Fetal anterior abdominal wall thickness in diabetic pregnancy.

Objective: The purpose of this study was to investigate whether third trimester fetal anterior abdominal wall (AAW) thickness in diabetic pregnancy reflects glycaemic control and predicts macrosomia.

Study Design: Prospective cohort study in a tertiary level maternity unit. One hundred and twenty-five diabetic mothers (71 pre-gestational and 54 gestational diabetics on insulin) underwent routine serial third trimester ultrasound examination with the additional measurement of AAW thickness.
