目的了解和掌握碘缺乏病(IDD)在云南省龙陵县的防治状况及影响因素,为进一步防治碘缺乏病策略的制订提供科学依据。方法按《全国碘缺乏病防治监测方案》和国家《实现消除IDD阶段目标评估方案》要求,对龙陵县8~10岁儿童的甲状腺肿大率、尿碘中位数、碘盐合格率、碘盐覆盖率、五年级学生和农村家庭主妇碘缺乏病知识知晓率等进行监测评估。结果8~10岁甲状腺肿大率由2006年的3.75%下降到2008年的2.50%,平均尿碘中位数在297.8μg/L,并连续维持在较理想的水平,尿碘含量小于50μg/L以下者占3.3%,碘盐合格率、覆盖率分别达到97.63%,99.6%,五年级学生组和农村家庭主妇组碘缺乏病防治知识知晓率分别为90.1%和91.6%。结论龙陵县已达到了国家消除碘缺乏病标准。
