title: Effect of Intensive Salt-Restriction Education on Clinic, Home, and Ambulatory Blood Pressure Levels in Treated Hypertensive Patients During a 3-Month Education Period.
abstract: The authors tested the hypothesis that low-salt diet education by nutritionists would lower blood pressure (BP) levels in treated hypertensive patients. The amount of urinary salt excretion and clinic, home, and ambulatory BP values at baseline and at 3 months were measured in 95 patients with hypertension. After randomization to a nutritional education group (E group, n=51) or a control group (C group, n=44), the C group received conventional salt-restriction education and the E group received intensive nutritional education aimed at salt restriction to 6 g/d by nutritionists. From baseline to the end of the study, 24-hour urinary sodium excretion was significantly lowered in the E group compared with the C group (6.8±2.9 g/24 h vs 8.6±3.4 g/24 h, P<.01). Morning home systolic BP tended to be lowered in the E group (P=.051), and ambulatory 24-hour systolic BP was significantly lowered in the E group (-4.5±1.3 mm Hg) compared with the C group (2.8±1.3 mm Hg, P<.001). Intensive nutritional education by nutritionists was shown to be effective in lowering BP in treated hypertensive patients.
