Variability in the Incidence of Skin and Subcutaneous Tissue Diseases Among Children Aged 15–17 Years by Constituents of the Russian Federation (a Population-Based Study)

Abstract

Background. Taking into account the variability in the incidence of skin and subcutaneous tissue diseases among children aged 15–17 years by constituents of Russia is an important condition for optimizing pediatric dermatological care. According to modern literature, this issue has been underinvestigated.Our aim wasto study the nature of the variability in the incidence of skin and subcutaneous tissue diseases among children aged 15–17 years by constituents of the Russian Federation.Patients and Methods. State medical statistics for 83 constituents of the Russian Federation for 2009–2015 were used. The risk aggregation method was used in the study. The degree of morbidity variability by region was assessed by the range of variation and coefficient of variation. Subjects were ranked according to the annual incidence rate. To assess the sustainability of the subjects’ belonging to a certain rank place, the Spearman's rank correlation coefficient was used.Results.In 2009, the incidence of skin and subcutaneous tissue diseases among children aged 15–17 years in Russia had significant variability: the range of variation was 8.3 times, the coefficient of variation was 29%. Subjects were ranked by year. In 2010–2015, annual variability indicators remained high. Ranked places of subjects had rank correlation coefficients of 0.53–0.83 as compared to 2009. Groups of subjects with different levels of pediatric dermatological morbidity have been identified.Conclusion. The incidence of skin and subcutaneous tissue diseases among children aged 15–17 years by constituents of the Russian Federation during 2009-2015 was characterized by significant variability. Subjects had a stable belonging to a certain rank place. The constituents of the Russian Federation have been divided into groups according to the incidence rates for skin and subcutaneous tissue diseases.
