Loneliness among older European adults: results from the survey of health, aging and retirement in Europe

Young adults with vision impairment in India: Loneliness and social networks

PURPOSE

To examine the prevalence of loneliness and associated factors in young adults with vision impairment (VI), including quality of life (QoL) in India.

METHODS

Two hundred and three VI young adults (18-35 years) and 219 age-matched non-VI (controls) adults completed the loneliness scale, WHOQOL-BREF, Social Network Index (SNI) (network diversity, people in network size and number of embedded network subscales) and questions regarding sociodemographic characteristics and independent mobility. Rasch analysis was used to validate the questionnaires and interval-level scores were generated. Generalised linear models were used to estimate independent associations of sociodemographic factors, VI characteristics, social networks and QoL with loneliness.

RESULTS

The prevalence of moderate and severe loneliness in the VI group was 10% (95% CI: 6.5, 15.4) and 4.4% (95% CI: 2.0, 8.2), respectively, and higher than that of controls. The VI group had a worse loneliness score than controls (-1.66 ± 2.25 vs. -2.13 ± 1.85 logits; p = 0.03). Those with ≤12 years and >12 years of education had loneliness scores of -1.58 ± 2.45 and -1.82 ± 1.99 logits, respectively (p = 0.01). Compared with controls, the VI group reported fewer extended family members, neighbours and friends leading to significantly smaller networks and network diversity (all p < 0.001). Loneliness scores demonstrated a significant correlation with only two SNI subscales for both groups: people in network size (r = -0.28 for VI; r = -0.30 for non-VI; p < 0.001 for both) and number of embedded networks (r = -0.22 for VI; r = -0.21 for non-VI; p = 0.002 for both). Both education (β = 0.45; p = 0.04) and QoL (β = -0.27, p = 0.02) were predictors of loneliness.

CONCLUSIONS

Loneliness was commonly experienced by young VI adults and was higher among those with lower levels of education. Loneliness decreased with the presence of a larger number of people in network, suggesting that interventions to increase social activity and participation may be valuable in young VI adults.

The association between loneliness with health service use and quality of life among informal carers in Australia

OBJECTIVE

The demanding nature of caregiving and limited social support can lead to informal carers experiencing loneliness, which can impact their well-being and overall health service use (HSU). The study aims to examine the association between loneliness with HSU and Health state utility values among informal carers in Australia.

METHODS

Data were derived from three waves (2009, 2013, and 2017) of the nationally representative longitudinal Household Income and Labour Dynamics of Australia (HILDA) survey, focusing on adult informal carers. Outcome measures included visits to the General Practitioner, the number of hospital admissions, and the SF-6D score. Generalized Estimating Equations (GEE) analysis was conducted to explore the associations between loneliness and HSU, as well as loneliness and utility values (based on SF-6D) while adjusting for age, sex, education, marital status, income, and physical/mental health conditions.

RESULTS

After controlling for covariates, lonely carers reported lower utility values (IRR = 0.91, 95%CI [0.89, 0.93], p < 0.001) compared to non-lonely carers. Lonely carers reported a higher number of GP visits (IRR = 1.18, 95% CI [1.04, 1.36], p < 0.05) as well as a higher likelihood of visiting specialists (AOR = 1.31, p = 0.046) and hospital doctors (AOR = 1.42, p = 0.013) compared to the non-lonely carers.

CONCLUSIONS

The findings of this study highlight the relationship between loneliness on both healthcare utilization and carers' overall well-being. Addressing loneliness through targeted interventions and social support systems can help improve health outcomes and potentially reduce the overall healthcare costs among informal carers in Australia.

Loneliness prevalence of community-dwelling older adults and the impact of the mode of measurement, data collection, and country: A systematic review and meta-analysis

OBJECTIVES

The aim of this systematic review and meta-analysis is to assess the prevalence of loneliness in many countries worldwide which have different ways of assessing it.

DESIGN

Systematic review and meta-analysis.

SETTING

We searched seven electronic databases for English peer-reviewed studies published between 1992 and 2021.

PARTICIPANTS

We selected English-language peer-reviewed articles, with data from non-clinical populations of community-dwelling older adults (>60 years), and with "loneliness" or "lonely" in the title.

MEASUREMENTS

A multilevel random-effects meta-analysis was used to estimate the prevalence of loneliness across studies and to pool prevalence rates for different measurement instruments, data collection methods, and countries.

RESULTS

Our initial search identified 2,021 studies of which 45 (k = 101 prevalence rates) were included in the final meta-analysis. The estimated pooled prevalence rate was 31.6% (n = 168,473). Measurement instrument was a statistically significant moderator of the overall prevalence of loneliness. Loneliness prevalence was lowest for single-item questions and highest for the 20-item University of California-Los Angeles Loneliness Scale. Also, differences between modes of data collection were significant: the loneliness prevalence was significantly the highest for face-to-face data collection and the lowest for telephone and CATI data collection. Our moderator analysis to look at the country effect indicated that four of the six dimensions of Hofstede also caused a significant increase (Power Distance Index, Uncertainty Avoidance Index, Indulgence) or decrease (Individualism) in loneliness prevalence.

CONCLUSIONS

This study suggests that there is high variability in loneliness prevalence rates among community-dwelling older adults, influenced by measurement instrument used, mode of data collection, and country.

Relationship between loneliness and internet addiction: a meta-analysis

BACKGROUND

In the digital age, the Internet has become integrated into all aspects of people's work, study, entertainment, and other activities, leading to a dramatic increase in the frequency of Internet use. However, excessive Internet use has negative effects on the body, psychology, and many other aspects. This study aims to systematically analyze the research findings on the relationship between loneliness and Internet addiction to obtain a more objective, comprehensive effect size.

METHODS

This study employed a comprehensive meta-analysis of empirical research conducted over the past two decades to investigate the relationship between loneliness and Internet addiction, with a focus on the moderating variables influencing this relationship. This meta-analysis adopted a unique approach by categorizing moderating variables into two distinct groups: the objective characteristics of research subjects and the subjective characteristics of researchers. It sheds light on the multifaceted factors that influence the relationship between loneliness and Internet addiction.

RESULTS

A literature search in web of science yielded 32 independent effect sizes involving 35,623 subjects. Heterogeneity testing indicated that a random effects model was appropriate. A funnel plot and Begg and Mazumdar's rank correlation test revealed no publication bias in this meta-analysis. Following the effect size test, it was evident that loneliness was significantly and positively correlated with Internet addiction (r = 0.291, p < 0.001). The moderating effect analysis showed that objective characteristics significantly affected the relationship. However, subjective characteristics did not affect the relationship.

CONCLUSIONS

The study revealed a moderately positive correlation between loneliness and Internet addiction. Moreover, this correlation's strength was found to be influenced by various factors, including gender, age, grade, and the region of the subjects. However, it was not affected by variables such as the measurement tool, research design, or research year (whether before or after COVID-19).

Senior volunteers: addressing loneliness in times of COVID-19

Volunteering in old age plays an important role in addressing feelings of loneliness, but little research has been conducted on the impact of engaging in volunteering activities during the COVID-19 pandemic. This study investigates the longitudinal impact of volunteering on feelings of loneliness. We analyzed data from 31,667 adults aged 50 years and older in the Survey of Health, Ageing and Retirement in Europe (SHARE), across three consecutive waves (one before the pandemic and two during the COVID-19 pandemic). Binary logistic regression analyses were conducted for loneliness, using volunteering and several control variables as independent variables, and found that even after controlling for previous loneliness, volunteering has a protective effect against experiencing feelings of loneliness. Those who participated in volunteering activities before or during the second pandemic period had a lower risk of loneliness during the second pandemic period. Volunteering during the second pandemic period, before and during the second pandemic period, and during all three periods measured in the study was negatively associated with the odds of feeling lonely. Encouraging volunteering among older adults can be a useful strategy to prevent loneliness during future emergency situations like the COVID-19 outbreak.

Predictors of loneliness onset and maintenance in European older adults during the COVID-19 pandemic

Objectives

Loneliness is a major public health concern. Duration of loneliness is associated with severity of health outcomes, and further research is needed to direct interventions and social policy. This study aimed to identify predictors of the onset vs. the maintenance of loneliness in older adults before and during the pandemic using longitudinal data from the Survey of Health, Age, and Retirement in Europe (SHARE).

Methods

Groupings of persistent, situational, and no loneliness were based on self-reports from an ordinary pre-pandemic SHARE wave and a peri-pandemic telephone interview. Predictors were identified and compared in three hierarchical binary regression analyses, with independent variables added in blocks of geographic region, demographics, pre-pandemic social network, pre-pandemic health, pandemic-related individual, and country level variables.

Results

Self-reported loneliness levels for the persistent, situational, and no loneliness groups were stable and distinct through 7 years preceding the pre-pandemic baseline measure. Shared predictors were chronic diseases, female sex, depression, and no cohabitant partner. Persistent loneliness was uniquely predicted by low network satisfaction (OR: 2.04), functional limitations (OR: 1.40), and a longer country-level isolation period for older adults (OR: 1.24).

Conclusion

Interventions may target persons with depression, functional limitations, chronic health issues, and no cohabitant partner. The added burden of the length of isolation on those who are already lonely should be taken into account when employing social policies that target older adults. Further research should distinguish between situational and persistent loneliness, and seek to identify predictors of chronic loneliness onset.

Helps you, helps me? Provision of instrumental and personal care and loneliness among adults aged 50 years and older during the COVID-19 pandemic

PURPOSE

To examine the association between provision of instrumental and personal care, and loneliness in adults aged 50 years and older during the COVID-19 pandemic. Instrumental care referred to the provision of assistance with obtaining necessary or essential products and/or services, whereas personal care referred to the assistance with daily life activities or the provision of emotional support. Social capital and caregiver stress theories served as the study's theoretical framework.

MATERIALS AND METHODS

The data were obtained from the two COVID-19 waves of the Survey of Health, Ageing, and Retirement in Europe (SHARE) conducted in 2020 and 2021. The data were analyzed using logistic regression models. The analytical sample consisted of 48,722 adults in the abovementioned age bracket residing in Europe and Israel.

RESULTS

Providing instrumental care negatively related to loneliness. Providing instrumental care to a single category of people negatively related to loneliness, whereas providing personal care to multiple categories of people positively related to loneliness. Providing personal care to children positively related to loneliness.

CONCLUSIONS

The results suggest that different types of care provision correspond differently to the experience of loneliness while partially supporting both theoretical frameworks. Moreover, care indicators correspond differently to loneliness. The results imply that for a better understanding of the link between care provision and loneliness in later life, various parameters as well as various types of care provision should be examined.

Isolation or Replenishment? The Case of Partner Network Exclusivity and Partner Loss in Later Life

OBJECTIVES

People's partners and spouses often provide a wide range of essential emotional and practical support. As crucial as they may be, a nontrivial segment of the older population appears to limit close discussions to their partner alone, a phenomenon we term "partner network exclusivity." This network structure could leave people vulnerable to partner losses and subsequent social isolation. The present research has 3 aims: (a) examine the prevalence of partner-exclusive networks among European older adults; (b) consider who is most likely to inhabit such networks; and (c) investigate whether and how individuals in such precarious networks rebalance them in case of partner losses.

METHODS

The analysis uses Wave 4 (2011) and Wave 6 (2015) of the Survey of Health, Ageing and Retirement in Europe (SHARE) to perform logistic regression on one's possession of partner-exclusive networks and the addition of core ties.

RESULTS

More than a quarter of partnered respondents (28.1%) are in partner-exclusive core networks. Men, childless individuals, and those with financial difficulties are most likely to occupy such networks. Individuals in partner exclusivity are especially likely to enlist additional ties upon partner loss. Nevertheless, men and individuals at early old age are relatively unlikely to rebalance their core networks in case of partner death.

DISCUSSION

This study provides new evidence that network replenishment following relationship disruptions is plausible even for those from precarious network settings. Nevertheless, widowhood produces patterns of vulnerability for a subset of older adults in partner-exclusive core networks.

Exploring associations of older adults with virtual nature: a randomised factorial online survey

Loneliness and social isolation are important social determinants of wellbeing of older adults. Conversational exchanges can promote connectedness between older adults, however, conversations may not always come easy. Research shows that exposure to nature-based stimuli such as pictures and videos can stimulate social aspirations and trigger associations that could facilitate conversations, in particular when nature scenery is perceived as fascinating, mysterious, spacious and suited for social interaction. Therefore, this study investigated whether exposure to these nature characteristics (high versus low) lead to associations that could act as conversational material. A randomised factorial design, using a virtual reality-based approach for experimental control, led to 17 different virtual representations of nature (VN). In total, 150 participants (60 years and older) were recruited for an online survey. Spontaneous associations were coded on personal engagement and valence. The number of associations was measured with one multiple-choice question. VN exposure successfully triggered personally engaging and positively valenced associations and were related to multiple associations, in particular when the VN were high on mystery. Furthermore, positive effects of VN exposure was more pronounced for participants with high (rather than low) levels of nature relatedness and many (rather than few) available nature opportunities. These findings indicate that VN exposure provides fertile ground for conversations as a means to promote connectedness and social wellbeing of older adults.

Life Events and Loneliness Among Older Women of Diverse Sexual Identities: Application of the Stress Process Model

Loneliness among older adults has been a topic of interest in recent years. We analyse four waves of data from the Australian Longitudinal Study on Women's Health. We estimate growth models to examine differences in loneliness trajectories from age 50 for women who identify as exclusively heterosexual, plurisexual (bisexual, mainly heterosexual, mainly lesbian) and exclusively lesbian. We find no significant differences in levels of loneliness across sexual identity groups at age 50. We find that while loneliness trajectories of exclusively heterosexual women trend down, levels of loneliness increase with age among plurisexual women. Adverse health events and relationship problems increase loneliness to a greater extent among plurisexual women compared to exclusively heterosexual and exclusively lesbian women. Our results suggest older lesbian women may have accumulated social or personal resources or developed coping mechanisms over the courses of their lives, while plurisexual women remain a vulnerable group.

Relationships between Interpersonal Goals and Loneliness in Older Adults: A Cross-Sectional Study

Loneliness is linked to many physiological and psychological issues and disproportionately affects older adults. Interpersonal goals (compassion and self-image) are essential to interpersonal relationships; however, how they relate to loneliness in older adults is unknown. We investigated the impact of interpersonal goals on loneliness using the Ecosystem-Egosystem Theory of Social Motivation. This study, adopting a descriptive cross-sectional correlational design, used data from the 2016 Health and Retirement Study. Participants (n = 3212) included people aged >65 years (mean age: 75; female: 60.1%). We performed exploratory factor analysis with principal axis factoring and varimax rotation to examine the suitability of compassionate and self-image goals as separate factors. The complex samples general linear model was used to assess the relationship between loneliness and interpersonal goals. Interpersonal goals were significantly negatively associated with loneliness. Respondents with higher compassion and self-image goals reported lower loneliness levels. Our results contribute to understanding how interpersonal goals relate to loneliness in older adults. These initial findings warrant further investigation.

Loneliness and Mental Health in Response to Early and Late COVID-19 Outbreak: A Cross-Sectional Study of Czech Adults Aged 50 and Over

The unpredictable spread of the COVID-19 pandemic, national lockdowns, and public health measures implemented in the Czech Republic had a negative effect on older adults' mental health and loneliness. The 2,631 older adults in 2020 and 2,083 older adults in 2021 used in this study formed a nationally representative sample of the Survey of Health, Ageing and Retirement in Europe (SHARE). Almost every third older adult experienced feelings of loneliness in both stages of the COVID-19 outbreak. Loneliness increased in 2021 in those individuals who reported their physical health as poor, who felt nervous, sad or depressed, and who had ever left their home since the outbreak. According to age-related drivers of loneliness, feelings of loneliness were prevalent (40% vs. 45%) among younger retirees in both waves. In both data sets, declared feelings of sadness or depression were the strongest sustainable predictor of loneliness (2020 and 2021 models, OR = 3.69; 95% CI [2.90, 4.69] and OR = 2.55; [1.97, 3.30]). Being a woman and feeling nervous equated with a higher likelihood of feeling lonely compared to counterparts. Policy makers should therefore aim to carefully improve psychosocial and health-related consequences faced by this vulnerable population during the pandemic and beyond.

Loneliness across time and space

People feel lonely when their social needs are not met by the quantity and quality of their social relationships. Most research has focused on individual-level predictors of loneliness. However, macro-level factors related to historical time and geographic space might influence loneliness through their effects on individual-level predictors. In this Review, we summarize empirical findings on differences in the prevalence of loneliness across historical time and geographical space and discuss four groups of macro-level factors that might account for these differences: values and norms, family and social lives, technology and digitalization, and living conditions and availability of individual resources. Regarding historical time, media reports convey that loneliness is on the rise, but the empirical evidence is mixed, at least before the COVID-19 pandemic. Regarding geographical space, national differences in loneliness are linked to differences in cultural values (such as individualism) but might also be due to differences in the sociodemographic composition of the population. Research on within-country differences in loneliness is scarce but suggests an influence of neighbourhood characteristics. We conclude that a more nuanced understanding of the effects of macro-level factors on loneliness is necessary because of their relevance for public policy and propose specific directions for future research.

Changes in loneliness prevalence and its associated factors among Bangladeshi older adults during the COVID-19 pandemic

Aims

Worldwide, loneliness is one of the most common psychological phenomena among older adults, adversely affecting their physical and mental health conditions during the COVID-19 pandemic. This study aims to assess changes in the prevalence of loneliness in the two timeframes (first and second waves of COVID-19 in Bangladesh) and identify its correlates in pooled data.

Methods

This repeated cross-sectional study was conducted on two successive occasions (October 2020 and September 2021), overlapping with the first and second waves of the COVID-19 pandemic in Bangladesh. The survey was conducted remotely through telephone interviews among 2077 (1032 in the 2020-survey and 1045 in the 2021-survey) older Bangladeshi adults aged 60 years and above. Loneliness was measured using the 3-item UCLA Loneliness scale. The binary logistic regression model was used to identify the factors associated with loneliness in pooled data.

Results

We found a decline in the loneliness prevalence among the participants in two survey rounds (51.5% in 2021 versus 45.7% in 2020; P = 0.008), corresponding to 33% lower odds in the 2021-survey (AOR 0.67, 95% CI 0.54–0.84). Still, nearly half of the participants were found to be lonely in the latest survey. We also found that, compared to their respective counterparts, the odds of loneliness were significantly higher among the participants without a partner (AOR 1.58, 95% CI 1.20–2.08), with a monthly family income less than 5000 BDT (AOR 2.34, 95% CI 1.58–3.47), who lived alone (AOR 2.17, 95% CI 1.34–3.51), with poor memory or concentration (AOR 1.58, 95% CI 1.23–2.03), and suffering from non-communicable chronic conditions (AOR 1.55, 95% CI 1.23–1.95). Various COVID-19-related characteristics, such as concern about COVID-19 (AOR 1.28, 95% CI 0.94–1.73), overwhelm by COVID-19 (AOR 1.53, 95% CI 1.14–2.06), difficulty earning (AOR 2.00, 95% CI 1.54–2.59), and receiving routine medical care during COVID-19 (AOR 2.08, 95% CI 1.61–2.68), and perception that the participants required additional care during the pandemic (AOR 2.93, 95% CI 2.27–3.79) were also associated with significantly higher odds of loneliness. However, the odds of loneliness were significantly lower among the participants with formal schooling (AOR 0.71, 95% CI 0.57–0.89) and with a family of more than four members (AOR 0.76, 95% CI 0.60–0.96).

Conclusions

The current study found a decreased prevalence of loneliness among Bangladeshi older adults during the ongoing pandemic. However, the prevalence is still very high. The findings suggest the need for mental health interventions that may include improving social interactions increasing opportunities for meaningful social connections with family and community members and providing psychosocial support to the vulnerable population including older adults during the pandemic. It also suggests that policymakers and public health practitioners should emphasise providing mental health services at the peripheral level where the majority of older adults reside.

Teaming up to traverse loneliness: a co-creative journey toward a home care work model for supporting social participation among older adults

Background

Participatory research is particularly suitable in adressing know-do gaps in health systems. There is a disparity between what is known about the benefits of social participation and home care’s responsibility to provide conditions amenable to older adults’ social participation, and what is accomplished in home care practice. Home care workers are a large, low-power group, whose competences should be better harnessed. We carried out a participatory action research (PAR) project with the goal of generating an improved structure for identifying and alleviating loneliness. This article aims to explore the co-creative process of designing a work model that guides home care workers in supporting social participation among older care recipients.

Methods

Multimodal data from 16 PAR workshops with 14 home care workers were described and explored through the ‘recursive PAR process’ and the ‘framework for occupational enablement for change in community practice”.

Results

The PAR process is outlined through the objectives, activities, and work model, as well as enablement strategies employed throughout the PAR process; as are its opportunities, challenges and implications. The work model describes how care workers can act as discoverers of care recipients’ unmet social needs, employ intentional communication, and link to relevant professions or community services to alleviate loneliness among older home care recipients.

Conclusions

This research process included opportunities of collaborating with enthusiastic and competent home care workers, but also challenges of moving between theory and practice and maintaining active participation between workshops. The resulting work model is in step with the requirements of elderly care, is unique in its field and could comprise a first step toward a more systematic approach of assessing and addressing loneliness. The vivid delineation of the PAR process provided in this paper can aid other researchers in navigating participatory research in home care contexts.

The micro-macro interplay of economic factors in late-life loneliness: Evidence from Europe and China

Individual socioeconomic status has a significant impact on whether older adults can initiate and maintain social relationships and participate in society, hence it affects loneliness. At the macro level, income inequality is expected to increase the risk of loneliness by eroding social cohesion and trust, while welfare generosity might protect people from loneliness. The aim of the study is to explore whether income inequality and welfare generosity at the country level moderate the effect of socioeconomic status at the individual level on late-life loneliness. Data were obtained from the HRS family of surveys - the Survey of Health, Aging and Retirement in Europe (SHARE) (wave 5, 2011/12) and China Health and Retirement Longitudinal Study (CHARLS) (wave 2, 2012/13). Respondents aged 50 years and older from twelve European countries and China were included in the study. Logistic country fixed effect models were used in the analysis. The findings show a stronger effect of individual socioeconomic status on late-life loneliness in more income-unequal societies and a weaker effect in more welfare-generous societies. There is a need to consider the impact of income distribution and welfare spending on the risk of loneliness among those older adults with low socioeconomic status when tailoring preventive programs and interventions to reduce loneliness among this vulnerable group.

Loneliness and diurnal cortisol levels during COVID-19 lockdown: the roles of living situation, relationship status and relationship quality

Loneliness and social isolation have become increasing concerns during COVID-19 lockdown through neuroendocrine stress-reactions, physical and mental health problems. We investigated living situation, relationship status and quality as potential moderators for trait and state loneliness and salivary cortisol levels (hormonal stress-responses) in healthy adults during the first lockdown in Germany. N = 1242 participants (mean age = 36.32, 78% female) filled out an online questionnaire on demographics, trait loneliness and relationship quality. Next, N = 247 (mean age = 32.6, 70% female) completed ecological momentary assessment (EMA), collecting twelve saliva samples on 2 days and simultaneously reporting their momentary loneliness levels. Divorced/widowed showed highest trait loneliness, followed by singles and partnerships. The latter displayed lower momentary loneliness and cortisol levels compared to singles. Relationship satisfaction significantly reduced loneliness levels in participants with a partner and those who were living apart from their partner reported loneliness levels similar to singles living alone. Living alone was associated with higher loneliness levels. Hierarchical linear models revealed a significant cross-level interaction between relationship status and momentary loneliness in predicting cortisol. The results imply that widowhood, being single, living alone and low relationship quality represent risk factors for loneliness and having a partner buffers neuroendocrine stress responses during lockdown.

Childlessness and social and emotional loneliness in middle and later life

Despite theoretical accounts asserting the importance of children for the wellbeing of individuals as they age, research evidence suggests that children may be inconsequential when it comes to loneliness. Yet, there is reason to expect some subgroups may be more vulnerable to the impact of childlessness than others and this may also differ depending on the type of loneliness being assessed. This paper addresses the relationship between childlessness and social and emotional loneliness in middle and later life, including differential vulnerability associated with age, gender and marital/partner status. The study drew on data from three waves (2007, 2012 and 2018) of the Canadian General Social Survey for a nationally representative sample of adults aged 45 and older (N = 49,892). In general, childlessness assumed greater importance with regard to social than emotional loneliness. Women reported lower levels of social loneliness in conjunction with childlessness than men. Further, childlessness was associated with higher levels of overall and social loneliness among older than middle-aged adults. Fewer interactions were evident between marital/partner status and childlessness. Among women specifically, those who were co-habiting, separated/divorced or never married reported lower levels of social loneliness than their married counterparts. In contrast, childlessness was linked to greater emotional loneliness only among separated/divorced men and widowed women. Overall, our results suggest that having children available does matter for feelings of loneliness in middle and later life but that the relationship varies and is contingent on the social contexts (age, gender, marital/partner status) and the type of loneliness (social, emotional) involved.

Loneliness among older adults in Europe: The relative importance of early and later life conditions

The aim of this paper is to study the association between childhood circumstances and loneliness in older adults in Europe. Based on rich information collected by the Survey on Health, Ageing, and Retirement in Europe (SHARE) on childhood characteristics and individual characteristics at age 50+, the study is able to control for personality traits, socioeconomic and demographic factors, social support and health in later life, and country-specific characteristics. The analyses show strong correlations between life circumstances in childhood and feeling lonely in older age; these correlations remain significant after adjusting for covariates. While ill health is the main factor correlated with loneliness at 50+, as expected, the analysis of the relative importance of the determinants reveals that personality traits account for more than 10% of the explained variance and that life circumstances during childhood account for 7%. Social support at older ages is the second highest category of factors, accounting for 27%-with, interestingly, support at home and social network characteristics contributing about 10% each, engaging in activities and computer skills accounting for 7% of the explained variance. Demographic and socioeconomic factors account for 6% and country-level characteristics contribute 5%. This paper points out the relevance of early life interventions to tackling loneliness in older age, and it shows that early interventions and interventions aiming at increasing social support in later life need to be adapted to all personality types. Thus, the role of childhood circumstances and the mechanisms explaining the association between loneliness in childhood and loneliness in later life deserve more attention in future research.

The impact of changing social support on older persons' onset of loneliness during the COVID-19 pandemic in the UK

BACKGROUND AND OBJECTIVES

Social distancing measures aimed at controlling the spread of COVID-19 are likely to have increased social isolation amongst those over 70 instructed to shield at home. This study examines the incidence of loneliness by gender over the first ten months of the COVID-19 pandemic among persons aged 70 and above in the UK, and the impact of changing social networks and perceived social support on the new occurrence of loneliness.

RESEARCH DESIGN AND METHODS

Participants (N=1,235) aged 70 and over with no reports of loneliness before the pandemic who participated in seven rounds of the Understanding Society: COVID-19 Study (April 2020-January 2021) and the main Understanding Society study conducted during 2019. Cox regression analysed the time to a new occurrence of loneliness.

RESULTS

Among older people who hardly ever/never felt lonely before the pandemic, 33.7% reported some degree of loneliness between April 2020-January 2021. Living in a single-person household, having received more social support before the pandemic, changes in support receipt during the pandemic and a deteriorating relationship with one's partner during the pandemic increased the risk of experiencing loneliness. Older women were more likely than older men to report loneliness, even when living with a partner.

DISCUSSION AND IMPLICATIONS

During the three COVID-related lockdowns in the UK, changes in older people's social networks and support resulted in a significant onset of loneliness. Findings highlight the risks of shielding older persons from COVID-19 in terms of their mental well-being and the importance of strengthening intergenerational support.

The Association Between Loneliness and Inflammation: Findings From an Older Adult Sample

Loneliness has been linked to poor mental and physical health outcomes. Past research suggests that inflammation is a potential pathway linking loneliness and health, but little is known about how loneliness assessed in daily life links with inflammation, or about linkages between loneliness and inflammation among older adults specifically. As part of a larger investigation, we examined the cross-sectional associations between loneliness and a panel of both basal and LPS-stimulated inflammatory markers. Participants were 222 socioeconomically and racially diverse older adults (aged 70-90 years; 38% Black; 13% Hispanic) systematically recruited from the Bronx, NY. Loneliness was measured in two ways, with a retrospective trait measure (the UCLA Three Item Loneliness Scale) and an aggregated momentary measure assessed via ecological momentary assessment (EMA) across 14 days. Inflammatory markers included both basal levels of C-reactive protein (CRP) and cytokines (IL-1β, IL-4, IL-6, IL-8, IL-10, TNF-α) and LPS-stimulated levels of the same cytokines. Multiple regression analyses controlled for age, body-mass index, race, and depressive symptoms. Moderation by gender and race were also explored. Both higher trait loneliness and aggregated momentary measures of loneliness were associated with higher levels of CRP (β = 0.16, p = 0.02; β = 0.15, p = 0.03, respectively). There were no significant associations between loneliness and basal or stimulated cytokines and neither gender nor race were significant moderators. Results extend prior research linking loneliness with systemic inflammation in several ways, including by examining this connection among a sample of older adults and using a measure of aggregated momentary loneliness.

Close ties, near and far away: patterns and predictors of geographic network range among older Europeans

A growing number of older adults maintain connections in their core discussion networks at variant distances, raising concerns about the lack of discussants in proximity and the consequences on their social life. This study examines the typical geographic layouts for aging Europeans' core discussion networks and their implications for network function and quality. With a sample of community-dwelling respondents aged 50 and above from the Survey of Health, Aging, and Retirement in Europe, the present research identifies seven geographic layouts that extend previously identified family and diverse network types by adding spatial nuance. Individuals in mid-range and distant-family networks typically lack a discussant nearby but sustain high emotional closeness with family discussants at a distance and express high overall satisfaction with their network. Proximate-diverse networks with a strong representation of non-kin members nearby turn out to be less advantageous than prior research might suggest, providing relatively frequent contact but the lowest level of network satisfaction. Results also identify how individual characteristics link to the geographic layouts and describe their prevalence across European regions. Overall, relatively dispersed layouts are common for older adults across multiple countries and do not necessarily indicate lower emotional closeness and network satisfaction. The present study highlights the importance of looking beyond the mere presence of proximate connections in older adults' core networks.

Risk factors for loneliness among older people in a Nordic regional context – a longitudinal study

The aim of this study was to examine the prevalence of loneliness among older people and to identify risk factors for loneliness in a Nordic regional context over a six-year period. Longitudinal data from the Gerontological Regional Database (GERDA) study of 4,269 older adults living in northern Sweden and western Finland, aged 65, 70, 75 and 80 at baseline in 2010, were analysed. Logistic regressions were used to analyse socio-demographic, social and health-related risk factors at baseline and changes in these for experiences of loneliness at follow-up. The results showed that most older adults (85%) did not experience loneliness at baseline or at follow-up in our study region. However, 3 per cent of the sample reported loneliness in both study years, indicating enduring and chronic loneliness. Analyses revealed that being widowed and becoming a widow/er as well as poor self-rated health at baseline and the onset of depression were risk factors for loneliness. Finally, the risk of loneliness was higher in older people living in Sweden. Further work is needed to explore changes and stability in loneliness as well as to increase our understanding of between-country differences in loneliness.

Compensatory Connections? Living Alone, Loneliness, and the Buffering Role of Social Connection among older American and European Adults

OBJECTIVE

The growth of solo living has important implications for the rising "loneliness epidemic" among older adults. This study considered whether two forms of social connectedness-extra-household core discussion networks and social participation-buffer the loneliness associated with living alone.

METHOD

Our study used data from two surveys (National Social Life, Health, and Aging Project; Survey of Health, Ageing and Retirement in Europe) encompassing 20 developed Western countries in 2009/2010 and 2015/2016 (n = 110,817). Harmonizing measures across data sets, we estimated survey-specific and pooled longitudinal regression models with interaction terms.

RESULTS

High levels of social connectedness only moderately buffered the loneliness associated with living alone in later life. Findings were largely consistent across regions of Europe and the United States, though the buffering patterns were most robustly identified for widowed solo dwellers.

DISCUSSION

Extra-household connections are partial compensators, but do not seem to fully replace the ready companionship afforded by residential co-presence in later life. Future research is needed to understand whether the efficacy of compensatory connections differs by gender, race/ethnicity, and across more diverse global regions.

Loneliness Among US Adults Aged ≥55 Early in the COVID-19 Pandemic : Findings From the COVID-19 Coping Study

OBJECTIVES

Loneliness is associated with increased risks of adverse health outcomes among middle-aged and older adults. We estimated the prevalence of loneliness and identified key sociodemographic, employment, living, and health-related risk factors for loneliness among adults aged ≥55 during the early phase of the COVID-19 pandemic in the United States, when much of the country was under shelter-in-place orders.

METHODS

We collected data from online questionnaires in the COVID-19 Coping Study, a national study of 6938 US adults aged ≥55 from April 2 through May 31, 2020. We estimated the population-weighted prevalence of loneliness (scores ≥6 of 9 on the 3-item UCLA Loneliness Scale), overall and by sociodemographic, employment, living, and health-related factors. We used population-weighted modified Poisson regression models to estimate prevalence ratios (PRs) and 95% CIs for the associations between these factors and loneliness, adjusting for age, sex, race, ethnicity, and education level.

RESULTS

Overall, we estimated that 29.5% (95% CI, 27.9%31.3%) of US adults aged ≥55 were considered high in loneliness in April and May 2020. In population-weighted adjusted models, loneliness was the most prevalent among those who reported depression, who were not married or in a relationship, who lived alone, and who were unemployed at the onset of the pandemic.

CONCLUSIONS

We identified subpopulations of middle-aged and older adults who were vulnerable to loneliness during a period when COVID-19 shelter-in-place orders were in place across most of the country. These insights may inform the allocation of resources to mitigate an unintended health consequence during times of restricted activity.

Three-item loneliness scale: psychometric properties and normative data of the Spanish version

Loneliness is a common social phenomenon across countries with negative effects in health. Thus, the measurement of loneliness is of paramount importance. The Three-Item Loneliness Scale (TILS) was designed to be used in large-population surveys as a quick measure of loneliness. The aim of this study is to provide a Spanish validation of the TILS. A representative sample of the Spanish population (N = 1951) was used. We analysed the psychometric properties, factor structure, and distribution demographics characteristics of the Spanish TILS. Analyses showed differences regarding age, gender, educational level, employment status, household composition and annual gross income in line with previous literature. The confirmatory factor analysis revealed a unifactorial structure, with significant moderate correlations between the TILS and depression, anxiety, paranoia and well-being, and mild significant correlations with belongingness and mistrust. The internal consistency of the Spanish TILS was good (α = 0.82). Our study indicates that the TILS is a valid and reliable measure of loneliness in the Spanish population. Loneliness is a modern epidemic and a precursor of mental and health problems that reduced the quality of life. Therefore, it is important to have reliable measures of this phenomenon.

Social inequality and the risk of living in a nursing home: implications for the COVID-19 pandemic

Across EU countries, all available evidence suggests that the number of deaths linked to COVID-19 among those living in nursing homes has been extremely high. However, it is largely unknown to what extent income and education affect the probability of being a nursing home resident. If the probability of residing in a nursing home is stratified by socio-economic status, under the current COVID-19 pandemic socio-economic inequality in the probability of living in a nursing home could contribute to enlarge socio-economic inequalities in the risk of mortality with COVID-19. In this article, we investigate whether there are income and educational differences in the likelihood of being a resident in a nursing home across 12 European countries. We use SHARE data (waves 5-7) and compute logistic regression models for rare events. We find that low-educated individuals and those having household income below the national median are more likely to live in a nursing home. This general pattern holds across all the European countries considered. However, there is considerable uncertainty in our estimates due to a small sample size, and firm conclusions on how the effect of socio-economic characteristics varies across countries cannot be drawn. Still, there is some indication that educational and income differences are the largest in the Scandinavian countries (Denmark and Sweden) and the Netherlands, while the smallest ones are found in Italy, with the remaining countries laying in between.

The Effect of Labor and Relationship Exclusions on Older Korean Men with Depression

To manage depression of older men, it is necessary to identify factors that influence depression and improve them. This study used the Korean Aging Longitude Research to understand the effects of labor exclusion and relationship exclusion on depression in Korean male seniors aged 65 and older. According to research on the effect of labor exclusion and relationship exclusion on depression, depression in the case where labor was excluded was 1.69 times higher in 2014, 1.65 times higher in 2016, and 1.93 times higher in 2018 compared to the case where labor was not excluded. Depression in the case where relationship was excluded was 2.94 times higher in 2014, 3.15 times higher in 2016, and 2.57 times higher in 2018 compared to the case where relationship was not excluded. Depression in the case where labor and relationship were both excluded was 3.00 times higher in 2014, 3.23 times higher in 2016, and 2.81 times higher in 2018 compared to the case where neither labor nor relationship was excluded. Since labor exclusion and relationship exclusion have a big influence on depression in older men, it is necessary to establish plans for job creation and for the formation of social relationships for the elderly.

Worry about debt is related to social loneliness in older adults in the Netherlands

The amount of financial debt held by older adults has grown substantially over the past two decades in Europe. This study examines the association of objective and subjective debt burden with social and emotional loneliness among 1,606 older adults in the Netherlands. Objective debt burden is based on financial terms, such as debt-to-income ratio; whereas subjective debt burden measures the psychological distress caused by financial debt. Data are from the 2015/2016 wave of the Longitudinal Aging Study Amsterdam. First, we use means-comparison tests to examine whether older adults who experience social and emotional loneliness differ from older adults who do not experience loneliness regarding their subjective and objective debt burdens. Subsequently, using linear regression models we address two questions: whether social loneliness and emotional loneliness are associated with objective and subjective debt burden; and whether social participation, social network size, anxiety and depression mediate these relationships. We find that subjective debt burden (i.e. the worry related to debt) is a significant predictor of social loneliness, above and beyond the role of social and psychological measures. Objective debt burden, in contrast, is unrelated to social and emotional loneliness. Social participation, social network size, anxiety and depression do not mediate the debt-burden-to-loneliness relationships. The results point to the importance of subjective debt burden in understanding social loneliness and designing interventions.

Gender differential in low psychological health and low subjective well-being among older adults in India: With special focus on childless older adults

BACKGROUND

Gender and health are two factors that shape the quality of life in old age. Previous available literature established an associaton between various demographic and socio-economic factors with the health and well-being of older adults in India; however, the influence of childless aged is neglected. Therefore, the study examined the gender differential in psychological health and subjective well-being among older adults, focusing on childless older adults.

METHODOLOGY

This study utilized data from Building a Knowledge Base on Population Aging in India (BKPAI). Psychological health and subjective well-being were examined for 9541 older adults aged 60 years & above. Descriptive statistics and bivariate analysis were used to find the preliminary results. Further, multivariate analysis has been done to fulfill the objective of the study.

RESULTS

Around one-fifth (21.2%) of the men reported low psychological health, whereas around one-fourth (25.5%) of the women reported low psychological health. Further, around 24 per cent of men and 29 per cent of women reported low subjective well-being. Results found that low psychological well-being (OR = 1.87, C.I. = 1.16-3.01), as well as low subjective well-being (OR = 1.78, C.I. = 1.15-2.76), was higher in childless older women than in childless older men. Higher education, community involvement, good self-rated health, richest wealth quintile, and residing in urban areas significantly decrease the odds of low subjective well-being and low psychological well-being among older adults.

CONCLUSION

There is a need to improve older adults' psychological health and subjective well-being through expanded welfare provisions, especially for childless older adults. Moreover, there is an immediate requirement to cater to the needs of poor and uneducated older adults.

Similarities and Differences of Mental Health in Women and Men: A Systematic Review of Findings in Three Large German Cohorts

In Germany, large, population-based cohort studies have been implemented in order to identify risk and protective factors for maintaining health across the life span. The purpose of this systematic review is to analyse findings from three large ongoing cohorts and to identify sex-specific prevalence rates, risk and protective factors for mental health. Published studies from the Cooperative Health Research in the Region Augsburg (KORA), the Study of Health in Pomerania (SHIP) and the Gutenberg Health Study (GHS)), representing the southern, north-eastern and middle parts of Germany, were identified through searches of the databases PubMed and Web of Science. A total of 52 articles was identified from the start of each cohort until June 2019. Articles reporting prevalence rates of mental health [N = 22], explanatory factors for mental health [N = 25], or both [N = 5] were identified. Consistent across cohorts, higher prevalence rates of internalizing disorders were found for women and more externalizing disorders for men. Risk and protective factors for mental health included social factors, lifestyle, physical health, body mass index (BMI), diabetes, genetic and biological factors. In all areas, differences and similarities were found between women and men. The most evident were the sex-specific risk profiles for depression with mostly external risk factors for men and internal risk factors for women. Gender was not assessed directly, therefore we examined whether socioeconomic and family-related factors reflecting gender roles or institutionalized gender could be used as a proxy for gender. Overall, this systematic review shows differences and similarities in prevalence rates and determinants of mental health indicators between women and men. They underline the importance of focussing on sex specific approaches in mental health research and in the development of prevention measures. Current research on mental health still lacks focus on gender aspects. Therefore, an increased focus on sex and gender in mental health research is of great importance.

Personhood in aloneness and in affinity: satisfactory social participation among home care recipients

Background: Social participation can be described as engaging in activities that provide interaction with others, and support for social participation may reduce loneliness and improve health. However, there is limited knowledge about social participation in a home care context.Aim: To explore the perceptions and experiences of community-dwelling older adults with regard to aspects related to social participation in a home care context.Materials and methods: Seven home care recipients, aged 79-94 years, from two Swedish municipalities participated in semi-structured interviews. The interviews were analyzed using qualitative content analysis. Results: The study identified the central theme, Personhood in aloneness and in affinity, as important in accomplishing satisfactory social participation. The results incorporated cultivating personal interests and navigating occupations, as well as having one's needs seen and experiencing mutuality in social encounters.Conclusions: The study nuances existing knowledge about social participation among older home care recipients, and the findings strengthen the importance of framing a home care environment where recipients can cultivate personhood and be recognized as valuable individuals with relevant needs. Significance: This study extends current understandings of the variety and richness of the social participation and occupational engagement enjoyed by older home care recipients, to be considered in research and practice.

Mental wellbeing in the German old age population largely unaltered during COVID-19 lockdown: results of a representative survey

BACKGROUND

Older individuals are at increased risk of a severe and lethal course of COVID-19. They have typically been advised to practice particularly restrictive social distancing ('cocooning'), which has sparked much debate on the consequences for their mental wellbeing. We aimed to provide evidence by conducting a representative survey among the German old population during COVID-19 lockdown.

METHODS

A computer-assisted standardized telephone interview was conducted in a randomly selected and representative sample of the German old age population (n = 1005; age ≥ 65 years) during the first lockdown in April 2020. Assessments included sociodemographic factors, aspects of the personal life situation during lockdown, attitudes towards COVID-19, and standardized screening measures on depression, anxiety, somatization, overall psychological distress (Brief Symptom Inventory/BSI-18) and loneliness (UCLA 3-item loneliness scale). Sampling-weighted descriptive statistics and multiple multivariable regression analyses were conducted.

RESULTS

Participants were M = 75.5 (SD = 7.1) years old; 56.3% were women. At data collection, COVID-19 lockdown had been in force for M = 28.0 (SD = 4.8) days. Overall, older individuals were worried about COVID-19, but supportive of the lockdown. Mean BSI-18 scores were 1.4 for depression, 1.6 for anxiety and 2.2 for somatization as well as 5.1 for global psychological distress. These figures did not indicate worse mental wellbeing, given normative values established by studies before the pandemic (2.0, 1.6, 2.4, 6.0, respectively). The prevalence of loneliness was 13.1%, which also fell within a range of estimates reported by studies before the pandemic. There were only few significant associations of aspects of the personal life situation during lockdown and attitudes towards COVID-19 with mental wellbeing. Resilience explained a large amount of variance.

CONCLUSIONS

In the short-term, the mental wellbeing of the German old age population was largely unaltered during COVID-19 lockdown, suggesting resilience against the challenging pandemic situation. Our results refute common ageist stereotypes of "the weak and vulnerable older adults" that were present during the pandemic. Long-term observations are needed to provide robust evidence.

Are Loneliness and Social Isolation Associated with Quality of Life in Older Adults? Insights from Northern and Southern Europe

Purpose: Loneliness and social isolation have detrimental effects on health in old age; however, the prospective associations with quality of life (QoL) remain unclear. Furthermore, despite the existence of a European north-south gradient in the distribution of loneliness and social isolation, little is known whether the associations are context-specific. We investigated the relationships between loneliness, social isolation and QoL of older adults residing in the North (Sweden) and South (Spain) of Europe. Methods: Study sample consisted of 2995 Swedish and 4154 Spanish older adults who participated in waves six and seven of the Study on Health, Aging and Retirement in Europe (SHARE). Loneliness and social isolation were measured at the baseline, and QoL was measured at the baseline and follow-up using CASP-12. Prospective associations were assessed via multivariate linear regression. Results: In Sweden, subjects with higher vs. lower loneliness had 1.01 (95% CI: −1.55, −0.40) units lower QoL, while every standard deviation increase in social isolation was associated with a 0.27 (95% CI: −0.42, −0.09)-unit decrease in QoL. In Spain, every standard deviation increase in social isolation was associated with a 0.66 (95% CI: −1.11, −0.22)-unit decrease in QoL. The association was stronger in subjects aged ≤65 years old and those with no chronic diseases. The association with loneliness was not statistically significant in Spain. Conclusion: Loneliness and social isolation are prospectively associated with decreased QoL among older adults, yet the associations are contextually bound. Future interventions should target both exposures, among others, in order to increase QoL in this group.

Social participation and loneliness among older adults in Yazd, Iran

Social participation among older people is associated with more practice of physical activities, improvement of cognitive skills and less feeling of loneliness. The primary purpose of this cross-sectional study was to examine the social participation and sense of loneliness among older adults in Yazd, an Iranian city that is known for its traditional values and religious people. The non-probability sample consisted of 200 elderly people. Data collection tool was a questionnaire, which was completed by a trained interviewer through face-to-face interview. The mean scores of social participation and loneliness feeling among participants were 17.29 ± 5.62 (8-40) and 38.02 ± 7.91 (16-80), respectively. From the participants, 79.8% had not participated in educational cultural and activities. Mostly reported barriers to social participation included transportation-related issues (57%), diseases and health problems (43.5%) and personal or family responsibility (36%). The best predictors of loneliness were demographic characteristics, followed by the total number of diseases/problems and the total number of barriers to social participation. Social participation itself was not a statistically significant predictor of loneliness. Theoretical and practical implications were discussed.

Impact of the COVID-19 Pandemic on Loneliness Among Older Adults

The COVID-19 pandemic has created a pattern of everyday physical distancing worldwide, particularly for adults aged 65+. Such distancing can evoke subjective feelings of loneliness among older adults, but how this pandemic has influenced that loneliness is not yet known. This study, therefore, explored the association between subjective loneliness and different time phases of the COVID-19 pandemic to explain the pandemic's impact on loneliness among older adults. The analysis employed a sample of 1,990 community-dwelling older adults aged 65-95 (mean age = 72.74 years; 43% female) in Switzerland. Data collection occurred both before and after Switzerland's first confirmed COVID-19 case. Regression models allowed the researchers to determine the binary and multivariate effects of different pandemic time phases on loneliness. The descriptive analysis revealed that loneliness increased after the Swiss government recommended physical distancing and slightly decreased after the Federal Council decided to ease these measures. According to the multivariate analysis, women, lower-income individuals, individuals living alone, individuals with no children, individuals unsatisfied with their contact with neighbors, and individuals interviewed after the physical distancing recommendations were more likely to report greater loneliness. The results suggest the pandemic has affected older adults' subjective evaluations of their subjective loneliness, and these findings help illustrate the pandemic's outcomes.

Age differences in demographic, social and health-related factors associated with loneliness across the adult life span (19-65 years): a cross-sectional study in the Netherlands

BACKGROUND

Recognition of loneliness as a health concern among adults stresses the need to understand the factors associated with loneliness. Research into factors of influence in the various phases of the adult life span (19-65 years) is scarce. Therefore, the associations between demographic, social and health-related factors and loneliness among young (19-34 years), early middle-aged (35-49 years) and late middle-aged adults (50-65 years) were explored.

METHODS

A secondary analysis with a large cross-sectional dataset was performed. Data was collected from September to December 2016 in the Netherlands, by a self-report survey. Loneliness was measured using the De Jong-Gierveld Loneliness Scale. In total, 26,342 adults (19-65 years) participated (response rate: 34%). Multiple logistic regression analyses were performed to examine associations between demographic, social and health-related factors as independent variables, and loneliness as dependent variable among the three age groups.

RESULTS

Prevalence of loneliness among young, early and late middle-aged adults was 39.7, 43.3 and 48.2%, respectively. Living alone, frequency of neighbour contact, perceived social exclusion, psychological distress, psychological and emotional wellbeing were consistently associated with loneliness across the groups. The association between ethnicity and loneliness was stronger among young and early middle-aged adults, compared to late middle-aged adults. Young adults showed the strongest association between contact frequency with friends and loneliness. The strength of association between financial imbalance and loneliness gradually decreased from young to late middle-aged adults. Educational level was associated with loneliness among young adults only, while an association between employment status and loneliness was found solely among early middle-aged adults. For late middle-aged adults only, perceived health was associated with loneliness. Frequency of family contact was associated with loneliness, only among early and late middle-aged adults.

CONCLUSION

This study indicates that factors associated with loneliness across the adult life span may be understood from an age-normative life-stage perspective. Accordingly, there is no one-size-fits-all approach to reduce loneliness among adults, suggesting that a variety of interventions or an indirect approach may be necessary. Future research should focus on causal relations between factors and loneliness in different age groups, using a longitudinal research-design with, preferably, an even broader set of factors.

Loneliness is associated with risk of cognitive impairment in the Survey of Health, Ageing and Retirement in Europe

OBJECTIVES

To test whether loneliness is associated with the risk of cognitive impairment up to 11 years later in a European sample of middle-aged and older adults. The study examines whether this association is independent of measures of social isolation, depression, and other risk factors for cognitive impairment and dementia.

METHODS

Participants (N = 14 114) from the Survey of Health, Ageing and Retirement in Europe (SHARE) answered a single item on loneliness at baseline and were assessed for cognitive impairment every 2-to-3 years for 11 years. Participants who scored at least 1.5 standard deviations below the age-graded mean on both a memory recall task and verbal fluency task were classified as impaired. A three-item measure of loneliness was available for a sample of respondents followed up to 4 years.

RESULTS

Feeling lonely was associated with increased risk of incident cognitive impairment (HR = 1.31, 95%CI = 1.19-1.44), after accounting for age, sex, education, and SHARE country strata. The association was robust but reduced in magnitude when controlling for clinical and behavioral risk factors, health-related activity limitations, social isolation, social disengagement, and depressive symptoms. The association was not moderated by socio-demographic factors and was also apparent when using the three-item loneliness scale instead of the single-item measure.

CONCLUSIONS

These findings expand the extant literature on loneliness and the risk of cognitive impairment in older adulthood. Loneliness is one modifiable factor that can be intervened prior to the development of severe impairment or dementia.

The meanings of loneliness for older persons

Objectives: We identify and describe the meanings of loneliness among older persons, the kinds of relationships they are seeking in order to alleviate it, and the barriers they face in developing these connections.Method: Study participants were 35 older persons between the ages of 66 and 92 years from Tel Aviv, Israel, who participated in an intervention which involved group activities and individual meetings. The transcriptions of the individual meetings in which participants described their loneliness and explored potential solutions formed the data for thematic analysis.Results: Participants experienced loneliness in highly individualized ways. They were more likely to experience it when alone in the evening and on weekends, and when distracting activities were not available. While most sought companionship, many focused on a specific type of relationship, ranging from instrumental companionships to intimate and spousal relationships. Participants often had particular preferences about the demographic and socioeconomic characteristics they desired in a companion. Barriers to alleviating loneliness included cognitive sets, social skills deficits, rejection of others, technological illiteracy, and physical, sensory, and cognitive limitations. External factors included economic hardship and community programming which failed to promote socialization.Conclusion: New approaches are needed to counter and prevent loneliness among older persons by addressing the types of particular desires raised in our findings, as well as the psychological barriers to realizing them. Public policy and societal initiatives should tackle external barriers through programming which promotes social engagement and the development of other innovative strategies.

Longitudinal analysis of loneliness and inflammation at older ages: English longitudinal study of ageing

Loneliness has been associated with adverse health outcomes, including age-related diseases with an inflammatory etiology such as cardiovascular disease. We aimed to identify potential biological pathways linking loneliness with morbidity and mortality by examining associations of loneliness with biomarkers. Participants in the English Longitudinal Study of Ageing (n = 3239) aged 50 years or older with an average age of 64 years, provided data in waves 4 (2008/2009) and 6 (2012/2013). Linear regression conditional change models had three outcomes: C reactive protein (CRP) measured in mg/L (log transformed), fibrinogen in g/L and ferritin in g/dL. In men, the onset of loneliness indicated by answering 'no' at wave 4 and 'yes' at wave 6 to question "Much of the time during the past week, you felt lonely?" was associated with a statistically significant increase in levels of CRP (β = 0.36, 95% confidence interval (0.09 to 0.62)), plasma fibrinogen (0.18 (0.04 to 0.31)) and ferritin (41.04 (6.58 to 75.50)), after full adjustment. A statistically significant increase in CRP in men was also observed for onset of loneliness assessed with the question "How often do you feel lonely?" (0.20 (0.03 to 0.38)). These associations were not mediated by depressive symptoms. Persistent loneliness (loneliness experienced at both baseline and follow-up) assessed using the University of California Los Angeles (UCLA) loneliness scale was associated with an increase in CRP (0.11 (0.004 to 0.22)) among men. Associations of the two latter loneliness measures with fibrinogen and ferritin were mainly null. Among women, the only statistically significant association was for persistent loneliness (loneliness at both waves) identified by question "Much of the time during the past week, you felt lonely?" with a reduction in levels of ferritin (-20.62 (-39.78 to -1.46)). Men may be more susceptible to loneliness-associated disease risks signaled by biological changes, including systemic inflammation. Combined social and targeted medical interventions may help to reduce health risks associated with loneliness.
