The article is devoted to consideration of the spatial-temporal structure of the primary morbidity and prevalence of the respiratory organs diseases among the population of the Sumy region. The article based on the data of annual statistical reports of medical institutions of Sumy region, which are subordinate to the Ministry of Public Health of Ukraine. The article used the methods of factor and correlation analysis, as well as methods of mathematical-statistical analysis, and ranking. The authors analyzed the spatial-temporal structure of respiratory organs pathology among the population and revealed the territorial differences and the dynamics of respiratory morbidity of the population. Nosogeographic assessment of territory of the Sumy region, which was carried out according to the integral respiratory diseases morbidity index (IMI), shows that today the highest values of IMI are obtained by analyzing the incidence rate in Putyvl’ (1.01), Krasnopillia (1.02), Konotop (1.11), Buryn’ (1.32) districts and in the city of Sumy (1.15). These are the districts where the incidence rate of respiratory diseases among the population has increased most of all during the study period. Low values of IMI are noted in Lypova Dolyna (0.63), Seredyna Buda (0.71), Velyka Pysarivka (0.72) and Nedryhailiv (0.79) districts. The higher is the IMI value, the worse the health level of the population. The average index storage respiratory diseases (ISD) in the Sumy region in 2017 was 1.27, with polarization ISD value in some areas from 1.19 in Shostka, 1.22 in Konotop, 1.23 in Yampil’ and Trostianets regions to 1.39 in Lebedyn, 1.42 in Romny and 1.61 in the Seredyna Buda districts. This indicates the predomination of chronic forms of diseases over acute ones and can be explained by the influence of environmental and socio-economic factors. It also points to the need to increase of attention of both the regional and state components of the health care system. Besides that, the issues of providing financial and human resources for the health care system in districts with high incidence rates of respiratory pathology require attention. The study of the primary morbidity and the prevalence of respiratory diseases trends is a prerequisite for the development of preventive measures in the Sumy region. They are also needed to assess the quality of medical care for residents who have the pulmonary diseases. The factor analysis results are confirmed the importance of environmental and technogenic factors in formation of the indicators of primary morbidity and prevalence of respiratory diseases among the residents of the Sumy region.
