Abstract

Hypertension is an important public health issue globally. In Brazil, according to the 2019 National Health Survey, it is estimated that about 23.9% of the adult population is diagnosed with arterial hypertension. Sodium consumption above 2000 mg/day, or 5 g/day of salt, is an aspect related to increase in blood pressure, and can be easily modified. However, it is difficult to know the actual consumption in clinical care, since dietary surveys seem to underestimate the actual sodium intake. Thus, a cross-sectional study will be carried out to compare self-reported sodium intake with intake evidenced by 24-hour urinary excretion and to evaluate the relationship between estimated sodium intake and blood pressure in obese adult patients (BMI equal to or greater than 30 kg/m2) of both sexes attended at the Ambulatório de Nutrologia of the Hospital das Clínicas, Faculdade de Medicina de Ribeirão Preto, University of São Paulo.
