1414 school children (789 boys and 625 girls) residing in east-Tehran, were evaluated for the evidence of goiter. 88% of girls and 71.5% of boys had goiter. In 30% of girls and 17.5% of boys goiter was clearly visible (grade 2 and over). FT4I, FT3I, TSH, and thyroglobulin concentrations were not significantly different in groups with or without goiter. The concentration of iodide in urine was 21.05 ± 11.90 µg per gram of creatinine and in 67 of 69 student tested it was below 50. This study shows that Tehran is a hyperendemic goiter region. However, no thyroid dysfunction could be found in effected individuals.
