Increased risk of depression in patients with acquired sensory hearing loss: A 12-year follow-up study

Association of hearing loss and risk of depression: a systematic review and meta-analysis

Background

Previous studies have suggested a possible link between hearing loss and the risk of depression. However, the strength of this association remains uncertain across varying follow-up periods, age groups, cohort studies, and longitudinal study designs.

Methods

We conducted an extensive literature search across PubMed, Embase, and the Cochrane Library databases to retrieve pertinent studies. The quality of observational studies was assessed using the Newcastle-Ottawa Scale. Synthesis and meta-analysis of odds ratios (ORs) along with corresponding 95% confidence intervals (CIs) were performed using Stata 14.0. Funnel plot analysis and Egger's regression test were utilized to assess potential publication bias.

Results

This meta-analysis comprised 24 cohort studies conducted between 2007 and 2024, with sample sizes ranging from 548 to 254,466 participants. Among these participants, 24,304 had experienced depression events. The pooling analysis shows that hearing loss is associated with an increased risk of depression (OR = 1.35; 95%CI: 1.27-1.44). In the subgroup analysis, the retrospective cohort exhibited a slightly higher risk of depression compared to the prospective cohort (OR = 1.43; 95% CI: 1.30-1.58). There are differences in the risk of depression among young, middle-aged, and older individuals, with older adults facing a higher risk (OR = 1.33, 95% CI: 1.21-1.45). Additionally, the risk of depression was slightly higher in the sudden sensorineural hearing loss (SSNHL) group compared to the non-SSNHL group (OR = 1.62; 95% CI: 1.27-2.07). Furthermore, in cohorts with a follow-up time ≥ 5 years, the risk of depression was higher compared to those with <5 years of follow-up (OR = 1.39; 95% CI: 1.26-1.54).

Conclusion

Our meta-analysis shows that hearing loss increases the risk of depression. These findings provide evidence that hearing loss should be recognized as an independent risk factor for depression.

Contribution of Tinnitus and Hearing Loss to Depression: NHANES Population Study

OBJECTIVES

Hearing loss affects the emotional well-being of adults and is sometimes associated with clinical depression. Chronic tinnitus is highly comorbid with hearing loss and separately linked with depression. In this article, the authors investigated the combined effects of hearing loss and tinnitus on depression in the presence of other moderating influences such as demographic, lifestyle, and health factors.

DESIGN

The authors used the National Health and Nutrition Examination Survey data (2011-2012 and 2015-2016) to determine the effects of hearing loss and tinnitus on depression in a population of US adults (20 to 69 years). The dataset included the Patient Health Questionnaire-9 for depression screening, hearing testing using pure-tone audiometry, and information related to multiple demographic, lifestyle, and health factors (n = 5845).

RESULTS

The statistical analysis showed moderate to high associations between depression and hearing loss, tinnitus, and demographic, lifestyle, and health factors, separately. Results of logistic regression analysis revealed that depression was significantly influenced by hearing loss (adjusted odds ratios [OR] = 3.0), the functional impact of tinnitus (adjusted OR = 2.4), and their interaction, both in the absence or presence of the moderating influences. The effect of bothersome tinnitus on depression was amplified in the presence of hearing loss (adjusted OR = 2.4 in the absence of hearing loss to adjusted OR = 14.9 in the presence of hearing loss). Conversely, the effect of hearing loss on depression decreased when bothersome tinnitus was present (adjusted OR = 3.0 when no tinnitus problem was present to adjusted OR = 0.7 in the presence of bothersome tinnitus).

CONCLUSIONS

Together, hearing loss and bothersome tinnitus had a significant effect on self-reported depression symptoms, but their relative effect when comorbid differed. Tinnitus remained more salient than hearing loss and the latter's contribution to depression was reduced in the presence of tinnitus, but the presence of hearing loss significantly increased the effects of tinnitus on depression, even when the effects of the relevant demographic, lifestyle, or health factors were controlled. Treatment strategies that target depression should screen for hearing loss and bothersome tinnitus and provide management options for the conditions.

Bidirectional associations between sensorineural hearing loss and depression and anxiety: a meta-analysis

Background

Recently, the prevalence of sensorineural hearing loss (SNL) has been increasing, and several studies have suggested that depression, anxiety, and SNL may be associated with each other, however, individual findings still have discrepancies. To the best of our knowledge, no scholars have systematically elucidated the bidirectional associations between SNL, depression, and anxiety disorders from the perspective of meta-analysis. In this study, we aimed to systematically evaluate the bidirectional associations between SHL and depressive and anxiety symptoms, and to provide evidence-based medical evidence for reducing SNL, depression, and anxiety disorders.

Methods

We performed systematic review based on priori protocol that was registered with PROSPERO (No. CRD42022365963). Systematic search of PubMed, Embase, and Web of Science databases identified articles published as of June 1, 2023, on the relationship between SNL and depression and anxiety. Meta-analysis was performed to calculate the odds ratios (OR) and 95% confidence intervals (CIs) for the outcome metrics, and the results were combined to assess bivariate associations between the disorders with fixed or random effects. Sensitivity and subgroup analyzes were conducted to analyze sources of heterogeneity, and Egger's and Begg's tests combined with funnel plots were applied to assess publication bias.

Results

Summary analysis of the results of 20 studies covering 675,291 individuals showed that the bidirectional association between SNL and depression and anxiety disorders. The incidence (OR = 0.17, 95% CI: 0.09-0.28) and risk (OR = 1.43, 95% CI: 1.32-1.55) of depression and morbidity were higher in SNL patients than the general population. Elevated prevalence (OR = 0.46, 95% CI: 0.28-0.65) and risk (OR = 1.30, 95% CI: 1.11-1.48) of SNL were also observed in depressed patients. The prevalence of anxiety disorders among SNL patients was about 40% (OR = 0.40, 95% CI: 0.24%-0.57), which was associated with higher risk (OR = 1.83, 95% CI: 1.42-2.24) of development than the general population. Incidence of SNL in patients with anxiety disorders was approximately 31% (OR = 0.31, 95% CI: 0.29-0.33). Additionally, subgroup analyzes showed that the bidirectional associations between SNL, depression, and anxiety disorders was influenced by age, region, and mode of diagnosis of the disorders (SNL, depression, anxiety).

Conclusion

There are bidirectional associations between SNL and depression and anxiety disorders, which was influenced by age and region and the method the disorders (SNL, depression, anxiety) were diagnosed.

Aging Makes the Heart Grow Fonder: Age Influences Hearing Ability and Interactions between Psychological Phenomena in Patients with Chronic Tinnitus

(1) Background: Risk factors for chronic tinnitus comprise interactions of individuals' hearing difficulties and psychological distress-including anxiety, depression, and perceived stress levels. Both groups of factors likely become more pronounced with age, although mixed literature has also suggested increases in psychological resilience over time. To this end, only a few studies have delineated direct and indirect effects of age on audiological and psychological variables that might influence tinnitus-related distress in patients with chronic tinnitus. (2) Methods: N = 678 patients with chronic tinnitus completed audiological assessments alongside self-report measures of psychological and tinnitus-related distress. Path analyses investigated the effect of age on patients' tinnitus-related distress via both audiological and psychological variables. (3) Results: Age was significantly associated with both hearing ability and psychological distress indices, with perceived stress and anxiety decreasing with aging. Different mediation models revealed that the association between age and tinnitus-related distress was mediated completely by hearing ability and partly by perceived stress and anxiety. (4) Conclusions: Whilst interactions of individuals' hearing ability and psychological distress levels maintain tinnitus-related distress across the age span, the weighting of these factors may shift with age. Treatment approaches should consider hearing ability across the lifespan. Psychological factors should be individually conceptualized, considering both distress-related and potential resilience factors in old age.

Cochlear Implantation in Hearing-Impaired Elderly: Clinical Challenges and Opportunities to Optimize Outcome

Cochlear implant (CI) overall provides a very good outcome, but speech comprehension outcome in the elderly is more variable. Several clinical factors play an important role. The management of residual hearing, the presence of comorbidities, and especially the progression of cognitive decline seem to be the clinical parameters that strongly determine the outcome of cochlear implantation and need to be discussed prospectively in the consultation process with the elderly hearing impaired. In the context of this review article, strategies for dealing with these will be discussed. Timely cochlear implantation should already be considered by hearing aid acousticians or practicing otolaryngologists and communicated or initiated with the patient. This requires intensive cooperation between hearing aid acousticians and experts in the clinic. In addition, residual hearing and comorbidities in the elderly need to be considered to make realistic predictions about speech comprehension with CI. Long-term aftercare and its different implementations should be discussed preoperatively, so that the elderly person with hearing impairments feels well taken care of together with his or her relatives. Elderly patients with hearing impairments benefit most from a CI in terms of speech comprehension if there is a large cochlear coverage (electrical or acoustic electrical) and the therapy is not hampered by comorbidities, especially cognitive decline.

Hearing loss, depression and social participation of older adults: Evidence from the China health and retirement longitudinal study

AIM

Hearing loss and depression in older adults are associated with a lower social participation rate. However, few studies have thoroughly analyzed the relationship between them.

METHODS

The data were obtained from the China Health and Retirement Longitudinal Study carried out in 2011, 2013 and 2015, and data from 24 306 participants ranging in age from 50 to 80 years were used in this study. Hearing loss, depression and social participation were assessed by self-reported hearing status, the 10-item Center for the Epidemiological Studies of Depression Short Form, and self-reported social participation activity types and frequency. The fixed effects logistic regression and random effects logistic regression were used to examine the relationship between hearing loss and social participation. The Sobel method was used to explore the relationship between hearing loss, depression and social participation.

RESULTS

Compared with older adults without hearing loss, persons with hearing loss engaged in significantly fewer types of activities (β = -0.070, 95% CI -0.109, -0.031, P < 0.001) and at a lower frequency (β = -0.176, 95% CI -0.260, -0.093, P < 0.001). Depression significantly existed in the relationship between hearing loss and social participation as a mediating variable, and the percentage of indirect effects in this relationship were 16.5% and 20.8%.

CONCLUSIONS

The findings of this study suggest that when facing an aging society, improving the hearing status of older adults should be considered by policymakers. More efforts should be made to help older adults cope with depression. Geriatr Gerontol Int 2022; ••: ••-••.

Association between Ultraviolet B Exposure Levels and Depression in Taiwanese Adults: A Nested Case-Control Study

Depression is a common mental disorder that affects more than 264 million people worldwide. Anxiety, diabetes, Alzheimer's disease, myocardial infarction, and cancer, among other disorders, are known to increase the risk of depression. Exposure to ultraviolet B (UVB) can cause human serotonin levels to increase. The vitamin D pathway is one mechanism through which ultraviolet light absorbed through the skin can affect mood; however, UVB exposure is known to increase the risk of cancer. In this study, we explored the effects of prolonged exposure to UVB on depression. Data were retrieved from the Taiwan National Health Insurance Research Database for 2008 to 2013. Each patient with depression was matched 1:4 with a comparison patient by sex and age (±5 years); thus, the study included 23,579 patients with depression and 94,316 healthy controls for comparison. The patients had been exposed to UVB for at least 1 year to observe the cumulative effect of UVB exposure. Based on the World Health Organization UV index, we divided the observation period data into five UV levels: low, moderate, high, very high, and extreme. A multivariate Poisson regression model was used to assess the risk of depression according to UVB exposure level, adjusting for sex, age, income, urbanization level, month, and comorbidities. The results revealed that the incidence rate ratio (IRR) for patients with depression was 0.889 for moderate levels (95% CI 0.835-0.947), 1.134 for high levels (95% CI: 1.022-1.260), 1.711 for very high levels (95% CI: 1.505-1.945), and 2.785 for extreme levels (95% CI: 2.439-3.180) when compared to low levels. Moderate levels of UVB lowered the risk of depression, while high levels of UVB gradually increased the risk. We propose that UVB at normal concentrations can effectively improve depression. However, exposure to high concentrations of UVB damage DNA results in physical diseases such as skin cancer, which increase the risk of depression.

Relationship between hearing loss and depression symptoms among older adults in China: The mediating role of social isolation and loneliness

OBJECTIVES

To evaluate whether social isolation and loneliness mediates the relationship between hearing loss and depression symptoms in older adults in China.

METHODS

A cross-sectional analysis was conducted of 3769 participants (aged≥60 years) in Shandong province of China. Hearing loss was assessed using Pure-Tone Audiometry test, depression symptoms using 15-item Geriatric Depression Scale, loneliness through UCLA Loneliness Scale and social isolation using Lubben Social Network Scale. Regression and bootstrap analyses were performed to test both direct associations of hearing loss and depression symptoms, and whether the mediating role of social isolation and loneliness.

RESULTS

Overall, 44% of older adults had hearing loss, which was generally mild (30%) rather than moderate (10%), severe (3%) or profound (0.6%). Increasing levels of hearing loss was associated with increasing levels of social isolation and depressions. Hearing loss was also associated with loneliness, but here a threshold effect was apparent and no trend for increasing loneliness with increasing hearing loss. Models that included social isolation and loneliness showed an amelioration in the association of hearing loss and depression, although it remained significant at all levels of hearing loss. Overall, 8% of the total effect of hearing loss on depression symptoms was explained by the mediated effect through social isolation and 42% by loneliness.

CONCLUSIONS

Psychosocial factors such as social isolation and loneliness might explain the association between hearing loss and depression. Interventions that address older adults' social isolation and loneliness may ameliorate depression in older adults with hearing loss.

Hearing loss, depression, and medical service utilization among older adults: evidence from China

OBJECTIVES

To acquire a better understanding of the mechanisms underlying the association between hearing loss and medical service utilization, this study examined the relationship between hearing loss, depression, and medical service utilization.

STUDY DESIGN

Using the methods of probability proportional to size, a survey conducted in 28 provinces, 150 countries/districts, 450 villages/urban communities, 11,628 households, and 19,816 individuals of China in 2018.

METHODS

The data for this article were derived from the 2018 China Health and Retirement Longitudinal Study, which enrolled 14,455 people aged 50-80 years. Hearing loss was determined using self-reported hearing status. Self-reported outpatient visits in the last month and hospitalization within the last year were used to determine medical service utilization. Depression was obtained from the CES-D-10 scale. Logistic regression and stepwise regression methods were used.

RESULTS

Older adults with hearing loss problems used significantly more outpatient care services (odds ratio [OR] = 1.292, 95% confidence interval [CI] 1.152, 1.449; P < 0.001) and inpatient care services (OR = 1.238, 95% CI 1.021, 1.501; P < 0.05) than those without hearing loss problems. Following that, individuals with hearing loss problems were more likely to experience depressive symptoms (OR = 1.467, 95% CI 1.345, 1.599; P < 0.001) than those without. Moreover, respondents with depressive symptoms used outpatient care services at a significantly higher rate (OR = 1.292, 95% CI 1.152, 1.449; P < 0.001) and inpatient care service at a significantly higher rate (OR = 1.238, 95% CI 1.021, 1.501; P < 0.05) compared with those without depressive symptom.

CONCLUSION

This article discovered that depression acted as a mediation variable in the relationship between hearing loss and medical service utilization. This research provided possible interventions for reducing the burden of the healthcare system and society that older adults with hearing loss imposed.

Longitudinal Associations of Self-Reported Visual, Hearing, and Dual Sensory Difficulties With Symptoms of Depression Among Older Adults in the United States

Evidence conflicts on the association between sensory difficulty and depression. Few studies have examined this association using longitudinal or population-based data. We used data from Rounds 1-9 of the nationally representative National Health and Aging Trends Study to evaluate the longitudinal association between self-reported visual, hearing, and dual sensory difficulties and clinically significant depressive symptoms. Multivariable Cox regression models were used to evaluate the hazard of incident depressive symptoms. Group-based trajectory modeling identified depressive symptom trajectories (DSTs). Multinomial logistic regression was used to examine the association between sensory status and DSTs. A total of 7,593 participants were included: 56.5% were female, 53.0% were 65-74 years old, 19.0% (95% CI 17.9-20.2%) had hearing, 5.6% (4.9-6.4%) had visual, and 3.3% (2.9-3.8%) had dual sensory difficulties at baseline. Hazard ratios for depressive symptoms in those with visual, hearing, and dual sensory difficulties were 1.25 (95% CI 1.00-1.56, p = 0.047), 0.98 (95% CI 0.82-1.18, p = 0.82), and 1.67 (95% CI 1.29-2.16, p < 0.001), respectively, relative to those without sensory difficulty. A model with four trajectory groups best fit the data. Group 1 (35.8% of the sample, 95% CI: 34.1-37.4) had persistently low risk of depressive symptoms; Group 2 (44.8%, 43.4-46.3) had low but increasing risk; Group 3 (7.1%, 6.2-8.3) had moderate risk; and Group 4 (12.4%, 11.5-13.3) had moderate to high risk that increased. Compared to those without sensory difficulties, individuals with each difficulty were significantly more likely to belong to a group other than Group 1. This study reveals associations between sensory difficulties and mental health that can inform public health interventions.

The dynamic relationship between hearing loss, quality of life, socioeconomic position and depression and the impact of hearing aids: answers from the English Longitudinal Study of Ageing (ELSA)

PURPOSE

The adverse impact of hearing loss (HL) extends beyond auditory impairment and may affect the individuals' psychosocial wellbeing. We aimed to examine whether there exists a causal psychosocial pathway between HL and depression in later life, via socioeconomic factors and quality of life, and whether hearing aids usage alleviates depressive symptoms over time.

METHODS

We examined the longitudinal relationship between HL and depressive symptoms (CES-D) applying dynamic cross-lagged mediation path models. We used the full dataset of participants aged 50-89 years (74,908 person-years), from all eight Waves of the English Longitudinal Study of Ageing (ELSA). Their quality of life (CASP-19) and their wealth were examined as the mediator and moderator of this relationship, respectively. Subgroup analyses investigated differences among those with hearing aids within different models of subjectively and objectively identified HL. All models were adjusted for age, sex, retirement status and social engagement.

RESULTS

Socioeconomic position (SEP) influenced the strength of the relationship between HL and depression, which was stronger in the lowest versus the highest wealth quintiles. The use of hearing aids was beneficial for alleviating depressive symptoms. Those in the lowest wealth quintiles experienced a lower risk for depression after the use of hearing aids compared to those in the highest wealth quintiles.

CONCLUSION

HL poses a substantial risk for depressive symptoms in older adults, especially those who experience socioeconomic inequalities. The early detection of HL and provision of hearing aids may not only promote better-hearing health but could also enhance the psychosocial wellbeing of older adults, particularly those in a lower SEP.

Effectiveness of a Self-Fitting Tool for User-Driven Fitting of Hearing Aids

Hearing aids can be effective devices to compensate for age- or non-age-related hearing losses. Their overall adoption in the affected population is still low, especially in underdeveloped countries in the subpopulation experiencing milder hearing loss. One of the major reasons for low adoption is the need for repeated complex fitting by professional audiologists, which is often not completed for various reasons. As a result, self-fitting procedures have been appearing as an alternative. Key open questions with these digital tools are linked to their effectiveness, utilized algorithms, and achievable end-results. A digital self-fitting prototype tool with a novel quick four-step fitting workflow was evaluated in a study on 19 individuals with moderate hearing loss. The tool was evaluated in a double-blinded, randomized study, having two study aims: comparing traditional audiological fitting with the new self-fitting tool, which can also be used as a remote tool. The main reported results show moderately high usability and user satisfaction obtained during self-fitting, and quasi-equivalence of the performance of the classical audiological fitting approach. The digital self-fitting tool enables multiple sessions and easy re-fitting, with the potential to outperform the classical fitting approach.

Implementation of a Hearing Loss Screening Intervention in Primary Care

PURPOSE

Hearing loss (HL) is underdiagnosed and often unaddressed. A recent study of screening for HL using an electronic prompt showed efficacy in increasing appropriate referrals for subsequent testing. We build on the results of this study using a qualitative lens to explore implementation processes through the perspectives of family medicine clinicians.

METHODS

We collected clinic observations and semistructured interviews of family medicine clinicians and residents who interacted with the HL prompt. All data were analyzed using thematic, framework, and mixed methods integration strategies.

RESULTS

We interviewed 27 clinicians and conducted 10 observations. Thematic analysis resulted in 6 themes: (1) the prompt was overwhelmingly viewed as easy, simple to use, accurate; (2) clinicians considered prompt as an effective way to increase awareness and conversations with patients about HL; (3) clinician and staff buy-in played a vital role in implementation; (4) clinicians prioritized prompt during annual visits; (5) medical assistant involvement in prompt workflow varied by health system, clinic, and clinician; (6) prompt resulted in more conversations about HL, but uncertain impact on patient outcomes. Themes are presented alongside constructs of normalization process theory and intervention outcomes.

CONCLUSION

Integration of a HL screening prompt into clinical practice varied by clinician buy-in and beliefs about the impact on patient outcomes, involvement of medical assistants, and prioritization during clinical visits. Further research is needed to understand how to leverage clinician and staff buy-in and whether implementation of a new clinical prompt has sustained impact on HL screening and patient outcomes.

Predicting Depression From Hearing Loss Using Machine Learning

OBJECTIVES

Hearing loss is the most common sensory loss in humans and carries an enhanced risk of depression. No prior studies have attempted a contemporary machine learning approach to predict depression using subjective and objective hearing loss predictors. The objective was to deploy supervised machine learning to predict scores on a validated depression scale using subjective and objective audiometric variables and other health determinant predictors.

DESIGN

A large predictor set of health determinants from the National Health and Nutrition Examination Survey 2015-2016 database was used to predict adults' scores on a validated instrument to screen for the presence and severity of depression (Patient Health Questionnaire-9 [PHQ-9]). After model training, the relative influence of individual predictors on depression scores was stratified and analyzed. Model prediction performance was determined by prediction error metrics.

RESULTS

The test set mean absolute error was 3.03 (95% confidence interval: 2.91 to 3.14) and 2.55 (95% confidence interval: 2.48 to 2.62) on datasets with audiology-only predictors and all predictors, respectively, on the PHQ-9's 27-point scale. Participants' self-reported frustration when talking to members of family or friends due to hearing loss was the fifth-most influential of all predictors. Of the top 10 most influential audiometric predictors, five were related to social contexts, two for significant noise exposure, two objective audiometric parameters, and one presence of bothersome tinnitus.

CONCLUSIONS

Machine learning algorithms can accurately predict PHQ-9 depression scale scores from National Health and Nutrition Examination Survey data. The most influential audiometric predictors of higher scores on a validated depression scale were social dynamics of hearing loss and not objective audiometric testing. Such models could be useful in predicting depression scale scores at the point-of-care in conjunction with a standard audiologic assessment.

A dimensional approach to understanding the relationship between self-reported hearing loss and depression over 12 years: the Three-City study

Objectives: To examine the relationship between hearing loss and depression in older adults longitudinally. This paper uses a dimensional approach to conceptualising depression, with the aim of further enhancing understanding of this relationship.Method: 8344 community-dwelling adults aged 65 years and above enrolled in the Three-City prospective cohort study were included. Relationships between baseline self-reported hearing loss (HL) with the trajectory of different dimensions of depression symptoms over 12 years were examined using linear mixed models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD): depressed affect, positive affect, somatic symptoms and interpersonal problems.Results: HL was associated with somatic symptoms of depression both at baseline (b = .07, p = .04) and over 12 years (b = .01, p = .04). HL was associated with poorer depressed affect and interpersonal problems at baseline (b = .05, p = .001, b = .35, p < .001; respectively), but not over follow-up. HL was associated with poorer positive affect symptoms over time (b = -.01, p = .01).Conclusion: HL had varied relationships with different dimensions of depression symptoms, and there were different patterns of adjustment for the dimensions. HL was primarily associated with somatic symptoms, suggesting that shared disease processes might partly underlie the relationship between HL and depression. Targeted assessment and treatment of somatic and positive affect symptoms in older adults with HL might facilitate better wellbeing in this population.

Association between Hearing Loss and Cognitive Disorder: A Nationwide Population-Based Study

PURPOSE

To investigate the relationship between hearing loss and cognitive disorder with memory dysfunction in South Korea using data from the Korean Health Insurance claims database for 2009-2015.

MATERIALS AND METHODS

We analyzed cross-sectional data of 66-year-old individuals who completed the Korea National Health and Nutrition Examination Surveys. Auditory function was evaluated using pure-tone audiometric testing. Cognitive disorder with memory dysfunction was assessed using standardized scores of the Prescreening Korean Dementia Screening Questionnaire.

RESULTS

Among 1815835 participants at the age of 66 years, the prevalence of unilateral hearing loss was 5.84%, and that of bilateral hearing loss was 3.40%. The normal cognitive group comprised 86.35% of the participants, and the high-risk group for cognitive disorder with memory dysfunction totaled 13.65% of the participants. The bilateral hearing loss group had the highest percentage of subjects who responded "sometimes or frequently" to all five questions about cognitive disorder with memory dysfunction, compared to the normal hearing group or the unilateral hearing loss group. After adjusting for sex, smoking status, alcohol intake, exercise, income, diabetes, hypertension, dyslipidemia, and depression, the odds ratios for cognitive disorder with memory dysfunction was 1.183 [95% confidence interval (CI): 1.163-1.203] for bilateral hearing loss and 1.141 (95% CI: 1.126-1.156) for unilateral hearing loss, compared to the normal cognitive group.

CONCLUSION

Hearing loss has a significant effect on cognitive function in the Korean population. In our study, individuals with bilateral hearing loss showed poorer cognitive function than those with unilateral hearing loss.

The longitudinal effect of sensory loss on depression among Chinese older adults

BACKGROUND

Previous studies have suggested that sensory loss is linked to depression. However, most of these studies have been conducted in developed countries and the results are mixed.

OBJECTIVES

The current study aims to examine the longitudinal relationship between hearing loss, vision loss, dual sensory loss, and depression among Chinese older adults over four years.

METHODS

The data were obtained from the China Health and Retirement Longitudinal Survey (CHARLS). In total, 6353 Chinese older adults aged 60 years and over were included at baseline in this study. Self-reported hearing and vision status was used, and dual sensory loss was a combined variable of hearing loss and vision loss. Depressive symptoms were assessed by The Center for Epidemiologic Studies Depression Scale (CESD-10). The baseline relationship between sensory loss and depression was explored by logistic regression analyses. A logistic mixed model was used to assess whether baseline sensory loss was associated with incident depression for older adults with no depressive symptoms at baseline over four years.

RESULTS

At baseline, vision loss (OR=1.46, 95%CI: 1.19-1.79) and dual sensory loss (OR=2.14, 95%CI: 1.77-2.58) were associated with depression, while hearing loss was not. After four years, vision loss (OR=1.60, 95%CI: 1.16-2.22) and dual sensory loss (OR=1.78, 95%CI: 1.32-2.41) were associated with incident depression.

LIMITATIONS

Not all potential confounding factors are measured and adjusted in the analysis. Apart from that, all measurements of interest are self-reported scales.

CONCLUSION

Vision loss and dual sensory loss are significantly associated with both onset and increased depressive symptoms over time, while hearing loss is not associated with depression. Interactions between all types of sensory loss and social activities are not significant. Our results suggest that target mental health intervention programs should be delivered to vision loss or dual sensory loss populations.

Experiences of Hearing Loss and Audiological Rehabilitation for Older Adults With Comorbid Psychological Symptoms: A Qualitative Study

Purpose There is a well-established relationship between hearing loss and psychological symptoms. To ensure audiological rehabilitation is provided appropriately for older adults with comorbid psychological symptoms, a greater understanding of their preferences and experiences is needed. This study sought to understand experiences of hearing loss and audiological rehabilitation from the perspective of older adults with comorbid psychological symptoms (e.g., depression, anxiety, psychosis). Design A qualitative study using in-depth semistructured interviews was conducted with older adults who had attended audiological rehabilitation within the last year and scored above established cutoffs on measures of depression, anxiety, and psychosis. A thematic analysis generated themes that related to participants' experiences of hearing loss and audiological rehabilitation. Results Participants included 14 older adults (eight men and six women) with an average age of 70.5 years (SD = 4.45, range: 64-80) who received hearing aids or a cochlear implant. Three major themes emerged from the analysis of participant interviews. "The cumulative impact of hearing loss and psychological symptoms" theme describes the two-way, additive relationship between hearing ability and psychological symptoms. "The experience of loss throughout hearing loss and audiological rehabilitation" captures subjective losses, the impact they have, and how participants cope with them. In contrast, "The experience of gain throughout hearing loss and audiological rehabilitation" describes the participants' reported gains, their related impacts, and coping strategies. Conclusions The experiences of participants revealed that the presence of comorbid psychological symptoms can influence the experience of hearing loss and audiological rehabilitation. These findings have implications for how audiological rehabilitation is provided to ensure optimal outcomes for adults with hearing loss and comorbid psychological symptoms.

Benefits of Cochlear Implantation in Middle-Aged and Older Adults

Introduction

Nowadays cochlear implantation (CI) is the treatment of choice in adults in case conventional hearing devices fail. Besides speech perception, an improvement in quality of life and in cognitive performance has been reported. Thereby, the study focused on the impact of age.

Participants and Methods

Thirty middle-aged (MA) between 50 and 64 years and 41 older subjects (OA) aged 65 and older with bilateral severe hearing loss performed a comprehensive computer-based neurocognitive test battery (ALAcog) pre- and 12 months post-implantation. Besides, monosyllabic speech perception in quiet (Freiburg monosyllabic speech test), health-related quality of life (HR-QoL, Nijmegen Cochlear Implant Questionnaire) and depressive symptoms (GDS-15) have been assessed.

Results

Both age groups significantly improved in all three categories after 12 months. No differences were evaluated between MA and OA regarding speech perception and HR-QoL pre- and post-operatively. In contrast, cognitive performance differed between the age groups: pre-operatively OA performed worse in most neurocognitive subdomains like working memory (p=0.04), inhibition (p=0.004), processing speed (p=0.003) and mental flexibility (p=0.01), post-operatively MA outperformed OA only in inhibition (p=0.01). Age only slightly influenced cognitive performance in MA, whereas in OA age per se tremendously impacted on working memory (p=0.04), inhibition (p=0.02), memory (p=0.04) and mental flexibility (p=0.01). Educational level also affected processing speed, mental flexibility (p=0.01) and working memory (p=0.01). This was more pronounced in OA. In both age groups, hearing status had a strong effect on attentional tasks (p=0.01). In MA, depressive symptoms were more influential on cognitive functioning and on HR-QoL than in OA. Improvement in quality of life (p=0.0002) and working memory (p=0.001) was greater for those with a higher pre-operative depression score.

Conclusion

Speech perception and HR-QoL improved in hearing impaired, independently of age. Pre-operative differences in cognitive performance between OA and MA clearly attenuated 12 months after CI. Impact of comorbidities differed between age groups.

Topic Modeling for Analyzing Patients' Perceptions and Concerns of Hearing Loss on Social Q&A Sites: Incorporating Patients' Perspective

Hearing loss is the most common human sensory deficit, affecting normal communication. Recently, patients with hearing loss or at risk of hearing loss are increasingly turning to the online health community for health information and support. Information on health-related topics exchanged on the Internet is a useful resource to examine patients' informational needs. The ability to understand the patients' perspectives on hearing loss is critical for health professionals to develop a patient-centered intervention. In this paper, we apply Latent Dirichlet Allocation (LDA) on electronic patient-authored questions on social question-and-answer (Q&A) sites to identify patients' perceptions, concerns, and needs on hearing loss. Our results reveal 21 topics, which are both representative and meaningful, and mostly correspond to sub-fields established in hearing science research. The latent topics are classified into five themes, which include "sudden hearing loss", "tinnitus", "noise-induced hearing loss", "hearing aids", "dizziness", "curiosity about hearing loss", "otitis media" and "complications of disease". Our topic analysis of patients' questions on the topic of hearing loss allows achieving a thorough understanding of patients' perspectives, thereby leading to better development of the patient-centered intervention.

Co-occurrence of hearing loss and posttraumatic stress disorder among injured military personnel: a retrospective study

Background

Posttraumatic stress disorder (PTSD) and hearing loss are hallmark public health issues related to military service in Iraq and Afghanistan. Although both are significant individual contributors to disability among veterans, their co-occurrence has not been specifically explored.

Methods

A total of 1179 male U.S. military personnel who sustained an injury between 2004 and 2012 during operations in Iraq or Afghanistan were identified from clinical records. Pre- and postinjury audiometric data were used to define new-onset hearing loss, which was categorized as unilateral or bilateral. Diagnosed PTSD was abstracted from electronic medical records. Logistic regression analysis examined the relationship between hearing loss and PTSD, while adjusting for age, year of injury, occupation, injury severity, injury mechanism, and presence of concussion.

Results

The majority of the study sample were aged 18–25 years (79.9%) and sustained mild-moderate injuries (94.6%). New-onset hearing loss was present in 14.4% of casualties (10.3% unilateral, 4.1% bilateral). Rates of diagnosed PTSD were 9.1, 13.9, and 29.2% for those with no hearing loss, unilateral hearing loss, and bilateral hearing loss, respectively. After adjusting for covariates, those with bilateral hearing loss had nearly three-times higher odds of PTSD (odds ratio = 2.92; 95% CI, 1.47–5.81) compared to those with no hearing loss. Unilateral hearing loss was not associated with PTSD.

Conclusions

Both PTSD and hearing loss are frequent consequences of modern warfare that adversely affect the overall health of the military. Bilateral, but not unilateral, hearing loss was associated with a greater burden of PTSD. This has implications for warfighter rehabilitation and should encourage collaboration between audiology and mental health professionals.

Depression and quality of life in old age: a closer look

Depressive disorders are among the most widespread mental disorders in old age, with negative consequences for quality of life (QOL). Understanding QOL as a multidimensional construct, in this article we have a closer look on what specific aspects are affected by depression. We used a representative sample of the German population (n = 805) and one of individuals diagnosed with depression (n = 106) to compare QOL using the WHOQOL-BREF and the WHOQOL-OLD. Multivariate analysis showed that individuals diagnosed with depression exhibited lower QOL with regard to WHOQOL-BREF-dimensions physical health, psychological, social relationships and global QOL and with regard to WHOQOL-OLD-facets sensory abilities, past, present, and future activities and social participation. In addition, in the regression analysis, there were no significant differences between individuals with and without depression with regard to environment (WHOQOL-BREF), autonomy, death and dying, intimacy and overall (WHOQOL-OLD). Associations between depression and QOL in older age are selective in terms of which aspects of QOL are affected. From a methodological perspective, a multidimensional approach to QOL is recommended. From a clinical perspective, our research highlights those areas of QOL that are relevant for health professionals working with older people and that could be the focus of interventions.

Breaking Down Silos: Interprofessional Collaborative Practice in Humanitarian Audiology

The goal of humanitarian healthcare is to improve health outcomes and patient quality of life in under-resourced areas. One avenue for improvement may be via interprofessional collaborative practice, which allows providers from multiple specialties to work together to promote positive interventions for the communities they serve. The purpose of this article is to provide a general framework for incorporating interprofessional collaborative practice within a humanitarian audiology project.

Attenuation of auditory mismatch negativity in serotonin transporter knockout mice with anxiety-related behaviors

As the first-line antidepressant drugs, selective serotonin reuptake inhibitors (SSRIs) have efficacy in controlling the symptoms of depression. However, adverse events such as anxiety and hearing disorders were usually observed in patients and even healthy volunteers during the initial phase of SSRI administration. Hearing disorders, including auditory hallucination and tinnitus, are not only highly comorbid with mental disorders but also acknowledged factors that induce psychiatric disorders. The pharmacological and neural mechanisms underlying SSRI-induced anxiety and hearing disorders are not clear. In particularly, the methods evaluating hearing disorders are not well established in animal models, limiting the pre-clinical research on its mechanism. In the present study, we examined the mismatch negativity (MMN), a cognitive component of auditory event-related potential (ERP), to evaluate the hearing process of auditory cortex in mice. Under the acute administration of citalopram, a widely used SSRI, the anxiety-related behaviors and reduced MMN were observed in mice. Serotonin transporter (SERT) is a potential target of SSRIs. The anxiety-related behaviors and reduced MMN were also observed in SERT knockout mice, implying the role of SERT in anxiety and hearing disorders induced by SSRIs. Meanwhile, the auditory brainstem response and initial components of auditory ERP were kept intact in SERT knockout mice, suggesting that hearing neural pathway is less affected by serotonergic system. Our study suggests that the SERT deficient mice might represent a useful animal model in the investigation of the anxiety and hearing disorders during the SSRI treatment.

Exploring the recruitment, ethical considerations, conduct and information dissemination of an audiology trial: a pretrial qualitative study (q-COACH)

INTRODUCTION

Randomised controlled trials (RCTs), while still considered the gold standard approach in medical research, can encounter impediments to their successful conduct and the dissemination of results. Pretrial qualitative research can usefully address some of these impediments, including recruitment and retention, ethical conduct, and preferred methods of dissemination. However, pretrial qualitative work is rarely undertaken in audiology. The Comparison of outcomes with hearing aids and cochlear implants in adults with moderately severe-to-profound bilateral sensorineural hearing loss (COACH) is a proposed RCT aiming to clarify when hearing aids (HAs) or cochlear implants (CIs) are the most suitable for different degrees of hearing loss and for which kinds of patients. q-COACH is a pretrial, qualitative study examining stakeholders' experiences of HAs and CIs, current clinical practices and stakeholders' perspectives of the design, conduct and dissemination plans for the proposed COACH study.

METHODS

Twenty-four participants including general practitioners, audiologists, adult HA users, and adult support networks undertook either semi-structured individual or paired interviews and completed demographic questionnaires. Data were analysed thematically.

RESULTS

Four key themes arose from this study: 1) rethinking sampling and recruitment strategies, 2) ethical considerations, 3) refining trial conduct, and 4) interconnected, appropriate and accessible methods of results dissemination.

CONCLUSIONS

This qualitative investigation identified key considerations for the proposed RCT design, conduct and dissemination to help with successful implementation of COACH, and to indicate a plan of action at all RCT stages that would be acceptable to potential participants. By drawing on the perspectives of multiple key stakeholders and including a more general discussion of their experience and opinions of hearing loss, hearing device use and service availability, the study revealed experiential and ethical paradigms in which stakeholders operate. In so doing, q-COACH has exposed the benefits of preliminary qualitative investigations that enable detailed and rich understandings of the phenomenon at stake, forestalling problems and improving the quality of trial design, conduct and dissemination, while informing future RCT development discussions.

Incident Hearing Loss and Comorbidity: A Longitudinal Administrative Claims Study

Importance

Because hearing loss is highly prevalent and treatable, determining its association with morbidity has major public health implications for disease prevention and the maintenance of health in adults with hearing loss.

Objective

To investigate the association between the diagnosis of incident hearing loss and medical comorbidities in adults 50 years or older.

Design, Setting, and Participants

Retrospective, propensity-matched cohort study using administrative claims data from commercially insured and Medicare Advantage members in a geographically diverse US health plan. Adults 50 years or older with claims for services rendered from January 1, 2000, to December 31, 2016, were observed for 2 (n = 154 414), 5 (n = 44 852), and 10 (n = 4728) years. This research was conceptualized and data were analyzed between September 2016 and November 2017.

Exposures

A claim for incident hearing loss is defined as 2 claims for hearing loss within 2 consecutive years without evidence of hearing device use, excluding claims for sudden hearing loss or hearing loss secondary to medical conditions.

Main Outcomes and Measures

Incident claims for dementia, depression, accidental falls, nonvertebral fractures, acute myocardial infarction, and stroke.

Results

After cohort matching, 48% of participants were women (n = 74 464), 61% were white (n = 93 442), and 31% (n = 48 056) were Medicare Advantage insured, with a mean (SD) age of 64 (10) years. In a multivariate-adjusted modified Poisson regression with robust standard errors, relative associations were strongest for dementia (relative risk at 5 years, 1.50; 95% CI, 1.38-1.64) and depression (relative risk at 5 years, 1.41; 95% CI, 1.26-1.58). The absolute risk of all outcomes was greater in persons with hearing loss than in those without hearing loss at all times, with the greatest risk difference observed at 10 years for all outcomes. The 10-year risk attributable to hearing loss was 3.20 per 100 persons (95% CI, 1.76-4.63) for dementia, 3.57 per 100 persons (95% CI, 1.67-5.47) for falls, and 6.88 per 100 persons (95% CI, 4.62-9.14) for depression.

Conclusions and Relevance

In this large observational study using administrative claims data, incident untreated hearing loss was associated with greater incident morbidity than no hearing loss across a range of health conditions. Future studies are needed to elucidate the mechanisms underlying these associations and to determine if treatment for hearing loss could reduce the risk of comorbidity.

Common mental illness in people with sensory impairment: results from the 2014 adult psychiatric morbidity survey

BACKGROUND

People with sensory impairments may be at increased risk of depression and anxiety but experience barriers to accessing treatment.

AIMS

To investigate whether people with sensory impairment have more depressive and anxiety symptoms than people without, whether this is mediated by social functioning and whether they report greater non-treatment.

METHOD

We analysed data from the English 2014 Adult Psychiatric Morbidity Survey using regression models, with the Clinical Interview Schedule-Revised (CIS-R) score as the primary outcome and self-reported hearing and vision impairment as exposures. A secondary outcome was self-reported receipt of mental health diagnosis and treatment. We used structural equation modelling to assess for mediation by social functioning.

RESULTS

A total of 19.0% of people with hearing impairment, and 30.9% and 24.5% with distance and near visual impairments, respectively, had clinically significant psychological morbidity. Adjusted mean CIS-R score was 1.86 points higher in people with hearing impairment compared with those without (95% CI 1.30-2.42, P<0.001). People with distance and near vision impairment had mean CIS-R scores 3.61 (95% CI 2.58-4.63, P<0.001) and 2.74 (95% CI 2.12-3.37, P<0.001) points higher, respectively, than those without. Social functioning accounted for approximately 50% of these relationships between sensory impairment and psychological morbidity. We found no evidence of an increased treatment gap for people with sensory impairment.

CONCLUSIONS

Social functioning, a potentially modifiable target, may mediate an association between sensory impairment and depressive and anxiety symptoms.

Addressing clinical equipoise for hearing devices: the qualitative COACH (q-COACH) study protocol for Australian stakeholder involvement in the design of a randomised controlled trial

INTRODUCTION

Hearing loss is a common chronic problem which can be effectively managed with hearing devices. At present, only a limited number of people with hearing loss use hearing aids (HAs) and cochlear implants (CIs) to improve hearing and sound quality and enhance quality of life. Clinical equipoise, by which we mean healthcare professional uncertainty about which treatment options are the most efficacious due to the lack of evidence-based information, can lead to inconsistent and poorly informed referral processes for hearing devices.A randomised controlled trial (RCT) that offers high-quality, generalisable information is needed to clarify which hearing device (HA or CI) is more suitable for different degrees of hearing loss and for which kinds of patients. Qualitative research can improve this RCT, by gathering the information on patient and provider perspectives, attitudes and values, which can inform design, conduct and information dissemination, either during preparatory stages of an intervention, or as a fully integrated methodology. The Comparison of Outcomes with hearing Aids and Cochlear implants in adults with moderately severe-to-profound bilateral sensorineural Hearing loss (COACH) study is being planned as an RCT with a qualitative arm (the qualitative COACH study, q-COACH), acting as a pretrial intervention examining views of HAs, CIs, equipoise and the impetus for an RCT of this nature.

METHODS AND ANALYSIS

The q-COACH study involves semistructured interviews and a demographic questionnaire which will be collected from four participant cohorts: General Practitioners (GPs) and Ear, Nose and Throat Surgeons (ENTs); audiologists; adult HA users and their support networks. Data will be analysed thematically and through descriptive statistics.

ETHICS AND DISSEMINATION

Macquarie University Human Research Ethics Committee, Australia, granted ethical approval (no. 5201833514848). Peer-reviewed journal articles, research conferences and a final report will present study findings.

Depression in elderly patients with hearing loss: current perspectives

Hearing loss (HL) is highly common in older adulthood, constituting the third most prevalent chronic health condition in this population. In addition to posing a substantial burden to disease and negatively impacting quality of life, an emerging literature highlights that HL is associated with unipolar depression including among older adults. This review outlines evidence examining the HL and depression relationship as well as clinical implications for assessment and treatment of comorbid depression and HL. Although prevalence estimates of comorbid depression in HL vary, as many as 1 in 5 experience clinically relevant depression symptoms. Both cross-sectional and longitudinal studies indicate that HL is related to increased unipolar depression symptoms, although the strength of the association varies between studies. A range of methodological variations, such as inclusion age, severity of HL and assessment of depression, likely underpin this heterogeneity. Overall, however, the evidence clearly points to an association of HL with clinically relevant depression symptoms. The association with the diagnosis of major depression disorder remains less clear and under-researched. HL is also associated with a range of other poor mental health outcomes in older adults, including anxiety and suicidal ideation, and predicts poorer cognitive functioning. Accordingly, assessment and treatment of comorbid depression in HL is pertinent to promote mental well-being among older adults. Currently, evidence regarding best practice for treating depression in HL remains scant. Preliminary evidence indicates that audiological rehabilitation, including use of hearing aids, as well as community-based hearing interventions can also improve mental health. Psychological intervention that enhances communication skills and addresses coping strategies might also be beneficial for this population. Additionally, evidence suggests that online interventions are feasible and may circumvent communication difficulties in therapy associated with HL. Due to poor help-seeking among this population, an enhanced focus on specific and targeted assessment and treatment is likely necessary to ensure reduced mental health burden among older adults with HL.

Association of hearing loss with depression, anxiety and stress in patients suffering from Chronic Suppurative Otitis Media

OBJECTIVE

To study the correlation of hearing loss with depression, anxiety and stress in patients suffering from chronic suppurative otitis media in local population of Pakistan.

METHODS

This is a cross-sectional study conducted from May to September 2018 at tertiary care hospital of Karachi. One hundred and twenty patients of chronic suppurative otitis media were divided into three groups: Group-1 (maintained on ciprofloxacin), Group-2 (maintained on co-amoxicillin) and Group-3 (did not subject to the treatment).The measurement of hearing loss was carried out by pure tone audiometry (PTA) and the depression, anxiety and stress were scored taking depression, anxiety and stress scale (DASS) as tool. To observe the effect of hearing loss on different groups one way ANOVA was applied and Spearman correlation was used to find correlation of depression with hearing loss.

RESULTS

There was no significant difference found for hearing loss and severity among the groups treated with ciprofloxacin, co-amoxicillin and not maintained on antibiotic therapy. Positive correlations found between hearing loss and depression, anxiety and stress in patients of the three groups.

CONCLUSION

Depression induced by hearing loss as a result of CSOM in patients need to be monitored during and after treatment and scored so that can be treated by counseling and antidepressant (if required). Information regarding this topic on population of Pakistan will be helpful for health care takers and policy makers to manage mental stress with hearing loss in CSOM.

Pure Tone Audiometry Threshold Changes for 10 Years in the Same Individuals of General Population: A Retrospective Cohort Study

Objectives:

The objectives of this study were to measure the changes in hearing thresholds in the same individuals during a period of 10 years and suggest a clinical reference for the threshold changes by aging.

Methods:

In this retrospective cohort study, we used regular health checkup data including 2 pure tone audiometry results with a 10-year interval in the same individuals from 1288 subjects. The subjects’ data including demographics, smoking habits, and the diagnosis of chronic diseases were used.

Results:

Age, male gender, smoking, and osteoporosis were identified as factors affecting age-related hearing loss (ARHL). The sole effect of aging on ARHL for 10 years according to age groups and genders was as follows: a loss of 1.4 dB in 20s, 4.0 dB in 30s, 5.0 dB in 40s, 8.2 dB in 50s, and 11.2 dB in 60s of males compared to a loss of 2.3 dB in 20s, 2.9 dB in 30s, 5.1 dB in 40s, 6.5 dB in 50s, and 9.4 dB in 60s of females.

Conclusions:

We could demonstrate the actual effect of aging on ARHL, and it can be used as a clinical reference. Hearing ability decreases more in males than females but seems to decrease exponentially with age in both males and females.

Sensory loss and suicide ideation in older adults: findings from the Three-City cohort study

ABSTRACTObjectives:To examine the longitudinal risk of vision loss (VL) or hearing loss (HL) for experiencing suicidal ideation in older adults.

DESIGN

The Three-City study, examining data from three waves of follow-up (2006-2008, 2008-2010, and 2010-2012).

SETTING

Community-dwelling older French adults.

PARTICIPANTS

N = 5,438 adults aged 73 years and over.

MEASUREMENTS

Suicidality was assessed by the Mini-International Neuropsychiatric Interview, Major Depressive Disorder module. Mild VL was defined as Parinaud of 3 or 4 and severe VL as Parinaud &gt;4. Mild HL was self-reported as difficulty understanding a conversation and severe HL as inability to understand a conversation.

RESULTS

Severe VL was associated with an increased risk of suicidal ideation at baseline (OR = 1.59, 95% CIs = 1.06-2.38) and over five years (OR = 1.65, 95% CIs = 1.05-2.59). Mild and severe HL were associated with an increased risk of suicidal ideation, both at baseline (OR = 1.29, 95% CIs = 1.03-1.63; OR = 1.78, 95% CIs = 1.32-2.40) and over five years (OR = 1.47, 95% CIs = 1.17-1.85; OR = 1.97, 95% CIs = 1.44-2.70).

CONCLUSION

Sensory losses in late life pose a risk for suicidal ideation. Suicidality requires better assessment and intervention in this population.

The relationship between hearing loss in older adults and depression over 12 years: Findings from the Three-City prospective cohort study

OBJECTIVE

The present study aims to examine the longitudinal relationship between hearing loss (HL) with depression in older adults over 12 years of follow-up.

METHOD

Eight thousand three hundred forty-four French community-dwelling adults aged 65 and above participated in the Three-City prospective population-based study. Baseline relationships between self-reported mild and severe HL with depression-assessed by both the Mini International Neuropsychiatric Interview and by the Centre for Epidemiology Studies Depression scale-were explored using logistic regression analyses. Logistic mixed models assessed whether baseline HL was associated with incident depression diagnosis or symptom onset over 12 years in those who were depression-free at baseline.

RESULTS

At baseline, mild and severe HL were associated with depression symptoms as assessed by the CESD (OR = 1.29, 95% CIs 1.14-1.47; OR = 1.51, 95% CIs 1.22-1.87; respectively), although only mild HL was significantly related to major depression diagnosis (OR = 1.51, 95% CIs 1.07-2.12). Over 12 years, mild and severe HL were associated with incident depression as assessed by the CESD in those without depression at baseline (OR = 1.36, 95% CIs 1.15-1.61; OR = 1.69, 95% CIs 1.15-2.30; respectively), but was not associated with a major depression diagnosis.

CONCLUSIONS

Both mild and severe thresholds of HL are associated with depression symptoms over time, but not with incident diagnosis of major depression. Improved and ongoing detection of subthreshold depression amongst older adults with HL may improve quality of life for this population.

Longitudinal Pure-Tone Threshold Changes in the Same Subjects: Analysis of Factors Affecting Hearing

OBJECTIVES

To investigate the change of hearing threshold over time and analyze factors that could affect hearing, this longitudinal study of pure-tone threshold changes in the same subjects at a 9-year interval was performed.

STUDY DESIGN

Retrospective longitudinal study in a single center (n = 1,978).

METHODS

A total of 1,978 subjects were included; they received pure-tone audiometry at a 9-year interval. The degree of the threshold changes was examined and compared between age groups. The subjects' data, such as the level of cholesterol, were analyzed to find risk factors on hearing.

RESULTS

The average of the threshold changes was 3.35 dB in the 20s to 30s; 4.38 dB in the 30s to 40s; 5.75 dB in the 40s to 50s; 7.21 dB in the 50s to 60s; and 10.00 dB in the 60s to 70s (all P < 0.05). If the low-density lipoprotein cholesterol (LDL-C) was maintained below 100 mg/dl, the difference in the weighted four-frequency average was 5.45 dB, whereas it was 6.15 dB in the subjects whose LDL-C was over 100 mg/dl (P = 0.032, age-adjusted). In current smokers, the thresholds increased more than in never- or ex-smokers (P = 0.026 in the weighted four-frequency average and P = 0.011 at 8,000 Hz, age-adjusted).

CONCLUSION

The degree of the threshold changes exhibited an exponential increase with age. Cessation of smoking is advisable to prevent increased aggravation of hearing. Strict management of the low-density lipoprotein cholesterol may have a positive effect on hearing.

Relationships between the neighborhood environment and depression in older adults: a systematic review and meta-analysis

ABSTRACTBackground:While depression is a growing public health issue, the percentage of individuals with depression receiving treatment is low. Physical and social attributes of the neighborhood may influence the level of depressive symptoms and the prevalence of depression in older adults.

METHODS

This review systematically examined the literature on neighborhood environmental correlates of depression in older adults. Findings were analyzed according to three depression outcomes: depressive symptoms, possible depression, and clinical depression. Based on their description in the article, environmental variables were assigned to one of 25 categories. The strength of evidence was statistically quantified using a meta-analytical approach with articles weighted for sample size and study quality. Findings were summarized by the number of positive, negative, and statistically non-significant associations by each combination of environmental attribute - depression outcome and by combining all depression outcomes.

RESULTS

Seventy-three articles met the selection criteria. For all depression outcomes combined, 12 of the 25 environmental attribute categories were considered to be sufficiently studied. Three of these, neighborhood socio-economic status, collective efficacy, and personal/crime-related safety were negatively associated with all depression outcomes combined. Moderating effects on associations were sparsely investigated, with 52 articles not examining any. Attributes of the physical neighborhood environment have been understudied.

CONCLUSION

This review provides support for the potential influence of some neighborhood attributes on population levels of depression. However, further research is needed to adequately examine physical attributes associated with depression and moderators of both social and physical neighborhood environment attribute - depression outcome associations.

Impact of chemotherapy-induced neurotoxicities on adult cancer survivors' symptom burden and quality of life

PURPOSE

Limited information is available on the impact of chemotherapy (CTX)-induced neurotoxicity on adult survivors' symptom experience and quality of life (QOL). Purposes were to describe occurrence of hearing loss and tinnitus and evaluate for differences in phenotypic characteristics and measures of sensation, balance, perceived stress, symptom burden, and QOL between survivors who received neurotoxic CTX and did (i.e., neurotoxicity group) and did not (i.e., no neurotoxicity group) develop neurotoxicity. Neurotoxicity was defined as the presence of chemotherapy-induced neuropathy (CIN), hearing loss, and tinnitus. Survivors in the no neurotoxicity group had none of these conditions.

METHODS

Survivors (n = 609) completed questionnaires that evaluated hearing loss, tinnitus, stress, symptoms, and QOL. Objective measures of sensation and balance were evaluated.

RESULTS

Of the 609 survivors evaluated, 68.6% did and 31.4% did not have CIN. Of the survivors without CIN, 42.4% reported either hearing loss and/or tinnitus and 48.1% of the survivors with CIN reported some form of ototoxicity. Compared to the no neurotoxicity group (n = 110), survivors in the neurotoxicity group (n = 85) were older, were less likely to be employed, had a higher comorbidity burden, and a higher symptom burden, higher levels of perceived stress, and poorer QOL (all p < .05).

CONCLUSIONS

Findings suggest that CIN, hearing loss, and tinnitus are relatively common conditions in survivors who received neurotoxic CTX.

IMPLICATIONS FOR CANCER SURVIVORS

Survivors need to be evaluated for these neurotoxicities and receive appropriate interventions. Referrals to audiologists and physical therapists are warranted to improve survivors' hearing ability, functional status, and QOL.

Hearing loss and tinnitus in survivors with chemotherapy-induced neuropathy

PURPOSE

The purpose of this study was to evaluate for differences in demographic, clinical, and pain characteristics, as well as measures of sensation, balance, perceived stress, symptom burden, and quality of life (QOL) among survivors who received neurotoxic chemotherapy (CTX) and who reported only chemotherapy-induced neuropathy (CIN, n = 217), CIN and hearing loss (CIN/HL, n = 69), or CIN, hearing loss, and tinnitus (CIN/HL/TIN, n = 85). We hypothesized that as the number of neurotoxicities increased, survivors would have worse outcomes.

METHODS

Survivors were recruited from throughout the San Francisco Bay area. Survivors completed self-report questionnaires for pain and other symptoms, stress and QOL. Objective measures were assessed at an in person visit.

RESULTS

Compared to survivors with only CIN, survivors with all three neurotoxicities were less likely to be female and less likely to report child care responsibilities. In addition, survivors with all three neurtoxicities had higher worst pain scores, greater loss of protective sensation, and worse timed get up and go scores. These survivors reported higher state anxiety and depression and poorer QOL. For some outcomes (e.g., longer duration of CIN, self-reported balance problems), significantly worse outcomes were found for the survivors with CIN/HL and CIN/HL/TIN compared to those with only CIN.

CONCLUSIONS

Our findings suggest that compared to survivors with only CIN, survivors with CIN/HL/TIN are at increased risk for the most severe symptom burden, significant problems associated with sensory loss and changes in balance, as well as significant decrements in all aspects of QOL.

Applications of direct-to-consumer hearing devices for adults with hearing loss: a review

Background

This systematic literature review is aimed at investigating applications of direct-to-consumer hearing devices for adults with hearing loss. This review discusses three categories of direct-to-consumer hearing devices: 1) personal sound amplification products (PSAPs), 2) direct-mail hearing aids, and 3) over-the-counter (OTC) hearing aids.

Method

A literature review was conducted using EBSCOhost and included the databases CINAHL, MEDLINE, and PsycINFO. After applying prior agreed inclusion and exclusion criteria, 13 reports were included in the review.

Results

Included studies fell into three domains: 1) electroacoustic characteristics, 2) consumer surveys, and 3) outcome evaluations. Electroacoustic characteristics of these devices vary significantly with some meeting the stringent acoustic criteria used for hearing aids, while others producing dangerous output levels (ie, over 120-dB sound pressure level). Low-end (or low-cost) devices were typically poor in acoustic quality and did not meet gain levels necessary for most adult and elderly hearing loss patterns (eg, presbycusis), especially in high frequencies. Despite direct-mail hearing aids and PSAPs being associated with lower satisfaction when compared to hearing aids purchased through hearing health care professionals, consumer surveys suggest that 5%–19% of people with hearing loss purchase hearing aids through direct-mail or online. Studies on outcome evaluation suggest positive outcomes of OTC devices in the elderly population. Of note, OTC outcomes appear better when a hearing health care professional supports these users.

Conclusion

While some direct-to-consumer hearing devices have the capability to produce adverse effects due to production of dangerously high sound levels and internal noise, the existing literature suggests that there are potential benefits of these devices. Research of direct-to-consumer hearing devices is limited, and current published studies are of weak quality. Much effort is needed to understand the benefits and limitations of such devices on people with hearing loss.

Unilateral Cochlear Implantation Reduces Tinnitus Loudness in Bimodal Hearing: A Prospective Study

Perceptive and receptive aspects of subjective tinnitus like loudness and tinnitus-related distress are partly independent. The high percentage of hearing loss in individuals with tinnitus suggests causality of hearing impairment particularly for the tinnitus percept, leading to the hypothesis that restoration of auditory input has a larger effect on tinnitus loudness than on tinnitus-related distress. Furthermore, it is assumed that high levels of depression or anxiety prevent reductions of tinnitus loudness and distress following restoration of activity in the cochlea. This prospective study investigated the influence of unilateral cochlear implant (CI) on tinnitus in 19 postlingually deafened adults during 6 months following implantation. All had bimodal provision with the other ear being continuously supported by a hearing aid. On the day before CI implantation (T1, T2), and at about 3 and 6 months postsurgery (T3, T4), participants were questioned about their current tinnitus. Loudness was rated on a Numeric Rating Scale, distress was assessed by the TQ12 Tinnitus Questionnaire, and depression and anxiety were recorded with the Hospital Anxiety and Depression Scale. At T2, 79% experienced tinnitus, one participant developed tinnitus after implantation. Following implantation, tinnitus loudness was reduced significantly by 42%, while reductions in tinnitus-related distress (−24%), depression (−20%), and anxiety (−20%) did not attain statistical significance. Significant correlations existed between tinnitus measures, and between postimplantation tinnitus-related distress and anxiety and depression scores. Moreover, improvement of hearing in the CI ear was significantly correlated with reduction in tinnitus loudness. A new aspect of this study is the particular influence of CI provision on perceptive aspects of preexisting tinnitus (hypothesis 1), with the effect size regarding postimplant reduction of perceived tinnitus loudness (1.40) being much larger than effect sizes on the reduction of tinnitus-related distress (0.38), depression (0.53), and anxiety (0.53). Contrary to expectation both tinnitus measures reduce even in the majority of CI recipients with increased levels of anxiety or depression. This suggests that reduction of the tinnitus signal by restoring activity in the cochlea cannot be entirely compensated for by central tinnitus mechanisms and results in a reduction of perceptive and less so of reactive aspects of subjective tinnitus.
