摘　　要：目的掌握陕西省盐碘含量调整后儿童和孕妇的碘营养现状,为防治碘缺乏病提供科学依据。方法2018年,依据地形分布将陕西省107个县(市、区)划分为关中、陕北和陕南3个地区进行碘营养监测。其中,每个监测县(市、区)按东、西、南、北、中划分5个抽样片区,每个片区抽取1个乡镇(街道),每个乡镇(街道)抽取42名8~10岁非寄宿儿童(年龄均衡,男、女各半)和21名孕妇,采集家中食用盐盐样和随机尿样,检测盐碘和尿碘含量及儿童甲状腺肿大情况。结果共采集8~10岁儿童和孕妇家中食用盐盐样34264份,盐碘中位数为23.80 mg/kg,合格碘盐食用率为96.98%(33229/34264);其中,关中、陕北、陕南3个地区间食用盐盐碘中位数、合格碘盐食用率比较差异均有统计学意义(H=26.471,χ^2=32.371,P均<0.05)。共采集儿童尿样22895份,尿碘中位数为218.00μg/L,处于碘营养超适宜水平;孕妇尿样11369份,尿碘中位数为181.03μg/L,处于碘营养适宜水平;其中,关中、陕北、陕南地区的孕妇尿碘中位数分别为186.39、177.52、176.00μg/L。共检查8~10岁儿童甲状腺22895人,甲状腺肿大率为1.35%(309/22895),3个地区间比较差异无统计学意义(χ^2=3.395,P>0.05)。结论陕西省达到持续碘缺乏消除标准,儿童碘营养处于超适宜水平,孕妇处于适宜水平。Objective To master the iodine nutrition status of children and pregnant women after adjustment of salt iodization content in Shaanxi Province,and provide scientific basis for preventing and treating iodine deficiency disorders.Methods In 2018,107 counties(cities,districts)in Shaanxi Province were divided into three districts in Guanzhong,northern Shaanxi and southern Shaanxi for studying iodine nutrition based on terrain distribution.Among them,each monitoring county(city,district)was further divided into 5 sampling areas according to east,west,south,north,and middle locations.One township(street)was selected in each location,and forty-two 8-10 years old non-boarding children(age and sex balanced)and 21 pregnant women were selected in each township(street),edible salt samples and random urine samples were collected for salt iodine,urinary iodine testing,and goiter of children was examined.Results A total of 34264 edible salt samples from 8-10 years old children and pregnant women were collected,the median salt iodine was 23.80 mg/kg,and the qualified iodized salt consumption rate was 96.98%(33229/34264).The median salt iodine and the qualified iodized salt consumption rate were statistically significantly different among the three regions in Guanzhong,northern Shaanxi,and southern Shaanxi(H=26.471,χ^2=32.371,P<0.05).A total of 22895 urine samples were collected from children,with a median urinary iodine of 218.00μg/L,which was at an ultra-suitable level of iodine nutrition;and 11369 urine samples from pregnant women were collected,with a median urinary iodine of 181.03μg/L,which was at an appropriate level of iodine nutrition.The median urinary iodine of pregnant women in Guanzhong,northern Shaanxi,and southern Shaanxi was 186.39,177.52,and 176.00μg/L,respectively.A total of 22895 children aged 8 to 10 years old were examined,the goiter rate was 1.35%(309/22895),and there was no significant difference between different regions(χ^2=3.395,P>0.05).Conclusions Shaanxi Province has reached the standard for elimi
