Instructions for Using the Adult Hearing Website

For Primary Care Physicians & Hearing Health Professionals

The Adult Hearing website is designed as a trusted, evidence-based, unbranded resource to support referring providers, guide clinical decision-making, enhance patient education, and promote timely referral to appropriate hearing care. Below are clear steps on how to navigate, use, and integrate the website effectively in clinical practice.

1. Start at the Homepage to Understand the Foundations

The homepage provides a concise overview of:

  • The impact of hearing on overall health, including connections with cognitive health, mental health, chronic diseases, and quality of life.
  • Why early identification and management of hearing loss is essential.

Methodology

Observational population study on 52,219 South Korean adults with severe hearing loss and 1,280,788 individuals with normal hearing to investigate whether auditory rehabilitation—specifically cochlear implants (CI) and hearing aids (HA)—reduces the long-term risk of dementia

Health and Retirement Study (HRS) of 5,270 US community-dwelling adults aged 65+ to investigate whether social isolation among older adults is associated with increased Medicare spending.

Findings and recommendations

  • Social isolation is a significant social determinant of health contributing to higher health care costs and poorer health outcomes.
  • Screening: Develop tools to identify socially isolated Medicare beneficiaries.
  • Interventions: Fund culturally competent programs to reduce isolation
  • Integration: Include social isolation in public health frameworks and Medicare wellness visits.
  • Awareness: Elevate social isolation as a public health priority.

Methodology
Systematic literature review and meta-analysis to evaluate the impact of hearing rehabilitation devices

Findings and recommendations

  • Hearing aids and cochlear implants improve social engagement and reduce feelings of social handicap.
  • Cochlear implants showed greater benefits, possibly due to more severe baseline hearing loss and structured rehabilitation.
  • Longer duration of device use was linked to greater improvements in social outcomes.
  • Hearing rehabilitation should be encouraged to reduce social withdrawal and its downstream effects (e.g., social isolation, cognitive decline).
  • Improved social outcomes may contribute to better overall well-being and mental health.

Methodology
Cross-sectional analysis of 3,384 adults with diabetes

Findings and recommendations

  • 59.3% had high-frequency hearing impairment.
  • 21.6% had combined high + low/mid-frequency hearing impairment

Caballero-Borrego M, Andujar-Lara I. Type 2 diabetes mellitus and hearing loss: A PRISMA systematic review and meta-analysis. Otolaryngol Head Neck Surg. 2025;173(5):1041–1053

Methodology
Systematic review and meta-analysis of 17 papers

Findings and recommendations

  • Diabetic patients had a 4.19 times higher risk of HL compared to controls
  • HL in T2DM may be linked to microvascular complications (e.g., cochlear microangiopathy).
  • HL often begins at high frequencies and may be detected early with high-frequency audiometry

Deng Y, Chen S, Hu J. Diabetes mellitus and hearing loss. Mol Med. 2023;29(1):141.

Methodology
Narrative review

Findings and recommendations

  • DM increases both the prevalence and severity of sensorineural hearing loss (SNHL).
  • Hearing loss in DM patients tends to start at high frequencies and progresses to lower frequencies with age
  • DM causes damage to cochlear vasculature, Organ of Corti & Spiral ganglion neurons and afferent nerve fibers

Health statistics from US

Findings and Recommendations

  • In people from 18-44 6,1% had hearing trouble, 45-64 17.8%, 65-74 31.6% and 75+ 47.2%

Objective:

Assess time from hearing aid candidacy to adoption

Methodology:

Longitudinal study of 1.530 adults in US

Findings and Recommendations

  • Average delay from candidacy to adoption: 8.9 years
  • Predictors of faster adoption: Greater high-frequency hearing loss, Higher self-reported hearing handicap, Poorer speech recognition in noise (
  • Predictors of slower adoption: Non-white race,Better speech recognition in difficult tasks
  • Recommendation to promote early identification and treatment to improve communication and reduce negative health impacts.

Objective:

Summarise risk factors and health impact from hearing loss

Methodology:

Informational review

Findings and Recommendations

  • Hearing loss prevalence increases with age and is the third most common chronic condition in US
  • Risk factors include: Sleep apnea, diabetes, high blood pressure, high cholesterol, cardiovascular disease
  • Health impact from hearing loss include: Social isolation, depression, anxiety, falls and injuries, cognitive decline
  • Recommendation to get an annual health checkup and schedule appointment with audiologist if you suspect hearing loss

Objective:

Evaluate if untreated hearing loss associated with higher health care costs and utilization

Methodology:

Retrospective study of insurance database of 154.414 subjects

Findings and Recommendations

  • Untreated hearing loss was associated with 46% higher hearth care costs over a 10-year period
  • Patients with hearing loss experienced more in-patient stays and were at greater risk for 30-day readmission
  • Longer length of hospital stays at 2, 5, and 10 years following initial hearing loss diagnosis

Objective:

Re-estimate rates of bilateral hearing loss Nationally, and create new estimates of hearing loss prevalence at the U.S. State and County levels

Methodology:

Small Area Estimation Modelling

Findings and Recommendations

  • Hearing loss affects 37,9 million in US with 24,9 million having mild loss and 13 million having a moderate or worse HL
  • Rates of hearing loss increase sharply with age with 72,7% aged 75+ having hearing loss
  • Rural communities have higher prevalence than urban areas
  • Recommending to target public hearth interventions for identification, prevention and treatment
  • Allocate resources to rural and high prevalence areas
