ABSTRACT
ABSTRACT BACKGROUND:
Hypertension is an important public health problem. Overweight and high salt intake are risk factors for its development.OBJECTIVE:
To evaluate the association between salt taste sensitivity threshold (STST) and blood pressure (BP) in healthy adults. DESIGN ANDSETTING:
Cross-sectional study conducted in a private institution.METHODS:
104 healthy adults (aged 18-59 years) were evaluated. Sociodemographic, clinical and dietary data were collected. Nutritional status and BP were assessed using body mass index (BMI), waist circumference (WC), systolic blood pressure (SBP) and diastolic blood pressure (DBP). STST was assessed using graded saline solutions with sodium chloride concentrations ranging from 0.228 to 58.44 g/l. Identification of salty taste in solutions ≥ 3.652 g/l was used as the cutoff point for high STST.RESULTS:
Participants with high STST presented higher daily average intakes for energy (2017.4 ± 641.5 versus 1650.5 ± 357.7 kcal/day; P = 0.01) and sodium (3070.2 ± 1195.1 versus 2435.2 ± 963.6 mg/day; P = 0.01) and higher BMI (P = 0.008) and WC (P = 0.002). After adjustment for age, sex, sodium and potassium intake, WC and family history of hypertension, the averages for SBP and DBP in subjects with high STST were higher than in those with normal STST (SBP 138.2 ± 1.7 versus 119.7 ± 0.9 mmHg; P < 0.001; DBP 81.2 ± 1.9 versus 75.1 ± 1.0 mmHg; P = 0.008).CONCLUSION:
High STST was associated with elevated blood pressure in healthy adults, regardless of other risk factors for hypertension.
