摘要

的目标。本文旨在研究不同身体成分和体重指数的健康女性脂肪组织激素瘦素的动态变化,以评估其在应激下的能量状态。材料和方法。基于人体测量和生物阻抗测量,形成了三组女孩:第一组包括BMI小于18.5 kg/m2的女孩,体重不足(BMD),第二组-从18.5到24.9 kg/m2,体重正常(NBM),第三组- BMI大于24.9 kg/m2,相当于超重(OvBM)。采用生物阻抗法测定体成分。用酶联免疫吸附法测定正常状态和情绪应激状态下的血清瘦素浓度。结果。在所选择的亚组中,随着BMD→NBM→OvBM系列的增加,发现身体成分组成存在显著差异。通过相位角的大小来评估代谢过程的水平,发现3.41%的BMD女性表现出蛋白质分解代谢增加的迹象。对应激诱导的瘦素激素动态进行了评价。正常情况下,血浆瘦素浓度与BMI呈正相关,且取决于机体成分组成。结论。在骨密度低的人群中,脂肪组织激素瘦素在应激条件下呈负动态,这是对应激的适当适应性生理反应。BMD女性瘦素阳性动态显著增高,而OvBM女孩瘦素浓度变化不明显,这可以解释为瘦素抵抗的发生。

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.
