摘　　要：目的了解甘肃省人群碘营养状况和碘缺乏病防治效果,为下一步科学补碘提供依据。方法在全省14个市(州) 86个县(区)共87个监测单位开展监测。在61个县每个监测县按东、西、南、北、中划分5个抽样片区,每个片区各随机抽取1个乡镇(街道),每个乡镇(街道)各抽取1所小学,每所小学抽取8~10岁非寄宿学生40人,采集学生尿样和家中食用盐,检测尿碘、盐碘含量,采用B超检测学生甲状腺容积;在所抽取的5个乡中每乡抽取20名孕妇,采集孕妇尿样和家中食用盐,检测尿碘、盐碘含量。在27个县区每个监测县按东、西、南、北、中划分5个抽样片区,在每个片区各随机抽取1个乡镇(街道),在每个乡镇(街道)随机抽取4个行政村,随机抽检15户居民食用盐,检测盐碘含量。结果共调查8~10岁儿童12 322名、孕妇6 112名;8~10岁儿童尿碘中位数为189.1μg/L,各地区尿碘中位数在153.5~271.4μg/L间;孕妇尿碘中位数为168.7μg/L,各地区尿碘中位数在129.9~238.4μg/L间;8~10岁儿童甲状腺肿大率为2.0%;盐碘中位数25.22 mg/kg,碘盐覆盖率98.94%,合格碘盐食用率93.16%。结论甘肃省整体碘缺乏病处于持续消除状态,合格碘盐食用率持续下降;儿童碘营养处于适宜水平,但部分地区孕妇碘营养不足。Objective To understand the iodine nutritional status of population and the prevention and control effect of iodine deficiency disorders( IDD) in Gansu Province,and to provide a scientific basis for iodine supplementation.Methods There are 87 monitoring units in 86 counties( districts) of 14 cities( prefectures) in the province.In 61 counties,each county,5 townships were randomly selected according to their sub-area positions of east,west,south,north and center;One primary school was chosen in each township by the randomized sampling method,40 students in each school were sampled for examining their thyroid volume,tested for their urinary iodine content and their household salt iodine content;20 pregnant women in each township were sampled to test their urinary iodine content and their household salt iodine content.In 27 counties,each monitoring county is divided into 5 sampling areas according to east,west,south,north and center;One township( town) is randomly selected in each area,and four administrative villages are randomly selected in each township( town).15 households of residents are randomly sampled for salt iodine content detection.Results A total of 12 322 children aged 8 to 10 years and 6 112 pregnant women were investigated. The median urinary iodine( MUI) of children was 189.1 μg/L,the MUI in each city was between 153.5 μg/L and 271.4 μg/L;the MUI of pregnant women was168.7 μg/L,the MUI in each city was between 129.9 μg/L and 238.4 μg/L;the children’ s goiter rate was 2.0%;the median of salt iodine was 25. 22 mg/kg, coverage rate of iodized salt was 98. 94%, consumption rate of qualified iodized salt was 93. 16%.Conclusion IDD is in a state of continuous elimination in Gansu Province,the consumption rate of qualified iodized salt continues to decline;and the iodine nutrition of children is at an appropriate level,but the iodine nutrition of pregnant women is insufficient in some areas.
