2007年广西碘缺乏病高危地区重点调查结果分析

Survey on Iodine Deficiency Disorders in high risk areas in Guangxi,2007

目的了解广西碘缺乏病重点地区新发克汀病病人情况和5个高危县防治工作现况。方法对34个重点县进行新发克汀病病人搜索,并对5个高危县进行盐碘、尿碘、甲状腺肿大率、智商水平、健康教育等指标监测。结果搜索、诊断7例新发克汀病病人;检查8～10岁儿童3 007人,触诊法检测甲状腺肿大率平均为6.45%,B超法检测甲状腺肿大率平均为12.50%;儿童尿碘中位数为262.30μg/L,孕妇和哺乳期妇女尿碘中位数为233.20μg/L;儿童智商平均水平为87.64,智商<69的占16.5%,智商>130的占3.6%;680份居民食盐半定量检测,其含碘率为96.03%;家庭主妇碘缺乏病防治知识知晓率为45.88%。结论广西存在散发克汀病病例,碘缺乏病防治工作在巩固成绩的基础上,重点抓好薄弱地区和薄弱环节的工作。

Objectives To unerstand the prevalence of cretinism in high endemic areas of Iodine Deficiency Disorders （IDD） and current progress on the disease control in 5 high risk counties in Guangxi. Methods Stratified sampling was used to screen new eases of cretinism in 34 high endemic counties. Examination and determination of indicators including salt and urinary iodine, goiter rate, intelligence quotient （IQ） and health education were conducted in 5 high risk counties. Results 7 eases of eretinism were identifed. In 3 007 children aged 8 to 10 years, the prevalance of goiter measured by palpation was 6.45% and by ultrasound 12.50%. The median urinary iodine was 262. 30 μg/L for children and 233. 20 μg/L for pregnant and lactating women. The children＇s IQ averaged 87.64, and the proportion with IQ below 69 was 16.5% and above 130 was 3.6%. 680 family salt samples by semi - quantitative analysis showed a household coverage of 96.03% by iodized salt. The awareness rate for knowledge on IDD was 45.88% among housewives. Conclusion Sporadic cretinism exists in Guangxi. In addition to sustaining current achievements, we need to redirect and focus control strategies to the regions yet to reach criteria.
