RESUMEN
The study reveals main methodological approaches in monitoring and evaluating role of socially significant infectious diseases in reducing quality of public health in the Russian Federation. The article proposes at population level the grouping of main risk factors affecting quality of public health, exemplified by epidemiology of tuberculosis. The purpose of the study is to develop methodology of exploration of impact of socially significant infections on decreasing of quality of public health exemplified by epidemiology of tuberculosis as infectious disease that is well studied in medical social aspects and having fully functioning TB control and high level monitoring system. The informational analytical methodology was applied conjointly with critical analysis of national and foreign publications, normative legal acts, selected through scientific search systems PubMed, Medline, www.base-search.net, www.refseek.com, E-library, CiberLeninka, "Garant" and "ConsultantPlus". The depth of search was limited by 15 years and more. The data from the federal statistical observation form No. 8 "Information about diseases with active tuberculosis" for 2021 was also evaluated. For the first time, the grouping of main risk factors of socially significant infections , affecting decrease of quality of public health at population level are proposed. The mentioned factors are grouped as epidemiological; social economic (including economic damage caused directly by tuberculosis); demographic; behavioral; biomedical (presence of diseases not associated with tuberculosis, but reducing immunity); climatic geographical, etc. The further analysis and listing of specific indicators of each group of factors is required in order to monitor and quickly assess impact of socially significant infectious diseases on public health in the Russian Federation and its Subjects. The analysis of scientific literature demonstrated that, despite breadth of studying tuberculosis risk factors, they are non-systematized and fragmented. The methodological approaches to studying impact of socially significant infectious diseases on public health in foreign countries and in the Russian Federation, are practically absent. The compilation and actualization of listing of indicative indicators for each group of factors with the choice of statistical methods of their calculation, evaluation and interpretation will permit to develop methodological approaches to monitoring and assessing role of tuberculosis (hereinafter - HIV infection, parenteral viral hepatitis, etc.) in altering quality of public health in the Russian Federation with development of rapidly updated database of selected indicators at the level of each Subject of the Russian Federation.
