Public health development in Finland after the World War II Before the War • Mainly Infectious Diseases Long, heavy war and difficult post war years • The country was very poor In the 1950’s and 60’s • Rapid increase in the CVD and other NCD rates • Public health response mainly building hospitals and health services
In the 1970’s • Statistics showed very bad public health situation • CHD mortality rates among men highest in the world • Short life expectancy • Increasing public discussion • General opinion related CHD to stress, ageing and genetics • It was earlier also referred to as “Disease of the Executives” • Cardiologists were aware that there are numerous “Statistical Associations”
Start of the North Karelia project • North Karelia was part of the Seven Countries Study since 1955 • Public attention to the high CVD mortality and to the statistics showing that the province of North Karelia was in the worst situation • Petition by the representatives of people in North Karelia for national assistance to cope with the problem (January 1971) • Delegation led by the Governor to Helsinki, the petition was handed to the Prime Minister and other decision makers • Involvement of Finnish experts and WHO
North Karelia ProjectPrinciples for Defining the Intermediate Objectives • Due to the chronic nature of CVD, the potential for the control of the problem lies in primary prevention• The risk factors were chosen on the basis ofbest available knowledge: - previous studies - collective international recommendations - epidemiological situation in North Karelia• Chosen risk factors: - smoking - elevated serum cholesterol (diet) - elevated blood pressure
Serum cholesterol distribution in Finland and Japan in 1970’s Frequency % mmol/l
Main Principles of the North Karelia Project • Prevention is the only sustainable public health approach • Risk factors identified by prospective studies, closely linked with certain behaviours - deeply enrooted in the community • Community based preventive programme 1 Target: the community (not individuals) 2 Intervention: through community structures (not external intervention) • Emphasis on community organization, general community changes
CLINICAL INTERVENTION RISK FACTORS PUBLIC HEALTH INTERVENTION
25 % 5 % 70 % People with average risk factor level People with clinically high risk factor level People with low risk factor level Individual risk of CHD Distribution of people according to risk factor level Theoretical presentation of the difference between individual risk and the proportional attributable risk
Constraints • Suspicions from the scientific community of cardiologists • Medical knowledge on prevention questionable, community prevention new concept • North Karelia socially deprived area, poor and with many social problems (unemployment, migration, shortage of doctors etc) • War and post war years: Great poverty, after that increase in consumption • Dairy farming main agriculture: Butter and animal fat culturally highly valued • Strong commercial pressures (“FAT WAR”), supported by political pressures • Raising the funding (intervention and evaluation research) • To maintain interest and funding over decades
Advantages • Magnitude of problem, concern of people • Relatively homogenous population, traditions of community action • Trust in experts and in public action • Good information system • Good collaboration with people • Good leadership

North Karelia ProjectPractical intervention • Emphasis on persuasion, practical skills, social & environmental support for change • Research team & local project office with comprehensive community involvement • Main areas: 1. Media activities (materials, mass media, campaigns) 2. Preventive services (primary health care etc.) 3. Training of professional and other workers 4. Environmental changes (smoke-free areas, supermarkets, food industry etc.) 5. Monitoring and feed-back

Finland Has Shown • Prevention of major chronic diseases is possible and pays off • Population based prevention is the only cost effective and sustainable public health approach to chronic disease control • Prevention calls for simple changes in some lifestyles (individual, family, community, national and global level action) • Influencing lifestyles is a key issue • Many results of prevention occur surprisingly quickly (CVD, diabetes) and also at relatively late age • Comprehensive action, broad collaboration with dedicated leadership and strong government policy support are crucial
Why success in North Karelia • Appropriate epidemiological and behavioural framework • Restricted, well defined targets • Good monitoring of immediate targets (Behaviours, process) • Flexible intervention • Emphasis in changing environment and social norms • Working closely with the community • Positive feedback, work with media • International collaboration, support from WHO • Close interaction with national health policy, integration with National Public Health Institute • Long term, dedicated leadership
