【摘要】 目的 了解碘盐预防后重、中度缺碘病区出生儿童亚临床损伤状况，评估病区儿重亚克汀病患病率。方法 采用ＣＲＴ－Ｃ２、ＪＰＢ、测听仪、拍Ｘ线片、标准度衡具检测７～１４岁儿童智商、精神运动功能、听力、骨龄、身高和体重。结果 重、中度缺碘病区儿童智商均值９６．４，轻度智力落后率５．８％；轻度智力落后儿重精神运动功能障碍率６１．６％，听力威退率４３．７％，骨龄、身高、体重发育落后率分别为１８．３％、１７．６％、1０．２％；综合判定轻度智力落后儿童伴有神经、甲状腺功能障碍者占７７．４％，只表现为轻度智力落后者占2２．６％；定量计算重、中度病区供应碘盐后出生儿童亚克汀病患病率为４．５％，其中重度、中度病区儿童亚克订病患病率分别为５．２％、３．９％。结沦 长期碘盐预防明显提高了缺碘病区儿童智力水平，降低了儿童亚克汀病患病率，但重度病区儿童亚克汀病患病率仍高于中度病区。更多还原

【Abstract】 Objective Observined the state of semi-clinical impairment of chilren who has lived at serious and middle iodine deficiency disorder IDD regions after supplied iodized salt. And evaluated the incidence rate of semicritine a- mong children who lived in IDD regions . Methods To test IQ psychomotor audition boneage weight and height of 7-14 years old children with CRT-C2，JPB，diagnostic audiometer,X-ray，weight and height instrument. Result Mean of IQ is 96.4.The rate of wild intelligence delay is 5.8%.Among the mild intelligence delay children the incidence delay of psychomotor is 61.6%.The descend who has been delay of IQ psychomotor mild intelligence delay is 22.6%(incidence of semi-crition is 4.5% children who were born after supplied iodize salt serious and middle IDD regions.It is 5.2% and 3.9 at serious and middle IDD regions.Conclusion Universal iodized salt enhance intelligence level of children and descend the incidence of semi-critine of children.更多还原
