Relationship between self-reported hearing and vision problems, cognitive decline, depressive symptoms, and life satisfaction in older adults: a retrospective observational study.

BACKGROUND: Sensory impairment in older adults is associated with cognitive decline, elevated depressive symptoms, and low levels of life satisfaction. However, these relationships are usually investigated separately and in pairs. This study examined these relationships comprehensively, for the first time. METHODS: The analysis included 5,658 community-dwelling older adults from the China Health and Retirement Longitudinal Study (aged 50 to 108 years, 52.1% male) who completed the Jorm Informant Questionnaire Cognitive Decline in the Elderly and the Center for Epidemiological Studies-Depression-short form. A questionnaire was used to collect information on hearing, visual status, and life satisfaction. Structural equation modelling was used to examine the direct and indirect relationships between these variables. RESULTS: Self-reported hearing and vision problems are directly associated with cognitive decline and elevated depressive symptoms. In addition, hearing and vision problems are indirectly related to cognitive decline through elevated depressive symptoms. Although hearing and vision problems had no direct effect on life satisfaction, they were indirectly associated with life satisfaction through cognitive decline and depressive symptoms. CONCLUSIONS: This study provides the first epidemiological evidence of the comprehensive relationships between hearing and vision problems, cognitive decline, depressive symptoms, and life satisfaction. When older adults report hearing and/or vision problems, clinicians and caregivers should be aware of the concurrence of declined cognition, elevated depressive symptoms, and compensated life satisfaction. Future studies should examine the causal relationships and potential mechanisms of these relationships.

[Evaluation of a Screening Program: Challenges of Data Collection Using the Example of the Newborn Hearing Screening]. / Evaluation eines Screening-Programms: Herausforderungen der Datenerhebung am Beispiel des Neugeborenen-Hörscreenings.

BACKGROUND: The aim of the newborn hearing screening (NHS) is to identify and treat children with bilateral hearing disorders early. The NHS is regulated in Germany by the Pediatric Directive, which recommends an evaluation after 5 years. This evaluation was performed for the first time nationwide for children born between 2011 and 2012 regarding structural, process and result quality. OBJECTIVES: Challenges in the collection of appropriate data as basis for evaluation are described and possible improvements are suggested. METHODS: All maternity and neonatology wards performing the NHS were identified and their documentations of the NHS analysed. In addition, all pediatric audiologists were identified to gather data on children with bilateral permanent congenital hearing disorder. RESULTS: The identification of relevant maternity and neonatology wards was very burdensome. More than half of them were not aware that NHS had to be documented. There was no documentation on more than 15% of the children that were to be screened. Furthermore, data concerning bilateral congenital hearing disorders was only accessible for 60% of the expected number of affected children. CONCLUSIONS: Data required for the evaluation of the NHS regarding structural, process and result quality were incomplete and missing. The database for evaluations should be defined precisely and structures needed to obtain meaningful results have to be established in advance. Nevertheless, the evaluation of the NHS provides meaningful results concerning the screening process in Germany.

The Prevalence and Severity of Misophonia in a UK Undergraduate Medical Student Population and Validation of the Amsterdam Misophonia Scale.

Misophonia is a condition of abnormal emotional responses to specific auditory stimuli. There is limited information available on the prevalence of this condition. This study aimed to estimate the prevalence of misophonia in an undergraduate medical student population at the University of Nottingham. A secondary aim of this study was to assess the psychometric validity of the Amsterdam Misophonia Scale (A-Miso-S) questionnaire tool in this population. The A-Miso-S was administered online to medical students at the University of Nottingham. To assess the validity of the A-Miso-S, a factor analysis was conducted. To determine prevalence and severity the results of the questionnaire were quantitatively analysed using SPSS. Actor analysis was conducted. Free text responses to one questionnaire item were analysed using a thematic approach. Responses were obtained from 336 individuals. Clinically significant misophonic symptoms appear to be common, effecting 49.1% of the sample population. This is statistically significantly higher prevalence than previous studies have found (p < 0.00001). Using the classification of the A-Miso-S, mild symptoms were seen in 37%, moderate in 12%, severe in 0.3% of participants. No extreme cases were seen. The A-Miso-S was found to be a uni-factorial tool, with good internal consistency. This study has provided new information on misophonia and validity of the A-Miso-S questionnaire in a sample population of UK undergraduate medical students. The results indicate that misophonia is a phenomenon that a significant proportion of medical students experience though only a small subset experience it severely.

Exploring perceptions, barriers, and enablers for delivery of primary ear and hearing care by community health workers: a photovoice study in Mukono District, Uganda.

BACKGROUND: Hearing loss is a prevalent but neglected disease, especially in low- or middle-income countries. The role of Community Health Workers (CHWs) to deliver primary ear and hearing care has been explored in several studies from a technical standpoint, but understanding perceptions, barriers, and enablers of such an approach from the perspective of CHWs themselves through a health equity lens has been less well documented. METHODS: This qualitative study used photovoice to explore the views and experiences of CHWs in the Seeta Nazigo Parish of Mukono District in the delivery of ear and hearing care in the community. CHWs were trained in ear and hearing care, and provided with digital cameras to capture photographs related to their work in the community over the following 3 months. Individual interviews regarding the photographs were held at the end of each month, in addition to one focus group discussion. A community workshop was convened at the end of the study to display the photos. Thematic analysis of photographs was conducted using Braune and Clarkes six-step framework. We also used the data to explore potential roles for key stakeholders in primary ear and hearing care, and how photovoice may facilitate their engagement. RESULTS: 13 CHWs participated in the study. Several themes were generated from analysis. CHWs perceived a high burden of ear and hearing disorders in their community and recognised the role they could play in tackling that burden. Potential barriers identified included a lack of equipment, training, and supervision of CHWs; logistical, financial, or psychological barriers to community participation; and the widespread use of traditional medicine. CHWs identified roles for the government and NGO bodies to enable and support delivery of ear and hearing care in the community. The community workshop was a useful method to engage key stakeholders in this topic. CONCLUSIONS: Photovoice is a powerful method to capture issues affecting CHWs. Here it was used to identify a number of perceptions, barriers and enablers to the delivery of ear and hearing care. Our results may inform future strategy in the field of ear and hearing care, and the potential use of photovoice to enact sociocultural change.

Epidemiology of cerebral palsy in Sumba Island, Indonesia.

AIM: To define the epidemiology, clinical characteristics, and rehabilitation status of children with cerebral palsy (CP) in Sumba Island, Indonesia. METHOD: A community-based key informant method survey among children (aged <18y) with CP was conducted between March and August 2017. Children with suspected CP underwent detailed neurodevelopmental assessment by a multidisciplinary medical team. Socio-demographic characteristics, aetiology, motor type, motor severity, associated impairments, educational, and rehabilitation status were documented. RESULTS: There were 130 children with clinically confirmed CP. The mean age at assessment was 8 years 11 months and 43.8% (n=57) of the children were female. The mean age at CP diagnosis was 6 years 5 months. Of these children, 46.9% (n=61) had post-neonatally acquired CP, most frequently because of vaccine-preventable infectious encephalopathy (73.8%, n=45). In total, 80.8% (n=105) had a predominantly spastic motor type of CP and 83.8% (n=109) were classified in Gross Motor Functional Classification System levels III to V. A total of 77.7% (n=101) had at least one associated impairment (speech 77.5%, intellectual 29.2%, visual 13.8%, hearing 20.0%, and epilepsy 13.5%). And 66.2% (n=86) had never received rehabilitation services. INTERPRETATION: Post-neonatally acquired CP was common in this setting. Addressing preventable post-neonatally acquired risk factors for CP should be a public health priority. Earlier identification and diagnosis of CP would also provide new opportunities for early intervention and targeted rehabilitation services.

[Audiological correlates of age-related manifestations of auditory disorders.]

The aim of the study was a comparative analysis of complaints and audiological findings in patients of the audiological center depending on their age. The results of the examination of 300 firstly consulted patients (random sample) are presented. The group of young patients (19-44 years) included 40 people; middle age (45-59 years) - 62 people; elderly (60-74 years) - 100 people; senile age (75-90 years) - 98 people. The survey included the collection of complaints and anamnesis, ENT checkup, pure tone audiometry, impedancemetry, speech audiometry in headphones to detect the signs of Central Auditory Processing Disorder or in the free sound field to assess the effectiveness of hearing aids. It was found that for early diagnosis of hearing loss and prevention of age-related sensory-cognitive dysfunction, it is advisable to use not only the results of pure tone audiometry, but also the data of speech audiometry, as well as the analysis of subjective complaints. The results of the work indicate the need for hearing screening in the population over 60 years old.

Hearing Status in Survivors of Childhood Acute Myeloid Leukemia Treated With Chemotherapy Only: A NOPHO-AML Study.

BACKGROUND: As more children survive acute myeloid leukemia (AML) it is increasingly important to assess possible late effects of the intensive treatment. Hearing loss has only sporadically been reported in survivors of childhood AML. We assessed hearing status in survivors of childhood AML treated with chemotherapy alone according to 3 consecutive NOPHO-AML trials. PROCEDURE: A population-based cohort of children treated according to the NOPHO-AML-84, NOPHO-AML-88, and NOPHO-AML-93 trials included 137 eligible survivors among whom 101 (74%) completed a questionnaire and 99 (72%) had otologic and audiologic examination performed including otoscopy (72%), pure tone audiometry (70%), and tympanometry (60%). Eighty-four of 93 (90%) eligible sibling controls completed a similar questionnaire. RESULTS: At a median of 11 years (range, 4 to 25) after diagnosis, hearing disorders were rare in survivors of childhood AML and in sibling controls, with no significant differences. None had severe or profound hearing loss diagnosed at audiometry. Audiometry detected a subclinical hearing loss ranging from slight to moderate in 19% of the survivors, 5% had low-frequency hearing loss, and 17% had high-frequency hearing loss. CONCLUSIONS: The frequency of hearing disorders was low, and hearing thresholds in survivors of childhood AML were similar to background populations of comparable age.

Working in preschool increases the risk of hearing-related symptoms: a cohort study among Swedish women.

PURPOSE: To assess whether working in preschools increases the risk of hearing-related symptoms and whether age, occupational noise, and stressful working conditions affect the risk. METHODS: Questionnaire data on hearing-related symptoms were analysed in women aged 24-65 (4718 preschool teachers, and 4122 randomly selected general population controls). Prevalence and risk ratio (RR) of self-reported hearing loss, tinnitus, difficulty perceiving speech, hyperacusis and sound-induced auditory fatigue were assessed by comparing the cohorts in relation to age and self-reported occupational noise and stressful working conditions (effort-reward imbalance and emotional demands). RR was calculated using log-binomial regression models adjusted for age, education, income, smoking, hearing protection, and leisure noise. Incidence rates and incidence rate ratios (IRR) were calculated for retrospectively reported onset of all symptoms except sound-induced auditory fatigue. RESULTS: Compared to the controls, preschool teachers had overall more than twofold RR of sound-induced auditory fatigue (RR 2.4, 95% confidence interval 2.2-2.5) and hyperacusis (RR 2.3, 2.1-2.5) and almost twofold for difficulty perceiving speech (RR 1.9, 1.7-2.0). Preschool teachers had a threefold IRR of hyperacusis (IRR 3.1, 2.8-3.4) and twofold for difficulty perceiving speech (IRR 2.4, 2.2-2.6). Significantly although slightly less increased RR and IRR were observed for hearing loss and tinnitus. RR and IRR were generally still increased for preschool teachers when stratified by age and occupational exposure to noise and stress. CONCLUSIONS: This large cohort study showed that working as preschool teacher increases the risk of self-reported hearing-related symptoms, indicating a need of preventative measures.

Hearing and ear status of Pacific children aged 11 years living in New Zealand: the Pacific Islands families hearing study.

OBJECTIVE: This study aimed to determine the prevalence of hearing loss and ear problems in Pacific children, and investigate current and past demographic, health and social factors potentially associated with hearing and ear problems. DESIGN: A cross-sectional observational study design nested within a birth cohort was employed. STUDY SAMPLE: Nine-hundred-twenty Pacific children aged 11 years were audiologically assessed. Using average hearing thresholds at 500, 1k and 2k Hz, 162 (18%) right and 197 (21%) left ears had ≥20 dB hearing loss. Hearing loss was mild (20-39 dB) in most cases; 2% of ears had moderate to moderate-severe (40-69 dB) hearing loss. However, only 101 (11%) children had normal peripheral hearing defined by passing hearing threshold, tympanogram and distortion product otoacoustic emission assessments. Those with confirmed middle ear disease at age 2 years had significantly increased odds of a non-Type A tympanogram (adjusted odds ratio: 2.00; 95% confidence interval: 1.56, 2.50) when re-assessed at age 11 years. CONCLUSIONS: Hearing loss, abnormal tympanograms, and auditory processing difficulties were present in many Pacific children. Interventions are also urgently needed to mitigate the effect of the longstanding ear disease likely to be present for many Pacific children.

Assessing Positive Child Health among Individuals Born Extremely Preterm.

OBJECTIVE: To assess the development of a Positive Child Health Index (PCHI) based on 11 adverse outcomes and evaluate the association of PCHI with quality of life (QoL) scores in a preterm cohort. STUDY DESIGN: A total of 889 children enrolled in the Extremely Low Gestational Age Newborn (ELGAN) study in 2002-2004 were followed up at 10 years of age. A parent/caregiver completed questionnaires for child QoL, asthma, visual or hearing impairment, gross motor function impairment, epilepsy, attention deficit/hyperactivity disorder, anxiety, and depression. The child was assessed for cognitive impairment, autism, and obesity. PCHI scores were computed and linear regression models were used to evaluate the relationship between QoL categories (psychosocial, physical, emotional, social, school, and total) and the PCHI (dichotomized and coded as a multilevel categorical predictor) and to assess sex differences. RESULTS: Among ELGAN children, higher PCHI scores were associated with higher reported QoL scores for all QoL categories. Children with no disorders and a PCHI of 100% had Pediatric Quality of Life Inventory total scores that were 11 points higher than children with 1 or more adverse outcomes (PCHI of <100%). Boys had lower QoL scores for the total, psychosocial, social, and school categories. CONCLUSIONS: Positive child health assessed using a quantitative PCHI was associated with QoL across the ELGAN cohort at school age. In the current study, the PCHI encompassed 11 outcomes assessed in ELGANs. Future research could include an enhanced panel of child health outcomes to support the use of PCHI as an indicator of positive child health.

Hearing Aid Acquisition in Chinese Older Adults With Hearing Loss.

OBJECTIVES: To investigate the prevalence and associated factors of hearing aid acquisition in Chinese older adults. METHODS: We obtained data from a population-based survey on ear and hearing disorders, which was conducted in 4 provinces of China in 2014 to 2015. Trained examiners conducted pure tone audiometry and audiologists further ascertained for hearing loss. We relied on hearing conditions and audiologists' recommendations to identify 1503 participants who needed to wear hearing aids. RESULTS: Among those 1503 participants, the estimated prevalence of hearing aid acquisition was 6.5% (95% confidence interval = 5.3%, 7.8%). Urban residency, having severe hearing loss, understanding hearing aid function, and receiving a hearing test in the past 12 months were associated with elevated prevalence of hearing aid acquisition. The top-3 reported reasons for not acquiring a hearing aid were not understanding its function (25.4%), not needing it (22.3%), and not being able to afford it (21.3%). CONCLUSIONS: Hearing aid use, as a widespread rehabilitation and treatment of hearing loss, remains a big challenge in China. Apart from providing low-cost hearing aids, more efforts should focus on improving hearing knowledge and disseminating information about hearing aid function among older adults.

Visual and hearing impairments are associated with cognitive decline in older people.

INTRODUCTION: highly prevalagent hearing and vision sensory impairments among older people may contribute to the risk of cognitive decline and pathological impairments including dementia.This study aims to determine whether single and dual sensory impairment (hearing and/or vision) are independently associated with cognitive decline among older adults and to describe cognitive trajectories according to their impairment pattern. MATERIAL AND METHODS: we used data from totals of 13,123, 11,417 and 21,265 respondents aged 50+ at baseline from the Health and Retirement Study (HRS), the English Longitudinal Study of Ageing (ELSA) and the Survey of Health, Ageing and Retirement in Europe (SHARE), respectively. We performed growth curve analysis to identify cognitive trajectories, and a joint model was used to deal with attrition problems in longitudinal ageing surveys. RESULTS: respondents with a single sensory impairment had lower episodic memory score than those without sensory impairment in HRS (ß = -0.15, P < 0.001), ELSA (ß = -0.14, P < 0.001) and SHARE (ß = -0.26, P < 0.001). The analysis further shows that older adults with dual sensory impairment in HRS (ß = -0.25, P < 0.001), ELSA (ß = -0.35, P < 0.001) and SHARE (ß = -0.68, P < 0.001) remembered fewer words compared with those with no sensory impairment. The stronger associations between sensory impairment and lower episodic memory levels were found in the joint model which accounted for attrition. CONCLUSIONS: hearing and/or vision impairments are a marker for the risk of cognitive decline that could inform preventative interventions to maximise cognitive health and longevity. Further studies are needed to investigate how sensory markers could inform strategies to improve cognitive ageing.

Improving early audiological intervention via newborn hearing screening in Belgium.

BACKGROUND: Newborn hearing screening programs aim to lower the ages at audiological intervention among hearing-impaired children. In Wallonia and Brussels (Belgium), audiological intervention data are not collected in the screening program, and the ages at initiating audiological care have never been assessed. This study aimed to assess the evolution in the ages at initiating audiological intervention in the context of a newborn hearing screening program implementation. METHODS: This population-based descriptive study used data from the Belgian healthcare billing database. The main outcomes were the children's ages at the initial audiological assessment, hearing-aid fitting, and cochlear implantation. Results were compared to the same outcomes from another Belgian regional program (Flanders) that was implemented one decade earlier. Annual birth cohorts from 2006 to 2011 were included in the study. RESULTS: In Wallonia-Brussels, the median ages for all outcomes tended to decrease over time but remained higher than in Flanders for each birth cohort. For all outcomes except the hearing-aid fitting, differences in median ages between the two regions became less pronounced during the study period. In 2006, < 23% of the children from Wallonia-Brussels received any audiological care before the age of 12 months and these proportions were approximately 2-fold greater in the subsequent birth cohorts. For all outcomes, early care (< 12 months) was typically delivered less frequently in Wallonia-Brussels, compared to the delivery in Flanders. These region-specific differences exhibited a decreasing trend over time, and statistically significant differences were less common in the later birth cohorts. CONCLUSIONS: We conclude that the hearing screening program in Wallonia and Brussels promoted earlier audiological intervention among hearing-impaired children. However, milestones recommended by experts for an early intervention were not totally encountered. We also recommend collecting audiological intervention data as part of this program, which can facilitate more accurate and regular program evaluation.

Prevalence and factors associated with tinnitus: data from adult residents in Guangdong province, South of China.

There is a lack of national studies on tinnitus in China and data based on a large sample size from multiple areas of the country. A cross-sectional study was carried out in Guangdong province from October 2015 to February 2016. In the study, tinnitus was defined as the presence of ringing, buzzing or other sounds in the ears in the past one year. Fourteen districts in Guangdong Province were selected as the first-level cluster by using the sampling method of probability proportional to size (PPS). Two sub-districts in each first-level cluster were randomly selected as the second-level cluster by PPS method. The sample consisted of 3705 eligible people aged over 18 years old, which were also selected by the PPS methods. The prevalence of tinnitus was 10.4% in Guangdong Province. Age, region, educational background, hearing impairment, ear trauma, otitis media and self-health report were the main risk factors for tinnitus. Tinnitus is a common condition and a large population suffers from tinnitus in Guangdong province, south of China. Greater public awareness and understanding of the associated factors are required for further interventions of prevention and management of tinnitus in China.

Bidirectional associations between psychological distress and hearing problems: an 18-year longitudinal analysis of the British Household Panel Survey.

OBJECTIVE: Hearing problems are a significant public health concern. It has been suggested that psychological distress may represent both a cause and a consequence of hearing problems. Prospective data that allow testing such potential bi-directionality have thus far been lacking. The present study aimed to address this knowledge gap. Random (RE) and fixed effects (FE) panel regression models estimated the association of psychological distress (GHQ-12) and participant-reported hearing problems. Data from 18 annual waves of the British Household Panel Survey were used (n = 10,008). Psychological distress was prospectively associated with self-reported hearing problems in women (multivariable odds ratios (ORs) ≥1.44; one-year time lag ≥ 1.16) and men (ORs ≥ 1.15; time lag ≥ 1.17). Conversely, self-reported hearing problems were associated with increases in psychological distress in both sexes (OR ≥ 1.26; time lag ≥ 1.08). These associations were independent of the analytical strategy and of adjustment for sociodemographic variables, lifestyle factors, and measurement period. We present first evidence of a bidirectional association between psychological distress and self-reported hearing problems. These findings suggest that stress management interventions may contribute to the prevention of self-reported hearing problems, and, in turn, alleviating self-reported hearing problems may reduce psychological distress.

Hearing loss and work participation: a cross-sectional study in Norway.

OBJECTIVE: To study work participation of persons with hearing loss, and associations with hearing disabilities, self-reported workability, fatigue and work accommodation. DESIGN: Cross-sectional internet-based survey. STUDY SAMPLE: A total of 10,679 persons with hearing loss within working-age were invited to answer the survey, where 3330 answered (35.6%). RESULTS: Degree of hearing loss was associated with low workability, fatigue and work place accommodation, while sick leave was associated with fatigue. Degree of hearing loss was positively associated with being unemployed (p < .001) and having part-time work (p < .01) (often combined with disability benefits) for women. Work place accommodation was more frequently provided among respondents working with sedentary postures, high seniority, long-term sick leave or low workability. Additional unfavourable sensory conditions were associated with decreased employment (p < .001) and workability, and an increase in sick leave (p < .01) and fatigue (p < .001). CONCLUSIONS: Hearing loss seemed to influence work participation factors negatively; particularly, for moderate hearing loss and for women, even though the degree of employment was high. A lack of work place accommodation when there was a need for such was found. This implies increased attentiveness towards individual needs concerning the experienced disability a hearing loss may produce. A more frequent use of hearing disability assessment is suggested.

A Large-Scale Study of Misophonia.

OBJECTIVE: We aim to elucidate misophonia, a condition in which particular sounds elicit disproportionally strong aversive reactions. METHOD: A large online study extensively surveyed personal, developmental, and clinical characteristics of over 300 misophonics. RESULTS: Most participants indicated that their symptoms started in childhood or early teenage years. Severity of misophonic responses increases over time. One third of participants reported having family members with similar symptoms. Half of our participants reported no comorbid clinical conditions, and the other half reported a variety of conditions. Only posttraumatic stress disorder (PTSD) was related to the severity of the misophonic symptoms. Remarkably, half of the participants reported experiencing euphoric, relaxing, and tingling sensations with particular sounds or sights, a relatively unfamiliar phenomenon called autonomous sensory meridian response (ASMR). CONCLUSION: It is unlikely that another "real" underlying clinical, psychiatric, or psychological disorder can explain away the misophonia. The possible relationship with PTSD and ASMR warrants further investigation.

[Musculoskeletal, hearing and skin problems related to playing the instrument]. / Dolegliwosci miesniowo-szkieletowe, sluchowe i skórne zwiazane z gra na instrumencie.

BACKGROUND: Physical demands, exposure to noise and intense contact of skin with musical instruments - inevitable in musicians' job - influence the development of musculoskeletal, hearing and skin problems. This paper aims at identifying playing-related health problems among Polish musicians and potential differences in this regard between students and professional musicians. MATERIAL AND METHODS: This questionnaire study involved 255 musicians who volunteered to participate - 104 students and 151 professional musicians having music education. The study sample included 61% of women. Mean age of the participants equaled 31 years old, mean playing experience - 23 years old. RESULTS: From 10% to 79% (depending on the affected body part) of the studied musicians experienced musculoskeletal problems. Hearing (41% - tinnitus; 43% - hearing impairment and 52% - hyperacusis) and skin problems (69% - callosities, 58% - abrasions and 26% - allergic reactions) were reported less frequently and were assessed as less severe than musculoskeletal symptoms. The studied professionals assessed their hearing problems (hyperacusis, hearing impairment and tinnitus) as significantly more severe than reported by students. Young musicians, in turn, experienced more severe abrasions than the studied professional musicians. We found no significant differences between students and professionals as regards their musculoskeletal problems. CONCLUSIONS: Playing-related health risks translate into relatively high prevalence of musculoskeletal as well as hearing and skin problems among musicians. Hence, it is essential for future studies to search for risk factors for these health problems as well as effective corrective and therapeutic measures. Med Pr 2018;69(4):383-394.

Hearing Care Intervention for Persons with Dementia: A Pilot Study.

OBJECTIVE: Hearing loss is a commonly unmet need among adults with dementia that may exacerbate common dementia-related behavioral symptoms. Accessing traditional audiology services for hearing loss is a challenge because of high cost and time commitment. To improve accessibility and affordability of hearing treatment for persons with dementia, there is a need for unique service delivery models. The purpose of this study is to test a novel hearing intervention for persons with dementia and family caregivers delivered in outpatient settings. METHODS: The Memory-HEARS pilot study delivered a 2-hour in-person intervention in an outpatient setting. A trained interventionist provided hearing screening, communication strategies, and provision of and instruction using a simple over-the-counter amplification device. Caregivers (N = 20) responded to questionnaires related to depression, neuropsychiatric symptoms, and caregiver burden at baseline and 1-month postintervention. RESULTS: Overall, caregivers believed the intervention was beneficial, and most participants with dementia wore the amplification device daily. For the depression and neuropsychiatric outcome measures, participants with high symptom burden at baseline showed improvement at 1-month postintervention. The intervention had no effect on caregiver burden. Qualitative responses from caregivers described improved engagement for their loved ones, such as laughing more, telling more stories, asking more questions, and having more patience. CONCLUSION: The Memory-HEARS intervention is a low-cost, low-risk, nonpharmacologic approach to addressing hearing loss and behavioral symptoms in patients with dementia. Improved communication has the potential to reduce symptom burden and improve quality of life.

Dichotic Digits Test Performance Across the Ages: Results From Two Large Epidemiologic Cohort Studies.

OBJECTIVES: The Dichotic Digits test (DDT) has been widely used to assess central auditory processing but there is limited information on observed DDT performance in a general population. The purpose of the study was to determine factors related to DDT performance in a large cohort spanning the adult age range. DESIGN: The study was cross-sectional and subjects were participants in the Epidemiology of Hearing Loss Study (EHLS), a population-based investigation of age-related hearing loss, or the Beaver Dam Offspring Study (BOSS), a study of aging in the adult offspring of the EHLS members. Subjects seen during the 4th EHLS (2008 to 2010) or the 2nd BOSS (2010 to 2013) examination were included (N = 3655 participants [1391 EHLS, 2264 BOSS]; mean age = 61.1 years, range = 21 to 100 years). The free and right ear-directed recall DDTs were administered using 25 sets of triple-digit pairs with a 70 dB HL presentation level. Pure-tone audiometric testing was conducted and the pure-tone threshold average (PTA) at 0.5, 1, 2, and 4 kHz was categorized using the worse ear: no loss = PTA ≤ 25 dB HL; mild loss = 25 < PTA ≤ 40 dB HL; moderate or marked loss = PTA > 40 dB HL. Cognitive impairment was defined as a Mini-Mental State Examination score < 24 (maximum = 30) or a self- or proxy-reported history of dementia or Alzheimer's disease. Demographic information was self-reported. General linear models were fit and multiple linear regression was performed. RESULTS: The mean total free recall DDT score was 76.7% (range = 21.3 to 100%). Less than 10% of the participants had a total free recall score below 60% correct. The mean right ear-directed recall score was 98.4% with 69% of the participants scoring 100% and another 15.5% scoring 98.7% (1 incorrect digit). In multivariable modeling of the total free recall scores, the predicted mean free recall score was 1 percentage point lower for every 5-year increase in age, 2.3 percentage points lower in males than females, 8.7 percentage points lower in participants with less than a high school degree than in those with college degrees, 6.8 percentage points lower in participants with a moderate or marked hearing loss compared with no hearing loss, and 8.3 percentage points lower in participants with cognitive impairment compared with those without cognitive impairment. These 5 factors were independently and significantly related to performance and accounted for 22.7% of the total variability in free recall scores. CONCLUSIONS: Substantial variation in the total free recall DDT scores but very little variation in the right ear-directed recall DDT scores was observed. Age, sex, education, hearing loss severity, and cognitive impairment were found to be significantly related to DDT scores but explained less than 25% of the total variability in total free recall scores. The right ear-directed recall DDT by itself may not be of benefit in assessing central auditory processing in a general population because of its limited variability but further evaluation of factors potentially related to free recall DDT variability may prove useful.
