A Study of Hearing Measurement and Cognitive Function of the Elderly at a Private Residential Home

By 川上 紀子 and 福田 章一郎


 高齢者への聴力検査の正確かつ効率的な方法を検討すると同時に難聴者の聴力の程度,難聴の質,補聴状況および認知機能との関係について有料老人ホームを利用している高齢者35例を対象に調査,検討を行った.その結果,対象の91.1%に片側あるいは両側に難聴が認められ,このうち39.7%が中等度難聴であった.認知面においては62.9%に認知機能の低下が認められた.しかしながら,認知機能と聴力検査にかかる時間には相関は認められなかった.選別聴力検査結果と精密検査である標準純音聴力検査結果の間には高い相関関係が認められた.聴力検査の所要時間と認知機能の間には関係が認められなかった.難聴を自覚していたのは難聴者の60.0%であった.難聴の自覚困難は補聴器装用の遅れの原因となりかねない.高齢者に対して負担の少ない選別聴力検査結果の補聴器フィッティングへの有用性が示唆された.また,難聴の発見及び啓発の機会を提供し,補聴器によるQOL の向上に結び付けるシステム作りが必要であると考えられた. In this study, intended for 35 cases of the elderly, accurate and efficient hearing test methods of for the elderly were studied. In addition, we researched and also considered the relationship between the cognitive function and degree of hearing, and the hearing aid situation. As a result, the hearing loss was observed in one or both sides in 91.1% of the objects, and among those 39.7% had moderate hearing loss. Cognitive impairment was observed in 62.9%. However, no correlation was observed cognitive function and the time it takes for both screening audiometry or standard pure-tone audiometry. High correlation was observed between results of the standard pure-tone audiometry and results of screening audiometry. It was suggested that results of screening audiometry which is less burdensome than the standard pure-tone audiometry are useful for the fitting of the hearing aid for the elderly. Also, the necessity of making a system, linked to the improvement of QOL by the use of hearing aids, which would provide opportunities for the awareness and discovery of hearing loss in the elderly was considered
