Description of the Incidence among Population of Industrial Cities in the Irkutsk Region

The industrial cities of Irkutsk region are a type of socio-ecological systems, the population of which for a long time lives under the combined influence of adverse technogenic and socio-economic factors. The aim of the study was to assess the characteristics of the general incidence of the population of industrial cities in the Irkutsk region (Angarsk, Shelekhov) in the first and second decades of the XXI century. Methods. The morbidity indicators for the appeal of the population for medical care presented by healthcare institu- tions in statistical form N 12 were analyzed. We evaluated the characteristics of diseases detected for the first time inlife (primary incidence). To identify trends in the dynamics of morbidity indicators, the method of regression analysis (linear and quadratic functions with a free term) was used. Results. In the dynamics of the general indicator of the primary incidence in both studied cities, no tendencies for steady growth or decrease were revealed. At the same time, in the dynamics of indicators for some classes of diseases, there were statistically significant trends in the increase in incidence (classes of diseases of the musculoskeletal system, diseases of the genitourinary system, respiratory diseases), as well as trends in the decrease in incidence (classes of infectious diseases, neoplasms and skin diseases). Conclusion. The changes in the structure of primary morbidity that have occurred over 14 years indicate pathomor- phism of the pathology, for which the population is seeking medical help. An increase in the prevalence of diseases of the musculoskeletal system, diseases of the genitourinary organs and others among the population can be caused by both the aging processes of the population and changes in lifestyle (especially young people) that occur under the influence of negative factors of the sociocultural environment and others.
