目的了解广西乐业县高寒山区居民近几年来食用碘盐的情况,为消除碘缺乏病提供科学依据。方法按照《广西碘缺乏病项目实施方案》,对各乡镇居民食用碘盐进行随机抽样检测。按照GB/T 13025.7—2012《制盐工业通用试验方法碘离子的测定》中的方法,采用直接滴定法测定碘离子;根据GB 5461—2000《食用盐》中的方法对测定结果进行判定。结果 2008年-2015年共检测碘盐2 400份,碘含量为7.22 mg/kg~47.93 mg/kg,碘含量的中位数为25.23 mg/kg,未检出非碘盐,总合格率为97.04%,碘盐覆盖率为100%。结论乐业县合格碘盐食用率已达到符合《碘缺乏病消除标准》的要求,应继续按照《碘缺乏病防治项目实施方案》进行全民食用碘盐防治碘缺乏病,以巩固本县碘缺乏病防治成果,保障人民群众的身体健康。
Objective To understand the situation of the consumption of iodized salt in the alpine mountainous area of Leye County in Guangxi in recent years and provide a scientific basis for the elimination of iodine deficiency deficiency. Methods According to “Implementation Plan of Guangxi Iodine Deficiency Disease Project”, random sampling of iodized salt was conducted for all towns and villages. In accordance with GB / T 13025.7-2012 “Salt Industry General Test Method for Determination of Iodine,” Determination of iodide by direct titration; Determination of the results according to GB 5461-2000 “edible salt” in the method. Results A total of 2 400 iodized salt were detected during 2008-2015. The iodine content was 7.22 mg / kg ~ 47.93 mg / kg and the median iodine content was 25.23 mg / kg. Non-iodized salt was not detected. The total qualification rate was 97.04%, iodized salt coverage of 100%. Conclusion Leye County qualified iodized salt consumption rate has reached the “meet the” criteria for the elimination of iodine deficiency disorders, “should continue in accordance with the” iodine deficiency disorders prevention and treatment project implementation plan "universal iodized salt iodine deficiency disease prevention and control in order to consolidate the county iodine deficiency Disease prevention and treatment results to protect the health of the people.
