目的了解自2011年开始实施新碘盐标准后三明市居民碘营养状况,为有效落实科学补碘防控策略提供依据。方法按《碘盐浓度调整后福建省居民碘营养状况调查技术方案》要求对城区和农村2个调查点的8~10岁儿童、成人、孕妇和哺乳期妇女进行尿碘水平和碘缺乏病病情调查。结果居民饮用水水碘值均<1!g/L;三元区、明溪县2个调查点的碘盐覆盖率分别为96.7%和100.0%,合格碘盐食用率均为96.7%;日人均食盐摄入量(7.65“4.11)g,中位数7.09g;儿童、成人、孕妇和哺乳期妇女尿碘中位数分别为167.8、171.7、155.2和101.9!g/L,哺乳期妇女尿碘中位数明显较低。结论三明市为外环境缺碘地区。自实施新碘盐标准后居民的碘营养状况处于适宜水平,但农村哺乳期妇女尿碘营养轻度缺乏。今后应加强对孕妇和哺乳期妇女(特别是农村)碘营养水平监测力度。
