The Trial of Antihypertensive Interventions and Management (TAIM) was a multicenter randomized drug (double-blind, placebo-controlled)-diet trial. One objective of TAIM was to assess the long-term ability of a low-sodium/high-potassium (Na+ decreases/K+ increases) diet to maintain blood pressure control in persons at 110% to 160% ideal weight with diastolic blood pressure from 90 to 100 mm Hg who were on no drugs or on low-dose monotherapy. Participants, 56% men and 33% black, were randomized to usual diet (n = 296) or to Na+ decreases/K+ increases diet (n = 291) and within each diet group to placebo, 25 mg/day chlorthalidone, or 50 mg/day atenolol.

Background: Increasing concern over long-term drug treatment of mild hypertension has stimulated several studies of weight reduction. Phase I of the Trial of Antihypertensive Interventions and Management demonstrated a short-term effect of weight loss on blood pressure control in overweight persons with mild hypertension, who were either taking placebo or taking low-dose monotherapy. Phase II investigates the long-term benefit of weight loss on the ability to maintain blood pressure control.

The Trial of Antihypertensive Intervention and Management evaluated nine diet-drug combinations in 878 mildly hypertensive, moderately obese participants using a 3 x 3 factorial design. Drugs evaluated were placebo, diuretic (chlorthalidone), and beta-blocker (atenolol); diets were usual (no intervention), weight reduction, and low sodium/high potassium (Na/K). This article reports 6-month dietary changes and the effect of dietary change on blood pressure.
