摘要
目的 全面了解河北省居民户食用碘盐情况,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）〉,2007-2009年在河北省以县（市、区）为单位,按照系统抽样原则抽取乡（镇）和行政村,在行政村按照单纯随机抽样法抽取居民户,采集家中食用盐,用直接滴定法测定其含碘量.结果 2007、2008和2009年分别检测盐样48 675、48 448和48 756份,按人口数加权后合格碘盐食用率分别为91.16%、91.96%和96.17%.2007年和2008年合格碘盐食用率＜90%的县（市、区）分别有41和30个,占24.6%（41/167）和18.0%（30/167）,2009年100.0%（167/167）的县（市、区）合格碘盐食用率≥90%.3年间各县（市、区）合格碘盐食用率频数分布比较,差异有统计学意义（H=10.778,P＜0.01）,其中2007年和2008年比较,差异无统计学意义（P＞0.05）,2007、2008年与2009年比较,差异均有统计学意义（P均＜0.05）.结论 2007-2009年河北省居民户合格碘盐食用率逐步上升,到2009年所有县（市、区）的合格碘盐食用率≥90%,达到了〈实现县级消除碘缺乏病目标考核评估方案〉中的要求.
Objective To find out the situation of household consumption of iodized salt in Hebei province so as to provide scientific basis for prevention and control of iodine deficiency disorders（IDD）. Methods According to the ＂national iodine deficiency disorders surveillance program （Trial）＂, the county （city, district） was taken as a unit, township （town） and administrative villages were selected in accordance with the principle of systematic sampling, then households were chosen by random sampling to collect their edible salt in Hebei province from 2007 to 2009. Salt iodine content was detected by direct titration method. Results A total of 48 675, 48 448 and 48 756 salt samples were collected from 2007 to 2009, respectively. The consumption rate of qualified iodized salt from 2007 to 2009 was 91.16%, 91.96% and 96.17%, respectively. There were 24.6%（41/167）and 18.0%（30/167）counties with consumption rate of qualified iodized salt under 90% in 2007 and 2008, respectively. The percentage of counties with consumption rate of qualified iodized salt above 90% was 100.0%（167/167） in 2009. In general there was a significant differences in frequency distribution of consumption rates of qualified iodized salt among the three years（H = 10.778, P 〈 0.01 ）, and the difference was found significant between 2007 and 2009 as well as between 2008 and 2009（all P 〈 0.05）, but was not significant between 2007 and 2008（P 〉 0.05）. Conclusions The consumption rate of qualified iodized salt at household level increases annually from 2007 to 2009. By 2009,the consumption rate of qualified iodized salt in each county is more than 90%, which has reached the national standard stipulated in ＂the evaluation programs for fulfilling the goal of eliminating IDD at county level＂.
