Abstract:
Objective To investigate characteristics of glucose metabolism of non-obese and obese women with polycystie ovary syndrome(PCOS).Methods From March 2008 to July 2011,118 PCOS patients were enrolled in this study and were divided into 53 cases (body mass index(BMI) ≥25 kg/m2) in obese group and 65 cases (BMI ＜ 25 kg/m2) in non-obese group.Participants' clinical data,glucose tolerance and insulin release test results were retrospectively reviewed.The prevalence of type 2 diabetes mellitus (T2DM),results of oral glucose tolerance test,impaired fasting glucose (IFG),impaired glucose tolerance (IGT) were compared between the two groups.Results (1) Blood glucose levels:at the time points of 30,60,120 and 180 minutes,the levels of fasting glucose were (5.2 ± 1.1),(8.5 ± 2.8),(8.1 ± 2.4),(6.3 ± 2.0) and (4.8 ± 1.5)mmol/L in non-obese group and(5.4 ±0.9),(9.1 ± 1.8),(9.3 ±0.6),(7.6 ± 1.0) and (5.4 ±0.8) mmol/L in obese group.Statistical difference was observed between obese and non-obese groups at each time point (t =-6.125,-4.005,-6.074,-6.751 and-4.512 respectively,P ＜0.01).(2) The level of insulin:at the time points of 30,60 and 120 min,the level of fasting insulin were (8 ± 4),(55 ± 21),(65 ± 14) and (45 ±18)mU/L in non-obese group and (13 ± 8),(85± 30),(105± 54) and (76 ± 46)mU/L in obese group.There were significant statistical difference between the two groups at each time point (t =-17.024,-12.540,-15.791 and-16.149 respectively,P ＜ 0.01).However,at the time point of 180 minutes,the level of insulin did not exhibit significant difference between obese and non-obese groups (P ＞ 0.05).(3) The prevalence of abnormal glucose metabolism:The rates of IGT were 13.85 ％ (9/65) in non-obese group and 24.53 ％ (13/53)in obese group,which also showed remarkable difference (x2 =18.446,P ＜ 0.01).The rates of T2DM were 1.54％ (1/65) in non-obese group and 7.55％ (4/53) in obese group,which reached significant difference (x2=16.005,P ＜ 0.01).Conclusion Abnormal glucose metabolism was observed more frequently in overweight or obese PCOS women.
