The result of studying some morphometric parameters of the thymus in Mongolian children

Abstract

Background: The World Health Organization recommends an anthropometric program based on weight and age to assess the growth and development of children every 5-10 years. It is still one of the pressing problems of medical anthropology, which is essential for the comprehensive assessment of children’s health status, prevention, and improvement of health. In our country, researchers Tuul M (2004) and Erdenezaya O (2007) have not yet found other studies on the morphometric parameters of the thymus, which is the reason for conducting this research. Aim: To study the gross and microstructure of the thymus in Mongolian children aged 0-14 years. Materials and Methods: We conducted this study using a cross-sectional survey design. In doing so, the research material was randomly selected from a total of 255 cases of 0-14 years old who died of non-endocrine causes in the NICU. Results: The children aged 0-14 who participated in the study were divided into 9 groups (0-30 days, 1-3 months, 4-6 months, 7-9 months, 10-12 months, 1-3 years, 4-6 years, 6-11 years old, 12-14 years old) by determining the child’s body weight, height, weight and size of the thymus, and the proportion of the body weight of the thymus, the normal structure of the thymus was determined. 59% of the respondents were boys and 41% were girls. The morphometric parameters of children’s thymus increased uniformly from 1 to 3 years of age, the intensity of growth increased at 4-5 years of age and 6-11 years of age, and the intensity of growth decreased slightly at 12-14 years of age. Conclusion: It has been observed that the development of the thymus of Mongolian children is interrelated with the physical development of children, and with the increase in body weight, the length of the thymus increases rapidly, while the width and thickness of the thymus increase relatively little.
