[Meteorological risk factors of stroke].

Based on correlation analysis of stroke, recorded in Khanty-Mansiysk during 5 years, and standard meteorological factors, we found the significant relationship between the frequency of stroke and daily temperature amplitude. The positive correlation between the frequency of stroke and between-day changes in air temperature in the combination with changes in atmospheric pressure during 3 h was identified. A maximal number of strokes was recorded in December, April, May and July and a minimal number was in January, June, August and September.

[Clinical and epidemiological characteristics of stroke in the Khanty-Mansi autonomous region].

A study of registry data revealed that morbidity, mortality, early lethality and frequency of secondary cases of stroke were significantly lower compared to those in the Russian Federation that could be explained by the younger mean age of the population in the Khanty-Mansi autonomous okrug (KMAO). Annual frequency of new cases of stroke among men was higher than among women though the prevalence of risk factors was lower in men. The levels of morbidity in men and women differed significantly than in the country as a whole.
