Abstract:
Objective:To study the iodine nutrition status of children in non-high water iodine areas of Inner Mongolia Autonomous Region, analyze the monitoring results of iodine deficiency disorders, so as to provide a basis for further guidance on scientific iodine supplementation for children in Inner Mongolia Autonomous Region.Methods:According to the requirements of the National IDD Monitoring Program and the IDD Monitoring Program of Inner Mongolia in 2021, cluster sampling method was used to select non boarding children aged 8 - 10 from 104 counties (cities, districts) in 12 cities within the jurisdiction of Inner Mongolia Autonomous Region. Random urine samples and household salt samples were collected to detect iodine content. At the same time, 1/3 of the selected children were selected for thyroid B-ultrasound examination to measure thyroid volume.Results:In 2021, a total of 19 968 children aged 8 - 10 in non-high water iodine areas of Inner Mongolia were monitored, and 19 968 urine samples were collected, with a median urine iodine of 199.23 μg/L. There was a statistically significant difference in the frequency distribution of urinary iodine in different cities (χ 2 = 839.51, P < 0.001). The median iodine content of children's household edible salt was 22.64 mg/kg, and the coverage rate of iodized salt, qualified iodized salt coverage rate, and non-iodized salt rate in the entire region was 99.05% (19 778/19 968), 94.98% (18 785/19 778), 94.08% (18 785/19 968) and 0.95% (190/19 968), respectively. Thyroid B-ultrasound were performed in 6553 children, the goiter rate was 1.30% (85/6 553), and there were statistically significant differences in goiter rates among children of different ages and cities (χ 2 = 87.09, P < 0.001; χ 2 = 10.40, P = 0.006) . Conclusions:In 2021, the iodine nutrition of children aged 8 - 10 in non-high water iodine areas of Inner Mongolia is at an appropriate level. However, in the future we should continue to adhere to the monitoring of iodine deficiency disorders, strengthen health education on iodine deficiency disorders, consolidate existing achievements in iodine deficiency disease prevention and control, and achieve the goal of continuous elimination of iodine deficiency disorders.
