Communication participation in older adults with dual sensory loss

Development of core sets for deafblindness using the International Classification of Functioning, Disability, and Health: the perspectives of individuals with lived experience

BACKGROUND

The needs of people with deafblindness remain poorly understood and addressed globally. This study is part of a larger body of work to develop Core Sets for deafblindness using the International Classification of Functioning, Disability, and Health (ICF).

AIM

To determine the perspectives on functioning of individuals with lived experience of deafblindness as they relate to the ICF.

DESIGN

Cross-sectional interview study.

SETTING

Global, representing all six regions of the World Health Organization.

POPULATION

A diverse cohort of 72 individuals living with deafblindness or as close family members, ranging across the spectrum of severity.

METHODS

Qualitative interviews and focus groups were used to explore six open-ended questions about perceived barriers and facilitators to functioning of body functions and structures, activities and participation, and environmental and personal factors. Data were synthesized using content analysis, and the resulting topics were linked to the ICF codes using established linking methodology prescribed by the World Health Organization's ICF Research Branch. Descriptive statistics summarized all demographic data.

RESULTS

The analyses of the transcripts uncovered 2534 meaning units, leading to the identification of 492 corresponding distinct codes from the ICF framework, and spanning across 93.33% of coding categories available. Sensory (b2) and Mental Functions (b1) emerged as the most frequent Body Functions (b) codes. Most categories referred to Activities & Participation, with Mobility (d4) being the most frequently mentioned topic. Services, Systems and Policies (e5) was the most frequently used Environmental factor.

CONCLUSIONS

Over 93% of the ICF classification categories were accessed to code the data provided by participants, demonstrating the complexity of functioning with deafblindness. This study provides valuable information to shape policy and research by providing representation of lived experience towards the consensus conference for the comprehensive and abbreviated Core Sets for deafblindness.

CLINICAL REHABILITATION IMPACT

The inclusion of lived experience provides a holistic understanding of the daily challenges faced by individuals living with deafblindness. By being part of this process, they have a voice in shaping the classification system that will be used to describe their experiences, fostering a sense of ownership and empowerment.

A study on the mechanism of how sensory impairment affects depression in the elderly: the mediating roles of daily activity capability and social participation

Objectives

Through a longitudinal study, we explored the relationship between sensory impairments and depression in the elderly, and examined the mediating roles of daily activity capability and social participation within this relationship.

Methods

Based on data from the China Health and Retirement Longitudinal Study (CHARLS) collected in 2015 and 2018, a total of 4,419 individuals aged 60 and above were selected as research participants. Sensory impairments (predictor variables) were assessed in 2015 through self-rated visual and hearing capabilities. Daily activity capability and social participation (mediator variables) were also assessed in 2015, with daily activities assessed using the Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL), and social participation assessed by the quantity of social activity participation. Depression status (outcome variable) was assessed in 2018 using the Center for Epidemiologic Studies Depression Scale (CESD-10). Statistical analysis was conducted using logistic regression and SPSS Macro PROCESS.

Results

First, there is a significant correlation between sensory impairments and an increased risk of depression among the elderly, including visual impairment (VI), hearing impairment (HI), and dual sensory impairment (DSI), all of which increase the likelihood of depression. Second, DSI indirectly affect depression through the cascading mediating effects of daily activity capability and social participation. Finally, in contrast to DSI, when there is only a single sensory impairment, either VI or HI, the cascading mediating effects of daily activity capability and social participation on depression are not statistically significant.

Conclusion

The elderly population with dual sensory impairments requires continued attention to help these individuals adopt preventive measures to halt the onset and worsening of depression.

Hearing and vision impairment and social isolation over 8 years in community-dwelling older adults

BACKGROUND

Little is known about the long-term impact of hearing and vision impairment on social isolation. This study quantifies the association between hearing, vision, and concurrent hearing and vision impairment (dual sensory impairment) and social isolation over 8 years among older adults.

METHODS

Data were from the National Health and Aging Trends Study (NHATS), a cohort study (2011 - 2019) of U.S. Medicare beneficiaries aged 65 years and older. Social isolation was measured by a binary indicator incorporating four domains: living arrangement, core discussion network size, religious attendance, and social participation. Hearing, vision, and dual sensory impairments were measured by self-report and modeled categorically (no impairment [ref.], hearing impairment only, vision impairment only, dual sensory impairment). Associations between sensory impairments and odds of social isolation over 8 years were assessed using multivariate generalized logistic mixed models and adjusted for demographic and health characteristics.

RESULTS

Among 5,552 participants, 18.9% self-reported hearing impairment, 4.8% self-reported vision impairment, and 2.3% self-reported dual sensory impairment. Over 8 years, hearing impairment only was associated with 28% greater odds of social isolation. Participants with hearing impairment only were more likely to live alone and have limited social participation.

CONCLUSION

Greater clinical awareness of hearing impairment as a risk factor for social isolation can increase opportunities to identify and aid older adults who may benefit from resources and interventions to increase social connection and mitigate social isolation.

Vision and Hearing Difficulties and Life Expectancy Without ADL/IADL Limitations: Evidence From the English Longitudinal Study of Ageing and the Health and Retirement Study

BACKGROUND

Hearing and vision difficulties are some of the most common deficits experienced by older adults. Having either visual or hearing difficulties increases the risk of comorbidity, disability, and poor quality of life. So far, however, few studies have examined the association between vision and hearing difficulties on life expectancy without activities of daily living (ADL) or instrumental ADL (IADL) limitations (LEWL).

METHODS

Data came from the English Longitudinal Study of Ageing and the Health and Retirement Study in the United States from 2002 to 2013. The outcome was defined as reporting 2+ limitations with ADL/IADL. Life expectancy was estimated by discrete-time multistate life table models for hearing and vision difficulties separately as well as for combined vision and hearing difficulties by sex and age.

RESULTS

Thirteen percent of men in England and the United States had ADL/IADL limitations, whereas, for women, it was 16% and 19% in England and the United States. At all ages, either vision or hearing difficulty was associated with shorter LEWL compared to no difficulties. Dual sensory difficulty (vision and hearing) reduced LEWL by up to 12 years in both countries. At the ages of 50 and 60 in England, hearing difficulty was associated with fewer years lived without ADL/IADL limitations than vision difficulty. In contrast, in the United States, vision difficulty led to fewer years lived without ADL/IADL limitations than hearing difficulty.

CONCLUSIONS

The implementation of strategies to reduce the prevalence and incidence of vision and hearing difficulties has the potential to increase the number of years spent without ADL/IADL limitations.

Dual Sensory Impairment as a Predictor of Loneliness and Isolation in Older Adults: National Cohort Study

BACKGROUND

Loneliness and social isolation are global public health challenges. Sensory impairments (SIs) are highly prevalent among older adults but are often ignored as a part of normal aging. Identifying the role of SIs in loneliness and social isolation could provide insight into strategies for improving public health among older adults.

OBJECTIVE

This study aims to analyze the effects of SIs on loneliness and social isolation among older adults in rural and urban China.

METHODS

This cohort study of 3069 older adults (aged 60+) used data from 4 waves (2011, 2013, 2015, and 2018) of the China Health and Retirement Longitudinal Study (CHARLS), a nationally representative survey of adults aged 45 years or older. SIs include hearing impairment (HI), vision impairment (VI), and dual sensory impairment (DSI). DSI is defined as the co-occurrence of VI and HI. Participants with complete data on hearing, vision, social isolation, and loneliness were included in the analysis. Generalized estimating equation models adjusted for covariates were used to examine the relationships of DSI with loneliness and social isolation among older adults.

RESULTS

Older adults in rural areas have higher prevalence of DSI, loneliness, and social isolation than their urban counterparts. In rural areas, participants with VI only (odds ratio [OR] 1.34, 95% CI 1.12-1.62; P=.002), HI only (OR 1.32, 95% CI 1.02-1.71; P=.03), and DSI (OR 1.84, 95% CI 1.56-2.18; P<.001) were more likely to experience loneliness compared with participants without SIs. DSI showed a statistically significant association with loneliness compared with VI only (OR 1.37, 95% CI 1.22-1.54; P<.001) and HI only (OR 1.39, 95% CI 1.13-1.72; P=.002). In urban areas, participants with VI only (OR 2.44, 95% CI 1.57-3.80; P<.001), HI only (OR 2.47, 95% CI 1.41-4.32; P=.002), and DSI (OR 1.88, 95% CI 1.24-2.85; P=.003) were more likely to experience loneliness compared with participants without SIs. DSI was not associated with the increased likelihood of loneliness compared with HI only or VI only. SIs were not associated with social isolation among older adults in urban and rural areas. Until 2018, 86.97% (2669/3069) reported VI, but only 27.11% (832/3069) and 9.45% (290/3069) were treated with glasses and cataract surgery, respectively; besides, 75 individuals received both glasses and cataract surgery treatment. The prevalence of HI was 74.39% (2283/3069) in 2018, but only 0.72% (22/3069) were treated with a hearing aid.

CONCLUSIONS

SIs are associated with an increased risk of loneliness rather than social isolation. A compounded risk of DSI on loneliness exists in rural areas rather than in urban areas. These findings expand our knowledge about the effects of SIs on loneliness and social isolation in non-Western populations. Interventions targeting HI only and DSI might be particularly effective for mitigating loneliness of older adults in urban and rural areas, respectively. Considering the high prevalence and low treatment rate of SIs, measures should be taken to make treatment more accessible.

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.
