Iodine deficiency disorders (IDD) is a worldwide health problem. Many parts of the Islamic Republic of Iran had been known as areas of endemic goiter. IDD was accepted as a priority health problem in the country , and a national IDD council was formed in 1989, under the suprevision of the ministryʹ of health and medical education. One of the main startegies of national council f 6r IDD control was to provide at least 150 µ,g of iodine per day to the entire population through making available iodized salt. This study was performed to evaluate the national IDD council program in 1996, in rural and urban areas of Sixtan and Balochestan province. 2500 schoolchildren , aged 8 to 10 year; including 50% girls and 50% boys, were selected through random sampling . Grading of goiter was performed according to WHOʹs classification . Serum T3 , T4 and TSH were measured by RIA and uninary iodine by digestion method. The mean of serum T4,T3 and TSH were:9.0±5,µgldl, 172±60ngldl and 2.0±1.8,pIu.lml respectively. There were no differences between males and females and schoolchildren of rural and urban areas. Two person had serum T4 more than 12.5µg/dl and only five person. had TSH more than 5 plu/m1. The mean urinary iodine was 23 ,µgldl in. entire population , 90% had urinary iodine more than 10 µgIdL Only 4% had urinary iodine less than 5 µg/dl . Total prevalence of goiter was 23(24% in girls and 23% in boys). Based on the available data, seven years after distribution of iodized salt, uninary iodine of schoolchildren in Sistan and Balochestan province dose not show iodine di ficiency. However goiter is still endemic in Tehran province.
