The Belgian Heart Disease Prevention Project: 10-year mortality follow-up.

The Belgian Heart Disease Prevention Project was a controlled, randomized multifactorial intervention trial in middle-aged men which lasted 6 years. Significant net differences between intervention and control groups were observed in change in risk profile, in total mortality and in CHD incidence. The net difference in risk profile change was greatest at two years, intermediate at four years and minimal at six years. Total and cause-specific mortality rates were systematically followed from the 6th to the 10th year. Follow-up at 10 years was 99.3% complete. The differences between intervention and control groups in total, coronary and cardiovascular mortality reduced from the 6th to the 10th year. The results suggest that changes in risk profile are rapidly followed by changes in cardiovascular mortality, but this applies in both directions. Thus risk reduction should be maintained in order to achieve a long-lasting preventive effect.

Belgian heart disease prevention project: incidence and mortality results.

Results are presented from the Belgian Heart Disease Prevention Project, part of the WHO European Collaborative Trial in the Multifactorial Prevention of Coronary Heart Disease (CHD). 19 409 men aged 40-59 yr took part; they were employed in thirty factories which formed the allocation units for a randomised controlled trial lasting 5-6 yr. The intervention package consisted largely of health education promoting a cholesterol-lowering diet, smoking cessation, weight control, physical activity, and treatment of arterial hypertension. A programme of information was supplemented by face-to-face counselling at the workplace by two physicians attached to the project. The coronary risk profile was reduced in the intervention group, compared with that in the control group, especially during the first 4 yr, by effects on serum cholesterol, number of cigarettes smoked daily, and arterial blood-pressure. Total mortality was 17.5% lower in the intervention group than in the control group (p = 0.038). Coronary mortality was reduced by a non-significant 20.8% whereas CHD incidence (non-fatal myocardial infarction plus fatal myocardial infarction plus sudden deaths) was reduced by 24.5% (p = 0.031). Non-fatal myocardial infarction (not a major end-point) was similarly reduced by 26.1% (p = 0.030).

[Geographic pathology of cardiovascular diseases in Belgium (author's transl)].

The association in many populations of the fat content of the diet and frequency of ischemic heart disease is mentioned. The author gives a summary of papers showing on one hand, a high correlation between the content of the diet in saturated fatty acids and ischemic heart disease morbidity and mortality rates, and, on the other hand, the protective effect of a change towards more polyunsaturated fatty acids in the diet. Several teams of Belgian researchers have recently published new facts on this matter. In the Northern Flemish speaking part of the country, saturated fatty acids have been partially replaced by polyunsaturated fatty acids from vegetable sources. This change has been followed by a general decrease of ischemic heart disease incidence, prevalence and mortality rates. In the Southern French speaking part of the country, the alimentary changes have not occurred so far; the ischemic heart disease morbidity and mortality rates stand higher.

The pattern of food and mortality in Belgium.

Belgians have been gradually shifting from a low ratio of polyunsaturated/saturated fat in their food to a higher one with lower total fat and cholesterol. This has occurred predominantly in the north, where the most obvious change is a decrease in butter consumption and an increase in margarine consumption. The northerners have a four to five times smaller intake of butter than the southerners and nearly double the intake of margarine. Evidence gathered over the past ten years reveals in the north a decreasing serum-cholesterol and in the south a significantly higher serum-cholesterol, associated with higher coronary morbidity and mortality. Life expectancy of males in the north is 2-4 years higher at birth and 2-2 years higher at the age of 30. It is concluded that the food habits of a population can be changed, with great benefit.
