The epidemiology of social isolation and loneliness among older adults during the last years of life

Association of social isolation and loneliness with incident rheumatoid arthritis in a population-based cohort study

OBJECTIVE

This study endeavors to reveal the link between social isolation, loneliness, and the incidence of rheumatoid arthritis (RA) and to explore whether genetic factors may receive interference.

METHODS

A prospective cohort study supported by the UK Biobank database. Social isolation and loneliness were considered major exposures, which were captured through self-report questionnaires. The primary endpoint was incident RA. Multivariable Cox proportional hazard regression was utilized to explore the connection between social isolation and loneliness and RA events. Conjoint and interaction analyses were conducted to determine whether social independence and loneliness were independent predictors of RA. Additional sensitivity analyses and subgroup analyses were carried out to evaluate the stability of the results.

RESULTS

A total of 3949 RA cases were documented during a median follow-up of 12.39 years eventually among the 345,324 subjects. Social isolation (Moderately isolated: HR: 1.080, 95 % CI: 1.009-1.156; most isolated: HR: 1.121, 95 % CI: 1.018-1.234) was markedly related to an increased risk of RA, and these associations were not modified by genetic risk for RA. Cumulative risk map results observed that social isolation and loneliness and their subcomponents increase the cumulative incidence of RA over time.

CONCLUSION

Social isolation is independently associated with an enhanced prevalence of RA, and the correlation remained significant after accounting for genetic susceptibility to RA. Further exploration of the association between social isolation and RA may help to refine the etiology of RA and provide scientific evidence for primary health care of RA.

The Prevalence of Social Isolation and Loneliness Among Older Adults Residing in Rural Utah Communities

An estimated 24% of community-dwelling older adults experience social isolation defined as infrequent social contact or having few social relationships, and 35% of adults aged >45 report being lonely, a subjective feeling of isolation or lack of social contact. Social isolation and loneliness are associated with poor physical and mental health. The purpose of our study was to assess the prevalence of social isolation and loneliness among older adults receiving home health services in rural Utah communities. We conducted a cross-sectional study with 41 persons at the onset of enrollment in home care services in 2 rural counties in Utah. We assessed loneliness, social support and quality of life using validated surveys. We conducted descriptive statistics to describe the participants demographics and Pearson's Correlation Coefficients to assess a relationship between loneliness and quality of life and satisfaction with health. Participants were predominately older, with an average age of 75.6 years (range 59-93 years.) The majority of participants were female 27 (65.8%) and identified as White 36 (87.8%). Overall, the average loneliness score was 1.51 (0.67 SD) indicating the prevalence of loneliness was low among our study population. We found statistically significant correlation among participants who rated their loneliness higher with lower rates of satisfaction with their health and overall quality of life. Future research is needed with larger sample sizes to validate our findings which may inform policy changes including standardizing assessment of social isolation and loneliness and offering person-centered interventions to prevent the physical and psychological consequences of social isolation.

Addictive behaviors in older adults: The role of psychopathological symptoms, health, purpose in life, and loneliness

BACKGROUND AND OBJETIVES

This study explored addictive behaviors, including both substance use and behavioral addictions. Specifically, we examined the predictive role of psychopathological symptoms, health, loneliness, and purpose in life in addictive behaviors, as well as analyzing gender differences in the variables studied.

METHOD

The sample comprises 100 individuals over 60 (Mage=69.1; SD=6.7; 52% men). Multiple linear regression analyses were conducted to examine predictors of addictive behaviors, and t-tests to analyze gender differences.

RESULTS

Psychopathological symptoms were identified as a risk factor for problematic alcohol and substance use (β between -.392 and .877). Additionally, psychopathological symptoms (β between .314 and .432) and mental health were both significant predictors of compulsive buying (β=-.579). Women exhibited higher scores in psychopathological symptoms (p≤.015), while men showed higher levels of physical and mental health (p≤.022).

CONCLUSION

Understanding the risk factors associated with addictive behaviors in older adults is crucial to increasing public awareness of these problems and to improving early detection and effective management of addictions in this demographic group.

PrEP-eligible behaviours and condom use among sexually active older adults in China: Findings from the sexual well-being (SWELL) study

OBJECTIVES

Older adults remain sexually active and at risk of sexually transmitted infections (STIs). This study aimed to explore consistent condom use and pre-exposure prophylaxis (PrEP)-eligible behaviours and their correlates among sexually active older adults in China.

STUDY DESIGN

Cross-sectional study.

METHODS

Data were collected from a multicentre cross-sectional survey in China between June 2020 and December 2022. Eligibility criteria were community-dwelling older adults aged ≥50 years who were sexually active (i.e. had oral, vaginal or anal sex in the past year). In-person questionnaire interviews included demographic characteristics, general health and sexual health information.

RESULTS

In total, 1332 sexually active older adults were recruited in the study. Overall, 33.7 % (449/1332) of participants consistently used a condom in the past year and 7.9 % (105/1332) reported PrEP-eligible behaviours. Consistent condom use was significantly associated with the following characteristics: age (only for women aged 50-59 years [adjusted odds ratio (aOR) 0.60, 95 % confidence interval (CI): 0.36-0.98]; women aged 60-69 years [aOR 0.27, 95 % CI: 0.10-0.71]), living alone (men [aOR 0.40, 95 % CI: 0.20-0.79]; women [aOR 0.27, 95 % CI: 0.10-0.72]), body mass index (men [aOR 1.59, 95 % CI: 1.18-2.14]; women [aOR 1.76, 95 % CI: 1.13-2.73]), general health status (men reporting 'fair' health [aOR 0.62, 95 % CI: 0.39-0.97]; women reporting 'very good' health [aOR 0.39, 95 % CI: 0.16-0.96]), talking about sex (men [aOR 1.67, 95 % CI: 1.23-2.26]) and knowledge of condom use to prevent sexually transmitted infections (men [aOR 1.52, 95 % CI: 1.06-2.18]). PrEP-eligible behaviours were more likely in men (aOR 1.76, 95 % CI: 1.08-2.90) and in individuals who were not in a stable relationship (aOR 4.80, 95 % CI: 2.41-9.54) and who lived alone (aOR 2.02, 95 % CI: 1.07-3.82).

CONCLUSION

Consistent condom use was moderate among sexually active older adults in China. More than one-quarter of older adults who lived alone reported PrEP-eligible behaviours. Comprehensive intervention measures should consider the characteristics and health needs of community-dwelling older adults.

The Potential of a Robot Presence in Close Relationship to Influence Human Responses to Experimental Pain

Pain management is a critical challenge in healthcare, often exacerbated by loneliness and emotional distress. This study investigated the potential of a communication robot, Moffuly, to reduce pain perception and influence hormonal responses in a controlled experimental setting. Nineteen healthy participants underwent heat pain stimulation under two conditions: with and without robotic interaction. Pain levels were assessed using the Short-form McGill Pain Questionnaire and the Visual Analogue Scale, while mood and mental states were evaluated through established questionnaires including the Profile of Mood States, Hospital Anxiety and Depression Scale, and Self-Rating Depression Scale. Hormonal changes, including cortisol, growth hormone, oxytocin, estradiol, and dehydroepiandrosterone-sulfate, were measured from blood samples collected at key time points. The results demonstrated significant reductions in subjective pain and improvements in mood following robotic interaction. These effects were accompanied by favorable hormonal changes, including increased oxytocin and decreased cortisol and growth hormone levels. The findings suggest that robotic interaction may serve as an innovative approach to pain management by addressing both physiological and psychological factors. This study highlights the potential of robotics to complement traditional therapies in alleviating pain and enhancing emotional well-being. By mitigating emotional distress and loneliness, robotic interventions may enhance existing pain therapies and offer innovative solutions for resource-limited healthcare systems.

How do older adults react to social robots' offspring-like voices

Social robots are being developed as a technological solution to alleviate older adults' loneliness due to separation from their offspring. This study explores how and why offspring-like voices affect older adults' acceptance of social robots from an auditory perspective, which differ from the visual aspects of human-robot interactions. Three scenario-based studies are conducted among a large number of cognitively intact older adults. Our findings reveal a positive correlation between the offspring-like voices of social robots and older adults' acceptance of the robots. Further, social identity served as a psychological mechanism mediating the effect of offspring-like voices on the acceptance of older adults, whereas spatial distance acted as a positive moderator of these direct and indirect effects. Notably, older adults were more willing to accept social robots with grandchildren-like voices. These insights offer theoretical contributions to the literature on social identity theory and the similarity attraction paradigm, as well as practical implications for social robot design and development, thereby contributing to the evolving landscape of human-robot interaction acceptance.

The prevalence of lifetime trauma and association with physical and psychosocial health among adults at the end of life

BACKGROUND

National guidelines recognize lifetime trauma as relevant to clinical care for adults nearing the end of life. We determined the prevalence of early life and cumulative trauma among persons at the end of life by gender and birth cohort, and the association of lifetime trauma with end-of-life physical, mental, and social well-being.

METHODS

We used nationally representative Health and Retirement Study data (2006-2020), including adults age > 50 who died while enrolled (N = 6495). Early life and cumulative traumatic events were measured using an 11-item traumatic events scale (cumulative trauma: 0-5+ events over the lifespan). We included six birth cohorts (born <1924; children of depression [1924-1930]; HRS cohort [1931-1941]; war babies [1942-1947]; early baby-boomers [1948-1953]; mid-baby boomers [1954-1959]). End-of-life outcomes included validated measures of physical (pain, fatigue, dyspnea), mental (depression, life satisfaction), and social (loneliness, social isolation) needs. We report the prevalence of lifetime trauma by gender and birth cohort and the adjusted probability of each end-of-life outcome by trauma using multivariable logistic regression.

RESULTS

The mean age at death was 78 years (SD = 11.1) and 52% were female. Lifetime trauma was common (0 events: 19%; 1-2: 47%; 3-4: 25%; 5+: 9%), with variation in individual events (e.g., death of a child, weapons in combat) by gender and birth cohort. After adjustment, increasing cumulative trauma was significantly associated (p-value<0.001) with higher reports of end-of-life moderate-to-severe pain (0 events: 46%; 1-2 events: 50%; 3-4 events: 57%; 5+ events: 60%), fatigue (58%; 60%; 66%; 69%), dyspnea (46%; 51%; 56%; 58%), depression (24%; 33%; 37%; 40%), loneliness (12%; 17%; 19%; 22%), and lower life satisfaction (73%; 63%; 58%; 54%).

CONCLUSION

Older adults in the last years of life report a high prevalence of lifetime traumatic events which are associated with worse end-of-life physical and psychosocial health. A trauma-informed approach to end-of-life care and management of physical and psychosocial needs may improve a patient's quality of life.

The Long-Lasting Effect of Multidisciplinary Interventions for Emotional and Social Loneliness in Older Community-Dwelling Individuals: A Systematic Review

BACKGROUND

Loneliness can occur at any age, but it is more prevalent among older adults due to the associated risk factors. Various interventions exist to improve this situation, but little is known about their long-term effects. Our aims were to determine if these interventions have long-lasting effects and for how long they can be sustained. Additionally, we aimed to analyze if the interventions carried out by volunteers affected the outcomes regarding loneliness and psychological impact.

METHODS

A systematic review was performed by searching the literature in the MEDLINE PubMed, SCOPUS, Web of Science, PsycINFO, and Web of Science databases for interventions focused on the lonely population. The inclusion criteria for this review were the assessment of loneliness using a validated tool, and loneliness being the primary or secondary outcome. The CASPe checklist was used to assess the risk of bias in the selected studies, and the PRISMA-ScR recommendations were followed to present and synthesize the results.

RESULTS

Thirty articles were included. The interventions identified were classified into five categories: psychosocial, technological, health promotion, physical exercise, and multicomponent interventions. Loneliness improved in 24 studies during the post-intervention analysis. Social connectivity and depressive symptoms also improved in most interventions. Long-term follow-ups were conducted with positive results in a total of 16 interventions. Depressive symptoms and social connectivity were also improved. Eight of the interventions were carried out by volunteers and showed good results regarding loneliness.

CONCLUSIONS

The results obtained in this work suggested that multidisciplinary interventions can reduce loneliness, but more controlled clinical studies are needed.

Medical-Legal Partnerships and Prevention: Caring for Unrepresented Patients Through Early Identification and Intervention

Caring for unrepresented patients encompasses legal, ethical, and moral challenges regarding decision-making, consent, the patient's values, wishes, best interest, and the healthcare team's professional integrity and autonomy. In this article, I consider the impact of the aging population and the effects of the social determinants of health and suggest that without preventive intervention, the number of unrepresented patients will continue to increase. The health, social, and legal risk factors for becoming unrepresented require a multidisciplinary response. Medical-Legal Partnerships (MLPs) bring healthcare and legal professionals together to address risk factors and health-harming legal needs. The article discusses the role of MLPs in identifying at-risk individuals, providing preventive interventions, and providing support. I make recommendations and conclude that proactive MLPs offer a sustainable approach to the ethical challenges in caring for unrepresented patients by providing interventions to prevent individuals from becoming unrepresented.

Race/Ethnicity, Nativity, and Gender Disparities in Mental Health Trajectories from Mid- to Later-Life: A Life Course-Intersectional Approach

BACKGROUND

Numerous studies have highlighted mental health disparities based on race/ethnicity, nativity, and gender across different life stages. However, few have investigated how the intersectionality of these factors influences mental health trajectories during midlife to late life. This study fills this gap by adopting a life course-intersectional approach, viewing mental health trajectories as dynamic processes shaped by the combined influences of race/ethnicity, nativity, and gender. It explores social, psychological, and physiological pathways contributing to these disparities.

DESIGN

Using data from the Health and Retirement Study (2006-2018; N = 38,049 observations) and growth curve models, this study examines how intra-individual trends in depressive symptoms (measured as CES-D scale, 07) are influenced by the intersection of race/ethnicity, nativity, and gender. It also investigates the impact of objective and subjective social isolation and physical health on group disparities in mental health trajectories.

RESULTS

The findings reveal that, during mid- to early late-life, most Black and Hispanic Americans experience higher levels of depressive symptoms compared to their White counterparts (disparities ranging from 0.184 to 0.463 for men and 0.117 to 0.439 for women). However, this disadvantage diminishes for US-born Hispanic men and US-born Black women (0.014-0.031 faster decrease rates compared to US-born White), while it intensifies for Hispanic immigrants (0.017-0.018 slower decrease rates compared to US-born White) in advanced ages. Mediation analysis demonstrates that both social isolation and physical health contribute to these disparities, with physical health explaining a larger portion, particularly in differences between immigrant Hispanic women and US-born Whites.

CONCLUSION

This study underscores the importance of a life course-intersectional approach in understanding mental health disparities. It emphasizes the need for improved social welfare systems and community-level interventions targeting the specific challenges faced by older Hispanic immigrants, especially women who encounter multiple forms of oppression.

The relationship between social relationships and sleep quality in older adults: Loneliness as a mediator and cognitive status as a moderator

OBJECTIVES

This study investigates the complex relationships among social support, social strain, loneliness, cognitive status, and sleep quality in adults aged 51 and above. It aims to explore loneliness as a mediator between social support, social strain, and sleep quality and to examine if, and how, the mediating effect differs by cognitive status.

METHODS

Eight years of data from the University of Michigan Health and Retirement Study were analyzed using a cross-lagged panel model. Moderated mediation analyses examined loneliness's mediating effect and cognitive status's moderating influence on the associations among social support, social strain, and sleep quality.

RESULTS

Loneliness mediated the relationships between social support, social strain, and sleep quality. Individuals with better cognitive function experienced an increased influence of social support on sleep quality by mitigating loneliness.

CONCLUSION

Considering the moderating role of cognitive status, sleep interventions individualized and tailored to these differences become essential.

The temporal sequence and reciprocal relationships of frailty, social isolation and loneliness in older adults across 21 years

BACKGROUND

It is unclear whether social isolation and loneliness may precede frailty status or whether frailty may precipitate social isolation and loneliness. We investigated the reciprocal and temporal sequence of social isolation, loneliness, and frailty among older adults across 21 years.

METHODS

We used seven waves of the Longitudinal Aging Study Amsterdam from 2302 Dutch older adults (M = 72.6 years, SD = 8.6, 52.1% female) ages 55 or older. Using random intercept cross-lagged panel models, we investigated between- and within-person associations of social isolation and loneliness with frailty. Frailty was measured using the Frailty Index. Loneliness was measured using the 11-item De Jong Gierveld Loneliness Scale. Social isolation was measured using a multi-domain 6-item scale.

RESULTS

Social isolation and loneliness were weakly correlated across waves. At the between-person level, individuals with higher levels of frailty tended to have higher levels of social isolation but not loneliness. At the within-person level, the cross-lagged paths indicated that earlier frailty status predicted future social isolation and loneliness over time. However, prior social isolation was not associated with subsequent frailty except at time point 5 (T5). Loneliness at specific time points (T1, T4 and T6) predicted greater frailty at later time points (T2, T5 and T7). The results also supported reciprocal and contemporaneous relations between social isolation, loneliness and frailty.

CONCLUSIONS

Social isolation and loneliness are potential outcomes of frailty. Public health policies and health practitioners should prioritise interventions targeting social connection among older adults with pre-frailty or frailty.

Prevalence of Unwanted Loneliness and Associated Factors in People over 65 Years of Age in a Health Area of the Region of Murcia, Spain: HELPeN Project

Background/Objectives: Population aging poses many challenges to public health, highlighting loneliness and social isolation as severe problems that affect the physical and mental health of older adults. During the COVID-19 pandemic, these became aggravated. The objective of the present study was to assess the prevalence of loneliness and its relationship with social isolation, depression, cognitive deterioration, sleep quality, and the level of physical mobility and functioning of older adults in Health Area 3 of the Region of Murcia. Methods: A descriptive, observational, and cross-sectional study was performed. The inclusion criteria were age ≥ 65, living in Health Area 3 of the Region of Murcia, and not being institutionalized. The following variables were evaluated: sociodemographic variables, loneliness (UCLA scale), social isolation (DUFSS), depression (GDS), cognitive deterioration (Pfeiffer), sleep quality (PSQI), and mobility (Barthel index). A univariate and multivariate regression model was created to examine how the dependent variable was related to the independent variables. Results: A total of 102 older adults participated in the study. Of these, 31.4% perceived unwanted loneliness and 14.7% low social support. The multivariate regression analysis showed that social isolation, geriatric depression, and cognitive deterioration were significant predictors of loneliness. Conclusions: The findings highlight the importance of developing multifaceted interventions that address not only social isolation but also other interrelated factors such as depression, cognitive deterioration, and sleep quality. The strategies should be centered on community programs and support networks. It is fundamental to perform longitudinal studies to better understand the causal relationships between these variables.

Psychosocial distress among spouses of persons with dementia before and after their partner's death

BACKGROUND

Spouses of persons living with dementia may face heightened psychosocial distress in the years immediately before and after their partner's death. We compared the psychosocial needs of spouses of partners with dementia with spouses of partners with non-impaired cognition nearing and after the end of life, focusing on loneliness, depression, life satisfaction, and social isolation.

METHODS

We used nationally representative Health and Retirement Study married couples data (2006-2018), restricting to spouses 50+ years old. We included 2098 spouses with data on loneliness and depressive symptoms 2 years before and after the partner's death. We additionally examined a subset of spouses (N = 1113) with available data on life satisfaction and social isolation 2 years before their partner's death. Cognitive status of partners was classified as non-impaired cognition, cognitive impairment not dementia (cognitive impairment), and dementia. We used multivariable logistic regression to determine: 1) the change in loneliness and depression for spouses pre- and post-partner's death, and 2) life satisfaction and social isolation 2 years before the partner's death.

RESULTS

Spouses were on average 73 years old (SD: 10), 66% women, 7% Black, 7% Hispanic non-White, 24% married to persons with cognitive impairment, and 19% married to partners with dementia. Before their partner's death, spouses married to partners with dementia experienced more loneliness (non-impaired cognition: 8%, cognitive impairment: 16%, dementia: 21%, p-value = 0.002) and depressive symptoms (non-impaired cognition: 20%, cognitive impairment: 27%, dementia: 31%, p-value < 0.001), and after death a similar prevalence of loneliness and depression across cognitive status. Before their partner's death, spouses of partners with dementia reported less life satisfaction (non-impaired cognition: 74%, cognitive impairment: 68%; dementia: 64%, p-value = 0.02) but were not more socially isolated.

CONCLUSION

Results emphasize a need for clinical and policy approaches to expand support for the psychosocial needs of spouses of partners with dementia in the years before their partner's death rather than only bereavement.

Combined rehabilitation and palliative care interventions for patients with life-threatening diseases - PREGOAL. A scoping review of intervention programme goals

PURPOSE

WHO recommends integrating rehabilitation into palliative care when providing services for people with life-threatening conditions. Recently, there has been increasing interest in exploring how rehabilitation and palliative care approaches could be combined. The aim of this study was to map and discuss the goals of intervention programmes that combine rehabilitation and palliative care.

METHODS

A scoping review was performed. The electronic databases MEDLINE, EMBASE, and CINAHL were searched for papers published between January 2014 and September 2022. Papers were considered eligible if the participants in question had a life-threatening disease and if interventions included both rehabilitation and palliative care. All study types were included.

RESULTS

Ten papers describing five interventions were included. Qualitative goals were narratively described, and quantitative goals were analysed according to the International Classification of Functioning, Disability and Health, and the Total Pain framework. Findings showed an overall focus on functioning and quality of life. Further analysis indicated an emphasis on physical and psychological dimensions. Social participation, and the social and spiritual dimensions were rarely evaluated.

CONCLUSION

This review indicates that goals relative to social participation, the social and spiritual dimensions, and the patient's own goals may well be overlooked as points of orientation for interventions.

Lifecourse trajectories and cross-generational trends in social isolation: Findings from five successive British birth cohort studies

Despite growing concerns in the UK about social isolation, there remains a lack of data on the extent and time trends of social isolation from longitudinal, population-based studies. There is also little research that assesses the multiple domains of social isolation across the lifecourse and between generations in a holistic way accounting for different contexts. By applying a multi-context, multi-domain framework of social isolation to 5 successive British birth cohorts, we provide conceptual and empirical understanding of social isolation trajectories across the lifecourse and identify potential generational and sex differences in trends. Where data were available, comparable social isolation indicators were generated to enable lifecourse trajectories and cross-generational trends to be explored. Information on isolation was available across the following relational contexts: household i.e., living alone; partnership, family and friends outside the household; education and employment networks; and community engagement. Trajectories were modelled stratified by sex using a multilevel growth curve framework. Data were analysed from 73,847 individuals (48.5% female), in 5 successive cohorts born in 1946 (N = 5,362), 1958 (N = 16,742), 1970 (N = 16,950), 1989-90 (N = 15,562), and 2000-01 (N = 19,231). Exploring a range of social isolation indicators across several contexts provided a nuanced picture of social isolation across the lifecourse and between generations in the UK, with no consistent pattern of increased or decreased isolation over time. For example, more people are living alone, less women are out of education and employment in midlife, more people are volunteering, but fewer people regularly engage in religious activity. It therefore highlights the need to focus on a range of social isolation indicators across contexts to understand how people compensate for specific types of isolation, and to understand structural differences in social configurations in the UK, which may not only define the timing and sequencing of life transitions but also social isolation.

Prognostic Value of Objective Social Isolation and Loneliness in Older Patients With Heart Failure: Subanalysis of FRAGILE-HF and Kitasato Cohort

BACKGROUND

Social factors encompass a broad spectrum of nonmedical factors, including objective (social isolation [SI]) and perceived (loneliness) conditions. Although social factors have attracted considerable research attention, information regarding their impact on patients with heart failure is scarce. We aimed to investigate the prognostic impact of objective SI and loneliness in older patients with heart failure.

METHODS AND RESULTS

This study was conducted using the FRAGILE-HF (Prevalence and Prognostic Value of Physical and Social Frailty in Geriatric Patients Hospitalized for Heart Failure; derivation cohort) and Kitasato cohorts (validation cohort), which included hospitalized patients with heart failure aged ≥65 years. Objective SI and loneliness were defined using the Japanese version of Lubben Social Network Scale-6 and diagnosed when the total score for objective and perceived questions on the Lubben Social Network Scale-6 was below the median in the FRAGILE-HF. The primary outcome was 1-year death. Overall, 1232 and 405 patients in the FRAGILE-HF and Kitasato cohorts, respectively, were analyzed. Objective SI and loneliness were observed in 57.8% and 51.4% of patients in the FRAGILE-HF and 55.4% and 46.2% of those in the Kitasato cohort, respectively. During the 1-year follow-up, 149 and 31 patients died in the FRAGILE-HF and Kitasato cohorts, respectively. Cox proportional hazard analysis revealed that objective SI, but not loneliness, was significantly associated with 1-year death after adjustment for conventional risk factors in the FRAGILE-HF. These findings were consistent with the validation cohort.

CONCLUSIONS

Objective SI assessed using the Lubben Social Network Scale-6 may be a prognostic indicator in older patients with heart failure. Given the lack of established SI assessment methods in this population, further research is required to refine such methods.

Social network and related factors in older people with sensory impairment in the community: Using principal component analysis

AIM

Older people with sensory impairment are more likely to have smaller and weaker social network due to their reduced ability, which lowers their quality of life. However, there is little research on the social network in older people with sensory impairment, especially the related factors. The aim of the study was to explore the related factors of social network and to provide evidence for the improvement of social network to promote successful aging in older people with sensory impairment.

METHODS

A cross-sectional study was conducted among 374 participants for hearing and vision assessment and questionnaire survey in a community, Beijing. Data were collected and analyzed by principal component analysis (PCA) and multiple logistic regression using IBM SPSS 25.0 software.

RESULTS

PCA showed that there were six risk factors whose eigenvalues >1 were extracted, with a total variance of 56.555%. Multiple logistic regression analysis of principal component indicated that five factors including physical health factor, social interaction factor, psychological status factor, lifestyle factor, and family condition factor, were statistically significant (p < 0.05).

CONCLUSIONS

The social network of older people with sensory impairment is relatively poor. Physical health factor, social interaction factor, psychological status factor, lifestyle factor, and family condition factor may be related factors. Medical staff should pay attention to physical, psychological and social characteristics of older people, especially with sensory impairment, to carry out necessary measures to improve social network and avoid social isolation.

Social connection and end-of-life outcomes among older people in 19 countries: a population-based longitudinal study

BACKGROUND

Social connection is a key determinant of health, but its role in shaping end-of-life outcomes is poorly understood. We examined changes in structure, function, and quality components of social connection in older people's last years of life, and the extent to which social connection predicts end-of-life outcomes (ie, symptoms, health-care utilisation, and place of death).

METHODS

This study used longitudinal data of representative samples from across 18 European countries and Israel in the Survey of Health, Ageing, and Retirement in Europe (SHARE), the largest European cohort study of people aged 50 years or older. We included deceased participants of waves 4 and 6 (which contained social network modules) for whom a proxy provided an end-of-life interview. We did paired sample t-tests (for continuous variables), Wilcoxon signed-rank tests (for ordinal variables), and McNemar's tests (for non-ordinal categorical variables) to assess changes in structure, function, and quality components of social connection between waves 4 and 6. To examine social connection as a predictor of end-of-life outcomes, we used social connection data from wave 6 core interviews and end-of-life interviews from wave 7, conducted with a proxy respondent covering the deceased participant's last year of life. End-of-life outcomes included symptoms (pain, breathlessness, and anxiety or sadness) in the last month of life, health-care utilisation in the last year of life, and place of death. We conducted a mixed-effects logistic regression analysis per social connection measure, for each end-of-life outcome.

FINDINGS

Data were collected in 2011-12 for wave 4, 2015-16 for wave 6, and 2017-18 for wave 7. We studied 3356 individuals (mean age at death was 79·7 years [SD 10·2]), with interviews conducted, on average, 4·6 (1·2) years (wave 4) and 1·1 (0·7) years (wave 6) before death. From wave 4 to wave 6, the following changes in social connection were observed: proportion of married or partnered participants (from 1406 [60·9%] of 2310 to 1438 [57·1%] of 2518; p<0·0001), receiving personal care or practical help (from 781 [37·2%] of 2099 to 1334 [53·1%] of 2512; p<0·0001), loneliness (from mean 1·4 [SD 0·5] to 1·5 [0·6]; p<0·0001; scale 1-3), satisfaction with social network (from 8·8 [1·67] to 8·7 [1·7]; p=0·037; scale 0-10), and emotional closeness to social network (eg, from 1883 [88·8%] of 2121 to 1710 [91·3%] of 1872 participants who indicated being either very close or extremely close to social network members; p<0·0001). Higher levels of loneliness at wave 6 predicted a greater likelihood of experiencing symptoms in the last month of life (odds ratio range across symptoms: 1·29 [95% CI 1·08-1·55] to 1·58 [1·32-1·89]). Being married (1·32 [1·03-1·68]) or receiving personal care or practical help (1·25 [1·04-1·49]) predicted death in hospital.

INTERPRETATION

Social connection undergoes multifaceted changes towards older people's end of life, countering prevalent ideas of generally declining social trajectories. Loneliness in the final months of life might be a risk factor for end-of-life symptoms. Further research is needed to substantiate a causal relationship and to identify underpinning mechanisms, which could inform screening and prevention measures.

Loneliness and Depressive Symptoms Are High Among Older Adults With Digestive Disease and Associated With Lower Perceived Health

BACKGROUND & AIMS

Current approaches to managing digestive disease in older adults fail to consider the psychosocial factors contributing to a person's health. We aimed to compare the frequency of loneliness, depression, and social isolation in older adults with and without a digestive disease and to quantify their association with poor health.

METHODS

We conducted an analysis of Health and Retirement Study data from 2008 to 2016, a nationally representative panel study of participants 50 years and older and their spouses. Bivariate analyses examined differences in loneliness, depression, and social isolation among patients with and without a digestive disease. We also examined the relationship between these factors and health.

RESULTS

We identified 3979 (56.0%) respondents with and 3131 (44.0%) without a digestive disease. Overall, 60.4% and 55.6% of respondents with and without a digestive disease reported loneliness (P < .001), 12.7% and 7.5% reported severe depression (P < .001), and 8.9% and 8.7% reported social isolation (P = NS), respectively. After adjusting for covariates, those with a digestive disease were more likely to report poor or fair health than those without a digestive disease (odds ratio [OR], 1.25; 95% CI, 1.11-1.41). Among patients with a digestive disease, loneliness (OR, 1.43; 95% CI, 1.22-1.69) and moderate and severe depression (OR, 2.93; 95% CI, 2.48-3.47; and OR, 8.96; 95% CI, 6.91-11.63, respectively) were associated with greater odds of poor or fair health.

CONCLUSIONS

Older adults with a digestive disease were more likely than those without a digestive disease to endorse loneliness and moderate to severe depression and these conditions are associated with poor or fair health. Gastroenterologists should feel empowered to screen patients for depression and loneliness symptoms and establish care pathways for mental health treatment.

Dynamic associations between vision and hearing impairment and depressive symptoms among older Chinese adults

BACKGROUND

Whether the impact of vision impairment (VI)/hearing impairment (HI) on depressive symptoms changes over time has not been investigated. This study aimed to examine the complex dynamic associations between VI/HI and depressive symptoms to design effective prevention strategies for older Chinese adults.

METHODS

Data were from the China Health and Retirement Longitudinal Study (CHARLS). The study identified self-reported VI, HI, depressive symptoms, and other covariates (including social isolation). Logistic regression models were used to analyze the dynamic associations across three waves, with the assessment of multiplicative and additive interactions.

RESULTS

Of the 8519 participants in wave 1 (mean [SD] age, 62.0 [8.0] years, 49.5 % male), 38.5 % had depressive symptoms. After adjusting for covariates including social isolation, VI and HI were significantly associated with depressive symptoms across all three waves. Specifically, the adjusted odds ratio (AOR) of VI increased from 2.08 (95 % CI: 1.89 to 2.29) in wave 1 to 2.15 (95 % CI: 1.90 to 2.44) in wave 3; while the AOR of HI increased from 1.80 (95 % CI: 1.58 to 2.04) in wave 1 to 2.11 (95 % CI: 1.75 to 2.51) in wave 3. The additive interactions between VI and HI on depressive symptoms in each wave (e.g., RERI [95 % CI]: 7.90 [2.51 to 12.30] in wave 1) were significant without adjusting for social isolation.

CONCLUSION

The study suggests that VI and HI are consistently associated with depressive symptoms among older adults in China over a four-year period, and their influences on mental health deserve more attention.

Social isolation and risk of disability in older adults: Effect modification of metabolic syndrome

PURPOSE

Delaying the onset of disabilities is a social challenge, especially in an aging society. Social isolation (SI) and metabolic syndrome (MetS) can coexist and pose the risks of disability onset. However, their interaction is not proven in older adults. Therefore, this study investigated whether SI combined with MetS exacerbates disability onset in older adults.

MATERIALS AND METHODS

A total of 3,738 community-dwelling older adults underwent a health check-up. After baseline assessments, we followed them up to assess disability incidence for five years. SI was defined as a condition in which two or more of the following measures were met: domestic isolation, less social contact, and social disengagement. MetS was defined according to the criteria of the International Diabetes Federation. We used Cox proportional hazard regression used to identify the interaction effect of SI and MetS on the risk of disability onset after adjusting for potential confounding factors.

RESULTS

Multivariate Cox proportional hazard regression showed a significant interaction effect of SI and MetS on disability onset. In the subgroup analysis stratified by MetS status, SI was identified as a risk factor for disability onset only in the MetS group, but not in the non-MetS group.

CONCLUSIONS

This five-year longitudinal study showed that the co-occurrence of SI and MetS increased the risk of disability onset in older adults. This indicates that the assessment of MetS in socially isolated older adults is important for healthcare providers to delay the onset of disabilities.

The Benefit of Air Conduction Pure-Tone Audiometry as a Screening Method for Hearing Loss over the VAS Score

Hearing loss is commonly encountered by general practitioners. We aimed to evaluate the screening benefit of air conduction pure-tone audiometry over visual analogue scale (VAS) scores for hearing loss. Moreover, we intended to perform the first cross-sectional study in Greece to assess hearing loss with pure-tone audiometry in young adults of the general population. We evaluated Greeks between 15 and 40 years old in a high school in Karditsa, Greece, and a primary health care unit in a nearby community. Subjects filled out a VAS score sheet and underwent pure-tone audiometry in a room without sound isolation, with air conduction only. We named the latter procedure modified pure-tone audiometry (mPTA). Subjects with pathologic results were examined via otoscopy and standardized pure-tone audiometry (sPTA). Of the 286 subjects evaluated, the VAS score revealed 5 subjects (1.7%) with hearing loss. mPTA (100 s duration) doubled this percentage (in total 3.8%; Pearson Chi-Square test; p < 0.001). Based on sPTA, the sensitivity and positive predictive value of the VAS score were 40% and 13%, respectively. For mPTA, they were 100% and 37%, respectively. mPTA filtered out pathologic cases in a proper, rapid, cheap and simple way and may be considered a proper screening method for hearing loss in primary health care.

Explaining how and why social support groups in hospice day services benefit palliative care patients, for whom, and in what circumstances

Background

Palliative care aims to provide holistic support for people with life-limiting illness, responding to psychological, social and spiritual needs, as well as to clinical and physical. In the United Kingdom, hospice day services (including day care, group interventions, group activities, and social events for palliative care outpatients) aim to provide opportunities for patients to gain social support, which is thought to improve their quality of life.

Objectives

This research explored social support within hospice day services, to explain in detail how and why social support obtained within a hospice day service could be beneficial to palliative care patients.

Design

Qualitative research using observations of hospice day services and interviews with service providers.

Methods

Data collection involved nineteen interviews with hospice service providers (n = 19) and researcher observations of hospice day services. The findings detail how patient and hospice context interact to produce mechanisms that lead to outcomes beyond the hospice day service.

Results

Practical, clinical and social aspects of the hospice day service are important for patients feeling welcome and safe in the setting. The opportunity to connect with other people and work towards personal goals can boost self-confidence for patients who have lost access to meaningful activity. New friendships between patients encourages reciprocal support and feelings of belonging. It is beneficial to have permission to speak freely about topics deemed inappropriate elsewhere, because honest communication is helpful in accepting and adapting to their circumstances.

Conclusion

Hospice day services facilitate group settings for reciprocal social support. This research proposes an initial programme theory that can be further developed and tested. It explains how and why, in some contexts, social support increases personal and practical resources to cope with illness and death, leading to changes outside of the hospice (to mood, interpersonal interactions and behaviour) that could improve quality of life.

The Role of Digital Technologies in Facilitating Psychosocial Resilience to Sudden Social Isolation Among Older Adults: Lessons Learned from the COVID-19 Pandemic

This study investigated how older adults adopted new technologies in response to sudden social isolation caused by the COVID-19 pandemic and how this adoption was related to their long-term psychosocial well-being. The study involved a 6-month longitudinal survey of 151 older adults and two phone-based focus groups, which informed a semi-structured interview guide and purposive sampling of diverse community-dwelling older adults. We then conducted twenty qualitative interviews and thematic analysis and mapped themes to 6-month quantitative trajectories of psychosocial health. Three themes emerged: first, most participants adopted multiple technologies to maintain social connection and psychosocial well-being. Second, participants felt left behind by certain technologies due to complicated systems or ageist societal norms. Third, pandemic-related community resources promoted technology independence among isolated older adults and those wanting to avoid "burdening" family. Results challenge ageist stereotypes and provide a framework for encouraging access and comfort with multiple technologies to adapt to sudden health crises or disruptive events.

Life-course transitions and exclusion from social relations in the lives of older men and women

There is increasing interest across European contexts in promoting active social lives in older age, and counteracting pathways and outcomes related to social isolation and loneliness for men and women in later life. This is evidenced within national and European level policy, including the 2021 Green Paper on Ageing and its concern with understanding how risks can accrue for European ageing populations in the relational sphere. Research indicates that life-course transitions can function as a source of these risks, leading to a range of potentially exclusionary impacts for the social relations of older men and women. Findings presented in this paper are drawn from the qualitative component of a larger European mixed-methods study on exclusion from social relations (GENPATH: A life course perspective on the GENdered PATHways of social exclusion in later life, and its consequences for health and well-being). We use data from 119 in-depth interviews from four jurisdictions: Austria, Czechia, Ireland and Spain. This research employed an approach that focused on capturing lived experienced insights related to relational change across the life course, the implications of these changes for multifaceted forms of exclusion from social relations and the role of gender in patterning these changes and implications. We focused on transitions that commonly emerged across those jurisdictions for older people: onset of ill-health, bereavement, retirement and relocation. We found that these transitions translate into multidimensional experiences of exclusion from social relations in the lives of older men and women by constraining their social networks, support networks, social opportunities and intimate relationships.

Social Isolation and Loneliness in a Population Study of Cognitive Impairment: The MYHAT Study

In this study, we examined associations of social isolation and loneliness with cognitive impairment among older adults from a Rust Belt region in Southwest Pennsylvania. We used data from the population-based Monongahela-Youghiogheny Healthy Aging Team (MYHAT) study. We found that (a) 11 items combined into two reliable composites of social isolation and loneliness; (b) unique to this study, providing unpaid help to others was an indicator of reduced social isolation; (c) social isolation and loneliness were positively associated with cognitive impairment; and (d) these associations were appreciably attenuated by general health and physical functional status and depressive symptoms, respectively. We concluded that social isolation and loneliness are differentially associated with older adults' cognitive health, and that their effects might operate through separate pathways. Approaches to address social isolation and loneliness should consider the community context and its implications for older adults' cognitive health.

National Prevalence of Social Isolation and Loneliness in Adults with Chronic Obstructive Pulmonary Disease

Rationale: Social isolation and loneliness are gaining recognition for their role in health outcomes, yet they have not been defined in people with chronic obstructive pulmonary disease (COPD). Objective: To determine the national prevalence of and characteristics associated with social isolation and loneliness in people with COPD. Methods: This is a cross-sectional study of community-dwelling adults aged ⩾50 years in the nationally representative HRS (Health and Retirement Study) (2016-2018). Participants self-reported COPD and supplemental oxygen use and were categorized into three groups: 1) no COPD; 2) COPD; and 3) COPD on oxygen. Social isolation was defined using a nine-item scale indicating minimal household contacts, social network interaction, and community engagement. Loneliness was measured using the 3-Item UCLA Loneliness Scale. Multivariable logistic regression defined prevalence and associated characteristics for both. Results: Participants (n = 10,384) were on average 68 years old (standard deviation, ±10.5), 54% female, 10% Black, 11% self-reported COPD, and 2% self-reported supplemental oxygen. Overall, 12% were socially isolated, 12% lonely, and 3% both socially isolated and lonely. People with COPD had a higher adjusted prevalence of social isolation (no COPD: 11%; COPD: 16%; COPD on oxygen: 20%; P < 0.05) and loneliness (no COPD: 11%; COPD: 18%; COPD on oxygen: 22%; P < 0.001). In those with COPD, characteristics associated with social isolation (P < 0.05) included sex (men: 22%; women: 13%), non-Hispanic White ethnicity (White: 19%; Black: 7%), low net worth (<$6,000: 32%; $81,001-$239,000: 10%), depression (depression: 24%; no depression: 14%), having difficulty with one or more activities of daily living (one or more difficulty: 22%; no difficulty: 14%), and current cigarette use (current: 24%; never: 13%). Characteristics associated with loneliness (P < 0.05) included younger age (50-64 yr: 22%; 75-84 yr: 12%), being single (single: 32%; married: 12%), depression (depression: 36%; no depression: 13%), having difficulty with one or more activities of daily living (one or more difficulty: 29%; no difficulty: 15%), diabetes (diabetes: 26%; no diabetes: 17%), and heart disease (heart disease 23%; no heart disease: 17%). Conclusions: Nearly one in six adults with COPD experience social isolation, and one in five experience loneliness, with almost twice the prevalence among those on supplemental oxygen compared with the general population. Demographic and clinical characteristics identify those at highest risk to guide clinical and policy interventions.

Association of COVID-19 Infection with Sociodemographic, Anthropometric and Lifestyle Factors: A Cross-Sectional Study in an Older Adults' Population Aged over 65 Years Old

BACKGROUND

The COVID-19 pandemic has led to unfavorable disruptions to daily living routines by exerting deleterious effects on several aspects of human mental and physical health and quality of life worldwide. The purpose of the current survey is to explore the potential association of COVID-19 infection with multiple sociodemographic, anthropometric, and lifestyle factors of community-dwelling older adults.

METHODS

This is a cross-sectional survey including 5197 older adults aged over 65 years old from 10 geographically diverse regions of Greece. Relevant questionnaires were used to record study the population sociodemographic factor, while anthropometric parameters were also measured. Validated questionnaires were also applied to assess several lifestyle factors such as depression, anxiety, stress, cognitive status, sleep quality, health-related quality of life, physical activity levels, and Mediterranean diet (MD) adherence.

RESULTS

In multivariate regression analysis, COVID-19 infection was significantly, independently related with urban residence (p = 0.0107), regular smoking (p = 0.0218), overweight status and obesity (p = 0.0036), as well as abdominal obesity (p = 0.0008), higher risk of depression (p = 0.0027), anxiety (p = 0.0045), stress (p = 0.0038), inadequate sleep quality (p = 0.0108), lower physical activity levels (p = 0.0012), reduced MD compliance (p = 0.0009), and poor health-related quality of life (p = 0.0002). In univariate analysis, older adults' age (p = 0.0001), male gender (p = 0.0015), living alone (p = 0.0023), lower educational and economic level (p = 0.0175 and p = 0.0294, respectively), and cognition decline (p = 0.0032) were also related with the presence of COVID-19 infection; however, these associations were considerably attenuated at a non-significant level by adjustment for several confounders in multivariate analysis.

CONCLUSIONS

This is one of the few available studies supporting evidence that COVID-19 infection may be associated with diverse sociodemographic, anthropometric, and lifestyle factors in an older adults' population in Greece. This study highlights the strong demand to provide psychological and nutritional counselling and support to older adults diagnosed with COVID-19 infection in order to ameliorate disease symptoms and severity, emphasizing the adaptation of healthy dietary and lifestyle habits as preventing and supplementary therapeutic factors against COVID-19.

Loneliness during the COVID-19 Pandemic in Patients with Burning Mouth Syndrome: A Multicentric Case-Control Italian Study

Background

Lockdown restrictions during the COVID-19 pandemic exerted a strong impact on people's quality of life and increased loneliness. This study evaluates the effect of the pandemic on loneliness in patients with burning mouth syndrome (BMS) compared with the general population.

Methods

100 BMS patients versus 100 healthy controls (HC) were recruited in five Italian centers. The 12-Item General Health Questionnaire (GHQ-12), the Depression Anxiety Stress Scales-21 (DASS-21), the Insomnia Severity Index (ISI), the short-form UCLA Loneliness Scale-8 (ULS-8), the Multidimensional Scale of Perceived Social Support (MSPSS), and the Suicidal Ideation Attribute Scale (SIDAS) were administered.

Results

BMS patients and HC showed high scores (16 [14-20.25] and 16 [14-18]) in the ULS-8. Statistically significant differences have been found considering the BMS patients lived with fewer relatives during the lockdown compared with the HC (2 [2-3] and 3 [2-4]; p: 0.012) with a lower level of satisfaction in relationships with relatives (4 [1.75-5] and 5 [4-5]; p < 0.001) and also in the DASS-21 total scores between the BMS patients and HC (16 [10-24.2] and 10 [4-17]; p < 0.001). The multivariate logistic regression revealed that age, education, DASS-21, and MSPSS were the most predictive variables and could explain 34.68% of the variance in the ULS-8 score (p < 0.001) in the BMS group. However, only the DASS-21 was significant in the HC group, explaining 10.11% of the variance of the ULS-8 (p: 0.033).

Conclusions

Both the patients and controls experienced deep loneliness during the pandemic. However, in the BMS group, loneliness was significantly correlated with age, a higher level of education and stress, and a lower level of satisfaction in relationships with relatives and social support perceived compared with the controls.

Age-related hearing loss and dementia-related neuropathology: An analysis of the United Kingdom brains for dementia research cohort

Age-related hearing loss frequently precedes or coexists with mild cognitive impairment and dementia. The role specific neuropathologies play in this association, as either a cause or a consequence, is unclear. We therefore aimed to investigate whether specific dementia related neuropathologies were associated with hearing impairment in later life. We analysed data on ante-mortem hearing impairment with post-mortem neuropathological data for 442 participants from the Brains for Dementia Research Cohort. Binary logistic regression models were used to estimate the association of hearing impairment with the presence of each dementia-related neuropathology overall, and with specific staged changes. All analyses adjusted for age and sex, and several sensitivity analyses were conducted to test the robustness of findings. Presence and density of neuritic plaques were associated with higher odds of hearing impairment ante-mortem (OR = 3.65, 95% CI 1.78-7.46 for frequent density of plaques). Presence of any LB disease was likewise associated with hearing impairment (OR = 2.10, 95% CI 1.27-3.48), but this did not increase with higher cortical pathology (OR = 1.53, 95% CI 0.75-3.11). Nonspecific amyloid deposition, neurofibrillary tangle staging, overall AD neuropathology level, and cerebrovascular disease were not clearly associated with increased risks of hearing impairment. Our results provide some support for an association between dementia-related neuropathology and hearing loss and suggest that hearing loss may be associated with a high neuritic plaque burden and more common in Lewy body disease.

In sickness and in health: Loneliness, depression, and the role of marital quality among spouses of persons with dementia

BACKGROUND

Older adults married to persons living with dementia (PLwD) may be at risk for loneliness and depression. We assessed the prevalence of loneliness and depressive symptoms among spouses of PLwD or cognitive impairment not dementia (CIND), and the role of marital quality in mediating these outcomes.

METHODS

We used a US population-based sample of 4071 couples enrolled in the Health and Retirement Study (2014 and 2016). We included older adults married to PLwD (N = 227), married to persons with CIND (N = 885), or married to persons with no cognitive impairment (NCI) (N = 2959). We determined the prevalence of loneliness (UCLA 3-item scale), depressive symptoms (CESD-8 scale), and both, using multivariable logistic regression adjusting for sociodemographic and health-related characteristics. We then tested for interaction terms between marital quality (4-item scale) and degree of spousal cognitive impairment for each outcome of loneliness and depressive symptoms.

RESULTS

The sample was 55% women and on average 67-years-old (range: 50-97). After adjustment, spouses of persons with cognitive impairment were more likely to be lonely (NCI: 20%, CIND: 23%, PLwD: 29%; p = 0.04), depressed (NCI: 8%, CIND: 15%, PLwD: 14%; p < 0.01), and both (NCI: 4%, CIND: 9%, PLwD: 7%; p < 0.01). The association between cognition and loneliness, but not depression, differed by marital quality (interaction p-value = 0.03). Among couples with high marital quality, spousal cognitive impairment was associated with higher likelihood of loneliness (p < 0.05). In contrast, no association existed between spousal cognition and loneliness among couples with lower marital quality (p = 0.37).

CONCLUSIONS

One in six spouses of persons with CIND or more advanced disease (PLwD) experienced depressive symptoms, and loneliness among spouses of PLwD was experienced at a twofold rate. By identifying and managing both, and facilitating interventions that promote high-quality social connection, clinical teams might improve the lives of older couples facing dementia.

Association between pain intensity and depressive symptoms in community-dwelling adults: longitudinal findings from the Survey of Health, Ageing and Retirement in Europe (SHARE)

PURPOSE

To investigate the longitudinal associations between pain and depressive symptoms in adults.

METHODS

Prospective cohort study on data from 28,515 community-dwelling adults ≥ 50 years, free from depression at baseline (Wave 5), with follow-up in Wave 6 of the Survey of Health, Ageing and Retirement in Europe (SHARE). Significant depressive symptoms were defined by a EURO-D score ≥ 4. The longitudinal association between baseline pain intensity and significant depressive symptoms at follow-up was analysed using logistic regression models; odds ratios (ORs) and confidence intervals (CI) were calculated, adjusting for socio-demographic and clinical factors, physical inactivity, loneliness, mobility and functional impairments.

RESULTS

Mean age was 65.4 years (standard deviation 9.0, range 50-99); 14,360 (50.4%) participants were women. Mean follow-up was 23.4 (standard deviation 3.4) months. At baseline, 2803 (9.8%) participants reported mild pain, 5253 (18.4%) moderate pain and 1431 (5.0%) severe pain. At follow-up, 3868 (13.6%) participants-1451 (10.3%) men and 2417 (16.8%) women-reported significant depressive symptoms. After adjustment, mild, moderate and severe baseline pain, versus no pain, were associated with an increased likelihood of significant depressive symptoms at follow-up: ORs (95% CI) were 1.20 (1.06-1.35), 1.32 (1.20-1.46) and 1.39 (1.19-1.63), respectively. These associations were more pronounced in men compared to women, and consistent in participants aged 50-64 years, those without mobility or functional impairment, and those without loneliness at baseline.

CONCLUSION

Higher baseline pain intensity was longitudinally associated with a greater risk of significant depressive symptoms at 2-year follow-up, in community-dwelling adults without baseline depression.

A 50-state survey study of thoughts of suicide and social isolation among older adults in the United States

BACKGROUND

We aimed to characterize the prevalence of social disconnection and thoughts of suicide among older adults in the United States, and examine the association between them in a large naturalistic study.

METHODS

We analyzed data from 6 waves of a fifty-state non-probability survey among US adults conducted between February and December 2021. The internet-based survey collected the PHQ-9, as well as multiple measures of social connectedness. We applied multiple logistic regression to analyze the association between presence of thoughts of suicide and social disconnection. Exploratory analysis, using generalized random forests, examined heterogeneity of effects across sociodemographic groups.

RESULTS

Of 16,164 survey respondents age 65 and older, mean age was 70.9 (SD 5.0); the cohort was 61.4 % female and 29.6 % male; 2.0 % Asian, 6.7 % Black, 2.2 % Hispanic, and 86.8 % White. A total of 1144 (7.1 %) reported thoughts of suicide at least several days in the prior 2 week period. In models adjusted for sociodemographic features, households with 3 or more additional members (adjusted OR 1.73, 95 % CI 1.28-2.33) and lack of social supports, particularly emotional supports (adjusted OR 2.60, 95 % CI 2.09-3.23), were independently associated with greater likelihood of reporting such thoughts, as was greater reported loneliness (adjusted OR 1.75, 95 % CI 1.64-1.87). The effects of emotional support varied significantly across sociodemographic groups.

CONCLUSIONS

Thoughts of suicide are common among older adults in the US, and associated with lack of social support, but not with living alone.

The association of gait speed and self-reported difficulty walking with social isolation: A nationally-representative study

BACKGROUND

Mobility assessments are commonly used among older adults as risk stratification for falls, preoperative function, frailty, and mortality. We determined if gait speed and self-reported difficulty walking are similarly associated with social isolation and loneliness, which are key markers of social well-being and linked to health outcomes.

METHODS

We used 2015-2016 data from the National Social life Health and Aging Project (NSHAP), an in-person nationally-representative survey of 2640 community-dwelling adults ≥65 years old. We measured gait speed (timed 3-m walk: unable to walk, ≥5.7 s, and <5.7 s), and self-reported difficulty walking one block or across the room (unable, "much," "some," or "no" difficulty). Social measures included loneliness (3-item UCLA scale), social isolation (12-item scale), and individual social activities (frequency socializing, religious participation, community participation, and volunteering). We used logistic regression to determine the adjusted probability of each social measure by gait speed and difficulty walking, adjusting for sociodemographic and health characteristics, and tested for interaction terms with age.

RESULTS

Participants were on average 75 years old (SD = 7.1), 54% female, 9% Black/African American, and 6% Hispanic. Difficulty walking one block was associated with (p < 0.05): social isolation (much difficulty: 26% vs no difficulty: 18%), low socializing (33% vs 19%), low volunteering (67% vs 53%), low community participation (54% vs 43%), low religious participation (51% vs 46%), and loneliness (25% vs 14%). Difficulty walking across the room was similarly strongly associated with social isolation and individual activities. The association between self-reported difficulty walking and social isolation was stronger at older ages (p-value of interaction <0.001).

CONCLUSIONS

Self-reported mobility difficulty is a widely used clinical assessment that is strongly associated with loneliness and social isolation, particularly at older ages. Among persons with limited mobility, clinicians should consider a careful social history to identify social needs and interventions addressing mobility to enhance social connections.

Loneliness and older adults: psychological resilience and technology use during the COVID-19 pandemic-a cross sectional study

Introduction: This study investigated how psychological resilience influenced greater technology use among older adults, and whether they moderated the impact of social isolation on loneliness during the COVID-19 pandemic. We also explored whether technology mediates the impact of psychological resilience on loneliness. To explain the relationship between variables, the research drew upon the socio-emotional selective theory, which posits the notion that older adults are more focused on current and emotionally important relationships and goals concerning emotional regulation goals such as psychological well-being. Methods: Using a cross-sectional observational design, data were collected from 92 residents aged 65 to 89 in England from March 2020 to June 2021. Participants completed the Connor-Davidson Resilience Scale, Technology Experience Questionnaire, UCLA Loneliness Scale, and Lubben Social Network Index. Pearson correlation, mediation and moderation analyses were conducted to investigate the hypotheses. Results: Most participants experienced moderate to severe levels of loneliness, displaying higher levels than pre-pandemic. Psychological resilience predicted greater technology use, and lower levels of loneliness. Technology was found to mediate the relationship between psychological resilience and loneliness. Neither technology use, nor psychological resilience was found to moderate the impact of social isolation on loneliness. Discussion: Findings suggested that strategies directed towards screening older adults for psychological resilience levels and low technology experience may help identify those most at risk for adapting poorly when exposed to stressors in situations like the Covid-19 pandemic. Early interventions can be initiated to increase psychological resilience and technology use, including empirical interventions, that may help decrease loneliness, especially in times of elevated risks for loneliness.

Correlates of common concerns in older cancer survivors of leukemia and lymphoma: results from the WHI LILAC study

PURPOSE

Older survivors of leukemia and lymphoma often experience long-term effects of chemotherapy. We described common concerns related to their cancer and treatment in older survivors of leukemia and non-Hodgkin lymphoma (NHL) and assessed correlates of these concerns.

METHODS

We utilized data from the Women's Health Initiative (WHI) Life and Longevity After Cancer (LILAC) study that recruited post-menopausal women aged 50-79. Participants diagnosed with leukemia and NHL were included (n = 420). They were asked about 14 areas of current concerns related to their cancer and treatment and to rate each from 0 (no concern) to 2 (major concern), with total scores ranging from 0 to 28. Linear regression was used to assess factors correlated with the concern score, and logistic regression for factors correlated with the three most common concerns.

RESULTS

Mean age at assessment was 81 years (range 69-99); 72% reported at least one concern, and median concern score among these survivors was 3.5 (Q1-Q3 2-5). Factors significantly correlated with concern scores were sadness, pain, distress, higher prior symptom count, and loneliness (all p < 0.05). Significant factors correlated with common concerns were (1) fatigue/sleep: sadness/depression, distress, higher prior symptom count, greater loneliness, and worse physical functioning; (2) physical functioning/activity: older age, public insurance, higher body mass index, pain, worse QoL, and higher treatment-related comorbidities; (3) memory/concentration: prior chemotherapy or radiation, worse QoL, higher prior symptom count, and greater loneliness (all p < 0.05).

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

Almost three-quarters of older survivors of leukemia and lymphoma reported at least one concern; a multifaceted intervention may be needed to address these concerns.

Prevalence of loneliness and social isolation among older adults during the COVID-19 pandemic: A systematic review and meta-analysis

OBJECTIVES

Pandemics and their public health control measures have generally substantially increased the level of loneliness and social isolation in the general population. Because of the circumstances of aging, older adults are more likely to experience social isolation and loneliness during pandemics. However, no systematic review has been conducted or published on the prevalence of loneliness and/or social isolation among the older population. This systematic review and meta-analysis aims to provide up-to-date pooled estimates of the prevalence of social isolation and loneliness among older adults during the COVID-19 pandemic and other pandemics in the last two decades.

DESIGN

EMBASE, PsychoINFO, Medline, and Web of Science were searched for relevant studies from January 1, 2000 to November 31, 2021 published in a variety of languages. Only studies conducted during the COVID-19 pandemic were selected in the review.

RESULTS

A total of 30 studies including 28,050 participants met the inclusion criteria. Overall, the pooled period prevalence of loneliness among older adults was 28.6% (95% CI: 22.9-35.0%) and 31.2% for social isolation (95% CI: 20.2-44.9%). Prevalence estimates were significantly higher for those studies conducted post 3-month from the start of the COVID-19 pandemic compared to those conducted within the first 3 months of the pandemic.

CONCLUSIONS

This review identifies the need for good quality longitudinal studies to examine the long-term impact of pandemics on loneliness and social isolation among older populations. Health policymaking and healthcare systems should proactively address the rising demand for appropriate psychological services among older adults.

End-of-life health care use among socially isolated and cognitively impaired older adults

BACKGROUND

Social isolation is common in the last years of life, especially among individuals with cognitive impairment (CI), but it is unknown if social isolation is related to end-of-life health care use.

METHODS

We used nationally-representative 2006-2018 Health and Retirement Study (HRS) data linked to Medicare claims, including adults age ≥65 interviewed in the last 4 years of life (N = 2380). We used a validated social isolation scale and three social isolation subscales: (1) household contacts (marital status, household size, nearby children), (2) social network interaction (with children, family, and friends), and (3) community engagement. End-of-life health outcomes included 2+ emergency department (ED) visits in the last month of life, hospitalizations or ICU stays in the last 6 months of life, and any hospice use. CI was defined using the validated Langa-Weir methodology. We used logistic regression to test the association of each social isolation measure with each end-of-life outcome, adjusted for sociodemographic covariates, and tested for interaction terms with CI (p < 0.2).

RESULTS

The mean age of our sample of decedents was 81.2 (SD = 9.9), 53% were female, 8% Black, and 4% Hispanic. Overall, social isolation and the community engagement subscale were not associated with end-of-life health care use. Fewer household contacts were associated with lower hospice use (aOR = 0.74, p = 0.005). There were significant interaction terms between the social network interaction subscale and CI for ED use (p = 0.009) and hospitalizations (p = 0.04), and a trend for ICU stays (p = 0.15); individuals with both low social network interaction and CI had lower health care use across all three outcomes compared to other groups.

CONCLUSIONS

Individuals with fewer household contacts had lower hospice use, and cognitively impaired individuals with low social network interaction had fewer end-of-life ED visits, hospitalizations, and ICU stays. Clinicians should consider mobilizing external support services to ensure access to goal-concordant care for older adults with limited end-of-life social contact when needed.

Factors Associated With Social Isolation in Older Adults: A Systematic Review and Meta-Analysis

OBJECTIVE

Social isolation is a global health issue that affects older adults throughout their lives. This study aimed to identify the factors associated with social isolation in older adults.

DESIGN

Systematic review and meta-analysis.

SETTING AND PARTICIPANTS

Adults aged 60 years and older.

METHODS

We searched for observational studies without language restrictions in 11 databases from inception to August 2022. Pooled odds ratio (OR) and 95% CI were calculated using the R software (version 4.2.1). The modified Newcastle-Ottawa Scale was used to evaluate the risk of bias.

RESULTS

Eighteen factors were grouped into 5 themes. The following 13 factors were statistically significant: (1) demographics theme: aged 80 years and older (OR: 2.41; 95% CI: 1.20-4.85), less than or equal to a high school degree (OR: 1.68; 95% CI: 1.44-1.97), smoking (OR: 1.43; 95% CI: 1.18-1.73), and male (OR: 1.38; 95% CI: 1.01-1.89); (2) environment theme: low social support (OR: 7.77; 95% CI: 3.45-17.50) and no homeownership (OR: 1.38; 95% CI: 1.25-1.51); (3) role theme: no social participation (OR: 3.18; 95% CI: 1.30-7.80) and no spouse (OR: 2.61; 95% CI: 1.37-4.99); (4) physical health: hearing loss (OR: 2.78; 95% CI: 1.54-5.01), activities of daily living impairment (OR: 2.38; 95% CI: 1.57-3.61), and poor health status (OR: 1.52; 95% CI: 1.32-1.74); and (5) mental health: cognitive decline (OR: 1.85; 95% CI: 1.40-2.45) and depression (OR: 1.72; 95% CI: 1.21-2.44).

CONCLUSIONS AND IMPLICATIONS

Social isolation in older adults is associated with various factors. Hence, focused intervention should be adopted for older adults. In addition, further longitudinal studies are required to confirm a direct link between multiple factors and social isolation.

Social isolation and 9-year dementia risk in community-dwelling Medicare beneficiaries in the United States

BACKGROUND

Social isolation can influence whether older adults develop dementia. We examine the association between social isolation and incident dementia among older adults in a nationally representative sample of community dwelling older adults in the United States (U.S.). We also investigate whether this association varies by race and ethnicity.

METHODS

Data (N = 5022) come from the National Health and Aging Trends Study, a longitudinal and nationally representative cohort of older adults in the U.S. A composite measure of social isolation was used to classify older adults as socially isolated or not socially isolated at baseline. Demographic and health factors were measured at baseline via self-report. Dementia was measured at each round of data collection. Discrete-time proportional hazard time-to-event models were used to assess the association between social isolation and incident dementia over 9 years (2011-2020).

RESULTS

Of 5022 older adults, 1172 (23.3%) were socially isolated, and 3850 (76.7%) were not socially isolated. Adjusting for demographic and health factors, being socially isolated (vs. not socially isolated) was associated with a 1.28 (95% CI: 1.10-1.49) higher hazard of incident dementia over 9 years. There was no statistically significant difference by race and ethnicity.

CONCLUSION

Social isolation among older adults is associated with greater dementia risk. Elucidating the pathway by which social isolation impacts dementia may offer meaningful insights for the development of novel solutions to prevent or ameliorate dementia across diverse racial and ethnic groups.

Cognitive, physical, and mental profiles of older adults with misplaced self-evaluation of hearing loss

BACKGROUND

Although inconsistency between objective and subjective hearing loss among older adults has been suggested, a systematic examination of the cognitive and physical functioning among such older adults is lacking. Our objective was to assess the cognitive, physical, and mental profiles associated with the discrepancy.

METHODS

The auditory acuity of 696 community-dwelling older adults was evaluated using a pure-tone average of hearing thresholds at 1.0 and 4.0 kHz in the better-hearing ear. Participants were then stratified as follows: normal hearing ≤ 25 dB, mild loss >25 dB and ≤40 dB, and moderate loss >40 dB and ≤70 dB. Global cognition, gait speed, and depressive symptoms were also assessed.

RESULTS

Among older adults, 63.5% of those with mild hearing loss and 22.2% of those with moderate hearing loss did not recognize hearing difficulties. Significantly lower cognition and gait performance were observed in those with moderate hearing loss without subjective hearing loss (i.e., overestimation of hearing acuity) than in those with subjective hearing loss. Furthermore, older adults with subjective hearing loss showed a higher tendency toward depression than those without subjective hearing loss, irrespective of objective hearing loss.

CONCLUSIONS

Our results suggest that failure to recognize a high level of age-related hearing loss may be related to impaired cognition and gait performance among older adults. Subjective hearing loss may indicate a tendency toward depression.

Understanding the Role of Support in Digital Mental Health Programs With Older Adults: Users' Perspective and Mixed Methods Study

BACKGROUND

Digital mental health interventions have the potential to increase mental health support among isolated older adults. However, the older adult population can experience several barriers to accessing and using digital health resources and may need extra support to experience its benefits.

OBJECTIVE

This paper aimed to understand what older adults experience as an important aspect of support during engagement in a digital mental health program. The program entailed 3 months of staff support to participate in digital literacy training and engage with the digital mental health platform myStrength, which offers support for a range of mental health challenges, including depression and anxiety.

METHODS

A total of 30 older adults participated in surveys and interviews to assess their experience of participating in a digital mental health program provided by county mental health services. As part of the program, participants attended 4 classes of digital literacy training, had access to the digital mental health platform myStrength for 2 months with staff support (and 10 months after the program without support), and received support from program staff during the entire 3-month program. Survey data were analyzed using descriptive statistics, and interview data were analyzed using thematic analysis.

RESULTS

A thematic analysis of the interview data revealed that participants valued ongoing support in 3 main areas: technical support to assist them in using technology, guided support to remind them to use myStrength and practice skills they had learned, and social support to enable them to connect with others through the program. Furthermore, participants reported that social connections was the most important aspect of the program and that they were mainly motivated to participate in the program because it was recommended to them by trusted others such as a community partner or because they believed it could potentially help others.

CONCLUSIONS

Our findings can be used to inform the design of future digital mental health programs for older adults who may have unique support needs in terms of dedicated technical support and ongoing guided support to use technology and social support to increase social connectedness.

Persistent loneliness due to COVID-19 over 18 months of the pandemic: A prospective cohort study

BACKGROUND

Loneliness was common early in the COVID-19 pandemic due to physical distancing measures, but little is known about how loneliness persisted into later stages of the pandemic. We therefore examined longitudinal trajectories of loneliness over 18 months of the pandemic and subgroups at risk for persistent loneliness.

METHODS

We used data from the COVID-19 & Chronic Conditions study collected between March 27, 2020 to December 10, 2021, including 641 predominantly older adults with ≥1 chronic condition who completed six interviews at approximately 3 month intervals. Participants reported loneliness (defined as some, most, or all of the time) during the past week due to COVID-19. We used trajectory mixture models to identify clusters of individuals following similar trajectories of loneliness, then determined subgroups likely to be classified in different loneliness trajectories using multivariable regression models adjusted for sociodemographic and clinical covariates.

RESULTS

Participants were on average 63 years old, 61% female, 30% Black, 20% Latinx, and 29% were living below the poverty level. There was an overall reduction in loneliness over time (March to April/2020: 51% to September to December/2021: 31%, p = 0.01). Four distinct trajectory groups emerged: (1) "Persistent Loneliness" (n = 101, 16%); (2) "Adapted" (n = 141, 22%), individuals who were initially lonely, with feelings of loneliness decreasing over time; (3) "Occasional loneliness" (n = 189, 29%); and (4) "Never lonely" (n = 211, 33%). Subgroups at highest risk of the "Persistently Lonely" trajectory included those identifying as Latinx (aOR 2.5, 95% CI: 1.2, 5.2), or living in poverty (aOR 2.5; 95% CI: 1.4, 4.6).

CONCLUSIONS

Although loneliness declined for a majority of older adults during the pandemic in our sample, persistent loneliness attributed to the COVID-19 pandemic was common (1 in 6 adults), particularly among individuals identifying as Hispanic/Latinx or living in poverty. Interventions addressing loneliness can ease pandemic-related suffering, and may mitigate long-term mental and physical health consequences.

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.

Insights into the Social Determinants of Health in Older Adults

In this paper, we review the social determinants of health in older adults and their complex interrelationship with medical diseases. Also, we provide recommendations to address these determinants in the integrated healthcare plan. The social determinants in older adults and its influence in health outcomes have been studied for decades. There is solid evidence for the interrelationship between social factors and the health of individuals and populations; however, these studies are unable to define their complex interrelatedness. Health is quite variable and depends on multiple biological and social factors such as genetics, country of origin, migrant status, etc. On the other hand, health status can affect social factors such as job or education. Addressing social determinants of health in the integrated healthcare plan is important for improving health outcomes and decreasing existing disparities in older adult health. We recommend a person-centered approach in which individualized interventions should be adopted by organizations to improve the health status of older adults at the national and global level. Some of our practical recommendations to better address the social determinants of health in clinical practice are EHR documentation strategies, screening tools, and the development of linkages to the world outside of the clinic and health system, including social services, community activities, collaborative work, and roles for insurance companies.
