Box 44.9A Comprehensive Intervention Approach in South Africa

The Coronary Risk Factor Study in South Africa (Rossouw and others 1993) tested community interventions at different levels of intensity in two communities with a third control community. The target population was Caucasian South Africans. Interventions included direct media campaigns, public health messages delivered in a variety of ways, and home mailings. Also included were community activities, such as fun walks, public meetings, involvement of community-based organizations, free screening for blood pressure, small-group personal interventions, and encouragement of food substitution in stores and restaurants. The results showed an improvement in the community risk factor profile for CAD in the intervention communities, especially in relation to blood pressure, smoking, and overall risk. The results indicate no additional benefit of the personal intervention for high-risk individuals beyond that already offered by the mass media program. Estimated per capita costs of the heavy intervention program were roughly four times as much as for the mild intervention program (US$22 per capita compared with US$5 per capita), and the low-intervention community received almost the same level of benefits as the high-intervention community.
