摘要
目的 了解2020—2024年陕西省西安市莲湖区重点人群碘营养状况,为科学调整碘缺乏病防治策略提供依据。方法 每年在全区范围内监测8~10岁儿童及孕妇盐碘、尿碘水平,同时现场检查儿童甲状腺肿大情况。结果 2020—2024年共采集8~10岁儿童及孕妇家庭食用盐盐样1 575份,盐碘中位数为25.20 mg/kg,合格碘盐食用率为93.46%,碘盐覆盖率为99.43%。共监测儿童1 050名,儿童尿碘中位数为205.57μg/L;儿童甲状腺肿大率为1.43%。共采集孕妇尿样525份,尿碘中位数为180.00μg/L。结论 2020—2024年莲湖区儿童和孕妇整体处于碘适宜水平,但仍有相当比例的儿童存在碘过量风险,孕妇存在碘缺乏风险,今后应继续做好重点人群监测工作并积极开展科学补碘教育。
Objective To investigate the iodine nutrition status of key populations in Lianhu District,Xi'an City,Shaanxi Province from 2020 to 2024,and provide a basis for scientifically adjusting iodine deficiency disorders(IDD)prevention and control strategies.Methods The monitoring of salt iodine and urinary iodine levels was conducted for children aged 8 to 10 years and pregnant women across the entire district.Concurrently,on-site examinations for childhood goiter were performed.Results From 2020 to 2024,a total of 1575 samples of household edible salt were collected from children aged 8 to 10 years and pregnant women,the median of salt iodine was 25.20 mg/kg,the qualified iodized salt consumption rate was 93.46%,the iodized salt coverage rate was 99.43%.A total of 1050 children were investigated,the median urinary iodine(MUI)of children was 205.57μg/L,and the children's goiter rate was 1.43%.A total of 525 urine samples were collected from pregnant women,the MUI of pregnant women was 180.00μg/L.Conclusion From 2020 to 2024,children aged 8 to 10 and pregnant women in Lianhu District were at an appropriate level of iodine,but a considerable proportion of children were at risk of iodine excess,and many pregnant women were in a state of iodine deficiency.In the future,the monitoring of key populations should be continued,and scientific iodine supplementation education carried out.
