To examine the relationship between fetal glycaemic control and macrosomia or neonatal hypoglycaemia, we measured umbilical cord glycosylated haemoglobin (GHb) by affinity chromatography in 44 diabetic and 40 normal pregnancies. Levels of GHb in cord blood were not significantly different between these two groups, suggesting good maternal glycaemic control was achieved in the diabetic patients. Moreover in the diabetic pregnancies, cord GHb levels did not differ in infants who were macrosomic or developed hypoglycaemia by comparison with those infants who showed neither phenomenon. We conclude that overall fetal glycaemic control in the 4-6 week period prior to delivery does not appear to influence these common neonatal complications of diabetic pregnancy.
