How digital media drive affective polarization through partisan sorting.

Politics has in recent decades entered an era of intense polarization. Explanations have implicated digital media, with the so-called echo chamber remaining a dominant causal hypothesis despite growing challenge by empirical evidence. This paper suggests that this mounting evidence provides not only reason to reject the echo chamber hypothesis but also the foundation for an alternative causal mechanism. To propose such a mechanism, the paper draws on the literatures on affective polarization, digital media, and opinion dynamics. From the affective polarization literature, we follow the move from seeing polarization as diverging issue positions to rooted in sorting: an alignment of differences which is effectively dividing the electorate into two increasingly homogeneous megaparties. To explain the rise in sorting, the paper draws on opinion dynamics and digital media research to present a model which essentially turns the echo chamber on its head: it is not isolation from opposing views that drives polarization but precisely the fact that digital media bring us to interact outside our local bubble. When individuals interact locally, the outcome is a stable plural patchwork of cross-cutting conflicts. By encouraging nonlocal interaction, digital media drive an alignment of conflicts along partisan lines, thus effacing the counterbalancing effects of local heterogeneity. The result is polarization, even if individual interaction leads to convergence. The model thus suggests that digital media polarize through partisan sorting, creating a maelstrom in which more and more identities, beliefs, and cultural preferences become drawn into an all-encompassing societal division.

Variety Is the Spice of Life: Diverse Social Networks Are Associated With Social Cohesion and Well-Being.

Both homophily and heterophily are observed in humans. Homophily reinforces homogeneous social networks, and heterophily creates new experiences and collaborations. However, at the extremes, high levels of homophily can cultivate prejudice toward out-groups, whereas high levels of heterophily can weaken in-group support. Using data from 24,726 adults (M = 46 years; selected from 10,398 English neighborhoods) and the composition of their social networks based on age, ethnicity, income, and education, we tested the hypothesis that a middle ground between homophily and heterophily could be the most beneficial for individuals. We found that network homophily, mediated by perceived social cohesion, is associated with higher levels of subjective well-being but that there are diminishing returns, because at a certain point increasing network homophily is associated with lower social cohesion and, in turn, lower subjective well-being. Our results suggest that building diverse social networks provides benefits that cannot be attained by homogeneous networks.

Social cohesion and associations with sedentary time, physical activity and dietary quality in The Maastricht Study.

INTRO: We aim to investigate the relationship between social cohesion and sedentary behavior (SB), total physical activity (PA), moderate-to-vigorous PA (MVPA), and dietary quality. Additionally, we assess whether these associations are independent of neighborhood walkability and the food environment. METHODS: A total of 7641 participants from The Maastricht Study in the Netherlands between the ages of 40 and 75 years were analyzed. Neighborhood social cohesion was obtained by participant questionnaire completed at baseline and measured by the Dutch Livability meter. Home addresses were linked to geographic information system (GIS) data from the Geoscience and Health Cohort Consortium (GECCO) to create neighborhood exposures of walkability and food environment. A thigh worn accelerometer collected data to measure sedentary time, total daily PA, and MVPA. Dietary quality was measured with a food frequency questionnaire. Multivariate linear regression analyses were adjusted for age, sex, socioeconomic position, neighborhood walkability, and food environment. RESULTS: Those living in the highest quartile area of perceived social cohesion had statistically significant lower levels of SB (Q4 B: -13.04; 95% CI = -20.23, -5.85), higher total PA (Q4 B: 4.39; 95% CI = 1.69, 7.10), and higher MVPA (Q4 B: 2.57; 95% CI = 0.83, 4.31) and better diet quality (Q4 B: 1.12; 95% CI = 0.24, 2.01) compared to the lowest quartile independent of walkability and food environment. Similar results were found using the Livability meter. CONCLUSION: We discovered neighborhood social cohesion as an important obesogenic determinant that should be considered in policymaking to encourage higher levels of PA and higher diet quality.

Individual and Collective Forms of Stigma Resistance: Pathways Between HIV and Sex Work Stigma and Viral Suppression Among Female Sex Workers in the Dominican Republic.

Intersecting forms of stigma including both HIV and sex work stigma have been known to impede HIV prevention and optimal treatment outcomes among FSW. Recent research has indicated that intersectional stigma can be resisted at the community and individual level. We assessed pathways between HIV stigma, sex work stigma, social cohesion and viral suppression among a cohort of 210 FSW living with HIV in the Dominican Republic. Through Poisson regression we explored the relationship between HIV outcomes and internalized, anticipated and enacted HIV and sex work stigma, and resisted sex work stigma. We employed structural equation modeling to explore the direct effect of various forms of stigma on HIV outcomes, and the mediating effects of multi-level stigma resistance including social cohesion at the community level and occupational dignity at the individual level. 76.2% of FSW were virally suppressed and 28.1% had stopped ART at least once in the last 6 months. ART interruption had a significant negative direct effect on viral suppression (OR = 0.26, p < 0.001, 95% CI: 0.13-0.51). Social cohesion had a significant positive direct effect on viral suppression (OR = 2.07, p = 0.046, 95% CI: 1.01-4.25). Anticipated HIV stigma had a significant negative effect on viral suppression (OR = 0.34, p = 0.055, 95% CI: 0.11-1.02). This effect was mediated by the interaction between cohesion and dignity which rendered the impact of HIV stigma on viral suppression not significant. Findings demonstrate that while HIV stigma has a negative impact on viral suppression among FSW, it can be resisted through individual and collective means. Results reinforce the importance of community-driven, multi-level interventions.

A Qualitative Exploration of the Built Environment as a Key Mechanism of Safety and Social Cohesion for Youth in High-Violence Communities.

The characteristics of a neighborhood's built environment may influence health-promoting behaviors, interactions between neighbors, and perceptions of safety. Although some research has reported on how youth in high-violence communities navigate danger, less work has investigated how these youth perceive the built environment, their desires for these spaces, and how these desires relate to their conceptions of safety and perceptions of other residents. To fill this gap, this study used focus group data from 51 youth ages 13-24 living in New Orleans, Louisiana. Four themes were developed using reflexive thematic analysis: community violence is distressing and disruptive, youth use and want to enjoy their neighborhood, systemic failure contributes to negative outcomes, and resources and cooperation create safety. This analysis indicates that young people desire to interact with the built environment despite the threat of community violence. They further identified built environment assets that facilitate socialization and recreation, such as local parks, and social assets in the form of cooperation and neighbor-led civic engagement initiatives. In addition, the youth participants demonstrated awareness of structural inequities that influence neighborhood health and violence-related outcomes. This study contributes to efforts to understand how youth with high levels of community violence exposure understand and interact with the built and social environments.

Impact of Neighborhood Social Cohesion and Rodent Sightings on Mental Health among Residents of New York City During the COVID-19 Pandemic.

Common mental disorders such as depression and anxiety are prevalent globally, and rates are especially high in New York City (NYC) since the COVID-19 pandemic. Neighborhood social and physical environments have been found to influence mental health. We investigated the impact of neighborhood social cohesion and neighborhood rodent sightings (as an indicator of neighborhood cleanliness) on nonspecific serious psychological distress (NSPD) status using 2020 NYC Community Health Survey data from 8781 NYC residents. Multivariable logistic regression was used to evaluate the relationships among social cohesion, rodent sightings, and NSPD adjusted for confounders and complex sampling and weighted to the NYC population. Effect measure modification of rodent sightings on the effect of social cohesion on NSPD was evaluated on the multiplicative scale by adding the interaction term to the multivariable model and, if significant, stratifying on the effect modifier, and on the additive scale using the relative excess risk due to interaction (RERI). Social cohesion was found to decrease the odds of NSPD, and rodent sightings were found to increase the odds of NSPD. We found significant evidence of effect measure modification on the multiplicative scale. In the stratified models, there was a protective effect of social cohesion against NSPD among those not reporting rodent sightings, but no effect among those reporting rodent sightings. Our findings suggest that both neighborhood social cohesion and rodent sightings impact the mental health of New Yorkers and that rodent infestations may diminish the benefit of neighborhood social cohesion.

Connecting to Community: A Social Identity Approach to Neighborhood Mental Health.

ACADEMIC ABSTRACT: Integrative theorizing is needed to advance our understanding of the relationship between where a person lives and their mental health. To this end, we introduce a social identity model that provides an integrated explanation of the ways in which social-psychological processes mediate and moderate the links between neighborhood and mental health. In developing this model, we first review existing models that are derived primarily from a resource-availability perspective informed by research in social epidemiology, health geography, and urban sociology. Building on these, the social identity model implicates neighborhood identification in four key pathways between residents' local environment and their mental health. We review a wealth of recent research that supports this model and which speaks to its capacity to integrate and extend insights from established models. We also explore the implications of the social identity approach for policy and intervention. PUBLIC ABSTRACT: We need to understand the connection between where people live and their mental health better than we do. This article helps us do this by presenting an integrated model of the way that social and psychological factors affect the relationship between someone's neighborhood and their mental health. This model builds on insights from social epidemiology, health geography, and urban sociology. Its distinct and novel contribution is to point to the importance of four pathways through which neighborhood identification shapes residents' mental health. A large body of recent research supports this model and highlights its potential to integrate and expand upon existing theories. We also discuss how our model can inform policies and interventions that seek to improve mental health outcomes in communities.

Impact of neighborhood context on self-rated health among very old adults living in Germany: a cross-sectional representative study.

BACKGROUND: Increasingly, evidence has shown that different aspects of neighborhood context play a significant role in self-rated health, one of the key health indicators in advanced age. Nevertheless, very old adults are often under represented or excluded from such research. Therefore, the first aim of this study was to examine whether social, socioeconomic, and physical neighborhood context is associated with self-rated health in the very old population of Germany. The second objective was to explore whether the link of socioeconomic and physical neighborhood context with self-rated health is moderated by availability of social resources in neighborhoods. METHODS: Data from the representative survey, "Old Age in Germany" (D80+) were employed. In total, the study sample of D80+ included 10,578 individuals aged 80 years and over. Additionally, the D80+ data were matched with the freely accessible regional dataset of the Federal Institute for Research on Building, Urban Affairs, and Spatial Development. Two self-rated items (place attachment and social cohesion) were used to assess social neighborhood context. Socioeconomic context of neighborhoods was operationalized by German index of socioeconomic deprivation. To evaluate physical context, perceived measures of building conditions and walkability were included. Using the maximum likelihood estimator with robust standard errors, logistic regression models were estimated to analyze the relationship between neighborhood context (social, socioeconomic, and physical context, as well as their interactions) and self-rated health. RESULTS: Including 8,066 participants in the analysis, the findings showed that better condition of residential building, higher walkability, being closely attached to outdoor places, and higher social cohesion were associated with higher chance to report good self-rated health of very old adults. In the adjusted models, the German socioeconomic deprivation index was not related to self-rated health. The effect of socioeconomic and physical neighborhood context on self-rated health did not differ according available neighborhood social resources. CONCLUSIONS: The results indicate that especially more favorable conditions in social and physical neighborhood context are associated with good self-rated health in the very old population of Germany. Further studies should consider multiple aspects of neighborhood context as well as their interplay when examining the neighborhood impact on self-rated health in older populations.

The impact of social cohesion and risk communication on excess mortality due to COVID-19 in 213 countries: a retrospective analysis.

BACKGROUND: Tools for assessing a country's capacity in the face of public health emergencies must be reviewed, as they were not predictive of the COVID-19 pandemic. Social cohesion and risk communication, which are related to trust in government and trust in others, may have influenced adherence to government measures and mortality rates due to COVID-19. OBJECTIVE: To analyse the association between indicators of social cohesion and risk communication and COVID-19 outcomes in 213 countries. RESULTS: Social cohesion and risk communication, in their dimensions (public trust in politicians, trust in others, social safety nets, and equal distribution of resources index), were associated with lower excess mortality due to COVID-19. The number of COVID-19-related disorder events and government transparency were associated with higher excess mortality due to COVID-19. The lower the percentage of unemployed people, the higher the excess mortality due to COVID-19. Most of the social cohesion and risk communication variables were associated with better vaccination indicators, except for social capital and engaged society, which had no statistically significant association. The greater the gender equality, the better the vaccination indicators, such as the number of people who received all doses. CONCLUSION: Public trust in politicians, trust in others, equal distribution of resources and government that cares about the most vulnerable, starting with the implementation of programs, such as cash transfers and combating food insecurity, were factors that reduced the excess mortality due to COVID-19. Countries, especially those with limited resources and marked by social, economic, and health inequalities, must invest in strengthening social cohesion and risk communication, which are robust strategies to better cope with future pandemics.

Solidarity and reciprocity during the COVID-19 pandemic: a longitudinal qualitative interview study from Germany.

BACKGROUND: While solidarity practices were important in mitigating the Coronavirus Disease 2019 (COVID-19) pandemic, their limits became evident as the pandemic progressed. Taking a longitudinal approach, this study analyses German residents' changing perceptions of solidarity practices during the COVID-19 pandemic and examines potential reasons for these changes. METHODS: Adults living in Germany were interviewed in April 2020 (n = 46), October 2020 (n = 43) and October 2021 (n = 40) as part of the SolPan Research Commons, a large-scale, international, qualitative, longitudinal study uniquely situated in a major global public health crisis. Interviews were analysed using qualitative content analysis. RESULTS: While solidarity practices were prominently discussed and positively evaluated in April 2020, this initial enthusiasm waned in October 2020 and October 2021. Yet, participants still perceived solidarity as important for managing the pandemic and called for institutionalized forms of solidarity in October 2020 and October 2021. Reasons for these changing perceptions of solidarity included (i) increasing personal and societal costs to act in solidarity, (ii) COVID-19 policies hindering solidarity practices, and (iii) a perceived lack of reciprocity as participants felt that solidarity practices from the state were not matching their individual efforts. CONCLUSIONS: Maintaining solidarity contributes to maximizing public health during a pandemic. Institutionalized forms of solidarity to support those most in need contribute to perceived reciprocity among individuals, which might increase their motivation to act in solidarity. Thus, rather than calling for individual solidarity during times of crisis, authorities should consider implementing sustaining solidarity-based social support systems that go beyond immediate crisis management.

Gender Differences in the Association between Psychological Distress and Sociability among Older Adult Survivors: Cross-Sectional Survey Four Years after the 2016 Kumamoto Earthquake in Japan.

Mental health deterioration after a disaster is a concern. Individuals' sociability is expected to relate to the risk of this deterioration; however, research focusing on older adults is lacking. We aimed to investigate the relationship between psychological distress and sociability in older adults who survived the 2016 Kumamoto earthquake. We conducted a self-reported questionnaire survey in 2020. Data on 3,588 people aged 65 years and over (2,024 women and 1,564 men, mean age 74.6 ± 7.2, mean ± standard deviation) were analyzed. The overall prevalence of psychological distress (the Kessler psychological distress scale: K6 ≧ 10) was 10.5%; by gender, it was 11.2% in women and 9.5% in men. Logistic regression analysis revealed that, in the total sample, age, gender, public housing, reduction in income resulting from the coronavirus disease 2019 pandemic, self-rated unhealthy conditions, subjective social isolation, and a lack of awareness of community events were positively associated with psychological distress. For women, a lack of community participation was positively related to psychological distress. For men, not knowing the change in school district after relocation was negatively associated with psychological distress, probably due to men's scarce community participation and reliance on friendships, compared to women's stronger dependence on community. Moreover, having a family member or friend to consult with was associated with a lower risk of psychological distress, regardless of gender. Gender differences were related to different conditions of social participation and types of social relationships. Enhancing community participation and family relationships among women and social contact with friends among men is essential.

Understanding the Experiences of COVID-19 Public Health Measures and Well-Being: A Qualitative Study Among Older Adults in Quebec, Canada.

This interpretative descriptive study explores how public health measures implemented during the first wave of the COVID-19 pandemic in Quebec, Canada, affected the well-being of older adults. Twenty-six participants aged 60-81 took photographs to depict how COVID-19 public health measures affected their well-being and were invited to discuss their photographs in virtual focus groups. Data were analyzed using thematic analysis. The impacts of health measures on the well-being of participants were framed according to three overarching themes. First, participants endured an intensification of ageism, feeling diminished and excluded from their social spheres. Second, they faced a burden of loneliness due to the loss of connections with their communities, particularly for those who were single and without children. Third, participants highlighted navigating a degradation of social cohesion. This manifested through tensions and distrust in both the public and private spheres, as well as acts of resistance in response to rules deemed unjust. While public health measures were essential to prevent onward transmission of COVID-19 and mortality, they negatively impacted older adults' self-image, loneliness, and trust in society. This study argues for a rethinking of public health norms specific to older adults to address potential sources of inequality. In particular, a greater emphasis is needed on social connectedness and addressing the unique needs of older adults during pandemics.

Social Participation Patterns Among Community-Dwelling Older Adults Before and During the COVID-19 Pandemic: Roles of Community Social Cohesion and Health.

The objectives of this study were to investigate groupwide variations in social participation among older adults before and during the COVID-19 pandemic and how such variations were associated with their community social cohesion and health. Data were from the National Health and Aging Trends Study (2019-2020; n = 2,597 adults aged 65 or older). Latent class analysis was used to identify groupwide variations in social participation. These variations were then incorporated into adjusted regressions to test relationships with social cohesion and health. Four participation patterns emerged: active, selective independent, occasional, and selective religious participants. Selective independent and occasional participants were likely to live in less socially cohesive communities. During the pandemic, active participants were likely to report better self-rated health and lower risks of depressive and anxiety symptoms and dementia. Findings highlight directions for policy and intervention design that can enhance social participation and support healthy aging.

Single mothers' perceptions of neighborhood social cohesion, parenting stress, adverse childhood experiences in early childhood and Black children's behavior problems in middle childhood and adolescence.

This study examined the roles of neighborhood social cohesion, adverse childhood experiences (ACEs), and parenting stress in early childhood on child behavioral outcomes in middle childhood and adolescence among socioeconomically disadvantaged Black families. To test a model linking perceptions of neighborhood social cohesion, single mothers' parenting stress, ACEs, and behavior problems in middle childhood and adolescence. We used four waves of longitudinal data from a subsample of 800 unmarried Black mothers and their children (at child birth and ages 3, 5, 9, and 15) from the Future of Families and Child Wellbeing Study, a nationally representative data set. Structural equation modeling with latent variables was used to measure direct and indirect effects. Mothers' perceptions of neighborhood social cohesion were significantly and negatively associated parenting stress (ß = -0.34, p < 0.05); parenting stress was significantly and positively related to adverse childhood experiences (ß = 0.40, p < 0.05) and behavior problems (ß = 0.32, p < 0.05); Adverse childhood experiences were significantly and positively related to behavior problems (ß = 0.26, p < 0.05); and behavior problems were indirectly influenced by neighborhood social cohesion through adverse childhood experiences (ß = -0.14, p < 0.05) and parenting stress (ß = 0.10, p < 0.05). Neighborhood factors may play a significant role in parenting stress, adverse childhood experiences in early childhood, and children's behavior problems in middle childhood and adolescence among some single mothers and children in economically and socially disadvantaged Black families. Interventions that enhance neighborhood social cohesion and foster supportive interactions among community members and organizations are recommended.

Connected communities: Perceived neighborhood social cohesion during adolescence and subsequent health and well-being in young adulthood-An outcome-wide longitudinal approach.

Does higher perceived neighborhood social cohesion in adolescence lead to better health and well-being 10-12 years later? We evaluated this question using data from a large, prospective, and nationally representative sample of US adolescents (Add Health; N = 10,963), and an outcome-wide approach. Across 38 outcomes, perceived neighborhood social cohesion was associated with some: mental health outcomes (i.e., depressive symptoms, suicidal ideation, perceived stress), psychological well-being outcomes (i.e., happiness, optimism), social outcomes (i.e., loneliness, romantic relationship quality, satisfaction with parenting), and civic/prosocial outcomes (i.e., volunteering). However, it was not associated with health behaviors nor physical health outcomes. These results were maintained after robust control for a wide range of potential confounders.

[The loneliness barometer 2024: methodology and selected results]. / Einsamkeitsbarometer 2024: Methodik und ausgewählte Ergebnisse.

Loneliness is a relatively new topic in the field of health and social policy. A pivotal requirement for the formulation of effective policies addressing loneliness in Germany lies in the access to comprehensive, longitudinal data.In 2024, the first "Loneliness Barometer" was conducted by the Loneliness Network Germany (KNE) at the Institute for Social Work and Social Pedagogy e. V. (ISS e. V.) on behalf of the Federal Ministry for Family Affairs, Senior Citizens, Women and Youth (BMFSFJ). It is a report on the long-term development of loneliness within the German population (18 years and older), for which representative data from the German Socio-Economic Panel (SOEP, 1992-2021) were analysed. The loneliness barometer is also intended to provide evidence-based statements on the long-term development of loneliness burdens in Germany in the future.This article provides an insight into the decisions made in the development of the Loneliness Barometer methodology and presents selected key findings from the first Loneliness Barometer. Leveraging data from the German Socio-Economic Panel (SOEP), the Loneliness Barometer underscores the multifaceted disparities faced by individuals grappling with heightened loneliness levels. These disparities manifest across various domains: diminished health outcomes, constrained social and financial resources encompassing education and employment, reduced economic participation, curtailed political engagement and heightened scepticism towards democratic institutions. The article concludes with considerations of the limitations and future development possibilities of the Loneliness Barometer.

Social diversity and social cohesion in Britain.

We use data from a large-scale and nationally representative survey to examine whether there is in Britain a trade-off between social diversity and social cohesion. Using six separate measures of social cohesion (generalised trust, volunteering, giving to charity, inter-ethnic friendship, and two neighbourhood cohesion scales) and four measures of social diversity (ethnic fractionalisation, religious fractionalisation, percentage Muslim, and percentage foreign-born), we show that, net of individual covariates, there is a negative association between social diversity and most measures of social cohesion. But these associations largely disappear when neighbourhood deprivation is taken into account. These results are robust to alternative definitions of neighbourhood. We also investigate the possibility that the diversity--cohesion trade-off is found in more segregated neighbourhoods. But we find very little evidence to support that claim. Overall, it is material deprivation, not diversity, that undermines social cohesion.

Associations between neighbourhood safety, social cohesion, sleep quality and sleep duration among older adults in India: Findings from the Study on Global Aging and Adult Health (WHO-SAGE), 2015.

BACKGROUND: Most studies on later-life health in India focus on families, with far less attention given to the health repercussions of neighbourhood conditions among older Indians. We address this limitation in existing research by examining the associations between perceptions of neighbourhood safety and social cohesion and sleep duration and sleep quality among older adults in India. METHODS: Data come from the Study on Global Aging and Adult Health (WHO-SAGE), India 2015 wave 2, with a sample of 7118 adults aged 50 years and above. Sleep quality and duration were assessed using subjective responses. Multivariable logistic and linear regression analyses were employed to test the research hypotheses. RESULTS: Prevalence of poor sleep quality was higher among older adults living in unsafe neighbourhoods (4.46%) than peers residing in safe neighbourhoods (3.52%), and it was also higher among those living in neighbourhoods with poor social cohesion (5.31%) than counterparts who lived in socially cohesive communities (3.10%). Older adults in neighbourhoods with poor social cohesion had higher odds of reporting compromised sleep quality (adjusted odds ratio 1.75, CI: 1.22-2.51) than those living in socially cohesive neighbourhoods. Moreover, compared to those who perceived they were living in safe neighbourhoods, their peers who perceived their neighbourhoods as unsafe reported shorter sleep duration, with a negative beta coefficient of -0.27 (CI: -0.45 to -0.085). CONCLUSION: That perceived unsafety and poor social cohesion within one's neighbourhood are associated with compromised sleep reflects the significance of making neighbourhoods safer and more integrated for later-life sleep health. In addition to micro-level strategies (e.g., balanced nutrition and physical activity), efforts to improve sleep health should optimise macro-level opportunities, such as rehabilitating and revitalising neighbourhoods, which may alleviate sleep disturbances and improve sleep outcomes among older adults.

Loneliness Among Low-Income Older Immigrants Living in Subsidized Senior Housing: Does Perceived Social Cohesion Matter?

This study compared the level of loneliness among older immigrants residing in subsidized senior housing with that of non-immigrant residents. The study also sought to examine the differential influence of perceived social cohesion on loneliness among these groups. 231 study participants were recruited from subsidized senior housing in St. Louis and the Chicago area. Multiple regression analyses showed that there was a significant difference in loneliness between immigrants and non-immigrants (b = .3, SE = 0.150, p < .05). Also, perceived social cohesion was negatively associated with loneliness (b=-.102, SE = .022, p < .001). Furthermore, immigration status moderated the relationship (b=-.147, SE = .043, p < .01), showing immigrants may benefit more from higher perceived social cohesion in terms of loneliness. The results suggest that perceived social cohesion may act as an important community-level protective factor against loneliness, particularly for older immigrants residing in subsidized senior housing. Creating socially cohesive environments, particularly for this subgroup, could be a crucial strategy for mitigating loneliness. .

Examining the Relationship Between Multilevel Resilience Resources and Cardiovascular Disease Incidence, Overall and by Psychosocial Risks, Among Participants in the Jackson Heart Study, the Multi-Ethnic Study of Atherosclerosis, and the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study.

We examined relationships between resilience resources (optimism, social support, and neighborhood social cohesion) and cardiovascular disease (CVD) incidence and assessed potential effect-measure modification by psychosocial risk factors (e.g., stress, depression) among adults without CVD in 3 cohort studies (2000-2018): the Jackson Heart Study, the Multi-Ethnic Study of Atherosclerosis, and the Mediators of Atherosclerosis in South Asians Living in America (MASALA) Study. We fitted adjusted Cox models accounting for within-neighborhood clustering while censoring at dropout or non-CVD death. We assessed for effect-measure modification by psychosocial risks. In secondary analyses, we estimated standardized risk ratios using inverse-probability-weighted Aalen-Johansen estimators to account for confounding, dropout, and competing risks (non-CVD deaths) and obtained 95% confidence intervals (CIs) using cluster bootstrapping. For high and medium (versus low) optimism (n = 6,243), adjusted hazard ratios (HRs) for incident CVD were 0.94 (95% CI: 0.78, 1.13) and 0.90 (95% CI: 0.75, 1.07), respectively. Corresponding HRs were 0.88 (95% CI: 0.74, 1.04) and 0.92 (95% CI: 0.79, 1.06) for social support (n = 7,729) and 1.10 (95% CI: 0.94, 1.29) and 0.99 (95% CI: 0.85, 1.16) for social cohesion (n = 7,557), respectively. Some psychosocial risks modified CVD HRs. Secondary analyses yielded similar findings. For optimism and social support, an inverse relationship was frequently most compatible with the data, but a positive relationship was also compatible. For neighborhood social cohesion, positive and null relationships were most compatible. Thus, specific resilience resources may be potential intervention targets, especially among certain subgroups.
