 Background and Objectives: Iodine deficiency disorders have been one of the main health-nutritional problems in Iran for many years. Prior to the iodine-supplementation program, Ardabil province was one of the regions with endemic goiter in Iran. The program of control and prevention of iodine deficiency has been performed here since 1989 through production, distribution and consumption of iodized salt. This study was performed in 2001 on 7-10 years-old pupils of Ardabil as a part of national monitoring survey of iodine deficiency control.

 Methods: In a cross sectional- descriptive study, 1200 students (equal number of boys and girls) were selected randomly. The prevalence of goiter was determined by clinical examination and according to WHO classification. Urinary iodine content was determined in one tenth of the cases using digestion method.

 Results: Total goiter rate was 9.3 in all the subjects (10.7% in girls and 7.9% in boys). Median urinary iodine was 18.8µg/dl. In 80.7% of the cases urinary iodine was above 10µg/dl and was less than 5µg/dl in 4.2%. Urinary iodine below 2µg/dl was not observed.

 Conclusion: The results showed that the rate of goiter among pupils has significantly decreased since 1996 and urinary iodine levels in schoolchildren of Ardabil complied with WHO index. So, Ardabil province can be considered as an “iodine deficiency free” zone.
