摘要
目的了解扬州市2020年(8~10)周岁学龄儿童和孕妇两类人群碘营养状况,为今后碘缺乏病防治工作提供科学依据。方法2020年在6个县(市、区)按东、西、南、北、中划分为5个抽样方位,每个方位随机抽取1个乡镇/街道,每个乡镇/街道随机抽取20名孕妇和1所小学的40名(8~10)周岁非寄宿学生。监测(8~10)岁学龄儿童尿碘、盐碘含量及甲状腺肿大情况;孕妇尿碘、盐碘含量。结果共监测1200名(8~10)岁学龄儿童及600名孕妇;盐碘均数为(23.85±4.14)mg/kg,碘盐覆盖率为99.06%,盐碘合格率为97.03%,合格碘盐食用率为96.11%。(8~10)岁学龄儿童尿碘中位数为224.8μg/L,孕妇尿碘中位数为189.0μg/L。在广陵、江都和仪征3个县区开展(8~10)岁学龄儿童甲状腺容积检测,甲状腺容积中位数为2.15 mL,甲状腺肿大率为1.70%。结论2020年扬州市(8~10)岁学龄儿童和孕妇碘营养总体适宜,其中部分人群碘营养水平低于适宜量,孕妇这一比例尤为显著,应当加强宣传,进一步落实防控措施。
Objective To investigate the iodine nutritional status of children at school(aged 8-10 years) and pregnant women in Yangzhou, Jiangsu province, China, 2020, and to provide a scientific basis for future prevention and treatment of iodine deficiency diseases. Methods Twenty pregnant women and 40 non-boarding students(aged 8-10 years) of a primary school were randomly selected from one each from the eastern, western, southern, northern, and central regions of 6 counties(cities or districts) in 2020. Urinary iodine levels, iodine content in edible salt, and goiter status among the children were monitored as well as urinary iodine levels and iodine content in edible salt among the pregnant women. Results A total of 1 200 children(aged 8-10 years) and 600 pregnant women was investigated. The mean iodine content in edible salt was(23.85±4.14) mg/kg. The coverage rate of iodized salt was 99.06%. The qualification rate of salt iodine content was 97.03%, and the consumption rate of qualified iodized salt was 96.11%. The median urinary iodine level was 224.8 μg/L in the children and 189.0 μg/L in the pregnant women. The median thyroid volume was 2.15 mL, and the goiter rate was 1.70%, according to the thyroid volume data of children aged 8-10 years in Guangling District, Jiangdu District, and Yizheng City. Conclusion The iodine nutritional status of children aged 8-10 years and pregnant women is generally good in Yangzhou, 2020. However, a certain proportion of the schoolchildren and pregnant women are still below the appropriate iodine nutritional level, especially in pregnant women. Therefore, it should be carried out further publicity and preventive measures.
