Abstract

Impairment of vascular endothelial function is an early sign of atherosclerosis. An active lifestyle is suggested to be positively associated with favorable endothelial function as opposed to a sedentary lifestyle.

The aim of this ongoing study (Lifestyle, Biomarkers and Atherosclerosis Study) is to investigate associations between vascular endothelial function and physical activity level in 1000 non-smokers without know disease aged 18-25 years. Preliminary data from the 317 first subjects with complete data will be reported here.

Flow-mediated dilation was assessed in a. brachialis by high-resolution ultrasound (Vivid e9) before and after 5-minutes occlusion, and time spent active (at moderate or vigorous intensity level) or sedentary was assessed by accelerometry (ActiGraph wGT3X-BT).

Multiple regression analyses show that time spent active is statistically associated with diameter increase (mm) and percentage increase (adjusted for pre-stas diameter) in females (beta coefficient = 0,144; p=0,032 and beta-coefficient=0,135; p= 0,041, respectively) but not in males. Time spent sedentary did not show any associations with the flow-mediated dilatation variables in neither females nor males.

In conclusion, already in young adulthood, an active lifestyle is associated with higher flow-mediated dilatation as a measure of endothelial function.
