Thyroid function in the newborn in relation to maternal thyroid status during labour in a mild iodine deficiency endemic area in Sudan

The study suggests that, in areas with mild iodine deficiency, neonates may be at the limit of decompensation as evidenced by their enhanced TSH and Tg levels as well as increased T4 compared to their mothers. This finding must not create a false sense of well-being and points rather to the urgency of iodine supplementation of mothers even in areas with mild iodine deficiency, as in this part of Sudan. The mode of delivery, whether by spontaneous vaginal delivery or Caesarian section, did not seem to affect the thyroid function of the newborn.
