After 4 years a coronary heart disease risk factor intervention programme produced equally large and significantly reduced risk profiles in two intervention towns compared with a control town.
Intervention effects through community participation were assessed after cessation of the active intervention programme.
The impact of secular trends was assessed in the control town and in two previously unstudied towns.
Cross-sectional surveys were done in a random sample of 1620 participants aged 15-64 years in the three original towns 12 years after the initial quasi-experimental study.
Two years later 327 subjects, aged 35-44 years, were studied in the original control town and in two non-intervention towns.
Risk factor knowledge, smoking and medical histories were determined by questionnaire.
Blood pressure, anthropometry and blood lipids were recorded.
Data were compared across towns, and with previous surveys.
At 12 years the low intensity intervention town maintained a significantly better risk factor profile than the control town, while the high intensity intervention town now matched the control town.
No differences in risk factor profiles were found between the control town and the two new towns.
Deaths from coronary heart disease and strokes showed a downward trend in the study area. (...)
