摘要
目的了解石家庄市学龄期儿童碘营养状况,评价2017—2021年补碘干预效果,为今后石家庄市碘缺乏病防治工作提供依据。方法石家庄市21个县(市、区)每年随机抽取200名8~10岁非寄宿学生,并采集其家中食用盐样、随机尿样分别进行盐碘、尿碘含量监测,对部分学生行甲状腺超声检查记录甲状腺容积。结果2017—2021年共监测儿童家庭盐样20399份,尿样20399份,碘盐覆盖率、碘盐合格率和合格碘盐食用率分别为93.66%(19106/20399)、92.40%(17654/19106)和86.54%(17654/20399)。2017—2021年儿童盐碘中位数为22.00mg/kg,尿碘中位数为187.70μg/L,超声检查甲状腺肿大率为2.06%(157/7620)。结论石家庄市学龄期儿童总体处于碘适宜水平,学生家中食用碘盐总体符合国家推荐标准,但仍有无碘盐及不合格碘盐食用现状,存在碘缺乏风险,需加强市场监管;学龄期儿童甲状腺肿大率不高,但甲状腺肿大仍有发生,需加强常规监测。
Objective To understand the iodine nutrition status of school stage children in Shijiazhuang City,to evaluate the effect of iodine supplementation intervention for from 2017 to 2021,and to provide a basis for control and prevention of iodine deficiency disorders in Shijiazhuang City in the future.Methods A total of 200 non-residential students aged 8 to 10 years old were randomly selected each year from 21 counties(cities and districts)in Shijiazhuang City.Salt samples and random urine samples were collected from their households for the monitoring of salt iodine and urinary iodine content,respectively,and thyroid ultrasound was performed on some of the students to record the thyroid volume.Results A total of 20399 salt samples and 20399 urine samples from children's households were monitored from 2017 to 2021.The coverage rate of iodized salt was 93.66%(19106/20399),the qualified rate of iodized salt was 92.40%(17654/19106),and the consumption rate of qualified iodized salt was 86.54%(17654/20399).The median of salt iodine was 22.0mg/kg,the median urinary iodine concentration was 187.70μg/L,and the rate of goitre was 2.06%(157/7620)by thyroid ultrasound for children from 2017 to 2021.Conclusion School stage children are generally at appropriate iodine levels in Shijiazhuang City.The consumption of iodized salt in students'households generally complies with the national recommended standards,but there are still cases of consumption of non-iodized salt and unqualified iodized salt,which present a risk of iodine deficiency and need to strengthen market supervision.The total goiter rate in school stage children is not high,but goitre still occurred and the routine monitoring should be strengthened.
