摘要
目的了解安徽省定远县8~10岁儿童和孕妇人群尿碘监测结果,为制定改善碘营养措施提供科学依据。方法2021—2023年,每年在定远县东、西、南、北、中5个地理方位各随机抽取1个乡(镇、街道),每个乡(镇、街道)随机抽取40名8~10岁儿童和20名孕妇作为调查对象。采集调查对象的尿样检测尿碘含量,计算尿碘中位数,评价碘营养状况。结果定远县2021—2023年共调查8~10岁儿童600人,孕妇300人。600名8~10岁儿童尿碘中位数为297.27μg/L,其中<100μg/L 28人,占4.67%;100~199μg/L 98人,占16.33%;200~299μg/L 182人,占30.33%;≥300μg/L 292人,占48.67%。2021—2023年定远县8~10岁儿童尿碘中位数分别为300.44、258.60和346.32μg/L,差异有统计学意义(H=48.269,P<0.001)。300名孕妇尿碘中位数为223.13μg/L,其中<150μg/L74人,占24.67%;150~249μg/L 104人,占34.67%;250~499μg/L 114人,占38.00%;≥500μg/L 8人,占2.67%。定远县2021—2023年孕妇尿碘中位数分别为215.03、167.22和284.02μg/L,差异有统计学意义(H=37.407,P<0.001)。结论定远县8~10岁儿童和孕妇均存在碘缺乏及碘超过适宜量的风险。
Objective To understand the monitoring results of urinary iodine in children aged 8-10 and pregnant women in Dingyuan County,Anhui Province,and provide scientific basis for formulating measures to improve iodine nutrition.Methods From 2021 to 2023,one township(town,street)randomly selected from each of the five geographical directions of east,west,south,north,and middle in Dingyuan County each year.40 children aged 8-10 and 20 pregnant women were randomly selected from each township(town,street)as survey subjects.Urine samples were collected from survey subjects to detect urinary iodine content,the median urinary iodine was calculated,and iodine nutrition status was evaluated.Results A total of 600 children aged 8-10 and 300 pregnant women were surveyed in Dingyuan County from 2021 to 2023.The median urinary iodine level among 600 children aged 8-10 years old was 297.27μg/L,of which 28(4.67%)were below 100μg/L,98(16.33%)were between 100-199μg/L,182(30.33%)were between 200-299μg/L,and 292(48.67%)were above 300μg/L.The median urinary iodine levels for children aged 8-10 in Dingyuan County from 2021 to 2023 were 300.44,258.60,and 346.32μg/L,respectively,with statistically significant differences(H=48.269,P<0.001).The median urinary iodine level among 300 pregnant women was 223.13μg/L,of which 74(24.67%)were below 150μg/L,104(34.67%)were between 150-249μg/L,114(38.00%)were between 250-499μg/L,and 8(2.67%)were above 500μg/L.The median urinary iodine levels of pregnant women in Dingyuan County from 2021 to 2023 were 215.03,167.22,and 284.02μg/L,respectively,with statistically significant differences(H=37.407,P<0.001).Conclusion Children aged 8-10 and pregnant women in Dingyuan County are at risk of iodine deficiency and exceeding the appropriate amount of iodine.
