Recent studies indicate that the utilization of hearing aids could potentially extend lifespan, with findings demonstrating a noteworthy reduction in the risk of mortality by nearly 25%. Despite the prevalence of hearing loss affecting millions globally, a mere fraction of those in need of hearing aids actually utilize them, with statistics indicating that only one in 10 individuals do so.
This revelation underscores the critical importance of addressing hearing loss through the adoption of appropriate interventions. Researchers at the University of Southern California, in their study published in The Lancet journal Healthy Longevity, highlight the significance of heeding medical advice regarding the use of hearing aids. For those who have been hesitant or resistant, considering a New Year’s resolution to embrace hearing aid usage may not only enhance their quality of life but also potentially contribute to their longevity.
“We found that adults with hearing loss who regularly used hearing aids had a 24 percent lower risk of mortality than those who never wore them,” said Dr. Janet Choi, the lead researcher.
“These results are exciting because they suggest that hearing aids may play a protective role in people’s health and prevent early death.”
Previous studies have highlighted the detrimental effects of untreated hearing loss, including a shorter lifespan and increased risk of depression and dementia. However, little research has explored whether using hearing aids could mitigate these risks.
Dr. Choi, an otolaryngologist at USC’s Keck Medicine, led a groundbreaking study delving into the relationship between hearing aid usage and mortality rates. This research represents the most thorough investigation to date on this topic.
Choi and her team analyzed data from a national survey conducted in 2012, focusing on nearly 10,000 adults aged 20 and above who had undergone audiometry evaluations and provided information about their hearing aid usage. Over a 10-year follow-up period, the researchers tracked the mortality status of these individuals.
Among the participants, 1,863 had hearing loss, with 237 being regular hearing aid users, defined as those who wore their aids at least once a week for a minimum of five hours or half the time. The remaining 1,483 individuals were classified as ‘never-users’ of hearing aids. Those who used the devices less than once a month were categorized as ‘non-regular’ users.
The study revealed a significant 25% lower mortality risk among regular hearing aid users compared to never-users, irrespective of factors like the severity of hearing loss, age, ethnicity, income, education, medical history, and other demographics. Conversely, there was no discernible difference in mortality risk between non-regular users and never-users, suggesting that sporadic use of hearing aids may not confer the same life-extending benefits.
Though the study didn’t delve into the mechanisms behind the observed effects, Dr. Choi highlighted previous research associating hearing aid use with reduced rates of depression and dementia. She hypothesizes that the cognitive and mental health improvements resulting from improved hearing could contribute to overall better health outcomes.
Dr. Choi’s personal experience with hearing loss, having only started using a hearing device in her 30s despite being born with hearing loss in one ear, underscores her commitment to advancing understanding and accessibility of hearing aids. She hopes that this research will inspire individuals to overcome barriers such as stigma and cost associated with acquiring hearing devices.
In addition to her research, Choi is spearheading the development of an AI-driven database aimed at categorizing hearing aid options and customizing them to suit individual patient needs, further enhancing accessibility and efficacy in hearing healthcare.
