Sponsor's own description

Hypertension is one of the most common chronic medical conditions. The concerned sequelae are the cardiovascular complications, especially acute myocardial infarction and stroke. In Thailand, the incidence of hypertension is increasing each year. Many clinical studies found that salt intake over the reference level (\>5 g/day) would result in elevated blood pressure (BP) and long-term morbidity. Dietary salt reduction campaigns were unsuccessful, in part, due to time limitation in the clinic, lacking of awareness, and the higher threshold to detect salt taste in chronic high salt ingestion. Salt meter is a device used to detect sodium content in daily food. It will facilitate monitoring and control of salt intake. The 24-hour urinary sodium excretion is an acceptable method to reflect the quantity of sodium intake. This study aimed to compare the efficacy of salt meter plus dietary education compared with education alone in terms of salt intake reduction, blood pressure, salt taste sensitivity, and vascular consequence.
