摘　　要：目的分析比较宁夏回族自治区(简称宁夏)孕妇食用盐碘含量和碘营养现状,为防治措施制定提供依据。方法2017-2020年,每年在宁夏银川市、石嘴山市、吴忠市、固原市、中卫市5个地区的22个县(市、区)各调查100名孕妇,采集家中盐样、尿样进行盐碘、尿碘检测。结果2017-2020年,共采集盐样8807份,盐碘中位数为24.6 mg/kg,碘盐合格率为91.59%(7838/8558),碘盐覆盖率为97.17%(8558/8807),合格碘盐食用率为89.00%(7838/8807),且合格碘盐食用率逐年上升(χ^(2)_(趋势)=248.47,P<0.001)。不同年份、地区间盐碘含量比较差异均有统计学意义(H=259.14、37.09,均P<0.001)。共采集孕妇尿样8107份,孕妇尿碘中位数为165.00μg/L,达到适宜水平。不同地区、孕期间孕妇尿碘中位数及构成情况比较差异均有统计学意义(H=28.87、17.91,均P<0.001;χ^(2)=85.89、20.59,均P<0.05)。结论宁夏孕妇碘盐覆盖率较高,尿碘水平总体处于适宜状态。但对存在碘缺乏风险的孕妇,应重点干预,采取针对性补碘措施。Objective To analyze and compare the salt iodine content and iodine nutrition status of pregnant women in Ningxia Hui Autonomous Region(Ningxia for short),and to provide basis for formulation of prevention and control measures.Methods From 2017 to 2020,100 pregnant women were surveyed each year in 22 counties(cities,districts)in Yinchuan,Shizuishan,Wuzhong,Guyuan and Zhongwei of Ningxia,salt samples and urine samples were collected for salt iodine and urinary iodine detection.Results Totally 8807 salt samples were collected,the median salt iodine was 24.6 mg/kg.The qualified rate of iodized salt was 91.59%(7838/8558),the coverage rate of iodized salt was 97.17%(8558/8807),and the consumption rate of qualified iodized salt was 89.00%(7838/8807).The consumption rate of qualified iodized salt increased year by year(χ^(2)_(trend)=248.47,P<0.001).There were statistical differences in salt iodine levels in different years and regions(H=259.14,37.09,P<0.001).Totally 8107 urine samples were collected,the median urinary iodine of pregnant women was 165.00μg/L,which reached the appropriate level.The median and composition of urinary iodine were statistically different in different regions and pregnancies(H=28.87,17.91,P<0.001;χ^(2)=85.89,20.59,P<0.05).Conclusions The coverage rate of iodized salt among pregnant women in Ningxia is high,and the urinary iodine level is generally in a suitable state.However,for pregnant women at risk of iodine deficiency,special attention should be paid and targeted iodine supplementation measures should be taken.
