2011—2012年贵港市碘缺乏病监测结果

Analysis on monitoring result of iodine deficiency disorders in Guigang City from 2011 to 2012

目的了解贵港市消除碘缺乏病阶段目标后人群碘营养状况，为科学防治碘缺乏病提供科学依据。方法按《全国碘缺乏病监测方案（试行）》随机抽查居民户食盐监测；按（（2011年度广西碘缺乏病防治与监测方案》抽取县（市、区）、小学，开展学生尿碘、家庭户盐碘、甲状腺B超检查，并对抽中小学附近孕妇、哺乳妇女开展尿碘抽检，同时开展水碘抽检。结果2011、2012年贵港市居民户盐碘中位数分别为33．76、27．80mg／kg，碘盐覆盖率分别为100．00％、99．74％；8～10岁学生尿碘中位数为288ug/L，甲状腺肿大率为0．83％；孕妇、哺乳妇女尿碘中位数为139．5ug/L；水碘中位数为4．7ug／L，小于10ug／L者占78．06％。结论贵港市在居民户碘盐、学生尿碘、学生甲状腺肿大率方面巩固了消除碘缺乏病成果，但孕妇尿碘水平偏低，水碘水平偏低，表明贵港市属于低碘地区，今后仍需长期实行食盐加碘预防碘缺乏危害。

[ Objective] To learn the iodine nutrition status after achieving the stage goal of elimination of iodine deficiency disease in Guigang City, provide the scientific basis for prevention and control of iodine deficiency disorders. [ Methods] The status of edible salt in households was randomly monitored according to the National iodine deficiency disorders control program （Trial）. [ Results ] According to Guangxi iodine deficiency disease control and monitoring program in 2011, the counties/cities/districts and elementary schools were collected, to carry out the urine iodine test among students, salt iodine monitoring in households, and B ultrasound ex- amination of thyroid. The urine iodine levels of pregnant women and lactating women nearby selected primary and secondary schools were randomly tested. In 2011 and 2012, median iodine content of salt among households in Guigang City was 33.76 mg/kg and 27.80 mg/kg respectively, while the coverage of iodized salt was 100. 00% and 99. 74% respectively. The median of urinary iodine among students aged 8-10 years old was 288 i.ug/L, the rate of goiter was 0. 83%, and the median of urinary iodine among pregnant women and lactating women was 139.5 ug/L. The water iodine median was 4.7 ug/L, and 78.06% were less than 10 ug/L. [ Conclusion] On the basis of the results of eliminating iodine deficiency disease, the situations of iodized salt in households, the urinary iodine level of students, and the rate of goiter among students in Guigang City are satisfactory. However, the urinary iodine level of pregnant women and the water iodine level are low relatively, which indicates that Guigang City is low iodine area, so it is necessary to carry out the long-term salt iodization, to prevent the hazards of iodine deficiency.
