Ninety-three overweight adult males with labile blood pressure elevation participated in a 20-week dietary intervention program to achieve a 10 per cent reduction in body weight and a reduction in dietary sodium intake to 70 milliequivalents per day. By random assignment, half were treated with intensive group treatment procedures and half with individual counseling. Written handouts and assignments were identical, as was the schedule of treatment visits. Both techniques produced significant decreases in weight, sodium intake, calorie intake, and blood pressure. Calorie and sodium knowledge also increased significantly with both intervention approaches. The two treatment modalities did not differ in effectiveness.
93名血压波动升高的超重成年男性参加了一项为期20周的饮食干预计划，以实现体重减轻10%，并将每日饮食钠摄入量减少至70毫当量。通过随机分配，一半接受强化小组治疗程序，另一半接受个体咨询。书面资料和作业相同，治疗就诊时间表也相同。两种方法都使体重、钠摄入量、卡路里摄入量和血压显著下降。两种干预方法都使卡路里和钠知识显著增加。两种治疗方式的效果没有差异。
