Abstract
Since 2000 urinary iodine concentration (UIC) has been measured in East Azerbaijan. For the first time in 2003 the median of UIC was decreased drastically. For the evaluation of Iodine deficiency disorders (IDD) program two studies were designed. In the first study UIC in children, aged 8-10 and in the second study iodine content of salt samples in factories was measured. Median UIC in 2003 was 68μg/l and in 2004 was 65μg/l. As well the mean of iodine content in salt samples was 12.37 ppm. Median UIC in 2005 was increased to 107 μg/l and after 1 year it was reached to 119 μg/l. The mean of iodine content in salt samples was elevated to 25.19 ppm & 32.36 ppm in 2005 and 2006 respectively. In 2003 and 2004 mild iodine deficiency was shown and in 2005 & 2006 it was in optimal range. There was probable correlation between urinary iodine concentration and iodine content in salt. Past experiences are made show that (IDD) could be returned easily. For sustainable and effective program we need regular monitoring activities.
