The health impact of a hearing disability on older people in Australia.

ABSTRACT

OBJECTIVES: A series of studies has proposed that hearing loss has adverse effects for other aspects of health. This article examines the health effects associated with self-reported hearing disability on older people. METHODS: The study utilized the 2003 Australian Survey of Disability, Ageing, and Carers (n = 43,233), a weighted population-based survey providing data on self-reported disability and quality of life, to examine hearing disability among older Australians (55 years plus). RESULTS: Of the estimated 654,113 people reporting hearing disability, 71% experienced limited communication and 60% used hearing aids. Compared with population norms, hearing disability at all levels was associated with poorer physical and mental health scores on the SF-12 measure, especially for people with severe or profound hearing loss, thus suggesting a threshold effect at advanced levels of disability. DISCUSSION: Data support emerging literature suggesting a causal relationship between hearing disability and quality of life. Prospective studies to further examine this relationship are indicated.
