摘要
目的了解陕西省儿童和孕妇碘营养现状,为防治碘缺乏病提供科学依据。方法2019年,在陕西省下辖的110个县(市、区),每个县(市、区)按东、西、南、北、中划分5个抽样片区,每个片区抽取1个乡镇或街道(以下简称乡),每个乡抽取1所小学,每所小学抽取8~10岁非寄宿学生42人(年龄、性别均衡),同时每个抽中乡抽取21名孕妇作为调查对象,检测家庭食用盐碘含量和随意1次尿样碘含量。此外,对39个县(市、区)的抽中儿童进行甲状腺B超检查。结果共检测23101名8~10岁儿童家庭食用盐盐样和尿样,家庭食用盐碘含量为(24.07±3.71)mg/kg,合格碘盐食用率为97.55%(22536/23101),尿碘中位数为211.68μg/L。共检查8191名儿童甲状腺,甲状腺肿大率为1.50%(123/8191)。共检测11555名孕妇家庭食用盐盐样和尿样,家庭食用盐碘含量为(24.05±3.66)mg/kg,合格碘盐食用率为97.57%(11274/11555),尿碘中位数为182.74μg/L。结论2019年陕西省儿童碘营养处于超适宜水平,孕妇碘营养为适宜水平,食用盐碘含量可进行微调,但建议对孕妇人群供应专用碘盐。
Objective This study aims to provide scientific evidence for prevention and treatment of iodine deficiency disorders through monitoring the iodine nutrition status of children and pregnant women in Shaanxi Province.Methods Totally 110 counties(cities,districts)in Shaanxi Province in 2019 were surveyed.Each of the counties(cities,districts)was further divided into five sampled regions along five different geographic directions:east,west,south,north and middle.From each region,one town was selected and then one primary school was selected from each town.Finally,there were a total of 42 non-boarding students aged 8-10 years old(age and gender balanced)selected from each school,who would be tested household salt iodine's level and urinary iodine's level.Also,we did the same test for 21 pregnant women who were selected from each town randomly.Additionally,we examined the children's thyroid by B-scan ultrasonograph in 39 counties(cities,districts).Results A total of 23101 salt and urine samples were collected from children aged 8-10 years old,the average of salt iodine content of the children'family was(24.07±3.71)mg/kg;the consumption rate of qualified iodized salt was 97.55%(22536/23101);the median urinary iodine was 211.68μg/L;and the thyroid goiter rate(TGR)was 1.50%(123/8191).A total of 11555 salt and urine samples from pregnant women were collected,the salt iodine content was(24.05±3.66)mg/kg;and the consumption rate of qualified iodized salt was 97.57%(11274/11555);the median urinary iodine was 182.74μg/L.Conclusions In 2019,the iodine nutrition of children in Shaanxi Province is in the super appropriate level,and the iodine nutrition of pregnant women is appropriate.The iodine content of edible salt can be adjusted.It is suggested that pregnant women should be supplied special iodized salt.
