Is mild gestational hyperglycaemia associated with maternal and neonatal complications? The Diagest Study

Summary Aims To evaluate the maternal and neonatal complications rates of mild gestational hyperglycaemia (MGH) compared to a control group in France. Methods A systematic screening by a 50‐g glucose challenge test was offered to all women between 24 and 28 weeks of gestation in 15 maternity units. If the 50‐g glucose challenge test was ≥ 7.2 mmol/l, a 100‐g 3‐h oral glucose tolerance test (OGTT) was performed. MGH (n = 131) was defined by one abnormal value on the 3‐h OGTT (Carpenter and Coustan criteria). The control group (n = 108) was defined by a 50‐g glucose challenge test below 7.2 mmol/l. Women with MGH received no treatment or specific advice during the pregnancy. Large for gestational age (LGA) was defined by a birth weight of at least the 90th percentile on French standard growth curves. Results Women with MGH were older than the controls (28.8 (5.8) vs. 27.0 (5.2); P
