The impact of sensory impairment on cognitive performance, quality of life, depression, and loneliness in older adults

Objectives The objective of this study was to evaluate the relationship between sensory impairment (hearing loss only, vision loss only, and dual sensory impairment [DSI]) and depression, loneliness, quality of life, and cognitive performance in older adults. Methods A total of 229 community‐dwelling older adults aged 60 years or older participated in this study. Variables were measured using the Geriatric Depression Scale (GDS‐15), Revised University of California at Los Angeles Loneliness Scale (R‐UCLA), Satisfaction with Life Scale (SWLS), and Mini‐Mental State Examination (MMSE). Results There was an independent association between DSI and quality of life ( P < .05) and between DSI and hearing loss alone and cognitive function ( P < .05) in older adults. In addition, higher education was associated with better quality of life and cognitive function. Conclusions DSI is a significant factor affecting the quality of life and cognitive function in older adults. Sociodemographic factors such as education play an important role in improving quality of life and cognitive function. Thus, increasing the awareness of this disability is important to ensure that older adults receive the necessary support services and rehabilitation to improve their level of independence.
