摘　　要：目的 分析北京市怀柔区居民食用碘盐情况,对今后碘缺乏病防治策略提供科学依据。方法 按照《全国碘缺乏病监测方案》的要求从2015年-2017年,在怀柔区抽取15个乡镇进行居民食盐监测,根据GB/T 13025. 7—2012直接滴定法进行碘含量测定。结果 2015年-2017年碘盐覆盖率分别为100. 00%、99. 67%、91. 09%,3年间碘盐覆盖率不全相同（χ2=51. 289,v=2）。在进行两两比较之后得,2015年与2017年碘盐覆盖率之间存在差异（P 〈0. 017）,2016年与2017年碘盐覆盖率之间存在差异（P 〈0. 017）。2015年-2017年碘盐合格率分别为97. 00%、96. 32%、94. 57%,3年间差异无统计学意义（P〉 0. 05）。结论 怀柔区各项碘盐质量指标基本处于国家控制指标内,但仍存在问题,主要原因可能是居民缺乏食用碘盐的意识或盐业体制改革后有大量无碘盐进入市场。因此需要继续加大监测、监督力度,进一步开展健康教育工作,确保人民群众食用合格碘盐。Objective To provide scientific basis for the prevention and treatment of iodine deficiency by analyzing the situation of iodized salt for residents in Huairou District. Methods According to the National IDD Surveillance Program,salt monitoring for the residents of 15 townships in Huairou District was carried out during 2015-2017. The iodine contents in the salt samples were determined according to GB/T 13025. 7-2012 with direct titration method. Results The coverage rates of iodized salt were 100. 00%,99. 67%,91. 09% during 2015-2017,and the coverage rates of iodized salt were not different( χ2= 51. 289,v = 2) in the 3 years. There was difference on the coverage rate of iodized salt between 2015 and 2017( P < 0. 017),and there was also difference between 2016 and 2017( P < 0. 017). The qualified rate of iodized salt from 2015 to 2017 was 97. 00%,96. 32% and 94. 57%,respectively,and there was no statistical significance on the difference among the 3 years( P > 0. 05).Conclusion The quality indicators of iodized salt in Huairou District basically meet the state control index,but there are still some problems. The main reasons may include that the residents lack the awareness of iodized salt consumption or that there is a large number of non-iodized salt entering the market after salt industry reform. So,we need to continue intensify monitoring and supervision,carry out health education,and ensure people consuming qualified iodized salt.
