Abstract:
Objective To learn the iodine nutritional status of the vulnerable population with different iodine level under the current level of iodized salt in Shandong province and to offer prevention and cure measures.Methods Five groups of vulnerable population including school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age from mountain areas ( Daiyue, Mengyin counties ) , plain ( Luxian,Gaomi counties ) and coastal (Zhaoyuan county ) of five different iodine deficient areas were investigated in 2007.The thyroids of children aged 8 - 10 were checked by palpation and B ultrasound, their edible salt iodine level was detected by direct titration. The lever of urinary iodine of vulnerable population was examined by arsenic and cerium speetrophotometry. Results The goiter rates of 8 - 10 year-old were 1.8%(9/514) and 1.2%(6/514), respectively by palpation and B-ultrasonic. The mean iodine of 501 edible salt samples was 30.95 mg/kg. The coverage rate of iodized salt was 94.6% (474/501). The rate of qualified iodized salt was 90.4% (453/501). The median of urinary iodine was 216.7 μg,/L. The urinary iodine of school children aged 8 - 10, pregnant, lactation women, infants and women of childbearing age were 234.0, 165.5, 162.4, 257.5, 233.0 μg/L, respectively. Conclusions Current iodine nutritional level is basically appropriate in all groups of vulnerable people. The current iodine content of iodized salt could meet the needs of population from different iodine deficient areas of Shandong province.
