Theoretical rationale of community intervention for the prevention and control of cardiovascular disease.
Cardiovascular disease is the leading cause of death and disability in the developed world, accounting for slightly more than 40% of all mortality. Along with the resultant disability of those who survive with the disease it costs the health care system in Canada approximately $17 billion on an annual basis. The known risk factors for cardiovascular disease are widespread within the population; in Canada, approximately 70% of individuals have one or more of the major risk factors. Research over the past 25 years has disclosed that a significant proportion of the cause of heart disease and its risk factors are rooted in the unhealthy habits of average living in conjunction with unfavorable physical, economic and psychosocial environments. The primary prevention of cardiovascular disease has focused on individual risk factor change combined with approaches to community organization in an effort to produce a more conducive environment for behavior change to be carried out. First-generation community programs for cardiovascular disease prevention, as illustrated by the North Karelia Project, Stanford Five City Project and others in the United States, have relied heavily on social learning theory as advanced by Bandura, from Stanford University. Second-generation prevention programs, such as the Nova Scotia Heart Health Program, have relied on these theories as well as theories of participation and community development in the prevention of major noncommunicable diseases. This paper gives an overview of the theoretical basis of community intervention programs for cardiovascular disease. Included will be a discussion of some of the various theoretical approaches used in Canada and the United States and elsewhere over the past 25 years.
