Project description:IntroductionHearing loss is common in ageing populations, but thorough investigation of factors associated with objective hearing loss in otherwise healthy, community-dwelling older individuals is rare. We examined prevalence of age-related hearing loss (ARHL) in healthy, community-dwelling older adults, and determined whether sociodemographic, lifestyle, or health factors associate with hearing thresholds. Audiometry assessment was investigated with self-reports of hearing loss and hearing handicap.MethodsAustralian participants (n = 1,260) of median age 73 years (IQR 71-76) joined ASPirin in Reducing Events in the Elderly (ASPREE)-Hearing, a sub-study of the ASPREE trial with exclusions including cognitive impairment, cardiovascular disease, independence-limiting physical disability, and uncontrolled hypertension. ASPREE collected demographics, anthropometrics, lifestyle, and health data. Audiometry measured better ear pure-tone average (PTA) across four frequencies (0.5-4 kHz) to establish hearing thresholds, categorised as normal or mild, moderate, and severe hearing loss. Questionnaires collected perceived hearing problems and noise exposure.ResultsARHL prevalence by audiometry was 49.7%, affecting men (59%) more than women (41%). A majority (54.5%) self-reported some hearing problems which mostly aligned with objective assessments; 45.6% self-reported a "little trouble" with hearing, while 35% had objective mild hearing loss; 8.3% reported having a "lot of trouble" hearing, while 13% had moderate hearing loss; and 0.6% reported being "deaf," while 2% demonstrated severe hearing loss. There was a significant association (p < 0.001) between self-reported hearing handicap and audiometric measures of hearing loss. In multivariate analysis of health, demographics, and lifestyle risk factors, only age, gender (men), and education years (<12) remained associated (p < 0.05) with hearing loss. Hearing thresholds were not associated with smoking, living situation, alcohol use, hypertension, diabetes, or chronic kidney disease.ConclusionARHL robustly assessed by audiometry is common among healthy older Australians with men more likely to have abnormal hearing thresholds than women. Hearing loss was associated with fewer years of formal education, but not with a range of chronic conditions or alcohol use. Self-reported hearing loss correlates well with higher PTA hearing threshold levels in this healthy cohort where prevalence was lower than previously reported for the age group 70+ years. Hearing health education remains an important public health tool for this age. Targeting hearing in older patient health checks could be beneficial to mitigate the cognitive, social, and mental health consequences of ARHL, even if patients do not report a problem or handicap.

Project description:BackgroundPrevious studies have suggested that hearing loss, which is highly prevalent but undertreated in older adults, may be associated with gait and physical functioning. Determining if hearing loss is independently associated with gait speed is critical toward understanding whether hearing rehabilitative interventions could help mitigate declines in physical functioning in older adults.MethodsWe analyzed cross-sectional data from the 1999 to 2002 cycles of the National Health and Nutritional Examination Survey during which participants 50-69 years (n=1180) underwent hearing and gait speed assessments. Hearing was defined by a pure tone average of hearing thresholds at 0.5-4kHz tones in the better-hearing ear. Gait speed was obtained in a timed 20-ft (6.1m) walk. Linear and logistic regression models were used to examine the association between hearing loss and gait speed while adjusting for demographic and cardiovascular risk factors. Analyses incorporated sampling weights to yield results generalizable to the U.S. population.ResultsIn a model adjusted for demographic and cardiovascular risk factors, a hearing loss was associated with slower gait speed (-0.05m/s per 25dB of hearing loss [95% CI: -0.09 to -0.02]) and an increased odds of having a gait speed <1.0m/s (OR=2.0 per 25dB of hearing loss, 95% CI: 1.2-3.3). The reduction in gait speed associated with a 25dB hearing loss was equivalent to that associated with an age difference of approximately 12 years.ConclusionsGreater hearing loss is independently associated with slower gait speed. Further studies investigating the mechanistic basis of this association and whether hearing rehabilitative interventions could affect gait and physical functioning are needed.

Project description:ImportanceSeveral studies have examined the association between hearing loss (HL) and physical function, with inconsistent results. Few used pure-tone thresholds and considered possible confounders in the association.ObjectiveTo examine the association between hearing loss and impaired lower extremity function, frailty syndrome, and disability in older adults.Design, setting, and participantsThe Seniors-ENRICA-2 is a cohort study that was established in 2015-2017 in Spain. The present study was conducted from December 2015 to June 2017. Data were analyzed from January 2, 2021, to March 10, 2021. This cross-sectional analysis included 1644 community-dwelling individuals aged 65 years or older (range, 66-91 years) of both sexes. Participants had hearing threshold measurements and data on impaired lower extremity function, frailty syndrome, and disability.ExposuresHearing loss defined as pure-tone average greater than 40 dB HL in the better ear for standard frequency (0.5, 1, and 2 kHz), speech frequency (0.5, 1, 2, and 4 kHz), and high frequency (3, 4, and 8 kHz).Main outcomes and measuresImpaired lower extremity function was defined with the Short Physical Performance Battery; the frailty syndrome was defined as having at least 3 of the 5 criteria, including weakness, slow walking speed, low physical activity, exhaustion, and weight loss; and disability in instrumental activities of daily living (IADL) was evaluated with the Lawton and Brody scale.ResultsOf the 1644 participants, 831 were men (50.5%); mean (SD) age was 73.8 (4.3) years. The prevalence of moderate HL was 13.6% at speech frequency. After adjustment for age, sex, lifestyle, comorbidities, impaired cognition, and social isolation, HL in standard frequency was associated with impaired lower extremity function, with an odds ratio (OR) of 2.20 (95% CI, 1.25-3.88); the corresponding estimate for the frailty syndrome was 1.85 (95% CI, 0.98-3.49) and for the IADL disability, was 2.25 (95% CI, 1.29-3.94). When considering speech frequency pure-tone average, HL was also associated with impaired function (OR, 2.59; 95% CI, 1.57-4.28), frailty syndrome (OR, 1.85; 95% CI, 1.06-3.22), and IADL disability (OR, 2.18; 95% CI, 1.32-3.60).Conclusions and relevanceIn this cross-sectional analysis of data from the Seniors-ENRICA-2 cohort study, hearing loss was associated with impaired lower extremity function, frailty syndrome, and IADL disability. It may be useful to examine this association with the mechanisms elucidated in further studies.

Project description:ObjectivesThe goal of this study was to identify the effects of auditory deprivation (age-related hearing loss) and auditory stimulation (history of hearing aid use) on the neural registration of sound across two stimulus presentation conditions: (1) equal sound pressure level and (2) equal sensation level.DesignWe used a between-groups design, involving three groups of 14 older adults (n = 42; 62 to 84 years): (1) clinically defined normal hearing (≤25 dB from 250 to 8000 Hz, bilaterally), (2) bilateral mild-moderate/moderately severe sensorineural hearing loss who have never used hearing aids, and (3) bilateral mild-moderate/moderately severe sensorineural hearing loss who have worn bilateral hearing aids for at least the past 2 years.ResultsThere were significant delays in the auditory P1-N1-P2 complex in older adults with hearing loss compared with their normal hearing peers when using equal sound pressure levels for all participants. However, when the degree and configuration of hearing loss were accounted for through the presentation of equal sensation level stimuli, no latency delays were observed. These results suggest that stimulus audibility modulates P1-N1-P2 morphology and should be controlled for when defining deprivation and stimulus-related neuroplasticity in people with hearing loss. Moreover, a history of auditory stimulation, in the form of hearing aid use, does not appreciably alter the neural registration of unaided auditory evoked brain activity when quantified by the P1-N1-P2.ConclusionsWhen comparing auditory cortical responses in older adults with and without hearing loss, stimulus audibility, and not hearing loss-related neurophysiological changes, results in delayed response latency for those with age-related hearing loss. Future studies should carefully consider stimulus presentation levels when drawing conclusions about deprivation- and stimulation-related neuroplasticity. Additionally, auditory stimulation, in the form of a history of hearing aid use, does not significantly affect the neural registration of sound when quantified using the P1-N1-P2-evoked response.

Project description:In light of the high prevalence of hearing loss and cognitive impairment in the aging population, it is important to know how cognitive tests should be administered for older adults with hearing loss. The purpose of the present study is to examine this question with a cognitive screening test and a working memory test. Specifically, we asked the following questions in 2 experiments. First, does a controlled amplification method affect cognitive test scores? Second, does test modality (visual vs. auditory) impact cognitive test scores? Three test administration conditions were created for both Montreal Cognitive Assessment (MoCA) and working memory test (a word recognition and recall test): auditory amplified, auditory unamplified, and visual. The auditory administration was implemented through a computer program to control for presentation level while the visual condition was implemented through timed computer slides. Data were collected from older individuals with mild-to-moderate sensorineural hearing loss. We did not find any effect of amplification or test modality on the total score of the cognitive screening test (i.e., MoCA). Amplification improved working memory performance as measured by word recall performance, but test modality (auditory vs. visual) did not. These results are consistent with literature in demonstrating a downstream effect of audibility on working memory performance. From a clinical perspective, these findings are informative for developing clinical administration protocols of these tests for older individuals with hearing loss.

Project description:Neuropsychiatric symptoms (NPS) in persons with dementia (PWD) are common and can lead to poor outcomes, such as institutionalization and mortality, and may be exacerbated by sensory loss. Hearing loss is also highly prevalent among older adults, including PWD.ObjectiveThis study investigated the association between hearing loss and NPS among community- dwelling patients from a tertiary memory care center.Design, setting, and participantsParticipants of this cross-sectional study were patients followed at the Johns Hopkins Memory and Alzheimer's Treatment Center who underwent audiometric testing during routine clinical practice between October 2014 and January 2017.Outcome measurementsIncluded measures were scores on the Neuropsychiatric Inventory-Questionnaire and the Cornell Scale for Depression in Dementia.ResultsParticipants (n = 101) were on average 76 years old, mostly female and white, and had a mean Mini-Mental State Examination score of 23. We observed a positive association between audiometric hearing loss and the number of NPS (b = 0.7 per 10 dB; 95% confidence interval [CI]: 0.2, 1.1; t = 2.86; p = 0.01; df = 85), NPS severity (b = 1.3 per 10 dB; 95% CI: 0.4, 2.5; t = 2.13; p = 0.04; df = 80), and depressive symptom severity (b = 1.5 per 10 dB; 95% CI: 0.4, 2.5; t = 2.83; p = 0.01; df = 89) after adjustment for demographic and clinical characteristics. Additionally, the use of hearing aids was inversely associated with the number of NPS (b = -2.09; 95% CI -3.44, -0.75; t = -3.10; p = 0.003; df = 85), NPS severity (b = -3.82; 95% CI -7.19, -0.45; t = -2.26; p = 0.03; df = 80), and depressive symptom severity (b = -2.94; 95% CI: -5.93, 0.06; t = 1.70; p = 0.05; df = 89).ConclusionAmong patients at a memory clinic, increasing severity of hearing loss was associated with a greater number of NPS, more severe NPS, and more severe depressive symptoms, while hearing aid use was associated with fewer NPS, lower severity, and less severe depressive symptoms. Identifying and addressing hearing loss may be a promising, low-risk, non-pharmacological intervention in preventing and treating NPS.

Project description:ObjectivesTo investigate the landscape of cognitive impairment (CI) screening for adults with age-related hearing loss (ARHL) among otolaryngologists and audiologists. To identify provider factors and patient characteristics that impact rates of CI screening and referral.MethodsA 15 question online survey was sent to members of the Georgia Society of Otolaryngology (GSO), Georgia Academy of Audiology (GAA), American Otological Society and American Neurotology Society (AOS/ANS), and posted on the web forum for two hearing disorders special interest groups within the American-Speech-Language-Hearing Association (ASHA). Responses were collected anonymously. Chi-square tests were used to compare responses.ResultsOf the 66 included respondents, 61% (n = 40) were otolaryngologists and 35% (n = 23) were audiologists. Respondents were significantly more likely to refer patients for CI assessment than to screen (64% vs 21%, respectively, P < .001). The complaint of a neurological symptom, such as memory loss, would prompt screening or referral for only 27.3% (n = 18) and 51.52% (n = 34) of respondents, respectively. Forty-two percent (n = 28) of respondents suggested CI screening with the MMSE vs 20% (n = 13) with the Montreal Cognitive Assessment.ConclusionsDespite recommendations for cognitive assessment in high-risk populations, such as older adults with ARHL, the practice of CI screening and referral is not yet commonplace among otolaryngologists and audiologists. These providers have a unique opportunity to assess adults with ARHL for CI and ensure appropriate referral.Level of evidence5.

Project description:Tooth loss is associated with both cognitive impairment and fall risk. However, the relationships between these variables are complex and bidirectional. Observed associations have been reported in separate studies but data on rural-dwelling older adults remain sparse. This cross-sectional study investigated socioeconomic and dental factors affecting cognitive functions, and the association between tooth loss, cognitive functioning, and fall risk. Two hundred and thirty-one rural-dwelling older adults (60-74 years old) were recruited from a single Dental Service Unit. Cognitive function and fall risk were assessed with the Mini-Mental State Examination and the Morse Fall Scale, respectively. Oral examinations were performed by a dentist using the Community Periodontal Index of Treatment Needs form. 38.1%, had >16 tooth loss. Socioeconomic data and health status were obtained from a questionnaire and interviews. Age, Activities of Daily Living (ADL) score, and the number of teeth lost was significantly associated with impaired cognitive function. Chi-square analysis showed that cognitive function was also associated with fall risk. Past research suggests that much cognitive impairment and fall risk is induced by tooth loss. Service planners need to be aware of the complex bidirectional relationships between these variables and give higher priority to dental services that can improve the general health status and social functioning of older rural adults.

Project description:ObjectiveTo examine the association between hearing loss and cognitive function cross-sectionally and prospectively among older adults with atrial fibrillation (AF).MethodsPatients with AF ≥ 65-year-old (n = 1244) in the SAGE (Systematic Assessment of Geriatric Elements)-AF study were recruited from five internal medicine or cardiology clinics in Massachusetts and Georgia. Hearing was assessed by a structured questionnaire at baseline. Cognitive function was assessed by Montreal Cognitive Assessment (MoCA) at baseline and one year. Cognitive impairment was defined as score ≤ 23 on the MoCA. The associations between hearing loss and cognitive function were examined by multivariable adjusted logistic regression.ResultsParticipants with hearing loss (n = 451, 36%) were older, more likely to be male, and have depressive symptoms than patients without hearing loss. At baseline, 528 (42%) participants were cognitively impaired. Individuals with hearing loss were significantly more likely to have cognitive impairment at baseline [adjusted odds ratio (OR) = 1.37, 95% confidence interval (CI): 1.05-1.81]. Among the 662 participants who did not have cognitive impairment at baseline and attended the one-year follow-up visit, 106 (16%) developed incident cognitive impairment. Individuals with, versus those without, hearing loss were significantly more likely to develop incident cognitive impairment at one year (adjusted OR = 1.68, 95% CI: 1.07-2.64).ConclusionsHearing loss is a prevalent but under-recognized factor associated with cognitive impairment in patients with AF. Assessment for hearing loss may be indicated among these patients to identify individuals at high-risk for adverse outcomes.

Project description:ObjectiveTo index levels of hearing loss with respect to area-level indices of deprivation in a Welsh population.DesignA cross-sectional observational study of all adults (aged >18) that attended Abertawe Bro Morgannwg University (ABMU) Health Board audiology services between 2016 and 2018. Service access, first hearing aid fitting appointment rates and hearing loss at time of first hearing aid provision were used to index population hearing loss versus area-level indices of deprivation based on patient postcode.SettingPrimary and secondary care.Participants59 493 patient entries met the inclusion criteria. Patient entries were grouped by age (18-30, 31-40, 41-50, 51-60, 61-70, 71-80, >80 years) and deprivation decile.ResultsThe interaction between age group and deprivation decile predicted access rate to ABMU audiology services (b=-0.24, t(6858) = -2.86, p<0.01) with audiology services accessed more frequently by the most deprived versus the least deprived decile in every age group (p<0.05), except the >80 years. First hearing aid fitting rates were highest among the most deprived in the four youngest age groups (p<0.05). Severity of hearing loss at the time of first hearing aid fitting was worse among the most deprived in the five oldest age groups (p<0.01).ConclusionsHearing health inequalities are prevalent among adults accessing ABMU audiology services. Our findings suggest that deprivation increases the likelihood of developing hearing loss, brings earlier onset of hearing loss and is linked to delays in getting help for hearing problems. However, it is not possible to know the true scale of these disparities without knowing the hearing health of the Welsh adult population including those who do not seek help for hearing problems.
