Age-sex model of mortality from cerebrovascular diseases among the Irkutsk Region population

Introduction. Cerebrovascular diseases are a medical and social problem for developed countries in the second half of the 20th century and the beginning of the 21^st century. The study of special mortality rates makes it possible to study in depth the nature of this pathology, its intensity among the population and to formulate reasoned program solutions aimed at reducing its frequency in the population.
The aim of the research is to identify trends and features of the dynamics of mortality in connection with cerebrovascular diseases in different age and sex groups of Irkutsk Region population.
Materials and methods. The subject of the research is deaths from cerebrovascular diseases among Irkutsk Region population for the period of 2000–2020. A continuous method of statistical observation was used; the grouping of the material was carried out by distributing the deceased by sex and five-year age interval, with subsequent calculation of mortality tables. The dynamics of the quantitative measure of mortality was determined by calculating the matrix of time series indicators.
Results and discussion. For the period of 2000–2020, in the Irkutsk Region, there was a decrease in mortality rates from cerebrovascular diseases both among the male and female population. Mortality rates by sex are higher among the male population, as indicated by the ratio of the ratio of mortality between men and women in all age intervals. The multiplicity of the ratio of indicators increases during the research period from the maximum values of 2.1 times in 2000 to 5.0 times in 2020. The maximum difference shifts from the age of 55–59 to the age group of 40–44. The intensity of mortality reduction in the dynamics of 2000–2020 among the female population is higher than the male. Based on the results of the analysis of the time series, it was found that the age-specific exponent of mortality in the content of 1 % of the mortality increase has a more pronounced quantitative measure for the male population.
Conclusion. As the result of the research, for twenty-year observation period a decrease in mortality rates from cerebrovascular diseases was revealed. The age-specific mortality rate from cerebrovascular diseases in the male population is higher than in the female population. The maximum intensity of the difference in mortality between men and women is reached in the working age groups. The content of the indicator 1% of increase in deaths in the male population is higher than that of the female. State policy in the development and implementation of target-oriented programs for reduction of mortality should be based on thorough analysis of data of administrative districts.
