Population’s mortality due to diseases of the circulatory system in the Irkutsk region at the beginning of the XXI century: age-gender aspect

Introduction. Special indicators of mortality from diseases of the circulatory system allow studying in depth the nature, intensity and formulating reasoned program decisions aimed at reducing this pathology.

The purpose of the study. Assess the mortality of the population by gender and age from diseases of the circulatory system in the Irkutsk region over the period of 2000–2020.

Materials and methods. The subject of the study was mortality according to the class of circulatory system disease. Continuous observation was used using the statistical accounting form C51. The calculation of gender and age mortality tables and the elimination of differences in the age composition of the population was carried out by the direct method of standardization. Age-gender mortality was studied using complex time series analysis.

Results. Calculations of ordinary and standardized mortality rates showed the mortality rate of the male population to be higher in almost all age groups. The mortality rate reaches a 4.5-fold excess in the 30–34 age group among men in 2000. Calculation of the expected number of deaths in the standard over the twenty-year study period revealed a higher gap in mortality rates from circulatory diseases in the male population and its shift to older age groups. The multiplicity of the expected number of deaths in the standard was a higher gap in the indicators in the male population for the age of 15–19 years — 6 times, 55–59 years — 5.7 times. The trend in age-related mortality — in the content of a 1% increase in mortality in cases, showed a pronounced character among the male population.

Research limitations. When studying the usual and standardized mortality rates from diseases of the circulatory system for the male and female population in the Irkutsk region, statistical analysis of data for the period 2000–2020 was used.

Conclusion. An age-gender assessment of mortality from diseases of the circulatory system revealed: a predominance of the mortality rate of the male population over the female population and an increase in this gap in older age groups; an increase in the mortality rate in older age groups; the significance of standardized mortality rates.
