内蒙古少数民族地区孕妇及乳母碘营养状况调查

目的了解内蒙古通辽地区孕妇、乳母碘营养状况，为指导本地区孕妇、乳母科学补碘提供依据。方法2011年，按照《全国碘缺乏病监测方案》中的抽样和检测方法，在随机抽样中选择8个旗县（市、区），重点抽样选择2个旗县及2010～2011年各级盐业公司生产的部分碘盐，随机抽样监测采用直接滴定法（GB／T13025．7—1999）定量测定碘盐；重点抽样监测采用半定量法检测碘盐。共抽检120名孕妇、哺乳期妇女和400名8～10岁儿童尿样，采用过硫酸铵消化砷铈催化分光光度法测定尿碘。采用触诊法检查3963名8～10岁学龄儿童甲状腺肿大情况。结果共检测居民食用盐2328份，其中非碘盐率0．41％，碘盐覆盖率99．59％，碘盐合格率99．11％，合格碘盐食用率98．71％，碘盐中位数31．4mg／kg。重点抽样检测食用盐600份，碘盐覆盖率98．17％，非碘盐率1．84％。共检测120名孕妇、哺乳期妇女及400名8～10岁儿童的尿碘，其中孕妇尿碘中位数345．23μg／L，哺乳期妇女尿碘中位数245．07μg／L，8～10岁儿童尿碘中位数328．3μg／L。共抽检3963名8—10岁学龄儿童，检出甲状腺肿大106名，肿大率2．67％。结论通辽地区碘缺乏病防治工作取得了明显成效，各项指标均达到国家碘缺乏病消除标准。

Iodine nutritional status survey on pregnant women and lactating women in Inner Mongolia minority areas

Objective To master status and the condition of iodine nutritional status survey on pregnant women and lactating women, to provide the basis for iodine supplement on pregnant women and lactating women scientifically. Methods In 2011 , according to the ＂the National Iodine Deficiency Disorders Monitoring Program＂, to select iodized salts from 8 counties （ city, area） among the random samplings and 2 counties （city, area） and the important samplings from salt industry company at all levels in 2010 to 2011, using direct titration method to monitor salt iodine content（ GB/T 13025.7 - 1999） and quantitative determination of iodized salt; Intensive sampling detection of iodized salt monitoring using semi - quantitative method. In 2011, sampling a total of 120 pregnant women and breast - feeding women, 400 children aged from 8 to 10, using the method of ammonium persulfate di- gestion arsenic cerium catalytic spectrophotometry to determine urine iodine, palpation method to test goiter rate in 3 963 school - children aged 8 to 10 years. Results The salt samples of detected residents in the city were 2 328, non - iodized salt rate 0. 41%, iodized salt coverage rate 99.59%, the qualified rate of iodized salt was 99.11%, the qualified rate of iodized salt con- sumption 98.71%, median 31.4 mg/kg. Intensive sampling detection of edible salts were 600, iodized salt coverage rate 98. 17%, non - iodized salt rate 1.84%. Detecting urine iodine from a total of 120 pregnant women and breast - feeding women , 400 children aged from 8 to 10, the pregnant women＇ s urine median iodine 345.23 μg/L; Lactating women 245.07 μg/L; 8 to 10 years old children 328.3 μg/L, and sampling a total of 3 963 school - children aged 8 to 10, detection of goiter 106, goiter rate was 2.67%. Conclusion The prevention of IDD in Tongliao city achieved obvious resuh. All the indicators reached the national standard of IDD elimination.
