title: Goiter prevalence and urinary iodine excretion in schoolchildren of Jordan.
abstract: Iodine deficiency disorders (IDD) are considered a major health problem in the eastern Mediterranean region. In Jordan, an IDD assessment was performed in 1993 following which, a salt iodization and consumption program was implemented and a monitoring survey performed in 2000. In schoolchildren 8 to 10 years of age (2457 in 1993 and 2601 in 2000) goiter was graded according to WHO classification. Urinary iodine was measured in 10% of the children in 1993 and in all of them in 2000. Percent of iodine consumption in households was assessed by rapid kit test in 2000. Prevalence of goiter was 37.7 and 32.1 % and median urinary iodine was 40 and 154 microg/L, in 1993 and 2000, respectively. Before salt iodization, the prevalence of goiter and severity of iodine deficiency was more pronounced in rural regions and in the southern part of Jordan. In 2000, all but one governorate had a median urinary iodine (MUI) of above 100 microg/L. The percentage of urinary iodine levels < 50 microg in two governorates was > 20%. Iodine consumption rate of households was 88.3% throughout the country, but was < 70% in three governorates. It is concluded that moderate and severe IDD existed before 1993 in Jordan. Although the iodized salt program has been successful in optimizing MUI, the program for the control of IDD needs further improvement.
