DYNAMICS IN CRUDE INCIDENCE OF DISEASES OF THE MUSCULOSKELETAL SYSTEM AND CONNECTIVE TISSUE IN THE ADULT POPULATION OF THE REPUBLIC OF BASHKORTOSTAN IN 2015–2019

Significance. Rheumatic diseases belong to the group of the most socially significant diseases and have a negative impact not only on the patient and his family, but also on the State as a whole. According to the 10th Revision of the International Classification of Diseases, rheumatic diseases are mainly classified in Chapter XIII - "Diseases of the musculoskeletal system and connective tissue". Epidemiological studies are needed to assess the scale of the problem. The purpose of the study was to evaluate dynamics in crude incidence of diseases of the musculoskeletal system and connective tissue (in general and by individual nosological forms/groups) in the adult population of the Republic of Bashkortostan (Russian Federation) in 2015–2019. Material and Methods. A retrospective observational study was carried out. The object of the study included residents of the Republic of Bashkortostan aged over 18, and the subject was crude incidence of diseases of the musculoskeletal system and connective tissue (in general and by individual nosological forms/groups: osteoarthritis, rheumatoid arthritis, reactive arthropathies, dorsopathies (including spondylopathies and separately ankylosing spondylitis), osteopathies (including osteoporosis), systemic connective tissue disorders) in the adult population of the Republic of Bashkortostan in 2015–2019. Data on crude incidence were obtained from the statistical data of the Medical Information and Analytical Center of the Ministry of Health of the Republic of Bashkortostan, as well as annual statistical materials of the Ministry of Health of the Russian Federation. Results. The crude incidence of diseases of the musculoskeletal system and connective tissue (in general) in the adult population of the Republic of Bashkortostan increased over the study period 2015-2019. Analysis by individual nosological forms/groups shows that crude incidence of osteoarthritis, rheumatoid arthritis, reactive arthropathies, dorsopathies, including spondylopathies (including ankylosing spondylitis) in the Republic of Bashkortostan has also increased by 2019, while crude incidence of systemic connective tissue disorders and osteopathies, including osteoporosis has decreased. Furthermore, a number of differences have been revealed in the dynamics in the indicators under study in the Republic of Bashkortostan and in the Russian Federation as a whole for the period 2015–2019. Conclusion. The data obtained indicate the presence of pronounced regional and nosological features in the dynamics in crude incidence of diseases of the musculoskeletal system and connective tissue in the adult population of the Republic of Bashkortostan in 2015–2019.
