摘要
目的调查贵州省遵义市实施新的盐碘含量后居民碘营养水平。方法2014年采用随机数字表法在遵义市抽取4个县（区）开展居民碘营养监测，在每个县（区）抽取50名8—10岁儿童和20名孕妇作为监测对象，采用B超法检测儿童甲状腺肿大情况，并测定监测对象即时尿样含碘量，以及儿童家中食用盐含碘量。结果共检测200名8～10岁儿童甲状腺，甲状腺肿大率为1％（2／200）；共检测200份盐样，居民户合格碘盐食用率为96％（192／200）；共检测儿童尿样200份，尿碘中位数为229．3μg／L；共检测孕妇尿样80份，尿碘中位数为183．7μg／L。结论新的食盐碘含量标准实施后，遵义市4个县（区）儿童的碘营养状况仍然偏高，而孕妇的碘营养水平出现不平衡状况，建议针对不同人群供应不同含碘量食盐，加强监测，避免碘缺乏病的危害，真正做到科学补碘。
Objective To understand the city residents＂ iodine nutrition level after implementation of a new iodine concentration standard. Methods Using random sampling, four counties were selected to monitor iodine nutrition level; in every county 50 children aged 8 - 10 and 20 pregnant women were selected as monitoring subjects; B ultrasound scan was used to detect goiter and children urinary iodine and salt iodine levels were tested; urinary iodine concentration of pregnant women and nursing mothers was determined. Results Thyroid of 200 children aged 8 - 10 years were detected, the enlargement rate of thyroid gland was 1% （2/200）; 200 salt samples were tested, qualified iodized salt consumption rate was 96% （192/200）; 200 copies of children urine samples were tested, the median of urinary iodine was 229.3 μg/L; 80 copies urine samples of pregnant women were tested, urinary iodine median was 183.7 μg/L. Conclusions After implementation of a new standard of salt iodine content, the iodine nutrition level of children in the four counties （districts） of Zunyi is still high, but the level of iodine nutrition of pregnant women appears imbalanced. We suggest to supply different concentrations of iodized salt for different groups of people, to strengthen the monitoring, and to prevent iodine deficiency disorders.
