Altogether 6,523 persons aged 25-64 years were studied in eastern and south-western Finland to determine their cardiovascular risk factor levels. Among men, smoking was more prevalent in the south-western area (41 vs. 37%), serum cholesterol levels were higher in the eastern area (6.2 vs. 6.0 mmol/l) and blood pressure levels were the same in both areas (145/86 in the east vs. 144/86 in the south-west). Among women, smoking was also more common in the south-western area (24 vs. 16%) and serum cholesterol levels were higher in the eastern area (6.1 vs. 6.0 mmol/l) as well as blood pressure levels (142/84 vs. 138/81 mmHg). Among both genders, prevalence of hypertension and proportion of persons on antihypertensive drug therapy was higher in eastern Finland. The comparison of these findings with the results from previous studies carried out among men in these two areas indicates that the risk factor levels have been decreasing in both areas and that the previously observed differences in risk factor levels between eastern and south-western Finland (the levels used to be higher in the east) have levelled off. The favourable development in eastern Finland may be a result of the North Karelia Project.
