Динамика смертности и ожидаемой продолжительности жизни населения арктического/приарктического региона России в 1999-2014 годах
This article presents the results of analysis of mortality dynamics among population of 9 territories of Arctic and Subarctic regions, using linear regression technique. Allcause mortality reduction was significantly greater in the 4 territories of the country. These 4 regions were: Murmansk region and Komi Republic (for females), Archangelsk region (for both sexes) and Republic Sakha (Yakutia) (for males). The following regions displayed mortality reduction which was close to national averages or less: YaNAO, KhMAO and Magadan region. Mortality rates among males declined faster than that among females. Relatively lower mortality indicators in the territories of YaNAO and KhMAO could likely be attributed to migration of the population to midlatitude regions with accumulated burden of northern pathology. Mortality reduction tendencies from the leading death causes (diseases of circulatory system, respiratory diseases, external causes) in the region are close to national averages. The most strongly mortality reduced from brain strokes, myocardial infarction and external causes of death. The mortality rates and the mortality dynamics can be described as relatively positive in the region on the whole, except for “other diseases of circulatory system” category, where mortality rates exceeded national average twice in particular years. Life expectancy in the Arctic region is close to that in Russia, except two autonomous regions KhantyMansiisky and YamaloNenetsky, where life expectancy was higher than national average by 1.7 and 2.6 years among males and by 0.4 and 0.7 years among females, respectively. The situation in Nenetsky and Chukotsky Autonomous Regions and in Magadan region remains unclear because of possible inaccuracy of primary data.
