A cross-sectional study of prevalence and correlates of self-harm and suicidal ideation in older adults with dual sensory loss

BACKGROUND

Loss of vision and hearing (dual sensory loss: DSL) presents risk factors for self-harm and/or suicidal ideation, although this has rarely been examined for older adults.

OBJECTIVES

This study estimated the prevalence of thoughts about self-harm and suicide ideation in a national sample of adults with DSL in Denmark.

METHODS

All 513 people aged 50 years or older who were registered with the national provider of service for people with DSL in Denmark were eligible to participate. Surveys were returned by 290 participants. Participants were mostly female (70%) and aged 50-100 years (M = 81). Surveys contained questions related to thoughts of self-harm and suicide as well as physical, mental, and social wellbeing.

RESULTS

In total, 17% of participants reported thoughts of self-harm and/or suicide in the past two weeks. Not participating in social activities, poorer self-rated health, and presence of more depressive symptoms were associated with self-harm and suicidal ideation. Factors that were associated with self-harm and suicidal ideation were lower levels of emotional support, non-participation in social activities, and symptoms of depression.

CONCLUSIONS

These finding highlight the importance of ongoing mental health screening and support for older adults with DSL, especially in ensuring accessible mental health services.

A dimensional approach to understanding the relationship between self-reported hearing loss and depression over 12 years: the Three-City study

Objectives: To examine the relationship between hearing loss and depression in older adults longitudinally. This paper uses a dimensional approach to conceptualising depression, with the aim of further enhancing understanding of this relationship.Method: 8344 community-dwelling adults aged 65 years and above enrolled in the Three-City prospective cohort study were included. Relationships between baseline self-reported hearing loss (HL) with the trajectory of different dimensions of depression symptoms over 12 years were examined using linear mixed models. Depression dimensions were determined using the four-factor structure of the Centre for Epidemiology Studies-Depression Scale (CESD): depressed affect, positive affect, somatic symptoms and interpersonal problems.Results: HL was associated with somatic symptoms of depression both at baseline (b = .07, p = .04) and over 12 years (b = .01, p = .04). HL was associated with poorer depressed affect and interpersonal problems at baseline (b = .05, p = .001, b = .35, p < .001; respectively), but not over follow-up. HL was associated with poorer positive affect symptoms over time (b = -.01, p = .01).Conclusion: HL had varied relationships with different dimensions of depression symptoms, and there were different patterns of adjustment for the dimensions. HL was primarily associated with somatic symptoms, suggesting that shared disease processes might partly underlie the relationship between HL and depression. Targeted assessment and treatment of somatic and positive affect symptoms in older adults with HL might facilitate better wellbeing in this population.

Third-Party Impact of Dual Sensory Loss on Neuropsychiatric Symptom-Related Distress among Friends and Family

BACKGROUND

Vision loss and hearing loss are common in later life and are associated with cognitive impairment and neuropsychiatric symptoms. There is a need to better understand how individual characteristics, such as poor sensory functioning, are linked with familial well-being.

OBJECTIVES

The aim of this study was to investigate whether, among persons with neuropsychiatric symptoms, age-related sensory loss is related to increased emotional distress reported by their family and friends.

METHODS

The sample comprised 537 participant-informant dyads from the Personality and Total Health through Life (PATH) study, a community-based cohort. Participants were aged between 72 and 79 years (56% men), and all were reported to exhibit at least 1 neuropsychiatric symptom. Informants were participants' spouse (50%), child (35%), friend (7%), or other relatives (7%). Neuropsychiatric symptom-related distress of friends and family was assessed with the distress subscale of the Neuropsychiatric Inventory (NPI). Sensory functioning in participants was assessed by visual acuity and self-reported hearing difficulties. Ordinal logistic regression analyses estimated the association between sensory problems and NPI distress.

RESULTS

In models adjusted for informant dyadic relationship and socio-demographics, both lower visual acuity (B = 0.23, SE = 0.10) and self-reported hearing difficulty (B = 0.15, SE = 0.06) were associated with increased levels of distress. The increased informant distress associated with poor visual acuity was attenuated after adjusting for neurocognitive disorder and health conditions (p = 0.069). A significant interaction between vision and hearing remained after multivariable adjustment (χ2(1) = 6.73, p = 0.010).

CONCLUSIONS

Friends and family of persons with poor visual acuity and perceived hearing difficulties report elevated levels of neuropsychiatric symptom-related distress relative to friends and family of persons with poor sensory functioning in only 1 sensory domain or unimpaired levels of vision and hearing. These findings provide evidence of the third-party effects of sensory loss in the context of neuropsychiatric symptoms, and in particular show how dual sensory loss can confer additional challenges over and above the effects of a single sensory loss.
