Declining trends in incidence, case-fatality and mortality of stroke in three geographic areas of Finland during 1983-1989. Results from the FINMONICA stroke register.

Stroke mortality has decreased during the last decade in many industrialized countries, but there has been no clear evidence for a decline in the incidence of stroke. The present study analyzes the trends in the incidence, mortality and case-fatality of stroke in Finland from 1983 to 1989. We used data from the FINMONICA stroke register, a community based register collecting information on all suspected stroke cases aged 25-74 in three geographical areas of Finland. Annual attack rate, incidence, mortality and case-fatality rates were calculated for all strokes and for different subcategories of stroke. A linear regression model was applied to calculate the yearly trends of these rates. In men, the attack rate of stroke was 336/100,000 in 1983 and 310/100,000 in 1989 (-8% during the observation period); incidence declined from 269/100,000 in 1983 to 236/100,000 in 1989 (-12%); mortality declined from 82/100,000 to 64/100,000 (-22%), and case-fatality declined from 25% to 21% (-18%). Also among women similar declining trends were observed (-11%, -13%, -16%, and -10% respectively), but they were not statistically significant. In both incidence and mortality of stroke, the decline was seen in all age groups. Incidence and mortality of cerebral infarction declined similarly to all strokes. A large fall in the incidence (-24% in both men and women) and mortality (-38% in men and -27% in women) of subarachnoid haemorrhage was also observed. An increasing trend, although not significant, was instead observed for cerebral haemorrhage. First stroke and especially first cerebral infarction contributed most to the decline in case-fatality. The availability of computerized brain tomography improved from 18% in 1983 to 60% in 1989. We observed a fall in the incidence, mortality, and case-fatality of stroke during 1983-1989. Among the subtypes of stroke, cerebral infarction contributed most to the decline, but the data suggested also a declining trend in the incidence and mortality of subarachnoid haemorrhage, observed now for the first time in Finland since the 1960s. The fall in the incidence of stroke was not as steep during the 1980s as it was during the 1970s; Finland is anyhow the only European country which has reported a decreasing trend in stroke incidence during the 1980s. We need now to investigate how much the decline in the classical risk factors for stroke observed in Finland during the last two decades predicts the observed trends.

Comparison of diets of diabetic and non-diabetic elderly men in Finland, The Netherlands and Italy.

OBJECTIVE: To evaluate whether dietary recommendations for subjects with diabetes are met among Finnish, Dutch and Italian elderly men with diabetes, and whether the diets of diabetic and non-diabetic men differ in these three countries. DESIGN: A dietary survey using cross-check dietary history method. A cross-sectional comparison. SETTING: Thirty-year follow-up of survivors from the Finnish, Dutch and Italian cohorts of the Seven Countries Study. SUBJECTS: 227 elderly men from Finland, 537 from The Netherlands, and 417 from Italy, of whom 8-9% had diabetes. MAIN RESULTS: The diets of non-diabetic men from the three countries differed markedly from each other. In all three countries diabetic men consumed less added sugar than non-diabetic men. In Italy, in addition, diabetic men consumed more fruits and berries and vegetables. The Dutch diabetic men ate relatively more cereal products, fruits and berries, milk and milk products, cheese, and meat and meat products and drank less alcoholic beverages than non-diabetic men. The diet of both diabetic and non-diabetic Finnish and Dutch men was characterized by high fat content (41% and 40% of energy, respectively). The fat content of the diet was even higher for diabetic than non-diabetic men in Finland and The Netherlands, but not in Italy. The fibre content of the diet was the highest among Dutch men and diabetic men received more dietary fibre than non-diabetic men in The Netherlands and Italy, but not in Finland. The diet of diabetic and non-diabetic Finnish men differed little from each other and was characterized by high nutrient density of several vitamins and minerals. The proportion of protein of energy intake was higher among diabetic than non-diabetic Dutch and Italian men. CONCLUSIONS: The diet of the diabetic men from Finland, the Netherlands, and Italy resembled more the diet of non-diabetic men from the respective countries than the diet of diabetic men from the other countries. In the diet of Italian diabetic men, the proportions of fat, saturated fatty acids and carbohydrates were nearest the recommended levels. SPONSORSHIP: The National Institute on Aging, Bethesda, USA, the Dutch Prevention Foundation, the Hague, The Netherlands, the Academy of Finland, and the Sandoz Gerontological Foundation.

Familial sarcoidosis in Finland and Hokkaido, Japan--a comparative study.

Two or more cases of sarcoidosis in one family is not unusual. To compare the frequencies of familial sarcoidosis in Finland and Hokkaido, Japan, and to analyse the type of associations reported, we collected data on all patients visiting hospitals for sarcoidosis in 1984 in Finland (1378 patients) and Hokkaido (208 patients), including information about familial sarcoidosis. We also analysed the familial cases seen among 571 sarcoidosis patients diagnosed at the Mjölbolsta hospital in Finland from 1955 to 1987 and among 686 Japanese patients seen in Sapporo from 1964 to 1988. In 1984, 50 sarcoidosis patients visiting Finnish hospitals and nine sarcoidosis patients in Hokkaido reported as familial cases. Of the sarcoidosis patients seen in Finland at the Mjolbolsta hospital in 1955-1987, 27 had a family member with the same disease, while this number was 20 in the Sapporo hospital in 1964-1988. Those surveys give a prevalence of familial sarcoidosis in Finland of 3.6-4.7% and in Hokkaido of 2.9-4.3%. Among familial cases, the dominating relationships were sister-brother and mother-child relationships.

Allergic diseases, skin prick test responses, and IgE levels in North Karelia, Finland, and the Republic of Karelia, Russia.

BACKGROUND: There is growing evidence to show that atopic diseases are more common in Western Europe than in the former socialist countries of Eastern Europe. OBJECTIVE: The aim of this study was to assess whether a similar difference exists between the most eastern province of Finland and a neighboring western district of Russia. METHODS: A random sample of 25- to 54-year-old subjects was taken from the population registers in the North Karelia Province in eastern Finland and from the Pitkäranta district across the border in the western part of Russia. Participants filled out a questionnaire on atopic and allergic symptoms and participated in a clinical study, which included skin prick tests with 11 airborne allergens and IgE measurements. RESULTS: Self-reported hay fever, allergic eye symptoms, atopic eczema, and asthma were much more common in Finland than in Russia. In Finland 34.2% and in Russia 21.8% had at least one positive skin prick test reaction. In Finland 21.5% but in Russia only 15.8% had at least one elevated allergen-specific IgE value of the 5 values measured. From 6% to 47% of the differences in self-reported symptoms between the countries were explained by atopy, as measured by means of skin prick testing or specific IgE values. CONCLUSIONS: A major difference in clinical allergic diseases and signs of symptoms was observed between the 2 geographically adjacent areas. This suggests that the difference in clinical allergy and atopic disposition is related to the differences in lifestyle and environmental factors.

Associations between the use of antimicrobial agents for growth promotion and the occurrence of resistance among Enterococcus faecium from broilers and pigs in Denmark, Finland, and Norway.

This study compares the susceptibility of Enterococcus faecium isolated from pigs and poultry in Denmark, Finland, and Norway to antimicrobial agents used for growth promotion. E. faecium was isolated from 211 broilers and 55 pigs in Denmark in 1997, from Norwegian 55 poultry farms (turkey and broiler farms) and 4 swine farms between 1995 and 1997, and Finnish poultry (52) and swine (43) in 1996 and examined for susceptibility to avilamycin, avoparcin, bacitracin, flavomycin, monensin, salinomycin, spiramycin, tylosin, and virginiamycin. Only a limited number of isolates were categorized as resistant to monensin or salinomycin. In general, an association between the usage of antimicrobial agents in the respective countries and the occurrence of associated resistance was observed. Resistance to avilamycin was frequently observed among isolates from broilers in Denmark, where avilamycin has been used, whereas all isolates from Finland and Norway, where these drugs have not been used, were susceptible. The same phenomenon could be observed for avoparcin, bacitracin, tylosin, and virginiamycin; resistance was frequently observed among isolates from where these antimicrobials have been widely used, but rarely among isolates from where the use has been limited. Also for avoparcin and bacitracin, an association between usage and occurrence of resistance was observed. All isolates categorized as avoparcin resistant contained the vanX gene; isolates from broilers had the T variant in position 8,234 and isolates from pigs the G variant. Three (1%) of the 222 isolates resistant to tylosin contained the ermA gene and 196 (88%) ermB. Sixteen (11%) of the 146 virginiamycin-resistant isolates from broilers and two (7%) of the 27 virginiamycin-resistant isolates from pigs in Denmark contained the satA gene, whereas satA was not observed among any of the virginiamycin-resistant isolates from Finland. A total of 72% of the virginiamycin-resistant E. faecium from broilers in Denmark and all nine virginiamycin-resistant E. faecium from Finland contained satG. This gene was also observed among two (7%) of the virginiamycin-resistant isolates from pigs in Denmark. This study indicates that the use of antimicrobial agents for growth promotion in Denmark, Finland, and Norway have selected for resistance to most of these drugs among E. faecium in food animals.

Gender differences in the consumption of meat, fruit and vegetables are similar in Finland and the Baltic countries.

BACKGROUND: Women's diets are healthier than men's. Finnish women eat more fruits and vegetables but less meat than men. Gender differences may be larger in the Baltic countries, which represent Eastern European transition societies than in Finland, a society characterized by the Scandinavian welfare ideology and a high degree of gender equality. METHODS: The data are based on questionnaires to random samples of adults in Finland, Estonia, Latvia and Lithuania. The data provide a way of addressing gender differences at the turn of the century in the economically and culturally different countries. The purpose is to explore whether the consumption of foods classified as masculine or feminine-meat, fruits and vegetables-follow a similar gender pattern in Finland and the Baltic countries. RESULTS: Men ate meat more often while women ate fruits and vegetables. A high educational level was associated with frequent consumption of fruits and vegetables. Educational differences in the consumption of meat were few and inconsistent. The consumption of fruits and vegetables was more common in urban areas except in Finland. Gender differences were similar in all countries throughout age and educational groups and in rural and urban areas. CONCLUSION: The consistent association of gender and food and the similarity of gender patterning in population subgroups point to the stability of masculine versus feminine food habits. The similarity suggests that food habits contribute equally to the gender gap in health in the Baltic countries as they do in Finland.

The importance of policy orientation and environment on physical activity participation--a comparative analysis between Eastern Germany, Western Germany and Finland.

Environmental and policy interventions are seen as boosting physical activity because they are designed to influence large groups. However, they have not been much researched and the evidence on their role is still quite limited. The purpose of this study was to investigate differences in and relationships between policy orientation, the objective and perceived physical environment, and physical activity between Finland, Eastern Germany and Western Germany. The data are taken from a public telephone survey carried out as part of the international MAREPS project (Methodology for the Analysis of Rationality and Effectiveness of Prevention and Health Promotion Strategies; Eastern Germany, n = 913; Western Germany, n = 489; Finland, n = 400), statistics of sports facilities and policy documents. Results from the survey showed that Finns are more active than Germans and that they differ in their way of practising physical activity from Germans. Finns were more satisfied with their opportunities for physical activity and were better informed about physical programmes and measures. Finland also has the best opportunities in indoor sports facilities and outdoor sports grounds per number of inhabitants (excluding indoor swimming pools). Analysis of policy orientations showed that Finland had the most extensive 'Sport for All' policy, although West Germany's policy orientation did not differ that much from Finland's. East Germany's policy orientation was characterized by competitive sports. A policy orientation that places emphasis on the physical activity of the whole population seems to be related to better opportunities and a better infrastructure for sports and physical activity. This study suggests that there is a relationship between policy orientation, physical environment and physical activity participation.

Fifteen-year trends in coronary risk factors in Finland, with special reference to North Karelia.

The North Karelia Project, a major demonstration programme for coronary heart disease (CHD) prevention, was begun in an eastern province of Finland in 1972. A number of national CHD prevention activities have been undertaken, quite a few of them since 1977. This paper reports the 15-year changes in CHD risk factors (serum cholesterol, blood pressure, and smoking) in North Karelia and in the original reference area of the project, and more recent changes in a third area in southwestern Finland. The results are based on well-standardized, comparable surveys of cross-sectional populations, aged 30 to 59 years. The results indicate that risk factors reduced markedly in North Karelia from 1972-1977, to a lesser extent from 1977-1982, and only a little from 1982-1987. There was also a decline in the reference area during the first ten years (1972-1982) but the changes did not exceed those in North Karelia and during the second phase, from 1982-1987, risk factor changes were minor. Risk factor levels in the third area in southwestern Finland changed little from 1982-1987. Present serum cholesterol and blood pressure levels in North Karelia are still higher than in southwestern Finland, but smoking is less common among North Karelian men. These findings are discussed in the light of the recent information on Finnish dietary changes and CHD mortality; their bearing on the need for new cardiovascular disease prevention activities in Finland is also discussed.

Cardiovascular risk factor changes in Finland, 1972-1997.

BACKGROUND: The cardiovascular risk factor levels of the population have been assessed in Finland since 1972. In the beginning the surveys were done to evaluate the North Karelia Project, which was a community-based preventive programme. A national cardiovascular disease (CVD) prevention strategy was developed and implemented during the late 1970s. Subsequently, a national cardiovascular risk factors monitoring system was developed to assess the effectiveness of the national strategy. METHODS: Cross-sectional population samples were studied in 1972 and 1977 in North Karelia and Kuopio provinces in eastern Finland. An area in southwestern Finland was included in 1982, followed by the Helsinki metropolitan area in 1992 and Oulu province in northern Finland in 1997. A total of 19 761 men and 20 761 women aged 30-59 participated in the six surveys (1972, 1977, 1982, 1987, 1992, 1997). RESULTS: The serum cholesterol levels of both genders have continuously declined. Systolic blood pressure levels have declined since 1972, but no further decline in diastolic blood pressure was found in 1997. Smoking prevalence among men continued to decline mainly due to an increase in the percentage of never-smokers. For the first time the increase in smoking prevalence among women levelled off and started to decline, mainly because the number of female quitters had increased. CONCLUSIONS: These data suggest that the cardiovascular health programme in Finland has succeeded in decreasing the general risk factor level of the population.

Unintentional drowning in Finland 1970-2000: a population-based study.

BACKGROUND: While standard data on drowning reported by the World Health Organization (WHO) fails to provide a reliable picture of the burden of drowning in Finland, they suggest that the rates are much higher than those of other industrialized countries. AIM: To determine the true burden of drowning in Finland and factors related to its high rates. DESIGN: Descriptive, retrospective, population-based analysis of all deaths by drowning, among residents of all ages. SETTING: Finland, 1970-2000. MATERIAL AND METHODS: Mortality and population data furnished by Statistics Finland (SF) were used to determine age- and sex-specific drowning mortality rates using both nature- and cause-of-injury codes. Individual-level data from the death certificates were analysed and cross-linked to a nationwide postmortem toxicology database. RESULTS: From 1970 to 2000, 9279 unintentional drownings occurred (mean: 299.3/year SD 84.3, rate 6.1/100 000/year; M:F ratio = 8.6:1), accounting for 11.7% of all unintentional injury deaths. Drowning rates overall have decreased from 9.9/100 000/year in 1970-1972, to 4.5 in 1998-2000 (-2.7%/year; 95% CL: -3.0; -2.5). The most frequent activities related to drowning included boating (29.8%), falling (26.1%), swimming (25.0%), and activities on ice (12.4%). In non-boating-related drownings, 74.5% of males and 67.4% of females tested had a blood alcohol concentration (BAC) >/=50 mg/dl, while in boating-related drownings, the respective values were 78.1% and 71.4%. CONCLUSIONS: WHO statistics underestimate the true burden of drowning in Finland by up to 40-50%. Drowning rates and alcohol involvement in drowning are much higher than in other comparable developed countries. Broad-based countermeasures to reduce alcohol use in water activities are needed as part of any strategy to reduce drowning rates.

Acute myocardial infarction (AMI) in Finland--baseline data from the FINMONICA AMI register in 1983-1985.

The acute myocardial infarction (AMI) register of the FINMONICA study, the Finnish part of the WHO-coordinated multinational MONICA project, operates in the provinces of North Karelia and Kuopio in eastern Finland and in Turku, Loimaa and in communities around Loimaa in southwestern Finland. The AMI register serves as an instrument for the assessment of trends in mortality from coronary heart disease (CHD) and of the incidence and attack rates of AMI among 25-64-year-old residents of the study areas. This report describes the methods used in the FINMONICA AMI register and the findings during the first 3 years of the study, in 1983-1985. The criteria of the multinational WHO MONICA project were used in the classification of fatal events and in the diagnosis of non-fatal definite AMI, but based on the experience within the FINMONICA study, stricter diagnostic criteria than those originally described in the WHO MONICA protocol were used for non-fatal possible AMI. This led to a marked improvement in the comparability of the data from the three study areas with regard to the incidence and attack rates of non-fatal AMI. During the 3-year period the total number of registered events was 6266 among men and 2092 among women. Among men the incidence and attack rates of AMI and mortality from CHD were higher in eastern than in southwestern Finland. Also among women the incidence and attack rates of AMI were higher in eastern than in southwestern Finland, whereas there was no regional difference in mortality from CHD among women. The mortality findings of the FINMONICA AMI Register were in good agreement with the official CHD mortality statistics of Finland.

Fatal road accidents caused by sudden death of the driver in Finland and Vaud, Switzerland.

We investigated the incidence of fatal traffic accidents caused by sudden incapacity of the driver due to cardiac and other illnesses. The retrospective analysis was gleaned from Finnish traffic accident data files from 1984-1989, and police records of traffic accidents, from Canton de Vaud, Switzerland from 1986-1989. The annual rates of all traffic fatalities per million inhabitants were 125 in Finland and 212 in Vaud. Sudden driver incapacity due to acute illness caused 1.8 and 7.3 automobile driver deaths annually per million inhabitants in Finland and in Vaud, respectively. The corresponding rates for all-cause traffic deaths were 326 and 423, for driver deaths 105 and 167, and for those due to driver incapacity 4.7 and 15.6. Sudden driver incapacity caused 1.5% of all traffic deaths in Finland, and 3.4% in Vaud. Probable cardiac arrest caused 2.1% of all drivers' deaths in Finland and 1.7% in Vaud, respectively. Deaths caused by professional drivers' sudden incapacity were responsible for 0.11% of all traffic deaths in Finland, and for 0% in Vaud. Old age and short mileage were associated with illness-caused accidents. Accidents caused by sudden incapacity of the driver are rare causes of traffic deaths and hard to foresee. While this report relates to all drivers, we suggest there should be individual risk stratification for professional drivers with heart disease. However, non-professional drivers who are elderly and who have symptomatic cardiac disease should limit their driving to short distances and at low speed.

The prevalence of antibodies against Sindbis-related (Pogosta) virus in different parts of Finland.

OBJECTIVE: To study the occurrence of Sindbis-related (Pogosta) disease in Finland by serological means. METHODS: A total of 2250 serum samples from five different areas were included in the study. Four hundred samples were collected from healthy blood donors and 1850 samples from patients who were suspected to have some viral infection. Antibodies of IgG and IgM classes against Pogosta virus were measured. RESULTS: Eleven per cent of 2250 samples were positive for IgG and 0.6% were positive for IgM class antibodies against Pogosta virus. The antibody prevalence in Finland was almost equally distributed, being highest in western Finland (17%) and lowest in southern and northern Finland (9%). Of all samples with IgG class antibodies, 25% were taken from children under 10 yr of age. CONCLUSIONS: The prevalence of antibodies against Pogosta virus was much higher than we expected. Additionally, they were detected from all locations studied and not only in eastern Finland, which has been thought to be the main endemic area for this disease. Pogosta disease has been considered to affect mainly middle-aged persons, but our results indicate a high prevalence also among children.

Breast cancer trends: opportunistic screening in Austria versus controlled screening in Finland and Sweden.

The objective of the study was to compare the trends of incidence and of mortality of breast cancer in Austria, Finland and Sweden, where different mammography screening strategies (opportunistic versus controlled) are applied. Furthermore, to find out whether a change in screening strategies would be feasible for Austria. Age-standardized incidence rates (1983-2000) and mortality rates (1980-2001/2) were analysed. Furthermore, the annual per cent change and the annual rate change (annual rate change=+/-n/100,000 per year) and the 95% confidence interval were calculated. In all three countries, incidence rates increased significantly (Austria +26.4%, Finland +86.7%, Sweden +38.8%) during the period analysed (P<0.01). The annual per cent change and the annual rate change in Austria (1.57 and 1.56, respectively) are below the annual per cent change and the annual rate change in Finland (3.38 and 3.49, respectively) and in Sweden (1.80 and 2.19, respectively) for the period analysed. Total breast cancer mortality decreased significantly in Sweden since 1980 (-20.5%, P<0.01), in Finland since 1988 (-18.3%, P<0.05) and in Austria since 1990 (-19.8%, P<0.01). The annual per cent change and the annual rate change in Austria (-1.81 and -0.59, respectively) are below the annual per cent change and the annual rate change in Finland (-0.57 and -0.16, respectively) and in Sweden (-1.02 and -0.28, respectively) for the period analysed. In conclusion, despite its unsophisticated opportunistic screening, Austria does well in comparison with countries operating organized breast cancer screenings.

Atmospheric emissions, depositions, and transformations of arsenic in natural ecosystem in Finland.

For the last 2 decades, special attention has been paid to arsenic due to its high concentration in groundwater in many regions of the globe. There are not very many reports on arsenic concentration in the Finnish ecosystem, although the metal has been known to be highly toxic since ancient times. For the majority of people in Finland, the leading exposure route to arsenic is through food consumption. In this study, it has been observed that atmospheric emissions of arsenic from anthropogenic sources have decreased by 90%, which is due to better control technology and strict regulation. Aquatic discharge also was attenuated from 7.1 metric tons (t) in 1990 to 0.7 t in 1999. The concentration of arsenic aerosols in the atmosphere in Finland varies between 0.46 to 0.75 ng m(-3). Its use in pesticides and insecticides also has been phased out in Finland. There is no information available regarding arsenic species in the Finnish environment. Elevated concentrations of arsenic in groundwater has been reported for many countries. In Finland two hot spots are reported--one in the south of Finland and the second in Lapland. In these areas, arsenic concentration in well water is greater than 10 microg l(-1) (WHO recommended value: <10 microg l(-1)). It is believed that the release of arsenic into the Finnish groundwater is geogenic.

Prevalence of allergic rhinitis and atopic dermatitis among children in four regions of Finland.

The primary aim of the study was to evaluate the prevalences of allergic rhinitis and atopic dermatitis and their regional differences among Finnish children. The secondary objective was to determine whether the responses to the questions used are affected by the pollen season if asked during such a season. In 1994-5, the self-reported prevalence of allergic symptoms in four regions of Finland was studied among 11,607 schoolchildren aged 13-14 years, as part of the International Study of Asthma and Allergies in Childhood (ISAAC). The prevalence of rhinoconjunctivitis during the preceding year was 16% in eastern Finland (Kuopio County, n=2821), 23% in southern Finland (Helsinki area, n=2771), 15% in southwestern Finland (Turku and Pori County, n=2983), and 16% in northern Finland (Lapland, n=3032). The respective prevalences of flexural dermatitis were 15%, 19%, 16%, and 18%. The surveys were performed in winter, except in the Helsinki area where the survey was carried out mainly in the spring pollen season. Among the children studied in autumn in Helsinki, the prevalence of rhinoconjunctivitis was 19% and that of flexural dermatitis 17%. In multivariate analysis, flexural dermatitis was slightly more common in Lapland than in all other areas. In contrast, no significant differences were found in rhinoconjunctivitis. The prevalences of both disorders were twice as high in girls as in boys. In conclusion, regional differences in the prevalence of allergic rhinitis and atopic dermatitis were small in our country, and the prevalence figures were rather similar to those reported from other European countries. Almost half of the children had suffered from at least one atopic disorder, and over one-third had had symptoms in the past year. A clear season-of-response effect was observed; the prevalence of rhinoconjunctivitis was 25% when studied during the pollen seasons in the Helsinki area.

Decline in mortality from coronary heart disease in Finland from 1969 to 1979.

The trends in mortality from coronary heart disease in the 1970s and the differences in trends between counties within Finland were calculated from official mortality statistics among the population aged 35 to 64 years. During this period coronary mortality declined by a mean of 1.1% for men and 2.3% for women annually in the whole of Finland. A community based cardiovascular control programme was started in 1972 in North Karelia, a county in the east of Finland. The decline in coronary mortality in this county between 1969 and 1979 was 24% in men and 51% in women. The decline in the rest of Finland over the same period was 12% in men and 24% in women. The decline in North Karelia was greater than that in other counties of Finland for both men and women and that difference exceeded random variation, with over 95% likelihood for both sexes. Even with adjustment for rates before 1974 with cross-county multiple regression analyses the difference persisted. Although further studies are needed, the changes in coronary mortality in North Karelia suggest that the preventive programme has been effective.

Coronary risk factor levels: differences between educational groups in 1972-87 in eastern Finland.

STUDY OBJECTIVE: To compare differences in coronary heart disease (CHD) risk factor levels between educational groups in the 1970s and 1980s in eastern Finland. DESIGN AND PARTICIPANTS: Independent, cross sectional population surveys were undertaken in 1972, 1977, 1982, and 1987 of randomly selected men and women aged 30-59 living in two provinces in eastern Finland. Altogether 20,096 subjects participated. The lowest observed level of participation in either sex or province in any year was 77%. Serum cholesterol values and blood pressure measurements, body mass index, smoking, and the level of education were determined in each survey using comparable methodology. MAIN RESULTS: More poorly educated men and women had higher levels of all risk factors at the end of the study period (1987). There was no change between 1972 and 1987 in differences between educational groups in mean serum cholesterol values and the diastolic blood pressure level in either sex, and in smoking in men. In women, the proportion of smokers was highest in the better educated in the 1970s but lowest in this group in the 1980s (interaction between year of examination and educational level p < 0.01). Differences between educational groups in mean body mass index increased with time in both men (p < 0.001) and women (p = 0.06). CONCLUSIONS: Relative differences between socioeconomic groups in CHD mortality have increased in Finland in the 1970s and 1980s. Present results from eastern Finland show no reduction in differences between educational groups in risk factor levels, and even some evidence of increasing differences. Although a comparison between mortality trends and risk factor trends is problematic, trends in the risk factors analysed do not seem to be a major cause for the increasing differences in CHD mortality in Finland, at least in men. On the other hand, the risk factor trends analysed show no progress towards reducing inequalities in health, a major goal of public health policy.
