Outcome analysis on iodine deficiency disorders surveillance in Xinzhou during 2001-2005

目的了解山西省忻州市实现消除碘缺乏病(IDD)阶段目标后,IDD病情的消长趋势,干预措施落实情况和防治效果。方法根据《全国碘缺乏病监测方案》中的监测指标,采用重点人群碘营养状况的一次性调查方法,2001-2005年在全市14个县(市、区)进行抽样监测,包括儿童甲状腺肿大率(简称甲肿率)、尿碘水平、居民盐碘、IDD健康教育知识及儿童智商水平。结果5年儿童甲肿率在5.38%～7.97%;儿童尿碘中位数在225.48～334.54μg/L;居民合格碘盐食用率均>90%;IDD健康教育知识问卷调查,5年级学生平均得分60.2分,及格率55.3%,家庭主妇平均得分83.2分,及格率92.7%;儿童智商为中等水平。结论忻州市8～10岁儿童甲肿率、尿碘水平和居民合格碘盐食用率3项指标继续保持在消除IDD阶段目标水平;IDD健康教育宣传不到位,知识普及率呈下滑趋势:儿童智商水平经全民食盐加碘后得以提高。

Objective To investigate the prevailing tendency of iodine deficiency disorders（IDD） and the fulfillment of prevention and control of IDD. Methods Using the indices stipulated in ＂The National Project of Surveillance on IDD＂ iodine nutrition situation was investigated among people in the endemic area. Urinary iodine, child goiter rate, iodized salt coverage, health education on I DD and children＇s intelligence quotien （IQ） level were surveyed using sampling method in 14 counties of the city in each year from 2001 to 2005. Results During 2001 to 2005, goiter rate of children ranged from 5.38% to 7.97%. The averaged urine iodine flucuated in the range of 225.48 μg/L and 334.54 μg/L. Iodized salt covered more than 90% of the residents. IDD health knowledge questionaire revealed that students in Grade 5 and housewives respectively got an anveraged mark of 60.2 and 83.2, with a pualified rate of 55.3% and 92.7% respectively. Children＇s IQ was in moderate level. Conclusions Goiter rate of children （aged from 8 - 10）, the iodine value in urine, and the coverage of iodized salt in residents are in the stage of aiming at eliminating IDD. The propaganda of health knowledge on IDD is not effective leading to the awareness of IDD to decrease. Children＇s IQ level has been improved after universal use of iodized salt.
