Diabetes and antenatal milk expression
Diabetes is increasing globally and occurs in 8% of pregnancies. These pregnancies are considered to be at high risk of perinatal complications. Many maternity providers encourage these women to express colostrum before birth to have breast milk available should the infant need supplementary feeding to treat hypoglycaemia. Evidence for this practice was lacking.
This world first study has found that women with diabetes in a low-risk pregnancy can safely express breast milk in late pregnancy, with the study dispelling concerns that the practice could cause harm to babies.
We undertook a multi-site, two arm randomised controlled trial (RCT) of antenatal expression of colostrum in late pregnancy for women with diabetes in pregnancy to explore the safety and efficacy for mother, fetus and infant. The sites were the Mercy Hospital for Women, the Royal Women's Hospital, Monash Medical Centre, Barwon Health, the Royal Women's at Sandringham, and Frankston Hospital. We commenced recruiting women for the trial in June 2011 and finished recruiting in November 2015.
The findings pave the way for clinicians to recommend that low-risk pregnant women with diabetes in pregnancy express and store breast milk to give to their newborns in the event they develop hypoglycaemia (low blood sugar levels) – a condition that can cause serious health problems in newborns.
