Male mortality from ischaemic heart disease in Finland: relation to region of birth and region of residence.

"The purpose of the study is to shed light on the causes of the large difference in mortality from ischaemic heart disease (IHD) between East and West Finland. The study is based on the death certificate records on deaths from IHD in 1971-1975 among Finnish men aged 35-64. These records were linked with the records on persons in the 1970 census. Mortality from IHD is analyzed simultaneously by region of birth and region of residence, controlling for several socio-economic and demographic variables, by means of log-linear models. The analysis shows that being born in East Finland and living there both increase the risk of IHD, but that being born in East Finland is a more important risk factor than is living there."
