# Impact of Environmental Conditions on the Health of the Far Eastern Region Population
## 1 Introduction  
The Far Eastern region is the largest of the Russian Federation districts with an area of 6,169,329 km\({}^{2}\) that includes nine sub-regions. In 2017, the population of the Far Eastern region was 6,165,284 and the population density was 1.2 people/km\({}^{2}\).  
Currently under the influence of harmful substances that have average annual levels exceeding health standards, there is the entire population of the Far Eastern region, whose main representatives are Russians, Ukrainians, Yakuts, Koreans, and small populations of indigenous peoples (Evenks, Nanai, Udege, etc.). The Far Eastern region is characterized by a diversified industrial production, resulting in the presence of a large number of sources of environmental pollution that cause serious hygienic and medico-demographic problems within a territory [1; 2].  
International scientific results from research in this area show a close relationship between the state of the environment and diseases of various etiologies [3; 4; 5; 6].  
The macrostructure of the industrial and economic potential of this area of the Russian Federation is determined by leading industries such as mining, the construction of the Vostochny cosmodrome and the Power of Siberia gas pipeline, and the production and distribution of electricity. These industriesform a whole complex of sanitary and hygiene problems which cause direct and indirect effects on the population, including the appearance of cancer. The assessment of the habitat of the Far Eastern region indicates that the amount of pollutants emitted from stationary sources annually into the atmospheric air increased over the period of 2014-2017. In 2014, emissions from stationary sources amounted to 987.96 thousand tons, while in 2017 the volume of emissions amounted to 1102.12 thousand tons. The majority of the total volume of emissions in 2017 was made by the Republic of Sakha (Yakutia) and Primorsky Krai with 50.04 and 64.12 thousand tons, respectively.  
Currently, health problems in the population have worsened due to the unfavorable environmental situation. Across the region there is a tendency towards a decrease in the level of public health. It has been proven that the state of health is negatively affected by air, water, and soil pollution. Drinking water supplies and food products containing xenobiotics of various origins are environmentally unsafe. Negative environmental stressors adversely affect the birth rate and the health status of newborns. As the natural population decline increases, the working-age population decreases [7; 8; 9; 10; 11; 12].  
The purpose of this study was to assess the medical and environmental situation in the Far Eastern region and to identify causal relationships between environmental factors and the incidence of diabetes mellitus, hypertension, malignant neoplasms in the population.  
To achieve this goal, the following tasks were conducted:  
1. Assess the medical and demographic situation in the Far Eastern region.  
2. Conduct a correlation-regression analysis of the impact of some environmental factors on socially significant diseases (diabetes, hypertension, malignant neoplasms) and mortality in the Far Eastern Federal district.
