Cardiovascular diseases and diabetes mellitus in different ethnic groups: the Finnmark study.
The mortality from coronary and cerebrovascular diseases is higher in Finnmark County than in other Norwegian counties. In a population-based cohort study, we compared the incidence of myocardial infarction, stroke, and diabetes mellitus in different ethnic groups in Finnmark. A total of 10,622 subjects of Norse, Sami, and Finnish origin were followed for 14 years. During approximately 150,000 person-years, we identified 509 and 84 cases of myocardial infarction, 107 and 75 cases of stroke, and 96 and 73 cases of clinical diabetes mellitus among men and women, respectively. A total of 533 men and 199 women died. Norse subjects born outside of Finnmark had the most favorable risk factor levels and, in general, the lowest incidence of disease. Men of Finnish origin had a higher incidence rate of all endpoints than other men, and Finnish women had a higher incidence rate of myocardial infarction than other women. Sami women were more obese but did not have a higher diabetes mellitus incidence than other women. After adjustment for major cardiovascular risk factors and height, most ethnic differences were attenuated.
