Newborn hearing screening has been successfully implemented worldwide to improve the detection of hearing loss. However, delayed-onset hearing loss subsequent to newborn hearing screening remains a concern. This study aimed to investigate the prevalence of delayed-onset hearing loss in preschool children who previously passed newborn hearing screening in Hubei Province in mid-south China.
Preschool children were screened by transient evoked otoacoustic emission (TEOAE) for delayed-onset hearing loss. Children referred after the TEOAE screening were assessed audiologically.
Between March 2010 and September 2011, 28 546 preschool children (4.86 ± 1.67 years old), who had passed newborn hearing screening were targeted for screening from four cities in Hubei Province, China.
During the study period, 540 children (1.89%) were referred for audiologic assessment and 22 (0.77/1000) of them had permanent delayed-onset hearing loss, including 8 (0.28/1000) with bilateral moderate hearing loss, 10 (0.35/1000) with mild bilateral hearing loss, 2 (0.07/1000) with unilateral moderate hearing loss, and 2 (0.07/1000) with unilateral mild hearing loss.
Despite the success of newborn hearing screening, the provision of hearing screening in preschool remains essential for identifying delayed-onset hearing loss.
新生儿听力筛查在全球范围内已成功实施，以提高听力损失的检出率。然而，新生儿听力筛查后迟发性听力损失仍然是一个关注点。本研究旨在调查中国中南部湖北省既往通过新生儿听力筛查的学龄前儿童迟发性听力损失的患病率。
通过瞬态诱发耳声发射（TEOAE）对迟发性听力损失进行学龄前儿童筛查。TEOAE 筛查后转诊的儿童进行听力评估。
2010 年 3 月至 2011 年 9 月，来自中国湖北省四个城市的 28546 名（4.86±1.67 岁）既往通过新生儿听力筛查的学龄前儿童被确定为筛查目标。
在研究期间，有 540 名儿童（1.89%）被转诊进行听力评估，其中 22 名（0.77/1000）患有永久性迟发性听力损失，包括 8 名（0.28/1000）双侧中度听力损失，10 名（0.35/1000）双侧轻度听力损失，2 名（0.07/1000）单侧中度听力损失，2 名（0.07/1000）单侧轻度听力损失。
尽管新生儿听力筛查取得了成功，但为了发现迟发性听力损失，仍需在学龄前儿童中提供听力筛查。
