本研究调查了 8 岁时患有唐氏综合症的儿童听力损失的患病率。所有儿童均在挪威公立医院的耳鼻喉科接受了检查，研究人群包括 2002 年在挪威出生的患有唐氏综合症的儿童。听力损失被定义为听力最好的耳朵的纯音气导平均降低超过 25 dB HL。选择一项基于临床和听力学人群的横断面研究作为研究设计。17/49 名儿童 (35%) 的最佳听力耳朵听力损失超过 25 dB HL。 13 名儿童（26%）患有轻度听力损失，3 名儿童（6%）患有中度听力损失，1 名儿童（2%）患有重度听力损失。 8 名儿童（16%）存在传导性听力损失，9 名儿童（18%）存在感觉神经性听力损失，3 名儿童存在混合性听力损失。男孩和女孩的平均听力水平分别为 30.0 dB HL (SD 15.7) 和 25.5 dB HL (SD13.7)，差异不显着 (p = 0.139)。 总之，这项研究表明，传导性听力损失和感音神经性听力损失在 8 岁的唐氏综合症儿童中仍然很常见，多达三分之二的儿童可能有双侧听力损失。研究人群的听力损失诊断不足，因此我们的研究结果强调了对这组儿童在整个童年时期进行持续听力学随访的重要性。 (C) 2013 Elsevier Ltd. 保留所有权利。
This study examines the prevalence of hearing loss in children with Down syndrome at the age of 8. All children were examined in the ENT-departments of public hospitals in Norway and the study population consisted of children born in Norway in 2002 with Down syndrome. Hearing loss was defined as pure-tone air-conduction reduction by on average more than 25 dB HL in the best hearing ear. A cross sectional clinical and audiological population based study was chosen as study design.Hearing loss more than 25 dB HL in the best hearing ear was found in 17/49 children (35%). Mild hearing loss was found in 13 children (26%), moderate in 3 (6%) children and severe hearing loss in 1 child (2%). Conductive hearing loss was found in 8 children (16%), 9 children (18%) had a sensory-neural hearing loss, and mixed hearing loss was found in 3 children. Mean hearing level among boys and girls were 30.0 dB HL (SD 15.7) and 25.5 dB HL (SD13.7) respectively, a non-significant difference (p = 0.139).In conclusion this study indicates that both conductive and sensorineural hearing loss, is still common in children with Down syndrome children at the age of eight and as much as two thirds of the children may have a bilateral impairment. The study population was under diagnosed in terms of hearing loss and thus our findings underline the importance of continuous audiological follow up of this group of children throughout childhood.
