Lessons Learnt from Finnish experiences on NCD Prevention and Control Erkki Vartiainen, MD, Professor, Assistant Director General 07/05/2018 Erkki Vartiainen 1
START OF THE NORTH KARELIA PROJECT (1) Seven countries study in North Karelia Since 1955 Public attention to the high CVD mortality and to the statistics that the province of North Karelia is in the worse 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
Two main questions in 1970’s Can risk factors and behaviors be changed on population level ? If risk factors will reduce what will happen to the mortality?
North Karelia Project AIMS OF THE NORTH KARELIA PROJECT MAIN OBJECTIVE: - Initially: To reduce the CVD mortality - Later: To reduce major chronic disease mortality and promote health INTERMEDIATE OBJECTIVES: - To reduce the population levels of main risk factors, emphasizing lifestyle changes and to promote secondary prevention NATIONAL OBJECTIVE: - Initially: To be pilot for all Finland - Later: To be demonstration and model program
North Karelia Project HIERARCHY OF OBJECTIVES. GENERAL GOAL: North Karelia Project HIERARCHY OF OBJECTIVES GENERAL GOAL: Improved health MAIN OBJECTIVES: Medical /Epidemiological Prevention of chronic framework: diseases & promotion of health - earlier research - local prevalence INTERMEDIATE OBJECTIVES: Risk factors, life-styles and treatment Social / Behavioural framework: - theory PRACTICAL OBJECTIVES: - community analysis Intervention programme
FROM KARELIA TO NATIONAL ACTION First province of North Karelia as a pilot (5 years), then national action Good scientific evaluation to learn of the experience
25 % 5 % 70 % Theoretical presentation of the difference between People with low risk factor level People with average risk factor level People with clinically high 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
North Karelia Project THEORETICAL PRINCIPLES OF THE INTERVENTIONS MEDICAL FRAMEWORK: - Primary prevention - Main targets: smoking, diet, cholesterol, blood pressure - popupation approach, general risk factor reduction emphasizing lifestyle changes SOCIAL / BEHAVIOURAL FRAMEWORK - Social marketing - Behaviour modification - Communication - Innovation - diffusion - Community organization
North Karelia Project PRACTICAL 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, massmedia, campaigns) 2. Preventive services (primary health care etc.) 3. Training of professional and other workers 4. Environmental changes (smokefree areas, supermarkets, food industry etc.) 5. Monitoring and feed-back

CONSTRAINTS Suspicions from the cardiological scientific community 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 highly valued culturally 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
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
MAJOR ELEMENTS OF SUCCESSFUL NATIONAL PREVENTIVE PROGRAM 1 RESEARCH HEALTH SERVICES (ESPECIALLY PRIMARY HEALTH CARE) HEALTH EDUCATION PROGRAMMES (COALITIONS, NGO’S, COLLABORATION WITH MEDIA ETC.) SCHOOLS, EDUCATIONAL INSTITUTIONS INDUSTRY, BUSINESS
MAJOR ELEMENTS OF SUCCESSFUL NATIONAL PREVENTIVE PROGRAM 2 NATIONAL DEMONSTRATION PROGRAMME(S), FOCAL POINT(S) POLICY DECISIONS, INTERSECTORAL COLLABORATION, LEGISLATION MONITORING SYSTEM INTERNATIONAL COLLABORATION
NORTH KARELIA HAS SHOWN Prevention of major chronic diseases is possible and pays off Population based prevention is a 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) Many results of prevention occur surprisingly quickly (CVD, diabetes) and also at relatively late age At the same time increases in subjective health and physical capacity
North Karelia Project CONCLUSIONS A comprehensive, determined and theory-based community program can have a meaningful positive effect on risk factors and life styles Such changes are associated with respective favourable changes in chronic disease rates and health of the population A major national demonstration program can be a strong tool for favourable national development in chronic disease prevention and health promotion
