摘　　要：目的分析2019—2023年尉氏县儿童和孕妇碘营养状况,为制定碘缺乏病防控策略提供科学依据。方法2019—2023年每年在开封市尉氏县抽取200名8~10岁儿童和100名孕妇作为研究对象,分别采集儿童、孕妇随机尿样1次和家中食用盐盐样,检测尿碘和盐碘含量;测定儿童甲状腺容积,筛查甲状腺肿,计算甲状腺肿大率。结果2019—2023年尉氏县1000份8~10岁儿童尿样中,尿碘中位数分别为114、139、166、142、177μg/L,按尿碘频数分布,100~<200μg/L最多,占44.70%;500份孕妇尿样中,尿碘中位数分别为189、166、212、237、194μg/L,按尿碘频数分布,150~250μg/L最多,为52.60%。儿童和孕妇碘营养水平均为适宜。1000名8~10岁儿童甲状腺肿大率为0.90%。碘盐覆盖率为98.27%,合格碘盐食用率为94.71%。结论2019—2023年尉氏县儿童和孕妇碘营养均处于适宜水平,8~10岁儿童甲状腺肿大率<5%,达到了国家碘缺乏病消除标准,建议继续实行食盐加碘为主的碘缺乏病防控策略,加强重点人群监测。Objective To analyze iodine nutrition status among the children and pregnant women in Weishi County from 2019 to2023,soastoprovideascientific basis forformulating thepreventionandcontrol strategyof iodinedeficiencydiseases.Methods From 2019 to 2023,200 children aged 8-10 years and 100 pregnant women were selected from Weishi County,Kaifeng City every year as research subjects.Random urine samples and salt samples at home were collected from children and pregnant women to detect urine iodine and salt iodine content.Thyroid volume in children was measured;thyroid nodules were screened,and goiter rate was calculated.Results From 2019 to 2023,among the 1000 urine samples of children aged 8-10 years in Weishi county,the median urinary iodine levels were 114,139,166,142 and 177μg/L,respectively,and the frequency distribution of 100-<200μg/L was highest,accounting for 44.70%.Among the 500 urine samples of pregnant women,the median urinary iodine levels were189,166,212,237 and 194μg/L,respectively,and the frequency distribution of 150-<250μg/L was highest,accounting for52.60%.Iodine nutrition levels were appropriate in both children and pregnant women.The rate of goiter in 1000 children aged8-10 years was 0.90%.The coverage rate of iodized salt was 98.27%,and the consumption rate of qualified iodized salt was94.71%.Conclusions From 2019 to 2023,the iodine nutrition among the children and pregnant women in Weishi County were at an appropriate level.The goiter rate of children aged 8-10 years was<5%,which met the national standard for the elimination of iodine deficiency diseases.It is suggested to keep implementing the iodine deficiency disease prevention and control strategy mainly based on salt iodization,and strengthening monitoring of key populations.
