Abstract

Black and White patients from a VA Medical Center hypertension clinic serving a rural, elderly population were randomly assigned to one of three interventions : a) one session of individualized instruction for 87 mmol/day reduced sodium diet; b) one session of 87 mmol/day reduced sodium diet instruction plus a means of estimating urine electrolyte excretion at home; or c) instructions to maintain the usual diet until reevaluated (control). At 3-month follow-up, reduction in 24-hour urine sodium excretion was significantly greater in participants receiving dietary instructions with feedback than in controls. White participants with access to feedback had the greatest reduction in urine sodium. Results support the feasibility of significant sodium reduction in hypertensive patients following a single intervention session.
