[The epidemiology of cerebral stroke in Siberia based on registry data]

In accordance with WHO MONICA Project during 1987-1988 the epidemiological investigation of cerebral stroke was performed using register method in west Siberia (Novosibirsk), in east Siberia (Krasnoyarsk) and in Far East (Tynda, Anadyr). 945 new cases of cerebral stroke in the investigated population (473720 men) were evaluated. Standard by age the stroke mobility and mortality was equal to 2.0 and 0.5 cases in 1000 Novosibirsk's inhabitants, 2.4 and 0.9 in Krasnoyarsk, 2.9 and 1.0 in Tynda, 2.9 and 1.6 in Anadyr respectively. Data about factors of stroke risk, seasonal and circadian rhythms of mobility, age-sex structure of patients were obtained. The authors came to the conclusion that the frequency of stroke and especially haemorrhage, of the brain mobility and mortality had tendency to increase in the direction from west to east of Siberia though its regional differences was relatively small.
