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.
