Differences Between Self-Reported and Objectively Measured Hearing Loss at Age 61-63 Years: The Newcastle Thousand Families Birth Cohort

Virtual Staff Training to Support Communication for Older Adults With Untreated Hearing Loss in Care Settings

PURPOSE

The current quasi-experimental study aimed to develop and evaluate a virtual staff training on age-related hearing loss at a care organization for older adults.

METHOD

Training included the use of affordable headset amplifiers and a hands-on activity in which hearing loss was simulated. Staff were encouraged to offer amplifiers to assist in communication given the high prevalence of untreated hearing loss among older adults and the increased communication difficulty that results from mask-wearing.

RESULTS

Quantitative results (N = 51) from the pre/post questionnaire suggest that staff members gained knowledge about hearing loss and communication through the training session. Qualitative data over the 6-month post training suggest that some older adults had not only improved speech understanding but also improved quality of interactions with staff. The main reasons for not using the amplifiers were that staff would forget they had access to the amplifiers or the older adult would refuse to use the device.

CONCLUSION

This article highlights successes of the training as well as ideas for future trainings suggested by staff members. A key finding was the need to identify a core group of staff members who would be charged with facilitating use of personal amplification for older adults in the organization. In addition, providing multiple brief trainings over time was suggested to improve adoption of good communication practices among staff. [Journal of Gerontological Nursing, 50(4), 48-56.].

The genetic landscape of age-related hearing loss

Age-related hearing loss (ARHL) is a prevalent concern in the elderly population. Recent genome-wide and phenome-wide association studies (GWASs and PheWASs) have delved into the identification of causative variants and the understanding of pleiotropy, highlighting the polygenic intricacies of this complex condition. While recent large-scale GWASs have pinpointed significant SNPs and risk variants associated with ARHL, the detailed mechanisms, encompassing both genetic and epigenetic modifications, remain to be fully elucidated. This review presents the latest advances in association studies, integrating findings from both human studies and model organisms. By juxtaposing historical perspectives with contemporary genomics, we aim to catalyze innovative research and foster the development of novel therapeutic strategies for ARHL.

Hearing Loss, Hearing Aid Use, and Risk of Dementia in Older Adults

Importance

Hearing loss has been suggested as a risk factor for dementia, but there is still a need for high-quality research to better understand the association between these 2 conditions and the underlying causal mechanisms and treatment benefits using larger cohorts and detailed data.

Objective

To investigate the association between hearing loss and incident dementia, as well as how hearing aid use contributes to this association.

Design, Setting, and Participants

This population-based cohort study was conducted in Southern Denmark between January 2003 and December 2017 and included all residents 50 years and older. We excluded all persons with dementia before baseline as well as those who did not live in the region 5 years before baseline, with incomplete address history, or who had missing covariate information.

Exposures

Individual hearing status based on the Hearing Examinations in Southern Denmark database, which contains data on all pure-tone audiometry examinations performed at public hearing rehabilitation clinics in Southern Denmark.

Main Outcomes and Measures

Incident cases of dementia and Alzheimer disease as identified from national registries.

Results

The study population comprised 573 088 persons (298 006 women [52%]; mean [SD] age, 60.8 [11.3] years) with 23 023 cases of dementia and mean (SD) follow-up of 8.6 (4.3) years. Having a hearing loss was associated with an increased risk of dementia, with an adjusted hazard ratio (HR) of 1.07 (95% CI, 1.04-1.11) compared with having no hearing loss. Severe hearing loss in the better and worse ear was associated with a higher dementia risk, with an HR of 1.20 (95% CI, 1.09-1.32) and 1.13 (95% CI, 1.06-1.20), respectively, compared with having no hearing loss in the corresponding ear. Compared with people without hearing loss, the risk of dementia was higher among people with hearing loss who were not using hearing aids than those who had hearing loss and were using hearing aids, with HRs of 1.20 (95% CI, 1.13-1.27) and 1.06 (95% CI, 1.01-1.10), respectively.

Conclusions and Relevance

The results of this cohort study suggest that hearing loss was associated with increased dementia risk, especially among people not using hearing aids, suggesting that hearing aids might prevent or delay the onset and progression of dementia. The risk estimates were lower than in previous studies, highlighting the need for more high-quality longitudinal studies.
