DIET AS A RISK FACTOR FOR PERIPHERAL ARTERIAL-DISEASE IN THE GENERAL-POPULATION - THE EDINBURGH-ARTERY-STUDY

The Edinburgh Artery Study included a cross-sectional survey of 1592 men and women (aged 55-74 y). One aim was to examine relationships between an indicator of peripheral arterial disease, the ankle brachial pressure index (ABPI), and dietary factors. Nutrient intake was derived from a food-frequency questionnaire. Higher frequency of consumption of fiber-containing foods was associated with greater mean ABPI in males and higher consumption of meat and meat products were significantly associated with low mean ABPI in males and females. In a multiple linear regression with ABPI as outcome and energy-adjusted nutrients as predictors, cereal fiber (P = 0.02) and alcohol (P = 0.04) were positively associated with the ABPI in, males but not in females. Dietary vitamin E(alpha-tocopherol) intake was positively associated with ABPI (P = 0.04) independently of smoking and other nutrients. Dietary vitamin C intake was significantly related to ABPI (P = 0.006) only among those who had ever smoked.
