To systematically review the current literature to describe the speech, language, and literacy skills of children with mild to moderate hearing loss (MMHL).
Systematic searching of seven online databases identified 13 eligible studies examining speech, language, and literacy outcomes for children with MMHL. Studies were rated for quality. Findings were reported via narrative synthesis.
Many studies reported no significant differences between children with MMHL and hearing peers on speech, language, and literacy measures. Studies that did report significant differences reported that children with MMHL performed significantly more poorly than hearing peers in speech production, receptive morphology, following directions, recalling sentences, expressive morphology, and word and non-word reading.
Due to the heterogeneity in participant characteristics, moderating factors reported, and measures used, clear patterns in the outcomes were difficult to find. Further research into speech, language and literacy outcomes for children with MMHL from early childhood to adolescence (longitudinal studies) are required to describe possible trajectories for children with MMHL including how moderating factors (such as age of hearing aid fitting, duration of use, and access to early intervention) may be contributing to these trajectories.
系统回顾当前文献，以描述轻中度听力损失（MMHL）儿童的言语、语言和读写能力。
对七个在线数据库进行系统检索，确定了13项符合条件的研究，这些研究考察了MMHL儿童的言语、语言和读写结果。对研究进行质量评级。研究结果通过叙述性综合报告。
许多研究报告称，MMHL儿童与听力正常的同龄人在言语、语言和读写测量方面没有显著差异。确实报告有显著差异的研究表明，MMHL儿童在言语表达、接受性词法、听从指令、回忆句子、表达性词法以及单词和非单词阅读方面的表现明显比听力正常的同龄人差。
由于参与者特征、报告的调节因素和使用的测量方法存在异质性，难以找到结果中的明确模式。需要对从幼儿期到青少年期的MMHL儿童的言语、语言和读写结果进行进一步研究（纵向研究），以描述MMHL儿童可能的发展轨迹，包括调节因素（如助听器佩戴年龄、使用时长和获得早期干预的机会）可能如何影响这些轨迹。
