摘要
目的 了解2021-2022年内蒙古东部地区蒙古族和汉族孕妇碘营养状况,探讨影响碘营养状况的相关因素,为科学防控碘缺乏病提供依据.方法 在内蒙古自治区东部4市(盟)行政区域内选取5个抽样片区,每个片区随机选取蒙古族和汉族孕妇各15例,采集任意时段尿样与食用盐样,测定尿碘含量与盐碘含量,并向孕妇发放调查问卷.结果 蒙古族孕妇食用盐样盐碘中位数为24.10 mg/kg,碘盐覆盖率为99.45％,碘盐合格率为94.48％,合格碘盐食用率为93.96％;汉族孕妇食用盐样盐碘中位数为24.50 mg/kg,碘盐覆盖率为100.00％,碘盐合格率94.07％,合格碘盐食用率为94.07％.结论 蒙古族和汉族孕妇尿碘中位数(Medianurina-ryiodine,MUI)总体处于碘适宜水平,但是蒙古族孕妇与汉族孕妇均不同程度存在碘缺乏与碘过量的风险.
Abstract
Objective To understand iodine nutrition of pregnant women in eastern Inner Mongolia from 2021 to 2022.To explore the related factors affecting iodine nutrition status,and provide basis for scientific pre-vention and control of iodine deficiency diseases.Methods Five sampling areas were divided into four adminis-trative areas in the eastern part of Inner Mongolia Autonomous Region.A total of 15 pregnant women of Mongo-lian nationality and 15 pregnant women of Han nationality were randomly selected in each area.Urine samples and edible salt samples were collected at any time to determine urine iodine and salt iodine content,and question-naires were distributed to pregnant women.Results The median iodine of salt samples was 24.10 mg/kg,the coverage rate of iodized salt was 99.45％,the qualified rate of iodized salt was 94.48％,and the qualified rate of iodized salt was 93.96％.The median iodine of salt samples was 24.50 mg/kg,the coverage rate of iodized salt was 100％,the qualified rate of iodized salt was 94.07％,and the edible rate of qualified iodized salt was 94.07％.Conclusions The median urine iodine of Mongolian and Han pregnant women was generally at the appro-priate level of iodine,but the risk of iodine deficiency and iodine excess existed in different degrees in Mongolian and Han pregnant women.
