  3. A Prospective Study of Social Isolation, Loneliness, and Mortality in Finland

    Jussi Tanskanen, Timo Anttila · 2016 · American Journal of Public Health · 156 citations

    Objectives. To estimate the simultaneous effects of social isolation and loneliness on mortality. Methods. We analyzed a representative Finnish sample (n = 8650) from the cross-sectional Living Conditions Survey of 1994, with a 17-year follow-up period (1995–2011), by using Cox regression models adjusted for several possible confounding variables. We examined the possible nonlinear threshold effect of social isolation on mortality. Results. The analyses revealed that social isolation predicted mortality even after we controlled for loneliness and control variables. The connection between social isolation and mortality was linear in nature and there was no synergistic effect between social is

  4. Loneliness, social isolation, cardiovascular disease and mortality: a synthesis of the literature and conceptual framework

    S. Hodgson, Isabella Watts, S. Fraser, et al. · 2020 · Journal of the Royal Society of Medicine · 152 citations

    To conduct a systematic review and develop a conceptual framework on the mechanisms linking loneliness, social isolation, health outcomes and mortality. Electronic databases were systematically searched (PubMed, MEDLINE, Scopus and EMBASE) from inception to October 2018 followed by manual searching to identify research on loneliness, social isolation and mortality in adults published in the English language. Articles were assessed for quality and synthesised into a conceptual framework using meta-ethnographical approaches. A total of 122 articles were included. These collated observational designs examining mediators and moderations of the association in addition to qualitative studies explo

  5. Economic gradients in loneliness, social isolation and social support: Evidence from the UK Biobank.

    Claryn S. J. Kung, S. Pudney, Michael A. Shields · 2022 · Social science & medicine · 71 citations

    Despite the substantial literature on how loneliness is associated with poor health and premature mortality, there is little detailed research on the extent of its economic gradients. We provide this evidence using a sample of around 400,000 respondents aged 40-70 years from the UK Biobank, who were assessed between 2006 and 2010. We focus on differences in loneliness, as well as social isolation and a lack of social support, across educational attainment, household income, local area deprivation, and recent experience of financial stress. We employ two statistical approaches, the first exploiting the large sample size and detailed geographical information about where respondents live, so we

  6. Affective Neuroscience of Loneliness: Potential Mechanisms underlying the Association between Perceived Social Isolation, Health, and Well-Being

    A. Finley, S. Schaefer · 2022 · Journal of psychiatry and brain science · 71 citations

    Loneliness, or the subjective feeling of social isolation, is an important social determinant of health. Loneliness is associated with poor physical health, including higher rates of cardiovascular disease and dementia, faster cognitive decline, and increased risk of mortality, as well as disruptions in mental health, including higher levels of depression, anxiety, and negative affect. Theoretical accounts suggest loneliness is a complex cognitive and emotional state characterized by increased levels of inflammation and affective disruptions. This review examines affective neuroscience research on social isolation in animals and loneliness in humans to better understand the relationship betw

  7. Plasma proteomic signatures of social isolation and loneliness associated with morbidity and mortality

    Chun Shen, Ruo-Han Zhang, Jin-Tai Yu, et al. · 2025 · Nature Human Behaviour · 69 citations

    The biology underlying the connection between social relationships and health is largely unknown. Here, leveraging data from 42,062 participants across 2,920 plasma proteins in the UK Biobank, we characterized the proteomic signatures of social isolation and loneliness through proteome-wide association study and protein co-expression network analysis. Proteins linked to these constructs were implicated in inflammation, antiviral responses and complement systems. More than half of these proteins were prospectively linked to cardiovascular disease, type 2 diabetes, stroke and mortality during a 14 year follow-up. Moreover, Mendelian randomization (MR) analysis suggested causal relationships fr

  8. Loneliness, Social Isolation, and All-Cause Mortality in a Large Sample of Older Adults

    Timothy L. Barnes, Manik Ahuja, S. MacLeod, et al. · 2022 · Journal of Aging and Health · 68 citations

    Objectives Using data from a large random sample of U.S. older adults (N = 7982), the effect of loneliness and social isolation on all-cause mortality was examined considering their separate and combined effects. Methods The UCLA-3 Loneliness Scale and the Social Network Index (SNI) were used to define loneliness and social isolation. Cox proportional hazards regression models were performed. Results Among study participants, there were 548 deaths. In separate, adjusted models, loneliness (severe and moderate) and social isolation (limited and moderate social network) were both associated with all-cause mortality. When modeled together, social isolation (limited and moderate social network)

  15. Comparing Loneliness, Social Inactivity, and Social Isolation: Associations with Health-Related Quality of Life and Mortality among Home-Dwelling Older Adults

    L. Rautiainen, Anu H. Jansson, M. Knuutila, et al. · 2024 · Gerontology · 7 citations

    Abstract Introduction: Loneliness, social inactivity, and social isolation are intertwined concepts. When assessed separately, they indicate poor well-being, adverse health effects, and increased mortality. Studies exploring overlapping and comparing the prognosis of these concepts are scarce. We investigated (1) overlapping of concepts of loneliness, social inactivity, and social isolation, (2) characteristics of groups: group 0 (not lonely, socially inactive, or socially isolated), group 1 (lonely), group 2 (not lonely but socially inactive and/or socially isolated), and (3) the health-related quality of life (HRQoL), psychological well-being (PWB), and 3.6-year mortality of these groups.

  17. The Link between Loneliness, Social Isolation, and Cardiovascular Disease

    Khairina, Y. Ibrahim · 2024 · Jurnal Psikiatri Surabaya · 3 citations

    Introduction: Cardiovascular disease (CVD) is a major cause of morbidity and mortality worldwide. Loneliness, a subjective feeling of social isolation, and social isolation, an objective lack of social connections, contribute to social vulnerability and physical frailty. Psychological factors and social support play important roles in CVD, affecting health behaviors and physiological mechanisms. This review aims to provide an understanding of how loneliness and social isolation impact CVD. Methods: A literature review was conducted to identify relevant studies investigating the association between loneliness, social isolation, and cardiovascular disease. Results: The findings indicate that s

    Background Adverse health conditions may serve as intermediate states linking loneliness and social isolation with excess mortality. We examined whether loneliness and social isolation are primarily associated with the risk of developing an adverse health condition or with prognosis after diagnosis. Methods A cohort of 236 879 individuals from the UK Biobank was followed from baseline in 2006–2010 until death or administrative end of follow-up in 2022. The incidence of three broad categories of adverse health conditions, (1) neoplasms, (2) endocrine, nutritional and metabolic diseases and (3) circulatory diseases, was recorded through self-report or register-based data.

  21. Associations of loneliness, social isolation and healthy lifestyle with life expectancy free of major physical disease and mental disorder

    Xuan Wang, Hao Ma, Yoriko Heianza, et al. · 2026 · Nature Communications · 1 citations

    Loneliness and social isolation are linked to higher risks of mortality and a range of adverse physical diseases and mental disorders, yet the extent to which they affect overall health and quality of life remains unclear. Here we show that loneliness and social isolation are more strongly associated with life expectancy free of mental disorder than with life expectancy free of physical disease. This study includes 277,489 adults from the UK Biobank who are initially free of seven major chronic diseases (type 2 diabetes, cardiovascular disease, chronic respiratory disease, neurodegenerative disease, cancer, depression, and anxiety). At age 50, women and men experiencing both loneliness and s

  23. SOCIAL ISOLATION, LONELINESS, AND MEN'S HEALTH

    Harry O Taylor · 2019 · Innovation in Aging · 1 citations

    Strong and fulfilling relationships are important components of men’s health and well-being across the life course; however, social isolation and loneliness are important but under-assessed conditions among older men. This is important to note because older men often subscribe to common masculinity themes regarding independence and self-sufficiency which places them at greater risk for social isolation and loneliness in comparison to older women. The purpose of this presentation is to review the social isolation and loneliness literature specifically among older men by 1) discussing gender differences, and the potential mechanisms behind these differences, in social isolation and loneliness,

  24. Loneliness, Social Isolation, and Depression among Older Adults in Nigeria: A Public Health Crisis

    Ujunwa Favour Agu, Ayomikun Nifemi Dahunsi, Leticia Appiah, et al. · 2025 · Journal of Disease and Global Health

    Nigeria is undergoing a rapid demographic transition, with a growing proportion of its population entering old age. Despite this trend, the mental health needs of older adults remain significantly under-addressed. Among the most pressing challenges are loneliness, social isolation, and depression—interrelated but distinct psychosocial conditions that contribute profoundly to morbidity, diminished quality of life, and premature mortality in later life. Loneliness refers to the subjective perception of inadequate social relationships, while social isolation is defined by a lack of actual social contact; both are potent risk factors for late-life depression, which is often underdiagnosed and un
