Diabetes, affecting about 1 in 20 pregnancies in Australia, is associated with poorer pregnancy and birth outcomes, says Australian Institute of Health and Welfare.

The report, Diabetes in pregnancy: its impact on Australian women and their babies, shows that there is an increased risk of these adverse effects among women with pre-existing Type 1 or Type 2 diabetes than for women with gestational diabetes mellitus (GDM), a form of diabetes that can arise in pregnancy.
But all forms of diabetes, including GDM, are associated with a higher risk.
‘The rate of stillbirths was higher among the babies of mothers with pre-existing diabetes, and they were also more likely to have low Apgar scores, high birthweights and need resuscitation or admission to special care facilities,’ Ms Templeton said.
Hypertension, pre-term birth and caesarean section were more common in women with pre-existing Type 1 diabetes than in those with pre-existing Type 2 diabetes. Stillbirth was more common among babies born to mothers with Type 2 diabetes than those with Type 1 diabetes.
Among Aboriginal and Torres Strait Islander mothers, pre-existing diabetes was 3 to 4 times as common as for non-Indigenous mothers. The rate for pre-existing Type 2 diabetes was 10 times that of non-Indigenous mothers, and GDM was twice as common.
