This article describes the major findings of the Longitudinal Outcomes of Children with Hearing Impairment (LOCHI) study.
A population-based prospective cohort study; with randomized controlled trials of hearing aid prescription and non-linear frequency compression.
451 children in New South Wales, Victoria and Southern Queensland.
Significant predictors of language outcomes at 3 years of age included severity of hearing loss, gender, presence of additional disabilities, maternal education, and age at cochlear implantation. Although prescription did not have a significant effect on outcomes, its influence on loudness and hearing aid safety has implications for management. After controlling for a range of predictor variables, nonlinear frequency compression did not have a significant effect on outcomes. For the same hearing sensitivity, the presence of auditory neuropathy did not have a significant effect on outcomes.
These findings form the basis for evidence-based guidelines for management of children with hearing loss.
本文描述了听力障碍儿童纵向结局（LOCHI）研究的主要发现。
一项基于人群的前瞻性队列研究；以及助听器处方和非线性频率压缩的随机对照试验。
新南威尔士州、维多利亚州和昆士兰南部的451名儿童。
3岁时语言结局的显著预测因素包括听力损失的严重程度、性别、是否存在其他残疾、母亲的教育程度以及接受人工耳蜗植入的年龄。虽然处方对结局没有显著影响，但其对响度和助听器安全性的影响对管理具有启示意义。在控制了一系列预测变量后，非线性频率压缩对结局没有显著影响。对于相同的听力敏感度，听觉神经病的存在对结局没有显著影响。
这些发现构成了听力损失儿童管理循证指南的基础。
