Impact of self-monitoring of salt intake by salt meter in hypertensive patients: A randomized controlled trial (SMAL-SALT).

ABSTRACT: Salt intake over reference level would result in elevated blood pressure (BP) and long-term morbidity. Salt meter is a device used to detect sodium content in daily food. This study aimed to evaluate the efficacy of salt-meter addition to dietary education. The authors conducted a randomized-controlled trial in hypertensive patients with uncontrolled BP (systolic BP ≥140 mmHg or diastolic BP ≥90 mmHg). Patients were randomized to receive salt meter plus dietary education (group A) or education only (group B), and followed up for 8 weeks. The primary endpoint was change in 24-h urinary sodium excretion. Changes in BP, salt taste sensitivity, cardio-ankle vascular index (CAVI) were also analyzed. There were total number of 90 patients who had complete follow-up, 45 in each group. Mean age wa
