某市2002年、2004年碘盐监测结果对比分析

目的 了解HZ市碘盐生产加工和居民食用碘盐情况，为防治碘缺乏病采取有效措施提供科学依据。方法 用“五方位”抽样法分别对生产层次碘盐和居民户层次的家庭食用盐进行抽样，用直接滴定法检测盐碘。结果 2002与2004年碘盐监测结果相比较，碘盐变异系数值由21％下降至17．5％：居民户非碘盐率由10．39％上升为14．65％；碘盐覆盖率由89．61％下降至85．35％；碘盐合格率由95．13％下降至86．32％：合格碘盐食用率由85．18％下降至74．48％。结论 生产层次的碘盐加工质量在不断提高。非碘盐冲销病区的问题日益严重。建议各有关部门继续加大打击非碘盐冲销市场的力度，继续加强对全民宣传碘缺乏病的危害和食盐加碘预防碘缺乏病的健康教育工作。

Monitoring of Iodized Salt in Huizhou in 2002 and 2004

Objective To investigate the conditions of processing of iodized salt and iodized salt consumption in the general population in Huizhou, and to provide-scientific basis for prevention of IDD. Methods The conditions of processing of iodized salt and iodized salt consumption in the population were studied by cluster sampling. Iodized salt was tested by means of titration neutralization. Results The data of monitoring in 2002 with those in 2004 was compared. The variation coefficient of iodized salt dropped from 21.0% to 17.5% ; the rate of non- iodized salt consumption was increased from 10.39% to 14.65% ; the covering rate of iodized salt consumption in the population was decreased from 89.61% to 85.35%; the passing rate of iodized salt was dropped from 95.13% to 86.32%; the rate of consumption of qualified iodized salt in the population was dropped from 85.1.8% to 74.48. Conclusion The quality of processed iodized salt is improving. However, the non-iodized salt was floated the market of the disease areas. Counter measures to the sale of non-iodized salt should be implemented and should promote the health education of the population.
