Macrosomia index in neonates of diabetic mothers as a simple predictor of maternal glycemic control

Background: About 2–5% of the pregnancies are complicated by diabetes and is recognized to be related with poor maternal and fetal outcomes. An abnormal Macrosomia index (MI) or Macrosomia index (HC in cm/CC in cm) of ≤1 can be considered as a marker for macrosomia in infants of diabetic mothers. The main objective of this study to correlate the maternal glycemic control with neonatal macrosomia index. This is a Cross sectional observational study done among the neonates of mothers with diabetes attending a Medical College Hospital. Birth weight, head circumference and chest circumference, MI, were measured. Glycated haemoglobin (HbA1C) were measured in mother at third trimester or at early puerperium. The results showed that there is a negative correlation of MI with HbA1C. So MI can be used as a predictor of maternal glycemic status and we also recommend strict glycemic control with regular monitoring of the HbA1C levels in antenatal mother and meticulous monitoring for the complications in neonates with abnormal MI (≤1).
