Prospective association between self-reported life satisfaction and mortality: results from the MONICA/KORA Augsburg S3 survey cohort study

The impact of a diabetes diagnosis on health and well-being: Findings from the English Longitudinal Study of Ageing

BACKGROUND

Poorer health and well-being are associated with diabetes risk. However, little is known about the trajectory of health and well-being from before to after diabetes diagnosis. We compared depressive symptoms, quality of life, self-rated health, and loneliness at three time points (prediagnosis, diagnosis, 2-4 years post diagnosis) in individuals who developed diabetes and a comparison group.

METHODS

Health and well-being measures were self-reported by 3474 participants from the English Longitudinal Study of Ageing. Repeated measures analysis of variance and generalized estimating equations were used to investigate differences by group, time, and group-by-time interactions.

RESULTS

A total of 473 (13.6%) participants developed diabetes. The diabetes group reported greater depressive symptoms (W2(1) = 20.67, p < .001) and lower quality of life (F = 1, 2535 = 10.30, p = .001) and were more likely to rate their health as fair/poor (W2(1) = 67.11, p < .001) across time points, adjusting for age, sex, and wealth. They also reported greater loneliness (F = 1, 2693 = 9.70, p = .002) in unadjusted analyses. However, this was attenuated to the null in adjusted analyses. The group-by-time interaction was significant for quality of life (F = 1.97, 5003.58 = 5.60, p = .004) and self-rated health (W2(2) = 11.69, p = .003), with a greater decline in these measures over time in the diabetes group in adjusted analyses.

CONCLUSION

People who received a diabetes diagnosis had greater depressive symptoms, lower quality of life, and poorer self-rated health than those who did not develop diabetes. Quality of life and self-rated health deteriorated more rapidly following a diagnosis. Screening for these factors around the time of diagnosis could allow for interventions to improve the health and well-being of those with diabetes.

Association of Outdoor Physical Activity and Sports with Life Satisfaction among Women of Reproductive Age According to a European Representative Sample-A Longitudinal Analysis

(1) Background: Low life satisfaction (LS) is associated with impaired mental and physical health. Outdoor physical activity (PA) has diverse somatic and psychological benefits. This study aimed to analyse the associations between sports settings and LS in women of reproductive age. (2) Methods: Special Eurobarometer on Sport and Physical Activity (2022, 2018, 2013) data on regularity and settings of sports/PA, LS and sociodemographic variables were analysed. The representative sample consisted of 18,489 women (34.60 ± 9.36 years). Pearson χ2 test and multivariate logistic regression analysis were conducted, using IBM SPSS version 28.0 according to the STROBE guidelines. The significance level was set at p < 0.05. (3) There was a significant difference in LS based on sports settings (χ2 = 409.696, p < 0.001). In the outdoor group, a 21.4% higher probability of being "very satisfied" compared to the non-outdoor, 30.0% higher compared to the inactive group, was found (R2N = 0.151). Dividing the sample by age, a significant effect remained in middle adulthood (35-44 years p = 0.002 and 45-49 years p = 0.033). (4) Conclusions: Our results underline the importance of the promotion of outdoor, green exercise and the development of special interventions to maintain or improve the psychological well-being of women in reproductive age.

Ambition or comparison? Socioeconomic status and wellbeing differences between local and migrant workers

Pursuing wellbeing is an essential part of human life and plays a determining role in public health and social sustainability. Prior research identified objective socioeconomic status (O-SES), such as real income and homeownership, as facilitators of human subjective wellbeing (SWB). However, not all humans with better SES reported high SWB. This paper expects that subjective socioeconomic status (S-SES) is the key path through which O-SES shapes SWB and that this indirect relationship varies by household registration status, length of residentship, and type of migrant status. Based on a national representative survey dataset-China General Social Survey 2010 (CGSS), the results of generalized structural equation modeling (GSEM) show that household income and homeownership as O-SES are positively related to SWB. Self-evaluated household SES as an important indicator of S-SES not only has a positive relationship with SWB but also significantly mediates the relationship between O-SES and SWB, especially for the new-local residents (NLRs), urban-to-urban migrants (UUMs) and rural-to-urban migrants (RUMs). This study has substantial implications for targeting the comparative psychology and sustainable productivity of Chinese migrants and the local labor force since it is currently facing a growing aging society.

Happy people live longer because they are healthy people

OBJECTIVES

Higher levels of happiness are associated with longer life expectancy. Our study assessed the extent to which various factors explain the protective effect of happiness on all-cause mortality risk, and whether the association differs between older men and women.

METHODS

Using data from the Singapore Longitudinal Aging Studies (N = 6073) of community-dwelling older adults aged ≥ 55 years, we analyzed the association of baseline Likert score of happiness (1 = very sad to 5 = very happy) and mortality from mean 11.7 years of follow up. Cox regression models were used to assess the extent to which confounding risk factors attenuated the hazard ratio of association in the whole sample and sex-stratified analyses.

RESULTS

Happiness was significantly associated with lower mortality (p < .001) adjusted for age, sex and ethnicity: HR = 0.85 per integer score and HR = 0.57 for fairly-or-very happy versus fairly-or-very sad. The HR estimate (0.90 per integer score) was modestly attenuated (33.3%) in models that included socio-demographic and support, lifestyle or physical health and functioning factor, but remained statistically significant. The HR estimate (0.94 per integer score) was substantially attenuated (60%) and was insignificant in the model that included psychological health and functioning. Including all co-varying factors in the model resulted in statistically insignificant HR estimate (1.04 per integer score). Similar results were obtained for HR estimates for fairly-to-very happy versus fairly-to- very sad).

DISCUSSION

Much of the association between happiness and increased life expectancy could be explained by socio-demographic, lifestyle, health and functioning factors, and especially psychological health and functioning factors.

The effect of "Elder Care by Elderly People Program" on life satisfaction and quality of life among institutionalized senior citizens

INTRODUCTION

Improving participation in life meaningful roles is one of the most important predictors of quality of life (QOL) and life satisfaction (LS) in later life. The purpose of this study was to investigate the effect of Elder Care by Elderly People (ECP) on LS and QOL among institutionalized senior citizens.

MATERIAL AND METHOD

This was an interventional study involving a targeted sample of 36 older adults in Ghods nursing home in Tehran in 2018. WHOQOL-OLD 24-item and LS 40-item questionnaires were used to measure LS and Olathe repeated-measures ANOVA and descriptive was employed to obtain the objectives.

RESULTS

The participants were 36 older adults in Ghods nursing home. The mean age of older adults was 67.27 (standard deviation [SD] = 7.6), of whom about 77.8% were male. The mean score of QOL increased from 74.38 (SD = 13.09) pre intervention to 83.72 (SD = 11.43) 2 months post intervention, with most significant change of 9.3 QOL points between pre intervention and 2 months post intervention alone (P < 0.01). Similarly, LS increased from 114.19 (SD = 26.93) pre intervention to 133.94 (SD = 20.49) 2 months post intervention, with most significant change of 19.7 LS points between pre intervention and 2 months post intervention alone (P < 0.001).

CONCLUSIONS

The results of this study showing the evidence of the positive impact of the ECP Programmed for the elderly, therefore, it is suggested that the programmer is evaluated in future studies.

The Role of Psychological and Social Well-being on Physical Function Trajectories in Older Adults

BACKGROUND

Psychological and social well-being are emerging as major determinants in preserving health in old age. We aimed to explore the association between these factors and the rate of decline in physical function over time in older adults.

METHODS

Data were gathered from the Swedish National study on Aging and Care in Kungsholmen (SNAC-K). The study population consisted of 1,153 non-demented, community-dwelling men and women free from multimorbidity or impairments in basic or instrumental activities of daily living at baseline. They were followed over 12 years to capture the rate of decline in physical function, which was measured by combining data on walking speed, balance, and chair stands. The association between baseline psychological and social well-being and decline in physical function was estimated through linear mixed models, after multiple adjustments including personality and depressive symptoms.

RESULTS

Higher levels of psychological (β = .007; p = .037) and social (β = .008; p = .043) well-being were significantly associated with a decreased rate of decline in physical function over the follow-up. There was a significant three-way interaction between psychological well-being*time*sex (female vs male) (β = .015; p = .047), showing that a slower decline in physical function was observed only among women and not in men. The association was strongest for individuals with high levels of both psychological and social well-being (β = .012; p = .019).

CONCLUSION

High levels of psychological and social well-being may slow down the age-related decline in physical function, which confirms the complexity of older adults' health, but also points towards new preventative strategies.

Prediction of Life Satisfaction in People with Parkinson's Disease

Introduction

People with Parkinson's disease (PD) have lower life satisfaction (LS) than healthy peers. No study has yet identified predictors of LS in people with PD. Such information would be valuable for health care and future interventions that aim to maintain or increase LS.

Aim

To examine how LS evolved in people with PD over a 3-year period, as well as to identify predictive factors of LS.

Methods

We used data from baseline assessments and a 3-year follow-up of 163 people with PD (baseline, mean age 68 years; median PD duration 8 years, 35% women). LS was assessed with item 1 of the Life Satisfaction Questionnaire (LiSat-11). Dichotomized LS data from the 3-year follow-up were used as the dependent variable in multivariable logistic regression analyses. In the first step, independent variables included baseline information on sex, education, general self-efficacy, motor symptoms, perceived walking difficulties, fall-related activity avoidance, and difficulties with/need help in activities of daily living. At the second step, depressive symptoms were added as an independent variable.

Results

The proportion of those who reported being satisfied with their lives reduced from 63.2% at baseline to 49.7% 3 years later (p=0.003). When depressive symptoms were not included in the analysis, general self-efficacy (odds ratio, OR = 1.081; 95% CI = 1.019–1.147) and perceived walking difficulties (OR = 0.962; 95% CI = 0.929–0.997) were significant (p < 0.05) predictors of LS 3 years later. With depressive symptoms included, the influence of walking difficulties diminished, and depressive symptoms (OR = 0.730; 95% CI = 0.607–0.877) and general self-efficacy (OR = 1.074; 95% CI = 1.010–1.142) were the only significant predictors of LS 3 years later.

Conclusions

LS is reduced over a 3-year period. The study suggests that perceived walking difficulties, general self-efficacy, and depressive symptoms are important predictors of LS in people with PD.

Estimating expected life-years and risk factor associations with mortality in Finland: cohort study

OBJECTIVE

To develop a tool to inform individuals and general practitioners about benefits of lifestyle changes by providing estimates of the expected age of death (EAD) for different risk factor values, and for those who plan and decide on preventive activities and health services at population level, to calculate potential need for these.

DESIGN

Prospective cohort study to estimate EAD using a model with 27 established risk factors, categorised into four groups: (1) sociodemographic background and medical history, (2) lifestyles, (3) life satisfaction, and (4) biological risk factors. We apply a Poisson regression model on the survival data split into 1-year intervals.

PARTICIPANTS

Total of 38 549 participants aged 25-74 years at baseline of the National FINRISK Study between 1987 and 2007.

PRIMARY OUTCOME MEASURES

Register-based comprehensive mortality data from 1987 to 2014 with an average follow-up time of 16 years and 4310 deaths.

RESULTS

Almost all risk factors included in the model were statistically significantly associated with death. The largest influence on the EAD appeared to be a current heavy smoker versus a never smoker as the EAD for a 30-year-old man decreased from 86.8 years, which corresponds to the reference values of the risk factors, to 80.2 years. Diabetes decreased EAD by >6.6 years. Whole or full milk consumers had 3.4 years lower EAD compared with those consuming skimmed milk. Physically inactive men had 2.4 years lower EAD than those with high activity. Men who found their life almost unbearable due to stress had 2.8 years lower EAD.

CONCLUSIONS

The biological risk factors and lifestyles, and the factors connected with life satisfaction were clearly associated with EAD. Our model for estimating a person's EAD can be used to motivate lifestyle changes.

Life satisfaction: Study of the predictors in a mixed Portuguese sample

Aim

Life satisfaction has been a central research topic in the field of Health Psychology, as an essential construct to individual adaptive psychological functioning. This paper aims to study the predictors of life satisfaction in a mixed sample, verifying the continuity of satisfaction with life in populations of patients with psychiatric disorders and healthy controls.

Method

It was used a mixed sample of non-clinical participants (n = 228) and clinical participants with psychiatric illness (n = 183) from Azores (Portugal). Correlation analyses and, subsequently, multiple linear regression analyses were carried out to study the predictors of satisfaction with life.

Results

Depression and the satisfaction of basic psychological needs were the best predictors of life satisfaction.

Conclusion

Psychological disorders constitute a vulnerability factor for dissatisfaction with life. Therefore, prevention or education and the promotion of adaptive coping strategies for adverse life situations is imperative for improving satisfaction with life, particularly in individuals affected with psychiatric illness.

Association of environmental and sociodemographic factors with life satisfaction in 27 European countries

BACKGROUND

Life satisfaction is a cognitive and evaluative judgement of one's outlook on life and an integral component of subjective wellbeing. There is a strong association between life satisfaction and mental and physical health, but it is currently unclear how environmental factors may influence life satisfaction. Our aim was to investigate the association between environmental factors and life satisfaction and to gain a better understanding of general life satisfaction statistics in the EU.

METHODS

We used a three-level mixed effects logistic regression model to examine the effects of sociodemographic, macroeconomic and environmental factors on life satisfaction using a large sample size from Eurobarometer surveys (n = 268,696) representative of 27 EU countries. Data were collected through face-to-face interviews between May 2014 and June 2015.

RESULTS

We found wide variation between countries, as well as between regions within the same country with regards to levels of life satisfaction. Having adjusted for individual sociodemographic factors, our analysis did not indicate statistically significant associations of mean temperature and precipitation with life satisfaction. However, there was a statistically significant association between environmental degradation and lower life satisfaction (OR = 0.98; 95% CI: 0.97-1.00). Consistent with existing literature, our results show statistically significant effects of sociodemographic factors such as sex, financial situation and employment on life satisfaction.

CONCLUSIONS

Future research should extend analyses to a wider range of sociodemographic, macroeconomic and geographical variables to gain insight on all possible factors affecting life satisfaction to inform policy makers and ensure higher quality of life, and in turn better mental and physical health.

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.

Sociodemographic, behavioral, and health factors associated with positive self-perceived health of long-lived elderly residents in Florianópolis, Santa Catarina, Brazil

The objective of this study was to identify the factors associated with positive self-perceived health of long-lived elderly (80+) individuals. This cross-sectional study was conducted in the city of Florianópolis, Santa Catarina, Brazil, and included 239 elderly participants from the EpiFloripa Ageing Project. We used collection instruments to verify sociodemographic and economic data, self-reported health status, falls, and lifestyle. Then, we identified factors associated with positive self-perceived health using a Poisson regression adjusted for sex. We found that a positive self-reported health status was more prevalent among the long-lived elderly who were not depressed (PR = 0.49), and among those who consumed alcohol (PR = 1.99). Understanding which variables may interfere in the self-perceived health of the long-lived elderly can result in better health options for this population, mainly, new methods to prevent depression. Additionally, this information can help reduce costs associated with hospitalizations, medications and health treatments, all of which are very common among the long-lived elderly.

How strongly related are health status and subjective well-being? Systematic review and meta-analysis

Background

Health status is widely considered to be closely associated with subjective well-being (SWB), yet this assumption has not been tested rigorously. The aims of this first systematic review and meta-analysis are to examine the association between health status and SWB and to test whether any association is affected by key operational and methodological factors.

Methods

A systematic search (January 1980-April 2017) using Web of Science, Medline, Embase, PsycInfo and Global health was conducted according to Cochrane and PRISMA guidelines. Meta-analyses using a random-effects model were performed.

Results

Twenty nine studies were included and the pooled effect size of the association between health status and SWB was medium, statistically significant and positive (pooled r = 0.347, 95% CI = 0.309-0.385; Q = 691.51, I2 = 94.99%, P < 0.001). However, the association was significantly stronger: (i) when SWB was operationalised as life satisfaction (r = 0.365) as opposed to happiness (r = 0.307); (ii) among studies conducted in developing countries (r = 0.423) than it was in developed countries (r = 0.336) and (iii) when multiple items were used to assess health status and SWB (r = 0.353) as opposed to single items (r = 0.326).

Conclusion

Improving people's health status may be one means by which governments can improve the SWB of their citizens. Life satisfaction might be preferred to happiness as a measure of SWB because it better captures the influence of health status.

"Euphoria" or "Only Teardrops"? Eurovision Song Contest performance, life satisfaction and suicide

Background

The popularity of the Eurovision Song Contest (ESC) in Europe has been high for decades. We aimed to assess whether a country’s performance in the ESC is associated with life satisfaction and suicide mortality in European countries.

Methods

We analysed nationally representative Eurobarometer survey data on life satisfaction from 33 European countries (N = 162,773) and country-level standardised suicide mortality data for years 2009 to 2015. The associations of winning the Contest, performing terribly, and higher final ranking with life satisfaction and suicide rates were all assessed.

Results

Winning the ESC was not statistically significantly associated with increased life satisfaction or suicide rates, although every ten-place increase in final ranking was associated with an increase in life satisfaction (adjusted odds ratios [aOR] 1.04; 95% confidence interval [CI]: 1.02 to 1.05) and a decrease in suicide mortality rates (β = − 0.30; 95% CI: -0.59 to − 0.01). Terrible performance was associated with greater life satisfaction compared to not competing at all (aOR 1.13; 95%CI: 1.07 to 1.20).

Conclusion

The good news for participating countries is that just competing at the ESC is associated with higher life satisfaction among the population. As improved performance is linked to Ooh Aah Just a Little Bit of improved life satisfaction, further research into how such international competitions may impact public health is needed.

Less screen time and more frequent vigorous physical activity is associated with lower risk of reporting negative mental health symptoms among Icelandic adolescents

Objective

Few studies have explored the potential interrelated associations of screen time and physical activity with mental health in youth, particularly using objective methods. We examined cross-sectional associations of these variables among Icelandic adolescents, using objective and subjective measurements of physical activity.

Methods

Data were collected in the spring of 2015 from 315 tenth grade students (mean age 15.8 years) in six elementary schools in metropolitan Reykjavík, Iceland. Participants reported, via questionnaire, on demographics, weekly frequency of vigorous physical activity, daily hours of screen time and mental health status (symptoms of depression, anxiety and somatic complaints, self-esteem and life satisfaction). Total physical activity was measured over one week with wrist-worn accelerometers. Body composition was determined by DXA-scanning. Poisson regression analysis was used to explore independent and interactive associations of screen time and physical activity with mental health variables, adjusting for gender, body fat percentage and maternal education.

Results

Less screen time (below the group median of 5.3 h/day) and more frequent vigorous physical activity (≥4x/week) were each associated with reporting fewer symptoms of depression, anxiety, low self-esteem, and life dissatisfaction. No significant associations were observed between objectively measured physical activity and mental health outcomes. Interactive regression analysis showed that the group reporting both less screen time and more frequent vigorous physical activity had the lowest risk of reporting symptoms of depression, anxiety, low self-esteem, and life dissatisfaction.

Conclusions

Reports of less screen time and more frequent vigorous physical activity were associated with lower risk of reporting mental health problems among Icelandic adolescents. Those who reported a combination of engaging in less screen time and more frequent vigorous physical activity had the lowest risk, suggesting a synergistic relationship between the two behaviors on mental health outcomes. Our results support guiding youth towards more active and less sedentary/screen-based lifestyle.

Life satisfaction is a protective factor against the onset of Type 2 diabetes in men but not in women: findings from the MONICA/KORA cohort study

AIMS

To investigate the association of high life satisfaction with incident Type 2 diabetes separately in men and women.

METHODS

A longitudinal analysis was conducted among the 7107 participants (3664 men, 51.5%; 3443 women, 48.5%) aged 25-74 years (mean ± sd age 47.8 ±13.7 years) of two population-based MONICA/KORA surveys conducted in 1989-1995 and followed up until 2009. Life satisfaction was assessed using a one-item instrument with a six-order response level, which was dichotomized into high vs medium or low. Sex-specific hazard ratios were estimated using Cox proportional hazards models.

RESULTS

Crude incidence rates for Type 2 diabetes per 10 000 person-years were lower in participants with high than in those with medium or low life satisfaction (men: 57 vs 73; women: 37 vs 48). In men with high life satisfaction, there was a 27% risk reduction in incident Type 2 diabetes (hazard ratio 0.73, 95% CI 0.56-0.94; P=0.02) in a model adjusted for sociodemographic, behavioural and clinical risk factors. The association lost statistical significance after further adjusting for depressed mood (hazard ratio 0.79, 95% CI 0.61-1.03). Life satisfaction was not significantly associated with incident Type 2 diabetes in women.

CONCLUSION

Life satisfaction may be a valuable asset in assessing risk of Type 2 diabetes, especially in men, and in the development of more effective prevention strategies to deter onset of diabetes. More research is needed to investigate the underlying potential causal pathways that may link life satisfaction to the development of Type 2 diabetes.

The Impact of Subjective Well-being on Mortality: A Meta-Analysis of Longitudinal Studies in the General Population

OBJECTIVE

The aims of the study were to assess whether subjective well-being is a protective factor for mortality in the general population and to analyze the differential impact of evaluative, experienced, and eudaimonic well-being.

METHODS

Systematic review of articles in the PsycINFO, Web of Science, and PubMed databases. Data on the studies' characteristics, quality, and the effects of variables were extracted. A meta-analysis was conducted on the studies included in the systematic review.

RESULTS

A total of 62 articles that investigated mortality in general populations, involving 1,259,949 participants, were found, and added to those considered in a previously published review (n = 14). The meta-analysis showed that subjective well-being was a protective factor for mortality (pooled hazard ratio = 0.920; 95% confidence interval = 0.905-0.934). Although the impact of subjective well-being on survival was significant in both men and women, it was slightly more protective in men. The three aspects of subjective well-being were significant protective factors for mortality. The high level of heterogeneity and the evidences of publication bias may reduce the generalizability of these findings.

CONCLUSIONS

Our results suggest that subjective well-being is associated with a decreased risk of mortality. Longitudinal studies examining changing levels of well-being and their relationship to longevity would be required to establish a cause-effect relationship. Establishing such a causal relationship would strengthen the case for policy interventions to improve the population subjective well-being to produce longevity gains combined with optimizing quality of life.

Trajectories of Life Satisfaction and their Predictors among Korean Older Adults

BACKGROUND

Among older adults, life satisfaction (LS) correlates with health, mortality, and successful ageing. As various potential threats to LS tend to increase with advancing years, patterns of age-related changes in LS among older adults remain inconsistent. This study aimed to identify LS trajectories in older adults and the characteristics of individuals who experience them.

METHODS

Large-scale, nationally representative, longitudinal data collected from 2005 to 2013 were analyzed for this study. The outcome measure was a summary of multidimensional domains influencing LS: health, finance, housing, neighbor relationships, and family relationships. Latent class growth models and logistic regression models were used to identify trajectory groups and their predictors, respectively.

RESULTS

Within 3517 individuals aged 65 or older, five trajectories were identified across eight follow-up years: "low-stable" (TG1; n = 282; 8%), "middle-stable" (TG2; n = 1146; 32.6%), "improving" (TG3; n = 75; 2.1%), "upper middle-stable" (TG4; n = 1653; 47%), and "high" (TG5; n = 361; 10.3%). High trajectory individuals more frequently had higher education, financial security, good physical health, and good mental health than those in the stable, but less satisfied, groups. Similarly, compared to the largest group (upper middle-stable trajectory), individuals in the low-stable or middle-stable trajectory group not only had poorer physical and mental health but were more likely to be living alone, financially stressed, and residing in urban locations. Individuals with improving trajectory were younger and in poorer mental health at baseline compared to the upper middle-stable trajectory group.

CONCLUSION

Life satisfaction in the older follows distinct trajectories. For older adults, trajectories are stable over time and predictable, in part, from individual characteristics. Knowledge of these patterns is important for effective policy and program development.

The association between occupational secondhand smoke exposure and life satisfaction among adults in the European Union

BACKGROUND

Despite existing legislation, a large proportion of the European Union (EU) population is exposed to occupational secondhand smoke (SHS). The aim of this study was to explore associations between occupational exposure to SHS and self-reported life satisfaction.

METHODS

We analysed data collected through the Eurobarometer survey (wave 82.4) from n = 11,788 individuals working in indoor spaces. The sample was representative of the population of the 28 EU member states. We fitted a multilevel logistic regression model adjusting for smoking, age, gender, occupation, area of residence, education, difficulty paying bills, marital status and social class.

RESULTS

27.5% of those working indoors reported at least some occupational exposure to SHS. People exposed to occupational SHS were less likely to report that they were satisfied with the life they lead (adjusted Odds Ratio = 0.72, 95% Confidence Interval: 0.60-0.87). The effect of occupational exposure on life satisfaction did not differ by smoking status, with all interaction terms between smoking status and occupational exposure to SHS not statistically significant.

CONCLUSION

Exposure to SHS at the workplace does not only have negative consequences on physical health, but it can also impact life satisfaction of smokers and non-smokers. Our findings highlight the need for stricter enforcement of smokefree environments at the workplace in the EU.

Multidimensional construct of life satisfaction in older adults in Korea: a six-year follow-up study

Background

Aging raises wide-ranging issues within social, economic, welfare, and health care systems. Life satisfaction (LS) is regarded as an indicator of quality of life which, in turn, is associated with mortality and morbidity in older adults. The objective of this study was to identify the relevant predictors of life satisfaction and to investigate changes in a multidimensional construct of LS over time.

Methods

This analysis utilized data from the large-scale, nationally representative Korean Retirement and Income Study (KReIS), a longitudinal survey conducted biennially from 2005 to 2011. Outcome measures were degree of satisfaction with health, economic status, housing, neighbor relationships, and family relationships. GEE models were used to investigate changes in satisfaction within each of the five domains.

Results

Of a total 3531 individuals aged 65 or older, 2083 (59%) were women, and the mean age was 72 (s.d = ±6) years. The majority had a spouse (60.8%) and lived in a rural area (58%). Analysis showed that physical and mental health were consistently and significantly associated with satisfaction in each of the domains after adjusting for potential confounders. Living in a rural area and living with a spouse were related to satisfaction with economic, housing, family relationships, and neighbor relationships compared to living in urban areas and living without a spouse; the only outcome that did not show relationship to these predictors was health satisfaction. Female and rural residents reported greater economic satisfaction compared to male and urban residents. Living in an apartment was associated with 1.32 times greater odds of economic satisfaction compared to living in a detached house (95% CI: 1.14–1.53; p < 0.0001). Economic satisfaction was also 1.62 times more likely among individuals living with a spouse compared to single households (95% CI: 1.35–1.96; p < 0.0001). Financial stress index value was found to be a significant predictor of satisfaction with family relationships.

Conclusions

Our study indicates that a single domain of LS or overall LS will miss many important aspects of LS as age-related LS is multi-faceted and complicated. While most studies focus on overall life satisfaction, considering life satisfaction as multidimensional is essential to gaining a complete picture.

Impact of physical and mental health on life satisfaction in old age: a population based observational study

Background

It is widely assumed that poor health lowers life satisfaction when ageing. Yet, research suggests this relationship is not straightforward. This study investigated how older people evaluate their life when facing disease and disabilities.

Methods

The Leiden 85-plus Study, a prospectively followed cohort of a cohort of a middle-sized city in the Netherlands, all aged 85 years, that was age-representative of the general population, was used. Those with severe cognitive dysfunction were excluded (n = 501). Comorbidities, physical performance, cognitive function, functional status, residual lifespan, depressive symptoms and experienced loneliness were measured during home visits. Life satisfaction was self-reported with Cantril’s ladder. All analyses were performed using regression analysis.

Results

Participants reported high life satisfaction (median 8 out of 10 points) despite having representative levels of disease and disability. Comorbidity, low cognitive function, and residual lifespan as markers of health were not associated with life satisfaction. Poor physical performance and low functional status were weakly but significantly associated with lower life satisfaction (p < 0.05 respectively p < 0.001), but significance was lost after adjustment for depressive symptoms and perceived loneliness. Depressive symptoms and perceived loneliness were strongly related to lower life satisfaction (both p < 0.001), even after adjustment for physical health characteristics.

Conclusion

Poor physical health was hardly related to lower life satisfaction, whereas poor mental health was strongly related to lower life satisfaction. This indicates that mental health has a greater impact on life satisfaction at old age than physical health, and that physical health is less relevant for a satisfactory old age.

Joint association of screen time and physical activity on self-rated health and life satisfaction in children and adolescents: the CASPIAN-IV study

BACKGROUND

Self-rated health and life satisfaction are two subjective measures for assessing overall health status. This study aims to investigate the association of self-rated health and life satisfaction with physical activity and screen time.

METHODS

As part of the fourth survey of a national surveillance program in Iran (CASPIAN-IV study), 14 880 students aged 6 to 18 years were selected via multi-stage cluster sampling from 30 provinces. Data were obtained from the WHO Global School-Based Student Health Survey questionnaire.

RESULTS

A total of 13 486 students with mean age of 12.47 (SD 3.36) completed the study. In crude model both prolonged screen time and physical activity were associated with favorable life satisfaction and self-rated health. However, in multivariate analysis only high physical activity was associated with good self-rated health (OR 1.37) and life satisfaction (OR 1.39), while prolonged screen time was not associated with good self-rated health (OR 1.02) and life satisfaction (OR 0.94). For combined screen time-physical activity variable, low screen time-high physical activity combination had the highest OR for both good self-rated health (OR 1.37) and life satisfaction (OR 1.43) in multivariate analysis.

CONCLUSIONS

Our findings suggest that increasing physical activity is more crucial than emphasizing reducing screen time in improving the well-being of children and adolescents.

Positive Affect Is Inversely Associated with Mortality in Individuals without Depression

BACKGROUND

Some studies have analyzed the relation between well-being and mortality but none of them have attempted to disentangle the differential influence that positive affect, negative affect, and evaluative well-being might have on mortality using a longitudinal design in the general population and measuring independently and accurately each component of well-being. The aim of the present study is to assess the association of these well-being components with mortality after adjusting for health and other lifestyle factors and to analyze whether this association is different in people with and without depression.

METHODS

A nationally representative sample of 4753 people from Spain was followed up after 3 years. Analyses were performed with Cox regression models among the total sample and separately in people with and without depression.

RESULTS

In the analyses adjusted for age, sex, and years of education, all three well-being variables showed separately a statistically significant association with mortality. However, after adjustment for health status and other confounders including the other well-being components, only positive affect remained as marginally associated with a decreased risk of mortality in the overall sample [HR = 0.87; 95% CI = 0.73-1.03], in particular among individuals without depression [HR = 0.82; 95% CI = 0.68-0.99].

CONCLUSION

Positive affect is inversely associated with mortality in individuals without depression. Future research should focus on assessing interventions associated with a higher level of positive affect.

Community Resilience throughout the Lifespan--The Potential Contribution of Healthy Elders

An increase in the exposure and predisposition of civilian populations to disasters has been recorded in the last decades. In major disasters, as demonstrated recently in Nepal (2015) and previously in Haiti (2010), external aid is vital, yet in the first hours after a disaster, communities must usually cope alone with the challenge of providing emergent lifesaving care. Communities therefore need to be prepared to handle emergency situations. Mapping the needs of the populations within their purview is a trying task for decision makers and community leaders. In this context, the elderly are traditionally treated as a susceptible population with special needs. The current study aimed to explore variations in the level of community resilience along the lifespan. The study was conducted in nine small to mid-size towns in Israel between August and November 2011 (N = 885). The Conjoint Community Resiliency Assessment Measure (CCRAM), a validated instrument for community resilience assessment, was used to examine the association between age and community resilience score. Statistical analysis included spline and logistic regression models that explored community resiliency over the lifespan in a way that allowed flexible modeling of the curve without prior constraints. This innovative statistical approach facilitated identification of the ages at which trend changes occurred. The study found a significant rise in community resiliency scores in the age groups of 61–75 years as compared with younger age bands, suggesting that older people in good health may contribute positively to building community resiliency for crisis. Rather than focusing on the growing medical needs and years of dependency associated with increased life expectancy and the resulting climb in the proportion of elders in the population, this paper proposes that active "young at heart" older people can be a valuable resource for their community.

Positive self-rated health in the elderly: a population-based study in the South of Brazil

The objective was to identify factors associated with positive self-rated health in the elderly in Florianópolis, Santa Catarina State, in the South of Brazil. This population-based cross-sectional study evaluated 1,705 elderly. Self-rated health was classified as positive (very good or good) or negative (fair, poor, and very poor). Crude and adjusted Poisson regression was used to identify associated factors. Prevalence of positive self-rated health was 51.2%, associated with male gender (PR = 1.13), more than 5 years of schooling, moderate (PR = 1.33) or high alcohol intake (PR = 1.37), leisure-time activity (PR = 1.20), Internet use (PR = 1.21), fewer diseases, mild/moderate dependence (PR = 2.20) or no dependence (PR = 2.67), no falls (PR = 1.19), and non-use of polypharmacy (PR = 1.27). Several modifiable factors were identified that can affect positive self-rated health in the elderly and contribute to the development of strategies to improve their quality of life.

Variability Modifies Life Satisfaction's Association With Mortality Risk in Older Adults

Greater life satisfaction is associated with greater longevity, but its variability across time has not been examined relative to longevity. We investigated whether mean life satisfaction across time, variability in life satisfaction across time, and their interaction were associated with mortality over 9 years of follow-up. Participants were 4,458 Australians initially at least 50 years old. During the follow-up, 546 people died. After we adjusted for age, greater mean life satisfaction was associated with a reduction in mortality risk, and greater variability in life satisfaction was associated with an increase in mortality risk. These findings were qualified by a significant interaction such that individuals with low mean satisfaction and high variability in satisfaction had the greatest risk of mortality over the follow-up period. In combination with mean life satisfaction, variability in life satisfaction is relevant for mortality risk among older adults. Considering intraindividual variability provides additional insight into associations between psychological characteristics and health.

Are total, intensity- and domain-specific physical activity levels associated with life satisfaction among university students?

Background

Thorough information about the relationship between physical activity (PA) and life satisfaction is still lacking. Therefore, this study examined the cross-sectional relationships between life satisfaction and meeting the World Health Organization (WHO) moderate to vigorous-intensity PA recommendations, total volume and duration of PA, intensity-specific PA (walking, moderate- and vigorous-intensity), domain-specific PA (work, transport-related, domestic, and leisure-time), and 11 domain and intensity-specific PA types among university students. Additionally, we examined the associations between life satisfaction and gender, age, disposable income, community size, smoking, alcohol intake, body mass index (BMI), and self-rated health.

Methods

The study included a random sample of 1750 university students in Zagreb, Croatia (response rate = 71.7%; 62.4% females; mean age 21.5 ± 1.8 years), using the International Physical Activity Questionnaire — long form and the Satisfaction with Life Scale.

Results

Higher life satisfaction was associated with female gender (β = 0.13; p = <0.001), younger age (β = -0.07; p = 0.024), higher disposable income (β = 0.10; p = 0.001), and better self-rated health (β = 0.30; p = <0.001). No significant association was found between life satisfaction and size of community (p = 0.567), smoking status (p = 0.056), alcohol consumption (p = 0.058), or BMI (p = 0.508). Among all PA variables, only leisure-time vigorous-intensity PA was significantly associated with life satisfaction after adjustments for socio-demographic characteristics, lifestyle and self-rated general health (β = 0.06; p = 0.045).

Conclusions

This study indicated a weak positive relationship between leisure-time vigorous-intensity PA and life satisfaction, whilst no such association was found for other PA variables. These findings underscore the importance of analyzing domain and intensity-specific PA levels in future studies among university students, as drawing conclusions about the relationship between PA and life satisfaction based on total PA levels only may be misleading.

Mind over hormones: sex differences in associations of well-being with IGF-I, IGFBP-3 and physical activity in the KORA-Age study

OBJECTIVES

A ssociations between well-being, serum levels of insulin-like growth factor 1 (IGF-I), and its primary binding protein IGFBP-3, were examined in an epidemiologic study. The influence of physical activity on the effect of hormones on well-being was considered.

METHODS

Cross-sectional data from participants of the KORA-Age study (n=985, age 64-93) was analyzed in sex-specific multivariable regressions of well-being (World Health Organization (WHO) -5) or ill-being (geriatric depression scale (GDS) -15). Models were adjusted for age, physical activity, sleep, BMI, smoking, and cognition. Adjusted WHO-5 means demonstrated the interaction between hormone quintiles with physical activity.

RESULTS

Full models indicated that increased IGFBP-3 positively associated with well-being in women (β estimate=0.14, standard error (SE)=0.06) and less so in men (β=0.11, SE=0.07). IGF-I associated positively with depression (β=0.11, SE=0.06) and negatively with well-being (β=-0.11, SE=0.06) in women. Similar but not statistically discernable effects were observed in men. Adjusted mean WHO-5 scores illustrated the positive effect of physical activity and IGFBP-3 on well-being in women only.

CONCLUSIONS

Opposite and independent associations of IGF-I and IGFBP-3 on well-being observed in women suggests neuroprotective effects of IGFBP-3 in age.

Teachers' assessments of children's mental problems with respect to adolescents' subsequent self-reported mental health

PURPOSE

To investigate whether teachers' assessments of children are predictive of subsequent self-reported mental problems in adolescence and how these problems are concurrently linked with adolescents' overall life satisfaction.

METHOD

The study subjects originated from the prospective population-based Northern Finland Birth Cohort 1986 (N = 9,432). At age 8 years first-grade students' emotional and behavioral problems were assessed by their teachers with Rutter Children's Behavioural Questionnaires for teachers (RB2). At the age of 16 years, adolescents responded to the eight Youth Self-report (YSR) subscales and the one-item overall life satisfaction scale. Multivariate logistic regression was used to study the longitudinal relationship between RB2 and YSR.

RESULTS

Children who had emotional problems according to their teachers (RB2) were more prone to withdrawal and social problems in adolescence (YSR). Behavioral problems in childhood (RB2) were predictive of attention problems, and delinquent and aggressive behavior (YSR), while hyperactivity (RB2) was only predictive of attention problems and delinquent behavior (YSR). Additionally, each YSR subscale was strongly and linearly associated with concurrent self-reported life satisfaction in adolescence.

CONCLUSIONS

Teachers' assessments of children were predictive of self-reported mental problems in adolescence, which, in turn, were strongly associated with concurrent self-reported life satisfaction. In order to support favorable growth of children to well-adjusted adolescents and to intervene as early as possible in the event of adverse progression, both teachers' assessments of children and adolescent's self-rated overall life satisfaction should be acknowledged.

Life satisfaction and risk of chronic diseases in the European prospective investigation into cancer and nutrition (EPIC)-Germany study

OBJECTIVE

The aim of the study was to examine the prospective association between life satisfaction and risk of type 2 diabetes mellitus, myocardial infarction, stroke, and cancer. Previous studies suggested that psychosocial factors may affect the development of chronic diseases but the impact of positive attitudes, in particular life satisfaction, is yet to be determined.

METHODS

The analysis included 50,358 participants of the European Prospective Investigation into Cancer and Nutrition (EPIC)-Germany study in Potsdam and Heidelberg. Life satisfaction was assessed in a baseline interview and incident cases of chronic diseases were identified and verified during follow-up. Hazard ratios were calculated using Cox proportional hazards regression models that were systematically multivariable-adjusted for established risk factors and prevalent diseases.

RESULTS

During an average of 8 years of follow-up 2,293 cases of cancer, 1,840 cases of type 2 diabetes mellitus, 440 cases of stroke, and 562 cases of myocardial infarction were observed. Women who were unsatisfied with life at baseline showed in all models a significantly increased risk of cancer (HR: 1.45; 95% CI: 1.18-1.78) and stroke (HR: 1.69; 95% CI: 1.05-2.73) as well as an increased risk of type 2 diabetes mellitus by trend across categories (p-trend=0.04) compared to women very satisfied with life. In men, a relationship between life satisfaction and stroke was found but did not persist after consideration of lifestyle factors and prevalent diseases. No significant association was observed between life satisfaction and risk of myocardial infarction.

CONCLUSIONS

The results of this study suggest that reduced life satisfaction is related to the development of chronic diseases--particularly in women and partly mediated by established risk factors.

Biological and other health related correlates of long-term life dissatisfaction burden

BACKGROUND

Mental health is interconnected with somatic health and can manifest itself in biological processes. Life dissatisfaction is an indicator of subjective well-being, but information on its biological correlates is scarce. The aim of this study was to investigate the biological correlates along with other health-related factors of long-term life dissatisfaction in a population-based sample.

METHODS

As part of the Kuopio Depression Study, health questionnaires were sent to a randomly selected population-based sample in 1998, 1999, and 2001. In 2005, among a clinically studied sub-sample (n = 305), the 7-year long-term life dissatisfaction burden was assessed by summing life satisfaction scores from previous health questionnaires. Several sociodemographic, health, health behavior, and biological factors were investigated in respect to their associations to categorized (low and high) and continuous (linear regression) life satisfaction burden score (higher values indicating dissatisfaction).

RESULTS

In the final linear regression model long-term life dissatisfaction burden was significantly associated with poor social support (B = 0.138; p < 0.001), marital status (i.e. living alone) (B = 0.049; p = 0.019), current smoking (B = 0.087; p < 0.001), poor sleep (B = 0.052; p = 0.001), use of statins (B = -0.052; p = 0.002) and lower serum adiponectin level (B = -0.001; p = 0.039) whereas association of metabolic syndrome was marginally nonsignificant (B = 0.029; p = 0.055).

CONCLUSION

Long-term life dissatisfaction is associated with adverse health, health behavioral, and social factors, as well as with a decreased anti-inflammatory buffer capacity, all indicating close relationships between subjective well-being and somatic morbidity.

[Factors associated with life satisfaction in a cohort of older people in Santiago, Chile]

OBJECTIVE

To evaluate the association between life satisfaction and socioeconomic status and self-reported health in a cohort of older people in Santiago, Chile, in 2005 and 2006.

METHODS

We interviewed 2002 individuals aged 65 to 67.9 years registered in 20 primary care centers in the city of Santiago. Participants were living independently with no cognitive impairment, suspected cancer or terminal diseases. We assessed life satisfaction using an abbreviated adaptation of a life satisfaction scale (scored from 0 to 11), and collected self-reported information on income, education, social support, and self-reported health and memory. We used a log-binomial model to analyze the association between life satisfaction scores (fourth quartile compared with the first) and socioeconomic and health variables.

RESULTS

There was a significant association (bivariate and multivariate analyses) between life satisfaction and income in men and with social support, self-reported health, memory, and diagnosis of joint problems, diabetes and hypertension in both sexes.

CONCLUSION

Social support, income and health status were independently associated with life satisfaction in older people aged 65-67.9 years in Santiago. Further studies are required to assess the temporal direction of the effect and the implications of these findings for public health policies in this population.

Life satisfaction and mortality in elderly people: the Kangwha Cohort Study

Background

As well as biomedical risk factors, psychological factors have been reported to be related to mortality rate. The purpose of this study was to examine the relationship between life satisfaction and mortality in elderly people through an 11.8-year follow-up study of a prospective cohort.

Methods

Among 3,600 participants of the Kangwha Cohort Study who survived in 1994, 1,939 respondents of the Life Satisfaction Index (LSI)-A questionnaire were included (men, 821; women, 1118). The mortality risk for the period up to December 2005 was measured using the Cox Proportional Hazard Model.

Results

When the relationship between LSI and mortality was evaluated in men, the unsatisfied group with lower LSI scores showed a significantly higher risk of all-cause mortality (hazard ratio [HR], 1.42; 95% confidence interval [CI], 1.11-1.83) than the satisfied group with higher LSI scores. In women, the unsatisfied group showed a significantly higher risk of all-cause mortality (HR, 1.51; 95% CI, 1.18-1.92) and cardiovascular mortality (HR, 2.23; 95% CI, 1.30-3.85) than the satisfied group.

Conclusion

We found that elderly people with a lower LSI score, regardless of gender, were at risk of increased mortality from all causes, and low LSI score was also associated with cardiovascular mortality.
