Insulin is a peptide hormone which is produced by β-cells of the pancreas. It is difficult to underestimate the effect of insulin, it has a significant impact on organs and systems. Insulin is a carbohydrate “conductor”, disorders of the regulation process of which lead to metabolic disorders and irreversible changes in the human body.Insulin resistance (IR) is a state of reduced response of tissues to the action of insulin, which leads to disorders, including the reproductive function of a woman. Long-term IR leads to the development of hyperandrogenism, as a result of which anovulatory cycles, hirsutism, skin problems, vaginal dysbiosis, and an increased rate of anxiety and depression.The objective: to determine the influence of anthropometric, anamnestic and laboratory indicators on insulin secretion before and after a load of 75 g of glucose.Materials and methods. The study included 82 women of early reproductive age. 52 women are involved in the main group, 30 women – in the control group. The patients signed an informed voluntary consent, and the main aspects of the study were explained to them. In the course of the research we developed a questionnaire and conducted a survey.Anthropometric parameters (height, body weight, waist circumference) were measured, and BMI was calculated. Laboratory indicators were studied: luteinizing hormone (LH), follicle-stimulating hormone (FSH), sex hormone binding globulin (SHBG), thyroid-stimulating hormone (TSH), prolactin, dehydroepiandrosterone-sulfate (DHEA-S), total testosterone, free testosterone index, HOMA-IR index, glucose tolerance test (GTT) + determination of insulin level, Matsuda index.Results. The conducted correlation analysis proved the relationship between the level of fasting insulin and the following indicators: WC – r = 0.321900051, BMI – r = 0.333470666, establishment of the menstrual cycle – r = -0.283517408, duration of bleeding during menstruation, TSH level – r = 0.249578215, DHEA-S – r = -0.209053013, total testosterone level – r = 0.278921593.A relationship was found between the level of insulin after a load of 75 g of glucose and the following indicators: body weight at the birth of female respondents – r = -0.238495649, gestational term of birth – r = -0.243025226, FSH level – r = 0.291379519.Conclusions. A small positive (direct) relationship was determined between the fasting insulin level and the following indicators: WC, BMI, TSH level, and total testosterone level. An increase of these indicators is associated with an increase in fasting insulin level. A slight inverse linear relationship was found between the level of fasting insulin and the duration of menstrual function, the duration of bleeding during menstruation and the DHEA-S level.A slight inverse relationship is observed between the level of insulin after load and body weight at birth, the term of birth. Lower birth weight and early gestational age are associated with increased insulin levels after load.There is a direct relationship between post-load insulin levels and FSH levels. An increased FSH concentration will lead to a rise of insulin level after load.
