External Causes in the Structure of Premature Mortality in the Republic of Sakha (Yakutia)

The purpose of this survey was to study the rate, trends and patterns of mortality from external causes in the Republic of Sakha (Yakutia) [RS(Y)]. A retrospective analysis of statistical data on mortality rate (MR) of the population in Yakutia in the period between 1990 and 2017 was carried out.
The results obtained suggest that the population mortality pattern in Yakutia consists of a high proportion of losses from external causes in young age groups. Suicides dominate the structure of external causes of death in Yakutia (20.7% in 2017), followed by homicides (13.6%), cold temperature exposures (11.4%) and road traffic accidents (8.7%). The annual loss of the working-age population in RS(Y) makes up over 40% in the total number of deaths. In the structure of the causes of mortality of the working-age population during the entire study period, accidents, poisonings and injuries ranked first, followed by circulatory system diseases and neoplasms. Thus, the main trends that have a negative impact on the creation of the workforce system in RS(Y) are as follows: the high MR of the working-age population of both sexes; the overmortality of working-age men; the prevalence of preventable causes of death of an exogenous nature (accidents, poisonings, injuries); and an increased share of retirement-age people, resulting in an increased demographic load on the able-bodied population.
