Association Between Hearing Level and Mental Health and Quality of Life in Adults Aged >40 Years

Abstract

Background and Objectives: In this study, we investigated the effects of hearing loss on mental health and quality of life (QoL) using survey data in adults aged >40 years.Subjects and Methods: We obtained data from 10,921 individuals who responded to the fifth Korean National Health and Nutrition Examination Survey. Primary outcomes were measured using questionnaires that recorded stress perception, depressive mood, and suicidal ideation to evaluate mental health and motor ability, self-management, activities of daily living, pain or discomfort, and anxiety or depression to evaluate QoL.Results: On multivariate analysis, suicidal ideation was more prevalent among older adults with hearing loss than in older adults without hearing loss. Motor ability was lower in individuals with hearing loss of >20 dB than in older adults with normal hearing. Categorization of the EuroQol-5 Dimension (EQ-5D) health state into upper and lower groups showed that the EQ-5D values were lower in the moderate-tosevere hearing loss group than in the mild hearing loss group.Conclusions: Among adults aged >40 years, those with hearing loss experienced more suicidal ideation, had lower motor ability, and lower overall QoL compared with these variables in older adults with normal hearing. Additionally, QoL scores were low in individuals with poor hearing.
