Measuring social isolation among older adults using multiple indicators from the NSHAP study

Using machine learning to understand social isolation and loneliness in schizophrenia, bipolar disorder, and the community

Social disconnection, including objective social isolation and subjective loneliness, is linked to substantial health risks. Yet, little is known about the predictors of social disconnection in individuals with mental illness. Here, we used machine learning to identify predictors of social isolation and loneliness in schizophrenia (N = 72), a psychiatric condition associated with social disconnection. For comparison, we also included two other groups: a psychiatric comparison sample of bipolar disorder (N = 48) and a community sample enriched for social isolation (N = 151). We fitted statistical models of social isolation and loneliness within and across groups. Each model included five candidate predictors: social avoidance motivation, depression, nonsocial cognition, social anhedonia, and social cognition. The results showed that social anhedonia explained unique variance in social isolation and loneliness in all samples, suggesting that it contributes to social isolation and loneliness broadly. However, nonsocial cognition explained unique variance in social isolation only within schizophrenia. Thus, social anhedonia could be a potential intervention target across populations, whereas nonsocial cognition may play a unique role in determining social disconnection in schizophrenia.

Social isolation in people with type 2 diabetes: A concept analysis

Objective

To identify the defining attributes, antecedents, consequences and empirical referents to form an operational definition of social isolation in people with type 2 diabetes.

Design

The Walker and Avant approach.

Data source

An electronic search of the literature using China National Knowledge Infrastructure (CNKI), Wanfang database, PubMed, Web of Science, CINAHL, and PsycINFO informed the analysis. The search included both quantitative and qualitative studies related to social isolation in people with type 2 diabetes published in Chinese and English.

Results

Of the 2918 articles identified, 21 ultimately met the inclusion criteria. The analysis identified the defining attributes of social isolation in people with type 2 diabetes as objective and subjective. Antecedents included five aspects: personal characteristics, disease-related physiological factors, and psychological, behavioral, and social factors. Consequences were identified as physiological, psychological, behavioral aspects and quality of life.

Conclusions

The operational definition of social isolation in people with type 2 diabetes is that due to personal characteristics, disease-related physiological factors, and psychological, behavioral, and social factors, people with type 2 diabetes will have limited social networks and social support, reduced social contact and social involvement, and/or negative feelings of disconnection from the outside world, which lead to adverse physiological, psychological, and behavioral outcomes and poor quality of life. Clinicians can further develop tools to measure social isolation in people with type 2 diabetes and analyze the path of the antecedents to social isolation to investigate the interplay between them in order to develop target interventions.

The Impact of Kinlessness on Older Adults with Advanced Heart Failure

Markers of social health, including kinlessness, social isolation and loneliness, have important implications for quality of life and health for older adults. As the population ages, there is a growing cohort of kinless older adults without living partners or children, particularly among disadvantaged groups. Kinlessness has been associated with worse mental and physical health, significant unmet care needs, increased risk of dementia, higher rates of long-term placement, and higher mortality rates than those for patients with kin. Although other markers of social health have been studied in patients with heart failure, little is known about kinlessness in this population of patients. This review outlines the data on kinlessness and its impact on patients' outcomes, and it proposes novel interventions to mitigate its effects.

Stress-related gene regulation: Do isolated and connected individuals differ?

BACKGROUND

Social isolation and loneliness (known as social disconnection, collectively) lead to serious downstream health effects, including shortening of lifespan and higher risk for cardiac disease. We must better understand how isolation and loneliness lead to these negative health outcomes. Previous literature has demonstrated that social motivation and social ability are contributors to the likelihood of social isolation and loneliness. We examined the effect of the above social factors on immune gene expression in socially-connected and -isolated individuals.

METHODS

Recruitment occurred via two online advertisements, one for socially isolated individuals and another for general research participants. Participants (n = 102) were separated into groups (isolated versus connected) based on which ad they responded to, and provided data on isolation, loneliness, social motivation, and social ability. The Conserved Transcriptional Response to Adversity (CTRA) stress gene regulation program was assessed with genome-wide transcriptional profiling.

RESULTS

CTRA gene expression patterns were reversed between connected and isolated groups across several variables. Social isolation was associated with higher CTRA levels in the connected group, but lower levels in the isolated group. Social approach was associated with lower CTRA levels in the connected group, but higher in the isolated group, and the converse was true for social avoidance. CTRA levels were minimally affected by social ability measures.

CONCLUSION

Prior work on social isolation and loneliness has focused on loneliness and has identified many negative downstream health effects. In this study we demonstrate that objective social isolation may not be associated with the same negative downstream health effects, and in fact, social interaction may be more stressful than social isolation for some socially-isolated individuals.

Social Isolation, Loneliness, and Depressive Symptoms Among Older Adults: The Moderating Effect of Resilience

BACKGROUND AND OBJECTIVES

Social isolation has been recognized as a social problem with negative health consequences. Using data from 3 waves of the Health and Retirement Study, this study aimed to examine the long-term impact of social isolation on loneliness and depressive symptoms and to explore the moderating effect of resilience.

RESEARCH DESIGN AND METHODS

This study comprised 3,681 U.S. adults aged 60 and older at the baseline wave. Social isolation index was constructed using 5 indicators, including not married or cohabitating with a partner, no social participation, and less than monthly contacts with children, family members, or friends. Loneliness was measured by the University of California Los Angeles (UCLA) Loneliness Scale and depressive symptoms were measured by the Center for Epidemiological Studies-Depression scale. The moderator of resilience was assessed by the simplified resilience score. Latent growth curve models with robust standard errors were estimated.

RESULTS

The results of latent growth curve models showed that social isolation was significantly associated with more initial loneliness and depressive symptoms. However, social isolation was associated with a slower increasing rate of loneliness, but no significant relationship with the change rate of depressive symptoms. Furthermore, resilience significantly buffered the negative effect of social isolation on the initial level of depressive symptoms.

DISCUSSION AND IMPLICATIONS

The findings underscore the importance of enacting strategies and interventions targeting resilience to address social isolation and its negative consequences among older adults.

Loneliness and global cognitive functioning in racially and ethnically diverse US midlife and older adults

Introduction

Few studies have examined the association of loneliness and cognitive functioning in the US. We used two common measures of loneliness and examined their association in a large sample of US Black, Latino, and White adults (ages ≥ 50).

Methods

We analyzed Wave 3 of the National Social Life, Health, and Aging Project (N = 2,757). We examined loneliness using one item from the CES-D and the Felt Loneliness Measure (NFLM); cognitive functioning was assessed using the Montreal Cognitive Assessment (MoCA) tool, where higher scores indicated better functioning. We used weighted ordinary least squares regressions to examine the effects of loneliness (CES-D loneliness and NFLM in separate models) on MoCA scores. In exploratory analyses, we examined if these relationships varied by race and ethnicity. We adjusted all models for sociodemographic and other salient factors (e.g., chronic disease, depressive symptoms, living alone).

Results

Mean age was 63.49 years, 52% were female, and 9% were Black and 6% Latino persons. Approximately 54% endorsed feeling lonely on at least one measure; 31% (CES-D) and 46% (NFLM). The relationship between loneliness measures was positive and significant, X 2 (1, N = 2,757) = 435.493 p < 0.001. However, only 40% of lonely individuals were identified as lonely on both assessments. CES-D loneliness was inversely (βˆ = -0.274, p = 0.032) associated with MoCA scores and this association did not vary by race and ethnicity. Greater NFLM loneliness was positively associated (βˆ = 0.445, p < 0.001) with higher MoCA scores for Latino participants only.

Discussion

Loneliness appears to be an important predictor of cognitive functioning. However, the association of loneliness and cognitive functioning varied when using the CES-D loneliness item or the NFLM. Future work is needed to understand how loneliness and its clinically relevant dimensions (social, emotional, existential, chronicity) relate to global and individual cognitive domains. Research is needed with racially and ethnically diverse midlife and older adults, particularly to understand our counterintuitive finding for Latino participants. Finally, findings also support the need for research on interventions to prevent cognitive decline targeting loneliness.

Five Dimensions of Needs for Help: The Efficacy of a Technology-Based Intervention Among Asian American Breast Cancer Survivors

Cancer survivors including Asian American breast cancer survivors have reported their high needs for help during their survivorship process. With the COVID-19 pandemic, the necessity of technology-based programs to address their needs for help without face-to-face interactions has been highlighted. The purpose of this randomized intervention study was to determine the efficacy of a technology-based program in reducing various types of needs for help among this specific population. This was a randomized clinical trial with repeated measures. A total of 199 participants were included in the data analysis. The recruitment settings included both online and offline communities/groups for Asian Americans. The needs for help were assessed using the Support Care Needs Survey-34 Short Form (SCNS) subscales measuring psychological, information, physical, support, and communication needs. Data analysis was conducted through an intent-to-treat approach. In the mixed effect models, psychological needs, information needs, physical needs, and communication needs decreased over time (P < .001). However, there were no significant group * time effects. Social support significantly mediated the effects of a technology-based intervention on psychological, information, and support needs at the pre-test and the post-1 month. This study supported significant decreases in the needs for help of Asian American breast cancer survivors by a technology-based intervention. Further studies are needed with other racial/ethnic groups of cancer survivors to confirm the efficacy of a technology-based intervention in reducing cancer survivors' needs for help during their survivorship process.

Community support, social isolation and older adults' life satisfaction: evidence from a national survey in China

OBJECTIVES

Despite the recognized importance of community social service and community built facility for enhancing older adults' life satisfaction, the mechanisms underlying their relationship have not been thoroughly examined. This study aims to complement the existing knowledge by investigating the mediating role of social disconnectedness and loneliness in the association between community support and life satisfaction among older adults.

METHODS

Using data from the 2018 China Longitudinal Aging Social Survey, the study analyzes responses from 9,874 Chinese older adults (mean age = 71.30 years, SD = 7.30). We conducted descriptive statistics and Pearson's correlation to explore the variables. This study also used Mplus 8.0 to conduct a path analysis model that evaluated both the direct and indirect effects of community social service and built facility on life satisfaction. Social disconnectedness and loneliness were included as mediating variables in this model.

RESULTS

The present study results show that both community social service and community built facility are positively associated with life satisfaction among older adults, and community social service is more imporatant for enhancing the life satisfaction. In addition, these associations are mediated by social disconnectedness and loneliness.

CONCLUSION

Our research suggests that strengthening community social service programs and improving the built environment can reduce social disconnectedness and loneliness among older adults, ultimately enhancing their life satisfaction. Specifically, policymakers can invest in targeted interventions to enhance social connectedness and reduce loneliness, with the goal of improving the overall well-being of older adults.

Fraud victimization across the lifespan: evidence on repeat victimization using perpetrator data

Older adults are thought to be more susceptible to scams, yet understanding the relationship between chronological age and victimization is limited by underreporting. This study avoids underreporting bias by merging four longitudinal databases of Americans (N = 1.33 million) who paid money in response to mail scams over 20 years. We investigate the risk of repeat victimization and victimization by multiple scam types over the life course. Victims in their 70s and 80s are 9% more likely to experience another victimization incident than those in their 50s. Those age 18 to 29 are 24% less likely to experience another victimization incident. Relative to adults in their 50s, the odds of victimization by multiple scams are greater for those in their 60s and 70s, but lower for those 80 + . This study demonstrates the research potential in using scammers' data to understand patterns of victimization. Fraud prevention efforts should target older individuals who are at higher risk of repeat victimization and suffer greater losses as a result.

Rural-urban differences in older adults' life satisfaction and its determining factors

Although determinants of life satisfaction in older adults have been well documented, research has to date failed to fully address the experience of older adults living in places with different levels of urbanization. Furthermore, there are conflictive findings regarding the type of residence environment that offers the greatest benefits for the wellbeing of older adults. Our study proposes an integrative research model to determine the nature of the relationships between loneliness, self-esteem and life satisfaction, with a particular focus on the living environment (rural-urban) of the older adults. Using a cross-sectional survey design volunteers (aged 60+) from rural (n = 198) and urban (n = 198) in Galicia (Spain) completed a questionnaire. Structural Equation Modelling (SEM) was used to test the relationships between loneliness, self-esteem and life satisfaction and multigroup analysis was performed to analyse the existence of differences in the relationships based on the area of residence of older adults. We found that higher levels of loneliness were a significant predictor of reduced life satisfaction and reduced self-esteem. Self-esteem not only increases life satisfaction, but also reduces the negative impact loneliness may have on it. Where the older adults lived had a significant effect on the relationships between loneliness, self-esteem and life satisfaction. The relationships were stronger for older adults living in urban areas. Differentiated policy initiatives should be considered, depending on the area of residence in order to increase the life satisfaction of older adults.

Perceived Community Belonging as a Moderator: Effects of Childhood Abuse on Health and Well-Being Among Middle-Aged and Older Canadians

This study examined the moderating role of perceived community belonging in the relationship between childhood abuse and health and well-being outcomes among Canadian individuals aged 55 and older. Using data from the 2014 Canadian General Social Survey (n = 14,416), multiple linear regression models revealed that women who experienced either childhood physical or sexual abuse reported poorer self-rated general and mental health, as well as lower life satisfaction, compared to those without such histories. The most pronounced effects were observed among women who experienced both types of abuse. For men, a similar pattern was evident only for those who experienced childhood physical abuse. Notably, among women, a strong sense of community belonging lessened the negative effects of both types of childhood abuse on all examined outcomes. These findings underscore the protective role of perceived community belonging against the consequences of childhood abuse for older women. They illuminate the crucial role of gerontological social workers and scholars in promoting community integration and support. Focusing on these areas, especially for those with traumatic histories, can potentially improve their overall health and well-being.

The Benefits of Technology for Engaging Aging Adults: Findings From the PRISM 2.0 Trial

Background and Objectives

Technology has potential for providing support for aging adults. This study evaluated the Personal Reminder Information and Social Management 2.0 (PRISM 2.0) software, in terms of enhancing social engagement and quality of life, and decreasing loneliness among older adults.

Research Design and Methods

The randomized field trial conducted in diverse living contexts (rural locations, senior housing, and assisted living communities [ALC]). Two hundred and forty-five adults, aged 64 to 99 years, were randomly assigned to the PRISM 2.0 (integrated software system designed for aging through an iterative design process) or a Standard Tablet (without PRISM) Control condition, where participants received the same amount of contact and training as those in the PRISM 2.0 condition. Primary outcomes included measures of loneliness, social support, social connectedness, and quality of life. Secondary outcomes included measures of social isolation, mobile device proficiency, and technology readiness. Data were collected at baseline and 6 and 9 months postrandomization. This article focuses on the 6-month outcomes due to coronavirus disease 2019-related data challenges at 9 months.

Results

Contrary to our hypothesis, participants in rural locations and senior housing in both conditions reported less loneliness and social isolation, and greater social support and quality of life at 6 months, and an increase in mobile device proficiency. Participants in the ALCs in both conditions also evidenced an increase in mobile device proficiency. Improvements in quality of life and health-related quality of life were associated with decreases in loneliness.

Discussion and Implications

This study provides compelling evidence about the benefits of technology for older adults in terms of enhancing social outcomes and quality of life. However, the findings also underscore that for technology applications to be successful, they need to be adapted to the abilities and needs of the user group and instructional support needs to be provided.

Social interaction level modulates the impact of frailty on cognitive decline: a longitudinal study

OBJECTIVES

This study evaluates whether social interaction level modifies the association between frailty and cognitive decline in older adults.

METHODS

A total of 2701 adults aged ≥65 years enrolled in the Progetto Veneto Anziani (Pro.V.A.), participated in the study. At baseline, participants were classified as having low, moderate, or high social interactions based on: cohabiting status, frequency of contacts with relatives/friends or involvement in childcare activities, and frequency of participation in social or community activities. Baseline frailty was defined as the presence of ≥3 criteria among: weight loss, weakness, slowness, low physical activity, and exhaustion. Cognitive function was assessed through the Mini-Mental State Examination (MMSE) at baseline and after 4.4 and 7 years. The association between frailty and MMSE changes over time was evaluated through linear mixed models. Interaction and subgroup analyses explored the modifying effect of social interaction level on the above association.

RESULTS

The mean age of participants was 76.1 years, and 59.1% were women. Frail individuals had a steeper annual MMSE decline than their non-frail counterparts (ß=-0.40, 95%CI: -0.59, -0.20). When stratifying participants by social interaction level, we found that the association between frailty and MMSE changes over time was stronger in those with low social interactions (ß=-0.74, 95%CI: -1.33, -0.15) while attenuated in those with moderate (ß=-0.42, 95%CI: -0.74, -0.11) or high social interaction level (ß=-0.29, 95%CI: -0.58, 0.01).

CONCLUSION

Maintaining frequent social interactions might mitigate the negative impact of frailty on older people's cognitive functions.

Social isolation and depression as risk factors for weight loss of 5kg or more among older Korean adults

Given a well-known overlapping prevalence of social isolation with loneliness and depression among older adults, this study aimed to contextually investigate the relationship of these constructs with weight loss of more than 5kg in a year, with a special focus on the intersection of living alone and marital dissolution as key dimensions of isolation. The data were obtained from the Korean Longitudinal Study of Aging (KLoSA) from 2006, 2008, 2010, 2012, 2014, 2016, and 2018, with an adult sample of those aged 65 and older (n = 5,481). The study evaluated several critical dimensions of social isolation: living alone, transition to living alone, infrequent social contact with children or friends, and infrequent social participation. These dimensions were examined individually and as a composite scale, along with loneliness and depressive symptoms, to determine their association with weight loss of 5kg or greater among older men and women. Generalized Estimating Equation (GEE) regression models enabled investigation of whether socially isolated men and women tended to lose 5kg or more in weight, given other confounding factors. Surprisingly, the results showed no evidence of such a trend. However, significant associations were found between weight loss and changes in living alone and marital status. For older men, transitioning to living alone without a change in marital status was linked to significant weight loss. For older women, transitioning to living alone following widowhood or divorce was the risk factor. These relationships remained significant even after adjusting for depression and a wide range of covariates. Additional analysis testing a cumulative effect revealed that only depression was a risk factor for being underweight at the last observation. Therefore, to prevent a clinically risky extent of weight loss, health policies for older Koreans should focus on those who transition to living alone, especially due to spousal bereavement or divorce (among women) and separation from living with children (among men).

Associations between social networks, cognitive function, and quality of life among older adults in long-term care

BACKGROUND

Having rich social networks is associated with better physical and cognitive health, however older adults entering long-term care may experience an increased risk of social isolation and consequent negative impacts on cognitive function. Our study aimed to identify if there is an association between accessing specific types of services or activities within long-term care on social networks and cognition.

METHODS

A cross-sectional study of 96 residents from 2 aged care providers in New South Wales, Australia. Residents were given a battery of assessments measuring social network structure (Lubben Social Network Scale, LSNS-12), quality of life (EuroQol 5D, Eq. 5D5L) and cognitive function (Montreal Cognitive Assessment, MoCA). Demographic factors and service use factors were also collected from aged care providers' electronic records. Independent sample t-test, ANOVA and linear regression analyses were used to explore associated factors for cognition.

RESULTS

Residents had a mean age of 82.7 ± 9.4 years (median = 81) and 64.6% were women. Most residents had cognitive impairment (70.8%) and reported moderate sized social networks (26.7/60) (Lubben Social Network Scale, LSNS-12). Residents who had larger social networks of both family and friends had significantly better cognitive performance. Service type and frequency of attendance were not associated with cognitive function.

CONCLUSIONS

Among individuals most at risk of social isolation, having supportive and fulfilling social networks was associated with preserved cognitive function. The relationship between service provision and social interactions that offer psychosocial support within long-term facilities and its impact over time on cognitive function requires further exploration.

Trends in the prevalence of social isolation among middle and older adults in China from 2011 to 2018: the China Health and Retirement Longitudinal Study

BACKGROUND

Epidemiological studies have shown that social isolation, which is prevalent in older adults, is associated with a range of adverse health outcomes, but the prevalence of and trends in regard to social isolation remain ambiguous in China. The aim of this study was to elucidate the trends regarding the prevalence of social isolation among middle-aged and older adults in China from 2011 to 2018 and to further identify associated risk factors.

METHODS

A repeated cross-sectional study, The data were derived from panel sample data of four waves conducted from May 2011 to August 2018 in the nationally representative China Health and Retirement Longitudinal Study (CHARLS) using multistage probability sampling. Social isolation was ascertained by the five item Steptoe Social Isolation Index. The potential covariates were demographic characteristics, lifestyle factors, and health status. Linear-by-linear association was used to assess the trends in regard to social isolation over time under the influence of the potential covariates. Linear-by-linear association and an age-period-cohort analysis were used to explore the trends, and two-level (time, individual) generalized estimating equation models (GEE) linked multivariate binary logistic regression were performed to identify risk factors.

RESULTS

A high prevalence of social isolation and a moderate upward trend from 2013 to 2018 were observed among a U-shaped trend prevalence of social isolation from 2011 to 2018 across China, with rates of 38.09% (95% CI = 36.73-39.45) in 2011, 33.66% (32.32-35.00) in 2013, 39.13% (37.59-40.67) in 2015, and 39.95% (38.59-41.31) in 2018 (p < 0.001). The prevalence of social isolation increased with age and educational attainment. Females had a higher prevalence than males. The prevalence of social isolation was found to be significantly lower in pensioners than in non-pensioners between 2011 and 2018 (p < 0.001). The prevalence of social isolation was 38.9%, 34.9%, 38.5%, and 44.08% about three times higher among those who doid not use the Internet and 13.44%, 11.64%, 12.93%, and 16.73% than among those who doid in 2011, 2013, 2015 and 2018 respectively. The participants with short (0-5 h) and long sleep (9 or more hours), and poor self-rated health had a higher prevalence of social isolation than the others. Older age, lower educational attainment, living in a rural region, lack of medical insurance or pension, lack of internet use and poor health were risk factors (p < 0.05).

CONCLUSIONS

We found a U-shaped prevalence of social isolation trends from 2011 to 2018 and revealed increasing trends from 2013 to 2018 among middle-aged and older adults in China. The findings of the study highlight the urgent need for interventions to reduce social isolation including improving sleep quality and internet skills. Disadvantaged groups in terms of age, economic status, and health status should be the focus of such interventions, especially in the era of COVID-19.

Relationship of Living and Eating Arrangements to Mental Distress Among Older Korean Immigrants: Gender Difference in the Mediating Role of Loneliness

This study examined how different living/eating arrangements were associated with loneliness and depressive symptoms among older Korean immigrants. We examined gender differences considering: (1) patterns of living/eating arrangements and their relations with loneliness and mental distress and (2) indirect effect of living/eating arrangements on mental distress through feeling lonely. Data were drawn from the Study of Older Korean Americans that surveyed older; Korean immigrants during 2017-2018 (N = 2150). Living/eating arrangements were classified in the combination of four categores. Using the PROCESS macro, we tested gender differences in the mediation effect of loneliness on the relationship between living/eating arrangements and mental distress while controlling for background/health characteristics and social connectedness-related variables. The mediating role of loneliness was manifested differentially between men and women. By administering simple measures of living/eating arrangements, practitioners could potentially identify key targets to improve social and mental well-being, particularly among older immigrants with limited resources.

Information and Communication Technology for Managing Social Isolation and Loneliness Among People Living With Parkinson Disease: Qualitative Study of Barriers and Facilitators

BACKGROUND

Parkinson disease (PD) is a complex, noncurable, and progressive neurological disease affecting different areas of the human nervous system. PD is associated with both motor and nonmotor symptoms, which negatively affect patients' quality of life and may cause changes in socialization such as intentional social withdrawal. This may further lead to social isolation and loneliness. The use of information and communication technology (ICT) plays an important role in managing social isolation and loneliness. Currently, there is a lack of research focusing on designing and developing ICT solutions that specifically address social isolation and loneliness among people living with PD.

OBJECTIVE

This study addresses this gap by investigating barriers and social needs in the context of social isolation, loneliness, and technology use among people living with PD. The insights gained can inform the development of effective ICT solutions, which can address social isolation and loneliness and improve the quality of life for people living with PD.

METHODS

A qualitative study with 2 phases of data collection were conducted. During the first phase, 9 health care professionals and 16 people living with PD were interviewed to understand how PD affects social life and technology use. During the second phase, 2 focus groups were conducted with 4 people living with PD in each group to gather insights into their needs and identify ways to manage social isolation and loneliness. Thematic analysis was used to analyze both data sets and identify key themes.

RESULTS

The results showed that the barriers experienced by people living with PD due to PD such as "fatigue," "psychological conditions," "social stigma," and "medication side effects" affect their social life. People living with PD also experience difficulties using a keyboard and mouse, remembering passwords, and navigating complex applications due to their PD-related physical and cognitive limitations. To manage their social isolation and loneliness, people living with PD suggested having a simple and easy-to-use solution, allowing them to participate in a digital community based on their interests, communicate with others, and receive recommendations for social events.

CONCLUSIONS

The new ICT solutions focusing on social isolation and loneliness among people living with PD should consider the barriers restricting user's social activities and technology use. Given the wide range of needs and barriers experienced by people living with PD, it is more suitable to adopt user-centered design approaches that emphasize the active participation of end users in the design process. Importantly, any ICT solution designed for people living with PD should not encourage internet addiction, which will further contribute to the person's withdrawal from society.

Does cognitive impairment moderate the relationship between social isolation and anxiety? A 5-year longitudinal study of a nationally representative sample of community residing older adults

BACKGROUND

Anxiety is common in older adults and social isolation is one of the leading factors associated with their anxiety. However, what is unknown is how the relationship between social isolation and anxiety differs by cognitive status. Therefore, this study was conducted to (1) compare the level of social isolation and anxiety in older adults who developed probable dementia and mild cognitive impairment (MCI) to those who maintained normal cognitive function over 5 years; and (2) determine if cognitive impairment moderates the relationship between changes in social isolation and changes in anxiety over 5 years.

METHODS

A secondary data analysis was conducted using the National Social Life, Health, and Aging Project (NSHAP): Wave 2 (2010-2011) and Wave 3 (2015-2016). The participants were categorized into three groups: Participants who developed probable dementia over 5 years (4.3%), developed probable MCI (19.1%), or maintained normal cognitive function (76.6%). Weighted linear regression analyses with a group interaction were used to examine the moderating effect of cognitive impairment on the relationship between changes in social isolation and anxiety.

RESULTS

At the 5-year follow up, there were statistically significant differences in social isolation between the three groups (p = 0.043). Regression analyses showed that increased social isolation over time was related to increased anxiety over 5 years regardless of cognitive status after controlling for covariates (p = 0.017).

CONCLUSIONS

The relationship between social isolation and anxiety was a universal phenomenon regardless of cognitive status. Tailored interventions targeting both people with or without cognitive impairment are needed to lessen social isolation and anxiety.

Social Isolation, Self-Rated Health, and Self-Rated Oral Health among African Americans

Social isolation is associated with worse health; however, few studies have examined the health effects of isolation among African Americans. The purpose of this study is to evaluate associations between social isolation and self-rated physical and oral health from the National Survey of American Life, a nationally representative sample of African Americans. Social isolation was operationalized to reflect both objective isolation (lack of contact) and subjective isolation (lack of emotional closeness). Self-rated physical and oral health were regressed on objective and subjective isolation while controlling for marital status, gender, age, family income, education, and health behaviors. Poorer self-rated physical health was associated with objective isolation, while poorer self-rated oral health was associated with subjective isolation. This study contributes to the small literature of the impact of social isolation on health among African Americans; furthermore, it is the first to examine the relationship between isolation and self-rated oral health in this population.

Online mindfulness training for older adults during the COVID-19 pandemic: a randomized controlled trial using a multi-method assessment approach

OBJECTIVES

The COVID-19 pandemic drastically accelerated the need for studies examining the effectiveness of programs to bolster psychological well-being, particularly for at-risk groups, such as older adults (OAs). Mindfulness Training (MT) has been suggested as a well-suited program for this purpose. The present study examined the impact of a 4-week online, trainer-led MT course tailored for OAs during the early months of the COVID-19 pandemic.

METHODS

Fifty-three OAs were randomly assigned to either Group A or Group B. Group A received the online MT course during the 4-week interval between the first (T1) and second (T2) testing sessions, while Group B received the same MT course during the interval between T2 and the third testing session (T3). The testing sessions included measures of mindfulness, emotional well-being, psychological health, and cognitive performance. In addition, a very brief survey was sent every week during the T1-T2 and T2-T3 intervals to assess weekly emotional well-being.

RESULTS

The findings revealed that MT may improve some, albeit not all, aspects of mindfulness and well-being, while no significant results were noted for outcomes measuring psychological health and cognitive performance.

CONCLUSIONS

These findings are discussed in the context of the evolving COVID-19 situation.

The combined impact of social networks and connectedness on anxiety, stress, and depression during COVID-19 quarantine: a retrospective observational study

Introduction

The COVID-19 pandemic and associated quarantine measures have precipitated a surge in mental health disorders, particularly depression and anxiety. Government policies and restrictions on physical activity have contributed to this phenomenon, as well as diminished subjective social connectedness and exacerbated objective social isolation. As two dimensions of social isolation, it is worth noting that subjectively perceived social connectedness serves as a protective factor for mental health, whereas the decline in the size of objectively evaluated social networks poses a significant risk. However, research investigating the combined influence of these two dimensions remains limited.

Methods

This study used an online survey to collect data to investigate the effects of objective social connectedness and objective social networks on anxiety, stress, and depression during COVID-19 quarantine. A total of 485 participants were analyzed using statistical methods, including paired t-test, Pearson correlation analysis, linear regression, cluster analysis, ANOVA, and moderated mediated.

Results

The study found that anxiety and depression scores increased during the quarantine, with age, education, and social connectedness scores associated with the increase. Pre-quarantine anxiety and depression levels were strongly correlated with mental health status during quarantine. Cluster analysis, respectively, revealed three clusters for those without increasing anxiety and depression scores. The study also found that objective social network influences the impact of subjective social connectedness on pre-quarantine mental health, which in turn affects anxiety and depression levels during quarantine.

Conclusion

The study identified that quarantine increased anxiety and depression, with age being protective, and education and subjective social connectedness as risk factors. The study also emphasizes the comprehensive impact of objective and subjective social isolation. Although individuals perceive the same degree of social connectedness, those with smaller social networks are more prone to developing symptoms of anxiety and depression, which are also more likely to worsen during quarantine.

Associations between social isolation and diet quality among US adults with disability participating in the National Health and Nutrition Examination Survey, 2013-2018

Social isolation and disability are established risk factors for poor nutrition. We aimed to assess whether social isolation is associated with diet quality specifically among adults with disabilities. This cross-sectional analysis used data from the National Health and Nutrition Examination Survey, 2013-2018. Adults with a disability, who were not pregnant, breastfeeding, or missing dietary intake data were included (n = 5,167). Disability was defined as a physical functioning limitation based on difficulty with any activities of daily living, instrumental activities of daily living, lower extremity mobility activities, or general physical activities. The Healthy Eating Index (HEI)-2015 measured diet quality; higher scores correspond to higher diet quality. We computed a social isolation index by summing single status, living alone, and two social engagement difficulty measures (one point for each component met; maximum 4 points). Multivariable linear regression, controlling for demographic and health covariates, estimated differences in HEI scores for dietary intake data, by social isolation score. Over half of HEI scores were < 51, corresponding to "poor" diet quality. Higher social isolation score was associated with lower vegetable and seafood/plant proteins intake. Single status and one of two social engagement measures were associated with lower scores on certain adequacy components. Differences were modest. There was little evidence of effect modification by age or gender. Adults with disabilities are not meeting national dietary standards; improving diet quality is a priority. Whether social isolation is associated with specific dietary components in this population requires further investigation. Further research is also needed among younger adults.

A Decision Tree Analysis on Symptom Experience of Asian American Breast Cancer Survivors

BACKGROUND

Mainly due to their cultural attitudes toward symptoms and breast cancer, Asian American breast cancer survivors tend to suffer from symptoms and often delay in getting treatments, information, and support. To improve their symptom management, it would be important to determine risk groups among them. Decision tree analyses reportedly help determine risk groups by identifying the characteristics that are directly associated with target health outcomes.

OBJECTIVE

Using a decision tree analysis, this study aimed at identifying the characteristics that were closely linked to the symptom experience of Asian American breast cancer survivors.

METHODS

This was a part of a parent randomized controlled trial among Asian American breast cancer survivors. Only the data from 135 women at the pre-test were included. Multiple instruments were used to collect the data: the Memorial Symptom Assessment Scale-Short Form, the Cancer Behavior Inventory, the PRQ-2000, the Perceived Isolation Scale, and the Supportive Care Needs Survey-Short Form 34. The data were analyzed using latent profile analysis and decision tree analyses.

RESULTS

Two most frequently found profiles included the low symptom experience profile (72.6%) and the high symptom experience profile (27.4%). The high symptom experience profile was predicted by 2 combined characteristics; (a) high psychological needs for help (over 60.00 points), and (b) low psychological needs for help (cut point = 60.00), high perceived barriers (cut point = 1.62), and high social isolation (social support) (cut point = 2.33).

CONCLUSIONS

These characteristics linked to Asian American breast cancer survivors with high symptom experience need to be considered in future intervention development.

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.

Examining sociocultural factors in widowhood and cognitive function among older Chinese immigrants: findings from the PINE study

Objectives: Although there is growing evidence on widowhood and cognitive function, existing studies have shown mixed results. Little is known about protective factors that may contribute to resilience, thereby ameliorate the adverse effect of widowhood on cognition among older Asian immigrants. This study explored potential moderators (i.e. social support, acculturation, leisure activities) in the association between widowhood and cognitive function among older Chinese immigrants.Method: The study sample included 2,515 adults aged 60 or older who completed two waves (2011-2013 and 2013-2015) of the Population Study of Chinese Elderly in Chicago. Cognitive function was indexed by global cognitive function and episodic memory. Linear regression analyses were conducted with interaction terms.Results: Our results show that social support moderated the relationship between widowhood and global cognitive function, and acculturation moderated the relationship between widowhood and episodic memory. The adverse effect of widowhood on cognitive function was more pronounced at lower levels of social support and acculturation.Conclusion: Our findings indicate buffering roles of social support and acculturation in cognitive health among older Chinese immigrants who experience widowhood. Providing supportive programs and interventions to increase social support and acculturation is suggested to promote cognitive function in this population.

Loneliness Is Associated With Lower Self- and Clinician-Rated Levels of Personality Functioning

Personality disorders (PDs) are associated with interpersonal dysfunction, loneliness, and reduced social embeddedness. This study investigates loneliness and social network size in association with self- and clinician-rated personality functioning regarding the DSM-5's Alternative Model for Personality Disorders (AMPD). Eighty psychiatric inpatients including participants with and without PDs completed the Semi-structured Interview for Personality Functioning, the Level of Personality Functioning Scale - Brief Form, the UCLA Loneliness Scale, and the Social Network Index. Patients with PDs reported more loneliness and personality dysfunctioning than patients without PDs. Social network size did not differ between patient groups and showed lower correlations with personality functioning compared to loneliness. Loneliness was further associated with deficits in personality functioning. Deficits in distinct AMPD domains and loneliness may constitute transdiagnostically relevant factors that are related and mutually reinforcing. This could be important for identifying patients beyond PD diagnoses who are at risk of poor psychosocial functioning and require tailored psychotherapy.

The relationship of social isolation and sleep in older adults: evidence from cross-sectional and longitudinal studies

OBJECTIVES

This study aimed to explore the relationship between social isolation and sleep in later life and the role of loneliness in this relationship.

METHODS

In Study 1, we conducted a cross-sectional analysis of the correlation between social isolation and sleep in community-dwelling older adults (N = 108). This relationship was assessed using subjective and objective measures. Moreover, we examined the mediating role of loneliness cross-sectionally (Study 1) and longitudinally (Study 2). Longitudinal study was based on three waves of data from the National Scale Life, Health, and Aging Project (N = 1, 554).

RESULTS

The results showed that social isolation was robustly associated with sleep in the general population of older adults. Specifically, subjective social isolation was associated with subjective sleep, and objective social isolation was associated with objective sleep. The results of the longitudinal study showed that loneliness mediated the reciprocal link between social isolation and sleep across time after controlling for autoregressive effects and basic demographics.

CONCLUSIONS

These findings address the gap in the literature on the link between social isolation and sleep in older adults, extending the understanding of improvement in older adults' social networks, sleep quality, and psychological well-being.

Perceived Social Support and Sustained Physical Activity During the COVID-19 Pandemic

BACKGROUND

COVID-19 lockdown introduced substantial barriers to physical activity, providing a unique 'natural experiment' to understand the social factors associated with sustained physical activity. The objectives of this study were to identify the proportion of people who successfully sustained physical activity during lockdown and to explore whether social support, loneliness and social isolation were associated with maintenance of physical activity during COVID-19 lockdown.

METHOD

Longitudinal data from 16,980 participants, mean age 51.3 years (SD = 14.3) from the COVID-19 Social Study was used to identify a sample of participants who maintained their physical activity despite lockdown.

RESULTS

Seventeen percent were consistently active whilst 42% were completely inactive. After adjustment for multiple confounders, high social support was associated with a 64% (95% CI 50-80%) increased odds of sustaining physical activity and medium social support was associated with 32% (95% CI 20-44%) increased odds. Associations between physical activity and loneliness and social isolation were not found.

CONCLUSION

This study supports previous research showing the importance of social support for the long-term maintenance of physical activity behaviour but shows that such effects extend to contexts of social restrictions.

Social Withdrawal, Loneliness, and Health in Schizophrenia: Psychological and Neural Mechanisms

BACKGROUND AND HYPOTHESIS

Some of the most debilitating aspects of schizophrenia and other serious mental illnesses (SMI) are the impairments in social perception, motivation, and behavior that frequently accompany these conditions. These impairments may ultimately lead to chronic social disconnection (ie, social withdrawal, objective isolation, and perceived social isolation or loneliness), which may contribute to the poor cardiometabolic health and early mortality commonly observed in SMI. However, the psychological and neurobiological mechanisms underlying relationships between impairments in social perception and motivation and social isolation and loneliness in SMI remain incompletely understood.

STUDY DESIGN

A narrative, selective review of studies on social withdrawal, isolation, loneliness, and health in SMI.

STUDY RESULTS

We describe some of what is known and hypothesized about the psychological and neurobiological mechanisms of social disconnection in the general population, and how these mechanisms may contribute to social isolation and loneliness, and their consequences, in individuals with SMI.

CONCLUSIONS

A synthesis of evolutionary and cognitive theories with the "social homeostasis" model of social isolation and loneliness represents one testable framework for understanding the dynamic cognitive and biological correlates, as well as the health consequences, of social disconnection in SMI. The development of such an understanding may provide the basis for novel approaches for preventing or treating both functional disability and poor physical health that diminish the quality and length of life for many individuals with these conditions.

Later-life depressive symptoms during the Covid-19 pandemic: Investigations of individual, cumulative, and synergistic effects of social isolation

OBJECTIVES

This study examines associations between social isolation and depressive symptoms among Hong Kong Chinese adults aged 65 and older by investigating the distinct effects of individual indicators, cumulative index, and typologies of social isolation during the Covid-19 pandemic.

METHODS

We used a sample of 260 older adults from a cross-sectional, city-wide online survey targeting 1,109 aged 45+ adults through purposive sampling. Seven indicators of social isolation (not married; living alone; not engaging in social/organizational activities; no social contact with friends or families; lack of family and friends networks; loneliness) using Cornwell & Waite's framework were selected to construct three unique types of social isolation measures. We used latent class analysis (LCA) and regression models to examine the effects of varied typologies of social isolation on depressive symptoms.

RESULTS

Individual model of social isolation showed that lack of social contact and feeling lonely were significant predictors of depressive symptoms. A strong linear-trend gradient effect of cumulative social isolation on depressive symptoms was also observed. The LCA model identified four typologies of social isolation (socially isolated; living alone but socially engaged; married but lacking social ties, and not socially isolated); those in the 'socially isolated' and 'married but lacking social ties' groups had the most depressive symptoms.

CONCLUSION

Three operationalizations of social isolation demonstrated different utilities and implications in assessing the impacts of social isolation on depressive symptoms. Social contacts and loneliness, rather than living status or other characteristics of isolation, were the factors most strongly associated with depressive symptoms. Support programs should target lonely older adults who lack social engagement opportunities, as they are at increased risk of depression.

Retention and Overdose Risk among Patients Receiving Substance Use Disorder Treatment, Mental Health Care and Peer Recovery Support: A Longitudinal Analysis

BACKGROUND

Drug overdose remains a major crisis in the United States. Expanding substance use disorder (SUD) treatment and recovery support services is critical for reducing overdose risk during disasters such as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2) pandemic. We evaluated the outcomes of an innovative multicomponent service, inclusive of medications for SUD, and peer support, colocated in an outpatient infectious disease clinic in Baltimore City. Our goal was to examine whether a multicomponent SUD program can support patients in recovery during a pandemic.

METHODS

One hundred five patients in the RESTORE service between 2019-2020 completed baseline, 3-month, and 6-month surveys. Telemedicine and phone-based support groups were implemented in March 2020 after statewide restrictions on face-to-face services due to SARS-CoV2. Data from surveys and electronic medical records were integrated and analyzed using mixed-effects regression models.

RESULTS

At baseline, most patients (88%) reported using drugs/alcohol in the preceding 30 days; 48% of patients reported a history of drug overdose, as well anxiety (23%) and depression (28%) symptoms. Despite pandemic-related disruptions and procedural changes, retention in RESTORE was high (83% after 3 months, 76% after 6 months). Mixed-effects regression models indicated decreased anxiety, alcohol use, heroin use, and nonfatal overdose after 6 months of enrollment (all P < 0.05).

CONCLUSIONS

Multicomponent SUD services that are colocated within infectious disease specialty services could help patients to successfully manage their overdose risk and mental health even during future disasters. This model of care could be implemented in other specialty settings that see high rates of SUD.

Association of Social Isolation With Hospitalization and Nursing Home Entry Among Community-Dwelling Older Adults

Importance

Social isolation is associated with adverse health outcomes, yet its implications for hospitalization and nursing home entry are not well understood.

Objective

To evaluate whether higher levels of social isolation are associated with overnight hospitalization, skilled nursing facility stays, and nursing home placement among a nationally representative sample of community-dwelling older adults after adjusting for key health and social characteristics, including loneliness and depressive symptoms.

Design, Setting, and Participants

This observational cohort study included 7 waves of longitudinal panel data from the Health and Retirement Study, with community-dwelling adults aged 65 years or older interviewed between March 1, 2006, and June 30, 2018 (11 517 respondents; 21 294 person-years). Data were analyzed from May 25, 2022, to May 4, 2023.

Main Outcomes and Measures

Social isolation was measured with a multidomain 6-item scale (range, 0-6, in which a higher score indicates greater isolation). Multivariate logistic regressions were performed on survey-weighted data to produce national estimates for the odds of self-reported hospitalization, skilled nursing facility stays, and nursing home placement over time.

Results

A total of 57% of this study's 11 517 participants were female, 43% were male, 8.4% were Black, 6.7% were Hispanic or Latino, 88.1% were White, 3.5% were other ("other" includes American Indian or Alaska Native, Asian or Pacific Islander, and other race, which has no further breakdown available because this variable was obtained directly from the Health and Retirement Study), and 58.2% were aged 65 to 74 years. Approximately 15% of community-dwelling older adults in the US experienced social isolation. Higher social isolation scores were significantly associated with increased odds of nursing home placement (odds ratio, 2.01; 95% CI, 1.21-3.32) and skilled nursing facility stays (odds ratio, 1.16; 95% CI, 1.06-1.28) during 2 years. With each point increase in an individual's social isolation score, the estimated probability of nursing home placement or a skilled nursing facility stay increased by 0.5 and 0.4 percentage points, respectively, during 2 years. Higher levels of social isolation were not associated with 2-year hospitalization rates.

Conclusions and Relevance

This cohort study found that social isolation was a significant risk factor for nursing home use among older adults. Efforts to deter or delay nursing home entry should seek to enhance social contact at home or in community settings. The design and assessment of interventions that optimize the social connections of older adults have the potential to improve their health trajectories and outcomes.

The Characteristics of Asian American Breast Cancer Survivors with Low Quality of Life: a Decision Tree Analysis

To provide appropriate and adequate information and support for Asian American breast cancer survivors, it would be essential to identify risk groups among them to target in future cancer education interventions. In this secondary analysis, the characteristics of risk groups within Asian American breast cancer survivors who had low quality of life were identified using a decision tree analysis. For this analysis, only the pre-test data of 185 women from a parent study were selected. Multiple instruments including the Functional Assessment of Cancer Therapy Scale-Breast Cancer (FACT-B) were used in the parent study. The data were analyzed using descriptive and inferential statistics and decision tree analyses. The decision tree analyses showed six combined characteristics associated with lower quality of life scores than the total mean quality of life scores. For instance, the women with lower quality of life scores (than the total mean quality of life scores) had high perceived barriers (cut point = 1.84), low self-efficacy for coping (cut point = 81.50), and high global symptom distress (cut point = 2.27). Also, the characteristics linked to the lowest quality life scores were different depending on the dimensions of the quality of life. The characteristics associated with the quality of life of Asian American breast cancer survivors need to be considered in future education programs for this specific population.

Social Isolation, Loneliness, and Cognitive Performance in Older Adults: Evidence From the ELSI-Brazil Study

BACKGROUND

The association between social isolation and cognitive performance has been less investigated in low-to-middle-income countries (LMIC) and the presence of depression as a moderator on this association has not been examined. The authors examined the associations of social isolation and perceived loneliness with cognitive performance in the Brazilian Longitudinal Study of Aging.

METHODS

In this cross-sectional analysis, social isolation was evaluated by a composite score including marital status, social contact, and social support. The dependent variable was global cognitive performance, which considered memory, verbal fluency, and temporal orientation tests. Linear and logistic regressions were adjusted for sociodemographic and clinical variables. The authors added interaction terms of depressive symptoms with social isolation and loneliness to examine whether depression, measured through the Center for Epidemiologic Studies-Depression Scale, modified these associations.

RESULTS

Among 6,986 participants (mean age = 62.1 ± 9.2 years), higher levels of social connections were associated with better global cognitive performance (B = 0.02, 95%CI: 0.02; 0.04). Perceived loneliness was associated with worse cognition (B = -0.26, 95%CI = -0.34; -0.18). Interactions of depressive symptoms with social connections scores were found on memory z-score and with loneliness on global and memory z-scores, suggesting a weaker association between social isolation or loneliness and cognition among those with depressive symptoms.

CONCLUSION

In a large sample from an LMIC, social isolation and loneliness were associated with worse cognitive performance. Surprisingly, depressive symptoms decrease the strength of these associations. Future longitudinal studies are important to assess the direction of the association between social isolation and cognitive performance.

Sex differences in cognitive function among Chinese older adults using data from the Chinese longitudinal healthy longevity survey: a cross-sectional study

Objective

To compare the sex differences in cognitive function and its influencing factors among Chinese older adults.

Method

We conducted a cross-sectional study by using data from the China Longitudinal Healthy Longevity Survey (CLHLS). According to the 32 provinces and 4 municipalities directly under the Central Government of China, 3-5 counties or districts were randomly selected in each province or city (except Tibet), and then 1-3 villages or streets were randomly selected in each county or district, from which the target population was sampled. Mini Mental State Examination (MMSE) was used to assess the cognitive function of 9,262 older adults aged 65 and above in China. Descriptive analysis was applied to demonstrate the participants' demographic characteristics, health-related behaviors, social and non-social activity, disease status, mental and sleep condition. And then, univariate and multifactor analyses were performed to validate different risk factors for cognitive function, respectively in the general population, male older adults and female older adults.

Result

The older adults with cognitive impairment accounted for 10.4% of the total population. There are significant differences in cognitive function between male and female older adults. The odds of cognitive impairment in older adult women was 1.291 times that of older adult men (OR = 1.291, 95%CI: 1.084-1.538). Among the male older adults, those who were older, highly educated, spouseless, had depressive symptoms, and lacked social activities were more likely to have cognitive impairment, whereas among the female older adults, those who were older, highly educated, and lacked social activities were more likely to have cognitive impairment.

Conclusion

Overall, there are subtle differences in potential influencing factors for cognitive function between the male older adults and female older adults. Attention should be paid to the different cognitive protection measures for the older adults with different sexes.

Increased prevalence of loneliness and associated risk factors during the COVID-19 pandemic: findings from the Canadian Longitudinal Study on Aging (CLSA)

BACKGROUND

Older adults have been disproportionately impacted by COVID-19 and related preventative measures undertaken during the pandemic. Given clear evidence of the relationship between loneliness and health outcomes, it is imperative to better understand if, and how, loneliness has changed for older adults during the COVID-19 pandemic, and whom it has impacted most.

METHOD

We used "pre-pandemic" data collected between 2015-2018 (n = 44,817) and "during pandemic" data collected between Sept 29-Dec 29, 2020 (n = 24,114) from community-living older adults participating in the Canadian Longitudinal Study on Aging. Loneliness was measured using the 3-item UCLA Loneliness Scale. Weighted generalized estimating equations estimated the prevalence of loneliness pre-pandemic and during the pandemic. Lagged logistic regression models examined individual-level factors associated with loneliness during the pandemic.

RESULTS

We found the adjusted prevalence of loneliness increased to 50.5% (95% CI: 48.0%-53.1%) during the pandemic compared to 30.75% (95% CI: 28.72%-32.85%) pre-pandemic. Loneliness increased more for women (22.3% vs. 17.0%), those in urban areas (20.8% vs. 14.6%), and less for those 75 years and older (16.1% vs. 19.8% or more in all other age groups). Loneliness during the pandemic was strongly associated with pre-pandemic loneliness (aOR 4.87; 95% CI 4.49-5.28) and individual level sociodemographic factors [age < 55 vs. 75 + (aOR 1.41; CI 1.23-1.63), women (aOR 1.34; CI 1.25-1.43), and no post-secondary education vs. post-secondary education (aOR 0.73; CI 0.61-0.86)], living conditions [living alone (aOR 1.39; CI 1.27-1.52) and urban living (aOR 1.18; CI 1.07-1.30)], health status [depression (aOR 2.08; CI 1.88-2.30) and having two, or ≥ three chronic conditions (aOR 1.16; CI 1.03-1.31 and aOR 1.34; CI 1.20-1.50)], health behaviours [regular drinker vs. non-drinker (aOR 1.15; CI 1.04-1.28)], and pandemic-related factors [essential worker (aOR 0.77; CI 0.69-0.87), and spending less time alone than usual on weekdays (aOR 1.32; CI 1.19-1.46) and weekends (aOR 1.27; CI 1.14-1.41) compared to spending the same amount of time alone].

CONCLUSIONS

As has been noted for various other outcomes, the pandemic did not impact all subgroups of the population in the same way with respect to loneliness. Our results suggest that public health measures aimed at reducing loneliness during a pandemic should incorporate multifactor interventions fostering positive health behaviours and consider targeting those at high risk for loneliness.

Is there a correlation between sensory impairments and social isolation in middle-aged and older Chinese population? Cross-sectional and longitudinal evidence from a nationally representative survey

Purpose

The aim of this study is to investigate the cross-sectional and longitudinal associations between sensory impairments (SIs) including single vision impairment (SVI), single hearing impairment (SHI), and dual sensory impairments (DSI) with social isolation in the middle-aged and older Chinese population.

Methods

Data were obtained from the China Health and Retirement Longitudinal Survey (CHARLS). In total, 11,674 Chinese older adults aged over 45 were included at baseline 2011, and 6,859 participants who accomplished all four interviews from 2011 to 2018 were adapted for longitudinal analyses. Sensory status and social isolation measurements including social disconnectedness and self-perceived loneliness were collected. Assessment of social disconnectedness included the number of types of social activities in which they participated and the frequency of such participation. Loneliness referred to the subjective perception of loneliness. Other covariates included socio-demographic characteristics, medical conditions, and lifestyle-related factors. The impacts of baseline sensory status on social disconnectedness and loneliness were assessed using univariate and multivariate generalized linear models. A generalized linear model with generalized estimation equations (GEE) was used to assess the association between time-varying sensory statuses with social disconnectedness or loneliness over 8 years after being adjusted with multi-confounding factors.

Results

Participants with SIs had significantly higher levels of social disconnectedness and self-perceived loneliness, compared to those who were free of SI. All kinds of SIs were significantly associated with loneliness according to both cross-sectional and longitudinal data. The correlations between DSI and social disconnectedness or loneliness at baseline and over 8 years were also noticed. SHI was found to be significantly associated with both frequency and types of social activities according to cross-sectional data and with the frequency of social activity participation in longitudinal analysis. SVI was only associated with the types of social activities at baseline (all p-values &lt; 0.05).

Conclusion

Sensory impairments, especially dual sensory impairments, have explicitly detrimental effects on social isolation among the older Chinese population. Over time, single hearing impairment specifically jeopardizes their frequency rather than types of social activities participation.

Perceived COVID-19 pandemic impact and protective factors predicting patient-reported depression and anxiety in individuals living with cancer

BACKGROUND

The COVID-19 pandemic presents a unique, amplified threat to those living with a cancer diagnosis, but personal factors may play a role in how this affects well-being. This cross-sectional study (1) describes the impacts of COVID-19 on cancer patients' lives, and (2) explores the extent to which specific impacts of COVID-19 and noted protective factors, hope and resilience, predict two crucial patient-reported outcomes, depression and anxiety, after controlling for relevant sociodemographic and clinical factors.

METHODS

520 cancer patients and survivors in the U.S. completed an online survey during the first year of the pandemic and answered questions about COVID-19 areas of impact, psychological well-being, hope, and resilience. Hierarchical regression analyses were used to analyze the unique impact of each group of variables on patient-reported levels of depression and anxiety during the pandemic.

RESULTS

Participants strongly endorsed COVID-19 impact across several areas of life, especially social activity, well-being, and ability to acquire basic essentials. Regression models explained a substantial amount of variance in patient-reported depression (R² = .50, p < .001) and anxiety (R² = .44, p < .001), revealing COVID-19 financial impact as a significant predictor of depression (β = 0.07), and COVID-19 family impact as a significant predictor of anxiety (β = 0.14), even after controlling for the effects of relevant sociodemographic and clinical variables. Additionally, resilience and hope were the largest predictors of both depression (β = - 0.19 and - 0.37, respectively) and anxiety (β = - 0.18 and - 0.29), suggesting that they account for unique variance in patient-reported mental health during the COVID-19 pandemic and might serve as important protective factors.

CONCLUSIONS

The current results add to existing literature documenting the significant effect of COVID-19 on those living with cancer. COVID-19 impact, including financial and family well-being, as well as positive psychological constructs, hope and resilience, play a crucial role in levels of patient-reported depression and anxiety during the pandemic. As COVID-19 continues to evolve, health care providers should routinely assess psychological well-being and needs related to COVID-19 financial and family impact in an effort to appropriately align individuals with resources and support, and consider how hope and resilience can be fostered to serve as psychological buffers during this time.

A psychosocial pathway to paranoia: The interplay between social connectedness and self-esteem

The quantity and quality of social contacts have been related to self-esteem, and both social relationships and self-esteem have been implicated in the pathways to paranoia. However, how social relationships interplay with self-esteem to trigger paranoia is not well understood. This study aims to investigate whether different measures of social connectedness (social support, loneliness, and desired friendship), as well as the frequency of social contact, impact paranoia and other positive and negative psychotic-like experiences (PLE) through the indirect effect of self-esteem. Data from a sample of 169 nonclinically ascertained participants oversampled for schizotypy scores were analyzed using two different approaches: retrospective trait-like and ecological momentary measures of social connectedness. Results showed that self-esteem mediates the pathways from poor social support and social longing, but not from loneliness, to paranoia and other cognitive PLE. In contrast, pathways from social connectedness to perceptual PLE and negative PLE were not mediated by self-esteem. Results were consistent across trait-like and momentary measures. Finally, self-esteem was not implicated in the pathways from the frequency of social contact and paranoia or other forms of PLE. These results provide a comprehensive picture of how social connectedness drives specific symptoms of psychosis through self-esteem. Findings underscore the need to explore separately the quality and quantity of social relationships and suggest that the subjective experience of meaningful social bonds is key social determinants of mental health. Therefore, addressing inadequacies of social connectedness could substantially improve symptomatic and functional outcomes of psychosis.

A Middle-Range Theory of Social Isolation in Chronic Illness

Chronic illnesses and social isolation are major public phenomena that drive health and social policy worldwide. This article describes a middle-range theory of social isolation as experienced by chronically ill individuals. Key concepts include social disconnectedness, loneliness, and chronic illness. Antecedents of social isolation include predisposing factors (e.g., ageism and immigration) and precipitating factors (e.g., stigma and grief). Outcomes of social isolation include psychosocial responses (e.g., depression and quality of life), health-related behaviors (i.e., self-care), and clinical responses (e.g., cognitive function and health service use). Possible patterns of social isolation in chronic illness are described.

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.

Validation of the Portuguese version of the social isolation scale with a sample of community-dwelling older adults

Objectives

The aim of this study was to analyze the psychometric properties (reliability and validity) of the Social Isolation Scale (SIS) in a sample of Portuguese community-dwelling older adults.

Methods

A transversal descriptive study was carried out with a convenience sample of 250 community-dwelling older adults (≥65 years). The survey comprised a sociodemographic questionnaire, SIS, Geriatric Depression Scale-4 (GDS-4), 6-item Lubben Social Network Scale (LSNS-6), a loneliness self-assessment question, and Satisfaction with Life Scale (SWLS). Construct validity (confirmatory factor analysis) and convergent validity were analyzed, and ISI internal reliability (composite reliability), external reliability (test-retest, intraclass correlation coefficient) and inter-rater reliability (Cohen's kappa coefficient) were evaluated.

Results

Confirmatory factor analysis showed a two-factor model with an excellent index of fit. The SIS showed significant correlations with LSNS-6 (r _s  = 0.47), SWLS (r _s  = 0.26), the loneliness self-assessment question (r _s = 0.35), and GDS-4 (r _s  = -0.16). SIS composite reliability was good (0.708). The inter-class correlation coefficient varied from 0.84 to 0.98. The Cohen's kappa coefficient ranged from 0.936 to 1.

Conclusions

SIS has been shown to be a valid and reliable instrument for assessing social isolation among Portuguese community-dwelling older adults. Healthcare professionals, particularly nurses working in community settings, can use SIS to assess social isolation in older adults to design, implement, and evaluate interventions.

Within-Person Dynamics of Objective and Subjective Social Isolation in Midlife and Later Life

ObjectivesTo investigate the within-person dynamics of objective and subjective social isolation among U.S. middle-aged and older adults and to explore gender differences in this relationship. Methods: Four waves of data from the Health and Retirement Study (HRS, 2006-2018, N = 5437) and the multiple group random intercept cross-lagged panel model were used. Results: Within-person deviation in expected subjective isolation predicted deviation in expected objective isolation years later. No corresponding cross-lagged effect of objective isolation on subjective isolation was found. Gender differences were detected: the within-person cross-lagged positive effect of subjective isolation on objective isolation was significant for men but not for women. Discussion: This study provides evidence for a unidirectional relationship between subjective and objective isolation at the within-person level: higher than expected increase in subjective isolation predicts higher than expected increase in subsequent objective isolation. This within-person process is more salient in men than in women.

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.

Pilot study of Qigong/Tai Chi Easy acute effects of meditative movement, breath focus and "flow" on blood pressure, mood and oxytocin in older adults

BACKGROUND

Older adults are increasingly lonely and at risk for hypertension. Endogenous oxytocin levels are associated with lowering blood pressure (BP), suggesting value in increasing oxytocin. Regular practice of Tai Chi improves BP and mood; we explored a single session of Tai Chi Easy (TCE) with older adults and feasibility of measuring oxytocin as a key biomarker.

METHOD

In a single-arm pre-post design pilot study, 21 older adults (age 55-80) with mild-moderate hypertension practiced a single session (50-min) TCE. BP, psychosocial measures, and saliva samples were collected pre/post to examine feasibility of acute measures of oxytocin and explore effect sizes of outcomes. Participants (N = 21; 19 % Latinx, 76.2 % female, mean age 66.76).

RESULTS

BP systolic: 138.43-134.86; diastolic 78.48-78.00 (p > .05; Cohen's d -0.23; -0.08 respectively). Total Mood Disturbance (TMD) and Connection (CN) improved [TMD mean pre 41.891 (SD=19.60) to post 35.00 (SD=10.21), p = .01; Cohen's d - 0.67); CN mean 7.85 (SD=2.01) to post 9.05 (SD=1.00), p = .01; Cohen's d 0.70]. Baseline oxytocin was positively correlated with baseline loneliness (N = 14, r = .599); pre/post oxytocin changes were negatively correlated with baseline loneliness (N = 14, r = -.585). BP decrease was associated with characteristics of the intervention: "flow" (coef=.=0.58N = 17) and meditative/breath focus (coef=-1.78; N = 17).

DISCUSSION/CONCLUSION

Medium to large effect sizes indicating change in mood and connection were found for this single session intervention. Knowing that Tai Chi improves BP when practiced over time, this TCE intervention shows promise for planning a fully powered, randomized controlled study of BP, mood and perceptions of connection in hypertensive older adults. Feasibility of assessing acute salivary oxytocin is less promising. Increase in oxytocin levels occurred for those less lonely, but declined for lonelier participants. With different responses based on baseline loneliness scores, no mean change in oxytocin levels was found. Seemingly unstable levels (possibly related to interaction with study staff) suggests the need for further testing in more controlled study designs. Finally, BP associations with meditative/breath focus and flow could be further explored in future study designs addressing mediation.

You gotta walk the walk to talk the talk: protocol for a feasibility study of the Happy Older Latino Adults (HOLA) health promotion intervention for older HIV-positive Latino men

BACKGROUND

Older Latinos living with the human immunodeficiency virus (HIV) have been disproportionately affected by the epidemic and experience compounded health disparities that have deepened over time. These health disparities are largely related to lifestyle and are either preventable or amenable to early detection or intervention. Despite existing resources to deliver an intervention to reduce this compounded health disparity, there is little information on the effects of health promotion interventions on indices of cardiometabolic risk in midlife and older Latinos living with HIV. The Happy Older Latinos are Active (HOLA) intervention is an innovative health promotion program that is uniquely tailored to meet the diverse needs and circumstances of older Latinos with HIV. The goal of this manuscript is to describe the protocol of a feasibility study of the HOLA health promotion intervention for older HIV-positive Latino men.

METHODS/DESIGN

HOLA, which is informed by Behavioral Activation and Social Learning theory is a community health worker (CHW)-led, multicomponent, health promotion intervention consisting of: (1) a social and physical activation session; (2) a moderately intense group walk led by a CHW for 45 min, 3×/week for 16 weeks; (3) pleasant events (e.g., going to brunch with friends) scheduling. Eighteen community dwelling Latinos living with HIV aged 50+ will be recruited for this feasibility study adapting the HOLA intervention. Participants will be assessed at three time points (baseline, post-intervention, and 3 months post-intervention) on measures of cardiometabolic risk factors (waist circumference, dyslipidemia, hypertension, and glucose), psychosocial functioning, and health-related quality of life.

CONCLUSIONS

If HOLA can be delivered successfully by CHWs, then the scalability, accessibility, and potential for dissemination is increased. Additionally, this study will inform feasibility and identify modifications needed in the design of a larger hypothesis testing study.

Changes in Community-Dwelling Elderly's Activity and Participation Affecting Depression during COVID-19 Pandemic: A Cross-Sectional Study

We determined the changes in the activity or participation of the community-dwelling elderly in Japan during the COVID-19 pandemic and identified the activities leading to depression. This will allow us to evaluate rehabilitation interventions that can be used to minimize or eliminate the negative impact of COVID-19 on today's community-dwelling elderly. Herein, demographics, activity or participation (Activity Card Sort-Japan version: ACS-JPN), the number of social networks (Lubben Social Network Scale: LSNS), and depression (Geriatric Depression Scale: GDS) were examined in 74 community-dwelling elderly in Japan from August to October 2020. A statistical analysis was conducted to determine the effect of demographics on GDS, LSNS, and ACS-JPN, to compare the activity retention rates of the four domains using ACS-JPN, and to extract the activities that might affect depression using a generalized linear model. The results show that the retention of leisure activity with a high physical demand (H-leisure) and sociocultural activities was significantly lower than instrumental activities of daily living and leisure activity with a low physical demand (L-leisure). L-leisure and the number of social networks were possible risk factors for depression during the pandemic. This study highlighted the importance of maintaining the number of L-leisure and social networks at home to prevent depression in community-dwelling elderly when they could not perform outdoor activities and direct interpersonal interaction.

The impact of loneliness and social isolation on the development of cognitive decline and Alzheimer's Disease

Alzheimer's Disease (AD) is the leading cause of dementia, observed at a higher incidence in women compared with men. Treatments aimed at improving pathology in AD remain ineffective to stop disease progression. This makes the detection of the early intervention strategies to reduce future disease risk extremely important. Isolation and loneliness have been identified among the major risk factors for AD. The increasing prevalence of both loneliness and AD emphasizes the urgent need to understand this association to inform treatment. Here we present a comprehensive review of both clinical and preclinical studies that investigated loneliness and social isolation as risk factors for AD. We discuss that understanding the mechanisms of how loneliness exacerbates cognitive impairment and AD with a focus on sex differences will shed the light for the underlying mechanisms regarding loneliness as a risk factor for AD and to develop effective prevention or treatment strategies.

Evaluating the impact of loneliness and social isolation on health literacy and health-related factors in young adults

Objectives

In current study, we aim to extend previous research by investigating the unique impact of loneliness on health literacy and health-related factors of young adults, after controlling for social isolation, depressive symptomology, and social anxiety, as well as evaluate how social isolation and loneliness differ in their impact on health literacy, and health-related factors among young adults, after accounting for abovementioned concomitant variables.

Methods

Using a cross-sectional study design, 521 young adults completed an online survey in 2020, where they self-reported their loneliness, social isolation, health-related factors, and health literacy data.

Results

Increased loneliness was associated with decrease in several health literacy domains (e.g., poorer social support for health, lower appraisal of health information, among others) and increase in some health-related factors (e.g., higher perceived stress, higher negative affect), among young adults, even after controlling for social anxiety, depressive symptomology, and social isolation. Contrastingly, increase in social isolation was associated with changes in some health-related factors - more somatic health complaints, higher alcohol use, poorer cognitive and physical functioning, and lower scores for only one health literacy domain (i.e., social support for health) among young adults, after adjusting for the influence of social anxiety, depressive symptomology, and loneliness.

Conclusion

Even after accounting for the influence of several co-occurring social and mental health symptoms, higher loneliness was associated poorer health literacy and health-related factors in young adults. We also found loneliness and social isolation may differ in the mechanisms through which they impact health literacy and health-related factors in young adults.
