OSTEODENSITOMETRY PARAMETERS ADOLESCENTSAGED 12-18 YEARS IN AKTOBE

Abstract

Introduction. Conducted in the last decade, epidemiological studies have convincingly
demonstrated that the OP problem originates in childhood in adult patients. It is known, that the
formation of bones occurs in the early years of life, their mass (mineral density) reaches a maximum
by 18-20 years. Violation of the processes of bone formation in a child under the influence of socalled pre-morbid conditions or chronic diseases leads to the formation of a decrease in bone
strength already in childhood and, as a consequence, an increased risk of osteoporosis and bone
fractures in the future. Lack of accumulation of peak bone mass is a major risk factor for OP, as
formed by the consideration of age bone substance consumed afterwards. In this regard, the study of
the features of the formation of bone mass in children is an actual direction of modern medicine.
Purpose of research: Determine the influence of sex, age, body weight and growth on the
osteodensitometric parameters of the heel bone of healthy children aged 12-18 years.
Materials and Methods: The design of the study is a cross-sectional one-stage, descriptive
study.In order to study the state of bone mineral density (BMD) in healthy children osteodensitometry
of the heel bone was performed on the ultrasonic densitometer (SONOST-3000, South Korea). The
study examined 396 adolescent students. There are given anthropometric and densitometric
indicators of study participants. In the course of the study, densitometric examination of bone tissue
was performed in 396 teenage schoolchildren. There are given anthropometric and densitometric
indicators of the study participants. All statistical analysis was carried out using the software Statistica
10. Student's criterion was used for an independent sample of qualitative parameters and for
determining statistical differences in individual sex groups. With the help of a simple linear regression
analysis was determined the relationship in individual sex groups. A p value of ˂0.05 was taken as
significant.
Conclusions: According to anthropometric indicators boys were differ, girls’ densitometric
indicators (percentages of bone mineral density (Z-score %) and slowing broadband ultrasonic waves
(BUA)) are characterized by relatively high.
BUA indicators in age dynamics from 12 to 18 years stable increased in boys, while in girls
decreased. In the course of regression analysis by gender, the relationship between body mass index
and BUA (R2=0,3; R2=0,26; р<0,005). In accordance with the obtained results, in the early stages of
puberty, it requires further in-depth study, but the girls are confirmed with a low BMD.
