ABSTRACT

IMPORTANCE Depression among hearing impaired US adults has not been studied previously. OBJECTIVE To estimate the prevalence of and risk factors for depression among adults with hearing loss. DESIGN, SETTING, AND PARTICIPANTS Adults aged 18 years or older (N = 18 318) who participated in the National Health and Nutrition Examination Survey (NHANES), 2005-2010, a nationally representative sample. INTERVENTIONS Multistage probability sampling of US population. MAIN OUTCOMES AND MEASURES Depression, assessed by the 9-item Patient Health Questionnaire (PHQ-9) scale, and hearing impairment (HI), assessed by self-report and audiometric examination for adults aged 70 years or older. RESULTS The prevalence of moderate to severe depression (PHQ-9 score, ≥10) was 4.9% for individuals reporting excellent hearing, 7.1% for those with good hearing, and 11.4% for participants who reported a little trouble or greater HI. Using excellent hearing as the reference, after adjusting for all covariates, multivariate odds ratios (ORs) for depression were 1.4 (95% CI, 1.1-1.8) for good hearing, 1.7 (1.3-2.2) for a little trouble, 2.4 (1.7-3.2) for moderate trouble, 1.5 (0.9-2.6) for a lot of trouble, and 0.6 (0.1-2.6) for deaf. Moderate HI (defined by better ear pure-tone average of hearing thresholds at 0.5, 1, 2, and 4 kHz within the range 35- to 49-dB hearing level) was significantly associated with depression among older women (OR, 3.9; 95% CI, 1.3-11.3), after adjusting for age, sex, race/ethnicity, lifestyle characteristics, and selected health conditions. CONCLUSIONS AND RELEVANCE After accounting for health conditions and other factors, including trouble seeing, self-reported HI and audiometrically determined HI were significantly associated with depression, particularly in women. Health care professionals should be aware of an increased risk for depression among adults with hearing loss.

    • "Some studies (Kim et al., 2010; Seomun & Lee, 2011) have reported that depression is the most important factor associated with elderly suicide ideation. There is also research on the association between hearing impairment and depression (Li et al., 2014), as well as a case report on the relation between vision loss in elderly individuals and suicide (Johnson, Rovner, & Haller, 2014). However, there is a relatively narrow understanding of suicide ideation among elderly persons; therefore, it seems necessary to further research the factors that influence suicide ideation, as well as the individual characteristics of elderly individuals that are associated with suicide ideation.

    ABSTRACT: Objectives: The purpose of this cross-sectional study was to examine the relationship between sensory impairment and suicide ideation among elderly Koreans. Methods: Data from the 2010-2012 Korea National Health and Nutrition Examination Survey V was used. Participants included 3636 older adults (≥65 years) who received hearing and vision tests; participants also completed assessments of covariates and suicide ideation. Results: The risk of suicide ideation was 1.43-1.65 times higher among participants with visual impairment than in those without impairment. Moreover, the risk was 1.60-1.76 times higher among those with both auditory and visual impairments than the risk for those without any impairment. Conclusion: This study found an association between sensory impairment and suicide ideation in elderly individuals. Therefore, it seems necessary that interventions that reduce or prevent sensory impaired elders' suicide ideation are needed, which may be an indicator of mental health problems or poor quality of life.

    • "Hearing loss can range from mild to profound, and can impact upon quality of life by affecting the development of language in children, and by having adverse educational and social ramifications. People with a severe hearing loss also typically have a much higher unemployment rate and a higher rate of mental health concerns such as depression [2]. "

    ABSTRACT: The cochlear implant provides auditory cues to profoundly deaf patients by electrically stimulating the primary auditory neurons (ANs) of the cochlea. However, ANs degenerate in deafness; the preservation of a robust AN target population, in combination with advances in cochlear implant technology, may provide improved hearing outcomes for cochlear implant patients. The exogenous delivery of neurotrophins such as brain-derived neurotrophic factor (BDNF) and neurotrophin-3 is well known to support AN survival in deafness, and cell-based therapies provide a potential clinically viable option for delivering neurotrophins into the deaf cochlea. This study utilized cells that were genetically modified to express BDNF and encapsulated in alginate microspheres, and investigated AN survival in the deaf guinea pig following (a) cell-based neurotrophin treatment in conjunction with chronic electrical stimulation from a cochlear implant, and (b) long-term cell-based neurotrophin delivery. In comparison to deafened controls, there was significantly greater AN survival following the cell-based neurotrophin treatment, and there were ongoing survival effects for at least six months. In addition, functional benefits were observed following cell-based neurotrophin treatment and chronic electrical stimulation, with a statistically significant decrease in electrically evoked auditory brainstem response thresholds observed during the experimental period. This study demonstrates that cell-based therapies, in conjunction with a cochlear implant, shows potential as a clinically transferable means of providing neurotrophin treatment to support AN survival in deafness. This technology also has the potential to deliver other therapeutic agents, and to be used in conjunction with other biomedical devices for the treatment of a variety of neurodegenerative conditions.
