Characterization of the anatomical variability of the body composition of adolescents in normal and in the autonomic dysfunction syndrome

AIM: To study the anatomical variability of the component composition of the body in adolescents in normal conditions, and in autonomic dysfunction syndrome (ADS), using anthropometry and bio-impedance analysis. MATERIALS AND METHODS: The study involved healthy adolescents and adolescents with ADS of the vagotonic, mixed and sympathicotonic types. The values of basic anthropometric (body length and weight, waist, and hips) and bio-impedance metric values (absolute and relative values of fatty, lean, musculoskeletal, and active cell masses) were obtained. The Quetelet index (BMI), and waist-hip index were calculated. Statistical analysis of the data obtained was performed. RESULTS: Low values of anthropometric indicators, absolute values of fat, lean, musculoskeletal masses, and high values of active cell mass were observed in the group of adolescents with the vagotonic type of ADS compared to other groups of examined adolescents. High values of anthropometric indicators, absolute values of fat, lean, musculoskeletal masses, and low values of active cell mass were obtained in the group of adolescents with a sympathicotonic type of ADS. The values of the studied parameters in groups of healthy adolescents and adolescents with mixed-type ADS occupied an intermediate position compared to the groups with vagotonic and sympathicotonic types. CONCLUSIONS: Statistically significant differences in the values of the absolute and relative indicators characterizing the component composition of the body, were revealed in practically healthy adolescents and adolescents with various types of autonomic dysfunction syndrome.
