摘　　要：目的分析江苏省水源性高碘地区重点人群碘营养状况,为科学防治水源性高碘危害提供参考依据。方法2020年5-6月,在江苏省6个高碘县(市、区)以行政村为单位确定监测点,采集居民饮用水水样检测水碘含量;每个村抽取1所小学的8~10岁非寄宿儿童40名(男女各半、年龄均衡)以及孕妇20名,采集儿童、孕妇家中食用盐盐样和随机1次尿样,检测盐碘、尿碘含量,并检查儿童甲状腺容积。结果共监测行政村36个,水碘中位数为45.3μg/L,范围为8.5~372.1μg/L。共采集居民家中食用盐盐样1422份,其中碘盐26份,占1.83%;未加碘食盐1396份,未加碘食盐覆盖率为98.17%。共采集儿童尿样1365份,尿碘中位数为405.6μg/L;不同地区、饮水碘含量、年龄组儿童尿碘比较,差异均有统计学意义(H=128.39、67.81、39.94,均P<0.001)。共采集孕妇尿样57份,尿碘中位数为282.0μg/L;不同地区、饮水碘含量组孕妇尿碘比较,差异均有统计学意义(H=17.54、18.39,均P<0.001)。检查儿童甲状腺容积1365例,检出甲状腺肿大44例,甲状腺肿大率为3.22%;不同地区、饮水碘含量、食盐类型、性别和年龄组儿童甲状腺肿大率比较,差异均无统计学意义(均P>0.05)。结论江苏省水源性高碘地区儿童碘营养处于碘过量水平,孕妇碘营养处于超适宜量水平。在水源性高碘地区,饮水碘含量对当地人群碘摄入量有较大影响,暂未见饮水碘含量、食盐类型、性别和年龄因素与儿童甲状腺肿大间存在相关性。Objective To analyze the iodine nutrition status of key populations in water source high iodine areas in Jiangsu Province,providing a reference for scientific prevention and control of water source high iodine hazards.Methods From May to June 2020,monitoring sites were determined by administrative villages in six high iodine counties(cities,districts)in Jiangsu Province,and drinking water samples were collected from residents to detect the iodine content in the water;40 non boarding children aged 8-10 from one primary school in each village(half male and half female,with an age balance)and 20 pregnant women were selected.Salt samples were taken from children and pregnant women's homes,and urine samples were randomly taken once to detect salt and urine iodine contents.Thyroid volume of children was examined.Results A total of 36 administrative villages were monitored,with a median of 45.3μg/L for water iodine,ranging from 8.5-372.1μg/L.A total of 1422 salt samples were collected,of which 26 were iodized salt,accounting for 1.83%;and 1396 non iodized salt,with the coverage rate of non iodized salt was 98.17%.A total of 1365 urine samples were collected from children,with a median urine iodine of 405.6μg/L.There were statistically significant differences in urine iodine levels among children in different regions,drinking water iodine contents,and age groups(H=128.39,67.81,39.94,P<0.001).A total of 57 urine samples were collected from pregnant women,with a median urine iodine of 282.0μg/L.There were statistically significant differences in urine iodine levels among pregnant women in different regions and drinking water iodine contents groups(H=17.54,18.39,P<0.001).A total of 1365 children's thyroid volumes were examined,and 44 cases of thyroid enlargement were detected,with a goiter rate of 3.22%.There were no statistically significant differences in the incidence of thyroid enlargement among children in different regions,drinking water iodine contents,salt types,gender,and age groups(P>0.05).Conclusions The iodi
