The purpose of this study was to identify the best of three methods of treating hypertensive outpatients in order to minimize dietary sodium levels and thereby decrease the need for antihypertensive drugs. Forty-eight outpatients with hypertension were randomly assigned to three treatment programs: (1) advice; (2) an intensive educational program; and (3) small-group management plus feedback. This last program had a problem-solving format in which patients shared ideas and provided mutual support for dietary change. Only these group management patients were told the results of their sodium determinations. In a one-year study, group management plus the feedback to patients of information on the sodium content of their urine was more effective in decreasing dietary sodium intake than advice or an intensive educational effort.
