摘　　要：目的了解2008年河北省非高碘县碘盐和高碘县非碘盐的居民食用情况，为碘缺乏病防治工作提供科学依据。方法根据《全国碘缺乏病监测方案（试行）》，在河北省以县（市、区）为单位，按照系统抽样和简单随机抽样原则抽取乡（镇）和行政村，在行政村按照简单随机抽样原则抽取居民户，取家中食用盐检测盐碘。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167个非高碘县（市、区）共抽取48448份居民户食用盐，经过县级人口数加权后非碘盐率为4．73％，碘盐覆盖率为95．27％，碘盐合格率为96．13％，合格碘盐食用率为91．96％。碘盐覆盖率≥95％的县（市、区）占80．83％（135／167），碘盐合格率〉90％的县（市、区）占92盘1％（155／167），合格碘盐食用率〉90％的县（市、区）占82．04％（137／167）。在5个高碘县共抽取食用盐1466份，非碘盐1367份，非碘盐率为93．25％（1367／1466）。结论河北省非高碘地区的碘缺乏病防治工作基本达到国家要求，但部分非高碘县（市、区）碘盐覆盖率和合格碘盐食用率较低，应加大防治工作力度，而高碘地区应尽快落实停供碘盐政策。Objective To investigate the supply of iodized salt in non-excessive iodine counties and iodine-free salt in excessive iodine counties at household level in Hebei province so as to provide a basis for the prevention and control of iodine deficiency disorders （IDD）. Methods According to the national project of IDD surveillance, the county was taken as the elementary sampling unit. The towns and villages were selected by systematic and random sampling in every county and households were chosen by random sampling to collect their edible salt in Hebei province in 2008. The salt iodine content in non- and excessive iodine regions was detected by direct titrition method and semiquantitative method respectively. Results all 48 448 salt samples were collected from 167 non-excessive iodine counties. Weighed by the population of counties, the rate of non-iodized salt was 4.73%. Iodized salt accounted for 95.27%, out of which, 96.13% were qualified and the consuming rate of qualified iodized salt was 91.96%. Eighty point eighty three percent（135/167） of the counties covered by iodized salt above 95%, 92.81%（155/167） passing rate of iodized salt above 90% and 82.04（137/167） consuming rate of qualified iodized salt. All 1466 salt samples were collected in 5 counties with excessive water iodine content and the coverage rate of iodine-free salt was 93.25% （1367/1466）. Conclusions In a nutshell, the national targets for preliminary elimination of IDD have been achieved in regions of non-excessive iodine of Hebci province. Nevertheless, the coverage rate of iodized salt and qualified iodize salt rate in some counties are still below the national standard. Therefore the prevention and control of IDD need to be strengthened. The supply of iodized salt in excessive iodine regions should be timely stopped.
