其目的是：（1）提供31、43和61月龄时的单词识别阈值（WRT）;（2）研究随时间的发育变化;（3）研究OME和WRT之间的关系;（4）研究WRT和听力阈值之间的关系。作为ALSPAC研究的一部分，对大约1000名儿童进行了纵向测试，使用了安静条件下单词识别的自适应措施。31、43和61个月时的平均WRT分别为28、23和23 dB（A）。正常的听觉发育与年龄31至61个月的WRT平均改善5 dB相关。当OME出现在一只和两只耳朵中时，WRT分别平均增加5 dB和15 dB。因此，单侧和双侧OME都对言语听力产生不利影响。此外，早期和“持续性”OME与更大的残疾有关。然而，到61个月时，既往OME状态并不显著。据我们所知，这是最大的纵向研究报告WRT在学龄前儿童与不同的中耳状态。
The aims were to: (1) provide word recognition thresholds (WRTs) at 31, 43, and 61 months of age; (2) investigate developmental changes over time; (3) investigate the relationship between OME and WRT, and (4) investigate the relationship between WRT and hearing thresholds. Around 1000 children were tested longitudinally as part of the ALSPAC study, using an adaptive measure of word recognition in quiet. Mean WRTs were 28, 23, and 23 dB (A) at 31, 43, and 61 months, respectively. Normal auditory development is associated with a mean improvement in WRT of 5 dB between age 31 and 61 months. There was a mean increase in WRT of 5 dB and 15 dB when OME was present in one and two ears, respectively. Thus, both unilateral and bilateral OME results in a detrimental effect on hearing ability for speech. Additionally, early and ‘persistent’ OME is associated with greater disability. However by 61 months, previous OME status was not significant. To our knowledge, this is the largest longitudinal study reporting WRT in preschool children with different middle ear status.
