The Iodine Nutritional Status of Children Aged 8 to 10 Years Old in Sichuan Province in 2018

目的了解2018年四川省8~10岁儿童碘营养状况。方法 2018年在四川省选择21个县(市、区),在每个县(市、区)按东、西、南、北、中5个方位各随机抽取1个乡(镇、街道),在每个乡的中心小学用B超法检查40名8~10岁儿童的甲状腺并采集尿样及家中食用盐样,检测尿碘及盐碘含量。结果共调查8~10岁儿童4 221名,甲状腺容积中位数为2.80 ml,甲肿率为1.63%,甲状腺结节检出率为4.93%;碘盐覆盖率为99.55%,合格碘盐食用率为95.45%;尿碘中位数为197.90μg/L。结论 2018年四川省以食盐加碘为主的碘缺乏病综合防治措施成效显著,8~10岁儿童碘营养处于适宜水平。

Objective To understand the current iodine nutritional status of children aged 8 to 10 years old in Sichuan. Methods A town was randomly chosen from each of 21 counties according to the east,west,south,north and middle locations. The thyroid of 40 children aged 8~10 years old were examined by B ultrasound in township elementary school,as well as urinary iodine was also detected, and the salt iodine content was determined which was sampled from each child’s household. Results About 4 221 children aged 8-10 years old were tested, total goiter rate of children aging 8~10 years old was 1.63% by B ultrasound,the prevalence of thyroid nodule were identified as 4.93%. The median of thyroid volume was 2.80 ml;the coverage rate of iodized-salt was 99.55%, the qualified iodized salt coverage rate was 95.45%;the median urinary iodine was197.90μg/L. Conclusion The comprehensive prevention and control measures of Iodine Deficiency Disorders based on salt iodization in Sichuan province are effective. The iodine nutrition level of children aged 8~10 years old was optimal.
