During COVID-19, international students were faced with the decision of remaining in their country of study or returning to their home countries, with little knowledge of when they would next be able to return or leave. Both choices left the students vulnerable to feelings of loneliness and social isolation. This paper examines how international students at a Scottish university experienced and navigated leaving or staying "home" and how loneliness and social isolation characterised these experiences. We further contextualise these experiences through Holbraad et al.'s (2019) prism of "rupture." The data were generated between February-July 2021 through semi-structured focus groups and qualitative questionnaire comments and were analysed through Thematic Analysis. We discuss three themes: 1) Liminal Friends and Strangers, 2) Sense of Home and Family, and 3) Staying or Leaving the Country. The study contributes to the expanding body of research on experiences of loneliness and social isolation amongst international students.

BACKGROUND: People living with HIV experience HIV stigma alongside a spectrum of aging-related health conditions that accelerate their vulnerability to the ill effects of loneliness and social isolation. Group-singing interventions are efficacious in improving psychosocial well-being among older people in the general population; however, the social curative effects of group singing have not been explored in relation to HIV stigma. By promoting group identification, bonding, and pride, group singing may reduce loneliness, social isolation, and other negative impacts of HIV stigma among older people living with HIV. Access to group-singing programs may be enhanced by technology. OBJECTIVE: While group singing has been extensively studied in older adults, group-singing interventions have not been adapted for older people living with HIV to target loneliness and social isolation in the context of HIV stigma. The objective of this study was to describe the systematic development of a group-singing intervention to reduce loneliness and social isolation among older people living with HIV. METHODS: In the San Francisco Bay Area between February 2019 and October 2019, we engaged older people living with HIV in a rigorous, 8-stage, community-engaged intervention adaptation process using the Assessment, Decision, Adaptation, Production, Topical Experts, Integration, Training, and Testing (ADAPT-ITT) framework. On the basis of a formative assessment of the needs and preferences of older people living with HIV, we selected an evidence-based group-singing intervention for older adults and systematically adapted the intervention components by administering them to a community advisory council (n=13). RESULTS: The result was United Voices, a 12-week hybrid (web-based and in-person) group-singing intervention for older people living with HIV. United Voices comprises 12 web-based (ie, via Zoom [Zoom Video Communications]) rehearsals, web-based and in-person drop-in helpdesk sessions, and a professionally produced final concert recording. CONCLUSIONS: Through an iterative process and in consultation with stakeholders and topic experts, we refined and manualized United Voices and finalized the design of a pilot randomized controlled trial to evaluate the feasibility and acceptability of the intervention protocol and procedures. The findings provide insights into the barriers and facilitators involved in culturally tailoring interventions for older people living with HIV, implementing intervention adaptations within web-based environments, and the promise of developing hybrid music-based interventions for older adults with HIV.

In group-living animals, chronic juvenile social isolation stress (SIS) can profoundly affect behavior and neuroendocrine regulation. However, its impact on social behavior in avian species, particularly regarding sex-specific neural circuit differences, remains underexplored. This study focused on zebra finches, a species known for its social clustering and cognitive abilities, to elucidate these influences. Results indicated that SIS significantly increased plasma corticosterone levels in females but not in males, suggesting a heightened stress response and susceptibility in females. Additionally, SIS disrupted sociality and flocking behavior in both sexes, with more severe impairments in social recognition observed in females. Mesotocin (MT) levels in the lateral septum of both sexes and in the ventromedial hypothalamus of females were found to mediate the SIS effect, while vasotocin (VT) levels within the social behavior network remained unchanged. Pharmacological interventions confirmed the critical role of MT in reversing SIS-induced impairments in sociality, flocking behavior, and social recognition, particularly in females. These findings highlight unique nucleus- and sex-dependent variations in MT and VT regulation, providing novel insights into the mechanisms governing avian social behavior. This study advances our understanding of the independent evolutionary pathways of neural circuits and neuroendocrine systems that modulate social behaviors across different taxonomic groups.

Background: There is clear evidence that loneliness and social isolation have profound health consequences. Documenting the associations of loneliness and social isolation with inflammatory bowel disease (IBD) symptoms, disease severity, and treatment outcomes could meaningfully improve health and quality of life in patients with IBD., Purpose: The purpose of this narrative review was to synthesize the empirical evidence on the associations of loneliness and social isolation with IBD symptoms, disease severity, and treatment outcomes., Methods: Articles were identified through systematic database searches. Quantitative studies that enrolled patients with IBD were included if they examined one of the following outcomes: (a) loneliness or social isolation or (b) IBD-related symptoms, disease severity, or treatment outcomes., Results: We identified 1,816 articles after removing duplicates. Of the 18 studies that met the inclusion criteria, 15 were cross-sectional and 3 were longitudinal. Overall, studies found that loneliness was associated with greater disease activity, functional gastrointestinal symptoms, IBD illness stigma, depressive symptoms, daily IBD symptom burden, reduced resilience, and poorer quality of life. Social isolation was associated with higher prevalence of IBD hospitalizations, premature mortality, and depression., Conclusions: Findings suggest that loneliness and social isolation are associated with poorer health and quality of life in patients with IBD. Prospective cohort studies examining the biobehavioral mechanisms accounting for the associations of loneliness and social isolation with IBD-related outcomes are needed to guide the development of psychological interventions for individuals living with IBD., (© Society of Behavioral Medicine 2024.

Background: In this study, we explored the relationship between social isolation, loneliness, and functional impairment in 50-year-old participants, by sex., Methods: Using longitudinal data from the China Health and Retirement Longitudinal Study (2018 and 2020), 6,524 participants meeting the inclusion criteria were analyzed. A cross-lag model was established to explore the associations between social isolation, loneliness, activities of daily living (ADL), and instrumental ADL (IADL) disability over time, with results stratified by sex., Results: Social isolation was not significantly associated with ADL and IADL disability, but loneliness was. Autoregressive associations indicated that social isolation, loneliness, and functional disability in 2018 predicted their exacerbations in 2020 (p < 0.001). Cross-lag analysis showed that the time-lagged effect of loneliness on ADL disability was greater in women (β = 0.27) than in men (β = 0.06); the time-lagged effect of ADL disability on loneliness was greater in men (β = 0.16) than in women (β = 0.05). The bidirectional time-lagged effects of loneliness and IADL disability showed opposite patterns between the sexes., Conclusion: Functional disability in China was significantly associated with loneliness but not with social isolation. Sex differences were observed in the time-lagged effect of loneliness on functional disability. These findings extend our understanding of the association between social relationships and functional disability in non-Western populations., Competing Interests: Declarations Ethics approval and consent to participate All participants provided informed consent, and the protocol was approved by the Ethical Review Board of Peking University (approval number: IRB00001052-11,015).

Objective: To identify the distinct clusters of social isolation among gynecologic cancer patients and analyze the predictive factors associated with each cluster., Methods: A total of 463 patients diagnosed with gynecologic cancer were recruited from three tertiary hospitals between November 2021 and March 2023. Using a two-step cluster analysis, participants were categorized into clusters based on social isolation scales. Multinomial logistic regression was then employed to predict factors influencing the identified clusters., Results: Social isolation in gynecologic cancer patients manifested in four distinct clusters: mild social isolation subgroup (13.8%), moderate social isolation subgroup (32.0%), severe isolation subgroup (33.5%), and high social isolation (20.70%). Multivariate logistic regression analysis revealed that cognitive emotional regulation, social support, negative emotions, endometrial cancer, and disease recurrence or metastasis were significant predictive factors for the identified social isolation clusters (P < 0.05)., Conclusions: The study underscored the heterogeneity in the social isolation characteristics of gynecologic cancer patients. Consequently, healthcare professionals should prioritize the identification of potential high-risk groups and devise personalized interventions to prevent and mitigate the occurrence of social isolation., (© 2024 International Federation of Gynecology and Obstetrics.)

Background: Medication adherence is essential for chronic disease management among older adults. Previous studies have shown significant links among social isolation, social support, loneliness, and medication adherence, yet most were based on cross-sectional designs., Purpose: We conducted a longitudinal cohort study among Chinese older adults with chronic diseases to explore the mediating effects of social support and loneliness in the association between social isolation and medication adherence., Methods: This study followed a cohort of 797 older adults with chronic diseases in China from 2022 to 2023. The serial mediation model was examined via bootstrapping techniques to evaluate the mediating effect of social support and loneliness in the association between social isolation and medication adherence., Results: From baseline to follow-up, there were significant decreases in social support (from 26.6 ± 6.2 to 23.5 ± 6.7) and medication adherence (from 6.7 ± 1.2 to 6.0 ± 1.5) and significant increases in social isolation (from 1.8 ± 1.3 to 2.5 ± 1.4) and loneliness (13.2 ± 4.1 to 23.5 ± 6.7), all with p < .001. A serial mediation model was confirmed, where social support and loneliness serially and partially mediated the association between social isolation and medication adherence (total effect c = -0.216, 95% CI = -0.296 to -0.136; direct effect c' = -0.094, 95% CI = -0.171 to -0.017; total indirect effect ab = -0.122, 95% CI = -0.179 to -0.070)., Conclusions: Our findings yield critical insights into the relationship between social isolation and medication adherence through various mediating mechanisms. These findings hold significant implications for devising psychosocial interventions to enhance medication adherence among older adults with chronic diseases, underscoring the pivotal role of bolstering social support and alleviating loneliness., (© Society of Behavioral Medicine 2024.

Background: Population-based studies on the relationship between social isolation and obesity, which also include younger adults, are still lacking in Germany. The aim of this study is to investigate the prevalence of social isolation in people with and without obesity. In addition, socially isolated people with and without obesity are examined with regard to socio-demographic and socio-economic factors as well as with regard to depressive symptoms., Methods: This study was based on baseline data from the LIFE Adult Study (18-79 years) from the 2011-2014 study period. The sample comprised n = 8350 participants. In addition to socio-demographic characteristics and socio-economic status (SES), data on social isolation (LSNS-6), depression (ADS), and body mass index (BMI) were collected. Evaluations were carried out using inferential statistical analyses., Results: Overall, 13.1% of the total sample were affected by social isolation. Participants with obesity (20.4%) had a significantly (p < 0.001) higher prevalence compared to those without obesity (11.4%). A better social integration was significantly associated with younger age (p < 0.001), female sex (p < 0.001), being married (and cohabiting) (p < 0.001), higher socioeconomic status (p < 0.001), and lower depressive symptoms (p < 0.001)., Discussion: A higher BMI was not associated per se with poorer social integration. However, the present study showed that socially isolated people with obesity represent a special risk group for impaired mental health and had twice the prevalence of social isolation compared to those without obesity., (© 2024.

Aim: Few studies have investigated the relationship between low dietary variety and clearly defined social isolation by gender. This study explored the association between dietary variety and social isolation, classified by operational definition, separately by gender in community-dwelling older adults., Methods: This cross-sectional study recruited respondents via mail. A total of 4798 participants aged ≥65 years participated in the on-site assessment. Social isolation was assessed by "lack of conversation," "lack of passive support," "lack of offering support," and "lack of social participation." Dietary variety was evaluated using the Dietary Variety Score (DVS)., Results: The participants' median age was 73 (interquartile range 25-75: 69-77) years, and 2147 (44.7%) were male. After adjusting for covariates, with regard to male participants, a lack of offering support (β = -0.051, P = 0.019) and a lack of social participation (β = -0.089, P < 0.001) were associated with a low DVS. For female participants, only a lack of social participation was related to a low DVS (β = -0.067, P < 0.001). A lack of conversation and passive support were not associated with a low DVS for both genders (P >0.05)., Conclusion: The results indicate that encouraging social participation, regardless of gender, as well as preventing a lack of offering support for others among men, may contribute to improving individuals' DVS.

There is a lack of questionnaires specifically designed to assess social isolation in adolescents. We developed and validated a self-report measure of social isolation in adolescents, the Social Isolation Questionnaire (QIS). A literature review on social isolation and mental health in adolescents indicated 20 questions to form QIS. Two cross-sectional surveys with 48 and 1135 adolescents, respectively, evaluated the reproducibility and validity of QIS. The Bland-Altman plot did not indicate a systematic difference between measurements 15 days apart. Bartlett's sphericity test verified a correlation between the questions and the Kaiser-Meyer-Olkin test showed good adequacy (.896) to the factor analysis. Exploratory factor analysis suggested the exclusion of three questions (loading factors <0.3), and eigenvalues (4.9-0.8) indicated that the questionnaire should be composed of three factors (dimensions). The Cronbach's alpha indicated high internal consistency of the 17 questions (0.850 overall; Dimensions: 0.815 'feeling of loneliness'; 0.760 'friendship'; and, 0.680 'Family support'). The QIS score ranged from 0 to 131 (maximum social isolation score). The correlation between QIS and depressive symptoms (r = .543) indicated the construct validity of QIS. We evaluated QIS in the Portuguese version, thus translation and cultural adaptation are necessary to evaluate the questionnaire in other settings. We constructed and validated the QIS questionnaire, a self-administered questionnaire to assess social isolation in adolescents, composed of three dimensions; feelings of loneliness, friendship and family support. The QIS questionnaire seems a very promising tool to support practitioners and researchers in assessing social isolation among adolescents., (© 2024 Society for Research on Adolescence.)

This article presents an interdisciplinary collaboration to address the needs of older adults at risk of social isolation exacerbated by the COVID-19 pandemic. An intergenerational service-learning program developed by the Pennsylvania Department of Aging was offered to several universities across the state of Pennsylvania. The authors share their experience and lessons learned from pairing older adults with graduate students studying in the fields of Gerontology, Public Health, and Social Work.

WHAT IS KNOWN ON THE SUBJECT?: People living with schizophrenia have reduced physical function and are more likely to experience loneliness than those without condition. Low physical function is associated with greater loneliness in people with psychosis. However, it is unclear whether social isolation and loneliness contribute to impaired physical function in this population. Loneliness is linked to an increased risk of physical function impairment among older individuals, but research on patients living with schizophrenia is limited. WHAT THIS PAPER ADDS TO EXISTING KNOWLEDGE?: This study is the first to evaluate the longitudinal association of social isolation and loneliness with physical function among inpatients living with schizophrenia. It showed that more than one third of the participants experienced a decline in physical function over a 2-year period. Loneliness, rather than social isolation, was associated with an increase in physical function impairment over 2 years among inpatients living with schizophrenia. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Healthcare professionals should recognize loneliness as a potential risk factor for impaired physical function among inpatients diagnosed with schizophrenia. It is recommended that people living with schizophrenia are assessed for loneliness and that interventions are offered to alleviate their feelings of loneliness. Implementing interventions to reduce loneliness may help improve physical function and overall quality of life for individuals living with schizophrenia., Abstract: INTRODUCTION: Patients living with schizophrenia often experience low physical function, which is associated with negative health outcomes. Therefore, investigating the risk factors for physical function is crucial in this population., Aim: This study examined the longitudinal association of social isolation and loneliness with physical function among inpatients living with schizophrenia., Methods: Physical function was assessed using measures of activities daily living (ADL), instrumental activities daily living (IADL) and the combination scores of ADL/IADL. Social isolation was indexed with five types of social connection and loneliness was measured using UCLA Loneliness Scale., Results: Social isolation was not associated with the measures of physical function over 2 years. Loneliness exhibited an association with IADL and ADL/IADL at follow-up, after adjustment for baseline levels of the outcomes. These associations remained when both social isolation and loneliness were simultaneously entered into the model., Discussion: Loneliness, rather than social isolation, was associated with increased physical function impairment over 2 years among inpatients living with schizophrenia., Implications for Practice: Healthcare professionals should consider loneliness as a potential risk factor for impaired physical function. It would be beneficial to assess patients for loneliness and implement interventions to reduce feelings of loneliness., (© 2024 John Wiley & Sons Ltd.)

Parents routinely encounter stress in the ecological environment that can affect offspring development (transgenerational plasticity: TGP); however, parents' interactions with conspecifics may alter how parents respond to ecological stressors. During social buffering, the presence of conspecifics can reduce the response to or increase the speed of recovery from a stressor. This may have cascading effects on offspring if conspecifics can mitigate parental responses to ecological stress in ways that blunt the transmission of stress-induced transgenerational effects. Here, we simultaneously manipulated both paternal social isolation and experience with predation risk prior to fertilisation in threespined stickleback (Gasterosteus aculeatus). We generated offspring via in-vitro fertilisation to allow us to isolate paternal effects mediated via sperm alone (i.e. in the absence of paternal care). If social buffering mitigates TGP induced by paternal exposure to predation risk, then we expect the transgenerational effects of predation exposure to be weaker when a conspecific is present compared to when the father is isolated. Offspring of predator-exposed fathers showed reduced anxiety-like behaviour and tended to be captured faster by the predator. Fathers who were socially isolated also had offspring that were captured faster by a live predator, suggesting that paternal social isolation may have maladaptive effects on how offspring respond to ecological stressors. Despite additive effects of paternal social isolation and paternal predation risk, we found no evidence of an interaction between these paternal treatments, suggesting that the presence of a conspecific did not buffer fathers and/or offspring from the effects of predation risk. Our results suggest that socially induced stress is an important, yet underappreciated, mediator of TGP and can elicit transgenerational effects even in species that do not form permanent social groups. Future studies should therefore consider how the parental social environment can affect both within and trans-generational responses to ecological stressors., (© 2024 The Author(s).

During the 2020 COVID-19 pandemic, many universities in the United States converted face-to-face classroom teaching to remote, online based learning formats. Gallaudet University was among these universities and faced particular challenges due to the need for visually accessible classrooms for d/Deaf students. Because college students are primarily made up of early and emerging adults, and d/Deaf college students have been shown to have better academic success when social connection is fostered, the current study sought to determine how d/Deaf students at Gallaudet University were emotionally impacted by the change to online learning during the COVID-19 pandemic in 2020. The research question for this study was: How did the COVID-19 pandemic and subsequent emergency switch to online course participation influence college students' experience of well-being, self-efficacy, and loneliness? Results indicated that overall, d/Deaf students at Gallaudet university had positive emotional adjustment during this transition, despite challenges. Discussion describes within-group differences by age and how the University supported students and the campus community to encourage this positive outcome.

The global COVID-19 pandemic has led educational institutions to shut down and adopt e-learning practices through computer-mediated communication. An unanticipated switch of online classes from face-to-face classes isolates students from social groups and teachers, causing online disinhibition. Therefore, this paper investigates factors influencing university students' toxic disinhibition behavior in online classrooms, WhatsApp groups, and Telegram groups. Also, social isolation has been used as a moderating variable to identify whether social isolation strengthens or weakens the proposed association. The research holds the basis of "Social Cognitive Theory" and "Theory of Planned Behavior." The data from 506 university students have been collected for analysis. The proposed framework and research hypotheses have been assessed via PLS-SEM using Smart PLS software. Findings from the study show that toxic behavior victimization, attitude, subjective norms, and behavioral control are factors that positively & significantly affect toxic disinhibition online. Furthermore, motives and self-efficacy showed an insignificant influence on toxic disinhibition. Additionally, toxic disinhibition significantly & positively affects toxic behavior. At last, social isolation is likely to have a moderation effect on the variables. Hence, the research yields guidance on reducing toxic disinhibition online. Further, implications and recommendations are discussed at the end of the study.

University student mental health and wellbeing is a concern, exacerbated by the COVID-19 pandemic. Loneliness and social isolation are drivers of student mental health problems, amenable to intervention. "Connecting People" was developed and piloted in health and social care services to support people to enhance their social connections. This paper reports results of a pre-post, single-group evaluation of training provided to 105 people supporting students in a UK university, and the feasibility of using a "Connecting People" adaptation to reduce student social isolation. Trainee confidence in supporting socially isolated students increased after training and remained high six months post-training. Positive feedback included students making new friends, and helping trainees to break down tackling loneliness and social isolation into manageable steps. Further evaluation is required to test effectiveness, but the model appears feasible to use at minimal cost, and may offer a suitable model to alleviate student social isolation.

Safety concerns continue to be challenging amid racially segregated communities of urban concentrated disadvantage. Although contributing factors to crime in such neighborhoods have been described, there is a lack of knowledge regarding how social isolation and perceptions of safety impact community health. This qualitative study explored how minoritized residents ( N  = 23) from an urban community of economic disadvantage perceived the influence of environmental and residential conditions on their health. Use of the grounded theory method produced conceptual insights into the process of how safety concerns led to fear, which created stress and prevented residents from using outdoor public spaces. Additionally, results indicated how the cyclical nature of such physical withdrawal reinforced social isolation and stigma by those outside the community, ultimately affecting residents' ability to maintain healthy living. Implications include implementing a multi-pronged public health policy that addresses safety perceptions, crime exposure, and social inclusion to improve health conditions in low-income communities.

Background: Although a preference for solitude (PS) may mitigate the negative effects of social isolation (SI) owing to the enjoyment of time alone, its impact on mental health and its underlying factors remain unclear., Methods: An Internet survey was conducted with 9000 individuals aged 20-79 years in September 2023 and the analyses were performed across three generations. SI was defined as contact with non-cohabitating family members or relatives and friends/neighbors less than once a week. The PS scale, which was used to assess whether a person preferred spending time alone, stratified respondents into three PS-level groups. Mental health status was evaluated using the K6 (distress symptoms), the WHO-5 (well-being), and the UCLA Loneliness Score (severity of loneliness) as the main outcomes. The mediation analyses assessed whether troublesomeness in socializing, a potential negative aspect of PS, could explain the association between PS and mental health status., Results: A mixed-design two-way analysis of covariance showed that both SI and PS had significant main effects on all outcomes without interactions across generations, indicating that SI and higher PS were associated with poor mental health status. The association between higher PS and poor mental status was mediated by socializing troublesomeness across generations., Limitations: The cross-sectional design prevented making causal inferences from the results. Additionally, sampling bias from Internet surveys may limit the generalizability of the results., Conclusions: The results confirmed that there is no protective effect of PS on social isolation-related poor mental health. The hassle of socializing may partly explain why people with a higher PS experience poor mental status, including greater loneliness., Competing Interests: Declaration of competing interest The authors declare no potential conflicts of interest with respect to the research., (Copyright © 2024 The Authors.

Background: The impact of social isolation on social cognition is not entirely clear., Objective: The aim of the study is to investigate the association between social isolation and social cognition., Methods: In a population-based sample of 83 individuals aged 50+ years without dementia, we assessed the relationship between social isolation (measured by the Lubben Social Network Scale - LSNS-6) and performance on emotional recognition (measured by the Emotion Recognition Task (ERT)) and on Theory of Mind (ToM) abilities (measured by the Reading the Mind in the Eyes Test (RMET)), two core aspects of social cognition., Results: No significant association was found between social isolation and ToM abilities for both the unadjusted and adjusted models. Similarly, no significant association was observed between social isolation and emotion recognition., Conclusions: Further research is needed to understand the complex correlation between social relationships and cognitive health, particularly in different cognitive domains, adopting a life course perspective., Competing Interests: Declaration of conflicting interestsThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Refugees encounter multiple psychosocial stressors post-resettlement which increases their risk of developing a mental illness. Loneliness and social isolation are commonly reported in the refugee population and have been demonstrated to be associated with multiple physical and mental health comorbidities in the general population. However, no study to date has systematically reviewed how loneliness and social isolation may affect refugees who have resettled in high-income countries. This systematic review aims to study the prevalence, risk factors, consequences, and interventions for loneliness and social isolation among refugees who have resettled in high-income countries. Systematic searches on five electronic databases yielded 2950 papers, of which 69 were deemed eligible following a double-blinded review by title and abstract then later by full text. From the included studies, it was found that the reported range of prevalence rates of loneliness (15.9-47.7%) and social isolation (9.8-61.2%) were higher than population norms. Risk factors associated with loneliness and social isolation included family separation, acculturative stress, being female or a parent and a current diagnosis of a mental illness. Loneliness and social isolation were found to be associated with depression, post-traumatic stress disorder (PTSD), psychological distress as well as physical health problems. Only three interventions addressing loneliness and social isolation were identified which demonstrates the importance of integrating social support in refugee psycho-social support programs. In summary, loneliness and social isolation were reported by a large proportion of refugees who have resettled in high-income countries. Whilst certain risk factors were pre-migratory and static, most were post-migratory in nature and were found to adversely affect mental and physical health. Thus, interventions focused on reducing loneliness and social isolation that are guided by the needs of refugee communities are urgently required., Competing Interests: Declaration of competing interest None declared., (Copyright © 2024 The Authors.

We examined the prospective associations of social isolation and loneliness with incident cardiovascular disease (CVD) among aging nonveteran and veteran women, and effect modification by veteran status. Participants with no history of myocardial infarction (MI), stroke, coronary heart disease (CHD), or coronary heart failure from the Women's Health Initiative Extension Study II self-reported social isolation, loneliness, health behaviors, health status, and veteran status. CVD and CVD subevents were physician adjudicated. Hazard ratios (HR) and 95% confidence intervals (CI) for the Interquartile Range (IQR) in social isolation (IQR = 1) and loneliness (IQR=.33) were calculated using Cox proportional hazard models adjusting for sociodemographic, health behavior, and health status characteristics. Veteran status was tested as an effect modifier. Among 52,442 women (Mean age = 79 ± 6.1; veterans n  = 1023; 89.2% non-Hispanic White), 3579 major CVD events occurred over an average 5.8 follow-up years. Compared to nonveterans, veteran women reported higher levels of social isolation ( p < .01) and loneliness ( p < .01). The CVD HR was 1.07 (95% CI, 1.04-1.10) for the IQR in social isolation and 1.03 (95% CI, 1.10-1.06) for the IQR in loneliness. The HR for the IQR in both social isolation and loneliness was 1.10 (95% CI, 1.05-1.15). Social isolation was associated with CHD (HR = 1.12; 95% CI, 1.03-1.21). The CHD HR for the IQR in social isolation was 1.12 (95% CI, 1.03-1.21). Associations did not differ by veteran status (all p -interactions > 0.08). Findings suggest that the adverse associations of social isolation and loneliness with CVD are similar among veteran and nonveteran women.

It has been 3 years since the first appearance of COVID-19 in China. During this time, social isolation was widely used as an important method to fight it. However, this measure had many negative effects on the mental health of college students. To better understand this issue, this study aims to explore the impact of social isolation and COVID-19-related stress on psychological distress among Chinese college students. Additionally, resilience has been evaluated as a key component of stress resistance in this situation. Coronavirus Stress Measure (CSM), the Connor-Davidson Resilience Scale (CD-RISC) and the Brief Symptom Inventory (BSI) were used in this study. A total of 388 Chinese college students participated in the survey via the Internet. Two groups (isolated group vs. non-isolated group) were divided according to whether they have been isolated from their classmates and families. Data analysis adopts t-test, F test and mediate effect analysis by SPSS21.0. (1) All factors, except resilience, were found to have lower scores in the isolated group; (2) significant correlations were found between all factors; (3) resilience partially mitigated the impact of COVID-19 stress on psychological symptoms. Social isolation has been found to be a significant factor contributing to negative psychological distress in Chinese college students. The COVID-19-related stress may increase the likelihood of psychological suffering among isolated group. Resilience can help reduce the negative effects of COVID-19 stress on college students. Therefore, providing appropriate psychological support tailored to different isolation situations is crucial.

Rationale & Objective: Social disconnection has been associated with poor cardiometabolic health. This study sought to investigate the associations of social isolation and loneliness with diabetic microvascular complications (DMCs) among individuals with type 2 diabetes mellitus (T2DM) and compare these associations versus those related to traditional risk factors., Study Design: Prospective cohort study., Setting & Participants: A total of 24,297 UK Biobank participants with T2DM and no DMCs at baseline., Exposure: Social isolation and loneliness were measured using self-reported questionnaires., Outcome: The incidence of DMCs defined as a composite of diabetic kidney disease, diabetic retinopathy, or diabetic neuropathy., Analytical Approach: Multivariable cause-specific hazards regression. To compare the relative importance of social disconnection with other established factors, the R 2 values of the Cox models were calculated., Results: During a median follow-up of 12.6 years, 5,530 patients were documented to experience DMCs (3,458 with diabetic kidney disease, 2,255 with diabetic retinopathy, and 1,146 with diabetic neuropathy). The highest level of social isolation was associated with an increased risk of any DMC component (most vs least: HR, 1.13; 95% CI, 1.05-1.22), especially diabetic kidney disease (HR, 1.14; 95% CI, 1.04-1.25) and neuropathy (HR, 1.31; 95% CI, 1.11-1.53). Any level of loneliness was associated with an increased risk of any DMC component (HR, 1.12; 95% CI, 1.02-1.23) and diabetic kidney disease (HR, 1.16; 95% CI, 1.03-1.30). Social isolation and loneliness exhibited associations with DMCs comparable to those of other conventional risk factors, including smoking, blood pressure, and physical activity., Limitations: Limited generalizability related to the composition of participants in the UK Biobank Study., Conclusions: Social isolation and loneliness were independently associated with a higher risk of incident DMCs among individuals with T2DM, with comparable importance to other traditional risk factors. These findings underscore social isolation and loneliness as novel and potentially modifiable risk factors for DMCs., Plain-Language Summary: Social isolation and loneliness are important social determinants that are associated with adverse cardiometabolic health. Individuals with diabetes are particularly vulnerable to social isolation and loneliness. However, the relationship of social isolation or loneliness with diabetic microvascular complications (DMCs) remains unclear. Our study used the UK Biobank study data to investigate the associations of social isolation and loneliness with the development of DMCs. We found that social isolation and loneliness were independently associated with a higher risk of incident DMCs. Remarkably, their association with DMCs was comparable to those of other lifestyle factors such as smoking, blood pressure, and physical activity. These findings collectively imply that social isolation and loneliness are 2 important potentially modifiable risk factors for DMCs among individuals with type 2 diabetes mellitus., (Copyright © 2024 The Authors.

Introduction: This study investigates the individual and combined impacts of loneliness and social isolation on 20-year mortality risks among older men and women., Methods: Utilizing data from the Norwegian Life Course, Ageing, and Generation study (NorLAG) carried out in 2002, 2007 and 2017, we assessed loneliness via direct and indirect questions, and social isolation through factors like partnership status and contact frequency with family and friends. Yearly information on mortality was derived from the national registries and was available until November 2022. Gender-stratified Cox regression models adjusted for age and other risk factors were employed., Results: Of the 11,028 unique respondents, 9,952 participants were included in the study sample, 1,008 (19.8%) women and 1,295 (26.6%) men died. In the fully adjusted models including indirectly assessed loneliness, social isolation increased the 20-year mortality risk by 16% (HR = 1.16, 95% CI 1.09-1.24) for women and 15% (HR = 1.15, 95% CI 1.09-1.21) for men. This effect was primarily driven by the absence of a partner and little contact with children for both genders. Loneliness measured with indirect questions lost its significant association with mortality after adjusting for social isolation and other factors in both genders. However, for men, reporting loneliness via a direct question was associated with a higher mortality risk, even in the fully controlled models (HR = 1.20, 96% CI 1.06-1.36). Interactions between loneliness and social isolation were not, or only borderline significantly, associated with mortality risks in the fully controlled models., Discussion: Social isolation, but not loneliness measured with indirect questions are associated with a 15-16% higher mortality risk in both men and women. However, loneliness assessed with a direct question is associated with increased mortality in men, even after controlling for social isolation and other relevant factors, which might suggest that men may deny loneliness, unless it is (very) severe. These findings emphasize the importance of methodological precision in the measurement of loneliness and social isolation., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Aartsen, Vangen, Pavlidis, Hansen and Precupetu.)

Introduction: The adverse effects of social isolation and loneliness (SI/L) have been documented among older adults in rural communities and contribute to poor health outcomes, premature disability and mortality, and increased burden on the healthcare system. The identification of factors contributing to SI/L among older adults can build the foundation for rural policymakers and leaders to allocate resources and develop tailored strategies more efficiently. The purpose of this article is to describe findings from a needs assessment designed to understand local factors that contribute to SI/L among rural older adults in a county in Northeast Tennessee. Findings from the needs assessment will be used by local stakeholders to develop strategies to promote age-friendly initiatives., Methods: Eighty-two older adults [ages 62 to 74 years (59%); non-Hispanic white (95%); female (71%)] from three senior apartment complexes in a Northeast Tennessee county completed an 87-item needs assessment survey. The evaluation of social isolation utilized Lubben's 6-item Social Network Scale, while loneliness was assessed using the 3-item UCLA Loneliness Scale. Logistic regression analysis was used to identify predictors of SI/L. Given the limited sample size, statistical significance was considered at p  < 0.10., Results: The prevalence of social isolation and loneliness was 42% and 37%, respectively. Residing in the county <5 years [Adjusted OR (AOR): 3.35; 95% CI: 1.04-10.81; p = 0.04] and reporting resource-related barriers to aging-in-place (AOR: 6.56; 95% CI: 2.00-21.57; p = 0.004) were associated with increases in the odds of social isolation; whereas interest in intergenerational activities decreased the odds of social isolation (AOR: 0.19; 95% CI: 0.05-0.69; p = 0.01). Boredom (AOR: 4.06; 95% CI: 1.63-12.11; p = 0.01) and limited knowledge about community services (AOR: 4.61; 95% CI: 1.42-15.02; p = 0.01) quadrupled the odds of loneliness. Similarly, older adults who were frail (AOR: 2.69; 95% CI: 0.88-8.17; p = 0.08) and who rated their community livability as low (AOR: 3.35; 95% CI: 0.81-13.87; p = 0.09) were more likely to experience loneliness., Discussion: This needs assessment provided important information about the individual and social drivers of SI/L among rural older adults in the community. Findings support the generation of localized data to support muti-partner efforts to design sustainable programs to address SI/L., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest. The author(s) declared that they were an editorial board member of Frontiers, at the time of submission. This had no impact on the peer review process and the final decision., (Copyright © 2024 Southerland, Zheng, Dodson, Mauck, Bacsu, Brown, Holloway, Kim, Malatyali and Smith.)

Background: Social isolation, defined as an individual's lack of social connections, is particularly prevalent among older adults. However, its association with health outcomes among the oldest-old population (aged 80 and above) was understudied., Aims: To examine the association between social isolation and the likelihood of becoming a centenarian among the oldest-old people in China, aiming to provide novel insights into promoting healthy aging and longevity., Methods: Using data from The Chinese Longitudinal Healthy Longevity Survey, conducted in 22 provinces in mainland China since 1998, we performed a community-based, prospective nested case-control study. The primary outcome was survival to the age of 100 by 2018 (the end of follow-up). Information on social isolation and other covariates was collected via a questionnaire at baseline. The degree of social isolation was categorized as low, moderate, and high. Included (n = 5,716) were 1,584 identified centenarians and 4,132 controls (deceased before reaching 100 years), matched by age, sex, and year of entry. A conditional logistic regression model was used to evaluate the association between social isolation and the likelihood of becoming a centenarian, adjusting for demographic factors, lifestyle factors, chronic disease, potential disability, optimistic attitude, and perceived loneliness., Results: Individuals with the highest social isolation score had lower odds of becoming centenarians (adjusted OR:0.82; 95% CI: 0.68, 0.98), relative to those with the least social isolation (P-value < 0.05), and this association persisted in sensitivity analyses. The association was more pronounced among ever smokers, compared to never smokers (P-value = 0.001). We did not observe significant interactions between social isolation and other covariates (P-value > 0.05 for all)., Conclusions: This study highlights the inverse association between social isolation and the likelihood of becoming a centenarian, emphasizing the need for public health initiatives to combat isolation in the older population., (© 2024.

The COVID-19 pandemic has brought unprecedented challenges to the wellbeing of the older adults worldwide. Both social isolation and loneliness are associated with decreased subjective wellbeing, but it is uncertain whether their effects are independent or if loneliness represents the affective pathway through which social isolation impairs subjective wellbeing. We therefore assessed the extent to which the association between social isolation and subjective wellbeing is mediated by loneliness. We utilized data from the 2020 China Family Panel Studies (CFPS) and focused on a sample of 3,821 individuals aged 60 and above as the participants for our study. The results revealed a significant negative association between social isolation and subjective wellbeing among the older adults during the COVID-19 pandemic. Furthermore, loneliness was found to mediate this relationship, indicating that social isolation led to increased feelings of loneliness, which in turn negatively impacted subjective wellbeing. These findings highlight the detrimental effects of social isolation and loneliness on the wellbeing of the older adults in China during the pandemic. The implications of these results emphasize the need for interventions and support systems that address social isolation and loneliness among the older adults, promoting their wellbeing and overall mental health during challenging times such as the COVID-19 pandemic., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Hao, Du and Yue.)

Background: Social isolation and loneliness are associated with increased risk of adverse health outcomes at older ages. This study evaluated whether isolation and loneliness are related to inadequate intake of micronutrients in the diet., Methods: We tested associations between social isolation and loneliness and dietary micronutrient intake 2 years later in 3713 men and women (mean age 68.26, standard deviation 7.81 years) who completed two online 24-h dietary recalls. Associations of isolation and loneliness with intake of nine minerals and vitamins that fell below national recommendations were tested using logistic regressions, adjusting for age, gender, ethnicity, education, marital status, smoking and physical activity and total energy intake., Results: The prevalence of low dietary intake varied markedly across micronutrients. Social isolation (1-point increase in a score ranging 0-5) was associated with increased odds (adjusted for covariates) of low intake of magnesium [odds ratio (OR) 1.153, 95% confidence interval (CI) 1.037-1.282, P = .009], potassium (OR 1.201, 95% CI 1.087-1.327, P < .001), vitamin B6 (OR 1.263, 95% CI 1.110-1.438, P < .001), folate (OR 1.211, 95% CI 1.093-1.341, P < .001) and vitamin C (OR 1.238, 95% CI 1.098-1.394, P < .001). These associations remained unchanged when food insecurity and impaired activities of daily living were taken into account. By contrast, loneliness was not related to the inadequate intake of any micronutrient., Conclusions: Low intake of micronutrients increases risk of age-related health problems. Attention to the dietary quality of older people with limited social contacts and little involvement in community activities might enhance health outcomes., (© The Author(s) 2024.

Objective: Few studies investigated the influence of oral parafunctional habits during the COVID-19 pandemic. Since some studies have demonstrated that signs and symptoms of temporomandibular disorder (TMD), as well as psychological alterations, increased during the COVID-19 pandemic lockdown, the aim of this study was to investigate whether social isolation is a situation that increases the prevalence of oral parafunctional habits., Methods: This was an observational case-control study. An online survey with questions about TMD symptoms (Diagnostic Criteria Symptom Questionnaire) and oral parafunctional habits (Oral Behaviours Checklist [OBC]) was administered to Brazilian residents at two different times (2020 and 2021). The participants were divided according to social isolation practices into study groups (GI: 2020, n = 507; GIII: 2021, n = 282) and control groups (GII: 2020, n = 98; GIV: 2021, n = 202)., Result: In each group, we evaluated the association of the frequency of oral parafunctional habits with the symptoms of TMD, and we observed that individuals with a greater presence of painful TMD present a greater number of oral parafunctional habits. Despite the literature showing that individuals who practiced social isolation developed more oral parafunctional habits, when analysing the association of the OBC questions in Groups GI × GII and GIII × GIV, only 'sustained talking' (p = .0022) and 'hold telephone between your hand and shoulders' (p = .0124) showed a significant difference in GI × GII. Kendall's coefficient of concordance revealed that there was a very strong concordance (GI × GII 0.9515 (p = .0087) and GIII × GIV 0.9655 (p = .0074)) between the ranks of the analysed oral parafunctional habits in all groups., Conclusion: We can state that Individuals who practiced social isolation did not present more oral parafunctional habits than individuals who did not., (© 2024 John Wiley & Sons Ltd.)

Objectives: We assessed the relationship between social isolation and functional disability in older people., Design: Comparison of longitudinal cohort studies., Setting and Participants: Harmonised longitudinal datasets from the United States, England, European countries, Japan, Korea, China and Hong Kong., Methods: Social isolation was operationalised as a composite score with five domains, such as marital status, living alone, and social contact with others. Functional disability was defined as whether the cohort participant had any difficulty in activities of daily living (ADL). In each dataset, we used robust Poisson regression models to obtain the relative risks (RRs) and the corresponding 95 % confidence intervals (CI). We combined the RRs to synthesize a pooled estimate using meta-analysis with random-effects models., Results: Overall, the social isolation composite score was not associated with ADL disability (pooled RR = 1.05, 95 % CI [0.97-1.14], n = 40,119). Subgroup analysis suggested social isolation composite score was associated with ADL disability in Asian regions (pooled RR = 1.09, 95 % CI [1.02, 1.16], but not in Western regions (pooled RR = 1.01, 95 % CI [0.96, 1.07]). The relationships between different domains of social isolation and ADL disability were heterogeneous, except that no participation in any social clubs or religious groups was consistently associated with ADL disability (pooled RR = 1.12, 95 % CI [1.04, 1.21])., Conclusion: Targeting social isolation may prevent decline in functional abilities in older adults, providing an avenue to active and healthy ageing. Nonetheless, interventions tackling social isolation should tailor to the unique cultural and social underpinnings. A limitation of the study is that reverse causality could not be ruled out definitively., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Memory plays a crucial role in cognitive health. Social isolation (SI) and loneliness (LON) are recognized risk factors for global cognition, although their combined effects on memory have been understudied in the literature. This study used three waves of data over six years from the Canadian Longitudinal Study on Aging to examine whether SI and LON are individually and jointly associated with memory in community-dwelling middle-aged and older adults (n = 14,208). LON was assessed with the question: "In the last week, how often did you feel lonely?". SI was measured using an index based on marital/cohabiting status, retirement status, social activity participation, and social network contacts. Memory was evaluated with combined z-scores from two administrations of the Rey Auditory Verbal Learning Test (immediate-recall, delayed-recall). We conducted our analyses using all available data across the three timepoints and retained participants with missing covariate data. Linear mixed models were used to regress combined memory scores onto SI and LON, adjusting for sociodemographic, health, functional ability, and lifestyle variables. Experiencing both SI and LON had the greatest inverse effect on memory (least-squares mean: -0.80 [95 % confidence-interval: -1.22, -0.39]), followed by LON alone (-0.73 [-1.13, -0.34]), then SI alone (-0.69 [-1.09, -0.29]), and lastly by being neither lonely nor isolated (-0.65 [-1.05, -0.25]). Sensitivity analyses confirmed this hierarchy of effects. Policies developed to enhance memory in middle-aged and older adults might achieve greater benefits when targeting the alleviation of both SI and LON rather than one or the other individually., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Author(s).

Background: Homebound older adults (HOAs) are particularly vulnerable to social isolation and loneliness, which engender a poorer physical and mental health, and greater cognitive decline. The purpose of this review is to map the literature to identify potential technological strategies that reduce social isolation in HOAs, and to understand facilitators and barriers for adoption and implementation., Methods: Six databases including PubMed (MEDLINE), Google Scholar, Cochrane Database, EBSCOHost, National Library ProQuest, Web of Science, and the Journal of Medical Internet Research were searched for relevant articles. Peer-reviewed literature published in English from Jan 2014 to Feb 2024 that employed technological strategies applicable to HOAs and assessed social isolation or connectedness as an outcome measure were included., Results: 107 studies were reviewed and classified into different technological categories based on their functions and features. A social technology framework encompassing delivery, hardware, software, content, training, and support was conceptualized with core characteristics identified from the reviewed technological strategies. Cost and complexity of technology, and resource commitment were identified as barriers while user-friendliness, content curation and a supportive ecosystem may facilitate the adoption of a technological strategy to address social isolation in HOAs., Conclusion: There is a need for early and concerted effort to identify HOAs, provide technology training, and empower them to tap on the digital world to complement and/or supplement social interactions. Development of cost-effective and rapid-to-implement technology is vital for HOAs who are at highest risk to social isolation., Competing Interests: Declaration of competing interest The authors declare that they have no competing interests., (Copyright © 2024 The Author(s).

Background: The high prevalence of sensory impairment and functional limitations in older adults is a significant concern, yet there is limited understanding of the relationship between these two conditions. Therefore, the objective of this study was to investigate the pathways connecting sensory impairment and functional limitations by examining serial multiple mediating effects of social isolation and cognition in older adults., Methods: Using the China Health and Retirement Longitudinal Study dataset, a sample of 4871 older adults was selected. The study variables included sensory impairment, functional limitations, social isolation and cognition, and other covariates. A hierarchical multiple linear regression model was used to assess the association between sensory impairment and functional limitations. Mediation analysis was conducted to explore the sequential multiple mediating effects of social isolation and cognitive function in the relationship between sensory impairment and functional limitations., Results: Our findings revealed a significant and positive association between sensory impairment and functional limitations (B = 0.615, 95% CI: 0.397, 0.834). After adjusting for social isolation and cognitive function, the impact of sensory impairment on functional limitations accounted for 87.19% of the total effect. Additionally, approximately 12.81% of the significant relationship between dual sensory impairment and functional limitations was mediated by social isolation and cognitive function. A serial multiple mediating pathway (sensory impairment → social isolation → cognition → functional limitations) was identified, with a coefficient of 0.013 (95% CI: 0.006, 0.020)., Conclusions: Our study provides evidence for the mediating effects of social isolation and cognition in the relationship between sensory impairment and functional limitations. Given the prevalence of functional limitations among older adults with sensory impairment, it is crucial to consider social isolation and cognitive function in efforts to reduce the burden of disability care. Future validation of these findings through longitudinal studies is necessary., (© 2024. The Author(s).)

Background: Social isolation and feelings of loneliness are very prevalent in people with neurodegenerative diseases and are associated with a lower quality of life and other negative outcomes. These problems were increased during the COVID-19 pandemic resulting in initiatives to address social isolation. Given the potential benefits of nature-based and animal-assisted intervention strategies (NATAIS), it is crucial to further investigate if and how these strategies might minimize negative effects of social isolation and feelings of loneliness in this population. Therefore, the aim of this project was to develop a research agenda for NATAIS in people with neurodegenerative diseases, especially during challenging times, such as pandemics., Methods: This article outlines the process and results of a group concept mapping procedure aimed at developing a research agenda based on a logic model. In total, 19 work group members participated through a combination of in-person and online group meetings. Additionally, face-to-face group sessions were held at two international scientific conferences, during which feedback was solicited from 12 experts in the field of NATAIS and psychogeriatrics., Results: The group concept mapping procedure resulted in 14 clusters describing various future research topics, which were further refined and detailed during group discussions. The remaining eleven clusters, encompassing important research themes within the field of NATAIS, were organized into a logic model and summarized into the research agenda. The overarching cluster 'ethical issues, possible risk factors, and their solutions' was considered the most relevant during times of increased social isolation, such as during a pandemic, along with the necessity for more accessible NATAIS., Conclusions: This project resulted in a research agenda, directing future research and fostering collaboration between practitioners and researchers in the field of NATAIS. Such an enhanced partnership between science and practice has the potential to significantly contribute to the well-being of people with neurodegenerative diseases, in their daily lives and also during pandemics., (© 2024.

Background: Older adults are vulnerable to social isolation due to declining physical and cognitive function, decreased interpersonal interactions, and reduced outdoor activities after retirement. This study aimed to develop and validate a predictive model to assess the risk of social isolation among older adults in China., Methods: Using data from the 2011 China Health and Retirement Longitudinal Study (CHARLS). The study cohort was randomly divided into training and validation groups in a 70:30 ratio. We used least absolute shrinkage and selection operator (LASSO) regression analysis with tenfold cross-validation to identify optimal predictive factors and examined the correlates of social isolation using logistic regression. A nomogram was constructed for the predictive model, and its accuracy was assessed using calibration curves. The predictive performance of the model was assessed using area under the receiver operating characteristic (ROC) curve and decision curve analysis (DCA)., Results: From the 2011 CHARLS database, 4,747 older adults were included in the final analysis, of whom 1,654 (34.8%) experienced social isolation. Multifactorial logistic regression identified educational level, marital status, gender, physical activity, physical self -maintenance ability, and number of children as predictive factors for social isolation. The predictive model achieved an AUC of 0.739 (95%CI = 0.722-0.756) in the training set and 0.708 (95%CI = 0.681-0.735) in the validation set. The Hosmer-Lemeshow test yielded P values of 0.111 and 0.324, respectively (both P > 0.05), indicating significant agreement between the nomogram and observed outcomes. The nomogram showed excellent predictive ability according to ROC and DCA., Conclusions: The predictive model developed to assess the risk of social isolation in the Chinese older adults shows promising utility for early screening and intervention by clinical healthcare professionals., (© 2024.

The association of health-related productivity loss (HRPL) with social isolation and depressive symptoms is not well studied. We aimed to examine the association of social isolation and depressive symptoms with productivity loss. Data on employed adults aged 21 years and above were derived from the Population Health Index (PHI) study conducted by the National Healthcare Group (NHG) on community-dwelling adults, residing in the Central and Northern residential areas of Singapore. The severity of depressive symptoms and social isolation were assessed using the 9-item Patient Health Questionnaire (PHQ-9) and Lubben Social Network Scale-6 (LSNS-6) respectively. Productivity loss was assessed using the Work Productivity and Activity Impairment Questionnaire (WPAI). We used Generalised Linear Models, with family gamma, log link for the analysis. Models were adjusted for socio-demographic variables (including age, gender, ethnicity, employment status, housing type) and self-reported chronic conditions (including the presence of diabetes, hypertension, and dyslipidemia). There were 2,605 working (2,143 full-time) adults in this study. The median reported percentage of unadjusted productivity loss was 0.0%, 10.0% and 20.0% for participants with social isolation, depressive symptoms, and both, respectively. In the regression analysis, mean productivity loss scores were 2.81 times (95% Confidence Interval: 2.12, 3.72) higher in participants with depressive symptoms than those without. On the other hand, social isolation was not found to be associated with productivity loss scores (1.17, 95% Confidence Interval: 0.96, 1.42). The interaction term of depressive symptoms with social isolation was statistically significant, with an effect size of 1.89 (95% Confidence Interval: 1.04, 3.44). It appeared that productivity loss was amplified when social isolation and depressive symptoms were concomitant. Our results suggested significant associations of social isolation and depressive symptoms with productivity loss. These findings highlighted the potential impact of social isolation and depressive symptoms on work performance and drew attention to the importance of having a holistic work support system that promotes social connectedness, mental wellbeing and work productivity., (© 2024.

Background: Neighborhood factors of social isolation have been understudied, hindering efforts to reduce social isolation at the neighborhood level. This study aims to investigate the longitudinal effects of neighborhood social cohesion and physical disorder on social isolation in community-dwelling older adults, as well as to examine whether race/ethnicity moderates the neighborhood-isolation relationship., Methods: We used 11-year data from the National Health and Aging Trend Study, a longitudinal national study of Medicare beneficiaries aged 65 and older. Social isolation was measured through a summary score across four domains: marital/partner status, family and friend contact, religious attendance, and club participation. A series of weighted mixed-effects logistic regression models were performed to test the study aims. Sample sizes ranged from 7,303 to 7,291 across individual domains of social isolation., Results: Approximately 20% of participants reported social isolation. Findings indicated a negative association between neighborhood social cohesion and social isolation. Higher levels of neighborhood social cohesion were longitudinally associated with lower odds of social isolation (odds ratio [OR] = 0.52, 95% CI: 0.47-0.58). Yet, the presence of neighborhood physical disorder was associated with an increased risk of overall social isolation ([OR] = 1.2, 95% CI: 1.00, 1.44). Race/ethnicity significantly moderated the effects of neighborhood social cohesion and physical disorder on social isolation. The odds of no in-person visits associated with neighborhood social cohesion are smaller among Black adults compared to White adults. Black adults had constantly lower odds of isolation from religious attendance compared to White adults regardless of the level of neighborhood social cohesion. Hispanic adults had decreased odds of having no friends associated with signs of physical disorder, while no associations were found among older White adults. White adults had higher odds of isolation from in-person visits when living in neighborhoods with signs of physical disorder, whereas no association was observed among older Black and Hispanic adults., Conclusions: This study elucidates the role of neighborhood characteristics in shaping social isolation dynamics among older adults. Furthermore, the observed moderation effects of race/ethnicity suggest the need for culturally sensitive interventions tailored to address social isolation within specific neighborhood and racial contexts., (© 2024.

Social isolation and loneliness (SIL) are public health challenges that disproportionally affect individuals who experience structural and socio-economic exclusion. The social and health outcomes of SIL for people with experiences of being unhoused have largely remained unexplored. Yet, there is limited synthesis of literature focused on SIL to appropriately inform policy and targeted social interventions for people with homelessness experience. The aim of this scoping review is to synthesize evidence on SIL among people with lived experience of homelessness and explore how it negatively impacts their wellbeing. We carried out a comprehensive literature search from Medline, Embase, Cochrane Library, PsycINFO, CINAHL, Sociological Abstracts, and Web of Science's Social Sciences Citation Index and Science Citation Index for peer-reviewed studies published between January 1st, 2000 to January 3rd, 2023. Studies went through title, abstract and full-text screening conducted independently by at least two reviewers. Included studies were then analyzed and synthesized to identify the conceptualizations of SIL, measurement tools and approaches, prevalence characterization, and relationship with social and health outcomes. The literature search yielded 5,294 papers after removing duplicate records. Following screening, we retained 27 qualitative studies, 23 quantitative studies and two mixed method studies. SIL was not the primary objective of most of the included articles. The prevalence of SIL among people with homelessness experience varied from 25 to 90% across studies. A range of measurement tools were used to measure SIL making it difficult to compare results across studies. Though the studies reported associations between SIL, health, wellbeing, and substance use, we found substantial gaps in the literature. Most of the quantitative studies were cross-sectional, and only one study used health administrative data to ascertain health outcomes. More studies are needed to better understand SIL among this population and to build evidence for actionable strategies and policies to address its social and health impacts., (© 2024.

Background: Social isolation and loneliness can co-occur; however, they are distinct concepts. There is discrepancy as some people feel lonely in social isolation, while others do not. This study sought to enhance our understanding of this discrepancy between social isolation and loneliness by investigating its related factors, with a specific focus on mental status and personality traits., Methods: This study adopted a cross-sectional study design and utilized data from the 2016 and 2018 waves of the University of Michigan Health and Retirement Study. The participants were community dwellers aged 50 years and older. The outcome measurement was defined as the discrepancy between social isolation, based on six criteria, and loneliness, assessed using the three-item version of the Revised UCLA Loneliness Scale. Multinomial logistic regression models were conducted to examine the factors associated with the discrepancy., Results: Participants with fewer depressive symptoms and higher extraversion were associated with the only social isolation group and the only loneliness group rather than the group consisting of those who felt lonely with social isolation. In addition, lower neuroticism was associated with the only social isolation group. Participants with fewer depressive symptoms, lower neuroticism, and higher extraversion were more likely not to feel lonely even with social isolation, compared to feeling lonely even in the absence of isolation., Conclusions: Mental status and personality traits may be closely related to the discrepancy between social isolation and loneliness. This study suggests that incorporating social, mental, and psychological factors may be essential for interventions in social isolation and loneliness., (© 2024. The Author(s).)

Introduction: Loneliness and social isolation are public health concerns. This study aimed to examine levels and trends in loneliness and social isolation among older adults (77+ years) in Sweden, assess subgroup variations, and determine associations between loneliness and social isolation., Methods: The 1992, 2002, 2004, 2011, 2014 and 2021 waves of the Swedish Panel Study of Living Conditions of the Oldest Old (SWEOLD) were analysed through ordered logistic and linear regressions., Results: On average, 12.5 percent of the participants experienced loneliness often/nearly always, while 6 percent were categorised as severely isolated. Loneliness and social isolation were more common in women, those aged 85+, and persons with basic education, in psychological distress or with mobility limitations. Loneliness was also associated with living alone. No increases in loneliness or isolation were identified; instead, loneliness tended to decrease in groups already experiencing lower levels of loneliness. Loneliness and social isolation were moderately associated each survey year., Discussion: This study challenges perceptions of high and increasing levels of loneliness and social isolation. Given the impact on health and wellbeing and the ageing of populations, policy and practice should still address these issues and target vulnerable groups. Subgroup analyses in trends are scarce and should be explored further in future research., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Dahlberg, von Saenger, Naseer, Lennartsson and Agahi.)

Background: Internet gaming disorder among university students has become a great concern for university counsellors worldwide since the COVID-19 pandemic. The factors influencing the development of internet gaming disorder in students during the COVID-19 pandemic could be different from those before the pandemic., Objective: This study aims to explore the associations among social isolation, self-control, and internet gaming disorder in Chinese university students and to examine whether self-control mediates the positive effects of social isolation on internet gaming disorder., Methods: A cross-sectional survey was employed to collect data from university students in Shandong province of China from April to September 2022. The Isolation subscale of the Self-Compassion Scale, Self-Control Scale, and Internet Gaming Disorder Scale were used to assess the social isolation, self-control, and internet gaming disorder among university students, respectively. Models 4 and 5 of PROCESS software were used to analyze the mediating role of self-control and the moderating role of gender on the association between social isolation and internet gaming disorder., Results: A total of 479 students were recruited from 6 universities located in 3 different regions of Shandong, China. Students had low levels of internet gaming disorder and moderate levels of social isolation and self-control, with mean scores of 8.94 (SD 9.06), 12.04 (SD 3.53), and 57.15 (SD 8.44), respectively. Social isolation was positively correlated with internet gaming disorder (r=0.217; P<.001), and self-control was negatively correlated with social isolation (r=-0.355; P<.001) and internet gaming disorder (r=-0.260; P<.001). Self-control played a mediating role in the association between social isolation and internet gaming disorder (β=-.185, 95% CI -.295 to -.087). The effects of social isolation on internet gaming disorder among female students were lower than those among male students., Conclusions: Self-control was a mediator in the association between social isolation and internet gaming disorder. Moreover, gender played a moderating role in the association between social isolation and internet gaming disorder. This study highlights the need to alleviate the development of internet gaming disorder among students during a pandemic, especially that of male students. Effective interventions that lessen social isolation and promote self-control should be developed., (©Yufang Guo, Fangyan Yue, Xiangyu Lu, Fengye Sun, Meixing Pan, Yannan Jia.

Background: Worsening loneliness and social isolation during the COVID-19 pandemic have become serious public health concerns worldwide. Despite previous research reporting persistent loneliness and social isolation under repeated emergency declarations and prolonged pandemics, long-term studies are needed to identify the actual conditions of loneliness and social isolation, and the factors that explain them., Objective: In this study, 3 web-based surveys were conducted at 1-year intervals during the 2 years after the first state of emergency to examine changes in loneliness and social isolation and the psychosocial factors associated with them in the Japanese population., Methods: The first survey (phase 1, May 11-12, 2020) was conducted at the end of the first emergency declaration period, the second survey (phase 2, June 14-20, 2021) was conducted at the end of the third emergency declaration period, and the third survey (phase 3, May 13-30, 2022) was conducted when the state of emergency had not been declared but many COVID-19-positive cases occurred during this period. We collected data on 3892 inhabitants (n=1813, 46.58% women; age: mean 50.3, SD 13.4 y) living in the 4 prefectures where emergency declaration measures were applied in phases 1 and 2. A linear mixed model analysis was performed to examine the association between psychosocial variables as explanatory variables and loneliness scores as the dependent variable in each phase., Results: While many psychosocial and physical variables showed improvement for the 2 years, loneliness, social isolation, and the relationship with familiar people deteriorated, and the opportunities for exercise, favorite activities, and web-based interaction with familiar people decreased. Approximately half of those experiencing social isolation in phase 1 remained isolated throughout the 2-year period, and a greater number of people developed social isolation than those who were able to resolve it. The results of the linear mixed model analysis showed that most psychosocial and physical variables were related to loneliness regardless of the phase. Regarding the variables that showed a significant interaction with the phase, increased altruistic preventive behavior and a negative outlook for the future were more strongly associated with severe loneliness in phase 3 (P=.01 to <.001), while the association between fewer social networks and stronger loneliness tended to be more pronounced in phase 2. Although the interaction was not significant, the association between reduced face-to-face interaction, poorer relationships with familiar people, and increased loneliness tended to be stronger in phase 3., Conclusions: This study found that loneliness and social isolation remained unresolved throughout the long-term COVID-19 pandemic. Additionally, in the final survey phase, these issues were influenced by a broader and more complex set of factors compared to earlier phases., (©Nagisa Sugaya, Tetsuya Yamamoto, Naho Suzuki, Chigusa Uchiumi.
