Association between alcohol consumption and subclinical carotid atherosclerosis : The study of health in Pomerania

Epidemiologic studies have shown a J-shaped association between alcohol consumption and vascular diseases. However, only few studies have reported on the association between alcohol intake and subclinical atherosclerosis. The aim of the study was to investigate the relation between alcohol intake and carotid intima-media thickness (IMT) in participants of the population-based Study of Health in Pomerania. In 1230 men and 1190 women, the mean IMT of the right and left common carotid arteries was measured by B-mode ultrasonography. Alcohol consumption was assessed with a computer-assisted face-to-face interview. In men, carotid IMT as a function of alcohol intake was depicted as a J-shaped curve with a nadir for the alcohol intake category of 61 to 80 g/d. Linear regression models controlled for age, diabetes, systolic blood pressure, leisure time physical activity, food frequency patterns, smoking status, and education revealed a significant inverse association between IMT and alcohol intake < or =80 g/d in men (beta=-0.009, P
