Hearing aid rehabilitation: what do older people want and what does the audiogram tell?

The association between non-communicable disease and hearing aid adoption in older adults with hearing loss

Objective: To assess whether specific non-communicable diseases are associated with hearing aid adoption in older adults with hearing loss.Design: A cross-sectional, observational study.Study sample: Data was obtained from one of the largest pharmacy-led health and beauty retailers in the United Kingdom. In total, 17,172 older adults were included.Results: Greater odds of adopting hearing aids were associated with being older (Odds ratio [OR] = 1.03; 95% confidence interval [CI] = 1.02, 1.03), having fewer self-reported hearing difficulties (OR = 0.61; 95% CI = 0.58, 0.64), and greater audiometric hearing loss (OR = 1.68; 95% CI = 1.54, 1.83). The odds of adopting hearing aids were lower if individuals self-reported hypertension (OR = 0.87; 95% CI = 0.79, 0.97) and diabetes (OR = 0.83; 95% CI = 0.72, 0.95). Using a decision tree model, self-reported hearing difficulties, audiometric hearing loss, and age were the best combination of variables to differentiate between individuals that did and did not adopt hearing aids.Conclusions: This study demonstrates that hearing aid adoption is lower in older adults with cardiovascular disease risk factors. Thus, there is a need for healthcare professionals to identify older adults living with hearing loss and cardiovascular ill-health, ensuring that they receive appropriate patient-centred support to manage their health.

Trajectories of older adults' hearing difficulties: examining the influence of health behaviors and social activity over 10 years

AIM

The aims of the present study were to describe the trajectories of self-reported hearing difficulties over time, and evaluate the impacts of age, sex, lifestyle factors and social activity, in explaining individual differences in patterns of change over time.

METHODS

As part of the Melbourne Longitudinal Studies on Healthy Aging (MELSHA) Program, the hearing status of 947 adults aged 65 years and older, across five measurement periods (over 10 years), were analyzed using Latent Growth Curve Modeling analysis. A multidimensional survey was also administered, which included questions relating to sociodemographic variables, self-reported hearing difficulties, nutrition, smoking habits and level of social activity.

RESULTS

Although there was a general increase in hearing difficulties over time, older age, poor nutrition, a lifetime of smoking and increased social activity predicted more rapid increases in hearing difficulty over time.

CONCLUSIONS

Findings support the importance of lifestyle factors in reducing the rate of perceived hearing difficulties in older people, and provide further evidence of the links between lifestyle and sensory loss in older people. Poor nutrition and smoking are areas that both clinicians and public health professionals should address in their work with older people.

Predictors of rehabilitation intervention decisions in adults with acquired hearing impairment

PURPOSE

This study investigated the predictors of rehabilitation intervention decisions in middle-age and older adults with acquired hearing impairment seeking help for the first time.

METHOD

Using shared decision making, 139 participants were offered intervention options: hearing aids, communication programs (group or individual), and no intervention. Multivariate analysis (logistic regression) provided odds ratios and 95% confidence intervals for intervention decision predictors when all other variables were held constant.

RESULTS

Seven intervention decision predictors were identified: (a) application for subsidized hearing services (participants more likely to choose hearing aids and less likely to choose communication programs), (b) hearing impairment (hearing aids more likely and no intervention less likely), (c) communication self-efficacy (hearing aids less likely), (d) powerful others as locus of control (hearing aids less likely), (e) hearing disability perceived by others and self (hearing aids more likely), (f) perceived communication program effectiveness (communication programs more likely), and (g) perceived suitability of individual communication program (hearing aids less likely and communication programs more likely).

CONCLUSION

Findings suggest the need for clinicians to explicitly elicit the predictors identified by this study when involving adults with acquired hearing impairment in intervention decisions.

A health policy for hearing impairment in older Australians: what should it include?

Background

As in all western countries, Australia's older population experiences high levels of hearing impairment coupled with relatively low levels of hearing device usage. Poor hearing diminishes the quality of life of affected individuals and their families. This paper discusses how to improve Australian hearing health policies in order to better combat this impairment amongst older Australians.

Method

We searched the databases Medline, Meditext and Web of Science to find articles that discussed strategies and innovations to assist the hearing health of older people, and related this material to observations made during the Blue Mountains Hearing Study in NSW between 1997 and 2003.

Results and Discussion

The literature search identified five areas for inclusion in a comprehensive hearing health policy in Australia. These are: early intervention; addressing of hearing aid expense; the use of assisted listening devices; hearing rehabilitation, and; screening and education. Further research in Australia is critical if we are to develop a strong approach to the increasing prevalence of age-related hearing loss.

Conclusion

Australia needs to act now to address hearing impairment as it is a major cause of disability in those aged 55 and over. Federal and State governments should collaborate to construct a comprehensive hearing health policy that tackles poor levels of hearing health through early intervention, addressing hearing aid expense, encouraging the use of assisted listening devices, rehabilitation, screening and education. A good start would be to declare age related hearing impairment as a National Health Priority Area.
