Peripheral Arterial Disease (PAD) is most prevalent in the elderly and associated with increased cardio vascular disease (CVD) morbidity and mortality. Treatment focuses on improving functional capacity and reducing CVD risk factors. To date, little is understood about dietary habits and weight in this patient population. Nutritional and weight recommendations are based on heart health, and little is known about the unique needs of elderly PAD patients with multiple comorbidities. This prospective study compared 1) the dietary intake of nonobese PAD patients in comparison with those who were obese and; 2) dietary intake of those patients with the Estimated Average Requirement (EAR) based on age, gender and BMI. Nutritional intake was assessed with the Block 98 Food Frequency Questionnaire. Body mass index (BMI) was calculated in accordance with the National Heart, Lung, and Blood Institute (NHLBI) guidelines.The study population was divided into obese (BMI ≥ 30) and nonobese (NO) groups. Comparisons between groups were performed using the Mann-Whitney U test for continuous variables and the Chi-square test for ordinal variables. All tests were two-tailed and P < 0.05 was considered significant. The Estimated Average Requirement (EAR) cut-point method was used to compare nutritional variables with Dietary Reference Intakes (DRI). The study population included 189 NO (BMI < 30) and 111 obese (BMI > 30) individuals. Obese participants reported greater intake of foods containing cholesterol and trans-fatty acids and more frequent intake of B vitamins in comparison with the NO BMI group. Additionally, the nutrient intake of all participants by age, gender and BMI was lower than the EAR for magnesium, folate, and Vitamin E. These results suggest that the nutritional intake of PAD patients differs based on gender and BMI. Additionally, EAR was lower for specific nutrients than recommended. Further investigation is needed to examine the association between nutritional intake and nutrition-related deficits.
