Description
Summary:The Coronary Risk Factor Study (CORIS) examined the feasibility and effectiveness of a muitifactonal community in tervention programme to reduce coronary heart disease (CHD) risk factor levels. Three Afrikaner communities were surveyed before and after a 4-year Intervention in two of the communities, the third serving as a control (C). Inter vention was primarily by small mess media (low-intensity intervention, LII) or by small mass media plus interpersonal in tervention to high-risk individuals (high-intensity intervention, HII). After allowing for change in C, significant net reductions in blood pressure, smoking, and risk score were obtained in LII and HIl alike. Though the total cholesterol (TC) fell by 10–12%, there was no net reduction in favour of the intervention communities. However, LII and HII resulted in significant increases in high-density lipoprotein cholesterol (HDL-C) levels and HDL-C/TC ratios in com parison to C. Overall, the LII community fared almost as well as the HII community, and high-risk individuals did not show a greater change in risk factors than others. We conclude that community-based intervention works, end that in these particular communities a media-based health education programme was more cost-effective than one which adds a greater degree of interpersonal intervention.
