State of hormonal balance in adolescent girls with menstrual function disorders associated with obesity

Investigation of the mechanisms promoting the development of menstrual function disorders associated with obesity in adolescent girls is one of the most important issues of modern medicine. This study included 110 patients. 79 patients aged 12–18 with menstrual disorders associated with obesity were divided into two groups: group 1: 46 patients with apparent signs of hyperandrogenism, group 2: 33 patients without clinical manifestations of hyperandrogenism. The control group included 31 girls of the same age with a regular menstrual cycle. The complex of hormone examination of adolescent girls included determination of serum content: gonadotropic hormones (luteinizing hormone (LH) and follicle-stimulating hormone (FSH), prolactin (PRL), estradiol (E2), testosterone (T), progesterone (PR), dehydroepiandrosterone sulfate; insulin (In) – radioisotope method on a gamma counter “Narcotest” (reagents “IMMUNOTECH”, Czech Republic). We identified hyperleptinemia and leptin resistance in patients with menstrual function impairment associated with obesity. In group I, the adiponectin level exceeded the values of the control group (p<0.05). The results revealed a decrease in A/L in group I – 5.4 times compared with patients in group II (p<0.05) and 4.3 times – compared with the control group (p<0.05). The results revealed a decrease in A/L among girls in the group I with MFI associated with obesity – 4.3 times - compared with girls in the control group (p<0,05).
