Delay in language development may be associated with an underlying anatomical, neurosensory, or psychological disorder such as: deafness, cerebral palsy, cleft palate, autism, or mental retardation. A condition called specific developmental language delay may occur in children devoid of any other identifiable disorder or developmental delay. Language delay associated with early onset, severe-to-profound hearing impairment has been well documented. Controversial studies have also appeared in the communicative disorders' literature suggesting that fluctuating conductive hearing loss in early childhood can significantly affect the development of language and related academic skills. Some authors have claimed that these deleterious effects can be irreversible. This study focuses on 3 groups of preschool children, in whom hearing acuity has been documented: One group with recurrent otitis and language delay; a second group with an equally well documented otitis history but without language delay; and a third group with documented language delay in the absence of any known predisposing conditions, including early-onset, recurrent otitis media. Prenatal, birth and developmental histories of the children in each group were compared in detail to identify any factors which may enhance or ameliorate the effects of fluctuating conductive hearing loss on language development. In a population of 1864 children (ages 9-59 months) referred for otolaryngologic and/or communicative evaluation, 480 otherwise normal children (67.6% males; 32.4% females) were found to have a history of early-onset, recurrent otitis media and/or delayed speech and language development on the basis of an extensive evaluation battery. This population was further subdivided into 3 groups (I = otitis-positive/normal language; II = otitis-positive/language delay; and III = otitis-free/language delay). Among the 329 children with positive histories for early otitis media (Groups I & II), a significantly higher percentage of those demonstrating language delay were from homes in the lower socio-economic category. Race and sex showed no significant relationship to language delay among the otitis-positive groups, although males were twice as numerous as females in the over-all study population. Articulation errors on speech measures and borderline delays in other developmental milestones (standing, walking, and toilet training) were also significantly greater in the language-delayed group when compared with otitis-positive children whose language was age-appropriate.(ABSTRACT TRUNCATED AT 400 WORDS)
语言发育迟缓可能与潜在的解剖学、神经感觉或心理障碍有关,如:耳聋、脑瘫、腭裂、自闭症或智力迟钝。一种称为特定发育性语言迟缓的情况可能发生在没有任何其他可识别障碍或发育迟缓的儿童身上。与早发性、重度至极重度听力障碍相关的语言迟缓已有充分记录。关于儿童期波动性传导性听力损失会显著影响语言及相关学术技能发展的争议性研究也出现在交流障碍文献中。一些作者声称这些有害影响可能是不可逆转的。本研究聚焦于三组已记录听力敏锐度的学龄前儿童:一组患有复发性中耳炎且有语言迟缓;第二组有同样明确记录的中耳炎病史但无语言迟缓;第三组有记录的语言迟缓但没有任何已知的易患因素,包括早发性复发性中耳炎。详细比较了每组儿童的产前、出生及发育史,以确定可能增强或减轻波动性传导性听力损失对语言发育影响的任何因素。在1864名因耳鼻喉科和/或交流评估前来就诊的儿童(年龄9 - 59个月)中,经过广泛评估,发现480名其他方面正常的儿童(67.6%为男性;32.4%为女性)有早发性复发性中耳炎病史和/或言语及语言发育迟缓。这一人群进一步细分为三组(I = 中耳炎阳性/语言正常;II = 中耳炎阳性/语言迟缓;III = 无中耳炎/语言迟缓)。在329名有早期中耳炎阳性病史的儿童(I组和II组)中,出现语言迟缓的儿童中来自社会经济地位较低家庭的比例显著更高。种族和性别在中耳炎阳性组中与语言迟缓无显著关系,尽管在总体研究人群中男性数量是女性的两倍。与语言发育正常的中耳炎阳性儿童相比,语言迟缓组在言语测量中的发音错误以及其他发育里程碑(站立、行走和如厕训练)中的临界延迟也显著更多。(摘要截选至400字)
