title: [Epidemiology of stroke in Siberia].
abstract: Based on WHO MONICA methods and diagnostic criteria, it is shown that first-ever stroke incidence and mortality in Siberia (a total number of residents included in the analysis varied from 450,000 to about 800,000) that are among the highest in the world. In Novosibirsk, for the period from 1982 through 1991 there was a trend towards decreasing stroke incidence and mortality rates, but for the period from 1992 through 1997 there was a trend towards increasing there rates in both men and women. Age-standardized (US white population was used as a standard) stroke incidence rates increased from west to east and from south to north across Siberia, with a corresponding increase in the proportion of hemorrhagic strokes. In 1987-1988, age-adjusted stroke incidence rate in Novosibirsk was 212 per 100,000 residents per year, in Krasnoyarsk--325, in Tynda--329, in Anadyr--348. Stroke-case fatality rates ranged from 28% in Tynda to 41% in Anadyr. A multivariate regression analysis revealed that hypertension, left ventricular hypertrophy, ischemic heart disease. mitral valve disease, current cigarette smoking, excessing body mass index, winter season, and low ambient temperature are all significant and independent risk factors for the occurrence of ischemic stroke in Novosibirsk. A significant association between stroke occurrence and air pressure/geomagnetic activity change was found. Possible reasons for such unfavorable trends in stroke incidence in Siberia are discussed, and an optimal approach for improving organization of cerebrovascular disease care is suggested.
