BODY COMPONENT COMPOSITION AND STRESS-INDUCED FEATURES OF LEPTIN SECRETION IN FEMALES WITH VARIOUS BODY MASS INDEX
Aim. The article aims to study the dynamics of the adipose tissue hormone leptin in healthy females with different body component composition and body mass index to assess their energy status under stress. Materials and methods. Based on anthropometry and bioimpedancemetry, three groups of girls were formed: the first group included girls with a BMI of less than 18.5 kg/m2, body mass deficiency (BMD), the second – from 18.5 to 24.9 kg/m2, normal body mass (NBM), the third – with a BMI of more than 24.9 kg/m2, which corresponds to overweight (OvBM). The body component composition was determined by bioimpedancemetry. Plasma leptin concentration was evaluated by enzyme-linked immunosorbent assay both in normal conditions and during emotional stress. Results. In the selected subgroups, a significant difference in the body component composition was found with an increase in the series of BMD → NBM → OvBM. When assessing the level of metabolic processes by the magnitude of the phase angle, it was found that 3.41% of females with BMD showed signs of increased protein catabolism. The stress-induced dynamics of the hormone leptin was evaluated. In normal conditions, the concentration of leptin in blood plasma positively correlated with BMI and depended on the component composition of the body. Conclusion. In persons with BMD, the adipose tissue hormone leptin had a negative dynamics under stress conditions, which was an adequate adaptive physiological response to stress. Females with BMD had a significantly high positive dynamics of leptin, while girls with OvBM did not have significant changes in its concentrations, which can be explained by the development of leptin resistance.
