TI - Goiter Survey and Urinary Iodine Concentration in Schoolchildren Aged 8 to 10 Year of Hamadan Province in 1996 PT - JOURNAL ARTICLE TA - umsha JN - umsha VO - 8 VI - 3 IP - 3 4099 - http://sjh.umsha.ac.ir/article-1-856-en.html 4100 - http://sjh.umsha.ac.ir/article-1-856-en. SO - umsha 3 ABĀ  - 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 a priority health problem in the country , and a national IDD council was formed in 1989, under the supervision of the ministry of health and medical education. One of the main strategies of national council for IDD control was to provide at least 150 mg 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 Hamadan province. 1300 schoolchildren , aged 8 to 10 year, including 50% girls and 50% boy, were selected through random sampling. Grading of goiter was performed according to WHO’s classification. Serum T3, T4 and TSH were measured by RIA and urinary iodine by digestion method. The mean of serum T3, T4 and TSH were: 9.6±2.0 mg/dl , 165±3 ng/dl and 1.7±0.7 mIu/ml respectively. There were no differences between males and females and schoolchildren of rural or urban areas. Six person had serum T4 more than 12.5 mg/dl. The mean of urinary iodine was 36 mg/dl in entire population, 89% had urinary iodine more than 10 mg/dl. Only 4% had urinary iodine less than 5 mg/dl. Total prevalence of goiter was 86% (91% in girls and 78% in boys). Based on the available data , seven years after generalized use of iodized salt and 2 years after that more than 50% of population used iodized salt , urinary iodine excretion is in acceptable limit. However goiter is still hyperendemic in Hamadan province. CP - IRAN IN - LG - eng PB - umsha PG - 0 PT - Original YR - 2001
