Lessons Learnt from Finnish Experiences on NCD Prevention and Control Erkki Vartiainen, MD, Professor, Assistant Director General Erkki Vartiainen
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?
Aims of the North Karelia Project 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:Improved health MAIN OBJECTIVES:Prevention of chronicdiseases & promotion of health Medical / Epidemiologicalframework:- earlier research- local prevalence INTERMEDIATE OBJECTIVES: Risk factors, life-styles and treatment Social / Behavioural framework:- theory- community analysis PRACTICAL OBJECTIVES: 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 % 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
II. BEHAVIOUR MODIFICATION (Puska and McAlister)
Theoretical principles of the interventions North Karelia Project • Medical framework: • Primary prevention • Main targets: smoking, diet, cholesterol, blood pressure • Population approach, general risk factor reduction emphasizing lifestyle changes • Social / Behavioural framework • Social marketing • Behaviour modification • Communication • Innovation – diffusion • Community organization
Practical intervention North Karelia Project • 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
Evaluation North Karelia Project Evaluation tasks • Feasibility, performance • Effects: risk factors, lifestyles,disease rates, mortality • Change process • Costs • Other consequencies Evaluation types • summative: 5-year periods • formative, internal evaluation
Smoking control programmes • Voluntary restrictions of smoking in public places • Mass media • Voluntary restrictions in advertising • Use of opinion leaders • Training of health care personnel • Cessation services in health centres
Hypertension register • Computer based • Hypertension clinic • Nurses in a key position • Invitation letter once a year

Setting strategy • Schools • Work site • Media • Family • Health centers/hospitals • Villages
Use of lay opinion leaders to promote health innovations in community • Innovation-diffusion theory • Training seminars in municipalities • Discuss health issues in normal life • 805 persons participated • Recruiting by local people and Heart Association • 1975-1982 • Evaluation in 1982: 399 (50%) still active
A comprehensive television smoking cessation programme in Finland • Voluntary smokers in TV studio tried to stop smoking • 6 sessions + 2 follow-up sessions • Intensified filed activity in North Karelia • 250 000 at least 4 sessions • 30 000 attempt to quit • 20 000 quit • 10 000 remained non-smokers

Percentage of weekly smokers (Baseline smokers excluded) Program effect1 8th OR = 0.47 (0.30-0.71) 51% 9th OR = 0.68 (0.51-0.89) 28% The OR for weekly smoking for experimental school compared to control school pupils
