BACKGROUND: The objective of this study is to estimate the prevalence of self-reported hearing difficulties, vision difficulties and combined vision and hearing difficulties in a Swedish adult population that varies according to migration status, sex, age, disability measured by ADL and IADL and educational attainment level.

METHODS: The study utilised data from the Survey of Health, Ageing and Retirement in Europe, which consisted of 2257 individuals aged 60 and above that were interviewed in Sweden in the 2019/2020, SHARE wave 8. To determine the prevalence of sensory difficulties (hearing, vision and dual-sensory difficulties) among various subgroups of the population, a multinomial logistic regression was used. The results of these analyses are presented in terms of predicted probabilities.

RESULTS: The study findings indicate that foreign-born older adults experience a lower prevalence of visual difficulties (6.2% [3.3-11.5] in comparison to their Swedish-born counterparts. Moreover, older adults with higher levels of education tend to report a lower prevalence of sensory difficulties overall. Furthermore, sex differences are apparent, with males reporting a higher prevalence of hearing difficulties (18.9% [15.5-22.8] vs. 12.8% [10.7-15.3]) and females reporting a higher prevalence of vision difficulties (12.7% [10.7-15.1] vs. 8.5%[6.8-10.5]).

CONCLUSION: The findings highlight disparities in the prevalence and type of perceived sensory difficulties experienced by older adults, by factors such as age, sex, education and migration status. It is important to consider these demographic factors in healthcare planning and interventions aimed at mitigating sensory difficulties in the older population.

PURPOSE: There is an increasing concern regarding hazardous recreational noise exposure among adolescents and young adults. Daily exposure to loud sound levels over a long period of time can increase the risk of noise-induced hearing loss. The full extent of the impact of recreational noise on hearing is not yet fully understood. The purpose of this review was to synthesize research that investigated hearing function in relation to recreational noise exposure in adolescents and young adults.

METHOD: A systematic literature search of five databases covering the years 2000-2023 was performed. The articles included investigated audiological measurements of hearing function in relation to recreational noise exposure.

RESULTS: Four hundred sixty records were identified, of which 20 met the inclusion criteria and were included in the results. This review showed that although some recreational noise activities can be potentially harmful, there is an unclear relationship between exposure and outcome. Some findings indicated hearing threshold shifts or reduced otoacoustic emission amplitudes after recreational noise exposure, but most changes were short term and in the extended high-frequency range.

CONCLUSIONS: There seemed to be inconsistencies regarding the utilization of methods of measuring exposure and outcome between studies. This might be one reason for the differing results in studies on the reported impact on hearing function from recreational noise exposure. To draw more certain conclusions about long-term effects, there is a need for longitudinal research that utilizes sound level measurements to assess low and high degrees of recreational noise exposure in relation to hearing function.

PURPOSE: The aim of the current study was to explore the construct validity and internal consistency reliability of the International Classification of Functioning, Disability and Health (ICF)-based original English version of the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) and to revise the HFEQ based on the results.

METHOD: This study used a cross-sectional survey design. The data were collected using an online survey. Adults with self-reported hearing disability (n = 513) from the United States were included. The ICF components of body functions, activity and participation, and environmental factors were tested as the underlying structure of the HFEQ using confirmatory factor analysis and then adjusted by triangulation with previous content validation.

RESULTS: The results of the current study confirmed the ICF components of body functions, activity and participation, and environmental factors as underlying constructs of the HFEQ. However, after triangulation with previous content validation, fine adjustments were made. The revised version of the HFEQ includes two removed items and a fine-tuned factor structure.

CONCLUSION: The results confirm that the structure of the HFEQ aligns with the ICF, and the overall results indicate that HFEQ has acceptable construct validity and internal consistency.

BACKGROUND: Persons with hearing loss (HL) are a vulnerable group in working life. Studies have shown that they are more likely than the general population to be in part-time work, to be unemployed, receive disability pension, and to be on sick leave. Many workers with HL also experience unhealthy work conditions, such as jobs where they experience high demands combined with low control as well as safety concerns and social isolation. There is a lack of studies that focus on factors that promote a healthy, sustainable work situation for the target group.

OBJECTIVE: To investigate health factors that contribute to a sustainable work situation for employees with HL.

METHODS: The current study was a comparative, observational study with a cross-sectional design including a clinical population of adults with HL. Comparisons were made between workers with HL "in work" and workers with HL on "HL-related sick leave".

RESULTS: Seven health factors were identified. Those "in work" experienced a healthier work environment as well as lower levels of mental strain, hearing-related work characteristics and content, cognitively demanding work content, hearing-related symptoms, energy-demanding activities, and bodily aches and pain than those on "HL-related sick leave".

CONCLUSION: The results demonstrate a clear pattern regarding health factors for a sustainable working life. The type of job was not related to whether an individual was on sick leave or working. Rather, the work climate and the content of the work mattered.

BACKGROUND: The objective of this study is to explore the bidirectional, longitudinal associations between self-reported sensory functions (hearing/vision) and cognitive functioning among older adults in Sweden and Denmark during the period 2004-2017.

METHODS: The study is based on data from The Survey of Health, Ageing and Retirement in Europe and consists of 3164 persons aged 60 to 93 years. Within-person associations between sensory and cognitive functions were estimated using random intercept cross-lagged panel models.

RESULTS: The results indicated that cognitive and sensory functions were associated within their respective domains over time. The results on the bidirectional associations between sensory functions and cognition over time showed weak and statistically non-significant estimates.

CONCLUSION: Our study showed no clear evidence for cross-lagged effects between sensory functions and cognitive functioning. Important to note, however, is that using longitudinal data to estimate change within persons is a demanding statistical test and various factors may have contributed to the absence of conclusive evidence in our study. We discuss several of these factors.

OBJECTIVES: Self-assessment instruments are commonly used in audiological rehabilitation. However, several studies highlight the lack of multidimensionality in existing outcome measures, with the consequence that they only partially capture aspects of functioning in everyday life for people living with hearing loss. This study aimed to develop and investigate the content validity of a self-assessment instrument based on the validated Brief International Classification of Functioning, Disability, and Health Core Set for Hearing Loss.

DESIGN: The design was a two-part instrument development study. The first part focused on the item-generation process of the instrument, named the Hearing and Functioning in Everyday Life Questionnaire (HFEQ) during an experts' workshop. The second part focused on international content validation of the instrument using group interviews. Strategic sampling was used and 30 adults with hearing loss from India, South Africa, and the United States participated in the group interviews.

RESULTS: The expert's workshop resulted in the first version of the HFEQ containing 30 items. The results from group interviews show that the content of the HFEQ was considered to be valid concerning its relevance, comprehensiveness, and comprehensibility. A majority (73%) of the HFEQ items were perceived by the participants as relevant and easy to comprehend. For the remaining 27% of the items, the content was perceived to be relevant in all countries, but some terms and expressions were reported to require rewording or clearer examples. These modifications will be made in the next step of the development process.

CONCLUSION: Content validation of the HFEQ demonstrates promising results, with participants perceiving the content as relevant and comprehensible. Further psychometric validation is required to investigate other psychometric properties, such as construct validity and reliability. The HFEQ has the potential to become a valuable new instrument for assessing everyday functioning in people with hearing loss in audiological rehabilitation and in research.

A participatory-based intervention was performed in Sweden, aimed at improving the sound environment in one preschool (n = 20) and one obstetric ward (n = 50), with two controls each (n = 28, n = 66). Measured sound levels, and surveys of noise annoyance, hearing-related symptoms and emotional exhaustion were collected before, and three and nine months after the interventions, comparing intervention and control groups over time. The results of this first implementation in a limited number of workplaces showed significantly worsening of hyperacusis, sound-induced auditory fatigue, emotional exhaustion and increased sound levels in the preschool, and worsening of noise annoyance in both intervention groups. Increased risk awareness, limited implementation support and lack of psychosocial interventions may explain the worsening in outcomes, as might the worse baseline in the intervention groups. The complexity of the demands in human-service workplaces calls for further intervention studies.

Objective: The aim of the study was to explore and describe how workers in communication-intenseworkplaces in health care and preschools experience the sound environment. The depen-dence on vocal communication and social interaction poses a challenge using hearing pro-tection in these working environments.

Method: A qualitative method was used, more specifically inductive thematic analysis was used, asthis approach was deemed suitable to explore the staff’s experiences of the sound environ-ment. Data were collected by interviews and to increase trustworthiness, several researcherswere involved in the data collection and analysis.

Study sample: Workers from two preschools, one obstetrics ward and one intensive care unit took part inthe study.

Results: Four main themes emerged from the thematic analysis: A challenging and harmful soundenvironment; Health-related effects of a challenging and harmful sound environment; Agood sound environment is not prioritised; and Resourceful and motivated staff.

Conclusions: Workers in communication-intense workplaces in preschools, obstetrics care and intensivecare reported that there was a relationship between the sound environment and negativehealth effects. In addition, the results suggests that the high motivation for change amongstaff should be utilised together with an increased prioritization from the management toreach innovative context specific improvements to the sound environment in communicationintense working environments.

OBJECTIVES: Improvements in educational attainment, cognitive and sensory functions, and a decline in the prevalence of disabilities have been observed in older adults in Sweden and Denmark. In the present study, it was investigated whether better cognition, higher educational attainment, and improved sensory function among older adults aged 60 and older in these countries have contributed to decreasing rates of old-age disabilities.

METHODS: The analyses were based on repeated cross-sectional data from the Survey of Health, Ageing, and Retirement in Europe, for 2004-2017 period. Descriptive data was used to benchmark the declining prevalence of disabilities, improving cognitive and sensory function, and increased educational level. The association between time and disabilities was analyzed with logistic regression models and the contribution of the improved cognitive, education and sensory function to the declining prevalence of old-age disabilities was estimated using the Karlson-Holm-Breen (KHB) method for mediation analysis.

RESULTS: The analysis suggests that the declining prevalence of old-age disabilities in Sweden and Denmark between 2004 and 2017, can largely be attributed to improved cognitive function and vision, and to a lesser extent by education and hearing ability.

DISCUSSION: These findings raise important questions about the causal mechanisms producing the associations between cognition, education, and sensory functions and disability in older age. Future studies should explore the causal nature of the associations between these mediators, and old-age disabilities. In addition, they should explore whether these findings differ across regional and cultural contexts and over different time periods.
