2015年湖北省碘缺乏病病情监测结果分析

Analysis of surveillance results on iodine deficiency disorders in Hubei Province in 2015

目的了解湖北省碘缺乏病病情，为制订湖北省“十三五”碘缺乏病防治规划提供科学依据。方法2015年在湖北省103个县（市、区），每个县（市、区）抽取300户居民检测家中食盐碘含量，抽取200名8～10岁儿童检测尿碘含量和触诊甲状腺肿大情况，抽取100名孕妇检测尿碘含量。结果湖北省全省共采集30900份居民户盐样，全省碘盐覆盖率、碘盐合格率和合格碘盐食用率分别为99．61％（30780／30900）、94．33％（29036／30780）和93．97％（29036／30900）；20600份8—10岁儿童尿样碘含量中位数为252．0μg／L，甲状腺肿大率为0．39％（80／20600）；共检测10257份孕妇尿样，尿碘中位数为180．0μg/L。结论湖北省碘盐防治碘缺乏病的措施总体实施较好．居民碘营养总体状况良好；食用盐的碘含量还有下调的空间，但须配套孕妇专用食用盐．以满足特需人群对碘的不同需求。

Objective To get to know the status of iodine deficiency disorders （IDD） and provide scientific basis for the 13th Five-year Plan of control and prevention of IDD in Hubei Province. Method In 2015, 103 counties were selected to test or inspect iodine content of 300 salt samples from 300 residents, urinary iodine content and thyroid volume （palpation） of 200 children aged 8 - 10, and urinary iodine content of 100 pregnant women. Results Thirty thousand and nine hundred salt samples were collected. Coverage rate of iodized salt, qualified rate of iodine salt and qualified iodine salt edible rate were 99.61% （30 780/30 900）, 94.46% （29 074/30 780） and 94.09% （29 074/30 900）, respectively; the median iodine content of 20 600 urine samples of 8 - 10 old children was 252.0 μg/L and goiter rate was 0.39% （80/20 600）; the median iodine content of 10 257 urine samples of pregnant women was 180.0 μg/L. Conclusions As a whole, the measure of control and prevention of IDD by iodized salt is implemented well in Hubei Province. The overall iodine nutrition of residents is good. However there is space to lower the iodine concentration of iodized salt with coordinated measure of special edible salt for pregnant woman to satisfy different needs of special people.
