目的了解三明市“十二五”期间碘缺乏病防治动态,为制订“十三五”防治规划提供依据。方法用合格碘盐食用率、甲状腺肿大率和尿碘浓度等指标,分析三明市居民碘缺乏病病情变化。结果 2011—2015年居民碘盐覆盖率、碘盐合格率、合格碘盐食用率均保持在95%以上;8~10岁儿童甲状腺肿大率<5%,尿碘含量低于100μg/L的均<50%,低于50μg/L的均<20%。随着盐碘浓度调整,8~10岁儿童尿碘中位数由237.1μg/L降至177.5μg/L,碘营养由超过适宜量降至适宜水平;哺乳期妇女尿碘中位数由191.4μg/L降至119.2μg/L,碘营养维持在适宜状态;孕妇尿碘中位数由171.3μg/L降至122.4μg/L,碘营养由适宜降至不足。结论三明市碘缺乏病防治维持在消除碘缺乏病状态,居民碘营养水平总体适宜,盐碘浓度下调幅度是可接受、适宜的,但孕妇存在碘缺乏风险。
Objective To understand the prevention and control of iodine deficiency disorders in Sanming City during the “Twelfth Five-Year Plan” and provide the basis for the formulation of “Thirteen-Five” prevention and control plans. Methods The prevalence of iodine deficiency disorders in Sanming City was analyzed with the index of iodized salt consumption, goiter rate and urinary iodine concentration. Results The coverage of iodized salt, the qualified rate of iodized salt and the rate of qualified iodized salt were all above 95% in 2011-2015. The goiter rate was less than 5% in children aged 8-10 years and the urinary iodine content was less than 100μg / L All <50%, <20% below 50 μg / L. With the adjustment of salt concentration, the median urinary iodine of children aged 8 to 10 decreased from 237.1 μg / L to 177.5 μg / L, and the iodine nutrition dropped from the appropriate level to the appropriate level. The median urinary iodine of lactating women increased from 191.4 μg / L to 119.2 μg / L, the iodine nutrition maintained in a suitable state; the median urinary iodine of pregnant women dropped from 171.3 μg / L to 122.4 μg / L, and the iodine nutrition was suitably reduced to inadequate. Conclusion The prevention and treatment of Iodine Deficiency Disorders in Sanming City maintains the state of iodine deficiency deficiency elimination. The iodine nutrition level of residents is generally suitable. The down-regulation of salt-iodine concentration is acceptable and appropriate, but pregnant women are at risk of iodine deficiency.
