摘要
目的 分析2018-2022年8～10岁儿童和孕妇碘营养水平,为科学补碘提供依据.方法 每年在万州区按东、西、南、北、中5个方位分别抽取1个乡镇/街道,每个乡镇/街道抽取8～10岁儿童及孕妇作为监测对象,采集家庭食用盐样和尿样检测碘含量;对2019年和2021年儿童采用B超进行甲状腺检查.结果 2018-2022年共监测儿童和孕妇1 545人,其中儿童1 040人,孕妇505人;儿童尿碘中位数在193.9～294.9 μg/L之间;孕妇尿碘中位数在151.8～202.8 μg/L之间.2018-2022年盐样共检测1545份,合格碘盐食用率分别为91.0％、94.6％、99.0％、96.7％、97.4％.儿童B超检查414人,甲状腺肿大率1.7％;儿童甲状腺容积与尿碘含量呈正相关(r=0.163,P＜0.05).结论 2018-2022年万州区8～10岁儿童和孕妇碘营养水平总体适宜;2022年儿童尿碘中位数高,应重点关注儿童尿碘水平变化,在预防碘缺乏的同时注意避免碘过量.
Abstract
Objective To analyze the iodine nutrition level among children aged 8 to 10 and pregnant women in Wanzhou District of Chongqing from 2018 to 2022,so as to provide scientific basis for iodine supplement.Methods The township/street was selected from five directions(east,west,south,north and center)in Wanzhou District each year,and children aged 8 to 10 and pregnant women were selected from the township/street as monitoring subjects.Their household salt and urine samples were collected for iodine detection.The thyroid of children was measured by B-ultrasound in 2019 and 2021.Results From 2018 to 2022,a total of 1 545 children and pregnant women were monitored,including 1 040 children and 505 pregnant women.The median urinary iodine of children ranged from 193.9 to 294.9 μg/L.The median urinary iodine of pregrant wamen ranged from 151.8 to 202.8 μg/L in pregnant women.A total of 1 545 salt samples were tested from 2018 to 2022,and the consumption rate of qualified iodized salt were 91.0％,94.6％,99.0％,96.7％and 97.4％,respectively.A total of 414 children's thyroid were measured by B-ultrasound,and the rate of goiter was 1.7％.The volume of thyroid was positively correlated with urinary iodine(r=0.163,P＜0.05)among children.Conclusion The iodine nutrition level among children aged 8 to 10 and pregnant women in Wanzhou District was generally appropriate from 2018 to 2022,the median urinary iodine of children was somewhat high in 2022,and more attention should be paid to the variation trend.It is necessary to avoid iodine excess while preventing iodine deficiency.
