Background: The number of publication on head size of newborns of hypothyroid mothers is scant.
Aim: To study concomitantly head circumference, birth length and weight in such neonates.
Method: Data was retrieved from computerized medical records of our hospital.
Results: One hundred and thirty nine neonates (82 males and 57 females) from a total of 18,538 deliveries at the Rabin Medical Center during the years 19871993 were studied. The female neonates had a significantly smaller head circumference than the males 34.3±1.4 vs 33.8±1.5 cm (P0.047) and that neonates of both genders had a tendency to a smaller head circumference than the control population. The birth length and weight were similar to the controls.
Conclusion: The head circumstance (brain size) in neonates of hypothyroid mother tends to be smaller than of healthy mothers. Whether this is due to inadequate treatment remains to be established.
