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.
