The article analyzes the data of an anthropometric and somatotypological study of 164 boys and 93 girls of the northern region, different sexual somatotypes with different severity of signs-phenes of undifferentiated connective tissue dysplasia. It was found that 44% of boys and 22% of girls with d, according to sexual somatic differentiation, correspond to the biological sex, 34% of boys and 53% of girls have mild gender dysplasia in the form of mesomorphy, and 19% of boys and 21% of girls have signs of sex inversion. Undifferentiated connective tissue dysplasia affects the severity of morphotypological differences between sexual somatotypes and the appearance of signs of gracialization within them. Key words: northern region, adolescence, sexual dimorphism, undifferentiated connective tissue dysplasia.

Abstract. In connection with the spread of undifferentiated forms of connective tissue dysplasia (UCTD) in unfavorable climatogeographic and environmental conditions, it seems relevant to assess the impact of organogenesis disorders on physical development in schoolchildren living in the northern region. Based on the foregoing, the purpose of this study was to study the relationships and interdependencies of the components of physical development and somatometric indicators in children of the northern region with phenotypic signs of connective tissue dysplasia. Anthropometric indicators were revealed that can be used for express diagnostics of the level of physical development in children with UCTD these are the length of the legs, the thickness of the skin-fat fold on the front surface of the shoulder and the interorbital-circumferential index. When assessing covariants such as age and sex, there is a correlation of clusters of long-length values with age, the relationship of the thickness of the skin-fat folds with the floor, and the parameters assessing changes in the cerebral and facial skull, such as: face width, head circumference and interorbital-circumferential index are associated with both sex and with age. The influence of posture disorders on the studied components of physical development is manifested by higher growth in children with flat and round-curved backs, a decrease in the thickness of skin-fat folds and head size with a round and round-curved back. Thus, for a comparative analysis of gender and age differences in the level of physical development in children with UCTD, it is necessary to take into account the dynamics of interdependent anthropometric indicators and indices, taking into account postural disorders.

The article presents the results of assessing the physical development of children 7–17 years old in the northern region with undifferentiated connective tissue dysplasia. It has been established that undifferentiated connective dysplasia affects the degree of harmony of physical development and the formation of pathological types of posture depending on gender and age, but does not affect gender and age differences in the rates of physical development.

The article analyzes the data of anthropometric and somatotypological studies of 164 boys and 174 girls of the Khanty-Mansi Autonomous Okrug – Yugra, of diff erent sex somatotypes. It was found that 44% of boys and 15% of girls, according to sexual somatic diff erentiation, correspond to the biological sex, 40% of boys and 58% of girls have mild gender dysplasia in the form of mesomorphism, and 21% of boys and 27% of girls have signs of sex inversion. In young men from the northern region, clear sexual dimorphism anthropometric parameters were revealed. In girls of the Khanty-Mansi Autonomous Okrug – Yugra of diff erent sex somatotypes, no statistically signifi cant diff erences were found in most anthropometric parameters, which is associated with the general tendency of their somatic profi le to asthenization and masculinization

The Impact

Due to the spread of undiff erentiated forms of connective tissue dysplasia, it seems relevant to assess the impact of organogenesis disorders on the physical development of schoolchildren living in the northern region. What dictates the need to study the interrelationships and interdependencies of the components of physical development and somatometric indicators in children of the north with phenotypic markers of UCTD. The eff ect of posture disorders on the studied components of physical development is manifested by higher growth in children with a fl at and round-concave back, a decrease in the thickness of skin-fat folds and the size of the head with a round and round-concave back. Therefore, to analyze the intersex and age diff erences in physical development in children with NDT, it is necessary to take into account the dynamics of interdependent anthropometric indicators and indices, taking into account the types of posture disorders.

The Impact

Background. Assessment of the physical development of children in individual regions of the Russian Federation does not lose its relevance and requires constant updating, in this regard, it is important to study it in children adapting to the climatic and geographical conditions of the North, as well as the effect of undifferentiated connective tissue dysplasia on it. Aim. Aim of the study is to study the gender and age characteristics of the proportionality of physical development in children with undifferentiated connective tissue dysplasia living in the Khanty-Mansiysk Autonomous Okrug Yugra. Materials and methods. The analysis of physical development of 528 children of the second childhood and adolescence, living in the Khanty-Mansi Autonomous Okrug Yugra, was carried out. The study group consisted of 342 children (248 boys and 94 girls) with a diagnostically significant number of undifferentiated connective tissue dysplasia symptoms (from 6 to 18 stigmas). The comparison group included 186 children (111 boys and 75 girls) who did not score a significant threshold of phene signs (from 0 to 5 stigmas). Physical development was assessed according to the Quetelet II weight-height index, chest-weight indices: Pignet, Vervek, and Brugsch, as well as proportionality indices: sternum, shoulder width, pelvic width, torso shape, arm and leg length indices, cranial and facial indices, interorbital-circular index. Results. Children without undifferentiated connective tissue dysplasia during the second childhood have a tendency to malnutrition, and are characterized by a weak physique with a tendency to narrow chest. In adolescence, the tendency towards weakness of the physique persists, while height-weight ratios deviate towards normotrophy. Children with undifferentiated connective tissue dysplasia during the second childhood and adolescence have a rectangular or trapezoidal body with an average length, as well as long upper and lower limbs relative to the length of the body. Conclusion. The impact of the socio-ecological factors of the North neutralizes the differences in the rates of physical development in healthy children and persons with disorders caused by congenital disorders of organogenesis of the undifferentiated connective tissue dysplasia type.

Undifferentiated forms of DST are widespread among children living in Khanty-Mansiysk, in connection with which it is relevant to assess the influence of this pathology on the formation of posture in schoolchildren of the North. Determination of the type of posture and the identification of stigmas of dysembryogenesis was carried out in 208 schoolchildren of the city of Khanty-Mansiysk. Posture types were divided into: normal, round, flat and stooped. Participants with the number of stigmas from 0 to 5 were allocated to the comparison group (n = 66), the rest (6 or more) made up the study group (n = 143). A card was entered, including 43 hair dryers. The study found that the incidence of UCTD among children in the Khanty-Mansi Autonomous Okrug-Yugra is noticeably higher than among those living in temperate latitudes and has a negative effect on the formation of posture. Key words: North, posture, physical development, undifferentiated connective tissue dysplasia.

As a result of the study, it was found that 94.4% of boys and girls of Khanty-Mansi Autonomous Okrug – Ugra have signs of dysmorphogenesis of hard and soft tissues of the head. In 76% of the examined, connective tissue dysplasia was established. In representatives with connective tissue dysplasia, the signs of dysmorphogenesis of the facial and brain parts of the head are only combined, have sexual dimorphism and are very diverse, aff ecting all areas of the brain and facial parts of the head. The presence of a dysplastic phenotype does not aff ect individual dimensional characteristics of the brain and facial parts of the head, but it aff ects the morphotypological characteristics of these departments and their gender diff erences.
