Lonely at the bottom: a cross-sectional study on being ill, poor, and lonely

An exploratory study on material deprivation and loneliness among older adults in Hong Kong

BACKGROUND

Poverty, as a risk factor for loneliness, has been understudied, and there is a need to gain a better understanding of the relationship between poverty examined by material deprivation and loneliness among older adults in Hong Kong. It also aimed to explore the possible mediation and moderation effects of social support, social networks, neighborhood collective efficacy, and social engagement in the link between material deprivation and loneliness.

METHODS

1696 Chinese older adults aged 60 years and above (Mage = 74.61; SD = 8.71) participated in a two-wave study. Older adults reported their loneliness level, material deprivation, perceived level of social support, social network, neighborhood collective efficacy, social engagement, and sociodemographic information. Logistic regression was conducted to examine the effect of material deprivation on loneliness, as well as the mediation and moderation models.

RESULTS

The results indicated that material deprived older adults reported a significantly higher level of loneliness 2 years later when controlling for demographic variables, health-related factors, and loneliness at baseline. We also found that engagement in cultural activities partially mediated the effect of material deprivation and loneliness. Furthermore, neighborhood collective efficacy and engagement in cultural activities were significant moderators that buffer the relationship between material deprivation and loneliness.

CONCLUSIONS

Our results suggested the need to alleviate the negative impact of material deprivation on loneliness by developing interventions focused on promoting neighborhood collective efficacy and social engagement, which could be aimed at building meaningful bonds among Chinese older adults in Hong Kong.

Risk factors for loneliness: A literature review

RATIONALE

Increasingly, loneliness is being recognised as a serious problem with detrimental effects on health, as well as on social cohesion and community trust. To effectively tackle this complex issue, a clear understanding of the phenomenon and its main drivers is needed. Over years of scientific research on loneliness, many potential risk factors have emerged and been tested empirically.

OBJECTIVE

This narrative review of 109 studies provides a concise summary of empirical evidence on the main potential risk factors for loneliness and presents an additional section dedicated to the COVID-19 pandemic.

METHOD

Given the very large number of existing studies, emphasis is placed on recent meta-analyses and systematic literature reviews as well as longitudinal studies. Similarly, given the large number of possible risk factors for loneliness, which may differ based on the geographical and cultural context, this review focuses on studies from Europe and North America.

RESULTS

The results show that demographic factors often correlate with loneliness, but in many cases the link becomes negligible when controlling for other factors. Often, physical and mental health problems are found to be associated with loneliness, and so are some psychological factors, such as neuroticism or extroversion. Loneliness also depends on the environment in which one lives, and possibly the broader socio-economic and socio-cultural contexts. Nevertheless, the review shows that ultimately everything comes down to the quantity and quality of social relationships. In particular, marital status, living arrangements and the characteristics of one's personal social network are quite consistently found to be among the strongest predictors of loneliness. These main findings about the risk factors for loneliness remained valid also during the COVID-19 pandemic.

POLICY IMPLICATIONS

The findings of this review have implications for policy, as understanding who the most vulnerable groups are is key for designing targeted policy solutions that tackle loneliness.

Equal Opportunities in Aging: Income Level Moderates the Relationship Between Infrequent Participation in Formal Social Activities and Loneliness Among Older Adults

Infrequent participation in formal social activities among older adults increases the risk of loneliness. We examined whether a higher income level moderates the relationship between infrequent participation and loneliness. Utilizing data from wave #6 of the European Health, Aging, and Retirement Survey, we included participants aged 65+ (i.e., older adults), non-participants in the labor force (N = 24 819). Loneliness was measured by the R-UCLA loneliness questionnaire, formal social activity by participation frequency in volunteer/charity activities, educational course/training, sports/social/other clubs, and political/community organizations. Hierarchical multiple regression models examined relationships between variables, controlled by country. Infrequent participation in formal social activity associated with higher risk of loneliness. However, income moderated the association between participation and loneliness; infrequently participating older adults with low-to-moderate income were more vulnerable to loneliness than higher income older adults, for whom infrequent participation did not increase loneliness. This reinforces the need to encourage formal social activity with subsidy for low-to-moderate income older adults.

Two sides of the same coin? Absolute income and perceived income inadequacy as social determinants of health

BACKGROUND

Absolute income is commonly used in studies of health inequalities, however it does not reflect spending patterns, debts, or expectations. These aspects are reflected in measures concerning perceived income inadequacy. While health inequities by absolute income or perceived income inadequacy are well established, few studies have explored the interplay of absolute income and perceived income inadequacy in relation to health.

METHODS

Multiple data sources were linked into a nationally representative dataset (n = 445,748) of Dutch adults (18 +). The association between absolute income, perceived income inadequacy and health (self-reported health, chronic disease and psychological distress) was tested using logistic and Poisson regressions, controlling for various potential confounders (demographics, education) and mastery. Interactions were tested to check the association between perceived income inadequacy and health for different absolute income groups.

RESULTS

Perceived income inadequacy was reported at every absolute income group (with 42% of individuals in the lowest income group and 5% of individuals in the highest income group). Both absolute income and perceived income inadequacy were independently associated with health. The adjusted relative risk (RR) for lowest absolute income group is 1.11 (1.08-1.1.14) and 1.28 (1.24-1.32) for chronic disease and self-reported health respectively, and the Odds Ratio (OR) for psychological distress is 1.28 (1.16-1.42). For perceived income inadequacy the RR's were 1.41 (1.37-1.46) and 1.49 (1.44-1.54) and the OR for psychological distress is 3.14 (2.81-3.51). Mastery appeared to be an important mediator for the relationship between perceived income inadequacy, poor self-rated health and psychological distress.

CONCLUSIONS

Absolute income and perceived income inadequacy reflect conceptually different aspects of income and are independently associated with health outcomes. Perceived income inadequacy may be accounted for in health inequality studies, alongside measures of absolute income. In policy-making, targeting perceived income inadequacy might have potential to reduce health inequalities.

Measuring loneliness: Psychometric properties of the three-item loneliness scale among community-dwelling adults

Loneliness is a prevalent set of negative feelings associated with unsatisfactory and reduced social interactions, inadequate social support, poor satisfaction with life and health, negative emotions, and economic burden. Thus, its measurement is of foremost importance. Therefore, this study aimed (i) to devise the Portuguese version of the three-Item Loneliness Scale (T-ILS), which is ideal for epidemiological studies, and (ii) to evaluate its psychometric properties. Three hundred forty-five community-dwelling Portuguese adults with a mean age of 54.6 ± 19.5 years, 61.7% women, recruited door-to-door, were assessed with the Portuguese versions of T-ILS, Satisfaction With Life Scale-SWLS, Lubben Social Network Scale 6-items-LSNS-6, a question regarding Happiness/Unhappiness, and a sociodemographic questionnaire. The T-ILS showed good psychometric properties and correlated moderately with SWLS and LSNS-6, and happiness, and weakly with the number of people in the household. The Portuguese version of the T-ILS proved to be a valid and reliable instrument, easy and quick to administer. It proved to be a valuable tool in screening loneliness in Portugal, being potentially useful to the identification of lonelier people in need of intervention.

Effectiveness of a multicomponent intervention to reduce social isolation and loneliness in community-dwelling elders: A randomized clinical trial

AIMS

To assess the effect of a multicomponent intervention on reducing social isolation and loneliness and improving the quality of life in community-dwelling older adults.

DESIGN

A cluster-randomized controlled clinical trial.

METHODS

A total of 56 older adults participated in the control group and 63 older adults in the experimental group. The intervention consisted of 6 home-based face-to-face sessions, intercalated with 5 telephone calls and was conducted by nursing students and volunteer staff with experience in the subject. The study was conducted between April 2018 and December 2019. In terms of statistical analysis, several procedures were carried out: a statistical analysis per protocol and intention to treat, considering isolation, loneliness and quality of life as endpoints; a comparison of paired means, to analyse the behaviour of the outcome variables at baseline and the end of the study; and finally, a binary logistic regression analysis, considering social support as a dependent variable.

RESULTS

The study results do not show the effectiveness of the modified CARELINK programme, analysed as a whole, on the decrease in social isolation or loneliness or the improvement in HRQL. However, a detailed analysis of the behaviour of some of the variables during the study indicates some results that deserve to be commented on. Comparing the mean confidential support scores between the experimental and control group at the initial and final stages shows significant differences in the analysis by protocol, and close to statistical significance in the analysis by intention to treat. Comparing the paired means obtained in the experimental group, an improvement in emotional loneliness scores was found. Finally, the variables associated with the social support of the subjects at the end of the follow-up period were as follows: having people who help them and mobility.

CONCLUSION

Although the results obtained do not allow us to affirm that the intervention programme is effective, these same results point to improved confidential support and emotional loneliness in older adults participating in the intervention. Having people to help them and a greater degree of mobility are factors favouring the decrease in social isolation.

IMPACT

This study suggested that modified CARELINK, a multicomponent intervention performed by trained volunteers, could improve confidential support in community-dwelling older adults. It also reports the importance of considering the level of mobility and support networks as determinants of the improvement caused by the intervention.

Intersectional inequalities in loneliness among older adults before and during the early phase of the COVID-19 pandemic: A total population survey in the Swedish eldercare setting

Loneliness among older adults is a public health problem that has received particular attention since the emergence of the COVID-19 pandemic. Studies to date have however found a rather modest psychosocial impact of the pandemic on older adults, and scarce research has analyzed this impact using a comprehensive equity lens. The present study used an intersectional approach to examine social inequalities in loneliness before and during the early phase of the pandemic among older adults receiving eldercare in Sweden. The study population (analytical N = 205,529) came from two waves (2019 and 2020) of a total population survey to all older adult (>65 years of age) home care recipients and nursing home residents in Sweden. Loneliness was self-reported by a single-item measure, and survey data were linked to population register data on age, gender, residential setting, income, and country of birth. Additive binomial regression models were used to estimate prevalence differences and discriminatory accuracy according to an analysis of individual heterogeneity and discriminatory accuracy (AIHDA) approach. Results showed inequalities in loneliness arising particularly in the intersection of country of birth, income, and residential setting. The inequalities widened slightly but ubiquitously following the emergence of the pandemic in 2020, with particularly nursing home residents emerging as a risk group. The discriminatory accuracy of inequalities was consistently low to moderate throughout the analyses but increased marginally during the pandemic in 2020. The study illustrates how social inequalities engenders heterogeneity in the psychosocial risk of older adults before and during the pandemic. These findings should stimulate more nuanced and equity-oriented depictions, research and policies about loneliness among older adults in the peri-pandemic era.

Acceptability and Feasibility of an Intervention to Enhance Social Group Belonging: Evidence From Three Trials of Groups 4 Health

Groups 4 Health (G4H) is a group psychotherapy program that targets social group disconnection. An emerging evidence base supports its efficacy in reducing loneliness, depression, and social anxiety. However, to date there has been no formal analysis of its acceptability to clients and therapists, nor an investigation of its feasibility for wider implementation. This input from end users is crucial to ensure the program's wider suitability and to contribute to its improvement. This study drew data from three clinical trials, including 266 G4H clients and 68 G4H therapists. From the Phase III trial only, additional data were available from 90 clients in a dose-controlled cognitive-behavioral therapy (CBT) comparison group, and focus groups/interviews with 6 therapists and 13 clients. Client satisfaction was high, with all average ratings >7/10, significantly exceeding the CBT comparison group. Therapist satisfaction with each module was >5/7. Retention was >80%. Homework completion was high, with <10% of clients saying that they had not attempted the homework. Therapists and clients both emphasized the benefits arising from G4H, and the contribution of the group context itself as a vehicle to achieve positive outcomes.

Has Smartphone Use Influenced Loneliness during the COVID-19 Pandemic in Japan?

The influence of smartphone use on increased risk of feeling lonely has been recognized as a global public health concern. However, it is unclear whether this influence has changed during the ongoing COVID-19 pandemic, during which smartphones have become a particularly important means of communication due to health safety measures restricting personal interactions. We used Hiroshima University's online survey data collected from 18-28 February 2022, to assess the impact of smartphone use on loneliness in Japan. The final sample included 2630 participants aged over 20 years, with loneliness measured using the UCLA scale and smartphone use calculated as the duration of usage in minutes/day. Weighted logit regression analysis was used to examine the association between smartphone use and loneliness, with other demographic, socioeconomic, and psychological characteristics as explanatory variables. Contrary to conventional evidence, our findings show that smartphone use mitigated the risk of loneliness during the pandemic. This was especially true among females under 65 years old. We found that age, subjective health status, future anxiety, and depression impacted this relationship. The findings of this study can help guide policymaking by showing the importance of providing adequate digital platforms to manage loneliness and mental health during times of isolation.

Job stress and loneliness among desk workers during the COVID-19 pandemic in Japan: focus on remote working

Background

Previous studies have reported an increase in loneliness since the outbreak of coronavirus disease 2019 (COVID-19), but there are few data on the relationship between job stress and loneliness. This study aimed to assess the relationship between job stress and loneliness among desk workers, with a focus on the impact of remote working.

Methods

This study was part of the Collaborative Online Research on the Novel-coronavirus and Work (CORoNaWork) project in Japan. We extracted data from 13,468 workers who indicated that they were doing desk work. Loneliness was assessed using a single question and job stress was valuated using the Job Content Questionnaire (JCQ). Multiple logistic regression was performed.

Results

Participants who worked remotely 4 or more days per week were marginally more likely to report feeling lonely compared with those who did not work remotely (adjusted odds ratio = 1.23, 95% CI: 0.99–5.84, P = 0.066). Remote working did not explain the interaction between JCQ scale scores and loneliness. Among remote workers, the level of support provided by co-workers and supervisors was strongly associated with feelings of loneliness as well as non-remote workers (co-worker support: AOR = 4.06, 95% CI: 2.82–5.84, P < 0.001; supervisor support: AOR = 2.49, 95% CI: 1.79–3.47, P < 0.001).

Conclusions

To reduce loneliness and the risk of associated mental health problems, high-frequency remote workers should interact with supervisors and co-workers using the information and communication technology developed for this purpose.

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

Despite the substantial literature on how loneliness is associated with poor health and premature mortality, there is little detailed research on the extent of its economic gradients. We provide this evidence using a sample of around 400,000 respondents aged 40-70 years from the UK Biobank, who were assessed between 2006 and 2010. We focus on differences in loneliness, as well as social isolation and a lack of social support, across educational attainment, household income, local area deprivation, and recent experience of financial stress. We employ two statistical approaches, the first exploiting the large sample size and detailed geographical information about where respondents live, so we compare individuals who differ in their economic status but reside within the same postcode district. The second approach exploits the fact that for around 36,000 respondents we observe their social health and economic circumstances at two points in time (second wave of assessment conducted between 2014 and 2020), so we conduct a panel analysis that accounts for intercorrelations between the social health measures, and controls for incomplete follow-up of panel members. Across both approaches, we find a substantially higher probability of reporting loneliness, social isolation and a lack of social support, for men and women with lower economic status. Together with the existing health-loneliness literature, these findings establish a 'loneliness pathway' contributing to health inequalities, and consequently a need for effective interventions that might address loneliness and social isolation as part of a broad policy initiative on health inequalities.

Social attitudes and activities associated with loneliness: Findings from a New Zealand national survey of the adult population

There has been growing recognition of the harmful consequences of loneliness for health and well-being, and the need for community intervention, particularly in times of global crisis such as the Covid-19 pandemic with its imperatives of distancing, isolation, and quarantine. Social capital and a sense of social cohesion are known to have roles in buffering against the effects of adverse life circumstances. Our study sought to investigate the association of a range of social attitudes and activities - as proxies for social capital - with loneliness while taking into account socio-demographic factors. We undertook a national survey on a stratified random sample of the New Zealand (NZ) adult population aged 18+ in 2017 (n = 1,358), data from which included the requisite variables. The prevalence of loneliness was highest in young adults (18-30), falling with age until a slight rise in older people (76+). Loneliness was associated with socio-demographic factors, being more prevalent in the more disadvantaged groups: the deprived, Māori (the indigenous people of NZ), the non-partnered, and the less educated. Controlling for these socio-demographic factors, pro-social attitudes (that is towards political efficacy, trust in others, not feeling exploited, or being committed to family) and participation in social activities (that is being employed or being involved in recreation groups) - were protective against loneliness. Our study supports asset-based approaches to tackling loneliness - with implications for health and social care - that emphasise mobilising existing social resources, building social capital, and raising social cohesion in our communities. Such intervention on loneliness would help to prevent and ameliorate its detrimental consequences for public health.

Understanding the effect of loneliness on unemployment: propensity score matching

Background

Loneliness and unemployment are each detrimental to health and well-being. Recent evidence suggests a potential bidirectional relationship between loneliness and unemployment in working age individuals. As most existing research focuses on the outcomes of unemployment, this paper seeks to understand the impact of loneliness on unemployment, potential interaction with physical health, and assess bidirectionality in the working age population.

Methods

This study utilised data from waves 9 (2017–19) and 10 (2018–2020) of the Understanding Society UK Household Longitudinal Study. Nearest-neighbour probit propensity score matching with at least one match was used to infer causality by mimicking randomisation. Analysis was conducted in three steps: propensity score estimation; matching; and stratification. Propensity scores were estimated controlling for age, gender, ethnicity, education, marital status, household composition, number of own children in household and region. Findings were confirmed in panel data random effect models, and heterogeneous treatment effects assessed by the matching-smoothing method.

Results

Experience of loneliness in at least one wave increased the probability of being unemployed in wave 10 by 17.5 [95%CI: 14.8, 20.2] percentage points. Subgroup analysis revealed a greater effect from sustained than transitory loneliness. Further exploratory analysis identified a positive average treatment effect, of smaller magnitude, for unemployment on loneliness suggesting bidirectionality in the relationship. The impact of loneliness on unemployment was further exacerbated by interaction with physical health.

Conclusions

This is the first study to directly consider the potentially bidirectional relationship between loneliness and unemployment through analysis of longitudinal data from a representative sample of the working age population. Findings reinforce the need for greater recognition of wider societal impacts of loneliness. Given the persisting and potentially scarring effects of both loneliness and unemployment on health and the economy, prevention of both experiences is key. Decreased loneliness could mitigate unemployment, and employment abate loneliness, which may in turn relate positively to other factors including health and quality of life. Thus, particular attention should be paid to loneliness with additional support from employers and government to improve health and well-being.

Is Loneliness an Undervalued Pathway between Socio-Economic Disadvantage and Health?

Loneliness is a growing public health issue. It is more common in disadvantaged groups and has been associated with a range of poor health outcomes. Loneliness may also form an independent pathway between socio-economic disadvantage and poor health. Therefore, the aim of this study was to explore the contribution of loneliness to socio-economic health inequalities. These contributions were studied in a Dutch national sample (n = 445,748 adults (≥19 y.o.)) in Poisson and logistic regression models, controlling for age, gender, marital status, migration background, BMI, alcohol consumption, smoking, and physical activity. Loneliness explained 21% of socioeconomic health inequalities between the lowest and highest socio-economic groups in self-reported chronic disease prevalence, 27% in poorer self-rated health, and 51% in psychological distress. Subgroup analyses revealed that for young adults, loneliness had a larger contribution to socioeconomic gaps in self-rated health (37%) than in 80+-year-olds (16%). Our findings suggest that loneliness may be a social determinant of health, contributing to the socioeconomic health gap independently of well-documented factors such as lifestyles and demographics, in particular for young adults. Public health policies targeting socioeconomic health inequalities could benefit from integrating loneliness into their policies, especially for young adults.

Who is at Risk of Loneliness? A Cross-sectional Recursive Partitioning Approach in a Population-based Cohort of Persons With Spinal Cord Injury

OBJECTIVE

To develop a more thorough understanding of the risk factors for loneliness in persons with a physical impairment, using a population-based sample of persons with spinal cord injury (SCI), based on regression modeling and a recursive partitioning approach.

DESIGN

Cross-sectional, observational cohort.

SETTING

Community, Switzerland.

PARTICIPANTS

Community-dwelling persons with spinal cord injury (N=1283) 16 years or older.

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Loneliness was assessed using a modified version of the UCLA Three-Item Loneliness Scale.

RESULTS

Those with the most disadvantaged socioeconomic characteristics in terms of education, income, subjective social position, employment status, and financial hardship demonstrated the highest risk for loneliness. Of the sociodemographic characteristics, only age had an association with loneliness, whereby persons aged 31-45 had the highest propensity for experiencing loneliness. We also saw that those with higher lesion levels and less functional independence were associated with higher levels of loneliness. In conditional inference tree analysis subjective social position, financial hardship, and functional independence had the highest discriminative power, with nationality and living arrangement having a less important role.

CONCLUSIONS

Our findings highlight the vulnerability of persons with SCI with unfavorable socioeconomic status to loneliness. Furthermore, our findings show that persons who are more constrained because of functional limitations may face restrictions to social participation and therefore be at a higher risk of loneliness. This population-based evidence contributes to the better targeting of services aimed at alleviating loneliness for persons with a lower socioeconomic position and those with more functional limitations in everyday life.

Does unemployment lead to greater levels of loneliness? A systematic review

There is evidence that loneliness and unemployment each have a negative impact on public health. Both are experienced across the life course and are of increasing concern in light of the COVID-19 pandemic. This review seeks to examine the strength and direction of the relationship between loneliness and unemployment in working age individuals, and in particular the potential for a self-reinforcing cycle with combined healthcare outcomes. A systematic search was undertaken in Medline, PubMed, PsycINFO, Embase and EconLit from inception to December 2020. PRISMA reporting guidelines were followed throughout this review, study quality was assessed using the Joanna Briggs Institute checklist and results were summarised in a narrative synthesis. English language studies evaluating the relationship between loneliness and unemployment in higher income western countries were included. Thirty-seven studies were identified; 30 cross-sectional and 7 longitudinal. Loneliness was measured by a direct question or loneliness scale while unemployment was self-reported or retrieved from a national register. A positive association between unemployment and increased loneliness was observed across all studies. Thus, across the life-course a clear yet complex relationship exists between unemployment and greater experience of loneliness. The magnitude of this relationship increases with the severity of loneliness and appears to peak at age 30–34 and 50–59. Logistic regression provided the greatest consistency at statistical significance revealing at least a 40% increase in the likelihood of reporting loneliness when unemployed. Recent longitudinal studies identified in this review found higher levels of loneliness following job loss, but also that loneliness was predictive of unemployment suggesting potential bi-directionality in the relationship. This bi-directionality may create a multiplier effect between loneliness and unemployment to form a self-reinforcing relationship and greater health concerns for those most at risk. Thus, review findings suggest the need for cross-sector awareness and intervention to tackle both loneliness and unemployment.

•

Unemployment is related to feeling lonely.

•

Stronger association of unemployment with severe experience of loneliness.

•

Greatest connection between loneliness and unemployment at age 30–34 and 50-59.

•

Potential for a bi-directional relationship between loneliness and unemployment.

•

Greater understanding is needed in the face of COVID-19 recovery.

Association Between Time Spent With Family and Loneliness Among Japanese Workers During the COVID-19 Pandemic: A Cross-Sectional Study

Background: The current coronavirus (COVID-19) pandemic has had large impacts on society, including people practicing social distancing. This behavioral response has increased loneliness. Loneliness not only increases the risk of psychiatric disorders, but also affects occupational mental health. To avoid the negative effects of isolation, it is important to have social contact with other people, especially family members. Employment and economic instability caused by COVID-19 may have also affected family relationships. It is important to understand the association between family relationships and loneliness in workers under the pandemic. Methods: We collected usable data from 27,036 Japanese workers who completed an online survey during the COVID-19 pandemic. Participants were asked how long they spend with members of their family during mealtimes or at home, and if they experienced loneliness; the latter was assessed by a single question. Other questions included whether participants lived with their spouse, or with someone in need of care. To estimate the odds ratios (ORs) of time with family associated with loneliness we used a multilevel logistic model nested in the prefecture of residence, with adjustments for age, sex, marital status, presence of a cohabitant requiring care, equivalent income, educational level, number of employees in the workplace, frequency of remote work, availability of someone for casual chat, smoking, drinking, time for leisure interests, and cumulative rates of COVID-19 in the prefecture. Results: Ten percent (2,750) of the 27,036 participants reported loneliness. The survey showed a significant negative correlation between time spent with family and loneliness (p < '0.001): participants who spent more time with family were less likely to feel loneliness. In addition, not living with a spouse and living with someone in need of care were associated with loneliness (not living with a spouse: p < 0.001; living with someone in need of care: p < 0.001). Conclusion: Loneliness under COVID-19 pandemic conditions was negatively associated with time spent with family members, with the converse result found for participants cohabiting with someone in need of care. These associations suggest the potential value of changes to working practices and interventions to combat loneliness.

[Unwanted loneliness, health and social inequalities throughout the life cycle]

OBJECTIVE

To analyse the prevalence of unwanted loneliness in our context and its association with health from a life cycle and social inequalities perspective.

METHOD

Cross-sectional study based on data from the Health Survey of the Basque Country (n = 7.228; response rate 79%). The prevalence of unwanted loneliness, its association with perceived health and mental health, and social inequalities according to social class were analysed. To analyse the association, age-adjusted prevalence ratios (PR) calculated from robust Poisson models were calculated.

RESULTS

The feeling of unwanted loneliness affects 23.3% of men and 29.7% of women, being higher in older people and young adults, and in the most disadvantaged social classes. Feeling alone is associated with worse health, both general (PRa men 2.11, 95% confidence interval [95%CI] 1.77-2.51; PRa women 2.10, 95%CI 1.83-2.41) and mental (PRa men 3.95, 95%CI 3.15-4.95; RPa women 3.50, 95%CI 2.99-4.12). Social inequalities in loneliness, as well as the association between it and poor health, was greater among young adults.

CONCLUSIONS

The results of the study have important implications for intervention in the reduction and prevention of unwanted loneliness, underlining the importance of the life cycle and social inequalities.

Risk factors for loneliness: The high relative importance of age versus other factors

Loneliness is a potent predictor of negative health outcomes, making it important to identify risk factors for loneliness. Though extant studies have identified characteristics associated with loneliness, less is known about the cumulative and relative importance of these factors, and how their interaction may impact loneliness. Here, 4,885 individuals ages 10-97 years from the US completed the three-item UCLA Loneliness Survey on TestMyBrain.org. Using census data, we calculated the population and community household income of participants' census area, and the proportion of individuals in the participant's census area that shared the participant's demographic characteristics (i.e., sociodemographic density). We evaluated the relative importance of three classes of variables for loneliness risk: those related to the person (e.g., age), place (e.g., community household income), and the interaction of person X place (sociodemographic density). We find that loneliness is highly prevalent and best explained by person (age) and place (community household income) characteristics. Of the variance in loneliness accounted for, the overwhelming majority was explained by age with loneliness peaking at 19 years and declining thereafter. The congruence between one's sociodemographic characteristics and that of one's neighborhood had no impact on loneliness. These data may have important implications for public health interventions.

The Stability and Change of Loneliness Across the Life Span: A Meta-Analysis of Longitudinal Studies

Individuals experience loneliness when they perceive a deficiency in the quality or quantity of their social relationships. In the present meta-analysis, we compiled data from 75 longitudinal studies conducted in Asia, Australia, Europe, and North America (N = 83, 679) to examine the rank-order and mean-level development of loneliness across the life span. Data were analyzed using two- and three-level meta-analyses and generalized additive mixed models. The results indicate that the rank order of loneliness is as stable as the rank order of personality traits and follows an inverted U-shaped trajectory across the life span. Regarding mean-level development, loneliness was found to decrease throughout childhood and to remain essentially stable from adolescence to oldest old age. Thus, in contrast to other personality characteristics, changes in loneliness are not generally related to age. Implications for theory are discussed.

Friendships that money can buy: financial security protects health in retirement by enabling social connectedness

Background

Research on the health and wellbeing of retirees has tended to focus on financial security and financial planning. However, we suggest that one reason why financial security is important for retirees is that it enables social connectedness, which is critical for healthy ageing.

Methods

This paper tests this hypothesis cross-sectionally (N = 3109) and longitudinally (N = 404) using a population-weighted mixed effects mediation model in two nationally representative samples of Australian retirees.

Results

Analyses provide robust support for our model. Subjective financial security predicted retiree health cross-sectionally and longitudinally. Social connectedness also consistently predicted mental health and physical health, on average four times more strongly than financial security. Furthermore, social connectedness partially accounted for the protective effect of subjective financial security.

Conclusions

We discuss the implications of these findings for public health, with a particular emphasis on how social connectedness can be better supported for people transitioning to retirement.

Defining loneliness in older adults: protocol for a systematic review

BACKGROUND

Socialization is an important part of the healthy aging process, but natural changes in the lifestyle and health of older people increased risk of loneliness. However, loneliness is not well defined and might differ in different cultures and settings. The main objective of this systematic review is to summarize literature on the topic and propose a definition that might help aging research and practice in the future.

METHODS

Eight databases including PubMed, Scopus, CINAHL, Web of Science, EMBASE, PsycINFO, Proquest, and Age Line bibliographic will be run individually to retrieve relevant literature on loneliness among elderly population using subject headings and appropriate MeSH terms. Inclusion and exclusion criteria will be developed and refined by the research team. Two reviewers will participate in each search stage including abstract/title and full text screening, data extraction, and appraisal. We will restrict our search to articles published in the English language biomedical journal between 2000 and 2017. The protocol adheres to the standards recommended by the PRISMA-P.

DISCUSSION

The results of this systematic review can present a more accurate definition of loneliness for researchers who aim at conducting new primary and secondary studies on this subject.

With whom are you dealing? Using social network analysis as a tool to strengthen service delivery structures for low socioeconomic status populations

Background: Health disparities between populations with different socioeconomic status (SES) are increasing. Although a wide variety of support service organizations and arrangements are in place, no general overview of this social network, its reach, and harmonization of services surrounding low-SES populations are available. The present participatory health research study examined the current network structure and the utility of using social network analysis (SNA) as a tool to improve service delivery structures. Design and methods: We applied a mixed-methods study design. An online-questionnaire was used to examine the relationships among organizations assumed to support low-SES individuals in the municipality of Vaals, the Netherlands. In addition, semi-structured interviews and a networking session were used to examine the current network structure and to explore opportunities for improvement. Results: The SNA revealed a weak network structure, and all interviewed professionals mentioned that the current structure should be improved. Participants indicated that a first step would be to install a central information system. Conclusions: SNA can be a useful tool to gain more in-depth insights into the relations within a service delivery network. The professionals were assisted in discovering new organizations that could help them reach low SES populations and in harmonizing and improving their service delivery.

The relationship between wealth and loneliness among older people across Europe: Is social participation protective?

OBJECTIVE

1. Examine the relationship between household wealth, social participation and loneliness among older people across Europe. 2. Investigate whether relationships vary by type of social participation (charity/volunteer work, sports/social clubs, educational/training course, and political/community organisations) and gender. 3. Examine whether social participation moderates the association between wealth and loneliness.

METHODS

Data (N=29,795) were taken from the fifth wave of the Survey of Health, Ageing and Retirement in Europe (SHARE), which was collected during 2013 from 14 European countries. Loneliness was measured using the short version of the Revised-University of California, Los Angeles (R-UCLA) Loneliness Scale. We used multilevel logistic models stratified by gender to examine the relationships between variables, with individuals nested within countries.

RESULTS

The risk of loneliness was highest in the least wealthy groups and lowest in the wealthiest groups. Frequent social participation was associated with a lower risk of loneliness and moderated the association between household wealth and loneliness, particularly among men. Compared to the wealthiest men who often took part in formal social activities, the least wealthy men who did not participate had greater risk of loneliness (OR=1.91, 95% CI: 1.44 to 2.51). This increased risk was not observed among the least wealthy men who reported frequent participation in formal social activities (OR=1.12, 95% CI: 0.76 to 1.67).

CONCLUSION

Participation in external social activities may help to reduce loneliness among older adults and potentially acts as a buffer against the adverse effects of socioeconomic disadvantage.

The burden of chronic noncommunicable diseases in undocumented migrants: a 1-year survey of drugs dispensation by a non-governmental organization in Italy

OBJECTIVES

This study was carried out with two objectives. The first one was to have an insight into the prevalence of chronic noncommunicable diseases (CNCD) in undocumented migrants, and the second one was to evaluate if differences existed among different ethnic groups.

STUDY DESIGN

The study is based on the collection of data on drug dispensation by a non-governmental organization (NGO) providing free medical assistance to undocumented migrants in Milan, Italy. All the prescriptions to adult subjects from January 1 to December 31 2014 (total 8438) were recorded and analyzed. All the data available for the patients receiving prescriptions (age, gender and country of birth) were also collected in anonymous form. Ethical approval for the study was given by the Ethics Committee of the NGO.

METHODS

Drugs were grouped according to the anatomical therapeutic chemical (ATC) classification and their quantities expressed as daily defined doses (DDDs)/1000 patients/day. The 56 ATC levels were divided into three groups according to their use for acute, chronic, or both acute and chronic diseases. The statistical analysis of drug dispensation was performed for the whole population and for the five ethnic groups into which it had been divided.

RESULTS

Prescription of medicines for chronic conditions was significantly greater than for acute (154.2 ± 45.9 vs 51.3 ± 18.4 DDD/1000 patients/day, P < 0.02) and for both acute and chronic conditions (57.9 ± 12.8 DDD/1000 patients/day, P < 0.02). Five ATC classes accounted for 60% of all chronic prescriptions. They were differently distributed among the five ethnic groups (e.g., Asians required more antihypertensives and antidiabetics, East Europeans required more lipid modifying drugs, antihypertensives and antithrombotics).

CONCLUSIONS

Our data show an important use of medicines for chronic diseases in a population of undocumented migrants. Though with some limitations, this could be an indicator of a high prevalence of CNCD in this population, with significant differences among different ethnic groups. This situation should be considered when planning health interventions, also in consideration of the fact that it could have an impact on European Health Services in a short time.

Age differences in loneliness from late adolescence to oldest old age

Contrary to common stereotypes, loneliness is not restricted to old age but can occur at any life stage. In this study, we used data from a large, nationally representative German study (N = 16,132) to describe and explain age differences in loneliness from late adolescence to oldest old age. The age distribution of loneliness followed a complex nonlinear trajectory, with elevated loneliness levels among young adults and among the oldest old. The late-life increase in loneliness could be explained by lower income levels, higher prevalence of functional limitations, and higher proportion of singles in this age group. Consistent with an age-normative perspective, the association of income, relationship status, household size, and work status with loneliness differed between different age groups. In contrast, indicators of the quantity of social relationships (social engagement, number of friends, contact frequency) were universally associated with loneliness regardless of age. Overall, these findings show that sources of loneliness in older adults are well understood. Future research should focus on understanding the specific sources of loneliness in middle-aged adults.
