Ultrasound scans around 34 weeks gestation to measure fetal kidney dimensions (transverse and anteroposterior diameters, length and circumference) and derived volume. This is a nested cohort within the full BiB cohort. Women were recruited at a routine glucose tolerance test at 26-28 weeks gestation and invited to return for a further fetal ultrasound at 34 weeks gestation.
