摘要
目的了解桐乡市通过消除碘缺乏病中期评估后,碘缺乏病的流行动态,探讨可持续消除碘缺乏病工作机制。方法对居民户进行碘盐随机和重点抽样监测,共抽取9个镇(街道),36个行政村,588户居民食用盐,同时采集育龄妇女尿样147份;抽取5所小学,对8~10岁在校学生进行甲状腺肿大率检查(触诊法、B超法),并从B超学生中,采集尿样150份(男女性各半)进行尿碘检测。结果居民合格碘盐食用率分别为94.79%、92.67%。8~10岁儿童甲状腺肿大率触诊法为3.27%,B超法为8.91%;育龄妇女和儿童尿碘中位数分别为198.32μg/L,171.10μg/L。结论桐乡市目前人群碘营养状况良好,已为足量碘摄入状态且处在安全碘摄入量范围。采取全民食盐加碘对控制碘缺乏危害切实可行,安全可靠。
