gestation and frequency of adverse perinatal
outcomes. More recently, the International
Association of the Diabetes and Pregnancy Study
Group has further analysed the HAPO study data
and recommended revised diagnostic criteria for
GDM (International Association of Diabetes and
Pregnancy Study Groups Consensus Panel, 2010),
which is reflected in the new NICE guidance
on management of diabetes in pregnancy. If a
diagnosis of GDM is confirmed, NICE (2015)
recommends a review with the joint diabetes and
antenatal clinic within 1 week.
