Abstract
Background: Modern methods of epidemiological analysis allows us to assess the levels, structure and dynamics of morbidity, and its relationship with environmental factors in the region. We aimed to study the degree of influence of environmental factors on respiratory diseases morbidity in the Russian Far East.
Methods: The data of clinical and epidemiological monitoring of respiratory diseases in the Far Eastern region of Russia for the period 2010-2017 were assessed. The methods of comparative, cluster and correlation analysis, and of predictive modeling were used.
Results: Among the indicators that determine the degree of access to healthcare there was determined the population density (r=-0.3801), the poverty level (the proportion of the population with incomes below the subsistence minimum) (r=-0.3680) and the value of the gross regional product (r=0.5345). Correlation analysis revealed the degree of dependence of the primary incidence of various nosological forms of respiratory diseases on climatic factors. The ambient temperature has the most powerful influence on the pneumonia (r=-0.8183) and asthma (r=-0.7270) morbidity, and atmospheric air humidity on the asthma (r=0.7136) and chronic bronchitis morbidity (r=0.5576). On the basis of the regression analysis the predictive model of respiratory diseases prevalence in the climatic and socio-economic conditions of the Far East region is formed, the linear trends of which are progressive.
Conclusion: Epidemiological features of respiratory diseases prevalence in the Far East region of Russia are determined by differences in climatic and socio-economic conditions.
