摘　　要：目的了解甘肃省人群碘营养状况,为相关部门的政策调整提供科学依据。方法2019年,采用横断面调查方法,在甘肃省14个市(州)86个县(区、市)的87个监测单位进行碘缺乏病调查。采集8~10岁儿童和孕妇随意1次尿样和家中食用盐盐样,测定尿碘和盐碘含量;在其中40个监测单位,采用B超法测量儿童甲状腺容积。结果共调查8~10岁儿童17772名,尿碘中位数为197.4μg/L,14个市(州)尿碘中位数范围为160.6~233.4μg/L,不同性别、年龄儿童尿碘中位数比较差异均有统计学意义(P均<0.001);共对8269名儿童进行甲状腺容积检查,甲状腺肿大率为1.4%(118/8269),不同性别、年龄儿童甲状腺容积比较差异均有统计学意义(P均<0.05);共调查孕妇8605名,尿碘中位数为178.6μg/L,14个市(州)尿碘中位数范围为156.5~275.0μg/L,不同孕期孕妇尿碘中位数比较差异无统计学意义(P>0.05)。共调查儿童和孕妇家中食用盐盐样26377份,盐碘中位数为24.71 mg/kg,碘盐覆盖率、合格碘盐食用率分别为99.44%、93.59%;有23个县(区、市)单项指标未达到碘缺乏病消除标准。结论甘肃省碘缺乏病处于持续消除状态;碘盐监管有待进一步加强;地区间防治措施不平衡。Objective To investigate the iodine nutritional status of population in Gansu Province,and to provide a scientific basis for policy adjustment of relevant departments.Methods In 2019,a cross-sectional survey was conducted in 87 monitoring units in 86 counties(districts and cities)of 14 cities(prefectures)in Gansu Province for iodine deficiency disorders(IDD).Instant urine samples and salt samples of children aged 8 to 10 years and pregnant women were collected for detection of urinary iodine and salt iodine.B-ultrasound was used to check the thyroid volume of children in 40 monitoring units.Results A total of 17772 children aged 8 to 10 years were investigated.The median urinary iodine(MUI)of children was 197.4μg/L,the MUI of 14 cities(prefectures)ranged from 160.6 to 233.4μg/L.There were statistically significant differences in MUI among children of different genders and ages(P<0.001).Totally 8269 children were examined by B-ultrasound,the children's goiter rate was 1.4%(118/8269).There were statistically significant differences in the thyroid volume among children of different genders and ages(P<0.05).A total of 8605 pregnant women were investigated.The MUI of pregnant women was 178.6μg/L,and the MUI of 14 cities(prefectures)ranged from 156.5 to 275.0μg/L.There was no statistical significant difference in MUI among pregnant women in different pregnancies(P>0.05).A total of 26377 samples of salt consumed by children and pregnant women were detected.The median salt iodine was 24.71 mg/kg.The coverage rate of iodized salt and the consumption rate of qualified iodized salt were 99.44%and 93.59%,respectively.Twenty-three counties(districts and cities)failed to meet the elimination standard of IDD in the single indicator.Conclusions IDD is in a state of continuous elimination in Gansu Province;iodized salt supervision needs to be further strengthened;there is an imbalance of control measures between regions.
