PREDICTION OF INDIVIDUAL ULTRASOUND PARAMETERS OF THE SPLEEN, TAKING INTO ACCOUNT THE CONSTITUTIONAL CHARACTERISTICS OF MALES OF THE FIRST PERIOD OF ADULTHOOD IN THE DONETSK REGION

Abstract

The purpose of the work: to develop a mathematical model for predicting ultrasound parameters of the spleen depending on the anthropometric and constitutional characteristics of men of the first period of adulthood in the Donetsk region.
Materials and methods. The study involved 80 men aged 22 to 35 years. Anthropometry was performed, as a result of which the somatotype was determined using the Heath-Carter equations using somatocards (2002). Next, an ultrasound examination of the spleen was performed. After that, statistical processing and analysis of the obtained results were carried out using computer programs Microsoft Excel 2016 and Statistica 10 using parametric and nonparametric statistical criteria.
Results and discussion. According to the results of anthropometric measurements, the examined persons were divided into groups, depending on the somatotype, which was determined by the Heath-Carter method (2002). It was found that the following somatotypes predominate in the studied group of males: endo-mesomorphic (FOA) (35 people), ecto-mesomorphic (AOВ) (21 people) and meso-ectomorphic (BOC) (13 people). The frequency of occurrence of representatives of meso-endomorphic (EOF), endo-ectomorphic (COD), eto-endomorphic (DOE) and endomorphic balanced (VE) somatotypes turned out to be insignificant and totaled 11 people.
Further, the parameters of descriptive statistics of the values of anthropometric indicators and quantitative parameters of the spleen obtained by ultrasound examination were determined, which can be used as morphometric criteria of norm in representatives of various somatotypes of the first period of adulthood, taking into account gender. Statistical processing was used to determine the presence or absence of correlations between the anthropometric and somatotypological characteristics of the examined and ultrasound parameters of the spleen.
As a result of the study, a model was built for predicting one of the quantitative parameters of the spleen – the diameter of the splenic vein in the pancreatic body for men of the first period of adulthood in the Donetsk region of ecto-mesomorphic (AOВ) somatotype, depending on the following anthropometry indicators: the thickness of the skin-fat upper iliac fold and the transverse diameter of the distal part of the shin.
The equation of the multiple regression model for predicting the diameter of the splenic vein in the pancreatic body in men of ecto-mesomorphic (AOВ) somatotype has the form: Y= 0.33+ 0.61× X1 + 0.31× X2 (1), where Y is the diameter of the splenic vein in the body of the pancreas; X1 is the thickness of the skin-fat upper iliac fold, mm; X2 is the transverse diameter of the distal part of the tibia, cm.
The numbers before variables X1 and X2 are regression coefficients.
Conclusions. The proposed multiple regression equation can be used for diagnostic purposes in the daily practice of a medical professional to predict the diameter of the splenic vein in the pancreatic body in men of ecto-mesomorphic (AOВ) somatotype.
