COMPARATIVE CHARACTERISTICS OF THE SIZES OF THE THYROID GLAND AND THE PARAMETERS OF THE PHYSICAL DEVELOPMENT OF CHILDREN 11 AND 12 YEARS OF AGE

Abstract

To conduct a comparative characteristic of the size of the thyroid gland and the parameters of physical development of children of 11 and 12 years of age. The study examined the morphometric parameters of the thyroid gland and anthropometric parameters in 11-year-old and 12-year-old boys and girls (n = 80). We tried to establish the average value of the normal volume of the thyroid gland and find out whether there is a relationship between the volume of the organ and the parameters of physical development. Studies have shown that in boys of 11 and 12 years old included in our group, the growth rate of parameters of physical development and morphometric parameters of the thyroid gland is less than in girls of the same age. On the basis of the data obtained, it was established that the physical development of 11 and 12-year-old boys, in comparison with girls, tends to lag behind. The prevalence of height and body weight in girls compared with boys is possibly associated with the early onset of their puberty. Anatomical parameters of the thyroid gland (length, width, volume) in boys of 11 and 12 years of age lag behind in comparison with girls of the same age.
