Thyroid dysfunction in newborns and infants living in an iodine-deficient area.
The region of Southern Poland is known as an iodine-deficient area. Iodine prophylaxis was discontinued in 1980/81. This fact was discovered as a result of the introduction of newborn mass screening for congenital hypothyroidism in 1985. In view of the large number of newly detected cases of Iodine Deficiency Disorders (IDD), we compared the neonatal populations of the Cracow and Nowy Sacz provinces. The prevalence of IDD was revealed as eight times higher in Nowy Sacz than in Cracow. The iodine urine excretion rates in those two provinces were similar. The paper discusses the cause of the discrepancy in IDD incidence. The final results show that the iodine deficiency detected in the Cracow and Nowy Sacz provinces is of moderate degree. Salt iodination in the region of southern Poland needs a new approach even before the year 2000, as planned in the WHO program.
