Age and Spatial Peculiarities of Non-neoplastic Diseases of the Skin and Subcutaneous Tissue in Kazakhstan, 2003–2015

Background Arrangement of effective management aimed at improving dermatological services and consistent care of patients with skin diseases depends on understanding the epidemiological situation. Methods This retrospective study presents an epidemiological assessment of non-neoplastic skin and subcutaneous tissue diseases in Kazakhstan registered in 2003-2015. Results The yearly incidence rate of the diseases among the whole population was in average 3,341.8±121.1 per 100000 population. This represents 4835.0±156.1 for children, 5503.2±141.8 for adolescents and 2646.6±106.7 for adults per 100000 inhabitants. Space and time incidence rate was evaluated according to the administrative division. The overall trend decreased to 3.5% in children to 2.8% in adolescents to 1.9%, and in adults to 3.9%. Considerable variation in rates was seen across the country, with highest rates in East Kazakhstan, Mangystau and Aktobe regions, the lowest - in Atyrau and South-Kazakhstan regions. Conclusion Non-neoplastic diseases of skin and subcutaneous tissue continue to be an urgent public health problem, especially among children in many regions of Kazakhstan.
