“…Для характеристики энергетического гомеостаза в полученной выборке определялась концентрация лептина как в фоновых условиях (период повседневной учебной нагрузки), так и при эмоциональном стрессе (экзаменационная сессия). Модель экзаменационного стресса довольно часто используется для изучения влияния эмоционального напряжения на различные системы организма [12, 17,22]. Концентрация лептина в сыворотке крови в ходе ИФА на каждом этапе определялась с помощью набора реагентов DRG (США) на анализаторе CHEM-7.…”

“…Таким образом, развитие метаболических нарушений, обусловленных избыточным накоплением жировой ткани, может наступить не только при избыточном весе и ожирении, но и у лиц, имеющих нормальную массу тела, что указывает на необходимость использования показателей компонентного состава тела Для оценки уровня метаболических процессов у обследованных студенток в ходе биоимпедансометрии была определена величина фазового угла. Фазовый угол представляет собой специфичную только для биоимпедансной технологии оценки состава тела величину, связанную со скоростью метаболических процессов в организме [17]. Наибольшее значение данного показателя (7,06 ± 0,11 град.)…”

“…В этой связи произведена оценка риска развития метаболического синдрома на основании значений ИТБ и процентной доли жирового компонента. При этом высокому риску соответствовало сочетание повышенного значения ИТБ и доли жирового компонента в градации «ожирение», повышенному рискусоблюдение одного из этих условий, низкому риску -одномоментное несоблюдение обоих условий [17]. Исходя из этого, у половины обследованных студенток с различным статусом энергетического гомеостаза наблюдается риск развития метаболического синдрома (рис.…”

“…Эмоциональный стресс вызывает существенные изменения в содержании многих гормонов, особенно гормонов гипоталамогипофизарно-надпочечниковой оси [17,22]. Их воздействие делает доступными энергетические субстраты (глюкозу и жиры) для клеток организма.…”

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.

Currently, among young women, the prevailing concept of female beauty is a slender figure with a poor subcutaneous fat layer. In this connection, many young girls use various diets and visit fitness clubs in order to lose body weight. After marriage, a significant number of them apply to family planning offices due to the failure to get pregnant after a year and more of regular sex life without contraception. The purpose of the research was to show the correlation between the levels of pituitary and ovarian hormones during the menstrual cycle and body weight deficit in women planning pregnancy. The study was carried out at the City Clinical Maternity House during 2014–2019. The information was gathered by interviewing women with body weight deficit, who were planning pregnancy, and by analysis of hormone levels. We examined 327 patients. The content of follicle-stimulating hormones (FSH), luteinizing hormones (LH), prolactin, progesterone, estradiol, cortisol was studied. The subjects were divided into 4 groups depending on the body weight deficit: 1st group – a decrease in body weight of up to 5%, 2nd group – a decrease in body weight from 5 to 10%, 3rd group – from 10 to 15%, 4th group – more than 15%. The studied groups were also stratified according to the main etiological factor, namely: a) insufficient nutrition in quantitative and qualitative terms (starvation, some vitamin deficiencies, etc.); b) long-term physical exertion; c) long-term psycho-emotional stress; d) asocial lifestyle (alcoholism, substance abuse). The results of the study showed changes in the level of hormones in response to the influence of these factors. It was concluded that the most important factor that changed the level of hormones in the body was a causal relationship that caused weight loss. The most significant factors were: prolonged psycho-emotional stress and malnutrition, while prolonged physical exertion and unhealthy lifestyle were milder predisposing causes that led to changes in hormonal levels in case of underweight. To relieve psycho-emotional stress and optimize nutrition, it is necessary to manage patients together with a psychotherapist and a nutritionist.
