# Impact of Environmental Conditions on the Health of the Far Eastern Region Population
## 3 Results  
The main demographic indicators of the population of the Far Eastern region from 2014 to 2017 are presented in the Table 1.  
The data in Table 1 show that the population in 2017 compared to 2014 decreased by 53.5 thousand people. The reason for this was migration outflow; however, the problem of natural population decline still persists. The number of births in the Far Eastern Federal district recently increased slightly; however, this was not enough to increase the population overall. If mortality is to be considered, an analysis of the situation requires overall mortality rates, which are calculated as the ratio of the total number of deaths per year to the average annual population. The Far East takes third place in mortality among other areas of the Russian Federation. The highest value of the total mortality rate belonged to the Jewish Autonomous region and the Amur region. The number of deaths due to respiratory diseases increased by 4.06%, and those due to neoplasms increased by 16.01% compared to 2014. Total indicators of socially significant diseases (diabetes mellitus, hypertension, malignant neoplasms) and mortality in the Far Eastern Federal district for 2014-2017 are presented in Figure 1[13]. Figure 1 shows that there was a steady direct relationship between the mortality and socially significant diseases in the population. The smaller the number of registered diseases, the lower the mortality. As a result of the study, the dependence of the main causes of mortality (neoplasm, organs of the circulatory system, respiratory organs, and digestive organs) on the total amount of harmful emissions in the Far Eastern Federal district revealed that environmental pollution had a negative effect on public health. \begin{table}

Table 1: Main demographic indicators of the population of the Far Eastern region in 2014–2017. This hypothesis is supported by the regression equations presented below in Table 2.  
\(\text{M}_{\text{oncology}}=-2.26x_{1}+2.27x_{2}-3.02x_{3}-1.58x_{4}\)  
\(\text{M}_{\text{strokes}}=-2.71x_{1}+11.12x_{2}-11.66x_{3}-7.57x_{4}\)  
\(\text{M}_{\text{diseases of the respiratory system}}=-1.66x_{1}+2.02x_{2}-2.49x_{3}-1.23x_{4}\)  
\(\text{M}_{\text{diseases of the respiratory system}}=0.0025x_{1}+2.42x_{2}-2.67x_{3}-1.86x_{4}\)  
where x\({}_{1}\)--the number of emitted hydrocarbons in the atmospheric air (thousand tons);  
x\({}_{2}\)--total emissions (thousand tons);  
x\({}_{3}\)--the number of emitted sulfur dioxide in the atmospheric air (thousand tons);  
x\({}_{4}\)--amount of discharged polluted wastewater (thousand m\({}^{3}\)). The urbanization of the population was 75.43% in 2017. Urbanization contributes to an increase in the concentration of anthropogenic load, resulting in a more polluted environment. This, in turn, negatively affects both the physical and mental state of the population. Sometimes the urban environment cannot keep up with the rapid growth, therefore the quality of water and air in many cities in the Far Eastern Federal district do not meet the standards. Therefore, the unsatisfactory state of air and water resources can lead to an increase in the incidence rate. In 2017, compared to 2015, the number of patients diagnosed for the first time with neoplasm disease increased by 16.8%, with endocrine diseases by 5.4%, and with respiratory diseases by 16.1%. The highest number of cancer diseases in 2017 was recorded in the Chukotka Autonomous district (15.7 cases per 1000 people) and the Sakhalin region (14.5 cases per 1000 people). The lowest rate was established in the Magadan region (6.4 cases per 1000 people).
