Maternal outcomes
There was no significant difference in poly/oligohydramnios between
women who had GDM and those who were normoglycaemic. Participants within
the GDM group had higher risk of hypertensive disorders in pregnancy
compared to the normoglycaemic participants (8.0% Vs 3.8%; p-value
<0.01). Similarly, a higher proportion of women with GDM
underwent Caesarean delivery as compared to normoglycaemic participants
(39.7% Vs 28.7%; p-value <0.01). Approximately three
quarters (73.2%) of Caesarean deliveries were coded as ‘Emergency’
rather than ‘Elective’, with similar distribution among the GDM and
normoglycaemic groups. There were no significant differences in other
maternal delivery complications between the groups (Table 2). There was
one maternal death, in the GDM group, due to intrapartum haemorrhage
from a ruptured uterus secondary to obstructed labour.
