Unmet hearing health care needs: the Beaver Dam offspring study

Demographic Disparities in Drive Times to the Nearest Audiologist in the United States

PURPOSE

Audiological services are underused, possibly because patients need to drive long distances to see a provider. In this study, we measured the association of drive times to the nearest audiologist with population density, income, ethnicity, race, and distance to the nearest audiology graduate program.

METHOD

Drive times for each census block group to the nearest audiologist were measured using census data, the National Provider Identifier Registry, and a geographic analyzing tool called ArcGIS for all block groups within the United States. The association between drive times and population density, income, ethnicity, race, and audiology program distance was evaluated with a population density-matched case-control study and multiple linear regression analyses.

RESULTS

Approximately 5.29 million Americans need to drive at least 1 hr to visit their closest audiologist. The 10% most rural-dwelling Americans drive an average of 33.8 min. The population density-matched case-control study demonstrated that percent below poverty, percent identifying as Hispanic, and travel times to the nearest audiology program were all significantly higher in census block groups with high drive times to the nearest audiologist. An average of 7.96% of individuals in census block groups with low drive times identified as Hispanic, but 18.8% identified as Hispanic in high drive time groups. The multiple linear regression showed that the effect of demographics and distance to the nearest audiology program was highest in rural areas. In both analyses, adjusting for poverty did not drastically change the effect of percent identifying as Hispanic on drive times.

CONCLUSIONS

Long drive times restrict access to audiological care for those who live in rural areas. This restriction disproportionately affects those in rural areas who identify as Hispanic or have low income.

Demographic and Audiological Characteristics of Candidates for Over-the-Counter Hearing Aids in the United States

OBJECTIVES

This report presents descriptive data on the demographic and audiological characteristics of US adults with perceived mild-to-moderate hearing loss, the primary candidates for over-the-counter (OTC) hearing aids.

DESIGN

The analyses are descriptive and present population-weighted responses for various self-reported demographic and audiological variables for adults with mild or moderate perceived hearing trouble. Results of pure-tone audiometry and immittance measures are also presented. Nationally representative datasets from the National Health and Nutrition Examination Surveys (NHANES) for 2011 to 2012, 2015 to 2016, and 2017 to 2020, the three most recent NHANES datasets with audiological information, were used.

RESULTS

The NHANES datasets indicated that there are 49.5 million adults in the United States with perceived mild-to-moderate hearing trouble. Results indicated that OTC hearing-aid candidates are most frequently 50 to 69 years of age, married, and identify as non-Hispanic White race/ethnicity. Most of these individuals graduated from high school, had several risk factors for hearing loss, had not had a hearing test in the past 5 years, and had never used hearing aids or assistive listening devices previously. The typical audiometric profile was a bilaterally symmetrical sloping hearing loss with slight to mild hearing loss above 2000 Hz. Group data showed normal immittance measures and absence of otoscopic abnormalities except for the presence of excessive (not impacted) cerumen in about 13% of the OTC hearing-aid candidates.

CONCLUSIONS

Tens of millions of US adults have perceived mild-to-moderate hearing trouble but have not pursued assistance, either through obtaining a hearing test or acquiring prescription hearing aids.

Bluetooth Noise-Canceling Headphones Improve the Quality of Ophthalmic Exams in Patients With Hearing Loss: A Randomized Controlled Trial

INTRODUCTION

This study tests the utilization of Bluetooth noise-canceling headphones in improving the quality of eye exams in patients with hearing loss. This prospective study was approved on ethical standards by the University of Texas Medical Branch (UTMB) Institutional Review Board (Approval No. 22-0079) and registered with the National Institutes of Health (NCT05420038).

METHODS

UTMB patients above 55 years of age were screened for hearing loss using soundcheck audiometry. Twenty-nine subjects answered pre-recorded ophthalmic exam questions that solicited precise responses. As controls, subjects were randomly administered half of the questions via headphones and half via a smartphone at normal speech volume (60 decibels). Points were awarded for responses demonstrating comprehension, and a post-exam survey was collected.

RESULTS

Collectively, the mean score was 1.79 with headphones versus 0.96 with control on the Amsler grid segment and 1.90 with headphones versus 0.97 with control on education questions (p=0.001). Between red zone and yellow zone hearing loss patients, the more severe red zone group answered significantly better in both Amsler (1.78 versus 0.50; p=0.0003) and education questions (1.88 versus 0.44; p<0.0001) with headphones. The yellow zone group answered better with headphones overall but failed to reach significance. Post-exam survey indicated that 28 of 29 patients (97%) preferred the headphones during ophthalmic exams.

CONCLUSION

Patients with hearing loss demonstrated better comprehension with Bluetooth headphones. These low-cost devices show great promise at improving effective, compassionate communication between providers and hearing loss patients.

Hearing healthcare utilisation among older adults with self-reported hearing loss during the COVID-19 pandemic in the United States

OBJECTIVE

To ascertain the prevalence, causes, and risk factors of hearing healthcare delays in older people with self-reported hearing loss in the United States.

DESIGN

This cross-sectional study used data from the National Health and Ageing Trends Study (NHATS), a nationally representative survey of Medicare beneficiaries. A supplemental COVID-19 survey was mailed to the participants from June to October 2020.

STUDY SAMPLE

By January 2021, 3257 participants had returned completed COVID-19 questionnaires, with the majority having been self-administered between July and August 2020.

RESULTS

The participants in the study represented 32.7 million older adults in the US, with 29.1% reporting hearing loss. Among over 12.4 million older adults who put off needed or planned medical care, 19.6% of those with self-reported hearing loss and 24.5% of hearing aid or device users stated they delayed hearing appointments. Approximately 629,911 older adults with hearing devices were impacted by the COVID-19 outbreak for audiological services. The top three reasons were deciding to wait, service cancellation, and fear of going. Education and race/ethnicity were associated with delaying hearing healthcare.

CONCLUSIONS

The COVID-19 pandemic impacted hearing healthcare utilisation among older adults with self-reported hearing loss in 2020, with both patient- and provider- initiated delays.

A Perspective on Auditory Wellness: What It Is, Why It Is Important, and How It Can Be Managed

During the last decade, there has been a move towards consumer-centric hearing healthcare. This is a direct result of technological advancements (e.g., merger of consumer grade hearing aids with consumer grade earphones creating a wide range of hearing devices) as well as policy changes (e.g., the U.S. Food and Drug Administration creating a new over-the-counter [OTC] hearing aid category). In addition to various direct-to-consumer (DTC) hearing devices available on the market, there are also several validated tools for the self-assessment of auditory function and the detection of ear disease, as well as tools for education about hearing loss, hearing devices, and communication strategies. Further, all can be made easily available to a wide range of people. This perspective provides a framework and identifies tools to improve and maintain optimal auditory wellness across the adult life course. A broadly available and accessible set of tools that can be made available on a digital platform to aid adults in the assessment and as needed, the improvement, of auditory wellness is discussed.

Association between insurance status and hearing healthcare use in the United States

OBJECTIVE

Despite the high prevalence and morbidity of hearing loss, many individuals with hearing loss do not have access to hearing healthcare. This study aims to assess the relationship between insurance status and prior audiogram, and hearing aid use among subjects with hearing loss.

MATERIALS AND METHODS

This cross-sectional study of the 2009-10, 2011-12, and 2015-16 cycles of the U.S. National Health and Nutrition Examination Survey (NHANES) included 5270 adult subjects 18 years or older with subjective or audiometric hearing loss. Subjects were stratified by insurance: Medicare, Medicaid, private, uninsured, and 'other or unspecified'.

RESULTS

After adjusting for covariates, among subjects with audiometric hearing loss, prior audiogram was not associated with insurance type, including no insurance (OR 0.80, 95 % CI 0.45 to 1.42), Medicare (OR 1.34, 95 % CI 0.69 to 2.59), Medicaid (OR 1.27, 95 % CI 0.55 to 2.93), or 'other or unspecified' (OR 1.73, 95 % CI 0.67 to 4.47). Hearing aid use was not associated with insurance type, including no insurance (OR 0.20, 95 % CI 0.03 to 1.29), Medicare (OR 0.56, 95 % CI 0.27 to 1.14), Medicaid (OR 2.03, 95 % CI 0.47 to 8.71), or 'other or unspecified' (OR 1.76, 95 % CI 0.59 to 5.23).

CONCLUSIONS

Health insurance status was not associated with hearing healthcare use in our nationally-representative sample of individuals with hearing loss. Given variations in hearing coverage by Medicaid between states, future studies should compare the impact of Medicaid insurance on hearing aid use between states that cover hearing aids and those that do not.

Effect of Determinants of Health on the Hearing Care Framework: An Economic Perspective

Hearing care is expanding accessibility to consumers through new service delivery channels and methods of technology distribution (see Brice et al, this issue). This diversification has the potential to overcome longstanding consumer disparities (e.g., health, socioeconomic, psychological, environmental) in receiving care and provider constraints (e.g., accessibility, geography, direct access) to delivering care that adversely impacts quality of life (e.g., social isolation, depression, anxiety, self-esteem). In this article, the reader is provided with an overview of health outcomes factors (i.e., determinants of health)-in the context of an economic framework (i.e., supply, demand)-and their effect on consumer behavior and provider preferences toward hearing healthcare services. This overview also affords readers with strategic business insights to assess and integrate future hearing care services and technology to consumers in their local markets.

Audiology, Medicine, and Pharmacy Interprofessional Preliminary Interviews and Discussions: Improving Hearing Health Care in Rural Alabama

PURPOSE

Access and affordability of hearing health care varies depending on residency and individual financial means. Those living in rural areas have limited health care resources and experience higher levels of poverty compared to those living in urban regions. The purpose of this study was to determine the feasibility of interprofessional collaboration among physicians and audiologists and pharmacists and audiologists to improve access and affordability of hearing health care in rural communities.

METHOD

Sixteen family physicians and medicine residents and 15 community pharmacists participated in the study. Physicians and residents completed an online survey to assess education regarding hearing health care and their understanding of hearing loss intervention. They also participated in small virtual focus group discussions. Pharmacists participated in virtual discussions based on guided questions.

RESULTS

The discussions with both physicians and pharmacists highlighted the need for more education, resources, and awareness of the negative impact of hearing loss on overall quality of life. Comments from these discussions were placed within the socio-ecological model of health behavior to increase understanding of hearing health behavior.

CONCLUSIONS

Increased collaboration among medical professionals has the potential to improve access to hearing health care for those living in audiologically underserved regions of the country. Further research will identify how to increase effective and sustainable hearing health care resources in rural communities.

A pragmatic clinical trial of hearing screening in primary care clinics: cost-effectiveness of hearing screening

BACKGROUND

Hearing loss is a high prevalence condition among older adults, is associated with higher-than-average risk for poor health outcomes and quality of life, and is a public health concern to individuals, families, communities, professionals, governments, and policy makers. Although low-cost hearing screening (HS) is widely available, most older adults are not asked about hearing during health care visits. A promising approach to addressing unmet needs in hearing health care is HS in primary care (PC) clinics; most PC providers (PCPs) do not inquire about hearing loss. However, no cost assessment of HS in community PC settings has been conducted in the United States. Thus, this study conducted a cost-effectiveness analysis of HS using results from a pragmatic clinic trial that compared three HS protocols that differed in the level of support and encouragement provided by the PC office and the PCPs to older adults during their routine visits. Two protocols included HS at home (one with PCP encouragement and one without) and one protocol included HS in the PC office.

METHODS

Direct costs of the HS included costs of: (1) educational materials about hearing loss, (2) PCP educational and encouragement time, and (3) access to the HS system. Indirect costs for in-office HS included cost of space and minimal staff time. Costs were tracked and modeled for each phase of care during and following the HS, including completion of a diagnostic assessment and follow-up with the recommended treatment plan.

RESULTS

The cost-effectiveness analysis showed that the average cost per patient is highest in the patient group who completed the HS during their clinic visit, but the average cost per patient who failed the HS is by far the lowest in that group, due to the higher failure rate, that is, rate of identification of patients with suspected hearing loss. Estimated benefits of HS in terms of improvements in quality of life were also far greater when patients completed the HS during their clinic visit.

CONCLUSIONS

Providing HS to older adults during their PC visit is cost-effective and accrues greater estimated benefits in terms of improved quality of life.

Awareness, Perceptions, and Literacy Surrounding Hearing Loss and Hearing Rehabilitation Among the Adult Population in the United States

OBJECTIVE

To characterize current awareness, perceptions, and literacy surrounding hearing loss among the adult population in the United States.

STUDY DESIGN

National cross-sectional survey study.

SETTING

United States.

PATIENTS

Adults between 50 and 80 years of age in the United States.

RESULTS

Survey respondents included 1,250 adults between the ages of 50 and 80 years, including 500 who indicated at least moderate hearing loss and were using hearing aids and 750 who denied having hearing loss and were not using hearing aids.Only 9% of patients were able to correctly identify what constitutes a "normal" or "average" range for hearing. By comparison, a "normal" range of values for vision, blood pressure, and total cholesterol were identified correctly by 93%, 85%, and 52% of the 1,250 surveyed adults, respectively. When asked to rank the importance of addressing hearing loss within the context of 10 other common health conditions, hearing loss was ranked third to least important. When considering annual health maintenance, respondents indicated they were "very likely" to have an annual physical exam (72%), a cholesterol test (70%), an eye exam (66%), and bring their pet to a veterinarian (59%) over twice as frequently as having their hearing evaluated (27%).When evaluating awareness surrounding associations between hearing loss and other health and social issues, less than one-fourth indicated strong awareness about links between hearing loss and depression, employability and income, fall risk, dementia, and type 2 diabetes. While most patients acknowledge the potential impacts of hearing loss on safety, quality of life, and health, less than half believe that hearing loss is treatable and less than 20% believe that hearing loss is preventable.

CONCLUSION

Despite widespread literacy of what constitutes normal vision, blood pressure, and total cholesterol levels, respondents exhibit substantially poorer understanding of "normal" hearing levels. Most adults believe that few treatment options exist for the management of hearing loss. Underlying the uniformly limited literacy surrounding hearing loss and its treatment options is the adult population's lack of appreciation for the long-term health sequelae of untreated hearing loss.

Estimating need and coverage for five priority assistive products: a systematic review of global population-based research

INTRODUCTION

To improve access to assistive products (APs) globally, data must be available to inform evidence-based decision-making, policy development and evaluation, and market-shaping interventions.

METHODS

This systematic review was undertaken to identify studies presenting population-based estimates of need and coverage for five APs (hearing aids, limb prostheses, wheelchairs, glasses and personal digital assistants) grouped by four functional domains (hearing, mobility, vision and cognition).

RESULTS

Data including 656 AP access indicators were extracted from 207 studies, most of which (n=199, 96%) were cross-sectional, either collecting primary (n=167) or using secondary (n=32) data. There was considerable heterogeneity in assessment approaches used and how AP indicators were reported; over half (n=110) used a combination of clinical and self-reported assessment data. Of 35 studies reporting AP use out of all people with functional difficulty in the corresponding functional domains, the proportions ranged from 4.5% to 47.0% for hearing aids, from 0.9% to 17.6% for mobility devices, and from 0.1% to 86.6% for near and distance glasses. Studies reporting AP need indicators demonstrated >60% unmet need for each of the five APs in most settings.

CONCLUSION

Variation in definitions of indicators of AP access have likely led to overestimates/underestimates of need and coverage, particularly, where the relationship between functioning difficulty and the need for an AP is complex. This review demonstrates high unmet need for APs globally, due in part to disparate data across this sector, and emphasises the need to standardise AP data collection and reporting strategies to provide a comparable evidence base to improve access to APs.

Factors Affecting Hearing Aid Adoption by Adults With High-Frequency Hearing Loss: The Beaver Dam Offspring Study

PURPOSE

Hearing loss (HL) is common among middle-age and older adults, but hearing aid adoption is low. The purpose of this study was to measure the 10-year incidence of hearing aid adoption in a sample of primarily middle-age adults with high-frequency HL and identify factors associated with hearing aid adoption.

METHOD

This study included 579 adults (ages 34-80 years) with high-frequency pure-tone average > 25 dB HL (3-8 kHz) enrolled in the Beaver Dam Offspring Study. Hearing aid adoption was measured at 5- and 10-year follow-up examinations. Cox discrete-time proportional hazards models were used to evaluate factors associated with hearing aid adoption (presented as hazards ratios [HRs] and 95% confidence intervals [95% CI]).

RESULTS

The 10-year cumulative incidence of hearing aid adoption was 14 per 1,000 person years. Factors significantly associated with adoption in a multivariable model were higher education (vs. 16+ years; 0-12: HR: 0.36, 95% CI [0.19, 0.69]; 13-15: HR: 0.52, 95% CI [0.27, 0.98]), worse high-frequency pure-tone average (per +1 dB; HR: 1.04, 95% CI [1.02, 1.06]), self-reported hearing handicap (screening versions of the Hearing Handicap Inventory score > 8; HR: 1.85, 95% CI [1.02, 3.38]), answering yes to "Do friends and relatives think you have a hearing problem?" (HR: 3.18, 95% CI [1.60, 6.33]) and using closed captions (HR: 2.86, 95% CI [1.08, 7.57]). Effects of age and sex were not significant.

CONCLUSIONS

Hearing aid adoption rates were low. Hearing sensitivity, socioeconomic status, and measures of the impact of HL on daily life were associated with adoption. Provider awareness of associated factors can contribute to timely and appropriate intervention.

Perceived Hearing Loss and Availability of Audiologists in Appalachia

Introduction

There is a high demand for audiologists throughout the United States. Previous research has supported an additional demand for these providers within Appalachia.

Purpose

The purpose of the study was to determine if Appalachia has a disproportionally high demand for audiologists compared to the rest of the United States.

Methods

A cross-sectional retrospective study was performed with population data from the Appalachian Regional Commission, the American Academy of Audiology, and the United States Census Bureau. County-level population-weighted averages of individuals with perceived hearing loss and number of audiologists per capita were compared between Appalachian and non-Appalachian counties.

Results

A mean weighted 5.76 % of individuals reported hearing loss within Appalachia, which was 1.1% higher than the rest of the United States. The 1.14 audiologists per 100,000 individuals in Appalachian counties was not significantly lower than the 1.32 audiologists per 100,000 individuals found in non-Appalachian counties. Audiologists per capita decreased with increases in Beale code and percent reporting hearing loss.

Conclusion

The high number of individuals reporting hearing loss supports an increased demand for audiologists in rural Appalachia. More research is needed to determine how to meet this demand or improve the efficacy of the limited number of providers.

Factors Associated With Self-Perceived Hearing Handicap in Adults From Hispanic/Latino Background: Findings From the Hispanic Community Health Study/Study of Latinos

OBJECTIVES

We sought to determine what factors, including acculturation (language and social contact preferences), were associated with self-perceived hearing handicap among adults from Hispanic/Latino background. We utilized the Aday-Andersen behavioral model of health services utilization to frame our hypotheses that predisposing characteristics (age, sex, education, city of residence, Hispanic/Latino background, and acculturation), enabling resources (annual income and current health insurance coverage), and need (measured hearing loss and self-reported hearing loss) would be related to clinically-significant self-perceived hearing handicap as measured by the Hearing Handicap Inventory - Screening (HHI-S) version.

DESIGN

We analyzed baseline data collected from 2008 to 2011 as part of the multisite Hispanic Community Health Study/Study of Latinos. Data were from 6585 adults with hearing loss (defined by a worse-ear 500, 1000, 2000, and 4000 Hz pure-tone average [PTA] of ≥25 dB HL and/or a 4000, 6000, and 8000 Hz high-frequency PTA of ≥25 dB HL) aged 18 to 74 years from various Hispanic/Latino backgrounds. We conducted a series of multivariable logistic regression models examining the roles of independent variables of interest representing predisposing, enabling, and need indicators on the occurrence of clinically-significant self-perceived hearing handicap (e.g., HHI-S score > 8).

RESULTS

Among included participants, 953 (14.5%) had an HHI-S score >8. The final model revealed significant associations between predisposing characteristics, enabling resources, need, and HHI-S outcome. Predisposing characteristics and need factors were associated with higher odds of reporting self-perceived hearing handicap (HHI-S score >8) including acculturation as measured by the Short Acculturation Scale for Hispanics (odds ratio [OR] = 1.28, 95% confidence interval [CI]: 1.09-1.50), female sex (OR = 1.72, 95% CI: 1.27-2.33), and poorer worse ear 500, 1000, 2000, and 4000 Hz PTA (OR = 1.02, 95% CI: 1.01-1.03); suggesting that a 5-decibel increase in a person's PTA was consistent with 10% higher odds of a HHI-S score of >8. Greater enabling resources were associated with lower odds of reporting clinically-significant self-perceived hearing handicap: compared with individuals with income <$10,000/year, the multivariable-adjusted OR among individuals with income $40,000 to $7500/year was 0.55 (95% CI: 0.33-0.89) and among individuals with income >$75,000/year was 0.28 (95% CI: 0.13-0.59]; p-trend < 0.0001).

CONCLUSIONS

Our findings suggest there are associations between predisposing, enabling and need variables consistent with the Aday-Andersen model and self-perceived hearing handicap among adults from Hispanic/Latino background. The influence of language and culture on perceived hearing loss and associated handicap is complex, and deserves more attention in future studies. Our findings warrant further investigation into understanding the role of language and language access in hearing health care utilization and outcomes, as the current body of literature is small and shows mixed outcomes.

Biopsychosocial Classification of Hearing Health Seeking in Adults Aged Over 50 Years in England

Objectives:

Approximately 10 to 35% of people with a hearing impairment own a hearing aid. The present study aims to identify barriers to obtaining a hearing aid and inform future interventions by examining the biopsychosocial characteristics of adults aged 50+ according to 7 categories: (i) Did not report hearing difficulties, (ii) Reported hearing difficulties, (iii) Told a healthcare professional about experiencing hearing difficulties, (iv) Referred for a hearing assessment, (v) Offered a hearing aid, (vi) Accepted a hearing aid, and (vii) Reported using a hearing aid regularly.

Design:

The research was conducted using the English Longitudinal Study of Aging wave 7 with data obtained from 9666 adults living in England from June 2014 to May 2015. Cross-sectional data were obtained from a subset of 2845 participants aged 50 to 89 years of age with a probable hearing impairment measured by hearing screening (indicating a hearing threshold of >20 dB HL at 1 kHz or >35 dB HL at 3 kHz in the better ear). Classification according to hearing health-seeking category was via participants’ self-report. Participants in each category were compared with people in all subsequent categories to examine the associations between each category and biopsychosocial correlates (sex, age, ethnicity, educational level, wealth, audiometric hearing level, self-reported health status, cognitive performance, attitudes to aging, living alone, and engagement in social activities) using multiple logistic regression.

Results:

The proportions of individuals (N = 2845) in categories i to vii were 40.0% (n = 1139), 14.0% (n = 396), 4.5% (n = 129), 4.0% (n = 114), 1.2% (n = 34), 7.7% (n = 220), and 28.6% (n = 813), respectively. Severity of hearing impairment was the only factor predictive of all the categories of hearing health-seeking that could be modeled. Other correlates predictive of at least one category of hearing health-seeking included sex, age, self-reported heath, participation in social activities, and cognitive function.

Conclusions:

For the first time, it was shown that 40.0% of people with an audiometrically identified probable hearing impairment did not report hearing difficulties. Each of the five categories of hearing health-seeking that could be modeled had different drivers and consequently, interventions likely should vary depending on the category of hearing health-seeking.

Relationship between cigarette smoking and hearing loss in China: A cross-sectional study in Zhejiang province

INTRODUCTION

Hearing loss and cigarette smoking are major challenges that affect public health in China. Revealing the effect of smoking on hearing loss in the Chinese general population is critical for hearing health protection. We investigated the relationship between smoking status and hearing loss in China, especially in stratified sex and age groups.

METHODS

A cross-sectional study was conducted on 4685 individuals aged 20– 80 years in Zhejiang province from 2016 to 2018, with audiometric testing for hearing loss and a structured questionnaire for collecting smoking status and covariates. Logistic regression was used to estimate the association between smoking and hearing loss.

RESULTS

Cigarette smoking was not significantly associated with hearing loss in females and young males. In middle-aged males, after adjusting for covariates, current smokers and past smokers had a significantly higher prevalence of speech-frequency loss (OR=1.65; 95% CI: 1.17–2.33 and OR=1.88; 95% CI: 1.11–3.17; respectively) and high-frequency hearing loss (OR=2.01; 95% CI: 1.43–2.84 and OR=2.64; 95% CI: 1.50–4.66; respectively). In older males, only past smokers had a significantly higher prevalence of speech-frequency hearing loss than never smokers (OR=2.58; 95% CI: 1.38–4.85). Regarding middle-aged and older current smokers, a dose-dependent relationship between smoking intensity and hearing loss was found. Passive smoking was not significantly associated with an increased hearing loss risk in all the three male groups.

CONCLUSIONS

The relationship between cigarette smoking and hearing loss varied according to gender and age. Therefore, the interventions for smoking need to be tailored according to age in males.

Accessibility to Hearing Healthcare in Rural and Urban Populations of Alabama: Perspectives and A Preliminary Roadmap for Addressing Inequalities

Hearing loss is a growing public health concern and has been associated with poor cardiovascular health, diabetes, increased social isolation and poor cognitive functioning. Addressing this issue, especially in rural communities, will require increased awareness of hearing loss and its link to emotional and physical well-being. The purpose of this study was to understand the challenges that those with hearing loss living in rural and urban communities experience and to examine the feasibility of using primary care physicians to assist with improving access to hearing healthcare in rural communities. One hundred thirty-four participants were recruited from rural and urban counties in West Central and South Alabama. All participants completed a hearing evaluation and a Healthcare and Hearing Healthcare Accessibility Questionnaire. Over half of the adults in the study with hearing loss did not have access to hearing healthcare because of distance to a hearing healthcare professional. Other reasons for participants not having access to hearing healthcare included financial constraints, lack of awareness of having a hearing loss, lack of time to see a hearing healthcare provider, and not knowing how to access a provider. Results, however, revealed that most adults in the study had access to a primary care professional. The primary care provider, therefore, could be a valuable resource for the dissemination of information related to hearing healthcare. Collaborative work with primary care providers will help to develop and expand hearing healthcare awareness, research and services provided through the Here Hear Alabama project, a rural outreach initiative in West Central and South Alabama.

An Automated Speech-in-Noise Test for Remote Testing: Development and Preliminary Evaluation

Purpose The aim of this study was to develop and evaluate a novel, automated speech-in-noise test viable for widespread in situ and remote screening. Method Vowel-consonant-vowel sounds in a multiple-choice consonant discrimination task were used. Recordings from a professional male native English speaker were used. A novel adaptive staircase procedure was developed, based on the estimated intelligibility of stimuli rather than on theoretical binomial models. Test performance was assessed in a population of 26 young adults (YAs) with normal hearing and in 72 unscreened adults (UAs), including native and nonnative English listeners. Results The proposed test provided accurate estimates of the speech recognition threshold (SRT) compared to a conventional adaptive procedure. Consistent outcomes were observed in YAs in test/retest and in controlled/uncontrolled conditions and in UAs in native and nonnative listeners. The SRT increased with increasing age, hearing loss, and self-reported hearing handicap in UAs. Test duration was similar in YAs and UAs irrespective of age and hearing loss. The test-retest repeatability of SRTs was high (Pearson correlation coefficient = .84), and the pass/fail outcomes of the test were reliable in repeated measures (Cohen's κ = .8). The test was accurate in identifying ears with pure-tone thresholds > 25 dB HL (accuracy = 0.82). Conclusion This study demonstrated the viability of the proposed test in subjects of varying language in terms of accuracy, reliability, and short test time. Further research is needed to validate the test in a larger population across a wider range of languages and hearing loss and to identify optimal classification criteria for screening purposes.

Hearing Aid Prevalence and Factors Related to Use Among Older Adults From the Hispanic Community Health Study/Study of Latinos

Importance

Hearing loss is highly prevalent in the rapidly growing and aging Hispanic/Latino population in the United States. However, little is known or understood about hearing aid use among US adults from Hispanic/Latino backgrounds.

Objective

To describe hearing aid prevalence and factors associated with hearing aid use among US adults of Hispanic/Latino backgrounds.

Design, Setting, and Participants

Cross-sectional data were collected between 2008 and 2011 from 4 field centers (Bronx, New York; Chicago, Illinois; Miami, Florida; and San Diego, California) as part of the multisite Hispanic Community Health Study/Study of Latinos. Included individuals were adults aged 45 to 76 years with hearing loss (pure-tone average ≥25 dB HL) from randomly selected households in the 4 field centers and were from self-reported Hispanic/Latino backgrounds, including Central American, Cuban, Dominican, Mexican, Puerto Rican, South American, and mixed or other backgrounds. Analysis, including age- and background-weighted prevalence estimates and multivariate logistic regression using survey methodology, was conducted from 2017 to 2018.

Main Outcomes and Measures

The primary outcome of interest was self-reported hearing aid use. The a priori hypothesis was that hearing aid prevalence estimates among included Hispanic/Latino adults would be less than recently published estimates of the general US population, and that poorer hearing, higher perceived need, older age, and higher acculturation would be associated with hearing aid use.

Results

Of 1898 individuals with hearing loss, 1064 (56.1%) were men, and the mean (SE) age was 60.3 (0.3) years. A total of 87 (4.6%) included individuals reported hearing aid use. Increased odds of self-reported use was associated with poorer measured hearing (odds ratio [OR], 1.06; 95% CI, 1.03-1.09), higher Hearing Handicap Inventory-Screening scores (OR, 1.06; 95% CI, 1.03-1.08), access to health insurance coverage (OR, 2.30; 95% CI, 1.20-4.37), and place of residence (OR, 2.42; 95% CI, 1.17-5.02) in an adjusted logistic regression model.

Conclusions and Relevance

Findings revealed underuse of hearing aids among adults from Hispanic/Latino backgrounds. A primary factor related to use was lack of health insurance, which suggests that access influenced hearing aid use. Changes to policy and clinical service provision are needed to increase hearing aid use among aging Hispanic/Latino adults in the United States.

Self-Perceived Hearing Status Creates an Unrealized Barrier to Hearing Healthcare Utilization

OBJECTIVE

To examine sociodemographic and audiometric factors associated with hearing aid (HA) uptake in adults with hearing loss (HL), and to investigate the role of self-perceived hearing status on pursuit of hearing treatment. The relationship between self-perceived hearing status and HA adoption has not been reported in a nationally representative sample of United States (US) adults.

STUDY DESIGN

Cross-sectional analysis of nationwide household health survey.

METHODS

Audiometric and questionnaire data from the 2005 to 2012 National Health and Nutrition Examination Survey cycles were used to examine trends in untreated HL and HA adoption in US adults. Adjusted odds ratios for HA adoption were calculated for individuals with measured HL.

RESULTS

Of 5230 respondents, 26.1% had measurable HL, of which only 16.0% correctly self-identified their hearing status, and only 17.7% used an HA. Age, higher education, severe hearing impairments, and recent hearing evaluations, were positively associated with HA adoption.

CONCLUSION

Hearing loss is a global public health concern placing significant economic burden on both the individual and society. Self-reported hearing status is not a reliable indicator for HL, and measured HL is not correlated with increased rates of treatment. Recent hearing evaluation is positively associated with increased rates of treatment. Routine hearing assessment will help to better identify those with HL and improve access to hearing treatment.

A Novel Method for Classifying Hearing Impairment in Epidemiological Studies of Aging: The Wisconsin Age-Related Hearing Impairment Classification Scale

Purpose Longitudinal population-based cohort data were used to develop a standardized classification system for age-related hearing impairment using thresholds for frequencies (0.5-8 kHz) typically measured in cohort studies. Method Audiometric testing data collected in the Epidemiology of Hearing Loss Study from participants (n = 1,369) with four visits (1993-1995, 1998-2000, 2003-2005, and 2009-2010) were included (10,952 audiograms). Cluster analyses (Wald's method) were used to identify audiometric patterns. Maximum allowable threshold values were defined for each cluster to create an ordered scale. Progression was defined as a two-step change. Results An eight-step scale was developed to capture audiogram shape and severity of hearing impairment. Of the 1,094 participants classified as having normal hearing based on a pure-tone average, only 25% (n = 277) were classified as Level 1 (all thresholds ≤ 20 dB HL) on the new scale, whereas 17% (n = 182) were Levels 4-6. During the 16-year follow-up, 64.9% of those at Level 1 progressed. There was little regression using this scale. Conclusions This is the first scale developed from population-based longitudinal cohort data to capture audiogram shape across time. This simple, standardized scale is easy to apply, reduces misclassification of normal hearing, and may be a useful method for identifying risk factors for early, preclinical, age-related changes in hearing.

Correlates of Hearing Aid Use in UK Adults: Self-Reported Hearing Difficulties, Social Participation, Living Situation, Health, and Demographics

OBJECTIVES

Hearing impairment is ranked fifth globally for years lived with disability, yet hearing aid use is low among individuals with a hearing impairment. Identifying correlates of hearing aid use would be helpful in developing interventions to promote use. To date, however, no studies have investigated a wide range of variables, this has limited intervention development. The aim of the present study was to identify correlates of hearing aid use in adults in the United Kingdom with a hearing impairment. To address limitations in previous studies, we used a cross-sectional analysis to model a wide range of potential correlates simultaneously to provide better evidence to aid intervention development.

DESIGN

The research was conducted using the UK Biobank Resource. A cross-sectional analysis of hearing aid use was conducted on 18,730 participants aged 40 to 69 years old with poor hearing, based on performance on the Digit Triplet test.

RESULTS

Nine percent of adults with poor hearing in the cross-sectional sample reported using a hearing aid. The strongest correlate of hearing aid use was self-reported hearing difficulties (odds ratio [OR] = 110.69 [95% confidence interval {CI} = 65.12 to 188.16]). Individuals who were older were more likely to use a hearing aid: for each additional year of age, individuals were 5% more likely to use a hearing aid (95% CI = 1.04 to 1.06). People with tinnitus (OR = 1.43 [95% CI = 1.26 to 1.63]) and people with a chronic illness (OR = 1.97 [95% CI = 1.71 to 2.28]) were more likely to use a hearing aid. Those who reported an ethnic minority background (OR = 0.53 [95% CI = 0.39 to 0.72]) and those who lived alone (OR = 0.80 [95% CI = 0.68 to 0.94]) were less likely to use a hearing aid.

CONCLUSIONS

Interventions to promote hearing aid use need to focus on addressing reasons for the perception of hearing difficulties and how to promote hearing aid use. Interventions to promote hearing aid use may need to target demographic groups that are particularly unlikely to use hearing aids, including younger adults, those who live alone and those from ethnic minority backgrounds.

Development of a hearing help-seeking questionnaire based on the theory of planned behavior

OBJECTIVE

Our objective was to develop and assess a questionnaire measuring the constructs of the theory of planned behaviour (TPB) regarding older adults' behaviours towards seeking a hearing test.

DESIGN

Older adults who failed a hearing screening completed a newly developed Theory of Planned Behavior-Hearing Help Seeking (TPB-HHS) questionnaire. A principal components analysis (PCA) examined the factor structure of the questionnaire, and a reliability analysis determined the internal consistency of the factors. An examination of six-month follow-up data determined whether the questionnaire differentiated between individuals who did and did not seek out a hearing test by comparing their TPB-HHS scores.

STUDY SAMPLE

Participants were 407 adults aged 50 to 89 recruited at community hearing screenings.

RESULTS

PCA and reliability analyses resulted in a 4-factor, 18 item questionnaire. Three of four factors demonstrated acceptable internal consistency. The TPB-HHS explained 60.18% of the variance and factors were interpreted to be measuring the constructs of Intentions, Perceived Behavioral Control, Attitudes, and Subjective Norms. Individuals who sought a hearing test scored significantly higher on the Intentions, Perceived Behavioral Control, and Attitudes scales than those who did not.

CONCLUSIONS

The TPB-HHS provides insight into underlying psychological mechanisms that drive behaviours related to hearing help-seeking in older adults.

The Chronic Care Model and Chronic Condition Self-Management: An Introduction for Audiologists

Hearing health care is biomedically focused, device-centered, and clinician-led. There is emerging evidence that these characteristics-all of which are hallmarks of a health care system designed to address acute, rather than chronic, conditions-may contribute to low rates of help-seeking and hearing rehabilitation uptake among adults with hearing loss. In this review, we introduce audiologists to the Chronic Care Model, an organizational framework that describes best-practice clinical care for chronic conditions, and suggest that it may be a viable model for hearing health care to adopt. We further introduce the concept of chronic condition self-management, a key component of chronic care that refers to the knowledge and skills patients use to manage the effects of a chronic condition on all aspects of daily life. Drawing on the chronic condition evidence base, we demonstrate a link between the provision of effective self-management support and improved clinical outcomes and discuss validated methods with which clinicians can support the acquisition and application of self-management skills in their patients. We examine the extent to which elements of chronic condition self-management have been integrated into clinical practice in audiology and suggest directions for further research in this area.

Enhancing Screening Systems to Facilitate Hearing-Healthcare Access: A Qualitative Study

BACKGROUND

Although hearing loss is a common health issue, hearing healthcare (HHC) is poorly accessed. Screening to identify hearing loss is an important part of HHC access, specifically for those who screen positive for hearing loss and would benefit from seeing a HHC provider. New technologies can be automated to provide information and recommendations that are tailored to the needs of individual users, potentially enhancing rates of HHC access after positive screens. A greater understanding of the facilitators of postscreening HHC access that could be leveraged in such systems is needed.

PURPOSE

The purpose of this project was to identify facilitators of postscreening HHC access that can be used in automated screening systems.

RESEARCH DESIGN

This qualitative study used focus groups (FGs) to understand perceived barriers, perceived benefits, and potential cues to action, as informed by the Health Belief Model, for accessing HHC after use of automated hearing screening systems.

STUDY SAMPLE

Fifty individuals participated in one of seven FGs. FGs were conducted separately with three types of stakeholders: four FGs included adults who reported some degree of perceived hearing loss and had recently completed a hearing screening; two FGs included adults who had recently sought HHC for the first time because of hearing loss; and one FG involved significant others/family members of individuals with hearing loss.

DATA COLLECTION AND ANALYSIS

FGs were 60-90 minutes in length and were led by a trained facilitator following a discussion guide. A research audiologist was present at each FG and served as a notetaker. FGs were recorded and transcribed by research team members, and transcripts were then coded in an iterative process by multiple team members. Qualitative content analysis was used to reduce data and to identify salient themes and subthemes, following an inductive approach. We focused on identifying themes that were related to facilitators of HHC access after positive screens for hearing loss and, separately, potential enhancements to automated hearing screening systems that would leverage these facilitators to improve HHC access.

RESULTS

We identified five key themes related to HHC access after a positive screen for hearing loss, along with ideas for enhancing automated hearing screening systems based on these themes. The themes included knowledge, trust, access, quality of life, and interpersonal influence.

CONCLUSIONS

The results of our work help inform the development of innovative hearing screening systems that can be automated to leverage individual facilitators of HHC access.

The Potential in Preparing Community Health Workers to Address Hearing Loss

BACKGROUND

In underserved areas, it is crucial to investigate ways of increasing access to hearing health care. The community health worker (CHW) is a model that has been applied to increase access in various health arenas. This article proposes further investigation into the application of this model to audiology.

PURPOSE

To assess the feasibility of training CHWs about hearing loss as a possible approach to increase accessibility of hearing health support services in an underserved area.

RESEARCH DESIGN

A specialized three-phase training process for CHWs was developed, implemented, and evaluated by audiologists and public health researchers. The training process included (1) focus groups with CHWs and residents from the community to raise awareness of hearing loss among CHWs and the community; (2) a 3-hr workshop training to introduce basic topics to prepare CHWs to identify signs of hearing loss among community members and use effective communication strategies; and (3) a 24-hr multisession, interactive training >6 weeks for CHWs who would become facilitators of educational and peer-support groups for individuals with hearing loss and family members.

STUDY SAMPLE

Twelve Spanish-speaking local CHWs employed by a federally qualified health center participated in a focus group, twelve received the general training, and four individuals with prior experience as health educators received further in-person training as facilitators of peer-education groups on hearing loss and communication.

DATA COLLECTION AND ANALYSIS

Data was collected from each step of the three-phase training process. Thematic analysis was completed for the focus group data. Pre- and posttraining assessments and case study discussions were used to analyze results for the general workshop and the in-depth training sessions.

RESULTS

CHWs increased their knowledge base and confidence in effective communication strategies and developed skills in facilitating hearing education and peer-support groups. Through case study practice, CHWs demonstrated competencies and applied their learning to specific situations related to effective communication with hearing loss, family support, availability of assistive technology, use of hearing protection, and making referrals for hearing health care. Needs were identified for ongoing training in the area of use of assistive technology and addressing situations of more severe hearing loss and its effects.

CONCLUSIONS

Initial results suggest it is feasible to train CHWs to engage community members regarding hearing loss and facilitate culturally relevant peer-health education and peer-support groups for individuals with hearing loss and their family members. In efforts to increase access to audiological services in rural or underserved communities, application of the CHW model with a partnership of audiologists deserves further consideration as a viable approach.

Hearing Loss in the Elderly

Presbycusis, or age-related hearing loss (ARHL), is the result of physiologic and pathologic changes associated with advancing age. ARHL presents typically with a high-frequency hearing loss, which contributes to greater trouble hearing consonants within words. Consonants convey the bulk of meaning within a word, and this loss of linguistic information results in complaints associated with ARHL. Hearing aids and cochlear implants significantly improve the lives of older adults with hearing loss, in particular, those with depression and dementia. Successful current research in gene therapy, pharmacotherapy, and stems cells holds the promise of being able to restore native cochlear function.

Hearing aids: indications, technology, adaptation, and quality control

Hearing loss can be caused by a number of different pathological conditions. Some of them can be successfully treated, mainly by surgery, depending on the individual's disease process. However, the treatment of chronic sensorineural hearing loss with damaged cochlear structures usually needs hearing rehabilitation by means of technical amplification. During the last two decades tremendous improvements in hearing aid technology led to a higher quality of the hearing rehabilitation process. For example, due to sophisticated signal processing acoustic feedback could be reduced and hence open fitting options are available even for more subjects with higher degrees of hearing loss. In particular for high-frequency hearing loss, the use of open fitting is an option. Both the users' acceptance and the perceived sound quality were significantly increased by open fittings. However, we are still faced with a low level of readiness in many hearing impaired subjects to accept acoustic amplification. Since ENT specialists play a key-role in hearing aid provision, they should promote early hearing aid rehabilitation and include this in the counselling even in subjects with mild and moderate hearing loss. Recent investigations demonstrated the benefit of early hearing aid use in this group of patients since this may help to reduce subsequent damages as auditory deprivation, social isolation, development of dementia, and cognitive decline. For subjects with tinnitus, hearing aids may also support masking by environmental sounds and enhance cortical inhibition. The present paper describes the latest developments of hearing aid technology and the current state of the art for amplification modalities. Implications for both hearing aid indication and provision are discussed.

Declining Prevalence of Hearing Loss in US Adults Aged 20 to 69 Years

Importance

As the US population ages, effective health care planning requires understanding the changes in prevalence of hearing loss.

Objective

To determine if age- and sex-specific prevalence of adult hearing loss has changed during the past decade.

Design, Setting, and Participants

We analyzed audiometric data from adults aged 20 to 69 years from the 2011-2012 cycle of the US National Health and Nutrition Examination Survey, a cross-sectional, nationally representative interview and examination survey of the civilian, noninstitutionalized population, and compared them with data from the 1999-2004 cycles. Logistic regression was used to examine unadjusted, age- and sex-adjusted, and multivariable-adjusted associations with demographic, noise exposure, and cardiovascular risk factors. Data analysis was performed from April 28 to June 3, 2016.

Interventions

Audiometry and questionnaires.

Main Outcomes and Measures

Speech-frequency hearing impairment (HI) defined by pure-tone average of thresholds at 4 frequencies (0.5, 1, 2, and 4 kHz) greater than 25 decibels hearing level (HL), and high-frequency HI defined by pure-tone average of thresholds at 3 frequencies (3, 4, and 6 kHz) greater than 25 decibels HL.

Results

Based on 3831 participants with complete threshold measurements (1953 men and 1878 women; mean [SD] age, 43.6 [14.4] years), the 2011-2012 nationally weighted adult prevalence of unilateral and bilateral speech-frequency HI was 14.1% (27.7 million) compared with 15.9% (28.0 million) for the 1999-2004 cycles; after adjustment for age and sex, the difference was significant (odds ratio [OR], 0.70; 95% CI, 0.56-0.86). Men had nearly twice the prevalence of speech-frequency HI (18.6% [17.8 million]) as women (9.6% [9.7 million]). For individuals aged 60 to 69 years, speech-frequency HI prevalence was 39.3% (95% CI, 30.7%-48.7%). In adjusted multivariable analyses for bilateral speech-frequency HI, age was the major risk factor (60-69 years: OR, 39.5; 95% CI, 10.5-149.4); however, male sex (OR, 1.8; 95% CI, 1.1-3.0), non-Hispanic white (OR, 2.3; 95% CI, 1.3-3.9) and non-Hispanic Asian race/ethnicity (OR, 2.1; 95% CI, 1.1-4.2), lower educational level (less than high school: OR, 4.2; 95% CI, 2.1-8.5), and heavy use of firearms (≥1000 rounds fired: OR, 1.8; 95% CI, 1.1-3.0) were also significant risk factors. Additional associations for high-frequency HI were Mexican-American (OR, 2.0; 95% CI, 1.3-3.1) and other Hispanic race/ethnicity (OR, 2.4; 95% CI, 1.4-4.0) and the combination of loud and very loud noise exposure occupationally and outside of work (OR, 2.4; 95% CI, 1.4-4.2).

Conclusions and Relevance

Adult hearing loss is common and associated with age, other demographic factors (sex, race/ethnicity, and educational level), and noise exposure. Age- and sex-specific prevalence of HI continues to decline. Despite the benefit of delayed onset of HI, hearing health care needs will increase as the US population grows and ages.

Hearing loss and use of health services: a population-based cross-sectional study among Finnish older adults

Background

Older adults with hearing difficulties face problems of communication which may lead to underuse of health services. This study investigated the association of hearing loss and self-reported hearing difficulty with the use of health services and unmet health care needs in older adults.

Methods

Data on persons aged 65 and older (n = 2144) drawn from a population-based study, Health 2000, were analyzed. Hearing loss was determined with screening audiometry (n = 1680). Structured face-to-face interviews were used to assess self-reported hearing difficulty (n = 1962), use of health services (physician and nurse visits, health examinations, mental health services, physical therapy, health promotion groups, vision test, hearing test, mammography, PSA test) and perceived unmet health care needs. Multivariable logistic regression analyses were used.

Results

After adjusting for socio-economic and health-related confounders, persons with hearing loss (hearing level of better ear 0.5–2 kHz > 40 dB) were more likely to have used mental health services than those with non-impaired hearing (OR = 3.2, 95 % CI 1.3–7.9). Self-reported hearing difficulty was also associated with higher odds for mental health service use (OR = 2.1 95 % CI 1.2–3.5). Hearing was not associated with use of the other health services studied, except presenting for a hearing test. Persons with self-reported hearing difficulty were more likely to perceive unmet health care needs than those without hearing difficulty (OR = 1.7, 95 % CI 1.4–2.1).

Conclusions

Older adults with hearing loss or self-reported hearing difficulty are as likely to use most health services as those without hearing loss. However, self-reported hearing difficulty is associated with experiencing unmet health care needs. Adequate health services should be ensured for older adults with hearing difficulties.

Access to Health Care and Hearing Evaluation in US Adults

Objectives:

To explore self-reported hearing testing access for adults in a nationally representative survey.

Methods:

Demographic and audiologic adult survey respondent variables in the National Health and Nutrition Examination Survey (NHANES) database 2011-2012 cohort were examined. Logistic regression was used to determine odds ratios (OR) and 95% confidence intervals (CI).

Results:

In all, 5864 adult respondents were analyzed. Two-thirds (65.6%) of respondents reported having hearing tested 10 or more years ago or never tested at all. Male gender (OR = 2.27; 95% CI, 1.31-3.94), having a health care visit less than 3 years ago (OR = 8.19; 95% CI, 2.09-32.2), and having health insurance (OR = 1.73; 95% CI, 1.08-2.77) were significantly associated with respondents reporting having a hearing test less than 10 years ago. Mexican American race (OR = 0.41; 95% CI, 0.20-0.83) and respondent age 40 to 59 (OR = 0.52; 95% CI, 0.33-0.81) were significantly associated with respondents reporting having a hearing test 10 or more years prior or never.

Conclusion:

A significant proportion of the adult population reports having hearing tested 10 or more years prior or never at all. Effort will be required to identify adults who have hearing loss and may benefit from auditory rehabilitation such as hearing aids or the cochlear implant.

How sociodemographic and hearing related factors were associated with use of hearing aid in a population-based study: The HUNT Study

Background

The purpose was to study hearing aid (HA) use in persons 65 years and older, and to investigate how socioeconomic and hearing related factors were associated to use of HA.

Method

This study included 11,602 persons (65 years and above) from the second Nord-Trøndelag Health Study (HUNT2) and the integrated North-Trøndelag hearing loss study (NTHLS) in 1995–1997. Audiometry was taken of all participants. Missing information about use of HA in possible users of HA existed in data from 1103 (9.5 %) of the participants. Effects of sociodemographic variables, low, medium and high frequency hearing thresholds and being bothered by their hearing were explored in men and women, adjusting the effects for each other. Cross tabulations and logistic regression analyses were used.

Results

In all, 14 % (1472 of 10,499) were users of HA, but 62 % had a mean hearing impairment (HI) based on 0.5, 1, 2, 4 kHz over both ears >25 dB. Use of HA was associated with higher education. Adjusting for all covariates and hearing variables, each 10 dB medium frequency threshold shift increased the chance of HA-use by a factor of two-three in both men and women. Having reported being bothered by hearing loss additionally increased the chance around sevenfold. Low frequency hearing thresholds were not associated with HA-use in women. In men, low frequency hearing thresholds up to 50 dB increased odds for use of HA, but low frequency hearing thresholds ≥ 70 dB decreased odds for use of HA. Men living with a spouse had higher odds for using HA compared to men without a spouse. For women there is no difference between those with and without spouse in use of HA. Men and women without spouse did not differ in their use of HA.

Conclusions

About two third of 65 years and older participants had a HI higher than 25 dB, but only one seventh used HA. Use of HA was associated with higher than basic education. Men without a spouse were less likely to use HA compared to men with a spouse.

Racial/Ethnic and Socioeconomic Disparities in Hearing Health Care Among Older Americans

OBJECTIVE

Hearing impairment is highly prevalent, but little is known about hearing health care among older minority adults.

METHOD

We analyzed nationally representative, cross-sectional data from 1,544 older adults ≥ 70 years with audiometry and hearing care data from the 2005-2006 and 2009-2010 National Health and Nutritional Examination Surveys.

RESULTS

After adjusting for age and speech frequency pure tone average, Blacks (odds ratio [OR] = 1.68, vs. Whites) and those with greater education (OR = 1.63, ≥ college vs. < high school) were more likely to report recent hearing testing, while White older adults and those with greater socioeconomic status were more likely to report regular hearing aid use (all ps < .05). Based on a multivariate analysis, Blacks were not more likely than Whites to use hearing aids despite being more likely to have had recent hearing testing.

DISCUSSION

Racial/ethnic and socioeconomic disparities exist in hearing health care and represent critical areas for research and intervention.

Self-Reported Hearing Difficulties Among Adults With Normal Audiograms: The Beaver Dam Offspring Study

OBJECTIVE

Clinicians encounter patients who report experiencing hearing difficulty (HD) even when audiometric thresholds fall within normal limits. When there is no evidence of audiometric hearing loss, it generates debate over possible biomedical and psychosocial etiologies. It is possible that self-reported HDs relate to variables within and/or outside the scope of audiology. The purpose of this study is to identify how often, on a population basis, people with normal audiometric thresholds self-report HD and to identify factors associated with such HDs.

DESIGN

This was a cross-sectional investigation of participants in the Beaver Dam Offspring Study. HD was defined as a self-reported HD on a four-item scale despite having pure-tone audiometric thresholds within normal limits (<20 dB HL0.5, 1, 2, 3, 4, 6, 8 kHz bilaterally, at each frequency). Distortion product otoacoustic emissions and word-recognition performance in quiet and with competing messages were also analyzed. In addition to hearing assessments, relevant factors such as sociodemographic and lifestyle factors, environmental exposures, medical history, health-related quality of life, and symptoms of neurological disorders were also examined as possible risk factors. The Center for Epidemiological Studies-Depression was used to probe symptoms associated with depression, and the Medical Outcomes Study Short-Form 36 mental score was used to quantify psychological stress and social and role disability due to emotional problems. The Visual Function Questionnaire-25 and contrast sensitivity test were used to query vision difficulties.

RESULTS

Of the 2783 participants, 686 participants had normal audiometric thresholds. An additional grouping variable was created based on the available scores of HD (four self-report questions), which reduced the total dataset to n = 682 (age range, 21-67 years). The percentage of individuals with normal audiometric thresholds who self-reported HD was 12.0% (82 of 682). The prevalence in the entire cohort was therefore 2.9% (82 of 2783). Performance on audiological tests (distortion product otoacoustic emissions and word-recognition tests) did not differ between the group self-reporting HD and the group reporting no HD. A multivariable model controlling for age and sex identified the following risk factors for HD: lower incomes (odds ratio [OR] $50,000+ = 0.55, 95% confidence interval [CI] = 0.30-1.00), noise exposure through loud hobbies (OR = 1.48, 95% CI = 1.15-1.90), or firearms (OR = 2.07, 95% CI = 1.04-4.16). People reporting HD were more likely to have seen a doctor for hearing loss (OR = 12.93, 95% CI = 3.86-43.33) and report symptoms associated with depression (Center for Epidemiological Studies-Depression [OR = 2.39, 95% CI = 1.03-5.54]), vision difficulties (Visual Function Questionnaire-25 [OR = 0.93, 95% CI = 0.89-0.97]), and neuropathy (e.g., numbness, tingling, and loss of sensation [OR = 1.98, 95% CI = 1.14-3.44]).

CONCLUSIONS

The authors used a population approach to identify the prevalence and risk factors associated with self-reported HD among people who perform within normal limits on common clinical tests of auditory function. The percentage of individuals with normal audiometric thresholds who self-reported HD was 12.0%, resulting in an overall prevalence of 2.9%. Auditory and nonauditory risk factors were identified, therefore suggesting that future directions aimed at assessing, preventing, and managing these types of HDs might benefit from information outside the traditional scope of audiology.

Hearing Impairment Prevalence and Associated Risk Factors in the Hispanic Community Health Study/Study of Latinos

IMPORTANCE

Hearing impairment is common in adults, but few studies have addressed it in the US Hispanic/Latino population.

OBJECTIVE

To determine the prevalence of hearing impairment among US Hispanic/Latino adults of diverse backgrounds and determine associations with potential risk factors.

DESIGN, SETTING, AND PARTICIPANTS

The Hispanic Community Health Study/Study of Latinos (HCHS/SOL) is a population-based sample of Hispanics/Latinos in four US communities (Bronx, New York; Chicago, Illinois; Miami, Florida; and San Diego, California). Examinations were conducted from 2008 through 2011. The HCHS/SOL examined 16,415 self-identified Hispanic/Latino persons aged 18 to 74 years recruited from randomly selected households using a stratified 2-stage area probability sample design based on census block groups and households within block groups.

MAIN OUTCOMES AND MEASURES

Hearing thresholds were measured by pure-tone audiometry. Hearing impairment was defined as a pure-tone average (PTA) of thresholds at 0.5, 1, 2, and 4 kHz greater than 25 dB hearing level. Bilateral hearing impairment required a PTA greater than 25 dB hearing level in both ears. Multivariable analyses included adjustments for sociodemographic and lifestyle variables, body mass index, and medical conditions.

RESULTS

The prevalence of hearing impairment was 15.06% (SE, 0.44%) overall, and 8.24% (SE, 0.33%) had bilateral hearing impairment. The prevalence of hearing impairment was higher among people 45 years and older, ranging by Hispanic/Latino background from 29.35% to 41.20% among men and 17.89% to 32.11% among women. The multivariable-adjusted odds of hearing impairment was greater for participants of Puerto Rican background compared with Mexican background (odds ratio [OR], 1.57 [95% CI, 1.10-2.25]). The odds of hearing impairment were lower with more education (OR, 0.71 [95% CI, 0.59-0.86] for at least high school) and higher income (OR, 0.58 [95% CI, 0.36-0.92] for >$75,000 vs ≤$10,000). Noise exposure (OR, 1.35 [95% CI, 1.07-1.70]), diabetes (OR, 1.57 [95% CI, 1.27-1.94]), and prediabetes (OR, 1.37 [95% CI, 1.12-1.67]) were associated with hearing impairment.

CONCLUSIONS AND RELEVANCE

Hearing impairment is a common problem for older Hispanics/Latinos in these communities and is associated with socioeconomic factors, noise exposure, and abnormal glucose metabolism. Longitudinal studies are needed to determine whether these factors are involved in the etiology of hearing impairment and to identify ways to prevent or delay age-related changes in hearing.

Sex-specific predictors of hearing-aid use in older persons: The age, gene/environment susceptibility - Reykjavik study

OBJECTIVE

We estimate the prevalence of hearing-aid use in Iceland and identify sex-specific factors associated with use.

DESIGN

Population-based cohort study.

STUDY SAMPLE

A total of 5172 age, gene/environment susceptibility - Reykjavik study (AGES-RS) participants, aged 67 to 96 years (mean age 76.5 years), who completed air-conduction and pure-tone audiometry.

RESULTS

Hearing-aid use was reported by 23.0% of men and 15.9% of women in the cohort, although among participants with at least moderate hearing loss in the better ear (pure-tone average [PTA] of thresholds at 0.5, 1, 2, and 4 kHz ≥ 35 dB hearing level [HL]) it was 49.9% and did not differ by sex. Self-reported hearing loss was the strongest predictor of hearing-aid use in men [OR: 2.68 (95% CI: 1.77, 4.08)] and women [OR: 3.07 (95% CI: 1.94, 4.86)], followed by hearing loss severity based on audiometry. Having diabetes or osteoarthritis were significant positive predictors of use in men, whereas greater physical activity and unimpaired cognitive status were important in women.

CONCLUSIONS

Hearing-aid use was comparable in Icelandic men and women with moderate or greater hearing loss. Self-recognition of hearing loss was the factor most predictive of hearing-aid use; other influential factors differed for men and women.

Subclinical atherosclerosis and increased risk of hearing impairment

OBJECTIVE

The study's purpose was to test if subclinical atherosclerosis was associated with the risk of developing HI in a large cohort of middle-aged participants.

METHODS

Study subjects were members of the Beaver Dam Offspring Study (BOSS), a longitudinal study of adult children of participants in the population-based Epidemiology of Hearing Loss Study (1993-present). BOSS examinations took place in 2005-2008 (baseline) and 2010-2013 (5-year follow-up). The 5-year incidence of hearing impairment was defined as a pure-tone average (PTA) of thresholds at 0.5, 1, 2 and 4 kHz > 25 dB Hearing Level (dB HL) in either ear at follow-up among participants at risk (baseline PTA in both ears < = 25 dB HL; n = 2436, mean age = 47.7 years). Atherosclerosis was measured as the mean carotid intima-media thickness and the presence of carotid artery plaque.

RESULTS

Among the 1984 participants at-risk with a follow-up audiometric examination, the 5-year incidence of hearing impairment was 8.3% (95% Confidence Interval (C.I.) 7.1, 9.5). With multivariable adjustment, carotid intima-media thickness was positively associated with hearing impairment incidence (Relative Risk (RR) = 1.14 per 0.1 mm, 95% C.I. 1.04, 1.24). The number of sites (0-6) with plaque was also positively associated with the incidence of impairment (RR = 1.16 per site, 95% C.I. 1.01, 1.32).

CONCLUSION

Atherosclerosis was associated with the 5-year incidence of hearing impairment in this predominantly middle-aged cohort. Interventions targeting atherosclerosis prevention may help to prevent or delay the onset of hearing impairment.

Hearing loss in an aging American population: extent, impact, and management

Despite contributing substantially to disability in the United States, age-related hearing loss is an underappreciated public health concern. Loss of hearing sensitivity has been documented in two-thirds of adults aged 70 years and older and has been associated with communication difficulties, lower health-related quality of life, and decreased physical and cognitive function. Management strategies for age-related hearing loss are costly, yet the indirect costs due to lost productivity among people with communication difficulties are also substantial and likely to grow. Hearing aids can improve health-related quality of life, but the majority of people with documented hearing loss do not report using them. Uncovering effective means to improve the utilization of hearing health care services is essential for meeting the hearing health care demands of our aging population. The importance of hearing for general well-being warrants an effort to enhance awareness among the general population of the indications of hearing loss and options for assistance.
