1 Introduction Preterm birth, defined as delivery before 37 weeks of gestation, remains a significant challenge in obstetric care, and it is a cause of significant neonatal morbidity and mortality. Late preterm birth, classified as birth between 34+0 and 36+6 weeks, accounts for 69% of all preterm births in Australia and carries increased risks of respiratory and neurodevelopmental complications compared to term births [1].

Adverse perinatal outcomes are more common in women with T1D compared to those with T2D, likely due to longer diabetes duration and poorer glycaemic control, making rigorous glycaemic management essential. For women with T2D, effective weight management prior to pregnancy is vital, as obesity significantly increases the risk of adverse maternal and neonatal pregnancy outcomes.
