Modeling of sonographic parameters of the kidneys in practically healthy women of the middle intermediate somatotype depending on the constitutional parameters of the body

Abstract

The scientific literature presents quite a large number of works, in which the priority role of mathematical modeling in providing high-quality medical care, health and active longevity of a person is determined. The purpose of the work is to construct and analyze the regression models of individual sonographic sizes of kidneys in practically healthy women of the middle intermediate somatotype, depending on the features of the anthropometric and somatotypological indicators. Within the framework of the agreement on scientific cooperation from the database of National Pirogov Memorial Medical University, Vinnytsya primary sonographic parameters (length, width, anterior-posterior dimension, area of longitudinal and cross-section of the kidneys and their sinuses, as well as volume of the right and left kidneys) and anthropometric indices (obtained by the method of V.V. Bunak in the modification of P.P. Shaparenko) of 17 practically healthy women of the first mature age of the middle intermediate somatotype, who in the third generation live in the Podillya region of Ukraine. The construction of regression models of individual sonographic sizes of the kidneys, depending on the features of anthropo-somatotypological parameters of the body of women of the middle intermediate somatotype, was carried out in the licensed package “Statistica 6.1”. In women of the middle intermediate somatotype all 16 possible reliable regression models of sonographic parameters of the kidneys were constructed depending on the anthropo-somatotypological parameters with the determination coefficient R2 from 0.891 to 0.978. The analysis of reliable regression models (with a coefficient of determination greater than 0.6), the sonographic parameters of the kidneys in practically healthy women of the middle intermediate somatotype revealed that most often models of both kidneys, as well as separately of the right and left kidneys, include the circumferential dimensions of the body (respectively, 35.9 – 33.3 – 38.5% of the total number of indicators included in the models). In addition, models of both kidneys most often include cephalometric indices (12.6%), thickness of skin-fat folds and body diameters (by 11.7%); models of the right kidney – body diameters (15.7%), cephalometric indices and width of distal epiphyses of long tubular bones of extremities (by 11.8%); models of the right kidney - the thickness of skin and fat folds (17.3%) and cephalometric indices (13.5%). Attention is drawn to the lack of entry into models of sonographic sizes of kidneys total body sizes.

Manifestations of asymmetry and correlations of sonographic parameters of the kidneys with constitutional parameters of the body in practically healthy men and women of different somatotypes

“…The regression models of sonographic sizes of the kidneys, depending on the peculiarities of anthroposomatotypological parameters of the body of practically healthy men of mesomorphic, ecto-mesomorphic and endomesomorphic somatotypes, as well as practically healthy women of mesomorphic, ectomorphic, endo-mesomorphic and mean intermediate somatotypes were constructed and presented by us in the previous publications [5][6][7][36][37][38]. To analyze the asymmetry of entering the regression models of sonographic sizes of the anthropo-somatotypological indicators, we took into account all constructed reliable models, and not only models with a determination coefficient of greater than 0.6.…”

Modeling of appropriate spirometric indicators in practically healthy young women from Podillia with ectomorphic somatotype

“…The use of regression analysis makes it possible to create mathematical equations for determining the appropriate parameters of various organs and systems [3,11,18], in particular for spirometric forecasting, where predictors are anthropometric and somatotypological variables [4,7]. Despite the fact that there are separate works in which mathematical modeling of external breathing indicators is performed [1,8,15], this does not negate the expediency of such studies, especially for certain ethno-territorial population groups of a certain age, sex, health status, constitutional type, because it will make it possible to establish reference values of spirometric parameters.…”

“…At present, the conditionality of the macro-and microstructure of individual organs of various systems of the human body does not cause objections [8,19]. In addition, modern studies have proven the existence of a mutually determined relationship between the features of the external structure of the body and functional parameters [3]. But it should be noted that the majority of such studies focus on the cardiovascular system [10,11,13,18,20,23].…”

Investigation of Kidney Morphology and Somatotype Components in Early-Stage Kidney Patients

“…[ 7 ] In general, these studies aimed to develop prediction formulas by calculating the correlation or regression between body composition or various anthropometric parameters and organ sizes. [ 8 ] One study found a significant correlation between kidney size and body mass index and body weight. [ 9 ] Another study found an assignable variation between 11.8 and 22.4% between kidney sizes of healthy adult women and men with an endomesomorphic body type determined using somatotype components and multiple anthropometric parameters such as skinfold thickness and circumference measurements.…”
