摘　　要：为研究儿童尿碘水平与听力和语言智商的关系。随机抽样昆明春城小学１５０名８～１０岁学童收集其尿液进行尿碘测定。并将其中６０名学童分为两组（低尿碘组和正常尿碘对照组，每组各３０名），进行双耳纯音气导听力测定，用韦克斯勒学龄儿童智力测验量表（ＷＩＳＣ－ＣＲ）测试语言智商。结果表明，尿碘中位数为１７１．４μｇ／Ｌ，尿碘值在１００μｇ／Ｌ以下的共４０例，占２６．７％。低尿碘组学童平均听阈显著高于正常尿碘对照组（１９．７５±６．９７ｖｓ１２．４７±４．６６ｄＢ，Ｐ＜０．０１）；低尿碘组平均语言智商显著低于正常尿碘对照组（１１１．８７±１５．０７ｖｓ１２６．０３±１２．００，Ｐ＜０．０１）；低尿碘听力异常学童平均语言智商显著低于低尿碘听力正常学童（１０１．２９±８．３７ｖｓ１２４．７３±１０．８７，Ｐ＜０．０１）。低尿碘男女学童间平均听力和平均语言智商比较均无显著差异（２０．０３±７．５９ｖｓ１９．１６±５．３８，Ｐ＞０．０５；１１５．７５±１７．３８ｖｓ１１５．３３±１３．０８，Ｐ＞０．０５）。表明低尿碘学童有听力和语言障碍；低尿碘学童伴听力异常者都存在语言智力障碍，提示缺碘对儿童听力和语言智力的损害是平行发展。低尿碘?To study the relationship among the urinary iodine level,hearing and the verbal IQ of children.We also measured the pure hearing of double ears (air-conduction) and the verbal intelligence quotient (IQ) with the WISC-CR.The subjects were divided into 2 groups,the first group was 30 children with the low urinary iodine level,the second group was 30 children with the normal urinary iodine level as the control.The average hearing and the average verbal IQ of the low urinaty iodine group were significantly lower than those of the control group,respectively (1975±697vs12.47±4.66dB,P<001;11187±1507vs126.03±12.00,P<001).There were hearing loss and decreased verbal IQ in the school children.Both the hearing loss and the decreased verbal IQ might occur in the children with low urinary iodine.It suggested that the mild impairment of audiometry and verbal intellectual development in relation to iodine deficiency happende in the meantime.
