[Clinical characteristics of patients with essential hypertension regarding salt intake].
A number of epidemiologic and experimental studies have revealed the close relationship between salt intake and blood pressure. The objective of this study was to know the salt intake among 293 not previously treated hypertensive patients and to identify their clinical characteristics that would allow us to define the profile of patients with high sodium intake. Hypertensive patients who first attended a specialized high blood pressure (HBP) clinic not previously treated with drugs, at least for the last month were selected. Sodium 24 h urinary excretion was determined on two occasions, as sodium intake index. Thirteen percent of patients had a salt intake lower than 100 mEq/24 h and 35% of patients higher than 200 mEq/24 h. Sodium intake was higher among men, younger patients, those with a higher Quetelet index, smokers, higher socioeconomic status, and less years with IBP. No differences were observed between salt intake among hypertensive patients with associated diabetes or hyperlipidemia. The Quetelet index, sex, age and smoking were identified as independent variables for salt intake by the multiple linear regression analysis. No correlation was found between salt intake and blood pressure. In conclusion, a high sodium intake was observed in our setting among hypertensive patients who had previously been advised to moderate salt intake. The highest salt intake was observed among men, youths, obese and smokers.
