (2000) studied this question.
