目的了解慈溪市学龄儿童碘营养状况,以便提出相应的防治措施。方法2004-2008年共采集慈溪市8~10岁儿童尿样468份,尿碘测定应用砷铈催化分光光度法。结果468份尿样的尿碘中位数为313.40μg/L,未检出尿碘<50μg/L的样本,尿碘<100μg/L的样本占0.21%,尿碘≥100μg/L的标本除2004年占当年检测数的98.33%外,其他年度均为100.00%。结论2004-2008年慈溪市学龄儿童尿碘中位数偏高。建议碘盐的质量浓度应做适当调整,以真正达到科学补碘的目的。
Objective To understand the iodine nutrition status of school-age children in Cixi City in order to put forward the corresponding prevention and treatment measures. Methods A total of 468 urine samples were collected from 8 to 10 years old children in Cixi from 2004 to 2008. Urinary iodine was measured by arsenic and cerium catalytic spectrophotometry. Results The median of urinary iodine in 468 urine samples was 313.40μg / L, no urinary iodine <50μg / L, urinary iodine <100μg / L accounted for 0.21%, urine iodine ≥ 100μg / L In 2004, it accounted for 98.33% of the total number of test in the same year, while the other annual figures were 100.00%. Conclusion The median urinary iodine of school-age children in Cixi from 2004 to 2008 was high. It is suggested that the quality of iodized salt should be properly adjusted to achieve the purpose of scientific iodine.
