The aim of this study was to evaluate health-related quality of life (HRQoL) in adults with hearing impairment in Finland before and after hearing rehabilitation.
The study was prospective with hearing-aid rehabilitation as the intervention. The data was collected, using the 15D instrument, before and six months after hearing-aid rehabilitation. The data was analysed using t-tests and multiple linear regression methods.
The study sample included 949 adults with hearing impairment, and the control group included a sample of age- and gender-standardized general population.
The study population had significantly poorer HRQoL on most dimensions of the 15D when compared to the control group both before and after hearing-aid rehabilitation. Hearing-aid rehabilitation resulted in improved mean scores on the dimensions of hearing and in the overall 15D score that were statistically significant, although the mean improvement in the overall score was marginal. Self-reported hearing ability can better predict the change in HRQoL, as a result of a hearing aid, when compared with measured hearing sensitivity.
The study supports the hypothesis that on average, use of a unilateral hearing aid results in improved subjective hearing and marginal improvement in HRQoL in adults with hearing impairment.
本研究旨在评估芬兰听力受损成年人在听力康复前后的健康相关生活质量（HRQoL）。
本研究为前瞻性研究，以助听器康复作为干预措施。在助听器康复前及康复后六个月，使用15D工具收集数据。采用t检验和多元线性回归方法分析数据。
研究样本包括949名听力受损成年人，对照组包括年龄和性别标准化的普通人群样本。
与对照组相比，研究人群在助听器康复前后的15D大多数维度上的HRQoL均显著较差。助听器康复使听力维度及总体15D评分的平均得分有所提高，具有统计学意义，尽管总体评分的平均改善幅度较小。与测量的听力敏感度相比，自我报告的听力能力能更好地预测助听器使用导致的HRQoL变化。
该研究支持以下假设：平均而言，单侧使用助听器可改善听力受损成年人的主观听力，并使HRQoL略有改善。
