Skin and subcutaneous diseases were the 18th leading cause of global DALY in the Global Burden of Disease ranking in 2013. If we exclude mortality, skin diseases were the 4th most important cause of disability in the world [1]. They pose a serious problem for some countries [2, 3].
The incidence of skin and subcutaneous tissue diseases is high among students of the Kaliningrad anclave: they ranked 2–3 in ICD10 structure in 2012–2017 [4, 5].
The study aimed to assess the incidence of nosological forms of skin and subcutaneous tissue diseases in students of Kaliningrad anclave.
We analyzed nosological forms of primary skin and subcutaneous tissue diseases under ICD-10 in cadets of two higher military educational institutions in 2012–2017. The levels of incidence per 1 thousand people (‰), structure ( %), and long-term trends were determined. We compared the incidence recorded in each year.
Data on primary incidence were obtained at copying from the medical cards of a patient under ambulatory medical care (file No. 025/u): n1 = 1127, n2 = 671.
The reliability of differences was determined by the Student’s t-test for mean values and mean errors (M ± m). We determined the reliability of differences (d) between the incidence indicators of the given training year with the indicators of the next one. The primary data were processed using the computer program Statistica 6.1.
Three groups of diseases were identified among all the skin and subcutaneous tissue diseases in cadets (Table 1). The share of the group «infections of skin and subcutaneous tissue» (L00‑L08) in each observation object accounted 80.4 and 73.9 %, respectively; the group «dermatitis and eczema» (L20 — L30) — 18.2 and 20.3 %; the group «other skin and subcutaneous tissue diseases» (L80 — L99) — 1.4 and 5.8 %. Hence, the primary incidence was 2.8 and 2.3 times, respectively, greater than the one in University No.2 for the first two groups in University No.1; on the contrary, it exceeded 1.6 times in University No.2 for the third group.
