Study Links Hearing Aid Use to Lower Frailty Risk

A new study published in the July 9 edition of the Journal of the American Geriatrics Society suggests that older adults with poorer hearing are more likely to show signs of frailty—but that relationship appears to be weaker among people who use hearing aids.

The study, “Hearing Aid Use Attenuates the Association Between Hearing Loss and Frailty,” analyzed data from 2,644 adults aged 65 and older who participated in the National Health and Nutrition Examination Survey (NHANES) from 2003 to 2018. Unlike many earlier studies that relied on self-reports of hearing difficulty, this analysis used pure-tone audiometry, the standard hearing test in clinical practice. Hearing ability was based on the better-ear pure-tone average at 500, 1000, 2000, and 4000 Hz—frequencies important for speech understanding.

The researchers also used a broad definition of frailty. Rather than focusing only on physical signs such as weakness, exhaustion, or slow walking, they used a 52-item “frailty index” based on the accumulation of health deficits. These deficits included cognitive, physical, functional, medical, and laboratory measures. Participants were classified as robust, pre-frail, or frail based on their frailty index scores.

Overall, 22.5% of older adults in the study were classified as frail, and 39.7% were classified as pre-frail. After adjusting for age, race and ethnicity, education, sex, and occupational noise exposure, each 10 dB increase in hearing threshold (poorer hearing) was associated with 24% higher odds of frailty compared with being robust. When frailty was analyzed as a continuous score, each 10 dB worsening in hearing was associated with a 6.9% higher frailty index score.

Hearing Aid Use Improves Risk Against Frailty

The most notable finding involved hearing aid use. Among participants with at least mild hearing loss, poorer hearing was linked to higher frailty scores in people who did not use hearing aids. For non-users, each 10 dB worsening in hearing was associated with a 17.9% higher frailty index score. Among hearing aid users, however, that association was essentially absent: the corresponding estimate was -4.2%, with a confidence interval crossing zero. In other words, worsening hearing was associated with greater frailty among non-users, but not among hearing aid users.

The authors also examined whether the hearing-frailty relationship differed by sex. It did not. Although hearing loss and frailty can affect men and women differently, the study found no evidence that gender altered the association between poorer hearing and frailty.

For consumers, the key message is not that hearing aids have been proven to prevent frailty. This was a cross-sectional study, meaning hearing, hearing aid use, and frailty were measured at the same general point in time. Because of that, the study cannot prove whether hearing loss contributes to frailty, whether frailty affects a person’s likelihood of using hearing aids, or whether other factors influence both. The authors also noted that hearing aid use was not measured consistently across all survey years; in most cycles, NHANES asked whether participants had ever used hearing aids, not whether they were current or consistent users.

Despite those limitations, the findings contribute to a growing body of research linking hearing health to broader aspects of healthy aging. Frailty isn’t all about aging; it reflects a person’s reduced reserve and increased vulnerability to stressors such as illness, falls, hospitalization, cognitive decline, or functional loss. It’s possible that hearing loss contributes to this vulnerability through several pathways, including social isolation, cognitive load, reduced situational awareness, depression, falls, and reduced activity. The authors argue that improved access to hearing aids could help reduce downstream effects of hearing loss and frailty, both of which contribute to the burden of age-related disability.

For audiologists and hearing care professionals, the study reinforces the importance of treating hearing loss as more than an isolated sensory issue. A hearing evaluation may provide useful information not only about communication needs but also about an older adult’s overall functional health. The paper also highlights the potential value of integrating hearing data into electronic health records and frailty screening tools—particularly as hospitals respond to age-friendly care requirements.

Although the study does not prove that hearing aids prevent frailty, it strengthens the case that hearing loss is a potentially modifiable risk factor for healthy aging—and that improved access to hearing care may yield benefits beyond improved hearing alone.
