Does life satisfaction predict five-year mortality in community-living older adults?

Life satisfaction components and all-cause and cause-specific mortality: A large prospective cohort study

BACKGROUND

Which life satisfaction components could be a target of positive psychological interventions for longevity is largely unknown. We aimed to investigate association of the composite measure of life satisfaction and its individual components with mortality.

METHODS

This cohort study included UK Biobank participants who responded to questions concerning five components of life satisfaction at baseline. We generated a composite score representing overall life satisfaction, ranging from 0 (lowest) to 5 (highest). The outcomes were all-cause and cause-specific mortality. We used multivariable Cox regression to estimate hazard ratios (HR) for the associations of interest.

RESULTS

Among 165,842 eligible participants, 12,261 all-cause deaths were observed over a median of 12.9-year follow-up. Overall life satisfaction was inversely associated with all-cause mortality (adjusted HR 0.94 [95% CI: 0.93-0.95] per 1 score increment). Health satisfaction showed the strongest association with all-cause mortality, with a fully adjusted HR of 0.52 (95% CI: 0.49-0.55) for high/extreme satisfaction and 0.63 (95% CI: 0.59-0.66) for moderate satisfaction, compared with unsatisfaction (P-trend<0.001), independent of other satisfaction components, regardless of physical health and sociodemographics. The association for family, friendship, work and financial satisfaction was attenuated when adjusted for other life satisfaction components. Similar findings were observed for cause-specific mortality.

LIMITATIONS

Observational study with single baseline measurement of life satisfaction precludes the ability to establish causal relationship.

CONCLUSIONS

Higher overall life satisfaction was associated with lower mortality. As the major contributor to lower mortality regardless of physical health and sociodemographics, health satisfaction could be an important target of positive psychological interventions for longevity.

Review of the effect cultural capital and subjective socioeconomic status on life satisfaction in Iran: the mediating role of health-promoting lifestyle and the moderating role of ethnicity

INTRODUCTION

Health-promoting lifestyle can leads to improving the quality of life, life satisfaction, well-being and reducing the burden of health care in the society. This study was carried out to investigate the mediating role of health-promoting lifestyle and moderating role of ethnicity in the effect of cultural capital and subjective socioeconomic status on life satisfaction in Iran.

METHODS

This cross-sectional study was conducted with 800 respondents in the cities of Kermanshah with Kurdish ethnicity and Tabriz with Azeri ethnicity. The data gathering tool was a questionnaire in five section including demographic checklist, cultural capital questionnaire (2015),Diener's life satisfaction scale, and health-promoting lifestyle questionnaire (HPLP II), and socioeconomic status scale. Data were analyzed by SPSS and AMOS software.

RESULTS

Life satisfaction had the highest correlation with the objective dimension of cultural capital (p < 0.001 r = 0.298). The direct standardized coefficient of the path of cultural capital to health-promoting lifestyle was 0.44 (P < 0.001). Also the direct standardized coefficient of cultural capital on Life satisfaction was 0.04 that was not significant. The standard coefficient of the path of cultural capital on life satisfaction through health-promoting lifestyle was 0.27(P < 0.001). Ethnicity variable did not moderate the effect of cultural capital on life satisfaction (p > 0.05).

CONCLUSION

The results of this study showed that paying attention to the concept of health-promoting lifestyle is a necessity to affect life satisfaction. It can play a role as a mediator for the path of cultural capital and socio-economic status on life satisfaction. This study also showed the role of ethnicity as a moderating variable in the relationship between socio-economic status and health-promoting lifestyle.

Community-based service, psychological resilience and life satisfaction among Chinese older adults: A longitudinal study

Previous research has suggested that community-based service is beneficial in promoting older adults' life satisfaction. However, there is limited knowledge of the mediating mechanisms that foster this relationship. Thus, the current study aims to explore the mediating role of psychological resilience in the association between community-based service and life satisfaction among older adults. Using data collected over four rounds of the Chinese Longitudinal Healthy Longevity Survey (CLHLS), this study analyzes the responses of 1439 older adults in China. The results reveal that community-based service is positively related to life satisfaction among older adults. Furthermore, psychological resilience partially mediates this association, highlighting its potential role in promoting life satisfaction. These findings contribute to a deeper theoretical understanding of the mechanisms underlying the relationship between community-based service and older adults' life satisfaction while offering practical implications for enhancing the life satisfaction of older adults in China.

The Moderating Effect of Personal Assets in the Relationships between Subjective Health, Housing Expense, and Life Satisfaction for Korean Middle and Old-Aged

The proportion of the elderly in Korea has increased. Given the circumstances, this research is intended to explore the characteristics of the elderly. The aim of this research is to explore the antecedents of life satisfaction in the Korean elderly using subjective health. Next, the goal of this research is to appraise the moderating effect of personal assets in the relationship between life satisfaction and housing expenses. The study data consist of 7199 observations from the 2018 and 2020 waves of the Korean Longitudinal Study of Aging (KLOSA). This research uses econometric analysis to test the research hypotheses, which include ordinary least squares, fixed-effects, and random-effects regression analyses. Following ordinary least squares, fixed-effects, and random-effects regression analyses, the results indicate a positive influence of subjective health on older Koreans' life satisfaction. Additionally, personal assets positively moderate the association between housing expense and life satisfaction, the most valuable finding of the study. This research sheds light on the literature by revealing the moderating effect on the relationship between housing expense and life satisfaction. Moreover, the results could be used for better policy design with respect to the middle- and old-aged members Korean society.

Cognitive Function and Depressive Symptoms among Chinese Adults Aged 40 Years and Above: The Mediating Roles of IADL Disability and Life Satisfaction

The purpose of this study was to investigate the relationship between cognitive function and depressive symptoms among Chinese adults aged 40 years and above, as well as the series of multiple mediating effects of Instrument Activities of Daily Living disability and life satisfaction on this relationship. The data was obtained from the China Health and Retirement Longitudinal Study (CHARLS, 2013-2018), including 6466 adults aged 40 years and above. The mean age of the adults was 57.7 ± 8.5. The SPSS PROCESS macro program was conducted to examine the mediating effects. The results indicated that there was a significant association between cognitive function and depressive symptoms five years later (B = -0.1500, 95%CI: -0.1839, -0.1161), which could also be demonstrated through three mediation pathways: (1) the mediating pathway through IADL disability (B = -0.0247, 95%CI: -0.0332, -0.0171); (2) the mediating pathway through life satisfaction (B = 0.0046, 95%CI: 0.0000, 0.0094); and (3) the chain mediation pathway through IADL disability and life satisfaction (B = -0.0012, 95%CI: -0.0020, -0.0003). Both IADL disability and life satisfaction have been proven to be crucial mediators for the relationship between cognitive function and depressive symptoms five years later. It is necessary to improve individuals' cognitive function and reduce the negative impact of disability on them, which is important to enhance their life satisfaction and prevent depressive symptoms.

The role of marriage in the life satisfaction and mortality association at older ages: age and sex differences

OBJECTIVES

Although life satisfaction (LS) could reduce mortality risk of older adults, whether the LS-mortality link is consistent in older adults with different marital status is largely unknown. In this study, we examine (1) how the LS-mortality association at older ages varies by marital status and marital quality, and (2) whether the role of marriage in the LS-mortality link differs between young-old (ages 65-79) and oldest-old (ages 80+) ages and between men and women in mainland China.

METHODS

We used five waves of data from a nationally representative survey in mainland China and applied the multilevel random effect of survival analysis to examine the LS-mortality association in Chinese older adults by marital status, controlling for a wide set of covariates.

RESULTS

First, the protective effect of LS on mortality was valid in older men regardless of their marital status, whereas the protective effect was only valid in currently-not-married older women. Second, for a good marriage, LS significantly reduced mortality risk irrespective of gender and age, while for a poor marriage, LS had no significant association with mortality of older adults. Third, the LS-mortality association seemed to be stronger in the oldest-old than in the young-old irrespective of their marital status.

CONCLUSION

Given the pivotal role of spouse in daily life, the society should create an age-friendly social environment for re-marriage among older adults who wish to get re-married, while highlighting and advocating the importance of good marriage in determining healthy aging, and design various policies to improve the LS of older people to reduce their mortality risk.

Life Satisfaction and Intergenerational Mobility Among Older Hispanics in the United States

OBJECTIVES

To investigate the impact of intergenerational mobility-measured as the difference between one's own and one's father's education level-on overall life-satisfaction among Hispanic, White, and Black older Americans.

METHODS

Data from the Health and Retirement Study were used to estimate life satisfaction by race/ethnicity using ordinary least squares regression (N = 5,057).

RESULTS

Hispanic and Black older Americans report greater educational gains relative to their fathers compared to Whites. Despite having the lowest reported education levels, Hispanics report the highest life satisfaction across race/ethnic groups. However, net of education level and other factors, intergenerational mobility decreased rather than increased life satisfaction for Hispanic older Americans.

DISCUSSION

These results indicate that intergenerational mobility may not confer equal benefits for overall life satisfaction across racial/ethnic groups. As Hispanic individuals continue to achieve higher education levels, it is unclear whether upward mobility will translate to positive or negative assimilation consequences.

Homeownership, Depression, and Life Satisfaction in China: The Gender and Urban-Rural Disparities

This study examines how depression and life satisfaction are associated with assets in the form of homeownership in China and whether their relationships differ between men and women, and between urban and rural areas. While the psychological benefits of homeownership are well-documented, how gender makes a difference in this relationship remains unclear. Given the dynamic housing market conditions characterized by the urban-rural divide and the notable gender gap in psychological well-being, China can provide a relevant context to address this knowledge gap. A series of linear regression analyses based on the China Family Panel Studies (CFPS) data show that homeownership is positively associated with life satisfaction and negatively related to depression, and this relationship is driven by men. While the homeownership-life satisfaction relation does not differ between urban and rural areas, the negative association between homeownership and depression is seen only among rural residents. The gender difference could be explained by the salient role of the financial security obtained from homeownership, whereas the regional difference seems to be supported by the social comparison theory. This study contributes to the knowledge of how a biological determinant, i.e., gender, interacts with a social determinant, i.e., homeownership, to affect psychological well-being.

The double-edged role of accessed status on health and well-being among middle- and older-age adults in rural South Africa: The HAALSI study

Background

Social capital theory conceptualizes accessed status (the socioeconomic status of social contacts) as interpersonal resources that generate positive health returns, while social cost theory suggests that accessed status can harm health due to the sociopsychological costs of generating and maintaining these relationships. Evidence for both hypotheses has been observed in higher-income countries, but not in more resource-constrained settings.

We therefore investigated whether the dual functions of accessed status on health may be patterned by its interaction with network structure and functions among an older population in rural South Africa.

Method

We used baseline survey data from the HAALSI study (“Health and Aging in Africa: a Longitudinal Study of an INDEPTH Community in South Africa”) among 4,379 adults aged 40 and older. We examined the direct effect of accessed status (measured as network members’ literacy), as well as its interaction with network size and instrumental support, on life satisfaction and self-rated health.

Results

In models without interactions, accessed status was positively associated with life satisfaction but not self-rated health. Higher accessed status was positively associated with both outcomes for those with fewer personal contacts. Interaction effects were further patterned by gender, being most health-protective for women with a smaller network and most health-damaging for men with a larger network.

Conclusions

Supporting social capital theory, we find that having higher accessed status is associated with better health and well-being for older adults in a setting with limited formal support resources. However, the explanatory power of both theories appears to depending on other key factors, such as gender and network size, highlighting the importance of contextualizing theories in practice.

•

We investigated the double-edged role of accessed status on self-rated health and life satisfaction among older South Africans in a rural setting.

•

Accessed status was overall positively associated with life satisfaction.

•

Accessed status was positively associated with health and well-being for women, unemployed respondents, and people with fewer social contacts.

•

We found an inverse association between accessed status and life satisfaction among men with a larger personal network.

The Roles of Life Satisfaction and Community Recreational Facilities in the Relationship between Loneliness and Depression in Older Adults

OBJECTIVES

This study examined the mediating effect of life satisfaction and the moderating effect of the availability of community recreational facilities (CRF) in the association between loneliness and depression in rural older adults and urban older adults, respectively.

METHODS

Quantitative data collected from 7547 Chinese older adults were analyzed using the SPSS macro PROCESS to test a moderated mediation model with life satisfaction as the mediator and CRF availability and residency type (rural vs. urban) as moderators.

RESULTS

Loneliness negatively predicted life satisfaction, life satisfaction negatively predicted depression, and loneliness positively predicted depression. The interaction of loneliness and CRF availability had a significant effect on depression for urban older adults but not for rural older adults. The direct impact of loneliness on depression differed significantly between rural and urban older adults.

CONCLUSIONS

Life satisfaction mediated the association between loneliness and depression in both rural and urban older adults; CRF availability unexpectedly boosted the effect of loneliness on depression in urban older adults but not in rural older adults. Given the same level of loneliness, urban older adults were more likely to be depressed than rural older adults.

CLINICAL IMPLICATIONS

Psychogeriatric practitioners may embed life satisfaction into intervention programs to minimize depression among older adults. Public administrators should examine the utilization of public facilities to avoid wasted resources and counterproductive effects on older adults. Lonely urban older adults deserve special attention.

The Role of Optimism on the Relationship Between Activity Limitations and Life Satisfaction Among Middle-Aged and Older Adults in the United States: A Growth Curve Model of Changes Over Time

Activity limitations can diminish life satisfaction. This study explored the role of optimism on the relationship between changes in activities of daily living and instrumental activities of daily living (ADL/IADL) limitations and life satisfaction over time among middle-aged and older adults. Growth curve modeling accounting for intra- and inter-individual changes in life satisfaction was applied to the 2008-2018 waves of the Health and Retirement Study Leave Behind Survey subsample (n = 39,122 person-years). After controlling for sociodemographic factors, physical functioning decline adversely affected life satisfaction (β_ADL = -0.12, β_IADL = -0.13, p < 0.001), but the negative consequences reduced slightly through optimism (β_ADL = -0.11, β_IADL = -0.12, β_optimism = 0.47, p < 0.001). Increasing optimism could reduce the negative consequences of ADL/IADL limitations on life satisfaction among middle-aged to older adults.

Does the psychological variables predict life satisfaction and purpose in life in brazilian elderly?

Aims: the present study aimed to investigate the association between indicatives of stress, anxiety and depression with life satisfaction and purpose in life among Brazilian older adults.Methods: this cross-sectional study was conducted with 654 Brazilian older adults who responded the Life Satisfaction Scale, Purpose in Life Scale, Perceived Stress Scale, Geriatric Anxiety Inventory and the Geriatric Depression Scale. Data were analyzed through independent t-test, Cohen’s D, Pearson Correlations and Multivariate Regression Analysis (p<0.05).Results: results indicated slightly higher levels of stress and anxiety for women when compared to men (p<0.05); indicatives of stress, anxiety and depression were inversely correlated to life satisfaction and purpose (r = -0.19 to -0.44; p<0.05); stress (β=-0.29) and depression (β=-0.36) were significant predictors of life satisfaction (R2=0.31; p<0.01), and life purpose (R2=0.18; p<0.01) was predicted by stress (β=-0.15), anxiety (β=0.10) and depression (β=-0.39).Conclusion: It can be concluded that stress and depression are significant factors hindering older adults’ satisfaction and purpose in life.

Life Satisfaction and the Relationship between Mild Cognitive Impairment and Disability Incidence: An Observational Prospective Cohort Study

The relationship between the incidence of disability and cognitive function has been clarified, but whether life satisfaction is related to this relationship is unclear. Therefore, the purpose of this study was to clarify whether life satisfaction is related to the relationship between the incidence of disability and mild cognitive impairment. We included 2563 older adults from the National Center for Geriatrics and Gerontology–Study of Geriatric Syndromes. Baseline measurements included cognitive, life satisfaction, and demographic characteristics. Life satisfaction was measured using the Life Satisfaction Scale, which was stratified into three levels based on the score: lower, moderate, and higher. Associations between disability incidence and mild cognitive impairment were examined for each group according to life satisfaction, and monthly assessment for disability was monitored through long-term care insurance certification for at least 2 years from the baseline. At a 35.5-month mean follow-up, 150 participants had developed a disability. The potential confounding factors adjusted hazard for incidence of disability in the group with lower life satisfaction was 1.88 (CI: 1.05–3.35; p = 0.034) for mild cognitive impairment. Mild cognitive impairment was associated with disability incidence, and the effect was more pronounced among older adults with lower life satisfaction.

Self-Rated Health and Subjective Economic Status in Life Satisfaction among Older Chinese Immigrants: A Cross-Sectional Study

This study examines the influence of self-rated health and subjective economic status on the life satisfaction of older Chinese immigrants in the United States. Data were obtained from a cross-sectional survey of 205 older Chinese immigrants aged 66 to 90 years living in Los Angeles and Honolulu. Ordinary Least Squares (OLS) regression analysis was employed to explore the independent effects of self-rated health and subjective economic status. The results demonstrated that self-rated health and subjective economic status were positively associated with life satisfaction. This cross-sectional study provides empirical evidence that self-rated health and subjective economic status are directly associated with subjective life satisfaction among older Chinese immigrants.

The predictive relationship between factors related to fear of falling and mortality among community-dwelling older adults in Korea: analysis of the Korean longitudinal study of aging from 2006 to 2014

OBJECTIVES

This study was conducted to identify the predictive relationship between factors related to fear of falling (FOF) and mortality among community-dwelling older adults in Korea.

METHOD

Data were obtained from the Korean Longitudinal Study of Aging (KLoSA). Hierarchical Cox proportional hazards regression analyses were conducted to identify factors related to FOF and correlations of these factors with mortality.

RESULTS

During the eight-year follow-up period, 964 participants (23.5%) died. Death was more likely to occur in males (hazard ratio [HR], 2.55; 95% confidence interval [95% CI], 2.17-3.00), those 75 years old or older (HR, 2.76; 95% CI, 2.40-3.17), those without education (HR, 1.27; 95% CI, 1.05-1.52), and those living without a spouse (HR, 1.30; 95% CI, 1.11-1.51). Those afraid of falling (HR, 1.41; 95% CI, 1.17-1.70), limiting their activities due to FOF (HR, 1.40; 95% CI, 1.21-1.62), showing symptoms of depression (HR, 1.34; 95% CI, 1.16-1.54), and having low life satisfaction (HR, 1.34; 95% CI, 1.13-1.59) were also more likely to experience decreased lifespans.

CONCLUSION

These results suggest that early management and prevention of factors related to FOF should be an effective approach to reducing mortality in older adults.

PROMIS® General Life Satisfaction scale: construct validity in musculoskeletal pain patients

BACKGROUND

Life satisfaction is part of subjective well-being. Measurement of life satisfaction is undertaken using self-report measures. This study aimed to evaluate the structural validity, concurrent validity, and internal structure of the PROMIS® General Life Satisfaction Scale (GLSS) in a musculoskeletal pain cohort.

METHOD

Consecutive new patients attending the Victoria University Osteopathy Clinic (Melbourne, Australia) were invited to complete the GLSS prior to their initial consultation. Structural validity and internal structure were explored using confirmatory factor analysis and Mokken scale analysis. Concurrent validity was evaluated against a single-item measure of life satisfaction.

RESULTS

The PROMIS® GLSS comprised a single factor and formed an acceptable Mokken scale in this population. No differential item functioning was observed. A large positive correlation (r = 0.70) was observed between the General Life Satisfaction scale and a single-item measure of life satisfaction.

CONCLUSIONS

The PROMIS® General Life Satisfaction scale demonstrated acceptable internal structure and structural validity in a musculoskeletal pain population. Additional research is required to explore concurrent validity and other measurement properties, however initial data suggests the measure could be a feasible screen of life satisfaction for Australian osteopathic patients.

Perceived Health and Life Satisfaction of Elderly People: Testing the Moderating Effects of Social Support, Attitudes Toward Aging, and Senior Privilege

As health declines with age, it is critical to explore moderators that could buffer the impact of declining health on life satisfaction of elderly people. This study aims to test the moderating effects of social support, attitudes toward aging, and senior privilege on the relationship between perceived health and life satisfaction among elderly people. The study used a sample of 5809 Chinese elderly people. Multiple regression analyses were performed to test the moderating effects of the study variables along with gender difference. The results show that social support and attitudes toward aging do not moderate the relationship between perceived health and life satisfaction; senior privilege however, amplifies the impact of perceived health on life satisfaction for female elderly people. The findings recommend personalized provision of senior privilege based on health status and types of diseases, rather than only based on age; and suggest tailored female-oriented social services such as psychological counseling and humanistic care.

Life satisfaction and musculoskeletal complaints in a population seeking osteopathy care: consecutive sample of 611 patients

Background

Life satisfaction is a component of the subjective well-being construct. Research consistently suggests that life satisfaction is associated with enhanced social benefits and improved health outcomes. However, its relationship to musculoskeletal health outcomes is underexplored. This study evaluates the life satisfaction of a patient population presenting with musculoskeletal complaints, and the relationship of life satisfaction with other health demographics and behaviours.

Method

The study used a consecutive sampling design. Patients attending the Victoria University Osteopathy Clinic (Melbourne, Australia) were invited to complete the PROMIS® General Life Satisfaction scale (GLSS) along with questions related to health demographics and behaviours.

Results

The GLSS T-score was not significantly different for gender, being born outside of Australia, speaking English at home, or complaint chronicity.

Conclusions

Life satisfaction did not appear to be related to a range of health and demographic variables in the current musculoskeletal pain cohort. The PROMIS® General Life Satisfaction scale could prove useful to explore the relationship between life satisfaction and treatment outcomes for musculoskeletal complaints.

Dissatisfaction with life and associated factors in older community-dwelling adults

Abstract Objective: To analyze the prevalence of dissatisfaction with life and associated sociodemographic factors. Method: A cross-sectional, population-based study was carried out. Data collection was performed using the Brazil Old Age Schedule (BOAS) questionnaire. A total of 573 older adults from the urban area were interviewed, selected through cluster sampling, stratified by sex. Bivariate analysis was performed using the chi-square and prevalence ratio with a 95% confidence interval (CI). For multivariate analysis, the Poisson Robust regression model was applied. Variables were entered into the model using the backward method. Results: The prevalence of dissatisfaction with life was 15.53%. Dissatisfaction with life was associated with women (PR=1.54; 95% CI: 1.02; 2.32), being illiterate (PR=2.57; 95% CI: 1.44; 4.60), having up to four years of schooling (PR=1.79; 95% CI: 1.01; 318) and having an income of less than two minimum wages (PR=3.29; 95% CI: 1.29; 8.42). In the multivariate analysis, being female (PR=1.50; 95% CI: 1.01; 2.25), being illiterate (PR=2.54; 95% CI: 1.42; 4.54) and having up to four years of schooling (PR=1.77; 95% CI: 0.99; 3.14) remained associated with dissatisfaction with life Conclusion: the prevalence of dissatisfaction is low. Dissatisfaction with life was associated with sex, education and income, in a bivariate manner. Sex and education were predictors of dissatisfaction with life. These findings reinforce the need for actions to promote social equality between men and women and to facilitate the access of older adults to education.

Lifestyle and psychosocial factors and a decline in competence in daily living among Japanese early elderly people: from an age-specified community-based cohort study (NISSIN project)

Background

To let the early elderly live well, understanding how lifestyle and psychosocial factors related to a decline in competence in daily living is important.

Methods

We investigated the associations between lifestyle and psychosocial factors at age 64 years and a decline in the Tokyo Metropolitan Institute of Gerontology Index of Competence score of ≥ 2 points at age 70 years among the participants in comprehensive medical check-ups living in a city in Japan. Multivariable logistic regression analyses were performed separately for men and women.

Results

Of the 1113 eligible men and 1203 eligible women, 110 men and 80 women showed a deteriorated competence in daily living during the 6 years. In men, risk was increased with ≥ 2 nighttime awakenings (multivariable odds ratio [mOR] 2.14, 95% confidence interval [CI] 1.19–3.86) and living alone (mOR 4.68, 95% CI 1.22–18.0), whereas risk was significantly decreased with a medium or fast gait (mOR 0.37 and 0.21, 95% CI 0.21–0.67 and 0.08–0.58) and high academic achievement (mOR 0.32 and 0.43, 95% CI 0.19–0.53 and 0.25–0.72). In women, risk was decreased with high life satisfaction (mOR 0.39, 95% CI 0.16–0.91) and participation in community activities (mOR 0.50, 95% CI 0.29–0.86) but increased with depressive mood (mOR 1.86, 95% CI 1.09–3.18).

Conclusion

Living alone for men and low life satisfaction for women at age 64 years were markedly associated with the risk of a subsequent declining competence in daily living.

Happiness and Health

Research into the relationship between happiness and health is developing rapidly, exploring the possibility that impaired happiness is not only a consequence of ill-health but also a potential contributor to disease risk. Happiness encompasses several constructs, including affective well-being (feelings of joy and pleasure), eudaimonic well-being (sense of meaning and purpose in life), and evaluative well-being (life satisfaction). Happiness is generally associated with reduced mortality in prospective observational studies, albeit with several discrepant results. Confounding and reverse causation are major concerns. Associations with morbidity and disease prognosis have also been identified for a limited range of health conditions. The mechanisms potentially linking happiness with health include lifestyle factors, such as physical activity and dietary choice, and biological processes, involving neuroendocrine, inflammatory, and metabolic pathways. Interventions have yet to demonstrate substantial, sustained improvements in subjective well-being or direct impact on physical health outcomes. Nevertheless, this field shows great potential, with the promise of establishing a favorable effect on population health.

Positive Mental Attitude Associated with Lower 35-Year Mortality: The Leisure World Cohort Study

Background

Although emerging research has suggested that "positive psychological well-being" is associated with better health outcomes, studies of long-term health and mortality in the elderly are limited. This study assessed the relationship of mental attitude and mortality in older adults followed up for 35 years.

Methods

In the 1980s, the Leisure World Cohort Study recruited residents of a California retirement community to a prospective cohort study of health promotion and disease prevention. Participants completed a postal survey including seven positively worded items from the Zung self-rating depression scale. Age-adjusted and multivariable-adjusted (for lifestyle behaviors and disease conditions) hazard ratios (HRs) for death were calculated using Cox regression for 8682 women and 4992 men (median age at entry, 74 years). During follow-up (1981-2016), 13,405 participants died (median age at death, 88 years).

Results

In both women and men, HRs for death were significantly related to mental attitude with increasing risk with decreasing positive responses for total attitude and the seven individual items. The multivariable-adjusted HR (95% CI) for death for individuals in the lowest vs. highest quarter of total attitude was 1.24 (1.16, 1.32) for women and 1.30 (1.19, 1.41) for men. Some attenuation in the observed associations occurred after adjustment for potential confounders and after elimination of the first five years of follow-up.

Conclusions

Our study suggests that persons with negative attitude have an increased risk of death even after many years of follow-up. Research into strategies to improve mental outlook may help improve the quantity as well as the quality of life.

Life Satisfaction and Hemodynamic Reactivity to Mental Stress

BACKGROUND

Satisfaction with life has been considered a health-protective variable, which could impact cardiovascular morbidity and mortality. However, few studies have examined the physiological pathways involved in the potentially salutary effect of life satisfaction. It was hypothesized that life satisfaction should be associated with a cardiovascular response profile that signals challenge (i.e., higher cardiac output, lower peripheral resistance), rather than threat during a mental stress task.

METHODS

A sample of 75 healthy, medication-free men without clinical signs of psychological disorders who worked full-time and occupied highly demanding positions participated in this study. They performed two mental stress tasks (n-back) with varying degrees of difficulty. The tasks were embedded between a baseline and a recovery period. Cardiovascular and hemodynamic variables (heart rate, blood pressure, cardiac output, total peripheral resistance) were recorded by means of impedance cardiography.

RESULTS

Individuals who were more satisfied with their life displayed higher cardiac output and lower peripheral resistance levels during the stress tasks, indicating a challenge rather than a threat profile. Findings were robust when controlled for physical activity, smoking, age, and depressive symptoms.

CONCLUSIONS

Life satisfaction could be positively correlated with beneficial hemodynamic stress reactivity, indicating that individuals with higher levels of life satisfaction can more adaptively cope with stress. Increased cardiac output and decreased peripheral resistance during stress may constitute one route through which life satisfaction can benefit health.

Sources and directions of social support and life satisfaction among solitary Chinese older adults in Hong Kong: the mediating role of sense of loneliness

Based on survey data collected from 151 community-dwelling solitary Chinese older adults in Hong Kong, the present study used path analysis to examine the mediating role of sense of loneliness in the relationship between different sources and directions of social support and life satisfaction. The results showed that sense of loneliness mediated the effects of support from families, friends, and support for others on life satisfaction. In addition, a formal source of social support was not associated with life satisfaction among solitary older adults, although those with a more secure financial status had greater overall life satisfaction. These findings highlight the importance of enhancing awareness among social and health care service providers about the negative effects of insufficient social support on older adults' sense of loneliness and life satisfaction. Family and friendship networks should be expanded for solitary older adults.

Relationship between Adherence to the Mediterranean Diet and Health-Related Quality of Life and Life Satisfaction among Older Adults

OBJECTIVES

Evaluate the relationship between adherence to the Mediterranean diet and health-related quality of life and degree of life satisfaction among older adults.

DESIGN AND SETTING

Cross-sectional descriptive study.

PARTICIPANTS

A total of 351 people older than 60 years participated in the study.

MEASUREMENTS

The Mediterranean Diet Score (MDS) was calculated to assess the degree of adherence to the MD. MD adherence was related to health-related quality of life using the Short Form Healthy Survey (SF-12) questionnaire, to life satisfaction using the Satisfaction with Life Scale (SWLS), and to sociodemographic, clinical and lifestyle variables. Multiple logistic regression models were used to analyse this relationship.

RESULTS

Mediterranean diet adherence was related to health- related quality of life. Participants with better adherence to the MD were more physically active (p=0.01) and had better health-related quality of life (p<0.05) and lower consumption of alcoholic beverages (p=0.04). The age-adjusted model showed a significant association between the MD and mental function for both sexes and with physical function only for men. The fully adjusted model showed a direct relationship between the MD and life satisfaction of women (p>0.05) but not for that of men (p=0.31).

CONCLUSIONS

The adherence to the MD is directly associated with the self-perceived physical and mental function of both sexes and with the life satisfaction of women. Further studies in older adult populations should be performed to obtain conclusive results on the MD effect on health-related quality of life, including wellness indicators.

Poverty, deprivation and life satisfaction among Hong Kong older persons

This investigation examines the association of four measures of poverty (income-based, expenditure-based and asset-based poverty, and material deprivation) with life satisfaction. Perceived life satisfaction was measured among 1,410 older Chinese persons aged 65 and over. Besides life satisfaction and measures of poverty, the study assessed socio-demographic variables, financial strain, health indicators, and social and community resources. Those who faced expenditure-based poverty, material deprivation and asset-based poverty reported a significantly lower level of perceived life satisfaction, while the association between expenditure-based poverty and life satisfaction was found to be the strongest. Other factors that had an impact on life satisfaction included gender, education and marital status; financial strain; social support; the number of close family members and friends; self-rated health; functional capacity; perceived memory; pain; sleep quality; neighbourhood collective efficacy; and engagement in cultural and entertainment activities. From the theoretical perspective, the findings have strong implications for the understanding of the factors that shape the perception of quality of life in old age. Our results also have important policy implications for the official measurement of poverty, monitoring of the poverty situation and the development of anti-poverty measures to help older persons living in poverty to improve the quality of their lives.

Daily Life Satisfaction in Older Adults as a Function of (In)Activity

Objectives

This 14-day daily diary study tested the between-person and within-person associations between sedentary behavior, physical activity, and life satisfaction in community-dwelling older adults.

Method

Older adults (n = 100) wore ActivPAL3 activity monitors for 14 days and, at the end of each day, answered questions regarding their health behaviors and life satisfaction.

Results

Separate multilevel models were tested for self-reported and objectively measured behavioral data. In the model using objectively measured behavioral data, life satisfaction was (a) negatively associated with sedentary behavior at the within-person level and unassociated with sedentary behavior at the between-person level and (b) unassociated with physical activity at either the between-person or within-person level. In the model using self-reported behavioral data, life satisfaction was (a) unassociated with sedentary behavior at either the between-person or within-person level and (2) positively associated with physical activity at the within-person, but not at the between-person, level.

Discussion

Results indicated that daily deviations in objectively measured sedentary behavior and self-reported physical activity have implications for older adults' well-being. Interventions designed to enhance well-being and quality of life in older adults should consider targeting daily changes in total sedentary behavior and daily changes in the volume or frequency of physical activity.

Expanding the Happiness Paradox: Ethnoracial Disparities in Life Satisfaction Among Older Immigrants in the United States

OBJECTIVE

This study investigated nativity disparities in life satisfaction among ethnoracial groups of older adults in the United States and the factors associated with such disparities.

METHOD

Cross-sectional data from 7,348 respondents aged 60 and older from the 2012/2014 waves of the Health and Retirement Study (HRS) were used to estimate linear regression models.

RESULTS

Older immigrants experienced higher levels of life satisfaction than comparable native-born individuals. This "happiness advantage" was particularly salient for Hispanic immigrants, who reported the highest levels of life satisfaction of all groups included in the study. With increasing education, life satisfaction increased for White and "Other Race" groups, regardless of nativity. However, for both Black groups and native-born Hispanics, higher levels of education were associated with lower life satisfaction.

DISCUSSION

Findings suggest that the "happiness paradox" may not only be a matter of Hispanic ethnicity, but that it may also extend to immigrants from other ethnoracial backgrounds.

Factors related to life satisfaction among urban African American adults receiving care at a publicly-funded sexual health clinic

Life satisfaction is linked to premature morbidity and mortality and it may be compromised for individuals living in economically-disadvantaged, urban neighborhoods. The present study explores how behavioral and social-environmental health factors are associated with life satisfaction among a sample of African American young adults. Participants (N = 307, M_age = 26.6 years, 53% male) were recruited from a publicly-funded clinic for a randomized controlled trial (RCT). Data from the baseline assessment of the RCT, which included measures of sleep, depression, anxiety, social support, alcohol and drug use problems, city stress, and life satisfaction, were used for the current study. Correlation analyses assessed bivariate associations between life satisfaction and the demographic and health-related factors. Linear regression using backward elimination determined the best fitting model of factors associated with life satisfaction. Backward elimination resulted in the following variables remaining as significantly associated with life satisfaction: age (b = -2.40, p = .017), anxiety (b = -5.32, p < .001), and social support (b = 2.89, p = .004). Feeling rested upon waking also remained in the best fitting model, although this association did not achieve statistical significance (p = .099). The results suggest that African American adults who are younger, less anxious, and report adequate social support are more likely to report satisfaction with life. These findings add to the literature aimed at examining health and social factors impacting the well-being of African Americans living in low-income, urban communities.

Do past stressful life events and personal control beliefs predict subjective wellbeing in old age? Evidence from a Spanish nationwide representative sample

It has been widely corroborated that recent stressful life events could impact wellbeing; nevertheless, it is not clear whether stressful situations experienced in the past and the individual resources used to deal with them influence older adults’ wellbeing. This study aims to analyse the influence of stressful past events and personal control beliefs, or the extent to which people believe they can control or influence their environment in order to achieve desired outcomes, on negative affect and domain-specific life satisfaction in a cross-sectional sample of 1,177 Spanish people age 50 years and older. For this purpose, the measurement of ten stressful past events, perceived control beliefs, negative affect and life satisfaction were obtained. Preliminary analyses showed that domain-specific life satisfaction grouped into two factors: internal and external life satisfaction. The results of the partial least squares structural equation model indicated that stressful events and control beliefs have an impact on both negative affect and life satisfaction in old age. Stressful past events had a negative effect on life satisfaction, while control beliefs were positively associated with negative affect. The model was able to predict the variance of internal life satisfaction at 37.5 per cent.

Another Paradox? The Life Satisfaction of Older Hispanic Immigrants in the United States

Objective: To investigate disparities in life satisfaction among older Hispanic immigrants in the United States relative to their native-born Hispanic and non-Hispanic White counterparts, and to identify factors associated with such disparities. Method: Cross-sectional data from 9,798 individuals age 60 and above from the Health and Retirement Study (HRS) were used to estimate ordinary least squares (OLS) regression models. Results: Hispanic immigrants reported the highest levels of life satisfaction of all groups. Wealthier older adults, who were socially engaged, had social support, and experienced fewer functional limitations and lower exposure to discrimination, were more satisfied with their lives in the overall sample. Interaction effects revealed that although education was associated with greater life satisfaction only among non-Hispanic Whites, co-residing with children was associated with greater life satisfaction only among Hispanics. Discussion: Although older Hispanic immigrants had the least amount of socioeconomic resources of all groups in our study, they were the most satisfied with their lives. Possible explanations and directions for future research are discussed.

General life satisfaction predicts dementia in community living older adults: a prospective cohort study

BACKGROUND

Low life satisfaction predicts adverse outcomes, and may predict dementia. The objectives were: (1) to determine if life satisfaction predicts dementia over a five year period in those with normal cognition at baseline; and (2) to determine if different aspects of life satisfaction differentially predict dementia.

METHODS

Secondary analysis of an existing population-based cohort study with initial assessment in 1991 and follow-up five years later. Initially, 1,751 adults age 65+ living in the community were sampled from a representative sampling frame. Of these, 1,024 were alive and had complete data at time 2, of whom 96 were diagnosed with dementia. Life satisfaction was measured using the Terrible-Delightful scale, which measures overall life satisfaction on a 7-point scale, as well as various aspects of life satisfaction (e.g. friendships, finances, etc.) Dementia was diagnosed by clinical examination using DSM-IIIR criteria. Logistic regression models were constructed for the outcome of dementia at time 2, and adjusted for age, gender, education, and comorbidities.

RESULTS

Overall life satisfaction predicted dementia five years later, at time 2. The unadjusted Odds Ratio (OR; 95% confidence interval) for dementia at time 2 was 0.72 (0.55, 0.95) per point. The adjusted OR for dementia was 0.70 (0.51, 0.96). No individual item on the life satisfaction scale predicted dementia. However, the competing risk of mortality was very high for some items.

CONCLUSION

A global single-item measure of life satisfaction predicts dementia over a five year period in older adults without cognitive impairment.

Subjective wellbeing and longevity: Findings from a 22-year cohort study

OBJECTIVE

The health implications of positive affect (PA) are still a matter of debate. The present study examined the longitudinal relationships between subjective wellbeing (SWB) components (i.e., Life satisfaction, PA and negative affect (NA)) and all-cause mortality in older adults.

METHODS

Discrete-time survival analysis within the structural equation modeling framework was applied to data from the PAQUID Cohort (n=3777, baseline age 62-101years) including ten time periods spanning 22years. Time-invariant (age, gender, baseline life satisfaction, diabetes mellitus and hypercholesterolemia status) and lagged time-varying (PA, NA, dementia, functional status and self-rated health) predictors were included sequentially in the analyses.

RESULTS

When included together in the model, only PA among the SWB components showed a significant association with longevity, which persisted (OR=.962, 95% CI=.938, .986) even after adjustment for the interaction between PA and NA, and after additional adjustment for prior medical conditions, functional status and self-rated health.

CONCLUSIONS

In congruence with positive psychology, PA proved to be an independent protective factor regardless of variations in NA, which did not seem to be a mortality risk factor.

Associations of sleep duration and sleep quality with life satisfaction in elderly Chinese: The mediating role of depression

This study investigated whether sleep duration and quality were related to life satisfaction (LS) among older Chinese adults and whether depression mediated those relationships. Cross-sectional data from the aging arm of the Rugao Longevity and Aging Study were used. Sleep duration, sleep quality, depression, LS and covariates were analyzed using logistic regressions. To assess the potential mediation of depression on the association between sleep duration and quality and LS, Aroian tests were used. Of 1756 older Chinese adults aged 70-84 years, 90.7% of the men and 83.3% of the women reported being satisfied with their lives. After adjusting for covariates, older adults who slept ≤6h per night were more likely to suffer from life dissatisfaction compared with those who slept 7-8h (OR=2.67, 95% CI 1.86-3.79), and individuals who slept poorly were almost 2 times (OR=2.91, 95% CI 2.16-3.91) more likely to have life dissatisfaction. The Aroian tests confirmed that these relationships were partially mediated by depression (p<0.001). Between short sleep and LS, the mediating effect of depression accounted for 13.9% of the total effects. Moreover, the mediating effect of depression on the association between sleep quality and LS was 13.3%. Short sleep duration and poor sleep quality were inversely associated with LS, and the relationships were partially mediated by depression. Our study suggests that both sleep and depression status are important factors for LS among the elderly.

Social Support Buffers the Impact of Depressive Symptoms on Life Satisfaction in Old Age

OBJECTIVES

Life satisfaction is an important component of overall well-being. Decline in life satisfaction is related to many adverse health outcomes including mortality.

METHODS

We investigate the association of various psychosocial and health-related factors to life satisfaction in 237 non-demented community-dwelling older adults.

RESULTS

Lower levels of depressive symptoms, less perceived stress, higher levels of social support, and better self-perceived general health were significantly associated with higher life satisfaction. Social support buffered the adverse impact of depressive symptoms on life satisfaction where more depressive symptoms were associated with much lower life satisfaction at low levels of social support than at high levels of social support.

DISCUSSION

We discuss study implications, future research directions, and possible interventions that involve boosting social support in at-risk older adults.

Subjective well-being and hookah use among adults in the United States: A nationally-representative sample

BACKGROUND

Using a nationally-representative dataset of adults 18-30 years old in the United States, this study examined the relationship between hookah use and subjective well-being. Levels of sadness, happiness, tiredness, pain, and stress were compared between persons who have used hookah and those who have not.

METHODS

Data were merged from the Tobacco Use Supplement of the Current Population Survey, the American Time Use Survey, and the Subjective Well-being Supplement to the American Time Use Survey for the years 2010-2012 for persons 18-30 years old (n=1147). Wald tests were used to compare mean differences in subjective well-being between hookah users and non-users. Lastly, multivariable regression was used to determine whether there were significant differences in subjective well-being between hookah users and non-users, controlling for demographic factors, self-perceived health, and cigarette smoking.

RESULTS

The lifetime prevalence rate of hookah use was 5.2% among 18-30 year olds. Hookah users reported higher levels of stress and sadness than non-users. These relationships remained significant after controlling for demographic characteristics, self-perceived health, and cigarette use. The results were robust to the use of different statistical models, different age cut-offs, the inclusion of additional covariates (such as income and population density), and separate analyses by sex.

CONCLUSIONS

Hookah use is an emerging public health issue associated with increased levels of stress and sadness. Similar to cigarette use, healthcare providers may consider expanding their screening tests to include hookah use. Public policy geared toward greater prevention and control of hookah use is also recommended.
