COMPONENT COMPOSITION OF THE BODY AND ITS RELATIONSHIP WITH THE MODERN EATING BEHAVIOR OF YOUNG PEOPLE
Timely diagnosis of deviations in the eating behavior of young people and changes in body composition are significant points for programs to improve the health status of boys and girls. The purpose of the study is to determine the nutritional habits of adolescents and their influence on the component composition of the body. A retrospective evaluation of the results of a questionnaire on actual nutrition and a screening examination of 58 students of Sechenov University aged 17 to 21 years was carried out. The assessment of the parameters of the component composition of the body was carried out using the analyzer of bioimpedance processes ABC-01 "Medass". Statistical data processing was carried out using the methods of parametric and nonparametric analysis. A significant part of the students (36%) had scores of restrictive eating behavior below the norm, emotional - above the norm (63.8%), as well as increased scores of external eating behavior (36%). A statistically significant strong direct correlation was obtained between the indicators of basal metabolism and musculoskeletal mass of the examined (r = 0.95, p = 0.03). Among the boys, 20.8% of the phase angle was above the norm, while 15.7% of the girls had it below the norm. When assessing body fat mass, the most common among girls was the group with a high fat content (55.9%); in 29.2% of cases among young men, a low fat content was detected. Boys and girls aged 17-21 in a large city have a change in eating behavior, which is reflected in an increase in body weight in girls and malnutrition in boys, i.e. the phase angle in 20.8% of boys exceeds normal values, and in 15.7% of girls, on the contrary, it is below the norm. BMI provides only an indirect assessment of the development of adipose tissue, therefore, for more reliable results, it is necessary to estimate the percentage of adipose tissue using BIA.
