INCIDENCE OF PSORIASIS DEPENDING ON THE REGION OF THE RUSSIAN FEDERATION

The article presents the results of a study on assessment the differences of psoriasis incidence in adults in regions of the Russian Federation. The indicators of general and primary incidence of psoriasis were used as the material for a study according to the data from Central Research Institute of Health Organization and Informatics of the Ministry of Public Health of the Russian Federation for the period 2009-2013. The comparative results of psoriasis prevalence among adults population in various regions in Russia were presented. Higher incidence rate was detected in the northern and northeastern regions of the North-Western, Volga, Ural, and Far Eastern regions. The results of classification for the regions of the Russian Federation according to the data of primary and general morbidity were presented. In order to establish the peculiarities of pathology formation and assess the quality of information in the regions of the Russian Federation, a multidimensional classification of the incidence of psoriasis was carried out using the cluster analysis method, using the comparison of prevalence (general morbidity) with primary incidence data for the period 2009-2011. As a result of the cluster analysis, four classes of the country regions are distinguished, the differences between which are statistically significant for all classification characteristics. The average indices of both primary incidence and prevalence of psoriasis are registered in regions of Class 1 (27 subjects of the Russian Federation). The minimum indices of primary and general incidence of psoriasis were noted in class 2 (24 subjects of the Russian Federation), which comprised regions predominantly of the Central, Southern, Siberian FD. The highest rates of primary incidence and prevalence of psoriasis were found in the group of regions that made up Class 4 (14 subjects of the Russian Federation), in a third of the regions of this class - Orel and Sverdlovsk regions, Udmurt Republic, Komi Republic and Sakha (Yakutia), data, unsatisfactory dispensary observation of patients with psoriasis. A certain decrease in the availability of specialized dermatological care can be expected in Class 3 regions, where the primary incidence is low, and the prevalence is above the average (18 subjects of the Russian Federation).
