目的通过对2013-2014年四川省双流县8~10岁儿童的碘营养状况监测结果进行分析,为指导碘缺乏病防治工作提供依据。方法进行儿童甲状腺B超检查,尿碘水平检测以及调查每日通过食盐摄入的碘含量,对结果进行分析。结果 2013、2014年8~10岁儿童甲状腺肿大率分别为2.14%、2.75%,校正甲状腺肿大率分别为2.34%、3.05%,均小于5%;每日通过食盐摄入的碘含量为234.9 g/d;2013、2014年尿碘中位数分别为180.7μg/L、204.7μg/L,中位数差异无统计学意义(P>0.05),小于50μg/L的比例分别为0%、6%,小于100μg/L的为0%、18%。结论 2013-2014年双流县8~10岁儿童的碘营养处于适宜水平。
Objective To analyze the monitoring results of iodine nutrition status of children aged 8 ~ 10 years in Shuangliu County, Sichuan Province from 2013 to 2014 so as to provide basis for the prevention and control of iodine deficiency disorders. Methods Children with thyroid B-ultrasound, urinary iodine levels and iodine intake daily salt intake survey, the results were analyzed. Results The goiter rates of children aged 8-10 years old in 2013 and 2014 were 2.14% and 2.75%, respectively. The corrected goiter rates were 2.34% and 3.05% respectively, both of which were less than 5%. The daily iodine intake of salt intake was 234.9 g / d respectively. The median of urinary iodine in 2013 and 2014 were 180.7μg / L and 204.7μg / L, respectively. There was no significant difference in the median of urinary iodine between 2013 and 2014 (P> 0.05) , 6%, less than 100μg / L of 0%, 18%. Conclusion The iodine nutrition of children aged 8 ~ 10 years in Shuangliu County was at a suitable level during 2013-2014.
