Abstract:
Objective To analyze the occurrence of insulin resistance ( IR ) and abnormal glucose metabolism in adolescent polycystic ovary syndrome (PCOS). Methods PCOS group included 141 patients aged 15-19 years old, who were diagnosed as PCOS according to criteria by reference to the European Society of Reproduction and Embryology/American Society for Reproductive Medicine proposed in 2003, at Rotterdam; and 266 age-matched female students,with regular menstrual cycles and no family history of diabetes, were enrolled in control group. Fasting insulin(FINS),fasting plasma glucose(FPC) ,and homeostasis model assessment for insulin resistance ( HOMA-IR) were measured in control group. 73% percentile value of control group was set as physical upper limits of FINS and HOMA-IR. PCOS patients were divided into obese ( OB-PCOS) and non-obese (NOB-PCOS) groups, and oral glucose tolerance test(OGTT) were performed. Results According to 75% percentile value of control group,the physical upper limits of FINS and HOMA-IR were 13.13 mIU/ L and 2.69, respectively. FINS and HOMA-IR values in PCOS group were higher than those in control group [ (17.68±16. 13 vs 10.40±5. 33)mIU/L,2. 64±2.01 vs 2. 01 ±1. 61,both P<0.01]. FINS and HOMA-IR values in OB-PCOS group were higher than those in the NOB-PCOS group [ (22.04± 18.01 vs 13.06± 12. 60) mIU/L,4. 62±3. 87 vs 2.38±2.26,both P<0.01]. In PCOS group,FINS of 75 cases(53.19% )and HOMA-IR of 67 patients(47.52% ) exceeded the physical upper limits. In 79 OB-PCOS patients, FINS of 56 cases (70. 89% ) and HOMA-IR of 52 patients (65.82% ) exceeded the physical upper limits while in 62 NOB-PCOS patients there were 19(30.65% ) and 15 (24. 19% )patients. In PCOS group,2(1.42% ) patients were diagnosed diabetes mellitus,and both FINS and HOMA-IR of these two cases increased. Meanwhile, 12 cases(8.51% ) were impaired glucose tolerance(ICT) ,of whom 11 patients FINS and HOMA-IR increased. Conclusion Pathological IR is prevalent in adolescent PCOS, more severe and popular in obese-PCOS, a part of them with abnormal glucose metabolism.
