摘要
目的了解浙江省玉环县8~10岁儿童尿碘水平以及食用盐碘含量状况。方法采用现况调查设计,2012年在浙江省玉环县针对性抽取一所小学,以分层整群抽样的方法抽取8~10岁儿童450人进行免费体检,同时收集晨尿及家庭正在食用的盐,完成晨尿尿碘水平测定及食用盐碘含量测定。结果共检测儿童尿样449份,尿碘中位数为114.0μg/L,尿碘含量〈50μg/L、〈100μg/L、≥300μg/L分别占4.4%、37.9%、2.7%。同时,检测盐碘447份,盐碘中位数为0.0mg/kg,碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为27.3%、92.6%、25.3%。食用非碘盐儿童尿碘中住数低于食用碘盐儿童尿碘中位数,其差异有统计学意义(Z=3.47,P=0.001)。结论浙江省玉环县8—10岁儿童碘营养状况总体上是适宜和安全的,但是碘摄入不足的风险不容忽视。
Objective To understand the level of urinary iodine and iodine content of salt among school children aged 8 to 10 years in Yuhuan County, Zhejiang Province. Methods A cross-sectional study was conducted in a primary school of Yuhuan County purposely selected in 2012. Totally, 450 children aged 8 to 10 years were involved by the cluster-stratified sampling. All subjects received a free physical examination and morning urine and salt using in the household were collected. Urinary iodine and the iodine content of salt the children were tested. Results Totally, 449 of 450 children provided the morning urine enough to be tested. The median of children's urinary iodine was 114. 0 μg/L, and the proportions of them with the urinal iodine 〈 50 μg/L, 〈 100μg/L and ≥300 μg/L were 4. 4% , 37.9% and 2. 7% , respectively. Among 447 salt samples collected, the median of iodine content was 0.0 mg/kg. The coverage rate of iodized salt was 27.3% , the qualified rate of iodized salt was 92.6% , and the intake rate of qualified iodized salt was25.3%. The median of urinary iodine of children with iodized salt was significantly higher than that nutritional aged 8-10 of those without iodized salt ( Z = 3.47, P = 0. 001 ). Conclusion Currentnutritional status of iodine is overall proper and safety in the population of school children aged 8-10 years old in Yuhuan County.
