Twin pregnancy outcomes for women with gestational diabetes mellitus compared with glucose tolerant women.
OBJECTIVE
To examine pregnancy outcomes for women with gestational diabetes mellitus (GDM) and a twin pregnancy compared with glucose tolerant women with a twin pregnancy.


METHODS
Comparison of selected pregnancy outcomes.


METHODS
Wollongong, New South Wales, Australia.


METHODS
Women with GDM seen over a 10-year period by an endocrinologist, and women from a selected year of an obstetric database including Wollongong and Shellharbour Hospitals.


METHODS
Examination of pregnancy outcome data from the two sources.


METHODS
Fetal birthweights and method of delivery.


RESULTS
There were 28 GDM women with a twin pregnancy from 1229 consecutive referrals (2.3%) of women with GDM for medical management. For comparison there were 29 glucose tolerant women with twin pregnancies evaluable who had delivered over a 1-year period. For the women with GDM and a twin pregnancy there were no significant differences in demographics or outcomes except for a higher rate of elective Caesarean section.


CONCLUSIONS
The higher rate of Caesarean section appeared to be related to the combination of a twin pregnancy and GDM rather than the twin pregnancy or the GDM independently.
