目的了解深圳市盐田区8～10岁在校儿童碘营养状况,为科学补碘提供参考依据。方法按“人口比例概率抽样方法”(PPS)抽取深圳市盐田区辖区内5所小学8～10岁儿童作为调查对象,进行家中食用盐碘含量、儿童尿碘含量检测、以及甲状腺肿B超检查。结果共抽查5所学校250份8～10岁儿童家中食用盐,有效样本237份,家庭食用碘盐平均合格率为95.78%(227/237),碘盐覆盖率为98.73%(234/237);共采集8～10岁儿童尿样100份,尿碘中位数为160.59μg/L(25.99～583.91μg/L),其中<100μg/L的占14%,<50μg/L的占4%;用B超法共检查8～10岁儿童100人,检出甲状腺肿大4例(男、女各2例),平均甲状腺肿大率为4%。结论深圳市盐田区8～10岁在校儿童碘营养总体水平处于适宜水平,但仍需加强碘缺乏病知识宣传教育。
Objective To understand the iodine nutrition status of children aged 8 ~ 10 in Yantian District of Shenzhen City, and to provide a reference for scientific supplement of iodine. Methods According to “Probability of Population Probability Sampling Method” (PPS), 5 elementary schools of 8 to 10 years old in Yantian District of Shenzhen were selected as the subjects for the study. The content of iodine in food, the urinary iodine in children and the quantity of goiter B Super inspection. Results A total of 250 edible salt samples were collected from 250 children aged 8 to 10 years at home and 237 valid samples were collected. The average pass rate of iodized salt for domestic use was 95.78% (227/237) and the coverage of iodized salt was 98.73% (234/237) ; A total of 100 urine samples from 8 to 10 years old were collected and the median urinary iodine was 160.59μg / L (25.99-583.91μg / L), of which <100μg / L accounted for 14% and <50μg / L accounted for 4% ; 100 children with 8 to 10 years old were examined by B-mode ultrasonography, 4 cases of goiter were detected (2 males and 2 females), and the average goiter rate was 4%. Conclusion The overall level of iodine nutrition of children aged 8 ~ 10 in Yantian District of Shenzhen City is at an appropriate level, but knowledge of iodine deficiency disorders needs to be strengthened.
