Prospective effects of hearing status on loneliness and depression in older persons: Identification of subgroups

Abstract Objective: To determine the possible longitudinal relationships between hearing status and depression, and hearing status and loneliness in the older population. Design: Multiple linear regression analyses were used to assess the associations between baseline hearing and 4-year follow-up of depression, social loneliness, and emotional loneliness. Hearing was measured both by self-report and a speech-in-noise test. Each model was corrected for age, gender, hearing aid use, baseline wellbeing, and relevant confounders. Subgroup effects were tested using interaction terms. Study sample: We used data from two waves of the Longitudinal Aging Study Amsterdam (2001–02 and 2005–06, ages 63–93). Sample sizes were 996 (self-report (SR) analyses) and 830 (speech-in-noise test (SNT) analyses). Results: Both hearing measures showed significant adverse associations with both loneliness measures (p < 0.05). However, stratified analyses showed that these effects were restricted to specific subgroups. For instance, effects were significant only for non-hearing aid users (SR-social loneliness model) and men (SR and SNT-emotional loneliness model). No significant effects appeared for depression. Conclusions: We found significant adverse effects of poor hearing on emotional and social loneliness for specific subgroups of older persons. Future research should confirm the subgroup effects and may contribute to the development of tailored prevention and intervention programs. Sumario Objetivo: Determinar las posibles relaciones longitudinales entre la condición auditiva y la depresión, y la condici n auditiva y la soledad, en adultos mayores. Diseño: Se usaron múltiples análisis de regresión lineal para evaluar las asociaciones entre la audición basal y el seguimiento a 4 años con la depresiún, la soledad social y la soledad emocional. La audición se midió tanto por auto-reporte como por la prueba de audición en ruido. Cada modelo fue corregido por edad, g nero, uso del auxiliar auditivo, bienestar basal y elementos relevantes de confusión. El efecto de subgrupo fue evaluado usando términos de interacción. Muestra del Estudio: Usamos datos de dos etapas del Estudio Longitudinal de Envejecimiento e Amsterdam (2001-02 y 2005-06, edades 63-93). El tamaño de las muestras fue 996 (análisis de auto-reporte (SR) y 830 (análisis de la prueba de audición en ruido). Resultados: Ambas mediciones auditivas mostraron asociaciones adversas significativas con ambas medidas de soledad (p < 0.05). Sin embargo, los análisis estratificados mostraron que estos efectos eran restringidos a subgrupos específicos. Por ejemplo, los efectos fueron significativos solo para quienes no usaban auxiliar auditivo (modelo SR – soledad social) y para hombres (SR y SNT – modelo de soledad emocional). No hubo efecto significativo para la depresión. Conclusiones: Encontramos efectos adversos significativos de un audición pobre sobre la soledad emocional y social para subgrupos específicos de personas mayores. Investigaciones futuras deberán confirmar el efecto de subgrupo y podrán contribuir al desarrollo de programas de prevenci n e intervenci n a la medida.

Hearing loss in older persons: Does the rate of decline affect psychosocial health?

Objective: This study investigates whether the rate of decline in older persons’ hearing status is associated with the rate of decrease in their psychosocial health and explores moderation by baseline hearing status, health-related factors, and sociodemographic factors. Method: Multilevel analyses were applied to data of 1,178 older participants from the Longitudinal Aging Study Amsterdam (LASA), covering 3 to 7 years of follow-up. Results: Faster decrease in speech-in-noise recognition was significantly associated with more increase in loneliness for persons with a moderate baseline speech-in-noise recognition (emotional and social loneliness) and for persons who recently lost their partner (emotional loneliness). No relationship was found with depression. Discussion: The results indicate that faster hearing decline results in more increase in loneliness in specific subgroups of older persons: in persons with an already impaired hearing and in widow(er)s. Monitoring older persons’ hearing seems important and may be a relevant starting point for targeted loneliness prevention efforts.

Interventions following hearing screening in adults: A systematic descriptive review

Abstract Objective: Adult hearing screening may be a solution to the under-diagnosis and under-treatment of hearing loss in adults. Limited use and satisfaction with hearing aids indicate that consideration of alternative interventions following hearing screening may be needed. The primary aim of this study is to provide an overview of all intervention types that have been offered to adult (≥ 18 years) screen-failures. Design: Systematic literature review. Articles were identified through systematic searches in PubMed, EMBASE, Cinahl, the Cochrane Library, private libraries, and through reference checking. Results: Of the initial 3027 papers obtained from the searches, a total of 37 were found to be eligible. The great majority of the screening programmes (i.e. 26) referred screen-failures to a hearing specialist without further rehabilitation being specified. Most of the others (i.e. seven) led to the provision of hearing aids. Four studies offered alternative interventions comprising communication programme elements (e.g. speechreading, hearing tactics) or advice on environmental aids. Conclusions: Interventions following hearing screening generally comprised referral to a hearing specialist or hearing aid rehabilitation. Some programmes offered alternative rehabilitation options. These may be valuable as an addition to or replacement of hearing aid rehabilitation. It is recommended that this be addressed in future research. Sumario Objetivo: El tamiz auditivo en adultos puede ser una solución al diagnóstico y tratamiento insuficiente de las alteraciones auditivas en adultos. El uso y satisfacción limitados con los auxiliares auditivos indica que pueden necesitarse intervenciones alternativas luego del tamiz auditivo. El propósito primario de este estudios es echar un vistazo a todos los tipos de intervención que han sido ofrecidas a adultos (≥ 18 años) que fallan dicho tamiz. Diseño: Revisión sistemática de la literatura. Se identificaron artículos a través de una búsqueda sistemática en PubMed, EMBASE, Cinahl, la Biblioteca Cochran, bibliotecas privadas y a través de revisión de referencias. Resultados: De los 3027 trabajos iniciales obtenidos de las búsquedas, se encontró un total de 37 que eran elegibles. La gran mayoría de los programas de tamiz auditivo (p.e., 26) refirieron los fallos del tamiz a un especialista en audición, sin especificar nada adicional sobre rehabilitación. La mayoría de los otros (p.e., 7) llevaron a la adaptación de auxiliares auditivos. Cuatro estudios ofrecieron intervenciones alternativas que involucraban programas de comunicación (p.e., lectura labio-facial, tácticas para escuchar) o consejo sobre ayudas ambientales. Conclusiones: Las intervenciones que siguez al tamiz auditivo involucraron referencia a especialistas en audición o rehabilitación con auxiliares auditivos. Algunos programas ofrecieron opciones alternativas de rehabilitación. Estos pueden ser valiosos como una adición o en reemplazo de la rehabilitación con auxiliares auditivos. Se recomienda que esto sea analizado en investigaciones futuras.

Decline in older persons' ability to recognize speech in noise: the influence of demographic, health-related, environmental, and cognitive factors.

Objectives: The first aim was to investigate whether the rate of decline in older persons’ ability to recognize speech in noise over time differs across age and gender. The second aim was to determine extent demographic, health-related, environmental, and cognitive factors influence the change in speech-in-noise recognition over time. Design: Data covering 3 to 7 years of follow-up (mean: 4.9 years) of a large sample of the Longitudinal Aging Study Amsterdam were used (n = 1298; 3025 observations; baseline ages: 57 to 93 years). Hearing ability was measured by a digit triplet speech-in-noise test (SNT) yielding a speech reception threshold in noise (SRTn). Multilevel analyses were used to model the change in SRTn over time. First, interaction terms were used to test differences in rate of decline across subgroups. Second, for each of the following factors the authors determined the influence on the change in SRTn: age, gender, educational level, cardiovascular conditions, information processing speed, fluid intelligence, global cognitive functioning, smoking, and alcohol use. This was done by calculating the percentage change in Btime after adding the particular factor to the model. Results: On average, respondents’ SRTn increased (i.e., deteriorated) significantly over time by 0.18 dB signal-to-noise ratio per annum. Rates were accelerated for older ages (Btime = 0.13, 0.14, 0.25, 0.27 for persons who were 57 to 65, 65 to 75, 75 to 85, and 85 to 93 years of age, respectively). Only information processing speed relevantly influenced the change in SRTn over time (17% decrease in Btime). Conclusions: Decline in older persons’ speech-in-noise recognition over time accelerated for older ages. Decline in information processing speed explained a moderate proportion of the SRTn decline. This indicates the relevance of declining cognitive abilities in the ability of older persons to recognize speech in noisy environments.

The ICF core sets for hearing loss project : functioning and disability from the patient perspective

Abstract Objective: To explore areas of functioning, disability, and environmental factors of adults with hearing loss (HL) by using the ICF classification as a tool to determine and document each element. Design: A qualitative study applying mainly focus-group methodology was applied. Study sample: Thirty-six Dutch and South African adults (≥ 18 years of age) with HL (20–95 dB HL) who used oral communication as first communication. Summative content analysis was performed on the transcripts by linkage to appropriate ICF categories. Results: 143 ICF categories were identified, most of which belonged to the Activities & Participation (d) component, closely followed by the Environmental factors component. Participants specifically mentioned categories related to oral communication and interaction. Assistive technology (such as hearing aids), noise, and support by and attitudes of others in the environment of the participants were considered highly influential for functioning and disability. Conclusions: The present study illustrates the complex and encompassing nature of aspects involved in functioning and disability of adults with HL. Findings highlight the necessity of using a multidimensional tool, such as the ICF, to map functioning and disability with hearing loss, allowing consideration and evaluation of aspects that are both internal and external.

Adult hearing screening: the Cyprus Pilot Program

Hearing loss is the third most common condition affecting adults over 65 (Cruickshanks et al., 1998). It can affect quality of life, limiting the ability to communicate efficiently, and leading to isolation, psychological strain, and functional decline (LaForge, Spector, Sternberg, 1992; Yueh, Shapiro, MacLean, Shekelle, 2003). Communication limitations impinge on the person directly, as well as the family, friends, and social circle. Reports on hearing loss among adults indicate that less than 25% of people who can benefit from amplification are actually using hearing aids, and that people diagnosed with a hearing loss delay seeking amplification by about seven years (Kochkin, 1997). Often, family members are the driving force behind a person with a hearing loss who decides to seek help. Adult hearing screening programs might have a positive effect on raising public awareness on hearing loss and its implications, and shortening delay time for intervention. There is no routine hearing screening for the adult population in Cyprus. The health system provides hearing tests for beneficiaries upon physician recommendation or self-referral. The Cyprus pilot adult hearing screening program (ΑΠΑΣ- EVERYONE- Greek acronym for Screening- Intervention-Hearing-Participation to Life) screened hearing in retired adults.

Predictors of Entering a Hearing Aid Evaluation Period: A Prospective Study in Older Hearing-Help Seekers:

This study aimed to determine the predictors of entering a hearing aid evaluation period (HAEP) using a prospective design drawing on the health belief model and the transtheoretical model. In total, 377 older persons who presented with hearing problems to an Ear, Nose, and Throat specialist (n = 110) or a hearing aid dispenser (n = 267) filled in a baseline questionnaire. After 4 months, it was determined via a telephone interview whether or not participants had decided to enter a HAEP. Multivariable logistic regression analyses were applied to determine which baseline variables predicted HAEP status. A priori, candidate predictors were divided into ‘likely’ and ‘novel’ predictors based on the literature. The following variables turned out to be significant predictors: more expected hearing aid benefits, greater social pressure, and greater self-reported hearing disability. In addition, greater hearing loss severity and stigma were predictors in women but not in men. Of note, the predictive effect of self-reported hearing disability was modified by readiness such that with higher readiness, the positive predictive effect became stronger. None of the ‘novel’ predictors added significant predictive value. The results support the notion that predictors of hearing aid uptake are also predictive of entering a HAEP. This study shows that some of these predictors appear to be gender specific or are dependent on a person’s readiness for change. After assuring the external validity of the predictors, an important next step would be to develop prediction rules for use in clinical practice, so that older persons’ hearing help-seeking journey can be facilitated.

Overlap and Nonoverlap Between the ICF Core Sets for Hearing Loss and Otology and Audiology Intake Documentation.

Objectives: The International Classification of Functioning Disability and Health (ICF) Core Sets for Hearing Loss (HL) were developed to serve as a standard for the assessment and reporting of the functioning and health of patients with HL. The aim of the present study was to compare the content of the intake documentation currently used in secondary and tertiary hearing care settings in the Netherlands with the content of the ICF Core Sets for HL. Research questions were (1) to what extent are the ICF Core Sets for HL represented in the Dutch Otology and Audiology intake documentation? (2) are there any extra ICF categories expressed in the intake documentation that are currently not part of the ICF Core Sets for HL, or constructs expressed that are not part of the ICF? Design: Multicenter patient record study including 176 adult patients from two secondary, and two tertiary hearing care settings. The intake documentation was selected from anonymized patient records. The content was linked to the appropriate ICF category from the whole ICF classification using established linking rules. The extent to which the ICF Core Sets for HL were represented in the intake documentation was determined by assessing the overlap between the ICF categories in the Core Sets and the list of unique ICF categories extracted from the intake documentation. Any extra constructs that were expressed in the intake documentation but are not part of the Core Sets were described as well, differentiating between ICF categories that are not part of the Core Sets and constructs that are not part of the ICF classification. Results: In total, otology and audiology intake documentation represented 24 of the 27 Brief ICF Core Set categories (i.e., 89%), and 60 of the 117 Comprehensive ICF Core Set categories (i.e., 51%). Various ICF Core Sets categories were not represented, including higher mental functions (Body Functions), civic life aspects (Activities and Participation), and support and attitudes of family (Environmental Factors). One extra ICF category emerged from the intake documentation that is currently not included in the Core Sets: sleep functions. Various Personal Factors emerged from the intake documentation that are currently not defined in the ICF classification. Conclusions: The results showed substantial overlap between the ICF Core Sets for HL and the intake documentation of otology and audiology, but also revealed areas of nonoverlap. These findings contribute to the evaluation of the content validity of the Core Sets. The overlap can be viewed as supportive of the Core Sets’ content validity. The nonoverlap in Core Sets categories indicates that current Dutch intake procedures may not cover all aspects relevant to patients with ear/hearing problems. The identification of extra constructs suggests that the Core Sets may not include all areas of functioning that are relevant to Dutch Otology and Audiology patients. Consideration of incorporating both aspects into future intake practice deserves attention. Operationalization of the ICF Core Sets categories, including the extra constructs identified in this study, into a practical and integral intake instrument seems an important next step.
