宿州市埇桥区2002年碘缺乏病防治监测结果分析

Analysis of IDD Surveillance in 2002 in Yongqiao of Su Zhou Prefecture

目的 了解碘缺乏病防治工作进展情况。方法 按卫生部监测方案要求 ,随机抽取 5所小学校 2 0 0名 8～ 1 0岁的儿童 ,用触诊法检查甲状腺大小 ;同时 ,采集尿样 1 0 0份和碘盐 4 0 9份 ,分别采用砷铈催化分光光度测定接触法和直接滴定法分析尿碘含量与盐碘含量。结果 儿童甲状腺肿大率触诊法为 2 .5 % ;尿碘中位数 4 6 1 .1 μg/L ,大于 2 0 0 μg/L的占 88% ;平均盐碘浓度 2 7.6 5mg/kg ,碘盐合格率 99.5 %。 结论 监测结果说明我区碘缺乏病防治工作 ,继 2 0 0 0年实现碘缺乏病的阶段性目标后 ,防治成果得以巩固。同时也显示 ,为了有效地控制碘缺乏病 ,应当科学地降低食盐加碘量 。

Objective To understand the current status of iodine deficiency disorders (IDD) in Yongqiao. Methods According to the National surveillance programme of IDD issued by Ministry of Health, we randomly selected 200 children aged 8～10 years old from five primary schools in the area. The thyroid size was assessed by palpation, 100 urine and 409 household salt samples were collected randomly for measuring iodine with As (Ⅲ) –Ce4 + catalylic spectrophotometry and iodometric titration method. Results The overall goiter prevalence of the children aged 8～10 years old was 2.5%(palpation). Median urinary iodine were 461.1μg/L. the iodine content of 88% urinary samples were over 200μg/L .Median iodine concentration of household salt were 27.65 mg/kg, 99.5% iodized salts were qualified. Conclusions The results indicated that following realizing the goal of eliminating IDD in 2000, the achievements of IDD control in the area had been enhanced further. At the same time, in order to control IDD scientifically and effectively, we should still implement iodized salts.
