摘　　要：目的了解2011年江苏省高碘县与非高碘县居民食用盐碘情况，为碘缺乏病防治工作提供科学依据。方法2011年，根据《全国碘缺乏病监测方案（试行）》要求，在江苏省以县（市、区）为单位，按照系统抽样和单纯随机抽样原则抽取乡（镇）和行政村，在行政村按照单纯随机抽样原则抽取居民户，采集家中食用盐样，进行盐碘检测。用直接滴定法测定非高碘县居民户盐碘，半定量检测高碘县居民户盐碘。结果在106个非高碘县（市、区）共监测30840份居民家中食用盐，合格碘盐30303份，非碘盐199份，经过县级人口加权后，非碘盐率为O．71％，碘盐覆盖率为99．29％，碘盐合格率为98．93％，合格碘盐食用率为98．23％。在5个高碘县共抽取食用盐1296份，无碘食盐1283份，无碘食盐率为98．99％。结论江苏省非高碘地区和高碘地区的碘缺乏病防治工作均达到国家要求，但仍应加强对高碘地区非碘盐和非高碘地区碘盐的管理工作。Objective To investigate the supply of iodized salt in n0n-excessive iodine counties and iodine-free salt in excessive iodine counties at household level in Jiangsu Province so as to provide a basis for the prevention and control of iodine deficiency disorders（IDD）. Methods According to the ＂National Iodine Deficiency Disorders Monitoring Program（Trial）＂, county（city, district） was taken as a elementary sampling unit in Jiangsu Province. Townships （towns） and administrative villages were selected by systematic sampling and random sampling in every county and households were chosen by random sampling to collect their edible salt samples. The salt iodine content in non- and excessive iodine regions was detected by direct titration method and semi-quantitative method, respectively. Results All 30 840 salt samples were .collected from 106 non-excessive iodine counties, and qualified iodized salt was 30 303 copies, iodine-free salt 199 copies. Weighted by the population of counties, the rate of iodine-free salt was 0.71%, the coverage rate of iodized salt accounted for 99.29%, out of which, 98.93% was qualified and the consuming rate of qualified iodized salt was 98.23%. All 1296 salt samples were collected in 5 counties with excessive water iodine content and the coverage rate of iodine-free salt was 98.99% （1283/1296）. Conclusions The national targets for preliminary elimination of IDD have been achieved in regions of non- excessive and excessive iodine of Jiangsu Province. But it still should be strengthen the management work of iodine- free salt in excessive iodine counties and iodine saft in non-excessive iodine counties.
