2008年河北省碘缺乏病防治效果调查分析

目的 掌握河北省防治碘缺乏病的效果,及时发现碘缺乏病防治中存在的问题,为防治工作提供科学依据.方法 2008年,根据碘缺乏病的历史病情,在河北省11个市,每个市选择2～3个县(市、区),每县(市、区)选择1个历史上碘缺乏病较重的乡;在每个乡选择2～3所村小学共计抽取100名8～10岁在校学生,采用触诊法检查其甲状腺肿大情况并测定其尿含碘量,同时采集40名学生家中食用盐测定含碘量,在所选取的小学所在村选取50名18～40岁育龄妇女测定其尿含碘量.检测当地饮用水含碘量.结果 共23个县(市、区)采集水样92份,水碘范围为0.21～61.25μg/L.甲状腺触诊检查8～10岁学生2410名,甲状腺肿大率为2.4%(58/2410).检测盐样1312份,碘盐覆盖率为92.4%(1212/1312),碘盐合格率为96.4%(1169/1212),合格碘盐食用率为89.1%(1169/1312),有30.4%(7/23)的县(市、区)合格碘盐食用率低于90%.共采集2191份8～10岁儿童尿样和1000份18～40岁育龄妇女尿样,尿碘中位数分别是185.2μg/L和201.3μg/L.结论 河北省儿童和育龄妇女碘营养总体上处于适宜水平,但武安市可能碘营养不足.在低碘盐覆盖率地区还存在孕妇和哺乳妇女碘营养不足的可能,对这些地区应该加强监测,必要时对他们进行适时补碘措施.

Investigation on the effect of prevention and care of iodine deficiency disorders in Hebei province in 2008

Objective To investigate the current situation of the prevention and control of iodine deficiency disorders(IDD)in the Hebei province for 2008 to find problems and provide a basis for the prevention and control of IDD.Methods According to the history of IDD,2-3 counties were chosen each city of Hebei.A town with Serious IDD historically was selected in each county with 2-3 primary schools investigated subsequently.One hundred students aged 8-10 years old were chosen to examine their thyroid size and to collect urine samples for iodine content.Forty salt samples chosen from the above students and 50 urine samples of fertile women.18-40 years old,living near the above school were tested for iodine content.Water iodine was detected.Results A total of 92 water samples were collected in 23 towns.The water iodine ranged from 0.21 to 61.25μg/L.AU 2410 children had their thyroids checked by the palpation method and the goiter rate was 2.4%.1312 salt samples were collected.Iodized salt accounted for 92.4%(1212/1312),of which,96.4%(1169/1212)were qualified and the consuming rate of qualified iodized salt was 89.1%(1169/1312).30.4%(7/23)of counties consumed qualified iodized salt.accounting for 90%of the total.A total of 2191 urine samples of children and 1000 urine samples of fertile women were detected to be 185.2 μg/L and 201.3 μg/L,respectively.Conclusions The iodine nutrition of two groups in Hebei province is appropriate.However,if taken separately,two groups in Wuan Rre probably at the level of defective nutrition.We presume from the results that the possibility of iodine deficiency in pregnant and nursing women is existent in areas with low coverage rate of iodized salt.Surveillance should be strengthened in these areas and the measure of replenishing iodine should be taken for pregnant and nursing women when necessary.
