Abstract

Abstract : Objective: Salt-taste threshold can influence salt appetite, and is thought to be another marker of sodium intake. Many studies mentioned the relationship between sodium intake and blood pressure. The aim of this study was to evaluate the relationship the salt-taste threshold and urinary sodium excretion between normotension and hypertension. Design and Method: We enrolled 172 patients (mean age 52 yrs, male 85 (49.4 %)), who was visited our clinic for further evaluation of high blood pressure. Hypertension was diagnosed as day time systolic/diastolic BP > 135/85mmHg by ambulatory BP monitoring. We compared the salt taste threshold assessed by graded solutions of saline and 24-hour urinary sodium excretion. Results: The salt-taste threshold was not significant between normotensive (51 patients (29.7%), mean age 53 years) and hypertensive patients (121 patients (70.3%), mean age 51 years)(6.6 ± 1.1 vs. 6.7 ± 1.2, respectively). The 24-hour urinary sodium excretion of hypertensive patients was significant higher than normontensive patients (143.8 ± 63.8 mg vs 120.0 ± 61.4 mg, respectively, P < 0.05). Also, the ration of urinary sodium-potassium was significantly higher in the hypertensive patients. However, there is no relationship between the salt-taste threshold and 24-hour urinary sodium excretion in the both groups. Conclusions: The salt-taste threshold might be not related to blood pressure status as well as urinary sodium excretion.
