Pregnancy complicated by diabetes often results in macrosomic infants (birth weight > 4000g). They are at increased risk of shoulder dystocia, brachial plexus injury, prolonged labor and caesarean section. The fetuses are at higher risk of becoming obese and developing Type 2 diabetes. We show significant increase in fetal fat volume, percentage fetal fat and fetal length but not total fetal volume at 3337 weeks in diabetics compared to controls. In utero assessment of fetal size and fat distribution would allow clinicians to identify fetuses at risk of complicated delivery and study the metabolic changes in the infant.
