摘　　要：目的了解潍坊市盐碘浓度调整后居民碘营养状况。方法 2014年4月按照整群随机抽样方法,在潍坊市8个县（市）区抽取1 600名8~10岁儿童、400名孕妇和400名哺乳期妇女,采集随意即时尿样检测尿碘浓度;并应用B超检测儿童甲状腺容积。结果 2014年潍坊市抽取的儿童中甲状腺肿大5人,肿大率为0.31%。儿童、孕妇和哺乳期妇女尿碘中位数分别为195.90、134.00和121.40μg/L;县级居民尿碘中位数分别为165.45~227.35、96.10~208.02和80.55~286.70μg/L;不同县（市）区尿碘差异有统计学意义（P〈0.05）;所有县（市）区儿童尿碘中位数〉100μg/L,37.50%的县（市）区儿童尿碘中位数〉200μg/L,75.00%的县（市）区孕妇尿碘中位数〈150μg/L,37.50%的县（市）区哺乳期尿碘中位数〈100μg/L。结论山东省碘盐浓度调整后,潍坊市儿童和哺乳期妇女碘营养水平总体适宜,碘盐含量标准不宜再下调;孕妇碘营养不足。Objective To understand the current iodine nutritional status among the residents in Weifang city after the adjustment of salt iodine content. Methods In accordance with the cluster random sampling method, the MIC records from 1 600 children aged 8-10,400 pregnant women, and 400 lactating women from 8 districts and counties in Weifang city were collected randomly and instantly only once as samples, while children＇s thyroid volumes were calculated by ultrasound B. Results In 2014,5 out of 1 600 children in the urine test suffered from goiter,with the prevalence of 0.31%. The re- spective medians for the urine iodine levels of the three tested groups above were 195.90 μg/L, 134. 00μg/L,and 121.40 μg/L. The respective MMIs for three tested groups from different counties and districts ranged from 165.45-227.35 μg/ L,96.10-208.02 μg/L,and 80.55-286.70 μg/L. The differences between the respective urine iodine levels in those three tested groups from different counties and districts had statistical significance （ P 〈0.05）. The MMIs of all the tested chil- dren were above 100 μg/L,the medians of 37.50% of them were above 200 μg/L. As for 75% pregnant women from all o- ver Weifang city,their MMIs were below 150 μg/L,with 37.5% lactating women＇s MMIs below 100 μg/L. Conclusion The iodine nutritional status among the children and lactating women is satisfactory after the adjustment of salt iodine con- tent. Thus the standards for body iodine concentration of these two groups should be maintained. However, the pregnant women are still in demand of more iodine.
