研究儿童尿碘水平与听力改变的关系。抽取春城小学１５０名８～１０岁学童进行尿碘测定，并将其中低尿碘组和正常尿碘各３０名进行双耳纯音气导听力测定。尿碘中位数为１７１４μｇ／Ｌ，低尿碘组平均听阈显著高于正常尿碘对照组（１９７５±６９７ｄＢＶＳ１２４７±４６６ｄＢ，Ｐ＜００１）。低尿碘学童往往有听力障碍，且主要是在高频区 To study the relationship between urinary iodine levels and hearing changes in children. Urine iodine was determined in 150 students of 8 ~ 10 years old in Chuncheng Primary School and 30 patients with low urine iodine group and 30 normal urinary iodine were measured with binaural pure tone guided hearing. The median urinary iodine was 1714 μg / L. The average hearing threshold of low-urinary iodine group was significantly higher than that of normal urinary iodine control group (1975 ± 697 dBVS1247 ± 4.66 dB, P <001). Low-urinary iodine school children often have hearing disabilities, and mainly in the high-frequency area
