目的:了解和掌握大通县碘营养状况,发现碘缺乏病防治工作中存在的问题,评估其是否已达到国家碘缺乏病(IDD)消除标准,为今后制定防治措施提供科学依据。方法:采用随机抽样方法抽取大通县良教乡和斜沟乡进行碘营养状况调查;尿碘测定采用尿碘快速定量检测试剂盒测定;盐碘采用GB/T 13025.7-1999直接滴定法。结果:良教乡和斜沟乡(8～10)岁儿童甲状腺肿大率(触诊法)为3.45%;儿童尿碘中位数分别为222.70μg/L、237.85μg/L;居民用户碘盐合格率分别为87.10%、88.71%。结论:大通县总体碘营养状况不断得到改善;(8～10)岁儿童尿碘水平及甲状腺肿大率均达到了国家IDD消除标准,碘盐合格率基本达到国家IDD消除标准;碘缺乏病防治工作有所改善,为达到国家IDD消除标准仍需进一步加强宣传力度。
OBJECTIVE: To understand and master the iodine nutrition status in Datong County and to find out the problems existing in the prevention and control of iodine deficiency disorders. To assess whether it has reached the national IDD elimination criteria and to provide a scientific basis for future prevention and treatment measures. Methods: The iodine nutrition status of Liangjiao and Xiegou townships in Datong County was investigated by random sampling method. Urinary iodine was determined by rapid quantitative detection kit of urinary iodine. Salt iodine was determined by direct titration method of GB / T 13025.7-1999. Results: Goiter rate (palpation) was 3.45% in Liangjiao Township and Xiegou Township (8-10 years old), and urinary iodine was 222.70μg / L and 237.85μg / L in children respectively. Salt pass rates were 87.10%, 88.71%. Conclusion: The overall iodine nutrition status of Datong County has been continuously improved. Urinary iodine level and goiter rate in children aged 8-10 years have reached the national IDD elimination standard, and the pass rate of iodized salt has basically reached the national IDD elimination standard. The prevention and treatment of iodine deficiency deficiency Work has been improved, in order to reach the national IDD elimination standards still need to further strengthen publicity efforts.
