Prevalence of gestational diabetes mellitus and pregnancy outcomes in Asian women with polycystic ovary syndrome.

The aim of this study was to determine the prevalence of gestational diabetes mellitus (GDM) and the pregnancy outcomes in Asian women with polycystic ovary syndrome (PCOS). The retrospective cohort study was performed to compare pregnancy outcomes of 47 pregnancies in 41 PCOS women with 264 pregnancies in 222 women with normal menstruation. Logistic regression was used to assess the risk of PCOS on GDM, hypertensive disorder in pregnancy (HDP) and premature delivery. The mean age of both groups was 31 years. The mean body mass index (BMI) and proportion of BMI of > 25 kg/m2 were significantly higher in the PCOS than in the control group. There was no difference in the prevalence of GDM between the PCOS women and the high-risk group of the controls. The prevalence of HDP and premature delivery was significantly greater in PCOS women (21.3 and 13.3%) than in the controls (6.4 and 5.4%), respectively. PCOS was demonstrated as a risk factor for GDM and HDP with borderline statistical significance, but not for premature birth. The Cesarean section rate was higher in the PCOS than in the control group. In conclusion, the prevalence of GDM in Asian women with PCOS is high and comparable to those of a high-risk group.
