Moderate Correlation Between High Salt Taste Preference and High Sodium Intake

Abstract

Background: High sodium intake daily can change human salt taste preference. High salt taste preferences will makes a person consumes excessive salt that contain sodium. Sodium will be removed from the human body through urine. Thus, the sodium intake can be calculated from urinary sodium level. The objectives of this study is to identify the correlation between salt taste threshold and urinary sodium level using predicted 24 hour urinary sodium level. Methods: The research design was analytical study and the research methods was correlation study. Samples for this study were obtained from epidemiology of hypertension and albuminuria in jatinangor community research with randomized sampling technique. Among 294 subjects, 111 were included and 183 were excluded. This study was conducted in Cipacing village, Jatinangor subdistrict during September-November 2014. Data were analyzed with Spearman Correlation statistical analysis with p value < 0,01. Result: Among 111 samples, most of them had high urinary sodium excretion. Spearman correlation test showed that correlation between salt taste threshold and predicted 24HUNa are statistically significant r = 0,597 (p < 0,01) for recognition threshold dan r = 0,407 (p < 0,01) for absolute threshold. Conclusion: There is moderate correlation of salt taste threshold and urinary sodium excretion.
