Discriminant models of possibilities occurrence and features of the course of different forms of eczema in men depending on the characteristics of anthropometric indicators

Abstract

Eczema is a skin disease with a multifaceted clinical picture, numerous forms of manifestation and course and, last but not least, a life-modifying pathology that often requires lifestyle changes and reduces its quality. Identifying prognostic signs to predict the occurrence and severity of this disease is a priority for modern science. The purpose of the study is to build and analyze discriminant models of the possibility of occurrence and features of course of different forms of eczema in Ukrainian men of the first mature age depending on the characteristics of anthropometric parameters of the body. For men aged 22 to 35 years with true (n=34, including 16 mild and 18 severe) and microbial (n=38, including 28 mild and 10 severe) eczema, anthropometric examination according to the scheme of Bunak V.V. performed. Diagnosis of eczema was performed according to the nomenclature of ICD-10. The control group according to anthropometric data consisted of 82 practically healthy men of the same age, who were selected from the database of the research center of National Pirogov Memorial Medical University, Vinnytsya. Construction of discriminant models of the possibility of occurrence and features of the course of different forms of eczema depending on the anthropometric parameters of the body was carried out in the license package “Statistica 5.5”. It was found that the distribution of sick men on the truth of mild and severe eczema and microbial eczema of mild and severe course is possible only reliable interpretation of the obtained classification indicators between healthy and groups of patients (correct function in 76.0 % of cases, statistics Wilks’ Lambda = 0.074); when dividing sick men only into truth and microbial eczema – a reliable interpretation of the obtained classification indicators both between healthy and sick, and between sick truth and microbial eczema is possible (function is correct in 87.7 % of cases, Wilks’ Lambda statistics = 0.088); in the distribution of sick men only for mild or severe eczema – possible reliable interpretation of the obtained classification indicators between healthy and sick men, and between patients with mild or severe eczema only a slight tendency to interpret the obtained classification indicators (correct function in 84.4 % of cases, statistics Wilks’ Lambda = 0.088). In all cases, the constructed discriminant equations most often include the thickness of skin and fat folds (62.5 %, 57.1 % and 71.4 %, respectively) and body diameters (37.5 %, 42.9 % and 28.6 %, respectively). The obtained results confirm the prospects of using anthropometric research methods to predict the possibilities and features of eczema course and occurrence.
