Morbidity of the working-age population depending on the Russian regions’ characteristics in 2011—2022 yrs

Investigation of the formation patterns of morbidity levels of the working-age population in Russia depending on the external factors (environmental, socio-economic, ecological and other living conditions) was not carried out. Objective. To perform an analysis of the influence of regional living conditions as well as medical and organizational characteristics of regions on morbidity of the Russian population of working age. Materials and methods. Calculation of indicators of primary and overall morbidity of the working-age adult population was carried out on the basis of data of the Russian Research Institute of Health. Medical and organizational characteristics of the regions of Russia were obtained on the official website of the Federal State Statistics Service. To assess the living conditions of the Russian population, 4 regional indices developed earlier in the National Medical Research Center for Therapy and Preventive Medicine (NMRC TPM) were used: economic, demographic, industrial, social. All indicators were considered for 2011—2022. Linear regression analysis was used to estimate the associations of morbidity with regional indices and medical and organizational characteristics for each year of the observation period. Results. Primary and overall morbidity is higher in regions with developed industry and high capacity of outpatient facilities in the studied period starting from 2014—2016. In addition, the overall morbidity is declining in the regions with high population per staff nurse. A tendency of association of morbidity with the Demographic Index appeared in 2020—2022: the more the population structure of the region is shifted towards younger age groups, the lower the morbidity. Conclusion. The performed analysis showed stable associations of regional living conditions and medical and organizational characteristics of the regions with morbidity of the Russian population of working age. During the COVID-19 period, the demographic structure of the population became an additional regional factor in the formation of morbidity levels.
