Features Of Anthropometric Indicators Of Children Of The First Year Of Life Born Of Mothers In The State Of Hypothyrozis

During pregnancy, all organs of the mother work more intensely, since they have to be responsible for the vital activity of not only the mother, but also the child. This also applies to the thyroid gland, which provides hormones to both mother and baby until he has formed his own endocrine system. The vital hormones for both are the thyroid hormones thyroxine (T4) and triiodothyronine (T3). A lack of these hormones, called hypothyroidism, can affect both the course of pregnancy and the health of the expectant mother and her baby. However, with constant medical supervision, pregnancy and natural childbirth with hypothyroidism are quite real. With full control and following all the recommendations of doctors, pregnancy and childbirth with hypothyroidism will go well.


INTRODUCTION
Relevance of the topic. Children's health is a complex indicator, the formation of which, according to the World Health Organization, should be considered in unity with the health of the mother and the state of the external environment [WHO, 2007]. One of the leading factors that ensure the physical, mental, intellectual development of the child is adequate provision with microelements,  ]. The provision of the population with iodine is determined not only by the region of residence, but also by the lifestyle, food culture. The iodine requirement of a breastfed baby in the first year of life depends on the mother's health, nutrition, and iodine prophylaxis.
Numerous studies devoted to the study of the health of children in an iodine-endemic region concern mainly children of

PURPOSE OF THE STUDY
To identify some indicators of anthropometric development of the fetus and their change in dynamics in pregnant women in a state of hypothyroidism using ultrasound screening examination.

METHODOLOGY AND RESEARCH METHODS
The studies were carried out on the basis of the 2nd clinic of SamMI, in compliance with all the necessary ethical and deontological standards. The work is based on the analysis of standard fetometric parameters (binarietal size, frontal-occipital size, head circumference, abdominal circumference, femur length -studied on a retrospective analysis of case histories), as well as additional research on the dimensional characteristics of the fetal thymus. Standard fetometry indices

RESEARCH RESULTS AND THEIR DISCUSSION
According to the obtained results of significant differences in fetometric parameters in healthy fetuses and fetuses in pregnant women in a state of hypothyroidism at the stages of screening examination of pregnant women, the following indicators were revealed. The main fetometric indicators are presented in Table 1. According to our data for different periods of pregnancy, fetuses from healthy pregnant women increased their body length by 1.5 cm and in pregnant women in a state of hypothyroidism by 0.4 cm. Fetuses in pregnant women in a state of hypothyroidism during studies almost did not change their weight, fruits from healthy pregnant women, increased body weight by 0.8 kg. The binarietal size in pregnant women in a state of hypothyroidism remained unchanged, in fetuses from healthy pregnant women, the spirometry index increased by 0.27.  Table 2. From the results during the observation process, it follows that this age period is characterized by some slowdown in growth rates. The most intense changes were noted during the last periods of the development of weeks of intrauterine development of the fetus, both in healthy and in pregnant women with hypothyroidism. In general, the binarietal size in fetuses from healthy mothers increased by 1.8 cm (11.2%), in fetuses in hypothyroid women -by 0.86 cm (4.42%). However, fetuses from healthy mothers have higher growth rates compared to the constants of physical development [3], according to which, in fetuses from healthy mothers, growth gains vary from 1.6 cm at 30-31 weeks to 1.7 cm at 34-35 weeks ... In fetuses of pregnant women in a state of hypothyroidism, growth rates do not differ from constants from 0.8 cm at 30-31 weeks to 1.1 cm at 34-35 weeks.
The increase in abdominal circumference and head circumference was 1.9 cm in fetuses from healthy mothers and 1.07 cm in fetuses of pregnant women in hypothyroidism (22.2% and 3.02%, respectively). During fetal development of the last trimester, fetuses are characterized by a gradual increase in the circumference of the abdomen and head. In our case, the increase occurs, but small, especially in fetuses from healthy mothers.
The assessment of the level and harmony of physical development was carried out using indices, the average group values of which are shown in Table 2.
The  The especially significant role of thyroid hormones for the processes of growth and differentiation of tissues, primarily of nervous tissue, has determined the need to study the state of health, physical and neuropsychic development of children with neonatal transient hypothyroidism.
