The thyroid hormone profile was investigated in goitrous schoolchildren age
d 6-11 years living in Antalya, an area with mild/moderate iodine deficienc
y. With few exceptions, the serum levels of T-4 and TSH were in the normal
range in children with different grades of goiter. Compensatory elevated T-
3 levels were detected in 24% of the subjects. Thyroid hormones did not dif
fer significantly with respect to the urinary iodine (UI) level, No correla
tions were found between thyroid volume, UI excretion level and thyroid hor
mones. It was concluded that thyroid hormones, except compensatory T-3 elev
ation in some subjects, were not affected significantly in a mild/moderate
iodine deficient area.
