[Main indicators of morbidity and expected long life of the population of the northern region of Russia].

This article analyzes the main indicators of the incidence and life expectancy of the population of the Republic of Sakha (Yakutia) over a twenty-year period. An increase in the incidence rate of the population was revealed that exceeded the average for the country and the Far Eastern Federal District, including for oncological diseases, the level of which increased several times in the republic. The value of the indicator of life expectancy in the republic approached the average Russian level, while 20 years ago a much lower indicator was determined. In the dynamics of indicators of the morbidity of the population and life expectancy over a twenty-year period, a polynomial trend has been outlined. For example, the incidence of neoplasms and diseases of the circulatory system showed a sharp increase in 2004, followed by a decrease, for diseases of the digestive system - similarly, an increase in 2001 and a subsequent decrease. This aspect requires an additional detailed study of the causes of such changes in order to be able to predict them in the future.
