Welfare regimes modify the association of disadvantaged adult-life socioeconomic circumstances with self-rated health in old age

Can countries shape the association between cumulative adversity and old-age health?

Introduction

The present study examined the relationships of Lifetime Cumulative Adversity (LCA) and country inequalities, as well as the interactions between them, with the self-rated health (SRH) in old age.

Methods

Using data from the Survey of Health, Aging and Retirement in Europe (SHARE), the study regressed self-rated health on Lifetime Cumulative Adversity and country-level inequality indices across European countries in two points in time. The analysis also considered adversity-inequality interactions, controlling for confounders. The sample was comprised of 28,789 adults, aged 50 to 80, from 25 European countries and Israel.

Results

The findings pointed out that LCA is negatively associated with SRH, but democracy and welfare regimes modify the ill effects of LCA on health. These effects are reduced as the LCA level increases. The effects remained significant over two measurement time-points over three years, showing that life-course trajectories may be shaped by individual accumulated risk exposure to stress, along with inequalities at the society level.

Discussion

The study provides constructive and important guidance for decreasing the harmful effect of lifetime adversity in old age, by the modification of the country's welfare policies.

Physical activity mediates the effect of education on mental health trajectories in older age

OBJECTIVE

Why people with lower levels of educational attainment have poorer mental health than people with higher levels can partly be explained by financial circumstances. However, whether behavioral factors can further explain this association remains unclear. Here, we examined the extent to which physical activity mediates the effect of education on mental health trajectories in later life.

METHODS

Data from 54,818 adults 50 years of age or older (55 % women) included in the Survey of Health, Aging and Retirement in Europe (SHARE) were analyzed using longitudinal mediation and growth curve models to estimate the mediating role of physical activity (baseline and change) in the association between education and mental health trajectories. Education and physical activity were self-reported. Mental health was derived from depressive symptoms and well-being, which were measured by validated scales.

RESULTS

Lower education was associated with lower levels and steeper declines in physical activity over time, which predicted greater increases in depressive symptoms and greater decreases in well-being. In other words, education affected mental health through both levels and trajectories of physical activity. Physical activity explained 26.8 % of the variance in depressive symptoms and 24.4 % in well-being, controlling for the socioeconomic path (i.e., wealth and occupation).

CONCLUSIONS

These results suggest that physical activity is an important factor in explaining the association between low educational attainment and poor mental health trajectories in adults aged 50 years and older.

The Long Arm of Childhood: Does It Vary According to Health Care System Quality?

Increasing evidence points to the salience of early life experiences in shaping health inequalities, but scant research has considered the role of institutional resources as buffers in this relationship. Health care systems in particular are an understudied yet important context for the generation of inequalities from childhood into adulthood. This research investigates associations between childhood disadvantage and adult morbidity and examines the role of health care system quality in this relationship. We also consider the role of adult socioeconomic status. We merge individual-level data on major disease (2014 European Social Survey) with nation-level health care indicators. Results across subjective and objective approaches to health care system quality are similar, indicating a reduced association between childhood socioeconomic status and adult disease in countries with higher quality health care. In total, our results reiterate the long-term influence of childhood disadvantage on health while suggesting health care's specific role as an institutional resource for ameliorating life course health inequalities.

Health among workers retiring after the state pension age: a longitudinal and comparative study

BACKGROUND

In recent decades, many countries have observed increasing labor force participation beyond the state pension age (SPA). However, there is a lack of research on employment beyond SPA and how it relates to older workers' health. Moreover, there is a need to better understand how institutional factors affect the relationship between older workers' employment and health. In this study, we examine simultaneous employment and health trajectories over 11 years in 12 countries from Europe and the Americas, and study how these trajectories differ by welfare state regime and level of old-age pension redistribution.

METHODS

We used a harmonized pooled-country dataset of 3699 older workers based on four representative panel surveys: the Survey of Health, Ageing and Retirement in Europe (SHARE), the English Longitudinal Study of Ageing (ELSA), the Health and Retirement Survey (HRS), and the Chilean Social Protection Survey (EPS). We conducted multichannel sequence analysis to estimate the types of simultaneous employment-health trajectories, and multinomial regression analysis to examine the relationship between trajectory types and institutional factors.

RESULTS

We found that late retirement was equally associated with poor and good health. There is also a higher prevalence of late retirement trajectories in combination with poor health in liberal welfare regimes and in countries with lower levels of old-age pension redistribution.

CONCLUSION

Our study indicates that nonliberal welfare regimes and redistributive old-age pension policies may be better suited to protect vulnerable workers while providing those in good health with the opportunity to work beyond the SPA.

Better Subjective Sleep Quality Partly Explains the Association Between Self-Reported Physical Activity and Better Cognitive Function

Background: Physical activity has been associated with better cognitive function and better sleep quality. Yet, whether the beneficial effect of physical activity on cognitive function can be explained by an indirect pathway involving better sleep quality is unclear. Objective: To investigate whether sleep quality mediates the association between physical activity and cognitive function in adults 50 years of age or older. Methods: 86,541 community-dwelling European adults were included in the study. Physical activity and sleep quality were self-reported. Indicators of cognitive function (immediate recall, delayed recall, verbal fluency) were assessed using objective tests. All measures were collected six times between 2004 and 2017. The mediation was tested using multilevel mediation analyses. Results: Results showed that self-reported physical activity was associated with better self-reported sleep quality, which was associated with better performance in all three indicators of cognitive function, demonstrating an indirect effect of physical activity on cognitive function through sleep quality. The mediating effect of sleep quality accounted for 0.41%, 1.46%, and 8.88% of the total association of physical activity with verbal fluency, immediate recall, and delayed recall, respectively. Conclusion: These findings suggest that self-reported sleep quality partly mediates the association between self-reported physical activity and cognitive function. These results need to be confirmed by device-based data of physical activity and sleep quality.

Early-Life Socioeconomic Circumstances and Physical Activity in Older Age: Women Pay the Price

Health in older age is shaped by early-life socioeconomic circumstances (SECs) and sex. However, whether and why these factors interact is unclear. We examined a cultural explanation of this interaction by distinguishing cultural and material aspects of SECs in the context of physical activity-a major determinant of health. We used data from 56,331 adults between 50 and 96 years old from the Survey of Health, Ageing and Retirement in Europe (SHARE), a 13-year, large-scale, population-based cohort. Confounder-adjusted logistic linear mixed-effects models showed an association between the cultural aspects of early-life SEC disadvantage and physical activity among women, but it was not consistently observed in men. Furthermore, these associations were compensated for only partially by adult-life socioeconomic trajectories. The material aspects of early-life SECs were not associated with adult-life physical activity. These findings highlight the need to distinguish different aspects of SECs because they may relate to health behaviors in diverse ways.

Social protection expenditure on health in later life in 20 European countries: Spending more to reduce health inequalities

BACKGROUND

This study aims to examine whether higher social protection expenditure reduces the negative association of life-course socioeconomic disadvantages with subjective and objective health status and trajectories in later life.

METHODS

We used SHARE data from participants living in 20 European countries aged 50 to 96. Seven waves allowed to examine the trajectories of health inequalities in later life. We used linear mixed-effects models stratified by sex to examine the association between life-course socioeconomic disadvantage and subjective (self-rated health, SRH, N = 55,443) and objective (grip strength, N = 54,718) health. Cross-level interactions between net social protection expenditure as percentage of gross domestic product and life-course socioeconomic disadvantage tested for the moderating effect of social expenditures on the association of disadvantage with SRH and grip strength in later life.

FINDINGS

Higher social protection expenditure reduced socioeconomic health inequalities in both men and women for grip strength, and in women but not men for SRH. For SRH, the health-inequality-reducing effect of social protection expenditure became weaker with increasing age. This was not observed in grip strength. Some separate expenditure functions (disability, family and children) were found to have inequality-widening effects in men's and women's SRH, which were either offset or overcompensated by the other functions. No inequality-widening effects were observed in grip strength.

INTERPRETATION

Higher social spending reduces life-course socioeconomic inequalities in women's subjective health and in men's and women's objective health. However, some specific social protection policies may have the unintentional effect of increasing inequalities in people's evaluation of their own health.

How democracy alters our view of inequality - and what it means for our health

BACKGROUND

Income inequality is associated with poor health when economic disparities are especially salient. Yet, political institutions may alter this relationship because democracies (as opposed to autocracies) may be more inclined to frame inequalities in negative rather than positive ways. Living in a particular political system potentially alters the messages individuals receive about whether inequality is large or small, good or bad, and this, in turn, might affect whether beliefs about inequality influence health. Further, media coverage of economic inequality may negatively affect health if it contributes toward the general perception that the gap between rich and poor has gone up, even if there has been no change in income differentials.

METHODS

In this study, we explore the relationship between democracy, perceptions of inequality, and self-rated health across 28 post-communist countries using survey and macro-level data, multilevel regression models, and inverse probability weighting to estimate the average treatment effect on the treated.

RESULTS

We find that self-rated health is higher in more democratic countries and lower among people who believe that inequality has risen in the last few years. Moreover, we observe that people in democracies are more likely to learn about rising inequality through watching television and that when they do it has a more harmful effect on their health than when people in autocracies learn about rising inequality through the same channel, suggesting that in countries where there is less trust in the television media learning about rising inequality is not as harmful for health.

CONCLUSIONS

Our results indicate that while democracies are generally good for well-being, they may not be unambiguously positive for health. This does not mean, of course, that inequality is good for health nor that, on average, autocracies have better health than democracies; but rather that being more aware of inequality can negatively affect self-rated health.

Representativeness of Systemic Sclerosis Patients in Interventional Randomized Trials: an analysis of the EUSTAR database

OBJECTIVE

To estimate the extent of and the reasons for ineligibility in randomized controlled trials (RCTs) of systemic sclerosis (SSc) patients included in the EUSTAR database, and to determine the association between patient's features and generalizability of study results.

METHODS

We searched Clinicaltrials.gov for all records on interventional SSc-RCTs registered from January 2013 to January 2018. Two reviewers selected studies, and information on the main trial features were retrieved. Data from 8046 patients having a visit in the EUSTAR database since 2013 were used to check patient's eligibility. The proportion of potentially eligible patients per trial, and the risk factors for ineligibility were analyzed. Complete-, worst- and best-case analyses were performed.

RESULTS

Of the 37 RCTs included, 43% were conducted in Europe, 35% were industry-funded, and 87% investigated pharmacological treatments. Ninety-one percent of 8046 patients included could have participated in at least one RCT. In complete-case analysis, the median [range] proportion of eligible patients having the main organ complication targeted by each study was 60% [10-100] in the overall sample of trials, ranging from 50% [32-79] for trials on skin fibrosis to 90% [34-77] for those targeting Raynaud's phenomenon. Among the criteria checked, treatment- and safety-related but not demographic were the main barriers to patient's recruitment. Older age, absence of Raynaud's phenomenon, and lower mRSS were independently associated with the failure to fulfill criteria for any of the included studies.

CONCLUSIONS

Patient's representativeness in SSc-RCTs is highly variable and is driven more by treatment- and safety-related rather than demographic criteria.

The role of welfare regimes in the relationship between childhood economic stress and adult health: a multilevel study of 20 European countries

Childhood economic conditions are important for adult health, and welfare regimes may modify this relationship by altering exposure to social determinants of health. We examine the association between childhood economic stress (CES) and self-rated health (SRH) and cancer (any type), and how welfare regimes may influence these associations. We used data from European Social Survey round 7. Our study is based on 30 024 individuals between 25 to 75 years from 20 European countries grouped into five welfare regimes (Scandinavian, Anglo-Saxon, Bismarckian, Southern and Eastern). Multilevel models were used to assess the association between CES and SRH/cancer, and interactions between CES and welfare regimes. CES increased the risk of poor SRH (RR 1.41, 95% CI 1.29–1.54) and cancer (RR 1.19, 95% CI 1.02–1.37). Controlling for adult socioeconomic status slightly reduced risk for poor SRH, but not cancer. CES increased the probability of poor SRH in the Southern and Eastern regime, and the probability of cancer in the Anglo-Saxon regime, relative to the Scandinavian regime. Childhood economic stress increases the risk of poor self-rated health and cancer. More comprehensive welfare states mitigate these associations, which emphasizes the impact of welfare policies on long-term health outcomes of childhood economic conditions.

Exposure to discrimination and subsequent changes in self-rated health: prospective evidence from the UK's Life Opportunities Survey

OBJECTIVES

We sought to estimate risk of poor self-rated health (SRH) following exposure to disability-related and other forms of overt discrimination in a cohort of working age adults.

STUDY DESIGN

The study design is a population-based cohort survey.

METHODS

Secondary analysis of data collected in Waves 1 and 2 of the UK's Life Opportunities Survey which at Wave 2 involved the participation of 12,789 working age adults. Adjusted prevalence rate ratios were used to estimate the impact of exposure to disability and non-disability discrimination on two measures of SRH at Wave 2, controlling for SRH status at Wave 1.

RESULTS

Exposure to disability discrimination in the previous year was reported by 3.9% of working age British adults. Other forms of discrimination were reported less frequently (age: 3.7%, ethnicity: 2.5%, gender: 1.6%, religion: 0.8%, sexual orientation: 0.4%). In all analyses, there were stronger associations between exposure to disability discrimination and poor SRH at Wave 2 when compared with exposure to other forms of discrimination.

CONCLUSIONS

Disability discrimination represents a violation of human rights. It is also likely to be a major contributor to the health inequities experienced by working age adults with disability.

Do Welfare Regimes Moderate Cumulative Dis/advantages Over the Life Course? Cross-National Evidence from Longitudinal SHARE Data

OBJECTIVES

This study aimed to examine the cumulative disadvantage of different forms of childhood misfortune and adult-life socioeconomic conditions (SEC) with regard to trajectories and levels of self-rated health in old age and whether these associations differed between welfare regimes (Scandinavian, Bismarckian, Southern European, and Eastern European).

METHOD

The study included 24,004 respondents aged 50-96 from the longitudinal SHARE survey. Childhood misfortune included childhood SEC, adverse childhood experiences, and adverse childhood health experiences. Adult-life SEC consisted of education, main occupational position, and financial strain. We analyzed associations with poor self-rated health using confounder-adjusted mixed-effects logistic regression models for the complete sample and stratified by welfare regime.

RESULTS

Disadvantaged respondents in terms of childhood misfortune and adult-life SEC had a higher risk of poor self-rated health at age 50. However, differences narrowed with aging between adverse-childhood-health-experiences categories (driven by Southern and Eastern European welfare regimes), categories of education (driven by Bismarckian welfare regime), and main occupational position (driven by Scandinavian welfare regime).

DISCUSSION

Our research did not find evidence of cumulative disadvantage with aging in the studied life-course characteristics and age range. Instead, trajectories showed narrowing differences with differing patterns across welfare regimes.

Life-Course Circumstances and Frailty in Old Age Within Different European Welfare Regimes: A Longitudinal Study With SHARE

OBJECTIVES

This study aimed to assess whether cumulative disadvantage in childhood misfortune and adult-life socioeconomic conditions influence the risk of frailty in old age and whether welfare regimes influence these associations.

METHOD

Data from 23,358 participants aged 50 years and older included in the longitudinal SHARE survey were used. Frailty was operationalized according to Fried's phenotype as presenting either weakness, shrinking, exhaustion, slowness, or low activity. Confounder-adjusted mixed-effects logistic regression models were used to analyze associations of childhood misfortune and life-course socioeconomic conditions with frailty.

RESULTS

Childhood misfortune and poor adult-life socioeconomic conditions increased the odds of (pre-)frailty at older age. With aging, differences narrowed between categories of adverse childhood experiences (driven by Scandinavian welfare regime) and adverse childhood health experiences (driven by Eastern European welfare regime), but increased between categories of occupational position (driven by Bismarckian welfare regime).

DISCUSSION

These findings suggest that childhood misfortune is linked to frailty in old age. Such a disadvantaged start in life does not seem to be compensated by a person's life-course socioeconomic trajectory, though certain types of welfare regimes affected this relationship. Apart from main occupational position, our findings do not support the cumulative dis/advantage theory, but rather show narrowing differences.

The effect of welfare reform on the health of the unemployed: evidence from a natural experiment in Germany

BACKGROUND

Over the past several decades, governments have enacted far-reaching reforms aimed at reducing the generosity and coverage of welfare benefits. Prior literature suggests that these policy measures may have deleterious effects on the health of populations. In this study, we evaluate the impact of one of the largest welfare reforms in recent history-the 2005 Hartz IV reform in Germany-with a focus on estimating its effect on the health of the unemployed.

METHODS

We employed a quasi-experimental difference-in-differences (DID) design using population-based data from the German Socio-Economic Panel Study, covering the period between 1994 and 2016. We applied DID linear probability modelling to examine the association between the Hartz IV reform and poor self-rated health, adjusting for a range of demographic and socioeconomic confounders.

RESULTS

The Hartz IV reform was associated with a 3.6 (95% CI 0.9 to 6.2) percentage point increase in the prevalence of poor self-rated health among unemployed persons affected by the reform relative to similar but unaffected controls. This negative association appeared immediately following the implementation of the reform and has persisted over time.

CONCLUSION

Governments in numerous European and North American jurisdictions have introduced measures to further diminish the generosity and coverage of welfare benefits. In line with growing concerns over the potential consequences of austerity and associated policy measures, our findings suggest that these reform efforts pose a threat to the health of socioeconomically disadvantaged populations.

Childhood and adulthood circumstances predicting affective suffering and motivation among older adults: a comparative study of European welfare systems

The aims of the study are, first, to examine the effect of childhood and adulthood predictors on affective suffering and motivational symptoms among older adults in Europe and, second, to assess differentials across European welfare systems. The mediating role of adulthood circumstances is also explored. Data are derived from the Survey of Health, Ageing and Retirement in Europe (SHARE) waves 2 (cross-sectional material) and 3 (retrospective information). The sample includes 23,050 respondents aged 50 +. The EUROD subscales were obtained using factor analysis; scores were transformed to binary constructs; logistic regression models were used to identify predictors; mediation was assessed employing a decomposition technique. Prevalence of both subscales is higher in Southern and Central/Eastern Europe and lower in Nordic countries, which are characterised by more equitable and generous welfare provisions. Though health, childhood socioeconomic status and childhood adversity are significant for both subscales, there are also differences; female gender, adulthood socioeconomic status and stress are associated with affective suffering, whereas age and educational attainment are of greater consequence for motivational symptoms. These findings are quite consistent across regions, indicating that the subscales represent different aspects of depression. By contrast, childhood circumstances are attenuated differentially by adulthood factors across Europe. Nevertheless, important mediating circumstances are stress for affective suffering and poor health for motivational symptoms. The importance of childhood circumstances in all aspects of later life mental health highlights the need for policy interventions across welfare systems, which should target vulnerable groups early in life.

Early-life socioeconomic circumstances explain health differences in old age, but not their evolution over time

BACKGROUND

Early-life socioeconomic circumstances (SEC) are associated with health in old age. However, epidemiological evidences on the influence of these early-life risk factors on trajectories of healthy ageing are inconsistent, preventing drawing solid conclusion about their potential influence. Here, to fill this knowledge gap, we used a statistical approach adapted to estimating change over time and an outcome-wide epidemiology approach to investigate whether early-life SEC were associated with the level of and rate of decline of physical, cognitive and emotional functioning over time.

METHODS

We used data on more than 23 000 adults in older age from the Survey of Health, Ageing and Retirement in Europe, a 12-year large-scale longitudinal study with repeated measurements of multiple health indicators of the same participants over time (2004 -2015, assessments every 2 years). Confounder-adjusted linear growth curve models were used to examine the associations of early-life SEC with the evolution of muscle strength, lung function, cognitive function, depressive symptoms and well-being over time.

RESULTS

We consistently found an association between early-life SEC and the mean levels of all health indicators at age 63.5, with a critical role played by the cultural aspect of disadvantage. These associations were only partly explained by adult-life SEC factors. By contrast, evidences supporting an association between early-life SEC and the rate of change in health indicators were weak and inconsistent.

CONCLUSIONS

Early-life SEC are associated with health in old age, but not with trajectories of healthy ageing. Conceptual models in life course research should consider the possibility of a limited influence of early-life SEC on healthy ageing trajectories.
