目的综合分析2006～2010年大同市碘盐监测数据,及时掌握缺碘地区居民户碘盐普及情况,为适时采取针对性防治措施和科学调整干预策略提供依据。方法按《全国碘盐监测方案》规定的抽样方法及监测方法进行,在大同市11个县(区)每年按东、南、西、北、中5个方位各抽取1～2个乡镇,每乡镇抽取4个村,每村抽取8份盐样,采用直接滴定法定量测定含碘量。结果 2006～2010年监测大同市11个县(区)居民食用盐15 960份,碘盐覆盖率96.74%,碘盐合格率98.68%,合格碘盐食用率95.46%,非碘盐率3.26%,盐碘中位数为30.09 mg/kg。结论 5年中大同市碘盐各项质量指标均在国家控制指标以内,且保持在相对稳定的水平。但非碘盐历年都有检出,成为影响防治碘缺乏病的主要因素,因此相关部门应继续加大监测、监督工作力度,普及健康教育知识,遏制非碘盐的泛滥,实现消除碘缺乏病目标。
Objective To comprehensively analyze the monitoring data of iodized salt in Datong City from 2006 to 2010, and to grasp the popularization of iodized salt of residents in iodine-deficient areas in time so as to provide evidences for timely taking targeted prevention and control measures and adjusting intervention strategies scientifically. Methods According to the sampling method and monitoring method stipulated in National Iodized Salt Surveillance Program, 1 or 2 townships and townships were sampled from 11 counties (districts) in Datong each year in five orientations of east, south, west, north and south, each Township extraction 4 villages, each village extract 8 salt samples, using direct titration method for the determination of iodine content. Results From 2006 to 2010, 15 960 salt, salt iodine salt coverage, iodized salt rate of 98.68%, iodine salt rate of 95.46% and non-iodized salt rate of 3.26% were detected in 11 counties (districts) The median salt iodine was 30.09 mg / kg. Conclusion The quality indicators of iodized salt in Datong City within 5 years are all within the state control index and remain at a relatively stable level. However, non-iodized salt has been detected over the years, becoming a major factor affecting the prevention and treatment of iodine deficiency disorders, the relevant departments should continue to increase monitoring and supervision efforts to popularize health education knowledge to curb the proliferation of non-iodized salt to achieve the elimination of iodine deficiency disorders aims.
