Assessment of urine iodine in school children from urban and rural areas of Tehran in 2001.
Pak J Med Sci Jan ;20(2):131-6.

Introduction: Following the national survey for Iodine Deficiency Disorder (IDD) in 1989 which manifested endemic goiter in Iran, the iodination program was implemented. By 1998, Iran has managed to become an IDD-free country. This study is a part of continuous assessment to monitor the effectiveness of this program. Methods: The prevalence of iodine deficiency was studied by assessment of urine iodine concentration among a random sample of schoolchildren, in the South Tehran. The extent of salt iodination in the public was assessed meanwhile. Results: Most cases (52.19%) showed a urine iodine concentration between 10-30 µg/dl. As well, 5.85% of pupils had mild iodine deficiency according to world standards, 1.45% of pupils showed moderate and none had severe IDD. Examination of consumed salt in public areas showed 98.8% iodination. Conclusion: Total mean iodine excretion was obviously above the state survey in 1996. The risk of exceeding the allowed limits (<30 µg/dl) should be attentively studied.
