摘要：目的了解甘肃省陇西县8~10岁儿童和孕妇的碘营养状况。方法采用描述流行病学方法, 分析陇西县2017年水碘监测和2017—2023年碘缺乏病监测资料(均来源于甘肃省疾病预防控制中心地方病防治所), 内容包括水碘, 8~10岁儿童和孕妇盐碘、尿碘含量及儿童甲状腺B型超声检查结果等。依据《食盐加碘项目的监测和人群碘营养的判定指南》进行碘营养评价。结果 2017年共采集水样85份, 水碘中位数为1.6 μg/L, 范围为0.2 ~ 10.9 μg/L, 除1份水样碘含量为10.9 μg/L外, 其余水样碘含量均< 10 μg/L。2017—2023年共监测儿童1 585人、孕妇718人, 尿碘水平分别为190.8(120.2, 252.2)、137.0(79.8, 195.8)μg/L。各年份陇西县碘盐覆盖率范围为99.4%~100%, 合格碘盐食用率范围为61.8%~93.0%, 碘盐合格率范围为62.1%~93.0%。各年份儿童尿碘中位数范围为125.9~228.5 μg/L。不同年份儿童尿碘含量比较, 差异有统计学意义(P < 0.001);不同性别和年龄儿童尿碘含量比较, 差异均无统计学意义(均P > 0.05);不同年份、性别及年龄儿童碘营养状况构成比比较, 差异均有统计学意义(均P < 0.05)。各年份孕妇尿碘中位数范围为121.0~180.5 μg/L, 除2017年外, 其余年份孕妇尿碘中位数均< 150 μg/L。不同年份孕妇尿碘含量与碘营养状况构成比比较, 差异均有统计学意义(均P < 0.001);不同孕期孕妇尿碘含量与碘营养状况构成比比较, 差异均无统计学意义(均P > 0.05), 且孕早、中、晚期孕妇碘营养均处于缺乏状态(尿碘中位数均< 150 μg/L)。甲状腺B型超声共检查儿童665人, 各年份甲状腺肿大率范围为0~5.0%。结论 2017—2023年陇西县8~10岁儿童碘营养处于适宜状态, 而孕妇碘营养处于缺乏状态。
Objective To investigate the iodine nutrition status of children aged 8-10 and pregnant women in Longxi County,Gansu Province.Methods Descriptive epidemiological method was used to analyze the water iodine monitoring data in 2017 and the iodine deficiency disorders monitoring data from 2017 to 2023 in Longxi County(sourced from the Institute for Endemic Disease Prevention and Control of Gansu Provincial Center for Disease Control and Prevention),including the data of water iodine,salt iodine and urinary iodine levels of children aged 8 to 10 and pregnant women,and children's thyroid B-mode ultrasound examination results.lodine nutrition was evaluated based on the"Guidelines for Monitoring Salt Iodization Projects and Determining Population Iodine Nutrition".Results In 2017,a total of 85 water samples were collected,with a median iodine level of 1.6μg/L,ranging from 0.2 to 10.9μg/L.Except for one water sample with an iodine level of 10.9μg/L,the iodine level of all other water samples was less than 10μg/L.From 2017 to 2023,a total of 1585 children and 718 pregnant women were monitored.The urinary iodine levels were 190.8(120.2,252.2),137.0(79.8,195.8)μg/L,respectively.The coverage rate of iodized salt in Longxi County from 2017 to 2023 ranged from 99.4%to 100%,the consumption rate of qualified iodized salt ranged from 61.8%to 93.0%,and the qualified rate of iodized salt ranged from 62.1%to 93.0%.The median range of the urinary iodine for children in Longxi County was 125.9 to 228.5μg/L.There was a statistically significant difference in the urinary iodine levels among children from different years(P<0.001).There was no statistically significant difference in urinary iodine levels among children of different genders and ages(P>0.05).There were statistically significant differences in the composition ratio of iodine nutrition status among children of different years,genders,and ages(P<0.05).The median range of urinary iodine in pregnant women was 121.0-180.5μg/L.Except for 2017,the median urinary iodine of pregnant women in all other years was less than 150μg/L.There were statistically significant differences in the urinary iodine levels and composition ratio of iodine nutrition status among pregnant women in different years(P<0.001).There was no statistically significant difference(P>0.05)in the urinary iodine levels and composition ratio of iodine nutrition status among pregnant women during different stages of pregnancy,and all pregnant women were iodine deficient in the early,middle,and late stages(median urinary iodine<150μg/L).Six hundred and sixty-five children underwent B-mode ultrasound examination,with a goiter rate ranging from 0 to 5.0%.Conclusion From 2017 to 2023,the iodine nutrition of children aged 8 to 10 in Longxi County is in an appropriate state,while the iodine nutrition of pregnant women is in a deficiency state.
