Results Evaluation of Eliminating IDD in Wuhou District in Year 2005

目的查明成都市武侯区近年碘缺乏病(IDD)防治效果及流行现状。方法按5个不同地理方位随机抽取5所小学为监测点,采用触诊法检查8～10岁儿童甲状腺;采用"砷-铈催化分光光度法"(WS/T 107-1999)测定尿碘;采用GB/T13025.7-1999)中仲裁法测定盐碘。在每个监测点内随机抽取五年级学生、家庭主妇,进行IDD知识测试。结果检查儿童甲状腺639人,检出Ⅰ度肿大41人,Ⅱ度肿大1人,儿童甲肿率5.26%;采尿样252份,尿碘中位数159.8μg/L,≥100μg/L的占70.24%,≤50μg/L的占11.90%,≤20μg/L的占3.97%;碘盐合格率平均为95.67%;IDD知识测试及格率平均为90.00%。结论4项消除IDD监测指标,均达到IDD消除标准。

Objective To know the preventive effect and the present prevalent situation of IDD in Wuhou district, Chengdu city. Methods 5 primary schools were selected by using random sampling methods; thyroid gland of pupils aged from 8 to 10 were examined by palpation; salt samples were evaluated according to GB/ T13025.7-1999; urinary iodine samples were evaluated by as-ce catalysis spectrophotometry; children and housewives were asked about IDD related knowledge. Results 639 thyriod gland of pupils were examined. The Results showed that the goitre rate was 5.26% ; the median level of urinary iodine was 159.80μg/L, while the levels of urinary iodine above 100μg/L and below 50μg/L accounted for 70.24% and 11. 90% respectively. The qualified rate of iodized salt was 95.67% , and the pass rate of test of IDD related knowledge was 90. 00%.
