EVALUATION OF AGE AND SENIORITY DYNAMICS OF THE RISK OF HEALTH DISTURBANCES IN MINERS OF THE ARCTIC ZONE OF RUSSIA

Abstract

Introduction. Despite the improvement of technologies used in mining enterprises, most miners of the Arctic zone of Russia has harmful working conditions. However, miners’ health status is affected not only by harmful production factors, but also by severe climatic conditions of the Arctic, harmful behavioral factors (e.g. smoking), and the processes of natural aging of the organism. The aim of the study was to differentiate and hygienically assess the professional and non-professional fractions of the annual increase in risk (AIR) of chronic health disorders of miners and their comparison with officially approved hazard classes of working conditions. Material and methods. The results of a targeted periodic medical examination of 700 miners of the underground apatite-nepheline and copper-nickel mines were analyzed. 301 cases out of them, according to the developed method, were included in the studies. Two age groups and four seniority groups of workers have been formed. Results. The results of the study showed the possibility of using the criterion of AIR of chronic diseases for assessing the degree of harmfulness of working conditions based on health indices for miners in the Arctic zone of Russia, Miners have professional AIR of diseases of the musculoskeletal system, digestive organs, respiratory organs and nervous system exceeding the control levels by 2.3, 7.0, 5.0 7.0 times, respectively. Conclusion. The values of professional and non- professional factors for the risk of diseases of the musculoskeletal system and respiratory organs were drawn to almost coincide, which indicates a pronounced adverse effect of environmental factors on the health of miners in the Arctic zone of the Russian Federation.
