Abstract: In the 1995 Natinal Survery for Monitoring IDD Prevention Program in Iran, the levels of urine iodine in Ilam province were the highest among 26 provinces. This study was designed to evaluate the reproducibility and camparison between the rural and urban regions of Ilam in 2000. In a cross sectional study 75 and 61 households aged more than 2yr from rural and urban regions of Ilam were selected by cluster sampling (352 subjects in city, 292 in villages). Urine iodine, sodium and potassium were measured in a random sampling. The salt intake of each household member was calculated. A nonfasting blood sample was drawn to perform thyroid function test. The Food Frequency Questionnaire (FFQ) was filled out for some salted foods in each household. The mean age of study population in the urban and rural regions, were 27.3±19 and 26±19.6 (P>0.05), respectively. Urine iodine and sodium levels in city and villages were 19.1±8.6 vs. 20.6±9 μg/dl (P<0.05) 157±49 vs. 166±47 meq/L (P<0.05), respectively. Mean daily intake of iodized salt (without considering salted foods) was 9±4.3 g in city and 11.6±4.3 in villages. Mean T3 in city and villages were 141±26 vs. 129±25 ng/dl (P<0.001). There was no significant difference between other thyroid function tests in the rural and urban regions. These findings reveal decreased urinary iodine levels in Ilam province in comparison with the results of the study in 1995, however within normal limits. Mean urinary iodine in rural regions was significantly higher than that in urban regions due to higher salt intake in rural regions. There was no significant difference between rural and urban regions except for T3.
