摘　　要：目的 调查2020年渭南市重点人群碘营养状况,评价各县(市、区)碘缺乏病消除情况,为调整该地区碘缺乏病防治策略和措施奠定基础。方法 采用多阶段随机抽样方式,在每个县(市、区)抽取8~10岁儿童和孕妇,监测儿童盐碘、尿碘含量及甲状腺肿大情况和孕妇盐碘、尿碘含量。结果 2020年渭南市盐碘中位数为24.83 mg/kg,合格碘盐覆盖率为96.97%;儿童甲状腺肿大率触诊法和B超法分别为1.23%和0.75%;儿童尿碘中位数为257.38μg/L、孕妇尿碘中位数为179.61μg/L,除潼关县外,其他县均高于国家碘缺乏消除标准(150μg/L)。根据碘营养状况评价标准,渭南市儿童人群碘营养状况处于超适宜量摄入,潼关县儿童碘营养状况为适宜量摄入,临渭区、华阴市儿童碘营养状况为碘过量,其余各县均为大于适宜量摄入。渭南市孕妇碘营养状况为适宜量摄入,潼关县孕妇为轻度碘缺乏,尿碘中位数为148.84μg/L,且补碘率>90%。结论 综合渭南市居民合格碘盐食用率、儿童尿碘中位数和甲状腺肿大率等指标,市、县两个层面均维持了国家碘缺乏病消除标准,部分县、区儿童有碘营养过量的风险。Objective To lay the foundation for prevention and treatment of iodine deficiency disorder in Weinan in 2020 by investigating the iodine nutritional status of key populations and evaluating the eliminations of iodine deficiency disorder in counties(cities, districts).Methods The children aged 8-10 years and 21 pregnant women were selected from counties by multi-stage random sampling, the contents of salt iodine, urinary iodine and goiter of children as well as salt iodine and urinary iodine of pregnant women were monitored.Results The median of salt iodine in Weinan was 24.83 mg/kg, the coverage rate of qualified iodized salt was 96.97%,the goiter rate in children via palpation test and B-ultrasound test was 1.23% and 0.75%,respectively.The median urinary iodine in children and pregnant women was 257.38 μg/L and 179.61 μg/L,respectively, and such index in other counties was higher than the national criterion for iodine deficiency elimination(150 μg/L) except Tongguan County.According to the evaluation standard for iodine nutritional status, the iodine nutritional status of children in Weinan was beyond appropriate intake, such index of children in Tongguan County as well as Linwei District and Huayin City was in appropriate and excessive intakes respectively, and the iodine nutritional status of children in other counties was greater than the appropriate intake.The iodine nutritional status of pregnant women in Weinan was appropriate, such index of pregnant women in Tongguan County was mild iodine deficiency, the median urinary iodine of pregnant women in Tongguan County was 148.84 μg/L,and the iodine supplement rate was >90%.Conclusion National iodine deficiency disorder elimination standard is maintained at the city and county levels by summarizing edible rate of qualified iodized salt, median urinary iodine of children, and goiter rate and other indicators in Weinan.Children in some counties and districts suffer from overnutrition of iodine.
