Addressing hearing loss may reduce isolation among the elderly

(Press-News.org) Providing hearing aids and advice on their use may preserve social connections that often wane as we age, a new study shows. Its authors say that this approach could help ease the loneliness epidemic that older Americans face.

According to the U.S. Centers for Disease Control and Prevention, more than a quarter of seniors say they have little or no contact with others, and a third report feeling lonely. Experts have linked such isolation in part to hearing loss, which can interfere with communication and relationship building. The 2023 U.S. Surgeon General’s Advisory named improving social connection as great a priority as targeting tobacco use, obesity, and addiction.

Led by researchers at NYU Langone Health as part of the ACHIEVE clinical trial, the study revealed that those treated for hearing loss retained one additional social connection on average over a three-year period when compared with those who received no hearing therapies and were instead educated about healthy aging.

Publishing online May 12 in the journal JAMA Internal Medicine, the work further showed that those given hearing aids had more diverse relationships, with networks that had many different types of connections (e.g., family members, friends, and acquaintances). They also maintained deeper, higher quality bonds than those who were not treated for hearing loss.

“Our findings add to evidence that helping aging patients hear better can also enrich their social lives and boost their mental and physical well-being,” said study lead author Nicholas Reed, AuD, PhD, a member of the NYU Grossman School of Medicine’s Optimal Aging Institute.

Experts have linked both loneliness and hearing loss to depression, heart disease, and early death, among other concerns, adds Reed, also a faculty member in the Departments of Otolaryngology-Head and Neck Surgery and Population Health at NYU Grossman School of Medicine. A 2023 report on the ACHIEVE trial showed that hearing interventions may slow cognitive decline among those at highest risk for dementia.

“These results support efforts to incorporate hearing aid coverage into Medicare as a means of addressing the nation’s social isolation epidemic, which is especially risky for the elderly,” said ACHIEVE trial co-principal investigator Josef Coresh, MD, PhD. “Making sure Americans can continue engaging with their family and friends as they age is a critical part of maintaining their quality of life,” added Coresh, also the Terry and Mel Karmazin Professor in the Department of Population Health.

For the study, the research team collected data about older adults with untreated hearing loss across four sites in Maryland, North Carolina, Minnesota, and Mississippi. The study is among the largest to date to explore if hearing care can help prevent weakening of social networks, having included nearly 1,000 men and women ages 70 through 84.

Half of the participants received hearing aids, counseling sessions and personalized instruction with an audiologist, and when needed, tools such as adaptors that connect hearing aids to televisions. The other half of the participants were given instruction about exercise, strategies for communicating with healthcare providers, and further resources for healthy aging.  

To measure social isolation, the researchers assessed how regularly participants spent time with others, the size and variety of their social networks and the roles they played in them, and the depth of their connections. Loneliness was calculated using a 20-question scoring system that evaluates how often a person feels disconnected from others. After the initial data was collected, the team followed up at six months and then every year for three years.

Among the other findings, the study revealed that before treatment, participants in both groups reported feeling equally lonely. Three years after the intervention took place, loneliness scores slightly improved among those who had received hearing care, while scores slightly worsened among those who did not.

Hearing aids and their related audiology appointments cost an average of $4,700, which is usually paid out of pocket, notes Coresh, who is the founding director of the Optimal Aging Institute.  

Also a professor in the Department of Medicine, Coresh says the authors plan to continue following the participants for another three years and to repeat the study with a more diverse group of people—the patients were mostly White. He cautions that the participants received concierge-level hearing care that provided more resources and time with audiologists than is typically offered to the public. Damaged hearing aids, for example, were replaced within days instead of weeks.  

Funding for the study was provided by National Institutes of Health grants R01AG055426, R01AG060502, U01HL096812, U01HL096814, U01HL096899, U01HL096902, and U01HL096917.

In addition to Reed and Coresh, NYU Langone researcher James Pike, MBA, was involved in the study.
