Intervenção Nutricional melhora qualidade da dieta e reduz glicemia em pacientes com aterosclerose manifesta

Abstract

Study with the objective of evaluating the impact of a nutritional intervention program on the quality of the diet and on the cardiometabolic markers of patients with a previous history of atherosclerosis. This is a randomized clinical trial lasting 36 months, a sub-study of a multicenter project. The intervention group received the Brazilian Cardioprotective Diet (DICABr) and the control was submitted to conventional nutritional guidelines according to current guidelines. The groups were monitored every 6 months by nutritionists and anthropometric, biochemical, food consumption and blood pressure data were collected. Adherence to the diet was assessed by calculating the index of adequacy to the DICABr diet and the impact of the intervention by comparing the components of the metabolic syndrome after 36 months. The sample consisted of 50 participants, mean age 61 ± 8.26 years and 68% had metabolic syndrome initially. After 36 months, there was an improvement in the DICABr index in the intervention group (p = 0.024) and a reduction in the percentage of participants with high blood glucose when compared to the control group (p = 0.030). There was no change in anthropometric data, lipid and blood pressure profile after 36 months in any of the 2 groups.
