Hearing Loss and Falls Among Older Adults in the United States

To the Editor

Identifying modifiable risk factors for falls in older adults is of significant public health importance. While hearing is not typically considered a risk factor for falls, a recent report in a cohort of older Finnish female twins has demonstrated a strong association between audiometric hearing loss and incident falls 1. Possible pathways that could explain this observed association include shared cochlear and vestibular pathology, poor awareness of the auditory and spatial environment, or mediation through the effects of hearing loss on cognitive load and shared attention. These latter two pathways that suggest a possible causal pathway between hearing loss and falling are intriguing because hearing loss is highly prevalent but remains vastly undertreated in older adults 2, 3. The objective of this current study was to investigate the cross-sectional association of audiometric hearing loss with self-reported falls in a representative sample of the United States population ages 40–69 years participating in the National Health and Nutritional Examination Survey (NHANES).


Study subjects

Subjects were participants (age 40–69 years) in the 2001–2004 cycles of NHANES who had assessment of audiometric hearing loss and fall history. During this period, audiometry was administered to a half sample of all adults 20–69 years, and an interviewer-administered questionnaire on fall history was administered to all adults 40 years and older. The NHANES is an ongoing program of studies that assesses the health and functioning of representative cross-sectional samples of the civilian, non-institutionalized U.S. population4.

Pure tone audiometry was performed by a trained examiner according to established NHANES protocols (see eAppendix). Hearing loss was defined by a speech-frequency pure tone average (PTA) of thresholds at 0.5, 1, 2, and 4 kHz in the better hearing ear per the definition of hearing loss adjudicated by the World Health Organization 5. Fall history was ascertained in an interviewer-administered questionnaire (“Have you had difficulty with falling during the past 12 months”). Data on demographic variables and medical history were obtained from interviews. Objective vestibular balance testing consisted of test condition 4 of the Modified Romberg Test of Standing Balance on Firm and Compliant Support Surfaces (eAppendix).

Logistic regression was used to analyze the association between hearing loss and self-reported falling while adjusting for age and other covariates. We accounted for the complex sampling design in all analyses by using sample weights according to National Center for Health Statistics (NCHS) guidelines. All analyses were conducted using STATA 11.1 (StataCorp, College Station, TX), and 2-sided p-values <.05 were considered statistically significant.


From 2001–2004, 2017 participants age 40–69 years had concurrent assessment of hearing loss and fall history in NHANES (eTable). Hearing loss >25dB was prevalent in 14.3% of these participants, and 4.9% of the participants reported falling over the preceding 12 months. We examined the association of hearing loss with having self-reported falls in stepwise logistic regression models. In an unadjusted model, hearing loss was significantly associated with the odds of reported falls. For every 10 dB increase in hearing loss, there was a 1.4 fold (95% CI: 1.3–1.5) increased odds of an individual reporting falling over the preceding 12 months. Adjustment for demographic factors (age, sex, race, education), cardiovascular factors (smoking, diabetes, hypertension, stroke), and vestibular balance function did not substantially change the magnitude or significance of this association (Table). Restricting the analytical cohort to only those participants with hearing loss ≤ 40 dB (thereby excluding those with a moderate or severe hearing loss) did not affect the magnitude of our results (c.f. Table).

In this nationally-representative study of 40–69 year-old adults, greater hearing loss was independently associated with self-reported falls over the preceding 12 months. These results were robust to analyses accounting for multiple confounders, excluding participants with moderate or severe hearing loss, and after adjustment for vestibular balance function. The magnitude of the association of hearing loss with falls is clinically-significant with a 25 dB hearing loss (equivalent from going from normal to mild hearing loss) being associated with a nearly three-fold increased odds of reporting falling over the preceding year.

Our results contribute to the literature examining the association between hearing loss and falls. Our findings are consistent with prior research studies that have utilized both self-reported6 and audiometric 1, 7 measures of hearing and have demonstrated associations between hearing loss with balance function 7 and incident falls 1. In contrast, another longitudinal study has not found similar associations 8. Potential factors that may limit the consistency of reported results across studies are variability in how hearing loss was measured, variability in cohort characteristics, and how balance and falls were assessed. For example, in studies using a hearing screening instrument rather than pure tone audiometry 8, any misclassification of hearing loss status by the screening device may bias any observed results toward the null hypothesis

A number of mechanisms could explain the observed association between hearing loss and falls. There may be concomitant dysfunction of both the cochlear and vestibular sense organs given their shared location within the bony labyrinth of the inner ear. Decreased hearing sensitivity may also directly limit access to auditory cues that are needed for environmental awareness. Finally, the association of hearing loss with falls may be mediated through cognitive load and reduced attentional resources. Attentional resources are critical for maintaining postural control 9, and decrements in attentional and cognitive resources imposed by hearing loss 10 may impair the maintenance of postural balance in real-world situations and increase the risk of falling.

A key limitation of our study is that our results are based on cross-sectional data rather than on longitudinal trajectories of hearing loss and fall history over time. Our measure of fall history was also dependent on retrospective self-report. However, our results were generally consistent with other studies 1, 6, 7, and our results demonstrated a robust association between hearing loss and falls after adjustment for multiple confounders.

Further prospective research is needed to determine whether hearing loss is a modifiable risk factor for falls that may be amenable to hearing rehabilitative strategies that remain underutilized.
