North Karelia Project

A community-based cardiovascular disease prevention project launched in 1972 in the North Karelia region of Finland, following local petitions over the region's extremely high rate of premature deaths from heart disease among working-age men. Run by Finnish public health authorities with involvement from the World Health Organization, it combined mass media campaigns and community organizing on diet, smoking and blood cholesterol with health-system changes such as training primary care staff in risk-factor counseling and working with local food producers to promote lower-fat dairy and more vegetable production. It is widely regarded as a landmark demonstration that a whole-community, multi-sector intervention could shift population health behavior, and its methods were gradually extended nationally across Finland; North Karelia's cardiovascular mortality among working-age men fell by roughly 80 percent over the following decades, a decline researchers attribute substantially to the project's approach combined with broader long-term dietary change.
