目的了解和掌握开化县碘盐现况,为进一步推动持续消除碘缺乏病工作提供科学依据。方法根据卫生部《全国碘盐监测方案(修订)》和《浙江省碘盐监测实施细则》进行抽样,采用直接滴定法(GB/T13025.7-1999)对采集的碘盐进行定量检测。结果2004~2008年共监测第一层次碘盐60批,批质量合格率100%,盐碘均值37.1 mg/kg,变异系数2.9%,标准差1.08 mg/kg;第二层次共监测18个乡(镇)居民食用盐1 440份,碘盐覆盖率99.4%,碘盐合格率98.8%,合格碘盐食用率98.2%,各年度的居民碘盐覆盖率、合格碘盐食用率达到90%以上。结论开化县总体上处于碘缺乏病可持续消除状态,但非碘盐冲击问题在局部地区依然存在,要进一步加强碘缺乏病的健康教育工作,确保居民正确食用合格碘盐。
Objective To understand and grasp the current situation of iodized salt in Kaihua County and provide a scientific basis for further promoting the continuous elimination of iodine deficiency disorders. Methods According to the “National Iodized Salt Surveillance Program (Revised)” and the “Implementation Rules of Iodized Salt Surveillance in Zhejiang Province” of Ministry of Public Health, direct iodometric method (GB / T13025.7-1999) was used for quantitative detection of iodized salt collected. Results A total of 60 batches of iodized salt were monitored during 2004-2008. The qualified rate of batch quality was 100%, the average iodized salt was 37.1 mg / kg, the coefficient of variation was 2.9% and the standard deviation was 1.08 mg / kg. The second level was 18 townships (Town) residents of salt 1 440, iodized salt coverage of 99.4%, iodized salt pass rate of 98.8%, qualified iodized salt consumption rate of 98.2%, the annual iodized salt coverage of residents, qualified iodized salt consumption rate of 90% or more . Conclusions Kaihua County is generally in a state of sustainable elimination of iodine deficiency disorders. However, non-iodized salt shocks still exist in some areas. Health education for iodine deficiency disorders should be further strengthened to ensure that residents can properly consume iodized salt.
