Blood Pressure Reduction by Change in Life Style. The CVD Intervention Study in Glostrup

In a controlled, primary intervention, cardiovascular survey on 928 men and women aged exactly 30, 40, 50 & 60 years, a significant reduction (about 5 mmHg) was found in systolic blood pressure mean difference before and after intervention between the intervention- and control group. The observation time was 7 months. Most of the twentynine drop outs were excluded for personal reasons or because of antihypertensive treatment. A reasonable explanation for the blood pressure reduction is a change in life style, in the intervention group. The subjects in the intervention group increased physical activity and decreased fat and salt intake in contrast to the control group (p less than 0.001, 0.005).
