How HbA1c measurement helps in women with GDM

WOMEN with gestational diabetes mellitus (GDM) who have elevated HbA1c levels have an increased risk of fetal macrosomia and neonatal hypoglycaemia, Australian researchers have found.

This compares with the 75g oral glucose tolerance test which predicts only neonatal hypoglycaemia, says the team from the Ingham Institute and Liverpool Hospital, Sydney.

In a retrospective study of 1200 women with GDM the researchers found those with HbA1c at or over 5.4% (>35mmol/mol) measured at diagnosis had a greater risk of having a large-for-gestational age baby compared with those
