Effect of seniority duration on miners health in the Kola Arctic region
Study was to examine the health status of 2 832 miners of the Kola Arctic at various stages of their labor activity. It has been established that even with the of 2 years, there is an increase in the number of health disorders in one worker, a decrease in the number of healthy individuals, an increased risk of developing diseases of the musculoskeletal system (RR 1.74, CI 1,10-2,75). With increasing length of service for every five years there is a progressive deterioration in the health of miners. Major changes in the state of health of miners occur in the first 15 years of work. In subsequent years, there is a stabilization of the indicators with minimal differences between the experience groups of 16-20 years, 21-25 years and more than 25 years. The conclusion was made about the need to conduct targeted health building activities, especially the prevention of musculoskeletal diseases, at the earliest stage of miners' professional career.
