The study included 23 infertile women of reproductive age. All patients were prescribed a balanced, low-calorie diet (1200 kcal/day), exercise, and behavioral therapy. The anthropometric, metabolic and hormonal parameters were determined before and 12 months after the treatment. We measured the levels of leptin, total cholesterol, triglycerides, triglycerides, high-density and low-density lipoprotein cholesterol (HDL cholesterol and LDL cholesterol), fasting glycose. Following the measurements, the atherogenic and insulin resistance indices were calculated. In addition, the plasma concentrations of luteinizing hormone, follicle-stimulating hormone, prolactin, estrone, estradiol, testosterone, progesterone, and immunoreactive insulin were measured.</p></sec><sec><title>Results</title><p>Results. Twenty patients completed the study. A decrease in body weight (by average of 10.58 ± 5.70 kg) was found in 87 % of patients; in parallel, the body mass index decreased from 32.53 ± 1.40 to 28.55 ± 2.50 kg/m2 (p &lt; 0.001). The decrease in body weight was accompanied by a statistically significant decrease in the levels of leptin (p &lt; 0.001), estrone (p = 0.049), estradiol (p = 0.032), total cholesterol (p &lt; 0.001), triglycerides (p = 0.004), LDL cholesterol (p = 0.001), fasting glycose (p &lt; 0.001), insulin resistance index (p = 0.002), atherogenic index (p &lt; 0.001) and an increase in the level of progesterone (p = 0.030). The ovulatory menstrual cycle was restored in all women (p = 0.007); within one year, wanted pregnancy occurred in 1 woman.</p></sec><sec><title>Conclusion</title><p>Conclusion. The use of a low-calorie diet for 12 months in infertile women with grade I gluteofemoral obesity leads to normalization of metabolic parameters, weight loss and, the restoration of the ovulatory menstrual cycle in 100 % of cases.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель исследования</title><p>Цель исследования: оценить динамику антропометрических, гормональных и метаболических показателей у бесплодных женщин репродуктивного возраста с глютеофеморальным ожирением I степени при назначении сбалансированной гипокалорийной диеты.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В исследование включено 23 бесплодных женщины репродуктивного возраста. Всем пациенткам была назначена сбалансированная гипокалорийная диета (1200 ккал/сут), физические упражнения и поведенческая терапия. До начала лечения и через 12 мес проводили антропометрическое обследование, исследовали метаболические и гормональные показатели в сыворотке крови: определяли содержание лептина, общего холестерина, триглицеридов, холестерина липопротеидов высокой и низкой плотности (ХС-ЛПВП и ХС-ЛПНП), гликемии натощак, рассчитывали коэффициент атерогенности (Ка) и индекс инсулинорезистентности (НОМА-IR), измеряли концентрации лютеинизирующего гормона, фолликулостимулирующего гормона, пролактина, эстрона, эстрадиола, тестостерона, прогестерона, иммунореактивного инсулина.</p></sec><sec><title>Результаты</title><p>Результаты. Исследование завершили 20 пациенток. Снижение массы тела зарегистрировано у 87 % пациенток от 4 до 24 кг (в среднем на 10,58 ± 5,70 кг), соответственно имело место снижение индекса массы тела с 32,53 ± 1,40 до 28,55 ± 2,50 кг/м2 (р &lt; 0,001). Снижение массы тела сопровождалось статистически значимым снижением содержания лептина (р &lt; 0,001), эстрона (р = 0,049), эстрадиола (р = 0,032), общего холестерина (р &lt; 0,001), триглицеридов (р = 0,004), ХС-ЛПНП (р = 0,001), гликемии натощак (р &lt; 0,001), индекса НОМА-IR (р = 0,002), Ка (р &lt; 0,001) и повышением уровня прогестерона (p = 0,030). Овуляторный менструальный цикл восстановился у всех женщин (р = 0,007), желанная беременность в течение года наступила у 1 пациентки.</p></sec><sec><title>Заключение</title><p>Заключение. Применение гипокалорийной диеты в течение 12 мес у бесплодных женщин с глютеофеморальным ожирением I степени способствует нормализации метаболических процессов, снижению массы тела и в 100 % случаев восстановлению овуляторного менструального цикла.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ожирение</kwd><kwd>репродуктивный возраст</kwd><kwd>бесплодие</kwd><kwd>диетотерапия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>obesity</kwd><kwd>reproductive age</kwd><kwd>infertility</kwd><kwd>diet therapy</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Van Dammen L., Wekker V., de Rooij S.R. et al.
