In this study we aimed to evaluate the frequency of cerumen impaction in Japanese elderly and clarify the associations between cerumen, cognitive function, and hearing impairment.
The subjects enrolleded in this study were participants in the National Institute for Longevity Sciences, Longitudinal Study of Aging (NILS-LSA). The data of 792 community-dwelling participants aged 60 to 88 years old were collected. All had taken the Mini-Mental State Examination (MMSE) and had undergone pure tone audiometry (PTA) assessment and video recording of an otoscopic examination. We then analyzed associations between the incidence of the cerumen impaction of better-hearing ear, hearing level and MMSE scores using a general linear model.
Cerumen impaction of the better-hearing ear was observed in 10.7% of all participants. In participants with an MMSE score of less than 24, the frequency of cerumen impaction was 23.3%. Cerumen was significant associated with poorer hearing after adjustment for sex and age (p=0.0001). Cerumen impaction also showed a significant association with a low MMSE score after adjustment for sex, age, hearing level and education (p=0.02).
The frequency of cerumen impaction in Japanese elderly was estimated to be approximately 10%. The existence of cerumen impaction was associated with poorer hearing level and lower MMSE score.
在本研究中，我们旨在评估日本老年人耵聍栓塞的发生率，并阐明耵聍、认知功能和听力障碍之间的关联。
本研究纳入的受试者为国立长寿科学研究所衰老纵向研究（NILS-LSA）的参与者。收集了792名年龄在60至88岁的社区居住参与者的数据。所有参与者均接受了简易精神状态检查表（MMSE）检查、纯音听力测定（PTA）评估以及耳镜检查的视频记录。然后，我们使用一般线性模型分析了听力较好耳朵的耵聍栓塞发生率、听力水平与MMSE评分之间的关联。
在所有参与者中，10.7%的人存在听力较好耳朵的耵聍栓塞。在MMSE评分低于24分的参与者中，耵聍栓塞的发生率为23.3%。在对性别和年龄进行调整后，耵聍与听力较差显著相关（p=0.0001）。在对性别、年龄、听力水平和教育程度进行调整后，耵聍栓塞与低MMSE评分也显著相关（p=0.02）。
据估计，日本老年人耵聍栓塞的发生率约为10%。耵聍栓塞的存在与听力水平较差和MMSE评分较低相关。
