目的通过对张家口市2008-2012年度碘盐监测数据的综合分析,评价当前我市碘盐质量,同时对存在问题提出改进建议。方法按照卫生部《全国碘缺乏病监测方案》碘盐监测的要求进行,各县(区)每月对本辖区内碘盐加工(批发)层次抽取1批9份盐样;居民户盐:每县(区)按东、南、西、北方位各抽取两个乡,中区抽取一个乡,每乡抽取4个行政村,每村8份户盐,采用直接滴定法定量测定碘含量。结果碘盐加工(批发)层次:2008-2012年全市共监测960批次,合格925批次,批质量合格率为96.35%,监测盐样8640份,合格8454份,份数合格率97.85%。居民户盐层次:2008-2012年全市共监测739个乡(镇、街道办事处),2990个村(居委会);采集盐样24571份,其中合格23722份,碘盐合格率96.55%,碘盐覆盖率96.27%,合格碘盐食用率96.10%,非碘盐率0.72%,盐碘中位数28.56mg/kg。结论各项碘盐质量指标均位于国家控制指标以内,且保持在较为稳定的水平。碘盐质量从源头上得到了治理,加碘不足或加碘不匀现象得到了纠正。非碘盐历年都有检出,成为影响碘缺乏病防治效果的主要因素,应加大监测、监督力度,普及健康教育知识,遏止非碘盐的泛滥。
Objective Through the comprehensive analysis of monitoring data of iodized salt in 2008 ~ 2012 in Zhangjiakou City, evaluate the current quality of iodized salt in our city and put forward suggestions for improvement on the existing problems. Methods According to the requirements of iodine salt monitoring of “National Iodine Deficiency Disease Surveillance Program” issued by the Ministry of Health, each county (district) draws 1 batch of 9 salt samples from the processing (wholesale) level of iodized salt in its jurisdiction on a monthly basis; (Districts), two townships were taken from the east, the south, the west and the north. One village was taken from the central area and four administrative villages were taken from each township. Eight households were salt in each village. The iodine content was determined by direct titration. Results Level of iodized salt processing (wholesale): From 2008 to 2012, a total of 960 batches were approved and 925 batches were approved. The qualified rate of batch quality was 96.35%, 8640 salt samples were monitored, 8454 samples were qualified, and the passing rate of 97.85% of the shares. Residents’ household salt levels: In 2008-2012, a total of 739 townships (towns and sub-district offices) and 2990 villages (neighborhood committees) were monitored in the city. A total of 24,571 salt samples were collected, of which 23,722 were qualified, with iodized salt passing rate of 96.55% and iodized salt The coverage rate was 96.27%, the qualified iodized salt consumption rate was 96.10%, the non-iodized salt rate was 0.72%, and the median salt iodine concentration was 28.56mg / kg. Conclusion The quality indicators of iodized salt are all within the state control index, and remain at a relatively stable level. The quality of iodized salt has been governed at its source, and iodine deficiency or iodine imbalance has been corrected. Non-iodized salt has been detected over the years, becoming a major factor affecting the prevention and treatment of iodine deficiency disorders, monitoring and supervision should be increased efforts to popularize health education to prevent the proliferation of non-iodized salt.
