Abstract
OBJECTIVE The aim of the study was to develop a Markov model and apply it for the evaluation of three different treatment scenarios for adult patients with severe to profound bilateral sensorineural hearing loss. STUDY DESIGN Prospective Observational Study. SETTINGS Hospital. PATIENTS A clinical group of 22 adult patients (59.1% men, 40.9% women) aged from 59.13 ± 8.9 years were included in the study. The study comprised two arms: patients in group 1 received the second cochlear implant one to three months after the first implant; while patients in group 2 got the second cochlear implant approximately one year after the first implant. MAIN OUTCOME MEASURES All participants were first asked to complete an AQoL-8D questionnaire. For the cost-effectiveness analyses, a Markov model analyzed as microsimulation was developed to compare the different treatment options. RESULTS The analyses show that bilateral cochlear implantation strategies are cost-effective compared to the 'no treatment' alternative when having a 10-year model time horizon. When all three model scenarios are compared, the bilateral simultaneous cochlear implantation strategy (Scenario 3) compared to the 'no treatment' option is even more cost-effective than the Scenarios 1 and 2, compared with the 'no treatment' alternative. CONCLUSIONS The model results summarize that bilateral (sequential and simultaneous) cochlear implantation that are represented in the model scenarios, are cost-effective strategies for Polish adult patients with bilateral severe to profound sensorineural hearing loss.

Abstract
OBJECTIVES To investigate the potential association between beta blocker use and hearing ability in adults and to discern whether this effect is dose-dependent. DESIGN Cross-sectional analyses. Multiple linear regression was performed with hearing ability as the dependent variable and beta blocker use as the independent variable. The independent variable was classified into three dose categories for secondary analysis. Adjustments were made for age, gender, educational level, and tobacco smoking status. STUDY SAMPLE 1636 adults, 75 of whom reported being on beta blockers, from the internet-based Netherlands Longitudinal Study on Hearing (NL-SH). RESULTS No significant association was found between beta blocker use and hearing ability in noise. In the adjusted regressions, beta blocker use changed the speech reception threshold in noise (SRT) by -0.04 dB signal-to-noise ratio (SNR) (95%CI [-0.67 to 0.58], p = 0.890). Medium dose beta blocker use changed SRT by -0.42 dB SNR (95%CI [-1.38 to 0.71], p = 0.433), while a high dose changed it by -0.26 dB SNR (95%CI [-1.74 to 1.4], p = 0.767). CONCLUSIONS No evidence was found for beta blocker-induced changes in hearing ability. Future studies on this topic should favour case-control and cohort study designs, while focussing on a hypertensive population to minimise confounding by indication.

Abstract
BACKGROUND Patient- and caregiver-reported 23-item SymTrak scales were validated for monitoring clinically actionable symptoms and impairments associated with multiple chronic conditions (MCCs) in older adults. Items capture physical and emotional symptoms and impairments in physical and cognitive functioning. An abbreviated SymTrak is desirable when response burden is a concern. OBJECTIVE Develop and validate the 8-item SymTrak. DESIGN AND PARTICIPANTS Secondary analysis of SymTrak validation study; 600 participants (200 patient-caregiver dyads; 200 patients without an identified caregiver). MAIN MEASURES Demographic questions, SymTrak, and Health Utility Index Mark 3 (HUI3). KEY RESULTS SymTrak-8 demonstrated good fit to a one-factor model using confirmatory factor analysis (CFA). Concurrent criterion validity was supported by high standardized linear regression coefficients (STB) between baseline SymTrak-8 total score (independent variable) and baseline HUI3 preference-based overall HRQOL utility score (dependent variable; 0 = death, 1 = perfect health), after adjusting for demographics, comorbid conditions, and medications, with strength comparable to SymTrak-23 (STB = - 0.81 and - 0.84, respectively, for SymTrak-8 and SymTrak-23, when patient-reported; and - 0.60 and - 0.62, respectively, when caregiver-reported). Coefficient alpha (0.74; 0.76) and 24-h test-retest reliability (0.83; 0.87) were high for SymTrak-8 for patients and caregivers, respectively. The convergent correlation between brief and parent SymTrak scales was high (0.94). SymTrak-8 demonstrated approximate normality and a linear relationship with SymTrak-23 and HUI3. Importantly, a 3-month change in SymTrak-8 was sensitive to detecting the criterion (3-month reliable change categories; improved, stable, declined in HUI3 overall utility), with results comparable to SymTrak-23. CONCLUSIONS SymTrak-8 total score demonstrates internal reliably, test-retest reliability, criterion validity, and sensitivity to change that are comparable to SymTrak-23. Thus, patient- or caregiver-reported SymTrak-8 is a viable option for identifying and monitoring the aggregate effect of symptoms and functional impairments in patients with multimorbidity when response burden is a concern.

Abstract
Behavioral studies on auditory deviance detection in patients with Parkinson's disease (PD) have reported contradictory results. The primary aim of this study was to investigate auditory deviance detection of multiple auditory features in patients with PD by means of objective and reliable electroencephalographic (EEG) measurements. Twelve patients with early-stage PD and twelve age- and gender-matched healthy controls (HCs) were included in this study. Patients with PD participated without their regular dopaminergic medication. All subjects underwent an audiometric screening and performed a passive multi-feature mismatch negativity (MMN) paradigm. Repeated-measures analysis of variance (ANOVA) demonstrated no significant differences between patients with PD and HCs regarding MMN mean amplitude and latency for frequency, duration and gap deviants. Nevertheless, a trend towards increased MMN mean amplitude and latency was found in response to intensity deviants in patients with PD compared to HCs. Increased intensity MMN amplitude may indicate that more neural resources are allocated to the processing of intensity deviances in patients with PD compared to HCs. The interpretation of this intensity-specific MMN alteration is further discussed in the context of a compensatory mechanism for auditory intensity processing and involuntary attention switching in PD.

Abstract
Purpose Several studies have demonstrated increased auditory thresholds in patients with Parkinson's disease (PD) based on subjective tonal audiometry. However, the pathophysiological mechanisms underlying auditory dysfunction in PD remain elusive. The primary aim of this study was to investigate cochlear and olivocochlear function in PD using objective measurements and to assess the effect of dopaminergic medication on auditory function. Method Eighteen patients with PD and 18 gender- and age-matched healthy controls (HCs) were included. Patients with PD participated in medication on and off conditions. Linear mixed models were used to determine the effect of PD on tonal audiometry, transient evoked and distortion product otoacoustic emissions (OAEs), and efferent suppression (ES). Results Tonal audiometry revealed normal auditory thresholds in patients with PD for their age across all frequencies. OAE signal amplitudes demonstrated a significant interaction effect between group (PD vs. HC) and frequency, indicating decreased OAEs at low frequencies and increased OAEs at high frequencies in patients with PD. No significant differences were found between patients with PD and HCs regarding ES. In addition, no significant effect of medication status was found on auditory measurements in patients with PD. Conclusions Altered OAEs support the hypothesis of cochlear alterations in PD. No evidence was found for the involvement of the medial olivocochlear system. Altogether, OAEs may provide an objective early indicator of auditory alterations in PD and should complement subjective tonal audiometry when assessing and monitoring auditory function in PD.

Bilateral age-related atrophy in the planum temporale is associated with vowel discrimination difficulty in healthy older adults. Hear Res 2021; 406:108252.

Abstract
In this study we investigated the association between age-related brain atrophy and behavioural as well as electrophysiological markers of vowel perception in a sample of healthy younger and older adults with normal pure-tone hearing. Twenty-three older adults and 27 younger controls discriminated a set of vowels with altered second formants embedded in consonant-vowel syllables. Additionally, mismatch negativity (MMN) responses were recorded in a separate oddball paradigm with the same set of stimuli. A structural magnet resonance scan was obtained for each participant to determine cortical architecture of the left and right planum temporale (PT). The PT was chosen for its function as a major processor of auditory cues and speech. Results suggested that older adults performed worse in vowel discrimination despite normal-for-age pure-tone hearing. In the older group, we found evidence that those with greater age-related cortical atrophy (i.e., lower cortical surface area and cortical volume) in the left and right PT also showed weaker vowel discrimination. In comparison, we found a lateralized correlation in the younger group suggesting that those with greater cortical thickness in only the left PT performed weaker in the vowel discrimination task. We did not find any associations between macroanatomical traits of the PT and MMN responses. We conclude that deficient vowel processing is not only caused by pure-tone hearing loss but is also influenced by atrophy-related changes in the ageing auditory-related cortices. Furthermore, our results suggest that auditory processing might become more bilateral across the lifespan.

Abstract
Objectives We evaluated changes in income levels in a hearing-impaired population. Methods The study subjects were selected from the Korean National Health Insurance Service-Health Screening Cohort data from 2002 to 2015 of Koreans ≥40 years old. In total, 5,857 hearing-impaired subjects were matched with 23,428 comparison participants. Differences between the initial income level and income levels at 1, 2, 3, 4, and 5 years post-enrollment were compared between the hearing-impaired and comparison groups. The interaction of time and hearing impairment/comparison was estimated. Results Both the hearing-impaired group and the comparison group showed increased income levels over time. In the hearing-impaired group, the income levels at 4 and 5 years post-enrollment were higher than the initial income level (each P<0.001). In the comparison group, the income levels of all the participants after 1–5 years were higher than the initial income level (each P<0.001). The interaction of time and hearing impairment was statistically significant (P=0.021). Conclusion The increase in income over time was relatively lower in the hearing-impaired adult population; therefore, the income gap widened between this population and the normal-hearing population.

Abstract
INTRODUCTION Risk factors for cardiovascular disease (CVD) are associated with sensorineural hearing loss. CVD risk factors are known to cluster and interact, thereby increasing the cumulative risk for CVD. Previously, using the database of the Netherlands Longitudinal Study on Hearing (NL-SH), an association was found between a history of smoking and an increased decline in speech recognition in noise over 10 years of follow-up. Prospectively limited data are available on the association between CVD risk factors, interactions of these risk factors, and hearing loss. In this study, data from the NL-SH were used to study the association between CVD risk factors and speech recognition in noise longitudinally. METHODS Baseline, 5-year, and 10-year follow-up data of the NL-SH were included. The NL-SH is a web-based prospective cohort study which started in 2006. Participants were aged 18-70 years at baseline. Speech recognition in noise was determined with an online digit-triplet speech-in-noise test. In addition, participants completed online questionnaires on demographic, lifestyle, and health-related characteristics. The association of the ability to recognize speech in noise with CVD risk factors (i.e., obesity, rheumatoid arthritis [RA], hypertension, diabetes mellitus, and dyslipidemia) was analyzed longitudinally. We also analyzed the interaction between these risk factors (including age, sex, and history of smoking) and speech recognition in noise. RESULTS None of the CVD risk factors or interactions of 2 CVD risk factors was significantly associated with a decline in SRT over time. Obesity (p = 0.016), RA (p = 0.027), and hypertension (p = 0.044) were associated with overall higher (more unfavorable) SRTs. No overall interactions between CVD risk factors were found. CONCLUSION Obesity, RA, and hypertension were overall associated with a higher SRT, but no longitudinal associations between these or other CVD factors with SRTs were found. Also, no interactions between 2 CVD risk factors and SRTs were found. Although no longitudinal associations between CVD risk factors and decline in SRTs were found, clinicians should be alert about the concurrent association between CVD risk factors and hearing loss.

Abstract
OBJECTIVE To estimate the global costs of hearing loss in 2019. DESIGN Prevalence-based costing model. STUDY SAMPLE Hearing loss data from the 2019 Global Burden of Disease study. Additional non-hearing related health care costs, educational support, exclusion from the labour force in countries with full employment and societal costs posed by lost quality of life were determined. All costs were reported in 2019 purchasing power parity (PPP) adjusted international dollars. RESULTS Total global economic costs of hearing loss exceeded $981 billion. 47% of costs were related to quality of life losses, with 32% due to additional costs of poor health in people with hearing loss. 57% of costs were outside of high-income countries. 6.5% of costs were for children aged 0-14. In scenario analysis a 5% reduction in prevalence of hearing loss would reduce global costs by $49 billion. CONCLUSION This analysis highlights major economic consequences of not taking action to address hearing loss worldwide. Small reductions in prevalence and/or severity of hearing loss could avert substantial economic costs to society. These cost estimates can also be used to help in modelling the cost effectiveness of interventions to prevent/tackle hearing loss and strengthen the case for investment.

Abstract
OBJECTIVE Hearing loss is associated with multiple physical, cognitive, and psychosocial co-morbidities. Achievement of safe healthcare in the context of these complex co-morbidities necessitates accurate hearing and coordination across specialties. This paper discusses the potentials for and barriers to an interprofessional approach to integrating hearing screening and treatment across all healthcare settings. DESIGN The paper reviews the relationship between hearing loss and other health care concerns to emphasise the need for an inclusive, coordinated, interprofessional approach; discusses interprofessional and patient/family centred coordinated care as essential to achieving quality care; and introduces the Age Friendly Health System initiative as a framework that could be leveraged to move towards comprehensive hearing healthcare. RESULTS The literature highlights prior work identifying gaps in quality care and the need for new and innovative approaches to evolve interdisciplinary and interprofessional collaborations to achieve comprehensive healthcare. The literature also provides support for using the Age-Friendly initiative as a point of leverage. CONCLUSION Bringing together thought leaders from the health care provider community, World Health Organisation, age-friendly cities movement, and field of architecture to coordinate the integration of hearing healthcare into Age Friendly Health Systems initiatives has potential to achieve comprehensive hearing healthcare across healthcare settings.

Abstract
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.

Risk of hearing loss in patients with fibromyalgia: A nationwide population-based retrospective cohort study. PLoS One 2020; 15:e0238502. [PMID: 32881903 PMCID: PMC7470261 DOI: 10.1371/journal.pone.0238502] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2020] [Accepted: 08/10/2020] [Indexed: 11/19/2022] Open
Abstract
Objectives Our objectives are to examine whether patients with fibromyalgia (FM) present an increased risk of hearing loss (HL) compared with those without FM and to explore the relationship between comorbidities/drugs and development of HL in patients with FM. Furthermore, we investigated the incidence rate of different types of HL and the joint effects for HL with FM and comorbidities. Methods This population-based retrospective cohort study included patients with new-onset FM from 2000 to 2002 (the FM group) and age- and sex-matched randomized patients without FM (the non-FM group) from Taiwan’s National Health Insurance Research Database. Patients were followed up from baseline (3 months after FM diagnosis) until death, withdrawal, HL development, or December 31, 2013. The primary outcome was the risk of HL, which was assessed using Cox proportional-hazards analysis. Results The overall HL risk in the FM group was 1.46-fold (95% confidence interval [CI]: 1.38–1.55) higher than that in the non-FM group after adjustment for sex, age, and comorbidities (p < 0.0001). Patients with FM had significantly greater sensorineural HL (adjusted hazard ratio = 1.46, 95% CI: 1.37–1.56) than those without FM. Patients with FM having comorbidities of diabetes, hyperlipidemia, depression, and Meniere’s disease had a higher risk of HL than those without FM. Conclusion Our findings support the notion that FM influences HL and is in line with the hypothesis that the FM mechanism is related to a central nervous system abnormality in sensory processing. Health care professionals should provide appropriate screening for the risk of HL and prevention and counseling methods for patients with FM.

[PMID: 32552604 PMCID: PMC7307280 DOI: 10.1177/2331216520930545] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2019] [Revised: 04/05/2020] [Accepted: 05/01/2020] [Indexed: 11/29/2022] Open
Abstract
While listening to recorded sentences with a sound-field level of 65 dB SPL, 24 adults with hearing-aid experience used the "Goldilocks" explore-and-select procedure to adjust level and spectrum of amplified speech to preference. All participants started adjustment from the same generic response. Amplification was provided by a custom-built Master Hearing Aid with online processing of microphone input. Primary goals were to assess the effects of including a formal speech-perception test between repeated self-adjustments and of adding multitalker babble (signal-to-noise ratio +6 dB) during self-adjustment. The speech test did not affect group-mean self-adjusted output, which was close to the National Acoustics Laboratories' prescription for Non-Linear hearing aids. Individuals, however, showed a wide range of deviations from this prescription. Extreme deviations at the first self-adjustment fell by a small but significant amount at the second. The multitalker babble had negligible effect on group-mean self-selected output but did have predictable effects on word recognition in sentences and on participants' opinion regarding the most important subjective criterion guiding self-adjustment. Phoneme recognition in monosyllabic words was better with the generic starting response than without amplification and improved further after self-adjustment. The findings continue to support the efficacy of hearing aid self-fitting, at least for level and spectrum. They do not support the need for inclusion of a formal speech-perception test, but they do support the value of completing more than one self-adjustment. Group-mean data did not indicate a need for threshold-based prescription as a starting point for self-adjustment.

[PMID: 31486068 DOI: 10.1111/jgs.16109] [Citation(s) in RCA: 68] [Impact Index Per Article: 13.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2019] [Revised: 07/03/2019] [Accepted: 07/08/2019] [Indexed: 01/02/2023]
Abstract
OBJECTIVE To examine the association between hearing aids (HAs) and time to diagnosis of Alzheimer disease (AD) or dementia, anxiety or depression, and injurious falls among adults, aged 66 years and older, within 3 years of hearing loss (HL) diagnosis. DESIGN Retrospective cohort study. SETTING We used 2008 to 2016 national longitudinal claims data (based on office visit, inpatient, or outpatient healthcare encounters) from a large private payer. We used Kaplan-Meier curves to examine unadjusted disease-free survival and crude and adjusted Cox regression models to examine associations between HAs and time to diagnosis of three age-related/HL-associated conditions within 3 years of HL diagnosis. All models were adjusted for age, sex, race/ethnicity, census divisions, and prior diagnosis of cardiovascular conditions, hypertension, hypercholesterolemia, obesity, and diabetes. PARTICIPANTS The participants included 114 862 adults, aged 66 years and older, diagnosed with HL. MEASUREMENT Diagnosis of (1) AD or dementia; (2) depression or anxiety; and (3) injurious falls. INTERVENTION Use of HAs. RESULTS Large sex and racial/ethnic differences exist in HA use. Approximately 11.3% of women vs 13.3% of men used HAs (95% confidence interval [CI] difference = -0.024 to -0.016). Approximately 13.6% of whites (95% CI = 0.13-0.14) vs 9.8% of blacks (95% CI = 0.09-0.11) and 6.5% of Hispanics (95% CI = 0.06-0.07) used HAs. The risk-adjusted hazard ratios of being diagnosed with AD/dementia, anxiety/depression, and injurious falls within 3 years after HL diagnosis, for those who used HAs vs those who did not, were 0.82 (95% CI = 0.76-0.89), 0.89 (95% CI = 0.86-0.93), and 0.87 (95% CI = 0.80-0.95), respectively. CONCLUSIONS Use of HAs is associated with delayed diagnosis of AD, dementia, depression, anxiety, and injurious falls among older adults with HL. Although we have shown an association between use of HAs and reduced risk of physical and mental decline, randomized trials are needed to determine whether, and to what extent, the relationship is causal.

Abstract
Purpose Older adults seeking audiologic rehabilitation often present with medical comorbidities, yet these realities of practice are poorly understood. Study aims were to examine (a) the frequency of identification of selected comorbidities in clients of a geriatric audiology clinic, (b) the influence of comorbidities on audiology practice, and (c) the effect of comorbidities on rehabilitation outcomes. Method The records of 135 clients ( M age = 86 years) were examined. Information about comorbidities came from audiology charts (physical paper files) and hospital electronic health records (EHRs). Data about rehabilitation recommendations and outcomes came from the charts. Focus groups with audiologists probed their views of how comorbidities influenced their practice. Results The frequency of identification was 68% for visual, 50% for cognitive, and 42% for manual dexterity issues; 84% had more than one comorbidity. Also noted were hypertension (43%), falls (33%), diabetes (13%), and depression (16%). Integrating information from the audiology chart and EHR provided a more complete understanding of comorbidities. Information about hearing in the EHR included logs of outpatient audiology visits (75% of 135 cases), audiologists' care notes for inpatients and long-term care residents (25%), and entries by other health professionals (60%). Modifications to audiology practice were common and varied depending on comorbidity. High rates of success were achieved regardless of comorbidities. Conclusions In this clinic, successful outcomes were achieved by modifying audiology practice for clients with comorbidities. Increased interprofessional communication among clinicians in the circle of care could improve care planning and outcomes for older adults with hearing loss.

Abstract
ObjectiveTo evaluate the association between hearing and postural balance.Study DesignRetrospective cross-sectional study.SettingTertiary care otolaryngology clinic.Subjects and MethodsPatients examined for suspected vestibular disorder were included in this study. The outcome variable was postural sway measured by static posturography during quiet standing with eyes closed. The predictor variable was pure-tone average hearing threshold on the best hearing ear at 0.5, 1, 2, and 3 kHz. Covariates were age, sex, and vestibular disease or vestibular asymmetry assessed by bithermal caloric irrigation.ResultsIn total, 1075 patients were included. Increased hearing threshold was a strong predictor of increased postural sway (path length) after correcting for age and sex. A 10-dB increase in hearing loss on the best hearing ear predicted a mean 6.0% increase in path length (confidence interval, 2.9%-9.3%, P < .001). Of the covariates, increasing age ( P < .001) and male sex ( P = .009) were significant predictors of increased postural sway. The effect of increased hearing threshold was also significant after adjusting for vestibular disease.ConclusionIncreased hearing threshold was an independent predictor of increased postural instability, and this effect was strongest for the best hearing ear. Unilateral vestibular disease did not seem to explain this association between hearing and postural balance. Reduced hearing is associated with impaired balance, and interventions to prevent falls should be considered for patients at risk.

Abstract
OBJECTIVE We sought to identify multidimensional factors associated with health-related quality of life (HRQoL) for use in developing an inventory in which HRQoL is a core concept in evaluating the impact of hearing loss and the efficacy of rehabilitative interventions. METHOD A qualitative approach was used in which we posed two major questions to a focus group consisting of eight adults with self-reported, bilateral sensorineural hearing loss of varying degrees. In essence, those questions were: (1) How do you define quality of life?, and (2) Can you describe specific incidents in your everyday life in which your hearing loss has impacted your quality of life? The discussion was embedded within a framework that utilized a modification of the Critical Incident Technique (CIT). We used well-established analytic techniques to translate the data into unitized thought units, which we coded into meaningful categories. Response frequency was used to determine the salience of responses in addressing the research questions. RESULTS Participants defined QoL in terms of a number of primary dimensions, most of which were directly or indirectly associated with specific recalled incidents in which those dimensions have played a notable role in contributing to their QoL. CONCLUSIONS The use of well-established methods to gather and analyze qualitative data generated by self-report techniques offers a promising direction for developing a standardized inventory for identifying the factors that impact QoL for persons with hearing loss and for evaluating the success of intervention strategies aimed at improving their HRQoL.

Blood Pressure Variability Is Associated with Hearing and Hearing Loss: A Population-Based Study in Males. Int J Hypertens 2019; 2019:9891025.

Abstract
Blood pressure (BP) has been well documented to be associated with hearing loss previously. However, the role of blood pressure variability (BPV, representing BP fluctuation over a time period) on hearing remains unknown. We aimed to evaluate the relationship between BPV and hearing in Chinese population. We included 8646 male subjects from a population-based study (the Kailuan study). BP was measured every two years at routine physical examinations from 2006 to 2015. Based on five annual BP measurements, BPV was estimated by standard deviation of BP (SD), coefficient of the variation of BP (CV), and variation independent of mean of BP (VIM). Hearing was estimated by pure-tone average threshold (PTA) at low, intermediate, and high frequencies in the year of 2014. Regression models were used to evaluate the relationship between BPV and hearing. The results showed that PTAs and percentages of hearing loss at low, intermediate, and high frequencies grew gradually with increasing systolic SD (SSD) (p<0.05). After adjusting for multiple covariates, multivariate regression analyses demonstrated that variations of SBP (SSD, SCV, and VIMSBP) were all positively correlated with PTA at intermediate and high frequencies (p<0.05). Each SD increase in SSD, SCV, and VIMSBP was also positively associated with hearing loss at intermediate and high frequencies. No significant correlation was observed between variations of DBP and hearing. These findings suggest that increase in long-term BPV is associated with hearing and hearing loss. Trial registration number: Kailuan study (ChiCTRTNC-11001489).
