Analysis of the Structure of Occupational Pathology in the Republic of Bashkortostan

Abstract

Significance. Occupational morbidity is an important component among other indicators used in assessing health of employees. Studying dynamics in this indicator over several years makes it possible to identify specifics of prevalence of occupational diseases within certain territories. Purpose. To identify dynamics in the structure of occupational morbidity in the Republic of Bashkortostan during 2000-2019 on the basis of the medical and statistical analysis. Material and methods. The authors have analyzed 2,561 cases in the Register of occupational diseases to develop their medical and statistical profile. Results. The study found out that the Register of individuals with occupational diseases included 61.8% of males, 60.4% of urban residents with people aged 50-59 and 40-49 prevailing (52.4% and 33.4%, respectively). 3.8% of people in the Register had a 5-year exposure to occupational hazards, 10.6% - a 5 to 10-year exposure to occupational hazards, 15.3% - a 10 to 14-year exposure and about 20% of people had more years of exposure to occupational hazards. In dynamics, there was an increase in the share of males and people aged 50-59 with more than a 25-year exposure to occupational hazards. Determining causes of occupational diseases made it possible to identify that diseases of the musculoskeletal system and connective tissue accounted for one third of the occupational disease causes, diseases of the respiratory system accounted for one-fifth, injury, poisoning and consequences of other external exposure accounted for one sixth, while diseases of the nervous system and other diseases accounted for one tenth of all causes of occupational diseases. In dynamics, there was an increase in the share of diseases of the musculoskeletal system and decrease in the share of respiratory diseases. In the structure of diseases, radiculopathy prevailed (20.2%) followed by vibration disease (13.2%). Vibroacoustic factor (28.9%), chemical factor (24.1%), severity and intensity of the labor process (22.9%) are the leading factors in the structure of the working environment and labor process. In 2014-2019, there was an increase in the share of factors of the labor process (severity and intensity).
