Introduction: Women attending public antenatal clinics in the Northern Beaches who are diagnosed with GDM during pregnancy, are managed at the Manly Hospital GDM Clinic.
Objective: To compare the demographics and neonatal outcomes of women with GDM seen at Manly Hospital in 2012 to 2015.
Results: Between January 2012 and December 2012, 109 women were seen with GDM at Manly Hospital. Between January 2015 and December 2015, the number of women seen with GDM increased to 160. The mean±SD maternal age of women attending the Clinic in 2012 was 34.9±4.7 years, which was similar to 34.7±7.0 years in 2015 (p=0.73). In 2012, 63% of women attending the Clinic were non-Australian born which was similar to 62% in 2015 (p=0.90). There was no difference in weight at booking in (p=0.63) or insulin use (p=0.69) between 2012 and 2015. Metformin therapy was not used for the management of GDM in 2012. In 2015, six women were managed with metformin therapy for GDM, which was ceased at 35 weeks gestation.
There was no difference in neonatal birthweight (p=0.79), the incidence of neonatal macrosomia (p=1.00) or the incidence of shoulder dystocia (p=1.0) between 2012 and 2015. Hypoglycaemia occurred in more neonates in 2012 (27%) compared to 2015 (5%), p<0.001.
Conclusion: The age, weight and country of birth of women attending the GDM Clinic at Manly Hospital did not change significantly between 2012 and 2015. Metformin was used in the management of GDM in 2015, but not in 2012. The proportion of women managed with insulin for GDM did not change between 2012 and 2015. Neonatal birthweight, macrosomia and shoulder dystocia did not change between 2012 and 2015; however the incidence of neonatal hypoglycaemia decreased.
