NEW YORK, Jan 4: A new study published in The Lancet Healthy Longevity by researchers at Keck Medicine of USC suggests that incorporating hearing aid use into one's lifestyle could be a crucial New Year's resolution for those experiencing hearing loss. Despite an estimated 40 million American adults grappling with hearing impairment, only one in 10 individuals who require hearing aids use them, according to the research.

The study, led by Dr. Janet Choi, an otolaryngologist with Keck Medicine, revealed compelling findings regarding the potential impact of hearing aid usage on mortality risk. Dr. Choi stated, "We found that adults with hearing loss who regularly used hearing aids had a 24% lower risk of mortality than those who never wore them. These results are exciting because they suggest that hearing aids may play a protective role in people's health and prevent early death."

Previous research has demonstrated the adverse effects of untreated hearing loss, including a reduced lifespan, social isolation, depression, and dementia. However, this study is the most comprehensive analysis to date on the relationship between hearing loss, hearing aid use, and mortality in the United States.

The researchers utilized data from the National Health and Nutrition Examination Survey (1999-2012) to identify nearly 10,000 adults aged 20 and older who underwent audiometry evaluations and provided information about their hearing aid use. Over a 10-year average follow-up period, the study found a consistent 25% difference in mortality risk between regular hearing aid users and never-users, irrespective of variables such as the severity of hearing loss, age, ethnicity, income, education, and medical history.

While the study did not delve into the specific mechanisms behind the life-extending benefits of hearing aid use, Dr. Choi pointed to recent research associating it with reduced levels of depression and dementia. Improved mental health and cognition resulting from enhanced hearing may contribute to overall better health, potentially extending life span.

Despite acknowledging barriers such as cost, stigma, and difficulties finding suitable devices, Dr. Choi, who personally understands these challenges, hopes the study will encourage more people to adopt hearing aids. She is currently working on an AI-driven database to tailor hearing aid choices to individual needs and advocates for larger studies to deepen the understanding of the link between regular hearing aid use and lower mortality risk, ultimately promoting hearing care.
