Abstract
- Background: Initial findings from the Dietary Approaches to Stop Hypertension (DASH)-Sodium Trial demonstrated that reduction of sodium intake in two different diets decreased blood pressure in participants with and without hypertension. Objective: To determine effects on blood pressure of reduced sodium intake and the DASH diet in additional subgroups. Design: Randomized feeding study. Setting: Four clinical centers and a coordinating center. Participants: 412 adults with untreated systolic blood pressure of 120 to 160 mm Hg and diastolic blood pressure of 80 to 95 mm Hg. Intervention: Participants followed the DASH diet or a control (typical U.S.) diet for three consecutive 30-day feeding periods, during which sodium intake (50, 100, and 150 mmol/d at 2100 kcal) varied according to a randomly assigned sequence. Body weight was maintained. Measurements: Systolic and diastolic blood pressure. Results: In all subgroups, the DASH diet and reduced sodium intake were each associated with significant decreases in blood pressure; these two factors combined produced the greatest reductions. Among nonhypertensive participants who received the control diet, lower (vs. higher) sodium intake decreased blood pressure by 7.0/3.8 mm Hg in those older than 45 years of age (P Conclusion: The DASH diet plus reduce sodium intake is recommended to control blood pressure in diverse subgroups.
