Individuals with diminished social connections are at higher risk of mental disorders, dementia, circulatory conditions and musculoskeletal conditions. However, evidence is limited by a disease-specific focus and no systematic examination of sex differences or the role of pre-existing mental disorders.
Methods
We conducted a cohort study using data on social disconnectedness (loneliness, social isolation, low social support and a composite measure) from the 2013 and 2017 Danish National Health Survey linked with register data on 11 broad categories of medical conditions through 2021. Poisson regression was applied to estimate incidence rate ratios (IRRs), incidence rate differences (IRDs), and explore sex differences and interaction with pre-existing mental disorders.
Results
Among 162,497 survey participants, 7.6%, 3.5% and 14.8% were classified as lonely, socially isolated and with low social support, respectively. Individuals who were lonely and with low social support had a higher incidence rate in all 11 categories of medical conditions (interquartile range [IQR] of IRRs, respectively 1.26–1.49 and 1.10–1.14), whereas this was the case in nine categories among individuals who were socially isolated (IQR of IRRs, 1.01–1.31). Applying the composite measure, the highest IRR was 2.63 for a mental disorder (95% confidence interval [CI], 2.38–2.91), corresponding to an IRD of 54 (95% CI, 47–61) cases per 10,000 person-years. We found sex and age differences in some relative and absolute estimates, but no substantial deviations from additive interaction with pre-existing mental disorders.
Conclusions
This study advances our knowledge of the risk of medical conditions faced by individuals who are socially disconnected. In addition to the existing evidence, we found higher incidence rates for a broad range of medical condition categories. Contrary to previous evidence, our findings suggest that loneliness is a stronger determinant for subsequent medical conditions than social isolation and low social support.

On November 30, 1625, a substantial quantity of fabric from a shipment intended for the Mansfeld Regiment’s third-most-honorable company went missing. The regimental legal establishment investigated the theft but covered up one key detail, revealed at the end of this chapter. This incident sheds light on the way this company interacted with a cloth trade that spanned Europe, in addition to the criminal activities of its captain/owner, regimental quartermaster Wolfgang Winckelmann. The investigation revealed that Winckelmann’s flag-bearer Hieronymus Sebastian Schutze also stole some fabric and distributed it to some men in this company. These men can be traced using social network analysis. This chapter argues that the concept of small group cohesion should be supplemented with the broader concept of military social networks.
Abstract: Chapter 5 presents an untold tale of an older brother and his younger sister. While their mother was the protagonist in Wolf’s classic ethnography, "A Thrice-told-Tale," the story of these children was obscured. Childhood sibling relation in “the Chinese family” was rarely studied by anthropologists, yet it is an important relation that shapes children’s moral development and family dynamics. I present systematic patterns of this sibling dyad’s social network positioning, uncover their distinct personalities, and trace their nuanced dynamics of care, rivalry and coalitional maneuvers. I closely examine projective tests data to reveal children's own emotional experience in and perspectives about their family life. This chapter is a unique narrative: in addition to illuminating childhood sibling relation, it simultaneously rediscovers the voices of these two children from ethnographic omissions and silences. Therefore, this case study echoes the dual themes of the entire book, children learning morality and anthropologists reconstructing an ethnography.
Abstract: Chapter 3 delves into the world of peer interactions. I present general patterns of children’s social networks, highlighting the importance of child-to-child ties. I illustrate the key features of this humorous, playful world and examine how peer play facilitates children’s moral learning. In peer play children are developing what I call “the spectrum of moral sensibilities:” They are learning about and engaging in cooperation and care, conflict and dominance, and creating gray areas in between. This poses a stark contrast to the imagery of “the innocent child” permeating in historical and philosophical views of Chinese childhood that fixate on the brighter side of human nature in moral cultivation. Moreover, through deciphering children’s pretend play, I argue that these non-elite children, often relegated to history’s silent margins, have a much richer inner life than my predecessors assumed. Lastly, using a human–machine hybrid approach, I find that young learners’ sensibilities in discerning layered intentions and moral sentiments defeat AI algorithms. This sheds light on the mystery of human sensemaking and inspires reflections on ethnographic epistemology.
Social isolation has been implicated in the development of cognitive impairment, but research on this association remains limited among racial-ethnic minoritized populations. Our study examined the interplay between social isolation, race–ethnicity and dementia.
Methods
We analyzed 11 years (2011–2021) of National Health and Aging Trends Study (NHATS) data, a prospective nationally representative cohort of U.S. Medicare beneficiaries aged 65 years and older. Dementia status was determined using a validated NHATS algorithm. We constructed a longitudinal score using a validated social isolation variable for our sample of 6,155 community-dwelling respondents. Cox regression determined how the interaction between social isolation and race–ethnicity was associated with incident dementia risk.
Results
Average longitudinal frequency of social isolation was higher among older Black (27.6%), Hispanic (26.6%) and Asian (21.0%) respondents than non-Hispanic White (19.1%) adults during the 11-year period (t = −7.35, p < .001). While a higher frequency of social isolation was significantly associated with an increased (approximately 47%) dementia risk after adjusting for sociodemographic covariates (adjusted hazard ratio [aHR] = 1.47, 95% CI [1.15, 1.88], p < .01), this association was not significant after adjusting for health covariates (aHR = 1.21, 95% CI [0.96, 1.54], p = .11). Race–ethnicity was not a significant moderator in the association between social isolation and dementia.
Conclusions
Older adults from racial-ethnic minoritized populations experienced a higher longitudinal frequency of social isolation. However, race–ethnicity did not moderate the positive association observed between social isolation and dementia. Future research is needed to investigate the underlying mechanisms contributing to racial-ethnic disparities in social isolation and to develop targeted interventions to mitigate the associated dementia risk.
We investigate the mental health of multicultural families (CFs) in South Korea, identify risk factors, and propose interventions to improve mental health. Adults over 19 years of age were analyzed using the Community Health Survey 2019 in South Korea, consisting of 228,952 individuals including 3,524 from multi-CFs. We employed chi-squared tests and multiple logistic regression to compare mental health between multi- and mono-CFs, exploring the influence of various factors. Multi-CFs had significantly higher levels of stress recognition (P-value = 0.010) and experiences of extreme sadness or despair (P-value = 0.002) than mono-CFs. In multi-CFs, younger group, households with lower income and people with unhealthy behaviors regarding walking or sleeping were at risk of mental health. Socially isolated families, relative to the families participating in active social gatherings, had about a 1.36 times higher risk of stress, 2 times higher experiences of extreme sadness or despair and 5.32 times higher depressive symptoms. Multi-CFs are vulnerable to mental health problems, and even within multi-CFs, groups with relatively low socioeconomic status should be prioritized since problems are more significant among them. Activated social networks can help multi-CFs integrate into society and promote mental health.
Digital media have changed the ways people mobilise and act collectively in times of crisis. During the Russian aggression against Ukraine, they have been at the forefront of war coverage giving users the possibility to share experiences of wartime reality. To critically engage in the mediatisation of the current war in the context of war witnessing, this article aims at studying the war diaries shared on media during the Russo-Ukrainian war. More precisely, this study focuses on the analysis of Facebook and MyWar platform digital war diaries that were triggered by Russia's full-fledged invasion of Ukraine 2022. The article seeks to understand the main tools for experiencing and constructing wartime reality and war trauma. The experimental work presented here provides one of the first investigations into how wartime witnessing of Russian aggression is happening and how it is shared in the contemporary space of digital media and fosters intellectual discussion about the dynamics of digital participation while witnessing and narrating war experiences.
This study examines racial discrimination faced by Black immigrants in the US, focusing on its impacts on well-being, social integration, and intergroup relations. It highlights a gap in understanding African immigrants' discrimination experiences despite documented hate crimes. The research aims to understand how Nigerian immigrants are affected by integration into US society. Using a mixed methodology with surveys and interviews, the study reveals varied correlations between integration factors and discrimination experiences. It provides nuanced insights into how integration, national identity, and social networks influence Nigerian immigrants' relationships and encounters with discrimination in the US, contributing valuable perspectives on integration-discrimination dynamics.
Empirical articles vary considerably in how they measure child and adolescent friendship networks. This meta-analysis examines four methodological moderators of children’s and adolescents’ average outdegree centrality in friendship networks: boundary specification, operational definition of friendship, unlimited vs. fixed choice design, and roster vs. free recall design. Specifically, multi-level random effects models were conducted using 261 average outdegree centrality estimates from 71 English-language peer-reviewed articles and 55 unique datasets. There were no significant differences in average outdegree centrality for child and adolescent friendship networks bounded at the classroom, grade, and school-levels. Using a name generator focused on best/close friends yielded significantly lower average outdegree centrality estimates than using a name generator focused on friends. Fixed choice designs with under 10 nominations were associated with significantly lower estimates of average outdegree centrality while fixed choice designs with 10 or more nominations were associated with significantly higher estimates of average outdegree centrality than unlimited choice designs. Free recall designs were associated with significantly lower estimates of average outdegree centrality than roster designs. Results are discussed within the context of their implications for the future measurement of child and adolescent friendship networks.
Many mediated channels are available for relational partners to use for relational partners. At times these channels are facilitating long-standing relational processes such as relational maintenance, whereas at other times the channels provide new mechanisms for relational tasks such as gathering information about potential and new romantic partners or presenting the relationship to the couple’s broader social network. This chapter reviews relational processes through the lens of social media. The chapter overviews how romantic couples use social media in the initial stages of relationships to find potential romantic partners and seek information about potential and new partners, to communicate maintenance behaviors throughout the relationship, and the impact of social media during the dissolution phases. Both positively valenced behaviors (e.g., comanaging relational impressions and using social media to create electronic tie-signs) and negatively valenced behaviors (e.g., ghosting and cyberstalking) are discussed.
Cognitive health is one of the most important determinants of the quality of life and functional independence in older adults. Recently, social relationships have emerged as a protective factor against neurocognitive disorders and cognitive decline in old age. This chapter reviews the literature investigating the influence of structural and functional aspects of social relationships on dementia risk and cognitive function in older adults. For the structural aspects, it includes studies on the effects of social networks, social contacts, and social activity participation on cognitive function in older adults. For the functional aspects, it notes the influences of social support, social conflict, and loneliness on dementia risk and cognitive aging. Lastly, the chapter discusses the potential factors that mediate or modulate the relationship between social relationships and cognitive function.
The chapter begins with Bourdieus analogy of gift giving (among the Kabyle). Focusing on relationality and the consequences of connectedness leads to principles for designing institutions. The idea is that fostering connections between individuals and groups increases mutual identification, which triggers a sense of care. Information-based strategies for environmental (and other) regulation can be guided by these principles, including that of building into the institution connections with those being affected or helped by the action. These connectivities can take advantage of new media that allow direct access to the images, voice, and face-to-face contact from the field. Many of the design principles have to do with building social networks and allowing deeper and sustained relationships across boundaries, bringing together those who normally would be disconnected. Relational principles complement those for common-pool resources and are not an alternative to them. While common-pool resource theory emphasizes the need to establish formal boundaries and rules of use, the relational theory aims to increase connectedness and foster caring.
People are not autonomous individuals but connected beings. Curae ergo sum – we care, therefore we are. Relationality – which refers to the ethic and manner by which relational considerations govern decisions and institutional arrangements can take advantage of the power of connection – uncovers how social connection, across divides, moves people to act for the other. Drawing from research on empathy, social networks, and determinants of pro-social behavior, Caring, Empathy, and the Commons builds on Ostrom's Governing the Commons. It offers a different mechanism by which collective action is induced, arguing that, sometimes, the individual thinks not in terms of individual gain but in terms of the other. Developing this concept of relationality, this book explores various strands of literature and examines how this idea might be used to foster collective action around climate, species protection, fair trade, and other dilemmas of the commons.
Social networks are critical social health factors for older adults. This study examined the association between social networks and dietary variety among community-dwelling older adults.
Design:
A cross-sectional study, using the dietary variety score (DVS) developed for older Japanese people to assess dietary variety and the Lubben Social Network Scale (LSNS-6) to assess social networks.
Setting:
N City, H Prefecture, Japan.
Participants:
Community-dwelling older adults aged ≥ 65 years (n 1229).
Results:
The LSNS-6 score in the low DVS group was lower than that in the middle and high DVS groups (12·2 ± 5·6 v. 13·4 ± 5·4 and 14·4 ± 5·7, P < 0·001). The population of social isolation (LSNS-6, < 12) in the low DVS group was higher than that in the middle and high DVS groups (43·5 % v. 35·8 % and 31·0 %, P = 0·005). Multivariate linear regression analysis showed that the LSNS-6 score was positively correlated with DVS (standardised coefficient, 0·092; P = 0·002). Social isolation was also significantly associated with a low DVS in the multivariate-adjusted logistic analysis model (OR, 1·30; 95 % CI 1·00, 1·68; P = 0·048). Stratified analysis results revealed the LSNS-6 and DVS were significantly associated in participants with the following characteristics: younger age (< 75 years), women and those living with someone.
Conclusions:
Social networks were associated with dietary variety; social isolation was related to poor dietary variety among community-dwelling older adults. An association between social networks and dietary variety was observed among young-old older adults, women and those living with someone.
Identifying the correlates of mental health resilience (MHR)—defined as the discrepancy between one’s reported current mental health and one’s predicted mental health based on their physical performance—may lead to strategies to alleviate the burden of poor mental health in aging adults. Socioeconomic factors, such as income and education, may promote MHR via modifiable factors, such as physical activity and social networks.
Design:
A cross-sectional study was conducted. Multivariable generalized additive models characterized the associations between socioeconomic and modifiable factors with MHR.
Setting:
Data were taken from the population-based Canadian Longitudinal Study on Aging (CLSA), which collected data at various data collection sites across Canada.
Participants:
Approximately 31,000 women and men between the ages of 45 and 85 years from the comprehensive cohort of the CLSA.
Measurements:
Depressive symptoms were assessed by the Center for Epidemiological Studies Depression Scale. Physical performance was measured objectively using a composite of grip strength, sit-to-stand, and balance performance. Socioeconomic and modifiable factors were measured by self-report questionnaires.
Results:
Household income, and to a lesser extent, education were associated with greater MHR. Individuals reporting more physical activity and larger social networks had greater MHR. Physical activity accounted for 6% (95% CI: 4 to 11%) and social network accounted for 16% (95% CI: 11 to 23%) of the association between household income and MHR.
Conclusions:
The burden of poor mental health in aging adults may be alleviated through targeted interventions involving physical activity and social connectedness for individuals with lower socioeconomic resources.
To overcome liabilities of foreignness and outsidership during internationalization, board interlock is an effective conduit of foreign knowledge inflows and organizational learning that firms require. We focus on the time dimension of such influence and hypothesize that the tenure of board interlocks with firms with experience in outward foreign direct investment (OFDI) in a country promotes the OFDI decision of the focal firm to that particular country. However, such an effect diminishes as the tenure of interlock ties increases. Moreover, as an alternative knowledge source, OFDI knowledge from the focal firm's neighboring region may weaken the baseline effect. Based on longitudinal data of listed firms in China, our empirical results support the hypotheses. This study enriches the literature on social network learning by identifying its temporal nature and the substitution between different knowledge sources. It also demonstrates the importance of rotating a firm's board members, so that knowledge acquisition and learning remain fresh.
Chinese domestic rural–urban migrant workers have played a substantial role in economic development since the late 1970s. This article makes an attempt to establish a two-period hiring model interpreting the impact mechanism of social networks on migrant workers’ wages. The findings indicate that the extension of social networks of both firms and workers facilitates a decrease in the information gap between them and improves extra common benefits to both.
Media and communication influence, shape, and change our societies. Therefore, this first chapter aims to explain the implications of digital communication for our societies and the relationship between media, technology, and society. The chapter introduces the concept of society from a sociological perspective and explains how societies change because of the effects technological developments have on them, and vice versa. It illustrates this interplay with the example of digital divides.
In order to explain the significance and changes of public communication in a digital society, the chapters zooms in on the media landscape and explicates the difference between new media and old (or traditional) media. It pays particular attention to the ideas of Marshall McLuhan, as his work remains a cornerstone when studying the relationship between media, technology, and society. The chapter then outlines the discipline of media linguistics and explains how media linguistics can help to make digital media and digital communication more tangible. It focuses on three key terms crucial for understanding public digital communication: multimodality, media convergence, and mediatization.
For the measles-mumps-rubella (MMR) vaccine, the World Health Organization-recommended coverage for herd protection is 95% for measles and 80% for rubella and mumps. However, a national vaccine coverage does not reflect social clustering of unvaccinated children, e.g. in schools of Orthodox Protestant or Anthroposophic identity in The Netherlands. To fully characterise this clustering, we estimated one-dose MMR vaccination coverages at all schools in the Netherlands. By combining postcode catchment areas of schools and school feeder data, each child in the Netherlands was characterised by residential postcode, primary and secondary school (referred to as school career). Postcode-level vaccination data were used to estimate vaccination coverages per school career. These were translated to coverages per school, stratified by school identity. Most schools had vaccine coverages over 99%, but major exceptions were Orthodox Protestant schools (63% in primary and 58% in secondary schools) and Anthroposophic schools (67% and 78%). School-level vaccine coverage estimates reveal strong clustering of unvaccinated children. The school feeder data reveal strongly connected Orthodox Protestant and Anthroposophic communities, but separated from one another. This suggests that even at a national one-dose MMR coverage of 97.5%, thousands of children per cohort are not protected by herd immunity.
In this chapter we discuss case studies from research on Arabic which employed various methods of social stratification. These include class-based socio-economic stratification, social network analysis, regionality, life-mode, and the community of practice construct.
