Home but still engaged: participation in social activities among the homebound

Depressive/Anxiety Symptoms in Homebound Older Adults: Mediation Effects of Loneliness and Psychological Well-Being

OBJECTIVES

To examine the direct effect of a homebound state (defined as never/rarely going outside the home in the preceding month) on depressive/anxiety symptoms and the mediation effect of loneliness and psychological well-being on the associations between homebound state and depressive/anxiety symptoms.

METHODS

Data came from the 2023 National Health and Aging Trend Study (N = 7,547 community-dwelling Medicare beneficiaries age 65+). We fitted a path model to examine the research questions. To test the statistical significance of the mediation effect, we used bootstrapped analysis to obtain estimates of the indirect effects and their 95% CIs.

RESULTS

We found significant direct and indirect effects. The ratio of the indirect effect of loneliness on a homebound state (0.13) to the total effect of a homebound state on depressive/anxiety symptoms was 0.14. The ratio of the indirect effect of psychological well-being on a homebound state (0.28) to the total effect of a homebound state on depressive/anxiety symptoms was 0.26.

CONCLUSIONS

Loneliness and psychological well-being, or lack thereof, significantly mediate the relationship between homebound state and depression/anxiety in homebound older adults.

CLINICAL IMPLICATIONS

Interventions to decrease loneliness and improve psychological well-being among homebound older adults are needed to alleviate their depression/anxiety.

Association between formal social participation and cognitive function in middle-aged and older adults: a longitudinal study using SHARE data

Formal social participation significantly impacts health and well-being, potentially mitigating cognitive decline, although not consistently across all studies. Existing research often focuses solely on baseline participation levels, and age-related differences have primarily been explored among the Asian population. Therefore, this longitudinal study aims to assess the association between formal social participation and cognition across different age groups in individuals aged 50+ living in Europe and Israel, while capturing the dynamic nature of formal social participation. We use data from three waves (four, six, and eight) of the Survey of Health, Ageing, and Retirement in Europe (SHARE), comprising 85,601 respondents. Linear mixed-effects models were applied. The results show that participation in formal social activities mitigates cognitive decline in middle-aged and older adults, especially among those aged 70 to 79 and 80+. These findings support the need for social policies promoting formal social activities, for lasting cognitive health benefits.

Longitudinal mediation effects of activity meaning on the association between activity performance and quality of life among older adults with disabilities

BACKGROUND

Physical limitations may hinder older adults with physical disabilities' capability to perform various activities, which can affect their quality of life (QOL). Accomplishing meaningful activities may mitigate the impact of limited activity performance on their QOL. This longitudinal study aims to investigate how activity meaning mediates the relationship between activity performance and QOL among older adults with disabilities.

METHODS

Data for this longitudinal study was collected from 813 community-dwelling older adults aged 60 and above who had physical disabilities, over a two year interval. Path analysis was used to examine the cross-sectional and longitudinal mediation effects from activity performance, through activity meaning, to QOL.

RESULTS

At the same wave, high IADL performance or social activity performance, and high QOL was indirectly associated through high IADL meaning or social meaning. As for longitudinal association, high T1 IADL performance was associated with better T2 QOL through high T1 and T2 IADL meaning. Similarly, high T1 social activity performance also contributed to T2 QOL through high T1 and T2 social activity meaning. Additionally, social activity performance exhibited higher influence on QOL than that of IADL.

CONCLUSIONS

Both IADL and social activities have distinct impacts on the QOL of older adults with disabilities. To improve the current and future QOL of older adults with disabilities, professionals must prioritize their involvement in the most meaningful activities while being sensitive to and supportive of their preferences and valued lifestyles.

Patterns of Healthcare Utilization and Spending Among Homebound Older Adults in the USA: an Observational Study

BACKGROUND

Homebound older adults have complex social, medical, and financial needs, but little is known about their healthcare utilization and spending.

OBJECTIVE

To characterize healthcare utilization and spending among homebound older adults.

DESIGN

Cohort study using National Health and Aging Trends Study data linked to Medicare Fee-for-Service (FFS) claims data.

PARTICIPANTS

Adults aged 70 years and older with Medicare FFS coverage (n = 6468).

MAIN MEASURES

In a person-year analysis, survey-weighted rates and adjusted marginal differences in inpatient, outpatient, and emergency department utilization and spending 12 months post-interview were calculated by homebound status, defined as reporting never or rarely (no more than 1 day/week) leaving home in the last month.

KEY RESULTS

Compared to the non-homebound, homebound observations had lower annual unadjusted rates of accessing primary care (60.9% vs 71.9%, p < 0.001) and specialist care (61.0% vs 74.9%, p < 0.001) and higher annual rates of emergency department use (54.0% vs 32.6%, p < 0.001) and hospitalization (39.8% vs 19.8%, p < 0.001). Total annual Medicare spending was $11,346 higher among the homebound compared to the non-homebound (p < 0.001). In a single year analysis (2015), homebound older adults accounted for 11.0% of Medicare spending among those over 70 despite making up only 5.7% of this population. 13.6% of the homebound were in the 95th percentile or above of Medicare spending in 2015. In models adjusting for demographic, clinical, and geographic characteristics, homebound status was associated with a decreased likelihood of having an annual primary care or specialist visit and $2226 additional total annual Medicare spending.

CONCLUSIONS

Homebound older adults use more hospital-based care and less outpatient care than the non-homebound, contributing to higher levels of overall Medicare spending.

Life-space mobility in older adults with Alzheimer's-type dementia

BACKGROUND

Mobility is an important component of functioning. Motor and cognitive impairment in older people with Alzheimer's disease can exert a negative impact on life-space mobility.

OBJECTIVE

To compare life-space mobility in older adults with mild and moderate Alzheimer-type dementia and those without dementia and determine associations with health factors.

METHODS

Life-space mobility was assessed using the Life Space Assessment (LSA) in 33 older adults with Alzheimer-type dementia (AD group) and 24 older adults without dementia (WD group). The World Health Organization Disability Assessment Schedule (WHODAS 2.0), Addenbrooke's Cognitive Examination (ACE-R), Geriatric Depression Scale (GDS), Modified Baecke Questionnaire for Older Adults (MBQOA), and Short Physical Performance Battery (SPPB) were completed. Statistical analysis was performed with unpaired t-test or Mann-Whitney tests for comparisons between groups and Spearman's correlation test.

RESULTS

The AD group had a lower total LSA score compared to the WD group (44 vs 65, mean difference = -20.7 [95% CI: -28.6, -12.9]), 21% of the AD group were restricted to their homes when no assistance was available. In both groups, moderate correlations were found between LSA and both functioning and physical activity level. Symptoms of depression presented moderate correlation only in the WD group.

CONCLUSIONS

Older adults with AD have lower life-space mobility and require assistance to achieve higher levels of mobility.

CLINICAL IMPLICATIONS

LSA can help assess life-space mobility. Encouraging and enabling assistance is fundamental to a greater life-space for older adults with dementia.

Cost-effectiveness of Tele-delivered behavioral activation by Lay counselors for homebound older adults with depression

BACKGROUND

Low-income homebound older adults have limited access to psychosocial treatments because of their homebound state and geriatric mental health workforce shortages. Little is known about cost effectiveness of lay-counselor-delivered, videoconferenced, short-term behavioral activation on this study population. The objective of this study was to assess the cost-effectiveness of lay-counselor-delivered, videoconferenced, short-term behavioral activation (Tele-BA) compared to clinician-delivered, videoconferenced problem-solving therapy (Tele-PST) and telephone support calls (attention control; AC) for low-income homebound older adults.

METHODS

We performed a cost-effectiveness analysis based on data from a recently completed, 3-group (Tele-BA, Tele-PST, and AC) randomized controlled trial with 277 participants aged 50+. We measured total costs of (1) intervention and (2) outpatient care, ED visits, and inpatient care using the Cornell Services Index. The effectiveness outcome was quality-adjusted life-years (QALY). We used EuroQol's EQ-5D-5L to assess each participant's health-related quality of life (HRQoL) at baseline and at 12, 24, and 36 weeks. The end-point measure of cost-effectiveness was the incremental cost-effectiveness ratio (ICER) of (1) Tele-BA versus AC, (2) Tele-PST versus AC, and (3) Tele-BA versus Tele-PST.

RESULTS

Relative to AC, both Tele-BA and Tele-PST are cost-saving treatment options. The ICERs for both Tele-BA and Tele-PST were well below $50,000, the lower-bound threshold for cost-effectiveness. Relative to AC, both Tele-PST, Tele-BA are cost-saving treatment options (i.e. lower costs and more QALYs).

CONCLUSION

Costs of tele- and lay-counselor-delivered depression treatment are modest and cost effective relative to providing telephone support. Though our results show that Tele-BA may not be cost effective relative to Tele-PST, a clinician-delivered psychotherapy, when a low bound ICER threshold of $50,000 would be used, lay counselors can fill the professional geriatric mental health workforce shortage gap and Tele-BA by lay counselors can improve homebound older adults' access to evidence-and skills-based, cost effective depression care.

Home, but Not Homebound: A Prospective Analysis of Persons Living With Dementia

OBJECTIVES

Homebound persons living with dementia may have increased difficulty accessing needed care in the community. This study identifies factors associated with becoming homebound among a national sample of Medicare beneficiaries with newly identified dementia.

DESIGN

Prospective cohort analysis.

SETTING AND PARTICIPANTS

We used the National Health and Aging Trends Study (NHATS) 2011-2018 to identify community-dwelling older adults at the time of a new dementia diagnosis (n = 939). Dementia status was determined based on cognitive testing and self and proxy reporting.

METHODS

We compared characteristics of homebound (ie, those who never or rarely left home) and non-homebound participants at the time of dementia identification. Among non-homebound participants, we used a Fine-Gray subdistribution hazard model to identify factors associated with becoming homebound over follow-up (median follow-up 4 years), accounting for competing risks of death and moving to a nursing home.

RESULTS

20% of individuals with newly identified dementia were homebound and this group was more functionally impaired, medically complex, and socioeconomically disadvantaged as compared to the non-homebound. Over time, depression [subhazard ratio (SHR) 2.19, 95% CI 1.36, 3.54], living in an assisted living facility (SHR 2.60, 95% CI 1.35, 4.97), and Hispanic ethnicity (SHR 1.91, 95% CI 1.05, 3.47) were associated with becoming homebound.

CONCLUSIONS AND IMPLICATIONS

Most adults are not homebound at the time of dementia diagnosis. Identifying and addressing modifiable factors like depression may slow progression to homebound status and enable persons living with dementia to access needed care in the community. In order to accommodate diverse individual and family preferences for long-term care, robust systems of home-based clinical and long-term care are necessary for those who do become homebound.

'It's not just about the dinner; it's about everything else that we do': A qualitative study exploring how Meals on Wheels meet the needs of self-isolating adults during COVID-19

Meals on Wheels (MoWs), a service offered by local authorities in England, deliver meals to older, housebound and/or vulnerable adults, who might otherwise not be able to acquire and prepare their own meals. Research suggests that MoWs provide benefits beyond nutrition. Little is known about the actual interactions between service providers and clients, particularly during the COVID-19 pandemic. The aim of this small-scale, formative study was to explore MoWs service providers' experiences and their perceptions around the benefits and challenges faced by the service, and understand how these experiences changed during the first UK national lockdown. Semi-structured interviews were conducted in September 2020 with 18 service providers of MoWs (drivers who deliver the meals, service coordinators and managers) in two local authorities in England, and analysed thematically. Participants indicated that benefits of the service encompassed those to clients (e.g. welfare checks, encouraging independence and identifying and addressing isolation and loneliness), employees (e.g. sense of pride, rewarding relationships with clients) and the wider community (e.g. reducing pressures on families), and described MoWs as the 'fourth emergency service' (e.g. being the first responders to emergency situations). Participants identified several challenges faced by the MoWs service, including organisational challenges (e.g. funding cuts and closures, lack of appropriate publicity to raise awareness of the service) and restrictions on time spent with clients. The pandemic and lockdown resulted in increased demand on resources, concerns about client and staff wellbeing and uncertainty about how the service will cope if lockdowns continue. These findings provide important insights regarding the wide benefits of MoWs and the challenges the service faces, which can be used as the formative research base to guide future interventions and policies to protect vulnerable adults, not only during the COVID-19 pandemic, but beyond.

Measuring Social Engagement among Low-Income, Depressed Homebound Older Adults: Validation of the Social Engagement and Activities Questionnaire

Objectives: To investigate the psychometric properties of the 10-item Social Engagement and Activities Questionnaire (SEAQ) to assess social-group, interpersonal interaction, and solitary activities among low-income, depressed homebound older adults (n = 269).Methods: We used principal component analysis (PCA) to evaluate the underlying dimensions of the 10-item full SEAQ and a 6-item abbreviated item set. We assessed evidence of validity for the SEAQ by examining relationships between the SEAQ and older adults' clinical characteristics: perceived social support, disability, and depressive symptoms.Results: PCA results showed two components: (1) a general social-group activities engagement component; and (2) a low level of socialization (i.e., strong negative coefficients on the recreational activities and self-enrichment/educational activities and a negative coefficient for interpersonal interaction activities). The general social-group activities engagement component in both the full and abbreviated SEAQ were significantly positively correlated with the full and abbreviated SEAQ and perceived social support, providing evidence for convergent validity, and they were significantly negatively correlated with disability and depressive symptoms, providing evidence for discriminant validity.Conclusions: The present study provides evidence of validity for the use of the SEAQ to assess social engagement and activities among low-income, depressed homebound older adults.Clinical Implications: The SEAQ may be used in future studies measuring changes in social engagement and activities in these older adults.

Prospective assessment of dementia on transitions in homeboundness using multistate Markov models

BACKGROUND

One in 20 older adults in the United States is homebound and rarely/never leaves home. Although being homebound decreases the quality of the lived experience of individuals with serious illnesses, little is known about the frequency or likelihood of transitions in or out of homebound status. The objective of this study was to characterize the probability of transitions to and from homebound status among older adults and examine the relationship between dementia status and homebound transitions.

METHODS

Using 2011-2018 data from the National Health and Aging Trends Study (NHATS), a nationally representative longitudinal study of aging in the United States, we identified 6375 community-dwelling Medicare beneficiaries. Homebound status (independent, semi-homebound (leaving home but with difficulty or help), homebound (rarely or never leaving home), nursing home resident, dead) was assessed annually via self-report. Transition probabilities across states were assessed using a multistate Markov model.

RESULTS

Less than half of homebound individuals remain homebound (probability = 41.5% [95% CI: 39.2%, 43.5%]) after 1 year. One out of four dies (24% [22.3%, 26.0%]) and there is a low probability (3.2% [2.5%, 4.1%]) of transition to a nursing home. Dementia status was associated with increased risk of progression from independence to homebound status (HR: 1.83 [1.01, 3.34]). Dementia was consistently associated with increased probabilities of transitions to death including a two-fold increased hazards of progression from homebound to death (HR: 2.18 [1.69, 2.81]). Homebound individuals with dementia have a 34.2% [25.8%, 48.1%] probability of death in 5 years, compared with 17.4% [13.7%, 24.3%] among those without dementia.

DISCUSSION

Dementia is associated with greater risk of transitioning across homebound states. There is a greater need to support home-based care for patients with dementia, especially as the ongoing COVID pandemic has raised concerns about the need to invest in alternative models to nursing home care.

A perspective on the sense of loneliness and its determinants in Iranian older people

BACKGROUND

The sense of loneliness is one of the common problems of older people and their quality of life, and is affected by many factors such as personal resources, gender, health condition, and age. This study investigates the determinants of the sense of loneliness between older men and women in Birjand.

METHODS

This study was a part of the community-based prospective cohort study of the Birjand Longitudinal Aging Study (BLAS). Individuals over 60 years of age and their families (selected by random cluster sampling) were assessed through structured interviews with questionnaires such as Patient Health Questionnaire, Short-Form-12, Longitudinal Aging Study Amsterdam Physical Activity Questionnaire, loneliness, and social support questions.

RESULTS

The mean age of the participants in the study was 68.59 ± 6.72, and 53.2% were women. Based on the findings of pathway analysis, the most critical determinants of loneliness in older men and women were the number of children (total effect = -0.112, P = 0.006) and mood, respectively (total effect = 0.142, P < 0.001). According to results, older people with fewer children feel lonelier.

CONCLUSION

Compared with men, emotional loneliness is more common in older women. Older women, who lost their husbands, suffer from loneliness, mental health disorders, and low quality of life.

Mental health of homebound older adults in China

The mental health status of the homebound population in China is relatively overlooked. A sample of 1,301 older adults from Shandong Province was used to compare the mental health status among homebound, semi-homebound, and non-homebound older adults in China, and examine the moderation effects of loneliness and gender. This study found that, controlling for demographic and physical health status, the homebound population was more likely to have worse mental health status than non-homebound older adults. Experiencing loneliness intensified the adverse effects of being homebound on older adults' mental health. The negative effects of being semi-homebound on mental health were more pronounced among older males than females. Findings from this study suggested that homebound older adults in China experienced psychological challenges. Social programs and interventions may be designed to improve this population's mental health.

Multidimensional factors affecting homebound older adults: A systematic review

PURPOSE

To systematically identify the multidimensional factors affecting homebound older adults.

DESIGN

Systematic review.

METHODS

We searched PubMed, MEDLINE, Cochrane Library, CINAHL, EMBASE, and PsycINFO from inception to November 15, 2020. This systematic review followed the Preferred Reporting Items for Systematic Review and Meta-analysis guidelines. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment.

FINDINGS

Nineteen studies met the review criteria; the studies were either cross-sectional or longitudinal. Most studies have focused on personal factors affecting homebound older adults. The individual construct consisted of demographic, biological, psychological, functional, and health-related factors. The structural construct included architectural, environmental, community, and social factors. Based on the different definitions of homebound used in the studies, the prevalence of homebound status ranged from 3.5% to 39.8%.

CONCLUSIONS

The prevalence of homebound status among older adults varied depending on how homebound was defined. Homebound status is the interaction between the individual and structural constructs. Variations in cultural, political, and economic conditions could influence homebound status across countries over time. Comprehensive assessment and interventions for homebound older adults based on multidisciplinary approaches are recommended for nurses.

CLINICAL RELEVANCE

This research will impact the development of nursing strategies to screen homebound older adults and provide targeted preventive interventions so that older adults with many risk factors do not become homebound.

Monitoring Cognitive Health Status in Homebound Older Adults: Insights from a Nationwide Request for Information

The COVID-19 pandemic has fueled growing concerns about the long-term impacts on outcomes in older adults including social isolation and declines in cognitive health. Prior to the pandemic, the Administration for Community Living (ACL) released a nationwide request for information to understand how community-based organizations monitor changes in cognitive status for homebound older adults. This Perspective describes strategies reported by community-based organizations to monitor cognitive status in homebound older adults and notes the potential for technology to mitigate the risk of social isolation and delays in observing cognitive decline, considerations that are especially relevant during COVID-19 amid social distancing requirements.

Modifying Behavioral Activation to Reduce Social Isolation and Loneliness Among Older Adults

OBJECTIVE

To describe our modification of Behavioral Activation to address social isolation and loneliness: Brief Behavioral Activation for Improving Social Connectedness. Our recent randomized clinical trial demonstrated the effectiveness of the intervention, compared to friendly visit, in alleviating loneliness, reducing depressive symptoms, and increasing social connectedness with lonely homebound older adults receiving home-delivered meals.

METHODS

We modified Brief Behavioral Activation Treatment for Depression to address social isolation and loneliness by addressing each of its key elements: Psychoeducation; intervention rationale; exploration of life areas, values and activities; and activity monitoring and planning. The intervention consisted of six weekly sessions, up to 1 hour each. Interventionists were bachelor's-level individuals without formal clinical training who participated in an initial 1-day training as well as ongoing supervision by psychologists and social workers trained in BA throughout the study delivery period.

RESULTS

We provide three case examples of participants enrolled in our study and describe how the intervention was applied to each of them.

CONCLUSIONS

Our preliminary research suggests that Behavioral Activation modified to address social connectedness in homebound older adults improves both social isolation and loneliness. This intervention has potential for scalability in programs that already serve homebound older adults. Further research is needed to solidify the clinical evidence base, replicate training and supervision procedures, and demonstrate the sustainability of Brief Behavioral Activation for Improving Social Connectedness for homebound and other older adults.

Barriers and Facilitators to Social Participation in Older Adults: A Systematic Literature Review

Objectives: Social participation has been shown to improve health, well-being, and quality of life in older adults. Previous reviews on social participation have been limited to identifying logistical barriers. The current review sought to examine barriers of social participation more broadly, as well as potential facilitators.Methods: We conducted a systematic review to collate identified barriers and facilitators to social participation in older adults. Seventy-six studies were eligible for inclusion.Results: Four main themes of barriers and facilitators to social participation associated with aging emerged: Demographic factors (such as age and socioeconomic status), Individual/Internal factors (such as motivations and health), Environmental/Infrastructure (such as accessibility, transport, and neighborhood cohesion), and Social Networks (particularly preexisting network size).Conclusions: These findings extended previous reviews to show that personal motivations, preexisting social networks, and neighborhood cohesion play vital roles in improving and maintaining quality social participation. The ability to facilitate this can occur at the individual therapeutic level and at the community level.Clinical implications: The findings highlight the need to consider barriers beyond logistical issues. In particular, healthy aging initiatives may benefit from matching social activities with individual motivations, and preventive measures to establish social networks early in the aging process are important.

Receipt Of Home-Based Medical Care Among Older Beneficiaries Enrolled In Fee-For-Service Medicare

Millions of older Americans are homebound and may benefit from home-based medical care. We characterized the receipt of this care among community-dwelling, fee-for-service Medicare beneficiaries ages sixty-five and older surveyed in the National Health and Aging Trends Study between 2011 and 2017. Five percent of those surveyed received any home-based medical care between 2011 and 2017 (mean follow-up time per person was 3.4 years), and 75 percent of home-based medical care recipients were homebound. Only 11 percent of the total homebound population (approximately 4.4 million fee-for-service Medicare beneficiaries in 2017) received any home-based medical care between 2011 and 2017. Receipt of home-based medical care was more common among homebound beneficiaries living in metropolitan areas and assisted living facilities, which suggests that geographic factors create operational efficiencies for home-based medical care practices that may improve their financial sustainability within the fee-for-service reimbursement setting. The significant unmet needs of this high-need, high-cost population and the known health and cost benefits of home-based medical care should spur stakeholders to expand the availability of this care.

"Bai Lod" holistic health experienced by homebound older people in the southern Thai community

OBJECTIVES

This qualitative descriptive study aims to explore the meanings of holistic health in the southern Thai culture experienced by homebound older people.

BACKGROUND

The ageing society necessitates many services to meet the holistic needs of older people. Homebound older people are commonly an understudied population who may view their holistic health and well-being differently from others. Due to geographical differences and local Thai cultural context, exploring the holistic health in the southern Thai culture would help promote a healthy lifestyle and improve their health outcomes.

METHODS

Based on purposeful sampling, 16 key informants who were homebound older people (ages ≥ 60 years old) living at home in a rural southern Thai community were participated in semi-structured interviews. Informants consisted of six males and ten females who were Buddhist and married. Their ages ranged from 79 to 99, including nine homebound older people who lived in a couple, and seven widows and widowers. Eight had completed the primary school, and others were uneducated. The data were analysed with a content analysis.

RESULTS

Most of the informants had chronic diseases. In a broad main theme, the informants described the holistic health in local context as 'Bai Lod; which means being alive with positive, active and independent functioning. This theme included three sub-themes: self-supporting or taking care of themselves, having the ability to control their health conditions and being proud as a healthy older adult. The older people described self-supporting as the ability to perform their activities of daily living, take care of their own health and work independently (active living). Having the ability to control their health conditions meant functioning well physically, although being frail, by maintaining their health through self-management, and having a good mental health during such a life-changing situation. Older people valued the ability to live by themselves without being a burden to their family. They felt happy with their life.

CONCLUSION

Holistic health was described as being positive and active at home, and influenced by beliefs and values related to good physical function, mental health and spiritual activities. These findings could help healthcare professionals better understand older people' health, well-being and cultural care in order to develop alternative strategies to maintain, enhance and support an active life for homebound older people.

Population-Based Screening for Functional Disability in Older Adults

BACKGROUND AND OBJECTIVES

Screening for functional disability is a promising strategy to identify high-need older adults. We compare 2 disability measures, activities of daily living (ADLs), and life space constriction (LSC), in predicting hospitalization and mortality in older adults.

RESEARCH DESIGN AND METHODS

We used the nationally representative National Health and Aging Trends Study of 30,885 observations of adults aged 65 years and older. Outcomes were 1-year mortality and hospitalization. Predictors were ADLs (receiving help with bathing, eating, dressing, toileting, getting out of bed, walking inside) and LSC (frequency of leaving home).

RESULTS

Of respondents, 12.4% reported 3 or more ADLs and 10.8% reported rarely/never leaving home. ADL disability and LSC predicted high rates of 1-year mortality and hospitalization: of those with 3 or more ADLs, 46.4% died and 41.0% were hospitalized; of those who never/rarely left home, 40.7% died and 37.0% were hospitalized. Of those with both 3 or more ADLs and who never/rarely left home, 58.4% died. ADL and LSC disability combined was more predictive of 1-year mortality and hospitalization than either measure alone. ADL disability and LSC screens identified overlapping but distinct populations. LSC identified more women (72.6% vs 63.8% with ADL disability), more people who live alone (40.7% vs 30.7%), fewer who were White (71.7% vs 76.2%) with cancer (27.6% vs 32.4), and reported pain (67.1% vs 70.0%).

DISCUSSION AND IMPLICATIONS

LSC and ADLs both independently predicted mortality and hospitalization but using both screens was most predictive. Routine screening for ADLs and LSC could help health systems identify those at high risk for mortality and health care use.

The Association Between Income and Incident Homebound Status Among Older Medicare Beneficiaries

IMPORTANCE

A large and growing population of older adults with multimorbidity, cognitive impairment, and functional disability live in the community, but many never or rarely leave their homes. Being homebound is associated with decreased access to medical services, poor health outcomes, and increased mortality. Yet, it is unknown what factors, in particular socioeconomic factors, are associated with new onset of homebound status.

OBJECTIVE

To evaluate the association between income and risk of becoming homebound.

DESIGN

Observational cohort study using 2011 to 2018 data from the National Health and Aging Trends Study, a nationally representative sample of Medicare beneficiaries aged 65 years and older.

SETTING

Population-based study in the United States.

PARTICIPANTS

A total of 7,042 initially nonhomebound community-dwelling older adults.

EXPOSURE

Total annual household income at baseline (in 2011) measured via self-report.

OUTCOME

Annual measure of homebound status, defined as leaving home an average of 1 d/wk or less.

RESULTS

Over 7 years, 15.81% of older adults in the lowest income quartile (≤$15,003) became homebound, compared with only 4.64% of those in the highest income quartile (>$60,000). In a competing risks analysis accounting for risks of death and nursing home admission, and adjusted for clinical and demographic characteristics, those in the lowest income quartile had a substantially higher subhazard of becoming homebound than those in the highest income quartile (1.65; 95% confidence interval = 1.20-2.29). Moreover, we see evidence of a gradient in risk of homebound status by income quartile.

CONCLUSION AND RELEVANCE

Our work demonstrates that financial resources shape the risk of becoming homebound, which is associated with negative health consequences. In the context of existing income disparities, more support is needed to assist older adults with limited financial resources who wish to remain in the community.

Friendship-related social isolation is a potential risk factor for the transition from robust to prefrailty among healthy older adults: a 1-year follow-up study

PURPOSE

Social factors are often overlooked when considering physical frailty. The purpose of this study was to determine whether social isolation is associated with new onset of physical frailty among healthy Japanese older adults.

METHODS

This was a 1-year prospective cohort study conducted in Japan from August 2014 to August 2015. The participants were 229 Japanese older people (106 men, 123 women, mean age = 69.3 ± 4.2 years) who did not have prefrailty or frailty at baseline and who were current students or graduates of a community college for older people in Japan. Social isolation was assessed using the Lubben Social Network Scale-6 in terms of overall social isolation, family-related social isolation, and friendship-related social isolation. Frailty was categorized using the Fried frailty criteria. The association between new onset of physical frailty and baseline characteristics, including social isolation, was investigated.

RESULTS

At 1-year follow-up, 180 (78.6%) of the participants remained robust, while 49 (21.4%) were identified as prefrail; no participants were identified as frail. Prefrailty was only associated with friendship-related social isolation (odds ratio: 4.58, 95% confidence interval 2.11-9.92, P < 0.001) at baseline. No significant associations were observed for any other baseline characteristics, including overall social isolation, family-related social isolation, comorbidities, body composition, and physical function.

CONCLUSION

Older adults with friendship-related social isolation are four times more likely to develop prefrailty from robust during the 1-year follow-up. The results suggest that friendship-related social isolation increases the risk of healthy older adults transitioning from robust to prefrail.

Increasing Life-Space Mobility in Community-Dwelling Older Persons With Cognitive Impairment Following Rehabilitation: A Randomized Controlled Trial

BACKGROUND

Community-dwelling older persons with cognitive impairment (CI) following discharge from geriatric rehabilitation are at high risk of losing life-space mobility (LSM). Interventions to improve their LSM are, however, still lacking. The aim of this study was to evaluate the effects of a CI-specific, home-based physical training and activity promotion program on LSM.

METHODS

Older persons with mild-to-moderate CI (Mini-Mental State Examination: 17-26 points) discharged home from rehabilitation were included in this double-blinded, randomized, placebo-controlled trial with a 12-week intervention period and 12-week follow-up period. The intervention group received a CI-specific, home-based strength, balance, and walking training supported by tailored motivational strategies. The control group received a placebo activity. LSM was evaluated by the Life-Space Assessment in Persons with Cognitive Impairment, including a composite score for LSM and 3 subscores for maximal, equipment-assisted, and independent life space. Mixed-model repeated-measures analyses were used.

RESULTS

One hundred eighteen participants (82.3 ± 6.0 years) with CI (Mini-Mental State Examination: 23.3 ± 2.4) were randomized. After the intervention, the home-based training program resulted in a significant benefit in the Life-Space Assessment in Persons with Cognitive Impairment composite scores (b = 8.15; 95% confidence interval: 2.89-13.41; p = .003) and independent life-space subscores (b = 0.39; 95% confidence interval: 0.00-0.78; p = .048) in the intervention group (n = 63) compared to control group (n = 55). Other subscores and follow-up results were not significantly different.

CONCLUSIONS

The home-based training program improved LSM and independent life space significantly in this vulnerable population. Effects were not sustained over the follow-up. The program may represent a model for improved transition from rehabilitation to the community to prevent high risk of LSM restriction.

Natural History of Social Participation in the Very Old: Findings from the Newcastle 85+ Study

Objective: To describe the natural history of social participation in people aged 85 years and over. Methods: Prospective cohort study; Newcastle 85+ study. Data were collected at baseline (n = 850) and at 18-, 36- and 60-month follow-ups (n = 344). Participation in 19 social activities (e.g. playing bingo, doing volunteer work and watching television) was measured at each time point. Results: The mean number of activities reported at baseline was 8.7 (SD 2.6). The number of activities was higher in those with higher educational attainment and intact walking ability (both p < .001). Social participation decreased significantly over time (p < .001) and at a similar rate in both sexes and for those with/without limited walking ability but at a higher rate in those with higher than lower educational attainment (p = .019). Discussion: Social participation seems to decrease significantly between ages 85 and 90 years; ways of encouraging social participation in this age group are needed.

Improving Social Connectedness for Homebound Older Adults: Randomized Controlled Trial of Tele-Delivered Behavioral Activation Versus Tele-Delivered Friendly Visits

OBJECTIVE

To test the acceptability and effectiveness of a lay-coach-facilitated, videoconferenced, short-term behavioral activation (Tele-BA) intervention for improving social connectedness among homebound older adults.

METHODS

We employed a two-site, participant-randomized controlled trial with 89 older adults (averaging 74 years old) who were recipients of, and initially screened by, home-delivered meals programs. All participants reported loneliness; many reported being socially isolated and/or dissatisfaction with social support. Participants received five weekly videoconference sessions of either Tele-BA or Tele-FV (friendly visits; active control). Three primary outcomes were social interaction (Duke Social Support Index [DSSI] Social Interaction Subscale), subjective loneliness (PROMIS Social Isolation Scale), and DSSI Satisfaction with Social Support Subscale. Depression severity (PHQ-9) and disability (WHODAS 2.0) were secondary outcomes. Mixed-effects regression models were fit to evaluate outcomes at 6- and 12-weeks follow-up.

RESULTS

Compared to Tele-FV participants, Tele-BA participants had greater increase in social interaction (t [81] = 2.42, p = 0.018) and satisfaction with social support (t [82] = 2.00, p = 0.049) and decrease in loneliness (t [81] = -3.08, p = 0.003), depression (t [82] = -3.46, p = 0.001), and disability (t [81] = -2.29, p = 0.025).

CONCLUSION

A short-term, lay-coach-facilitated Tele-BA is a promising intervention for the growing numbers of homebound older adults lacking social connectedness. The intervention holds promise for scalability in programs that already serve homebound older adults. More research is needed to solidify the clinical evidence base, cost-effectiveness and sustainability of Tele-BA delivered by lay coaches for homebound and other older adults.

Trajectories of social resource use among informal lung cancer caregivers

BACKGROUND

Social support is a key component in maintaining cancer caregiver well-being, and many resources exist to facilitate caregivers' use of social support (eg, cancer support groups). This study sought to determine how informal cancer caregivers use social resources over the course of caregiving.

METHODS

The data are from the Comprehensive Health Enhancement Support System study of informal caregivers (n = 202) of patients with recently diagnosed lung cancer. Caregivers self-reported their sociodemographic and caregiving characteristics and social resource use over 6 months. Generalized additive models were used to assess social resource use over time, and generalized estimating equation logistic regression models were used to assess the correlates of social resource use.

RESULTS

Nearly two-thirds of caregivers reported any social resource use. The most prevalent social resources were faith-based groups (38%) and social clubs (30%). Only 1 in 4 caregivers participated in a formal resource such as counseling (11%) or a cancer support group (6%). Social resource use was lowest immediately after the diagnosis and increased over time. Formal resource use exhibited a nonlinear association with time such that formal resource use peaked approximately 9 to 10 months after the cancer diagnosis. Caregivers were more likely to report social resource use if the patient also reported social engagement.

CONCLUSIONS

This study has found that many cancer caregivers do not use social resources, although social resource use increases over time after the cancer diagnosis. Because of the association between social engagement and well-being, this information may inform future research and interventions to improve outcomes for cancer caregivers and their families.

Measuring Social Participation in the Health and Retirement Study

BACKGROUND AND OBJECTIVES

Large data sets have the potential to reveal useful information regarding social participation; however, most data sets measure social participation via individual items without a global assessment of social participation.

RESEARCH DESIGN AND METHODS

We used data from the Health and Retirement Study (HRS) to assess whether 8 items from questionnaire pertaining to social participation (religious attendance, caring for an adult, activities with grandchildren, volunteering, charity work, education, social clubs, nonreligious organizations) formed a reliable, cohesive scale and to explore the predictive validity of this scale. We included respondents 65 years and older in the HRS who returned the psychosocial questionnaire in 2010 and 2012 with responses to the social participation items (n = 4,317 and n = 3,978). Three scales were explored: SoPart-30 using the original scoring; SoPart-10 using modified scoring; and SoPart-5 using dichotomous scoring.

RESULTS

Five items were retained as a single factor for each scale, and graded response models and Mokken scale analysis confirmed the scale items with the SoPart-10 scale having the highest reliability (alpha = 0.74).

DISCUSSION AND IMPLICATIONS

Results suggest that a scale derived from the social participation items in the HRS may be useful in characterizing general social participation levels and identifying modifiable factors that can promote it in older populations.

Impact of Savoring Ability on the Relationship Between Older Adults’ Activity Engagement and Well-Being

The relationship between activity engagement and well-being can vary based on individual characteristics, and it is important to identify moderating factors to support the development and implementation of aging services. The current study examined whether the relationship between activity engagement and well-being depends on older adults’ savoring ability, that is, the ability to attend to positive experiences and to engage in emotion regulation strategies to enhance positive feelings during those experiences. A total of 5,128 older adults ( Mage = 83.86 years) completed measures of activity engagement, savoring, and well-being (i.e., life satisfaction, depression, loneliness, purpose, and health). Multilevel modeling analyses revealed that activity engagement and savoring independently predicted better functioning across all well-being measures. However, savoring moderated the relationship between activity engagement and four well-being measures (life satisfaction, depression, loneliness, and purpose). Findings suggest that older adults with low activity engagement may particularly benefit from savoring-skills training to enhance their psychological well-being.

Cut-off for the Life-Space Assessment in persons with cognitive impairment

BACKGROUND

A version of the Life-Space Assessment in persons with cognitive impairment (LSA-CI) has recently been developed.

AIMS

To establish a cut-off value for the newly developed Life-Space Assessment in persons with cognitive impairment (LSA-CI).

METHODS

In a cross-sectional study including 118 multimorbid, older persons with cognitive impairment, life-space mobility (LSM) was documented by the LSA-CI. The analysis was rationalized by Global Positioning System (GPS)-based measures of spatial distance from home. A receiver-operating characteristic (ROC) curve was created and the cut-off point for the LSA-CI was identified with the Youden's Index.

RESULTS

ROC curve analysis indicated a critical value of 26.75 (within a range of 0-90) to differentiate between low and high LSM with a sensitivity of 78.1% and specificity of 84.2%.

DISCUSSION

Diagnostic interpretation of the ROC curves revealed that low and high LSM groups can be differentiated with the proposed cut-off.

CONCLUSIONS

The proposed LSA-CI cut-off score can be recommended to tailor clinical interventions and evaluate change over time.

Going Online to Stay Connected: Online Social Participation Buffers the Relationship Between Pain and Depression

OBJECTIVES

Maintaining offline social participation (i.e., face-to-face social interaction) is key for healthy aging, but older adults who experience pain tend to restrict their social activity outside of the home. The onset of pain may set off a downward spiral where lowered social participation increases the risk of depression and vice versa. This study thus assesses whether online social participation (i.e., the use of online social network sites) moderates the effect of pain on depression, possibly functioning as a compensatory mechanism for reduced offline social participation for those in pain.

METHOD

Logistic regression models with a lagged dependent variable were used with panel data from the National Health and Aging Trends Study. An interaction term was included to assess the moderating effect of online social participation.

RESULTS

We find that online social participation buffers the detrimental effect of pain on depression. However, the effect of pain on online social participation was not statistically significant.

DISCUSSION

Findings show that online social participation can alleviate the negative effects of pain on mental well-being, and suggest that online social participation can supplement attempts to maintain offline social participation in later life, especially for those whose social activity may be limited by pain.

Homebound Status and the Critical Role of Caregiving Support

The homebound population relies on both paid and family caregivers to meet their complex care needs. In order to examine the association between intensity of caregiving support and leaving the home, we identified a population of community-dwelling, homebound Medicare beneficiaries age ≥65 (n = 1,852) enrolled in the 2015 National Health and Aging Trends Study and measured the support they received from paid and family caregivers. Those who had ≥20 h of caregiving support per week had 50% less odds of being "exclusively homebound" (rarely or never leave home) (OR 0.56, p < .01). Policies that facilitate increased support for family caregivers and better access to paid caregivers may allow homebound individuals who would otherwise be isolated at home to utilize existing community-based long-term care services and supports.

Valued activities among individuals with and without functional impairments: Findings from the National Health and Aging Trends study (NHATS)

Using the National Health and Aging Trends Study (NHATS), we examined baseline activity and functional status. Respondents were classified as High (n=1,662), Moderate (n=1,973), or Low (n=989) Function and rated importance of and actual participation in four activities. Transportation and health were also examined. Individuals classified as low function were less likely to engage in valued activities and more likely to report that poor health and transportation limited participation, compared to individuals with no or moderate functional impairments. Data suggest the importance of developing interventions which bridge the gap between activity preferences and participation for older adults with functional limitations.

Life-space mobility in older persons with cognitive impairment after discharge from geriatric rehabilitation

OBJECTIVES

To describe life-space mobility and identify its determinants in older persons with cognitive impairment after discharge from geriatric rehabilitation.

METHODS

A cross-sectional study in older community-dwelling persons with mild to moderate cognitive impairment (Mini-Mental State Examination, MMSE: 17-26) following geriatric rehabilitation was conducted. Life-space mobility (LSM) was evaluated by the Life-Space Assessment in Persons with Cognitive Impairment (LSA-CI). Bivariate analyses and multivariate regression analyses were used to investigate associations between LSM and physical, cognitive, psychosocial, environmental, financial and demographic characteristics, and physical activity behavior.

RESULTS

LSM in 118 older, multimorbid participants (age: 82.3 ± 6.0 years) with cognitive impairment (MMSE score: 23.3 ± 2.4 points) was substantially limited, depending on availability of personal support and equipment. More than 30% of participants were confined to the neighborhood and half of all patients could not leave the bedroom without equipment or assistance. Motor performance, social activities, physical activity, and gender were identified as independent determinants of LSM and explained 42.4% (adjusted R²) of the LSA-CI variance in the regression model.

CONCLUSION

The study documents the highly restricted LSM in older persons with CI following geriatric rehabilitation. The identified modifiable determinants of LSM show potential for future interventions to increase LSM in such a vulnerable population at high risk for restrictions in LSM by targeting motor performance, social activities, and physical activity. A gender-specific approach may help to address more advanced restrictions in women.

Health promoting lifestyles and influencing factors among empty nesters and non-empty nesters in Taiyuan, China: a cross-sectional study

Background

In China, the problems of population aging and empty nesting have become important issues which will affect the social stability and economic development. The aim of this study was to explore the health promoting lifestyles and influencing factors among empty nesters and compare with non-empty nesters to find out their differences, so as to provide a scientific evidence for people to formulate health management strategies for elderly.

Methods

A cross-sectional survey which used a stratified random cluster sampling method, was conducted among 500 elders in six districts of Taiyuan, China, there were 288 empty nesters and 212 non-empty nesters. The general information and health- promoting lifestyles were investigated by using the self-made General Information Questionnaire and Health Promoting Lifestyle Scale(HPLP). Two-sample t-test and Chi-square test were used to compare the sociodemographic factors, HPLP scores of empty nesters to non-empty nesters; Multiple stepwise linear regression was performed to estimate influencing factors related to the HPLP of empty nesters and non-empty nesters.

Results

The current findings showed that there were differences between the empty nesters and non-empty nesters in gender, resident, marital status, education and income, self-care ability, source of income, relationship with spouse and social activities (P < 0.05). Empty nesters were mostly male, married, had a higher education level, self-care ability and income and lived in urban compared with non-empty nesters. The health promoting lifestyles of the elderly in this survey were in the medium level, the highest score for all dimensions in both groups was in nutrition, whereas health responsibility was executed worst. The HPLP and six subscales scores of the empty nesters were higher than non-empty nesters, there were significant differences in total score of HPLP, self-realization and health responsibility (P < 0.01). Multiple regression analysis showed that the main predictive factors for the empty nesters were education, self-care ability and resident, whereas the main predictive factors for the non-empty nesters were parents-child relationship, source of income and age; social activity was the common factor for two group.

Conclusion

The health promoting lifestyles of the empty nesters was better than that of the non-empty nesters. Health responsibility, interpersonal relations and stress management were key dimensions to be improved. Except social activity, education, self-care ability and resident were the unique influencing factors of health-promoting lifestyles for empty nesters, while the parents-child relationship, income and age were unique factors for non-empty nesters. The main target of Intervention strategy for elderly health promoting lifestyles should be the enhance of health responsibility, interpersonal relations and stress management by improving social activities, parent-child relationship, education and income of elderly.
