The associations of social health, self-injurious thoughts and behaviors with or without childhood trauma: A UK biobank study. J Affect Disord 2024; 359:145-157. [PMID: 38772505 DOI: 10.1016/j.jad.2024.05.077] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2024] [Revised: 05/11/2024] [Accepted: 05/17/2024] [Indexed: 05/23/2024]
Abstract
BACKGROUND Childhood trauma was known to increase risks of social isolation, loneliness and self-injurious thoughts and behaviors in adulthood. The aim of this study was to examine the protect and risk factors of social health, self-injurious thoughts and behaviors between adults with or without childhood trauma. METHOD This was a cross-sectional study comprising of 145,043 participants enrolled in the UK Biobank. Childhood trauma was determined by the Childhood Trauma Screener. Social health included social isolation, loneliness and emotional support. Outcomes of self-injurious thoughts and behaviors included suicide ideation, suicide attempt and non-suicidal self-injury (NSSI). Demographic data, self-reported morbidities and other confounding variables were covariates. Stata 17.0 and SPSS 27.0 was used to analysis data. RESULTS Compared with participants without childhood trauma, there was no protective effect of emotional support for NSSI in participants with childhood trauma (β-value difference = 0.334, p = 0.008). The risk effect of loneliness for suicide ideation, suicide attempt and NSSI were also weaker in participants experiencing childhood trauma (p<0.05). Social isolation was no longer a risk factor for NSSI in all participants, while loneliness remained as a threat (p < 0.05). LIMITATIONS Many variables were measured using core items of the scale in UK Biobank, meanwhile, the childhood trauma data collected in adulthood may have recall bias. CONCLUSIONS Adults reported childhood trauma were less vulnerable to self-injurious thoughts and behaviors when experiencing loneliness, but they could also not be protected from NSSI through emotional support. Emotional dysregulation caused by childhood trauma may contribute to this.

Associations between over-the-counter analgesics usage and symptoms of anxiety and depression in adolescents: a network analysis. BMC Psychiatry 2024; 24:366. [PMID: 38750535 PMCID: PMC11095036 DOI: 10.1186/s12888-024-05802-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Accepted: 04/29/2024] [Indexed: 05/19/2024] Open
Abstract
BACKGROUND The use of over-the-counter analgesics (OTCA) is common among adolescents and has been linked with increased symptoms of anxiety and depression. However, little is known about which specific symptoms are most strongly connected to OTCA usage. The current study assessed which anxiety and depression symptoms were most closely associated with OTCA usage in a large sample of adolescents and examined whether this differed across genders. METHOD The present study was based on data from 626,581 participants from the Ungdata survey in Norway. Associations between OTCA and anxiety and depression symptoms were examined using network analysis. Non-regularized partial-correlation networks were constructed to estimate the conditional dependent relations between the use of OTCA and symptoms while controlling for pain. Gender-specific networks were created for comparison. RESULTS OTCA usage was associated with most symptoms, even after controlling for pain, with the strongest associations with "sleep problems", "stiff or tense", "everything is a struggle" and "suddenly scared". There were some gender differences, showing that "sleep problems" and "hopeless" were more strongly related to OTCA usage in females, whereas "stiff or tense" was more strongly related to OTCA usage in males. CONCLUSION Overall, the somatic symptoms of anxiety and depression displayed the strongest associations with OTCA usage. When examining the gender-specific networks, both showed similar trends, although males exhibited slightly stronger associations between OTCA usage and somatic symptoms.

Longitudinal associations between loneliness, social isolation, and healthcare utilisation trajectories: a latent growth curve analysis. Soc Psychiatry Psychiatr Epidemiol 2024:10.1007/s00127-024-02639-9. [PMID: 38429539 DOI: 10.1007/s00127-024-02639-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2023] [Accepted: 02/12/2024] [Indexed: 03/03/2024]
Abstract
PURPOSE To explore the longitudinal associations between eight-year trajectories of loneliness, social isolation and healthcare utilisation (i.e. inpatient, outpatient, and nursing home care) in US older adults. METHODS The study used data from the Health and Retirement Study in 2006-2018, which included a nationally representative sample of American adults aged 50 and above (N = 6,832). We conducted latent growth curve models to assess the associations between trajectories of loneliness and isolation and healthcare utilisation over 8 years. RESULTS Independent of sociodemographic and health-related confounders, social deficits were associated with a lower likelihood of baseline physician visits (loneliness β= -0.15, SE = 0.08; social isolation β= -0.19, SE = 0.08), but there was a positive association between loneliness and number of physician visits (β = 0.06, SE = 0.03), while social isolation was associated with extended hospital (β = 0.07, SE = 0.04) and nursing home stays (β = 0.05, SE = 0.02). Longer nursing home stays also predicted better trajectories of loneliness and isolation over time. CONCLUSION Loneliness and social isolation are cross-sectionally related to complex patterns of different types of healthcare. There was no clear evidence that social deficits led to specific trajectories of healthcare utilisation, but nursing home stays may over time help provide social contact, supporting trajectories of isolation and potentially loneliness. Non-clinical services such as social prescribing could have the potential to address unmet social needs and further promote patients' health-seeking profiles for improving healthcare equity.

Co-occurrence of chronic pain and anxiety/depression symptoms in U.S. adults: prevalence, functional impacts, and opportunities. Pain 2024; 165:666-673. [PMID: 37733475 PMCID: PMC10859853 DOI: 10.1097/j.pain.0000000000003056] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 08/08/2023] [Accepted: 08/09/2023] [Indexed: 09/23/2023]
Abstract
ABSTRACT Co-occurrence of chronic pain and clinically significant symptoms of anxiety and/or depression is regularly noted in the literature. Yet, little is known empirically about population prevalence of co-occurring symptoms, nor whether people with co-occurring symptoms constitute a distinct subpopulation within US adults living with chronic pain or US adults living with anxiety and/or depression symptoms (A/D). To address this gap, this study analyzes data from the 2019 National Health Interview Survey, a representative annual survey of self-reported health status and treatment use in the United States (n = 31,997). Approximately 12 million US adults, or 4.9% of the adult population, have co-occurring chronic pain and A/D symptoms. Unremitted A/D symptoms co-occurred in 23.9% of US adults with chronic pain, compared with an A/D prevalence of 4.9% among those without chronic pain. Conversely, chronic pain co-occurred in the majority (55.6%) of US adults with unremitted A/D symptoms, compared with a chronic pain prevalence of 17.1% among those without A/D symptoms. The likelihood of experiencing functional limitations in daily life was highest among those experiencing co-occurring symptoms, compared with those experiencing chronic pain alone or A/D symptoms alone. Among those with co-occurring symptoms, 69.4% reported that work was limited due to a health problem, 43.7% reported difficulty doing errands alone, and 55.7% reported difficulty participating in social activities. These data point to the need for targeted investment in improving functional outcomes for the nearly 1 in 20 US adults living with co-occurring chronic pain and clinically significant A/D symptoms.

There but not really involved: The meanings of loneliness for people with chronic illness. Soc Sci Med 2024; 343:116596.

Abstract
Loneliness is one of the most pressing and rapidly growing contemporary social challenges around the world. Yet we still lack a good understanding of how loneliness is constituted and experienced by those most affected. We conducted semi-structured interviews with 40 people with chronic illness who were experiencing loneliness to explore what loneliness means to them and how it impacts in their daily lives. Drawing on ideas around liquidity and performativity, we identified the relational, temporal and social layers of loneliness. Our analysis revealed the interconnectedness of chronic illness and loneliness in participants' daily lives, as well as how chronic illness shifts temporal orientation, and transforms interpersonal relationships and relationship with self, contributing to the experiences of loneliness. Though participants described the many social conditions that restricted their opportunities for social participation, giving them a sense of being left behind and spectating the social life of others, a rhetoric of loneliness as a problem and responsibility of the individual was still prominent. A narrative of the need to perform social connection emerged in the absence of meaningful social bonds with others. We argue that normative ideals of wellness and positivity circulating in chronic illness communities and society more broadly are implicated in the experience of loneliness for people with chronic conditions. We conclude by considering how more expansive representations of how to live well with chronic illness may be important in reducing personal and collective loneliness.

Abstract
Chronic pain (CP) is a common and often debilitating disorder that has major social and economic impacts. A subset of patients develop CP that significantly interferes with their activities of daily living and requires a high level of healthcare support. The challenge for treating physicians is in preventing the onset of refractory CP or effectively managing existing pain. To be able to do this, it is necessary to understand the risk factors, both genetic and environmental, for the onset of CP and response to treatment, as well as the pathogenesis of the disorder, which is highly heterogenous. However, studies of CP, particularly pain with neuropathic characteristics, have been hindered by a lack of consensus on phenotyping and data collection, making comparisons difficult. Furthermore, existing cohorts have suffered from small sample sizes meaning that analyses, especially genome-wide association studies, are insufficiently powered. The key to overcoming these issues is through the creation of large consortia such as DOLORisk and PAINSTORM and biorepositories, such as UK Biobank, where a common approach can be taken to CP phenotyping, which allows harmonisation across different cohorts and in turn increased study power. This review describes the approach that was used for studying neuropathic pain in DOLORisk and how this has informed current projects such as PAINSTORM, the rephenotyping of UK Biobank, and other endeavours. Moreover, an overview is provided of the outputs from these studies and the lessons learnt for future projects.

The associations among childhood trauma, loneliness, mental health symptoms, and indicators of social exclusion in adulthood: A UK Biobank study. Brain Behav 2023; 13:e2959. [PMID: 36922902 PMCID: PMC10097065 DOI: 10.1002/brb3.2959] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/24/2022] [Revised: 02/17/2023] [Accepted: 02/28/2023] [Indexed: 03/18/2023] Open
Abstract
AIMS Childhood trauma has been associated with adult psychosocial outcomes linked to social exclusion. However, the strength of these associations in the general population is unknown. The emergence of the UK Biobank, with rich phenotypic characterization of the adult population, affords the exploration of the childhood determinants of adult psychopathology with greater statistical power. The current study aims to explore (1) the associations between childhood trauma and social exclusion in adulthood and (2) the role that self-reported loneliness and symptoms of distress play in the associations. METHODS This study was an analysis of 87,545 participants (mean [± SD] age = 55.68 [7.78], 55.0% female, 97.4% White) enrolled in the UK Biobank. Childhood trauma was determined by the five-item Childhood Trauma Screener. Current loneliness and symptoms of anxiety (Generalized Anxiety Disorder Scale-7) and depression (Patient Health Questionnaire-9) were also entered in analyses. Outcomes were "limited social participation," "area deprivation," "individual deprivation," and "social exclusion" from a previously determined dimensional measure of social exclusion in the UK Biobank. RESULTS Hierarchical multiple regression models indicated small associations between childhood trauma and social exclusion outcomes, explaining between 1.5% and 5.0% of the variance. Associations weakened but remained significant when loneliness, anxiety, and depression were entered in the models; however, anxiety symptoms demonstrated a negative association with "individual deprivation" and "social exclusion" in the final models. Depression was most strongly associated with "individual deprivation," "area deprivation," and "social exclusion" followed by childhood trauma. Loneliness was most strongly associated with "limited social participation." CONCLUSIONS Experiences of childhood trauma can increase the propensity for adulthood social exclusion. Loneliness and symptoms of depression attenuate but do not eliminate these associations. Anxiety symptoms have a potentially protective effect on the development of "individual deprivation." Findings add to the growing body of literature advocating for trauma-informed approaches in a variety of settings to help ameliorate the effects of childhood trauma on adult psychosocial outcomes. Further research, however, is required.

Eveningness intensifies the association between musculoskeletal pain and health-related quality of life: a Northern Finland Birth Cohort Study 1966. Pain 2022; 163:2154-2161.

Abstract
ABSTRACT People with an evening (E)-type preference (ie, chronotype) experience musculoskeletal (MSK) pain and reduced health-related quality of life (HRQoL) more often than morning (M) types. Musculoskeletal pain is a well-established contributor to reduced HRQoL. This study aimed to evaluate whether eveningness amplifies the association between MSK pain and HRQoL in contrast to morningness. Questionnaire data on MSK pain dimensions (intensity, disability at work, number of pain sites [NPSs], and frequency), chronotype, covariates (sex, sufficiency of sleep duration, mental distress, and presence of coexisting diseases), and HRQoL (measured by 15D) were collected among 46-year-old individuals belonging to the Northern Finland Birth Cohort 1966 (N = 4257). Individuals without any MSK pain were excluded. General linear models were conducted to estimate the associations between chronotypes, MSK pain dimensions, and HRQoL. The interaction terms (chronotype × pain dimension) were tested in the models. There were 13% E-types and 43% M-types in the study sample. Each pain dimension and chronotype were related to HRQoL. In the sex-adjusted chronotype-specific models, the reduction in HRQoL in relation to pain appeared to be stronger among E-types than among M-types in respect to all pain dimensions. After adjustments, this was particularly seen in terms of NPS and pain frequency. Our findings suggest that eveningness intensifies the association between MSK pain and HRQoL, and, thus, they are indicative of E-types being more sensitive than M-types to the consequences of MSK pain. As such, MSK pain treatment and rehabilitation actions to improve HRQoL should be especially targeted at E-types.

Abstract
Background Social well-being of patients with inflammatory bowel disease (IBD) is garnering increased attention; however, the impact of social isolation remained poorly understood. Objectives We investigated the joint association of social isolation and IBD with premature deaths to articulate the profound impact of social isolation in IBD prognosis. Design Longitudinal cohort study. Methods We leveraged data of 486,014 participants from UK Biobank (including 5791 with IBD), the mean follow-up was 11.84 years. Diagnoses of IBD and its subtypes of Crohn's disease (CD) and ulcerative colitis were confirmed with the combination of self-reporting, primary care, and hospital admission data. Social isolation was measured by the frequency of meeting family/friends, leisure and social activity, and communal/solitary living. Mortality was ascertained through data linkage with national death registries. Multivariable Cox regression models were conducted to estimate hazard ratio (HR) and 95% confidence interval (CI). Results Comparing non-isolated non-IBD population, the HRs of mortality in patients with IBD who were socially isolated or not were 2.06 (95% CI: 1.69, 2.51) and 1.33 (95% CI: 1.21, 1.45), respectively. The excess risk of death was observed in socially isolated patients with IBD (HR = 1.69, 95% CI: 1.36, 2.11), particularly among patients with CD (HR = 2.06, 95% CI: 1.48, 2.87) than their non-isolated counterparts. Data from subgroup and sensitivity analyses were consistent with those from the primary analysis. Conclusion Socially isolated patients with IBD especially CD increases the risk of premature death. Preventing social isolation might be a promising approach to improve IBD prognosis. Plain language summary Social isolation as a risk factor to excess mortality in patients with IBD: findings from a longitudinal cohort study Social isolation is prevalent in individuals with inflammatory bowel disease (IBD); however, its potential health impact on IBD prognosis has not been quantitatively well examined. In this study, we explored the association between social isolation and subsequent death, with the focus on patients with IBD.We leveraged data of 486,014 participants (including 5791 with IBD) from UK Biobank. We measured social isolation by the frequency of meeting family/friends, leisure and social activity, and communal/solitary living. We ascertained patients with IBD and mortality by self-report data and data linkage with primary care, hospital, and national death registry. Participants were followed up for a mean of 11.84 years.Comparing non-isolated non-IBD population, we found that patients with IBD who were deemed as socially isolated or not were associated with a 2.06-fold (1.69-2.51) and 1.33-fold (1.21-1.45) risk of death, respectively. Furthermore, we revealed that socially isolated patients with IBD and subtype Crohn's disease (CD) had 69% (36-111%) and 106% (48-187%) increased risk of premature death compared with their non-isolated counterparts, respectively.Social isolation merits attention in IBD care and management. Patients with IBD, especially CD, are more likely to be affected when socially isolated. Targeted social support strategies ought to be devised to improve IBD prognosis.

Introversion, Extraversion, and Worsening of Chronic Pain Impact during Social Isolation: A Mediation Analysis. J Clin Psychol Med Settings 2022:10.1007/s10880-022-09901-9.

Abstract
COVID-19 social distancing mandates increased social isolation, resulting in changes in pain severity and interference among individuals with chronic pain. Differences in personality (e.g., introversion/extraversion) may modulate responses to social isolation. We examined the influence of introversion on reported social distancing-related increases in pain interference and assessed for mediators of this relationship. Individuals with chronic pain (n = 150) completed validated questionnaires 4–8 weeks after implementation of social distancing mandates. Introversion/extraversion was measured using a subscale of the Myers-Briggs Type Indicator and changes in pain and psychosocial variables were calculated by comparing participants’ recalled and current scores. Association between introversion/extraversion and other variables were assessed using linear regression. A parallel mediation was used to examine mediators of the association between introversion and change in pain interference. Higher introversion was associated with a decrease in pain interference after social distancing (Rho = − .194, p = .017). Parallel mediation analysis revealed that the relationship between introversion/extraversion and change in pain interference was mediated by changes in sleep disturbance and depression, such that higher introversion was associated with less isolation-induced sleep disruption and depression, and thereby less worsening of pain interference. These findings suggest that personality factors such as introversion/extraversion should be considered when personalizing treatment of chronic pain.

Abstract
Personality is a strong determinant for several health-related behaviours and has been linked to the development of cardiovascular diseases. However, the reports of personality's mediating role have been inconsistent with no data available from large population-based cohorts. The study aimed to create proxies for the Big Five personality traits, extraversion, agreeableness, conscientiousness, openness and neuroticism, to examine the longitudinal relationship between personality and myocardial infarction in the UK Biobank. The study sample comprised of 484,205 participants (55% female, 45% male, mean age 56.4 ± 8.1 years) from UK Biobank cohort with a mean follow-up of 7 years. The personality proxies sociability, warmth, diligence, curiosity and nervousness were created using self-reported data on psychological factors, mental health and social support, to match the facets of the Big Five traits. As neuroticism is the only Big Five personality trait available in the UK Biobank, it was included to validate the personality proxies. Myocardial infarction outcome information was collected from hospital records, death registries or was self-reported. Logistic regression and Cox proportional hazard regression were used to estimate odds ratio (OR) and hazard ratios (HR), respectively with 95% confidence intervals (CI) adjusted for demographics (age, sex, socioeconomic status, ethnicity), health-related factors (BMI, diabetes, systolic and diastolic blood pressure) and lifestyle factors (alcohol intake, smoking, and moderate-to-vigorous physical activity). Diligence was found to be significantly associated with lower prevalent myocardial infarction [OR: 0.87; (CI 0.84-0.89)] and lower incident myocardial infarction [HR: 0.88; (CI 0.85-0.92)]. Sociability was also protective against prevalent [OR: 0.89; (CI 0.87-0.92)] and incident [HR: 0.90; (CI 0.87-0.93)] myocardial infarction. Conversely, nervousness inferred a higher risk for both prevalent [OR: 1.10; (CI 1.08-1.12)] and incident [HR: 1.07; (CI 1.04-1.09)] myocardial infarction during follow-up. Sex-stratified analyses revealed that nervousness significantly increases the risk for incident myocardial infarction among women [HR: 1.13; (CI 1.08-1.19)] compared to men [HR: 1.05; (CI 1.02-1.08)]. By using our created proxies, we were able to investigate the impact of personality on the development of myocardial infarction. Persons with higher levels of diligence and sociability mimicking predominantly conscientiousness and extraversion personalities respectively are less likely to experience myocardial infarction, while personalities predominantly characterised by nervousness pose higher risk for developing myocardial infarction. These initial findings invite further validation of the use of the personality proxies in UK Biobank cohort.

Abstract
OBJECTIVE This study aimed to characterize the current prevalence of loneliness, and the relation between loneliness severity and mental and physical health conditions, suicidality, and functional measures in a predominantly older sample of U.S. military veterans. METHODS This cross-sectional study used data from the National Health and Resilience in Veterans Study, which surveyed a nationally representative sample of U.S. veterans (N = 4,069; mean age = 62) from November 2019 through March 2020. Veterans were classified into one of 3 groups based on their current level of loneliness (hardly ever, sometimes, often) on an adapted version of the Revised UCLA Loneliness Scale. A comprehensive range of mental and physical health, and functioning variables were assessed using valid and reliable self-report assessments. RESULTS A total of 56.9% of veterans endorsed feeling lonely sometimes (37.2%) or often (19.7%). Loneliness severity was independently associated with a range of mental health (odds ratios [ORs] = 1.21-33.30), physical health (ORs = 1.21-6.80), and functional difficulties (d's = 0.09-0.59). Relative to hardly ever feeling lonely, feeling lonely often or sometimes was associated with a more than 12- and three-fold greater likelihood of current suicidal ideation (29.0% versus 7.3% versus 1.5%), even after adjustment for sociodemographic, military, and psychiatric risk factors. CONCLUSIONS Loneliness is highly prevalent in U.S. military veterans, with more than half endorsing feeling lonely sometimes or often, and 1-of-5 reporting feeling lonely often. Loneliness severity was independently associated with a broad range of mental and physical health and functional measures, ias well as suicidal ideation. Results underscore the importance of loneliness as a transdiagnostic prevention and intervention target in the U.S. veteran population.

IL-6 and hsCRP in Somatic Symptom Disorders and related disorders. Brain Behav Immun Health 2021; 9:100176.

Abstract
Interleukin 6 (IL-6) and high-sensitivity C-reactive protein (hsCRP) are biomarkers of systemic low-grade inflammation (SLI) in depression and anxiety. The question if SLI in those conditions is related to comorbid chronic medical conditions has not been resolved. DSM-5 Somatic symptom disorders and related disorders (SSRD) are conditions with serious distress related to physical symptoms as main criterion. They can occur in patients with medically unexplained symptoms (MUS) and in patients with known comorbid chronic medical conditions. Often, comorbid depression and anxiety are present. SSRDs offer the opportunity to explore the role of SLI in relation to mental distress, including trauma, MUS, chronic medical conditions and comorbid mental disorder. AIM We hypothesized that increased IL-6 and hsCRP may be directly linked to SLI in SSRD, and that comorbid chronic medical conditions, childhood trauma, current stress and comorbid depression and anxiety may be risk factors that account for some of the variance of SLI in SSRD. METHODS We explored these relationships in a large sample of 241 consecutive outpatients with SSRD. RESULTS Mean hsCRP level was 3.66 mg/l, and mean IL-6 level was 3.58 pg/ml. IL-6 and hsCRP levels were associated with each other: τ = 0.249, p < .001; a medium size correlation. Comorbid chronic medical conditions, adverse childhood events other than sexual trauma, and current stress levels were not associated with IL-6 or hsCRP levels. CONCLUSION IL-6 and hsCRP are elevated in SSRD, indicating SLI in SSRD independently of comorbid chronic medical conditions. In clinical research, elevated IL-6 and hsCRP can be used as biomarkers of SLI and can indicate risk for childhood sexual abuse in SSRD. Elevated hsCRP may be a biomarker indicating risk for comorbid depression or high pain levels in SSRD as well.

Prominent health problems, socioeconomic deprivation, and higher brain age in lonely and isolated individuals: A population-based study. Behav Brain Res 2021; 414:113510. [PMID: 34358570 DOI: 10.1016/j.bbr.2021.113510] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 07/09/2021] [Accepted: 07/31/2021] [Indexed: 01/12/2023]
Abstract
Loneliness is linked to increased risk for Alzheimer's disease, but little is known about factors potentially contributing to adverse brain health in lonely individuals. In this study, we used data from 24,867 UK Biobank participants to investigate risk factors related to loneliness and estimated brain age based on neuroimaging data. The results showed that on average, individuals who self-reported loneliness on a single yes/no item scored higher on neuroticism, depression, social isolation, and socioeconomic deprivation, performed less physical activity, and had higher BMI compared to individuals who did not report loneliness. In line with studies pointing to a genetic overlap of loneliness with neuroticism and depression, permutation feature importance ranked these factors as the most important for classifying lonely vs. not lonely individuals (ROC AUC = 0.83). While strongly linked to loneliness, neuroticism and depression were not associated with brain age estimates. Conversely, objective social isolation showed a main effect on brain age, and individuals reporting both loneliness and social isolation showed higher brain age relative to controls - as part of a prominent risk profile with elevated scores on socioeconomic deprivation and unhealthy lifestyle behaviours, in addition to neuroticism and depression. While longitudinal studies are required to determine causality, this finding may indicate that the combination of social isolation and a genetic predisposition for loneliness involves a risk for adverse brain health. Importantly, the results underline the complexity in associations between loneliness and adverse health outcomes, where observed risks likely depend on a combination of interlinked variables including genetic as well as social, behavioural, physical, and socioeconomic factors.

Meaning in Life Among Patients With Chronic Pain and Suicidal Ideation: Mixed Methods Study. JMIR Form Res 2021; 5:e29365. [PMID: 34003136 PMCID: PMC8214181 DOI: 10.2196/29365] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Revised: 05/06/2021] [Accepted: 05/16/2021] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Patients with chronic pain have elevated risk of suicidal ideation and behavior, including suicide attempts and completed suicides. In most studies, associations between chronic pain and suicidal ideation/suicidal behavior are robust even after adjusting for the effect of sociodemographics and psychiatric comorbidity. However, to refine the risk profile of these patients, further exploration of other possible risk and protective factors is necessary. OBJECTIVE There is a common clinical observation that experiencing chronic pain often requires a revision of life goals and expectations, and hence, it impacts the existential domain including one's perception of the meaning in life (MiL). This study aimed to characterize the main domains that constitute the personal MiL, including the "presence of" and "search for" constructs, in a group of patients with chronic pain and suicidal ideation. METHODS Seventy participants were enlisted by ongoing recruitment through a larger project anchored in daily clinical practice at the Multidisciplinary Pain Center of the Geneva University Hospitals. It was an observational mixed method study. Data were recorded through both validated quantitative questionnaires and qualitative open-ended questions. RESULTS The total sample consisted of 70 patients. Responses to questionnaires showed a depressive episode in 68 (97%) patients and anxious disorders in 25 (36%) patients. With a score threshold for positive MiL of 24, the mean score for the "presence of" construct was 20.13 (SD 8.23), and 63% (44/70) of respondents had a score <24. The mean score for the "search for" construct was lower at 18.14 (SD 8.64), and 70% (49/70) of respondents had a score <24. The "presence of" and "search for" constructs were significantly positively correlated (R=0.402; P=.001). An open question addressed the "presence of" construct by inviting the respondents to cite domains they consider as providing meaning in their life at the present time. All patients responded to this question, citing one or more domains. The three main dimensions that emerged from content analysis of this qualitative section were as follows: the domain of relationships, the domain of personal activities, and pain and its consequences on MiL. CONCLUSIONS The study results provide insights into patients with chronic pain and suicidal ideation, including the domains that provide them with meaning in their lives and the impact of pain on these domains with regard to suicidal ideation. The main clinical implications concern both prevention and supportive/psychotherapeutic interventions. They are based on a narrative approach aiming to explore with the patients the content of their suffering and the MiL domains that they could identify to mitigate it, in order to restructure/reinforce these domains and thus possibly reduce suicidal ideation. Specifically, a focus on maintaining the domains of interpersonal relationships and personal activities can allow patients to ultimately escape the biopsychosocial vicious cycle of chronic pain-induced deep moral suffering.

Modelling the Economic Impact of Reducing Loneliness in Community Dwelling Older People in England. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18041426. [PMID: 33546496 PMCID: PMC7913744 DOI: 10.3390/ijerph18041426] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/28/2020] [Revised: 01/28/2021] [Accepted: 01/30/2021] [Indexed: 01/01/2023]
Abstract
Loneliness has been associated with poor mental health and wellbeing. In England, a 2018 national strategy on loneliness was published, and public health guidelines recommend participation in social activities. In the absence of existing economic evidence, we modelled the potential cost effectiveness of a service that connects lonely older people to social activities against no-intervention. A 5-year Markov model was constructed from a health and social care perspective. Parameters were drawn from the literature, with the intervention structure based on an existing loneliness alleviation programme implemented in several settings across England. Univariate and probabilistic sensitivity analyses were undertaken. The total expected cost per participant in the intervention group is £ 7131 compared to £ 6783 in the usual care group with 0.45 loneliness free years (LFY) gained. The incremental cost per LFY gained is £ 768; in the probabilistic sensitivity analysis the intervention is cost saving in 3.5% of iterations. Potentially such interventions may be cost-effective but are unlikely to be cost-saving even allowing for sustained effects and cumulative adverse health and social care events averted. Empirical studies are needed to determine the cost-effectiveness of these interventions, ideally mapping changes in loneliness to the quality of life, in order to allow the key metric in health economic studies, cost per quality adjusted life year to be estimated.

The default network of the human brain is associated with perceived social isolation. Nat Commun 2020; 11:6393. [PMID: 33319780 PMCID: PMC7738683 DOI: 10.1038/s41467-020-20039-w] [Citation(s) in RCA: 85] [Impact Index Per Article: 21.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2020] [Accepted: 10/14/2020] [Indexed: 01/01/2023] Open
Abstract
Humans survive and thrive through social exchange. Yet, social dependency also comes at a cost. Perceived social isolation, or loneliness, affects physical and mental health, cognitive performance, overall life expectancy, and increases vulnerability to Alzheimer's disease-related dementias. Despite severe consequences on behavior and health, the neural basis of loneliness remains elusive. Using the UK Biobank population imaging-genetics cohort (n = ~40,000, aged 40-69 years when recruited, mean age = 54.9), we test for signatures of loneliness in grey matter morphology, intrinsic functional coupling, and fiber tract microstructure. The loneliness-linked neurobiological profiles converge on a collection of brain regions known as the 'default network'. This higher associative network shows more consistent loneliness associations in grey matter volume than other cortical brain networks. Lonely individuals display stronger functional communication in the default network, and greater microstructural integrity of its fornix pathway. The findings fit with the possibility that the up-regulation of these neural circuits supports mentalizing, reminiscence and imagination to fill the social void.
