[Incidence of goiter in children of the Tarnobrzeg district and environmental factors].

A group of 1897 school children from Tarnobrzeg district were examined out of this number 1241 (65.4%) children displayed goiter. Goiter incidence was also established depending upon age and sex. The analysis also included goiter incidence in relation to its size according to the WHO classification. In certain patients, newborns and their mothers, determinations of iodine excretion were made; the values were found to be within the normal. This range suggests that other etiological factors than iodine deficiency might possibly contribute to goiter development in the studied children.
