2012~2013年广饶县新标准碘盐试点监测结果

Monitoring Results in the Pilot New Standard Iodized Salt,Guangrao County,2012-2013

目的 了解掌握试点区域置换新标准碘盐后儿童、孕妇等重点人群的碘营养状况,为山东省乃至全国调整食用盐碘含量标准提供科学依据。方法 2012年4月至2013年3月对广饶县试点镇稻庄镇随机抽取孕妇和中心小学8~10岁在校学生,并进行食盐碘、尿碘与食盐食用量监测基线调查、新标准碘盐置换试点监测结果分析。结果 基线调查居民食盐样品245份,碘含量〉5mg/kg盐样240份,碘盐覆盖率为97.96%、碘含量20~50mg/kg盐样229份,碘盐合格率为95.42%、合格碘盐食用率93.46%。碘盐监测结果中位数为38.31mg/kg。儿童尿碘监测结果中位数为268.10μg/L。孕妇尿碘监测结果中位数为181.11μg/L。居民家中日食盐食用量平均数为6.25g/人。三次评估居民食盐样品分别为251、231、249份,碘盐覆盖率均为100.00%,碘盐合格率分别为100.00%、98.70%、100.00%,合格碘盐食用率分别为100.00%、98.70%、100.00%,碘盐监测结果中位数分别为30.80、28.31、24.46mg/kg。儿童尿碘监测结果中位数分别为266.90、256.81、230.06μg/L。孕妇尿碘监测结果中位数分别为189.35、179.01、203.50μg/L。居民家中日食盐食用量平均数分别为6.52、6.18、6.37g/人。结论 新旧标准碘盐置换后,重点人群儿童、孕妇尿碘监测结果一年内未发生显著改变,碘营养状况呈适宜状态。

Objective To understand the iodine nutritional status of children, pregnant women and other key groups in the pilot area after the replacement of the new standard of iodized salt,so as to provide the scientific basis for adjusting the salt iodine content standards in Shandong province and even in China. Methods During April,2012 -March,2013,pregnant women from Daozhuang township, the pilot township,and 8 10 years old primary school students from the Township Central School were recruited in Guangrao county, to conduct salt iodine, urinary iodine and salt consumption monitoring baseline survey,and new standard iodized salt replacement pilot monitoring result analysis. Results Of 245 iodine salt samples in the baseline survey among residents,240 salt samples 〉 5 mg/kg,with the iodized salt coverage of 97.96%, 229 salt samples 20 50 mg/kg,the qualified rate of iodized salt was 95.42 ~, the rate of qualified iodized salt consumption was 93.46 %. In the iodized salt monitoring results, the median was 38.31 mg/kg. In the urinary iodine monitoring results, the median was 268. 10 μg/L among children,and 181.11 μg/L among pregnant women. The average daily salt intake was 6.25 g/person. In three times evaluation, the residents＂ salt samples were respectively 251,231, and 249, with the iodized salt coverage of 100.00 %, the qualified rate of iodized salt was 100.00 %,98.70 %, and 100.00 %, the qualified iodized salt consumption rate was 100.00%, 98.70% and 100.00% respectively, the median of iodized salt monitoring results was 30.80,28.31,and 24.46 mg/kg. The median of children＇s urine iodine monitoring results was 266.90,256.81,and 230.06μg/L. The median of pregnant women urine iodine monitoring results was 189.35,179.01, and 203.50μg/L. The resi- dents＇ average daily salt consumption at home was 6.52,6.18,and 6.37 g per person. Conclusion After the replacement between the old and the new standards of iodized salt, the results of urinary iodine among children and pregnant women in the key groups have no significant changes within a year,the iodine nutrition status is in an optimal state.
