摘要
目的了解河南省实施食盐加碘新标准5年后8~10岁儿童碘营养水平,为科学调整干预策略提供依据。方法2017年,按照《河南省碘缺乏病监测方案》,以8~10岁儿童(男女各半)为研究对象,在河南省的156个非高碘县(市、区)和高碘县(市、区)所辖的非高碘地区,采集家中食用盐盐样,检测盐碘含量;在113个县(市、区),采集即时尿样,检测尿碘含量;在67个县(市、区),检查甲状腺容积。盐碘检测采用直接滴定法,川盐及其他强化食用盐检测采用仲裁法,尿碘检测采用砷铈催化分光光度法,甲状腺容积检查采用B超法。结果2017年,共检测8~10岁儿童家中盐样31174份,盐碘中位数为25.8mg/kg,碘盐覆盖率为95.0%(29613/31174),合格碘盐食用率为85.6%(26673/31174)。检测儿童尿样22442份,尿碘中位数为208.0μg/L。对13439名儿童进行甲状腺容积检测,甲状腺肿大率为1.5%(196/13439)。结论盐碘新标准实施后,河南省8~10岁儿童碘营养水平处于基本适宜状态,但是合格碘盐食用率较低,应长期坚持食盐加碘为主的综合防治措施并加强碘缺乏病防治知识的健康教育。
Objective To investigate the iodine nutritional status among children aged 8-10 years old in Henan Province after five years of implementation of new standard iodized salt, and to provide evidence for scientific adjustment of control strategy. Methods In 2017, according to "Henan Surveillance Program on Iodine Deficiency Disorders", children aged 8-10 years old (half males and half females) were chosen as research targets. In non-high iodine areas of 156 non-high iodine counties (cities, districts) and high iodine counties (cities, districts) in Henan Province, household salt samples were collected;in 113 counties (cities, districts), urine samples were collected;in 67 counties (cities, districts), thyroid volume was measured. Salt iodine was tested by direction titration, the salt samples from Sichuan and other enhanced salt samples were tested by the arbitration method;urinary iodine was tested by arsenic cerium catalytic spectrophometry;thyroid volume was measured by ultrasound method. Results In 2017, totally 31 174 household salt samples of 8-10 years old children were collected and tested, the median of salt iodine was 25.8 mg/kg;the coverage rate of iodized salt was 95.0% (29 613/31 174) and the consumption rate of qualified iodized salt was 85.6% (26 673/31 174). Totally 22 442 urine samples were collected and the median of urinary iodine content was 208.0 μg/L. Totally 13 439 school children were examined thyroid volume and the goiter rate was 1.5% (196/13 439). Conclusions After the promotion of new standard iodized salt, the iodine nutritional status of children aged 8-10 years old in Henan Province is appropriate. However, the consumption rate of qualified iodized salt is lower, so the universal salt iodization prevention and control strategies should be performed for a long time. At the same time, health education of iodine deficiency knowledge should be strengthened.
