[10 years' intervention in coronary risk factors in a rural community]

In 1977 a field survey of coronary risk factors was undertaken in a Tyrolean village. All inhabitants aged between 20 and 64 years were investigated for hyper-cholesterolaemia, hypertension and smoking. In subsequent years a community intervention programme was developed and implemented in a joint endeavour between the general practitioners of the village and the project leader. After 10 years, in May 1987, a new survey was conducted in the age group 20 to 74 years. The mean values for systolic and diastolic blood pressure as well as the plasma cholesterol level of the original cohort were found to be significantly lower than 10 years previously. There was a substantial, but not significant reduction in the percentage of male smokers in the age group 20 to 64 years, but no change in the percentage of female smokers.
