Dynamics of deaths and mortality rate in Kazakhstan population

Objective: To evaluate the Kazakhstan population`s mortality dynamics on the number of deaths and rates from 2018 to 2020, according to region of residence, and gender. Methods: Overall, retrospective analysis of 389 674 deaths of Kazakhstan residents from 2018 to 2020 was conducted using the ICD-10 version. The sources of information were official data on the size and deaths from the RPN database "Register of Death Certificates," the Statistics Agency of the Republic of Kazakhstan. We used a one-factor linear regression analysis of the main trends of deaths and mortality rate by place, gender, and country level. The results of the regression analysis were presented in the form of non-standardized coefficients (b) and the level of statistical significance (p). Results: There was a statistically significant increase in the total mortality rate of Kazakhstan's population (regression statistics b=17938.0. p=0.302) and by gender during the period under study in 2018-2020. Among the male population, the mortality rate increased by 1.4 times (regression statistic b=9827.5. p=0.292) and the female population – 1.3 times (regression statistics b=8110.5, p=0.313) in the same years. The leading causes of death for the population of Kazakhstan and by gender were non-communicable diseases (the circulatory system ("I"), diseases of the nervous system ("G"), respiratory diseases ("J"), malignant neoplasms ("C") and digestive diseases ("K") during the period from 2018-2020. While for women, nervous system diseases ranked first, and unclassifiable diseases ranked fifth. Conclusion: Thus, the increase in Kazakhstan's population mortality rate was determined in general and by disease classes during the studied time from 2018 to 2020. The leading causes of death for Kazakhstan's general population and by gender were non-communicable diseases despite of effects of COVID-19. Kazakhstan's Northern and Eastern regions had the highest mortality rates in the country and by sex
