研究老年听障患者的认知功能、年龄和听力损失与临床评估的助听器益处的关系。通过在安静和嘈杂环境中进行语音识别的客观测量以及使用标准化问卷反映日常情况的主观测量来评估助听器的益处。广泛的一般认知功能，如注意力，记忆力和智力是通过不同的神经心理学测试来确定的。以神经心理测试结果、年龄和听力损失为自变量，以获益措施为因变量，进行线性回归分析。30名经验丰富的老年助听器使用者参与了研究。大多数益处测量显示，佩戴助听器的参与者获得了显著的改善。回归模型显示，流体智力测量与助听器的客观效益之间存在显著关系。当个体听力阈值被视为一个额外的自变量时，听力损失是效益模型中唯一重要的贡献者。较低的认知能力——由液态智力测试确定——与更严重的听力损失显著相关。主观效益不能通过考虑的任何变量来预测。目前的研究并没有提供证据表明助听器的益处与经验丰富的助听器使用者的认知功能密切相关。然而，研究发现，较低的流体智力得分与较高的听力阈值有关。由于更大的听力损失与更大的客观利益相关，这些结果强烈支持使用助听器的建议，无论年龄和认知功能如何，以对抗听力损失和与年龄相关的听力障碍的不利影响。尽管如此，如果尚未发生适应，在助听器提供的初始阶段，个人认知能力可能与助听器的益处有关。
To examine the association of cognitive function, age, and hearing loss with clinically assessed hearing aid benefit in older hearing-impaired persons. Hearing aid benefit was assessed using objective measures regarding speech recognition in quiet and noisy environments as well as a subjective measure reflecting everyday situations captured using a standardized questionnaire. A broad range of general cognitive functions such as attention, memory, and intelligence were determined using different neuropsychological tests. Linear regression analyses were conducted with the outcome of the neuropsychological tests as well as age and hearing loss as independent variables and the benefit measures as dependent variables. Thirty experienced older hearing aid users with typical age-related hearing impairment participated. Most of the benefit measures revealed that the participants obtained significant improvement with their hearing aids. Regression models showed a significant relationship between a fluid intelligence measure and objective hearing aid benefit. When individual hearing thresholds were considered as an additional independent variable, hearing loss was the only significant contributor to the benefit models. Lower cognitive capacity – as determined by the fluid intelligence measure – was significantly associated with greater hearing loss. Subjective benefit could not be predicted by any of the variables considered. The present study does not give evidence that hearing aid benefit is critically associated with cognitive function in experienced hearing aid users. However, it was found that lower fluid intelligence scores were related to higher hearing thresholds. Since greater hearing loss was associated with a greater objective benefit, these results strongly support the advice of using hearing aids regardless of age and cognitive function to counter hearing loss and the adverse effects of age-related hearing impairment. Still, individual cognitive capacity might be relevant for hearing aid benefit during an initial phase of hearing aid provision if acclimatization has not yet taken place.
