Hearing aids for mild to moderate hearing loss in adults

Ferguson MA, et al. | Hearing aids for mild to moderate hearing loss in adults Cochrane Database of Systematic Reviews 2017, Issue 9. | Published online 25th September 2017

This study reviewed the evidence on the effects that hearing aids have on everyday life in adults with mild to moderate hearing loss. Authors were interested in (1) a person’s ability to take part in everyday situations, (2) general health-related quality of life, (3) ability to listen to other people, and (4) harm, such as pain or over-exposure to noise.

Background

The main goal of hearing aids is to reduce the impact of hearing loss and to improve a person’s ability to take part in everyday life. Although hearing aids are the most common technology for adults with hearing loss and are in widespread use, it is not clear how beneficial they are.

Study characteristics

The evidence is up to date to 23 March 2017. Authors found five clinical studies involving 825 adults with mild to moderate hearing loss who were randomly given either hearing aids, no hearing aids or placebo hearing aids. Studies involved older adults with the average age within studies between 69 and 83 years. The duration of the studies was between six weeks and six months.

Key results

Evidence was found in three studies that hearing aids have a large beneficial effect in improving the ability of adults with mild to moderate hearing loss to take part in everyday situations. Hearing aids have a small beneficial effect in improving general health-related quality of life, such as physical, social, emotional and mental well-being, and have a large effect in improving the ability to listen to other people.

Only one study attempted to measure harms due to hearing aids. None were reported.

Conclusions

This review found that hearing aids improve the ability of adults with mild to moderate hearing loss to take part in everyday life, their general quality of life and their ability to listen to other people. If an adult with mild to moderate hearing loss seeks help for their hearing difficulties, hearing aids are an effective clinical option. It is important that future studies measure benefits consistently and report benefits separately for different age groups, genders, levels of hearing loss and types of hearing aids.

One hundred and thirteen adults, aged ≥ 50 years, with postlingual hearing loss and receiving routine clinical care at a tertiary academic medical center, were evaluated with the University of California at Los Angeles Loneliness Scale before and 6 and 12 months after intervention with HAs or CIs. Change in score was assessed using linear mixed effect models adjusted for age; gender; education; and history of hypertension, diabetes, and smoking.

Treatment of hearing loss with CIs results in a significant reduction in loneliness symptoms. This improvement was not observed with HAs. We observed differential effects of treatment depending on the baseline loneliness score, with the greatest improvements observed in individuals with the most loneliness symptoms at baseline.

Association of Hearing Impairment and Subsequent Driving Mobility in Older Adults

Hearing impairment (HI) is associated with driving safety (e.g., increased crashes and poor on-road driving performance). However, little is known about HI and driving mobility | The Gerontologist

Purpose of the Study: This study examined the longitudinal association of audiometric hearing with older adults’ driving mobility over 3 years.

Results: Individuals with moderate or greater HI performed poorly on the UFOV, indicating increased risk for adverse driving events (p < .001). No significant differences were found among older adults with varying levels of HI for driving mobility (p values > .05), including driving cessation rates (p = .38), across time.

Implications: Although prior research indicates older adults with HI may be at higher risk for crashes, they may not modify driving over time. Further exploration of this issue is required to optimize efforts to improve driving safety and mobility among older adults.

The Association between Hearing Loss, Postural Control, and Mobility in Older Adults

Degraded hearing in older adults has been associated with reduced postural control and higher risk of falls. Both hearing loss (HL) and falls have dramatic effects on older persons’ quality of life (QoL). A large body of research explored the comorbidity between the two domains | Journal of the American Academy of Audiology

Purpose: The aim of the current review is to describe the comorbidity between HL and objective measures of postural control, to offer potential mechanisms underlying this relationship, and to discuss the clinical implications of this comorbidity.

 

Results: Of 211 screened articles, 7 were included in the systematic review. A significant, positive association between HL and several objective measures of postural control was found in all seven studies, even after controlling for major covariates. Severity of hearing impairment was connected to higher prevalence of difficulties in walking and falls. Physiological, cognitive, and behavioral processes that may influence auditory system and postural control were suggested as potential explanations for the association between HL and postural control.

Conclusions: There is evidence for the independent relationship between HL and objective measures of postural control in the elderly. However, a more comprehensive understanding of the mechanisms underlying this relationship is yet to be elucidated. Concurrent diagnosis, treatment, and rehabilitation of these two modalities may reduce falls and increase QoL in older adults.

Aim: The research aim was to explore the influence of hearing problems, various coping strategies, and perceived social support on quality of life.

Results: Quality of life was predicted by perceived social support and the number of comorbid diseases (i.e., the physical, psychological, environmental, and social quality of life was better the greater the extent of perceived social support and poorer the more diseases from which the participants suffered).

Conclusions: Perceived social support may be a relevant factor to focus on in auditory rehabilitation programs, in particular, for participants who communicate little support in hearing-related situations and are, hence, at a relative disadvantage. The involvement of significant others in counseling could facilitate the everyday life for older adults with age-related hearing loss and their significant others

Why is Hearing Loss a Public Health Concern?

Tremblay, K. L. (2017) Hearing Journal. 70(4) pp. 14,16

‘Answer: Because hearing loss is highly prevalent, with numerous associated health risks that burden affected individuals, their family, and their community.’

When hearing loss is viewed from a public health perspective, the mission expands to include improving health and quality of life, not only through prevention and treatment of hearing loss but also through the promotion of healthy behaviors. An essential component of public health is the “collective action for sustained population-wide health improvement” (Lancet. 2004;363[9426]:2084 http://bit.ly/2lALIIj; Bull World Health Organ. 2014;92[5]:367 http://bit.ly/2lAFqIq). As such, there are many ongoing initiatives aimed at making hearing health care more accessible and affordable within and outside of the medical model (Ear Hear. 2016;37[4]:376 http://bit.ly/2lAL6SW; Ear Hear. 2010;31[1]:2 http://bit.ly/2lAIMew).

Recurrent acute otitis media detracts from health-related quality of life

Kujala T. et al. (2017) The Journal of Laryngology & Otology. 131(2) pp. 128-137

Acute otitis media causes discomfort to children and inconvenience to their parents. This study evaluated the quality of life in children with recurrent acute otitis media aged less than 24 months.

Quality of life was evaluated in 149 children aged 10 to 24 months who were referred to the Oulu University Hospital on account of recurrent acute otitis media. The children were treated with or without surgery. Age-matched controls were selected randomly from the general child population. Parents completed the Child Health Questionnaire.

The children with recurrent acute otitis media had a significantly poorer quality of life than control children. The control children with a history of a few acute otitis media episodes had a significantly poorer quality of life than those without any such history. The quality of life of the children with recurrent acute otitis media improved during the one-year follow up, regardless of the treatment, but did not reach the same level as healthy children.

Acute otitis media detracted from quality of life when a generic measure was used. The mode of treatment used to prevent further recurrences of acute otitis media did not influence quality of life improvement.
