Abstract

This study aimed at analyzing the alimentary habits of treated hypertensive patients identifying the degree of concordance with Dietary Approaches to Stop Hypertension (DASH) plan. Anthropometry and blood pressure (BP) were evaluated, and the 10-year risk for general cardiovascular disease was estimated and used to calculate vascular age. A DASH concordance score was obtained using food frequency questionnaire and the cut-off points were established for eight food groups. Subjects were divided into two groups according to the median of DASH concordance score: lower concordance (LC group < 4.5 points, ) and higher concordance (HC group ≥ 4.5 points, ). LC group was associated with higher BP, vascular age, and cardiovascular risk. DASH concordance score was positively correlated with intake of fiber, calcium, potassium, and magnesium ( ) and negatively correlated with BP, cardiovascular risk, and vascular age ( ). After logistic regression adjusted for age and gender, only cardiovascular risk ( , ) was independently associated with DASH concordance score. Hypertensive patients with dietary patterns less concordant with the DASH plan had higher BP levels and increased cardiovascular risk, indicating the relevance of management in the treatment of these patients.
