2020-2022年济南市济阳区儿童及孕妇碘营养水平分析

Analysis of Iodine Nutrition Level of Children and Pregnant Women in Jiyang District,Jinan City from 2020 to 2022

目的:分析济南市济阳区8~10岁儿童、孕妇的尿碘水平,反映其碘营养水平,为预防碘缺乏症和科学补充碘提供依据。方法:根据济南市方案要求,按照东、西、南、北方向划分为5个区域,每个区域选取1所小学并随机抽取40名8~10岁学龄儿童,并在每个抽样区域抽20名孕妇,采集尿样,检测尿碘含量。2020—2022年共抽取8~10岁儿童尿样、孕妇尿样共1561份,其中儿童尿样1230份,孕妇尿样331份,按照《尿中碘的测定第1部分:砷铈催化分光光度法》(WS/T107.1—2016)的方法检测尿碘含量,并加以分析。结果:2020年至2022年总计1561份尿样,2020—2022年中位数分别为267μg·L^(-1)、224μg·L^(-1)、248μg·L^(-1),其中低于100μg·L^(-1)的占7.9%;尿碘值为100~199μg·L^(-1)的占28.1%;尿碘值为200~299μg·L^(-1)的占29.5%,>300μg·L^(-1)的占34.5%,其中儿童组的尿碘中位数分别是298μg·L^(-1)、238μg·L^(-1)、266μg·L^(-1),碘缺乏者占比为5.4%,碘过量者占比为40.1%。孕妇尿碘的中位数分别是150μg·L^(-1),182μg·L^(-1),178μg·L^(-1),碘缺乏者占比为40.5%,碘过量者占比为1.8%,结论:济南市济阳区儿童、孕妇的碘营养现况良好。但儿童尿碘水平处于高位,有碘过量风险的儿童占比重比较大。孕妇尿碘水平偏低,较大部分孕妇处于碘缺乏的状态,应引起注意。

Objective:To analyze the urinary iodine level of children and pregnant women in Jiyang District,Jinan city,to reflect their iodine nutrition level,and to provide a basis for the prevention of iodine deficiency and scientific iodine supplementation.Method:According to the requirements of the Jinan plan,it was divided into 5regions according to the east,west,south and north directions.One primary school was selected and 40 school-age children aged 8~10 were randomly selected,and 20 pregnant women were selected in each sampling area to collect urine samples and detect urine iodine content.From 2020 to 2022,a total of 1561 urine samples and pregnant samples from children aged 8~10 years,including 1230 urine samples and 331 pregnant urine samples were collected and analyzed according to the method of WS/T107.1—2016.Result:for a total of 1561 urine samples from 2020 to 2022,The median value from 2020 to 2022 was 267μg·L^(-1),224μg·L^(-1),and 248μg·L^(-1),respectively,Of these,7.9% were less than 100μg·L^(-1),28.1%had 100μg·L^(-1)to 199μg·L^(-1),29.5%had urinary iodine values between 200 and 299μg·L^(-1),>300μg·L^(-1)accounted for 34.5%,The median urinary iodine value in the pediatric group was 298μg·L^(-1),238μg·L^(-1),and 266μg·L^(-1),iodine deficiency accounted for 5.4%,the proportion of iodine overdose was 40.1%.The median urinary iodine in the pregnant women group was 150μg·L^(-1),182μg·L^(-1)and 178μg·L^(-1),respectively.The proportion of iodine deficiency was 40.5%,and iodine excess was 1.8%.Conclusion:The iodine nutrition of children and pregnant women in Jiyang district of Jinan city was good.However,the urinary iodine level of children is high,and the proportion of children at risk of iodine excess is relatively large.The urinary iodine level of pregnant women is low,and most pregnant women are in a state of iodine deficiency,which should be paid attention to.
