The success of the solution to the problem of treatment and prevention of obstetric-gynecological pathology largely depends on the extent to which the relationship between the sonographic sizes` of the uterus and the ovaries with the constitutional parameters of the body will be fully and systematically studied. The purpose of the work is to establish differences in correlations of ultrasonic sizes of the uterus in different phases of the menstrual cycle (MC) with anthropo-somatotypological parameters of the body of practically healthy young women of ecto- and mesomorphic somatotypes. Primary indices of sonographic sizes of the uterus, as well as anthropometric and somatotypological parameters in 78 healthy urban young women of Podillia with duration of MC 28 days were obtained from the data bank of the research center of the National Pirogov Memorial Medical University, Vinnytsya. In a sonographic study in different phases of the MC, the length and width of the body, the length of the neck and the anterior-posterior size (thickness) of the uterus were measured for its largest size, as well as the thickness of the endometrium and myometrium. According to Bunak V. V. scheme anthropometric survey was conducted. The evaluation of the somatotype was carried out using the Carter-Heath mathematical scheme. According to the formulas of J. Matiegka fat, bone and muscle mass components are determined, and according to the American Institute of Nutrition, the muscular component of the body mass. The analysis of the correlations of the obtained results was carried out in the licensed package “Statistica 6.1” with the use of nonparametric statistics of Spearman. In young women with mesomorphic somatotype, regardless of the phase of MC, in most cases, there are numerous, mostly direct, reliable and unreliable mean strength correlations between the linear size of the uterus, the length of the cervix and the thickness of the myometrium, and most of the total and longitudinal dimensions of the body, as well as between the length of the body of cervix and the width of the distal epiphyses of the upper limb, the majority of the lower limbs girth, the thickness of the skin-fat folds on the lower extremity, and practically all the components of the body weight by Matiegka. In young women with ectomorphic somatotype, regardless of the phase of the MC, numerous, mostly direct, reliable average forces and strong and unreliable mean strength connections between all echometric dimensions of the uterus and all total, most of the longitudinal dimensions of the body (with the exception of the thickness of the endometrium), the width of the distal epiphysis forearm, most of the girth dimensions, shoulder width and muscle mass components of the body using the Matiegka method and the American Institute of Nutrition are set. Attention is drawn to the average strength, mostly reliable, feedback correlations regardless of the MC phase, between all echometric dimensions of the uterus and the ectomorphic component of the somatotype. So, between young women of meso- and ectomorphic somatotypes set differences of numerous connections of the sonographic parameters of the uterus with anthropo-somatotypological indices. In young women of mesomorphic somatotype in the follicular phase of the MC, the ovulation phase, and the luteal phase of the MC, the number and strength of the connections of the sonographic sizes of the uterus with anthropomorphic somatotypological parameters is lower than that of the representatives of the ectomorphic somatotype.

It is known that both genetic factors and environmental influences affect the development of the human body. This statement also applies to a person’s personality, ie the big five – the main features that make it up. The study of the relationship between physique and personality traits among a healthy population is very relevant and is a promising area for anthropology and psychology. The purpose of the work is to conduct a prognostic assessment of the influence of anthropo-somatotypological indicators on the personality indicators in practically healthy Ukrainian women without and taking into account the somatotype. Primary anthropo-somatotypological (anthropometry according to Bunak’s scheme, Heath-Carter somatotype determination, Matiegka and American Institute of Nutrition weight composition) and personality indicators (determination of leading typological characteristics of temperament according to Eysenck, psychodynamic features of personality according to Spielberger and features of accentuated personality traits according to Shmishek, components of internality according to Rotter) of practically healthy Ukrainian women of the first mature age are selected from the data bank of materials of the research center of National Pirogov Memorial Medical University, Vinnytsya. Factor analysis was performed in the license package "Statistica 6.1". The main factors that indicate the association of personality traits of practically healthy Ukrainian women of different somatotypes with some anthropo-somatotypological indicators: mesomorphs – "the size of the girth and fat size of the body" and "the size of the longitudinal size of the body"; in ectomorphs – "the size of the girth of the body" and "the size of the fat size of the body"; in endo-mesomorphs - "the magnitude of the circumferential size of the body" and "the magnitude of the width of the mandible"; in representatives of the middle intermediate somatotype – "the magnitude of the longitudinal and circumferential dimensions of the body" and "the magnitude of SFT on the posterior surface of the shoulder." In the general group of women, it is impossible to single out the second factor that has a significant load. Analysis of the obtained relationships of interdependence of personality traits, which have the greatest prognostic value in terms of formation of human personality with anthropo-somatotypological indicators showed that women of different somatotypes identified interdependencies have certain features. Thus, the application of factor analysis made it possible to determine the most significant relationships of personality indicators with the constitutional parameters of the body in practically healthy Ukrainian women of different somatotypes.

The human body has been shaped by natural selection during the past 4–5 million years. Fossils preserve bones and teeth but lack muscle, skin, fat, and organs. To understand the evolution of the human form, information about both soft and hard tissues of our ancestors is needed. Our closest living relatives of the genusPanprovide the best comparative model to those ancestors. Here, we present data on the body composition of 13 bonobos (Pan paniscus) measured during anatomical dissections and compare the data withHomo sapiens. These comparative data suggest that both females and males (i) increased body fat, (ii) decreased relative muscle mass, (iii) redistributed muscle mass to lower limbs, and (iv) decreased relative mass of skin during human evolution. Comparison of soft tissues betweenPanandHomoprovides new insights into the function and evolution of body composition.

Prediction of the occurrence of eczema and the development of its severe forms is possible by identifying its morphological markers in patients with various forms and severity of dermatosis and their comparison with healthy subjects. The aim of the study was to examine the differences in body girth sizes between healthy and/or eczema patients depending on the severity of dermatosis. Patients with idiopathic (n=34) and microbial (n=38) eczema men of the first mature age underwent an anthropometric examination according to Bunak. The diagnosis of eczema was made according to the nomenclature of ICD-10. As a control from the data bank of the research center of National Pirogov Memorial Medical University, Vinnytsya anthropometric data of 82 practically healthy men of the same age group were selected. Statistical data processing was performed in the license package “Statistica 5.5” using non-parametric methods of evaluation of the obtained results. In healthy men, the following values of the following envelope sizes were found: shoulder girth in a tense state by 4.9 % compared with patients with severe eczema; unstressed shoulder girth by 7.3 % and 11.8 % compared with patients with idiopathic eczema of mild and severe course and by 10.0 % and 11.3% compared with patients with microbial eczema of mild and severe course; forearm girth in the upper part by 5.4 % compared with patients with idiopathic eczema of severe course; thigh girth by 5.1 % and 8.0 % compared with patients with idiopathic eczema of mild and severe course and by 7.1 % and 11.3 % compared with patients with microbial eczema of mild and severe course; thigh girth by 4.16 % and 4.5 % compared with patients with idiopathic severe eczema and mild microbial eczema; upper crus girth by 5.3 %, 7.5 % and 7.1 % compared with patients with idiopathic eczema of mild and severe course and microbial eczema of mild course; lower crus girth by 6.0 % compared with patients with mild microbial eczema; neck girth by 7.5 % and 6.8 % compared with patients with idiopathic severe eczema and mild microbial eczema; waist girth by 8.6 % and 15.6 % compared with patients with idiopathic eczema of mild and severe course and by 13.9 % and 16.7 % compared with patients with microbial eczema of mild and severe course; chest girth on inhalation, exhalation, at rest by 6.9 %, 9.5 % and 9.1 % compared with patients with idiopathic eczema of severe course. Only the girth of the foot in healthy men is 3.1 % higher than in sick men with mild microbial eczema. In men with idiopathic eczema, the neck girth was 5.4 % lower than in men with severe eczema. The obtained data can be used for a personalized approach in the creation of appropriate prevention and treatment and diagnostic programs.

O objetivo foi verificar a influência do excesso de peso na força muscular e na funcionalidade de tronco de mulheres jovens. Estudo analítico transversal, com 54 mulheres de 18 a 30 anos, com excesso de peso (n=25), e eutróficas (n=29). A força muscular de tronco foi avaliada pelo dinamômetro isocinético e a funcionalidade de tronco e membros inferiores através do Bunkie Test. A análise dos dados foi realizada por meio do programa SPSS (Sciences Statistical Package for the Social Sciences). Como resultado, o presente estudo identificou que as mulheres com excesso de peso conseguem gerar pico de torque absoluto na 1º série (p=0,023), na 2º série (p=0,009), e no impulso na 2º série (p=0,009) maiores que as mulheres eutróficas. No entanto, quando o pico de torque foi analisado proporcionalmente ao peso corporal, estes valores foram menores, não sendo encontrada diferença entre os grupos (p0,05). Para o Bunkie Test, o grupo com excesso de peso apresentou pior desempenho na funcionalidade, principalmente nos movimentos de extensão, em decúbito dorsal, dos membros inferiores direito (p=0,011), esquerdo (p= 0,004) e na manutenção do tronco em decúbito lateral direito (p=0,008). Conclui-se que o excesso de peso pode alterar diretamente a força muscular e interferir na funcionalidade de tronco de mulheres jovens, sugerindo um desequilíbrio muscular em tronco e membros inferiores.Palavras-chave: Força Muscular. Obesidade.

This is a cross-sectional analytical study that was conducted with 54 women aged 18 and 30 years – twenty-five (25) were overweight and twenty-nine (29) were eutrophic. Muscle strength was assessed by an isokinetic dynamometer, whereas functionality was assessed by the Bunkie Test. Data analysis was performed using the SPSS program (Sciences Statistical Package for the Social Sciences). As a result, the present study identified that overweight women can generate absolute peak torque in the 1st grade (p = 0.023), in the 2nd grade (p = 0.009), and in the 2nd highest grade (p = 0.009) than eutrophic women. However, when the peak torque was analyzed proportionally to the body weight, these values were lower, and no difference was found between the groups (p 0.05). For the Bunkie Test, the overweight group presented worse performance in the functionality, especially in the extension movements, in the dorsal decubitus position, of the right lower limbs (p = 0.011), left (p = 0.004) and in the maintenance of the decubitus trunk right side (p = 0.008). It is concluded that overweight can directly affect muscle strength and interfere with the trunk function of young women, suggesting a muscle imbalance in the trunk and lower limbs.Keywords: Muscle Strength.

Secondary amenorrhea is a menstrual cycle that occurs in women who have menstruated but does not increase menstruation within 3-6 months. The key to the menstrual cycle depends on changes in estrogen levels. Soybeans are the main source of phytoestrogens which play a role in stabilizing estrogen levels in the body, whereas 250 ml of soy milk contains 40 mg of phytoestrogens. The purpose of this study was to determine how to consume soy milk against changes in secondary amenorrhea in young women. This research is a descriptive-analytic conducted cross-sectionally. This type of research is an easy experiment with a non-randomized posttest group design. The research sample is young women who change secondary amenorrhea which is grouped into 2 groups of 17 people each. Data collection was conducted from August 2 to October 19, 2016. The statistical test used was the Wilcoxon test. The results showed that normal menstruation occurs in secondary amenorrhea adolescents after being given soy milk which is equal to 82.4% while in adolescents who are given sweetened condensed milk only by 29,4%. Statistical tests show the results of p= 0,002. The conclusion, there is a change in secondary amenorrhea between the samples gave soy milk, and those given sweetened condensed milk. Suggestions, it is necessary to provide a daily menu for students so that the menstrual cycle is maintained.

Nevi, although benign neoplasms of the skin, but have a certain tendency to malignancy, which is influenced by various external and internal human factors. Predicting the risk of benign nevi against this background is an important topic for experimental research. The aim of the study was to establish the features of the skinfold thickness (SFT) in men of the first adult age with benign nevi. SFT was determined according to the Bunak scheme for men (aged 22-35 years) with melanocyte benign simple nevi (n=34), melanocyte benign dysplastic nevi (n=27), melanocyte benign congenital nevi (n=14) and non-melanocyte benign (n=17). The control group – SFT of 82 practically healthy men of the same age group was selected from the data bank of the Research Center of National Pirogov Memorial Medical University, Vinnytsya. Statistical processing of the results was performed in the license package “Statistica 5.5” using non-parametric evaluation methods. It was found that in practically healthy men higher than in patients – SFT on the anterior and posterior surfaces of the shoulder and thigh (in all groups of patients); SFT on the forearm, at the lower angle of the scapula, chest and shin (only in patients with melanocyte benign dysplastic nevi). Also in healthy men are found lower than in patients – SFT on the side (in all groups of patients); SFT in the abdomen (in patients with melanocyte benign simple and non-melanocyte benign nevi). When comparing SFT between patients with benign nevi, in most cases, lower values of SFT found in patients with melanocyte benign dysplastic nevi. The obtained results indicate the initial manifestations of abdominal (android) type of fat deposition in the body in patients with benign nevi (most pronounced in patients with melanocyte benign simple nevi).

Annotation. The constitutional approach is a valuable tool in the hands of practicing dermatologists, which allows an individual approach to the diagnosis and treatment of patients with psoriasis. The aim of the study was to examine the differences in total, longitudinal and transverse body sizes between healthy and/or psoriatic men depending on the severity of the disease. Anthropometric examination according to Bunak was performed for 32 men of the first mature age in patients with mild and 68 men with severe psoriasis. The PASI index was used to clinically assess the severity and area of psoriatic lesions. As a control from the data bank of the research center of National Pirogov Memorial Medical University, Vinnytsya anthropometric data of 82 practically healthy men of the same age group were selected. Statistical data processing was performed in the license package “Statistica 5.5” using non-parametric methods of evaluation of the obtained results. In patients with mild and severe psoriasis compared with healthy men found: lower values – pubic height (by 3.2 % and 5.4 %) and trochanter (by 8.2 % and 7.0 %) anthropometric points, shoulder width (by 19.6 % and 19.0 %) and the width of the distal epiphysis of the shin (by 5.2 % and 4.8 %); greater values – body weight (by 20.1 % and 17.5 %), body length (by 1.7 % in mild course), body surface area (by 10.0 % and 7.8 %), height of suprasternal (by 3.0 % and 1.5 %), acromial (by 2.3 % and 1.0 %) and finger (by 6.1 % and 4.4 %) anthropometric points, width of the distal epiphysis of the shoulder (by 6.9 % and 5.7 %), forearm (by 3.3 % in mild course) and thigh (by 10.3 % and 7.1 %), mid-thoracic diameter (by 16.5 % and 16.3 %), transverse lower thoracic diameter (by 16.5 % and 15.7 %), anterior-posterior mid-thoracic diameter (by 17.7 % and 20.2 %), interspinous (by 12.2 % and 12.1 %), intercristal (by 13.4 % and 11.7 %) and intertrochanteric (by 11.3 % and 10.4 %) distances. Differences in the studied body size in patients with varying degrees of psoriasis found. Thus, in patients with mild psoriasis, compared with patients with severe psoriasis, higher values were found for: body length (by 1.6 %); heights of suprasternal (by 1.5 %), pubic (by 2.1 %) and finger (by 1.4 %) anthropometric points; width of the distal epiphysis of the forearm (by 2.3 %). Thus, pronounced differences in total, longitudinal and transverse dimensions between healthy and patients with mild and severe psoriasis were revealed by Ukrainian men of the first mature age. Between patients with varying degrees of severity of dermatosis, most differences are found only for longitudinal body size.

Background:Reproductive health is an important part of the health program. Several diseases that related to the reproductive system are important things to be solved such as irregular menstrual cycles. Some factors that affect the menstrual cycle are the influence of weight, physical activity, and the process of ovulation and adequate luteal function. Now, special attentions arealso emphasized on the diet behavior and stress.  The purpose of this study was to know the correlation of Body Mass Index (BMI) and stress level with menstrual cycle of young women in SMK WidyaUtama Indramayu. Methods: The design of this study used an analytic survey using a cross sectional design. The instrument used is the questionnaire of Depression Anxiety Stress Scale (DASS) that has been standardized and modified. questionnaire for measuring the menstrual cycle is a question about the menstrual cycle. Body mass index (BMI) is measured by calculating body weight / TB2 in kg / m2. Result: The results showed that the Body Mass Index in Normal category (68.3%), stress level in the normal category (68.3% and menstrual cycle in the normal category (56.7%). There was a significant relationship between body mass index and cycle menstruation with a value of p = 0.000 There is a significant relationship between stress levels with the menstrual cycle with a value of p = 0.031. Conclusion: that need to be recommended are the need to control the weight so that the nutritional status will be in the ideal level, able to adapt the stress and regularly record the menstrual period in order to control the menstrual cycle.

Determination of constitutional parameters that are inherent in highly skilled athletes of a particular sport can serve as reliable predictive markers during sport selection. But the last time an indisputable fact is the somatotypological conditionality of individual sizes that characterize the external structure of the body, and the visceral structures of the organism. The purpose of the work is to establish differences in the anthropometric dimensions between young women volleyball players of high level of athletic skill and non-sports young women belonging to the mesomorphic somatotype. On the base of the research center of the National Pirogov Memorial Medical University, we conducted an anthropo-somatotypological study of 127 female volleyball players of youth age (from 16 to 20 years) with a high level of athletic skill. Sports experience in all cases was greater than 3 years. From the database of research center of the National Pirogov Memorial Medical University was selected 140 practically healthy young women of the same age who were not engaged in sports. Anthropometric measurements were carried out using the method of V.V. Bunak (1941), somatotypological research – according to the estimated modification of the Heath-Carter method (1990). After the conducted somatotyping, it was found that 29 volleyball players and 33 non-sports young women belonged to the mesomorphic type of constitution. The analysis of the obtained results is carried out in the licensed package of Statistica 5.5 using nonparametric methods of evaluation of indicators. In the volleyball players of the mesomorphic somatotype, compared to young women who are not engaged in sports of the same constitutional type, we have found a significantly larger length of the body, the mass and area of the body surface, the height of the suprasternal, pubic, shoulder anthropometric points, chest cords, transverse mid and lower chest and sagittal middle-thigh diameters, intervertebral distance of the pelvis and its external conjugates. Relatively smaller in female volleyball players of mesomorphic type of physique was the thickness of the skin-fat folds under the shoulder blade. One can conclude that within the same somatotype there are significant changes in the anthropometric parameters, in particular total body and longitudinal, transverse, front and rear body dimensions, which is affected by the body of modern young women volleyball players with mesomorphic somatotype, under the influence of intensive loads.

Body temperature and sleep change in association with increased progesterone in the luteal phase of the menstrual cycle in young women. The mechanism by which progesterone raises body temperature is not known but may involve prostaglandins, inducing a thermoregulatory adjustment similar to that of fever. Prostaglandins also are involved in sleep regulation and potentially could mediate changes in sleep during the menstrual cycle. We investigated the possible role of central prostaglandins in mediating menstrual-associated 24-h temperature and sleep changes by inhibiting prostaglandin synthesis with a therapeutic dose of the centrally acting cyclooxygenase inhibitor acetaminophen in the luteal and follicular phases of the menstrual cycle in young women. Body temperature was raised, and nocturnal amplitude was blunted, in the luteal phase compared with the follicular phase. Acetaminophen had no effect on the body temperature profile in either menstrual cycle phase. Prostaglandins, therefore, are unlikely to mediate the upward shift of body temperature in the luteal phase. Sleep changed during the menstrual cycle: on the placebo night in the luteal phase the women had less rapid eye movement sleep and more slow-wave sleep than in the follicular phase. Acetaminophen did not alter sleep architecture or subjective sleep quality. Prostaglandin inhibition with acetaminophen, therefore, had no effect on the increase in body temperature or on sleep in the midluteal phase of the menstrual cycle in young women, making it unlikely that central prostaglandin synthesis underlies these luteal events.
