Socioeconomic disparities in health among older adults and the implications for the retirement age debate: a brief report

Retirement and cognitive aging in a racially diverse sample of older Americans

BACKGROUND

Retirement represents a crucial transitional period for many adults with possible consequences for cognitive aging. We examined trajectories of cognitive change before and after retirement in Black and White adults.

METHODS

Longitudinal examination of up to 10 years (mean = 7.1 ± 2.2 years) using data from the REasons for Geographic and Racial Differences in Stroke (REGARDS) study-a national, longitudinal study of Black and White adults ≥45 years of age. Data were from 2226 members of the REGARDS study who retired around the time when an occupational ancillary survey was administered. Cognitive function was an average of z-scores for tests of verbal fluency, memory, and global function.

RESULTS

Cognitive functioning was stable before retirement (Estimate = 0.05, p = 0.322), followed by a significant decline after retirement (Estimate = -0.15, p < 0.001). The decline was particularly pronounced in White (Estimate = -0.19, p < 0.001) compared with Black (Estimate = -0.07, p = 0.077) participants, twice as large in men (Estimate = -0.20, p < 0.001) compared with women (Estimate = -0.11, p < 0.001), highest among White men (Estimate = -0.22, p < 0.001) and lowest in Black women (Estimate = -0.04, p = 0.457). Greater post-retirement cognitive decline was also observed among participants who attended college (Estimate = -0.14, p = 0.016). While greater work complexity (Estimate = 0.92, p < 0.05) and higher income (Estimate = 1.03, p < 0.05) were related to better cognitive function at retirement, neither was significantly related to cognitive change after retirement.

CONCLUSION

Cognitive functioning may decline at an accelerated rate immediately post-retirement, more so in White adults and men than Black adults and women. Lifelong structural inequalities including occupational segregation and other social determinants of cognitive health may obscure the role of retirement in cognitive aging.

Improving Older Adults' Health by Reducing Administrative Burden

Policy Points Administrative burdens, which are the onerous experiences people have when trying to access government benefits and services, reduce older adult's access to health promoting policies. Although considerable attention has been focused on threats to the old-age welfare state, ranging from long-term financing problems to attempts to roll back benefits, administrative barriers to these programs already threaten their effectiveness. Reducing administrative burden is a viable way to improve population health among older adults going forward over the next decade.

Socioeconomic disparities in health outcomes in the United States in the late 2010s: results from four national population-based studies

BACKGROUND

Despite the importance of monitoring health disparities by multiple socioeconomic categories, there have been no recent updates on the prevalence of general health indicators by socioeconomic categories. The present study aims to update the prevalence estimates of health indicators by education and income categories across three age groups (children, young and middle-aged adults, and older adults) in the late 2010s by using four nationally representative data sources. We also examine socioeconomic differences in health by race/ethnicity subgroups.

METHODS

Data were obtained from four nationally representative data sources from the U.S.: The National Health Interview Survey (2015-2018); the National Health and Nutrition Examination Survey, NHANES (2017-2020); the Behavioral Risk Factor Surveillance System (2016-2020); and the Health & Retirement Study (2016). Respondent-rated health and obesity were selected as the health indicators of interest. Socioeconomic factors included percentages of the federal poverty level and years of educational attainment. We conducted logistic regression analyses to calculate adjusted prevalence rates of respondent-rated (or measured, in the case of obesity in NHANES) poor health and obesity by income and education categories after controlling for sociodemographic characteristics. The complex sampling designs were accounted for in all analyses.

RESULTS

Prevalence rates across racial/ethnic groups and age groups demonstrated clear and consistent socioeconomic gradients in respondent-rated poor health, with the highest rates among those in the lowest income and education categories, and decreased rates as income and education levels increased. On the other hand, there were less evident socioeconomic differences in obesity rates across all data sources, racial/ethnic groups, and age groups.

CONCLUSIONS

Our results confirmed earlier, persistent evidence indicating socioeconomic disparities in respondent-rated poor health across all age and race/ethnicity groups by using four nationally representative datasets. In comparison to a decade earlier, socioeconomic disparities in poor health appeared to shrink while they emerged or increased for obesity. The results suggest an urgent need for action to alleviate pervasive health disparities by socioeconomic status. Further research is needed to investigate potentially modifiable factors underlying socioeconomic disparities in health, which may help design targeted health promotion programs.

Projecting years in good health between age 50-69 by education in the Netherlands until 2030 using several health indicators - an application in the context of a changing pension age

Objective

We investigate whether there are changes over time in years in good health people can expect to live above (surplus) or below (deficit) the pension age, by level of attained education, for the past (2006), present (2018) and future (2030) in the Netherlands.

Methods

We used regression analysis to estimate linear trends in prevalence of four health indicators: self-assessed health (SAH), the Organization for Economic Co-operation and Development (OECD) functional limitation indicator, the OECD indicator without hearing and seeing, and the activities-of-daily-living (ADL) disability indicator, for individuals between 50 and 69 years of age, by age category, gender and education using the Dutch National Health Survey (1989–2018). We combined these prevalence estimates with past and projected mortality data to obtain estimates of years lived in good health. We calculated how many years individuals are expected to live in good health above (surplus) or below (deficit) the pension age for the three points in time. The pension ages used were 65 years for 2006, 66 years for 2018 and 67.25 years for 2030.

Results

Both for low educated men and women, our analyses show an increasing deficit of years in good health relative to the pension age for most outcomes, particularly for the SAH and OECD indicator. For high educated we find a decreasing surplus of years lived in good health for all indicators with the exception of SAH. For women, absolute inequalities in the deficit or surplus of years in good health between low and high educated appear to be increasing over time.

Conclusions

Socio-economic inequalities in trends of mortality and the prevalence of ill-health, combined with increasing statutory pension age, impact the low educated more adversely than the high educated. Policies are needed to mitigate the increasing deficit of years in good health relative to the pension age, particularly among the low educated.

Physical work conditions and disparities in later life functioning: Potential pathways

Research in the US on the social determinants of reduced physical functioning at older ages has typically not considered physical work conditions as contributors to disparities. We briefly describe a model of occupational stratification and segregation, review and synthesize the occupational health literature, and outline the physiological pathways through which physical work exposures may be tied to long-term declines in physical functioning. The literature suggests that posture, force, vibration, and repetition are the primary occupational risk factors implicated in the development of musculoskeletal disorders, through either acute injuries or longer-term wear and tear. Personal risk factors and environmental and structural work characteristics can modify this association. In the long-term, these musculoskeletal disorders can become chronic and ultimately lead to functional limitations and disabilities that interfere with one's quality of life and ability to remain independent. We then use data on occupational characteristics from the Occupational Information Network (O*NET) linked to the 2019 American Community Survey (ACS) to examine disparities among sociodemographic groups in exposure to these risk factors. Occupations with high levels of these physical demands are not limited to those traditionally thought of as manual or blue-collar jobs and include many positions in the service sector. We document a steep education gradient with less educated workers experiencing far greater physical demands at work than more educated workers. There are pronounced racial and ethnic differences in these exposures with Hispanic, Black, and Native American workers experiencing higher risks than White and Asian workers. Occupations with high exposures to these physical risk factors provide lower compensation and are less likely to provide employer-sponsored health insurance, making it more difficult for workers to address injuries or conditions that arise from their jobs. In sum, we argue that physical work exposures are likely an important pathway through which disparities in physical functioning arise.

Aging in Different Welfare Contexts: A Comparative Perspective on Later-Life Employment and Health

OBJECTIVE

We adopt a cross-national comparative perspective to assess the labor market experiences of older adults in the years leading up to and beyond the full pension age (FPA) and their association with health in diverse welfare state contexts.

METHOD

We work with a harmonized pooled-country data set of 12 nations to model individuals' employment trajectories during the 10 years surrounding gender- and country-specific FPAs over the same chronological period (2004 to 2014/2015) using sequence analysis. We then analyze these trajectories' relationships with self-rated health and chronic conditions across different welfare state contexts.

RESULTS

We find five types of later-life employment trajectories: early retirement, conventional retirement, predominantly part-time, not in the labor market, and partial retirement. Among other findings, our analyses indicate that early retirement is associated with positive health outcomes in social-democratic and corporatist countries but not in liberal and liberal-corporatist countries. For people in the not in the labor market trajectory, poor self-rated health is more frequent in liberal and southern, and less frequent in corporatist countries.

DISCUSSION

The research findings illustrate the importance of both generous public benefits in old age and later-life employment trajectories for older individuals' health.

Educational differences in the influence of health on early work exit among older workers

Objectives

Previous research has shown that poor physical and mental health are important risk factors for early work exit. We examined potential differences in this association in older workers (50+) across educational levels.

Methods

Coordinated analyses were carried out in longitudinal data sets from four European countries: the Netherlands (Longitudinal Aging Study Amsterdam), Denmark (Danish Longitudinal Study of Ageing), England (English Longitudinal Study of Ageing) and Germany (German Ageing Survey). The effect of poor self-rated health (SRH), functional limitations and depression on different types of early work exit (early retirement, economic inactivity, disability and unemployment) was examined using Cox regression analysis. We examined educational differences in these effects by testing interaction terms.

Results

Poor physical and mental health were more common among the lower educated. Poor SRH, functional limitations, and depression were all associated with a higher risk of early work exit. These health effects were strongest for the disability exit routes (poor SRH: HRs 5.77 to 8.14; functional limitations: HRs 6.65 to 10.42; depression: HRs 3.30 to 5.56). In the Netherlands (functional limitations) and England (functional limitations and SRH), effects were stronger in the lower educated.

Conclusions

The prevalence of health problems, that is, poor SRH, functional limitations and depression, was higher in the lower educated workers. All three health indicators increase the risk of early work exit. In some countries, health effects on early exit were stronger in the lower educated. Thus, lower educated older workers are an important target group for health policy and intervention.

Socioeconomic Vulnerability, Mental Health, and Their Combined Effects on All-Cause Mortality in Koreans, over 45 Years: Analysis of Korean Longitudinal Study of Aging from 2006 to 2014

BACKGROUND

We evaluated the effects of socioeconomic factors and psychosocial factors, both individually and combined, on all-cause mortality risk (mortality risk).

METHODS

We conducted an 8-year (2006-2014) longitudinal analysis of 10,247 individuals who took part in the Korean Longitudinal Study of Aging, a nationwide survey of people aged 45-79 years. Socioeconomic vulnerability (SEV) was assessed with factors such as education, household income, commercial health insurance, and residential area. Mental health (MH) was assessed with factors such as depression, social engagement, and life satisfaction. The covariates were age, gender, marital status, cohabiting, number of chronic diseases, and health behaviors such as regular exercise, smoking, and alcohol intake. We used a Cox proportional hazard analysis to investigate the effects of SEV and MH on mortality risk and also to analyze the superimposed effects of SEV-MH on mortality risk.

RESULTS

After the controlling for the covariates, high SEV and negative MH were found to be strong predictors of all-cause mortality. The highest quartile of SEV (vs. lowest) had a 1.70 times greater mortality risk (hazard ratio [HR], 1.70; 95% confidence interval [CI], 1.24-2.33) and the highest quartile of MH (vs. lowest) had a 2.13 times greater mortality risk (HR, 2.13; 95% CI, 1.72-2.64). Being in the highest quartile for both SEV and MH (vs. lowest) increased mortality risk more than 3 times (HR, 3.11; 95% CI, 2.20-4.40).

CONCLUSION

High SEV and negative MH were independently associated with increased mortality risk, and their superimposed effects were associated with an increased risk of mortality.

Physical Activity and Performance Impact Long-term Quality of Life in Older Adults at Risk for Major Mobility Disability

INTRODUCTION

Older adults are a rapidly growing segment of the U.S.

POPULATION

Mobility problems that lead to further disability can be addressed through physical activity interventions. Quality of life outcome results are reported from a large trial of physical activity for sedentary older adults at risk for mobility disability.

METHODS

Data were from the Lifestyle Interventions and Independence for Elders study. This multisite RCT compared physical activity to health education among 1,635 randomly assigned sedentary older adults at risk for mobility disability in 2010-2011. Measures included demographics; comorbidity; a timed 400-meter walk; the Short Physical Performance Battery; and the Quality of Well-Being Scale (0-1.0 scale). Baseline and long-term follow-up (2.6 years) health-related quality of life data were collected as a secondary outcome. Multivariate linear regression modeling was used to examine covariates of health-related quality of life over time in 2017.

RESULTS

The sample had an overall mean Quality of Well-Being score of 0.613. Both groups declined in quality of life over time, but assignment to the physical activity intervention resulted in a slower decline in health-related quality of life scores (p=0.03). Intervention attendance was associated with higher health-related quality of life for both groups. Baseline characteristics including younger age, fewer comorbid conditions, non-white ethnicity, and faster 400-meter walk times were also associated with higher health-related quality of life over time.

CONCLUSIONS

Declining mobility measured by physical performance is associated with lower quality of life in sedentary older adults. Physical activity interventions can slow the decline in quality of life, and targeting specific subgroups may enhance the effects of such interventions.

Can we determine whether physical limitations are more prevalent in the US than in countries with comparable life expectancy?

We evaluate the variability in estimates of self-reported physical limitations by age across four nationally representative surveys in the US. We consider its implications for determining whether, as previous literature suggests, the US estimates reveal limitations at an earlier age than in three countries with similar life expectancy: England, Taiwan, and Costa Rica. Based on cross-sectional data from seven population-based surveys, we use local mean smoothing to plot self-reported limitations by age for each of four physical tasks for each survey, stratified by sex. We find substantial variation in the estimates in the US across four nationally-representative surveys. For example, one US survey suggests that American women experience a walking limitation 15 years earlier than their Costa Rican counterparts, while another US survey implies that Americans have a 4-year advantage. Differences in mode of survey may account for higher prevalence of limitations in the one survey that used a self-administered mail-in questionnaire than in the other surveys that used in-person or telephone interviews. Yet, even among US surveys that used the same mode, there is still so much variability in estimates that we cannot conclude whether Americans have better or worse function than their counterparts in the other countries. Seemingly minor differences in question wording and response categories may account for the remaining inconsistency. If minor differences in question wording can result in such extensive variation in the estimates within a given population, then lack of comparability is likely to be an even greater problem when examining results across countries that do not share the same language or culture. Despite the potential utility of self-reported physical function within a survey sample, our findings imply that absolute estimates of population-level prevalence of self-reported physical limitations are unlikely to be strictly comparable across countries—or even across surveys within the same population.

•

Self-reported physical limitation estimates vary widely across US national surveys.

•

Thus, we cannot determine whether Americans have worse function than others.

•

Differences in mode of survey may account for some of the variability.

•

Minor differences in question wording and response categories may also play a role.

Do socioeconomic inequalities in pain, psychological distress and oral health increase or decrease over the life course? Evidence from Sweden over 43 years of follow-up

BACKGROUND

Inequalities over the life course may increase due to accumulation of disadvantage or may decrease because ageing can work as a leveller. We report how absolute and relative socioeconomic inequalities in musculoskeletal pain, oral health and psychological distress evolve with ageing.

METHODS

Data were combined from two nationally representative Swedish panel studies: the Swedish Level-of-Living Survey and the Swedish Panel Study of Living Conditions of the Oldest Old. Individuals were followed up to 43 years in six waves (1968, 1974, 1981, 1991/1992, 2000/2002, 2010/2011) from five cohorts: 1906-1915 (n=899), 1925-1934 (n=906), 1944-1953 (n=1154), 1957-1966 (n=923) and 1970-1981 (n=1199). The participants were 15-62 years at baseline. Three self-reported outcomes were measured as dichotomous variables: teeth not in good conditions, psychological distress and musculoskeletal pain. The fixed-income groups were: (A) never poor and (B) poor at least once in life. The relationship between ageing and the outcomes was smoothed with locally weighted ordinary least squares, and the relative and absolute gaps were calculated with Poisson regression using generalised estimating equations.

RESULTS

All outcomes were associated with ageing, birth cohort, sex and being poor at least once in live. Absolute inequalities increased up to the age of 45-64 years, and then they decreased. Relative inequalities were large already in individuals aged 15-25 years, showing a declining trend over the life course. Selective mortality did not change the results. The socioeconomic gap was larger for current poverty than for being poor at least once in life.

CONCLUSION

Inequalities persist into very old age, though they are more salient in midlife for all three outcomes observed.

How participants report their health status: cognitive interviews of self-rated health across race/ethnicity, gender, age, and educational attainment

BACKGROUND

Self-rated health (SRH) is widely used to measure subjective health. Yet it is unclear what underlies health ratings, with implications for understanding the validity of SRH overall and across sociodemographic characteristics. We analyze participants' explanations of how they formulated their SRH answer in addition to which health factors they considered and examine group differences in these processes.

METHODS

Cognitive interviews were conducted with 64 participants in a convenience quota sample crossing dimensions of race/ethnicity (white, Latino, black, American Indian), gender, age, and education. Participants rated their health then described their thoughts when answering SRH. We coded participants' answers in an inductive, iterative, and systematic process from interview transcripts, developing analytic categories (i.e., themes) and subdimensions within. We examined whether the presence of each dimension of an analytic category varied across sociodemographic groups.

RESULTS

Our qualitative analysis led to the identification and classification of various subdimensions of the following analytic categories: types of health factors mentioned, valence of health factors, temporality of health factors, conditional health statements, and descriptions and definitions of health. We found differences across groups in some types of health factors mentioned-corresponding, conflicting, or novel with respect to prior research. Furthermore, we also documented various processes through which respondents integrate seemingly disparate health factors to formulate an answer through valence and conditional health statements. Finally, we found some evidence of sociodemographic group differences with respect to types of health factors mentioned, valence of health factors, and conditional health statements, highlighting avenues for future research.

CONCLUSION

This study provides a description of how participants rate their general health status and highlights potential differences in these processes across sociodemographic groups, helping to provide a more comprehensive understanding of how SRH functions as a measure of health.

Predictors of Self-Rated Health: Does Education Play a Role Above and Beyond Age?

Objectives

Previous studies have demonstrated that while health factors lose importance for the individual conceptualization of self-rated health (SRH) with advancing age, subjective well-being (SWB) factors gain in importance. The present study examined whether this age-related pattern differs between educational groups.

Method

Longitudinal data of adults aged 40 years and older of the German Ageing Survey was used (N = 6,812). The role of education in age-related changes in the predictive value of different health and SWB facets for SRH was investigated with a cross-lagged panel regression model.

Results

Physical conditions were a stronger predictor in lower than in higher educated individuals while the association did not change with age. In contrast, positive affect and life satisfaction only gained in importance with advancing age for higher educated individuals. Negative affect was an equally strong predictor independent of education, and loneliness had a stronger association with SRH in people with lower education compared to those with high education while the associations did not change with age.

Discussion

The findings highlight the importance of considering the multidimensionality of SWB and the educational background of individuals for the study of SRH and indicate possible limits to adjustment to age-related declines in health.

An inquiry into self-identification with retirement

The aim of this qualitative study was to explore patterns in self-identification with being retired using deductive thematic analysis informed by the life course perspective. For this study, a set of women who self-identified as retired (n = 60) were asked to describe their current work status, major career interruptions, and factors that marked their retirement. This study provides important insights into the heterogeneity in women's retirement including a subset of individuals who self-identified as retired, not based on their own work force transitions but on that of their spouse or peers. Findings highlight the importance of recognizing that the construction of retirement identity can be context driven, varied, and subjective.

An ageing world and the challenges for a model of sustainable social change

Purpose

– Although the world is rapidly ageing, the alarming explosion of youth unemployment seems to have removed the workforce ageing issue as a priority from the policy agenda. The purpose of this paper is to test and investigate the main needs and willingness to work among the older population, as well as the main advantages for organizations employing older workers.

Design/methodology/approach

– The main research objectives were: first, to explore the effect of demographic and socio-economic predictors on an older person’s intention to work; and second, to focus on the main advantages that should induce organizations to retain older workers in their workplace. The paper is based on a survey and an interdisciplinary review of the literature.

Findings

– The study indicated that educational level led to improved active behaviours in the labour market. In other words, people who obtained a higher level of education showed a greater likelihood to desire a prolongation of working life, while lower educational attainment may have lessened the willingness and capacity of older people to remain in the workforce. The main benefits for organizations with older workers are highlighted.

Research limitations/implications

– The survey has a number of limitations: the sample is small and was completed with reference to a single country, making it difficult to generalize results beyond this country study; the questionnaire relied solely on a few areas, while it would be better to gather additional information; the survey only targeted retired people, while it would have been interesting to also collect answers from workers nearing retirement. The association between individuals’ educational levels and their intention to work in later life suggests that continued development of educational programmes for workers could favour greater retention in the workplace.

Practical implications

– As the ageing population is an increasing phenomenon, the participation of older people in the labour force and lifelong learning should become commonplace in the perspective of a more equitable society. The main challenge is to rethink retirement, by abolishing the mandatory retirement age and by providing more flexible work options.

Social implications

– Changes in national system and corporate strategies are required to meet the economic challenges of ageing populations.

Originality/value

– This study advances research on age management because it provided evidence that educational background plays a fundamental role in determining the willingness to return to work. In addition, the paper proposes a new integrated approach of sustainable social change.

Work Disability among Women: The Role of Divorce in a Retrospective Cohort Study

We assess how divorce through midlife affects the subsequent probability of work-limiting health among U.S. women. Using retrospective marital and work disability histories from the Survey of Income and Program Participation matched to Social Security earnings records, we identify women whose first marriage dissolved between 1975 and 1984 (n = 1,214) and women who remain continuously married (n = 3,394). Probit and propensity score matching models examine the cumulative probability of a work disability over a 20-year follow-up period. We find that divorce is associated with a significantly higher cumulative probability of a work disability, controlling for a range of factors. This association is strongest among divorced women who do not remarry. No consistent relationships are observed among divorced women who remarry and remained married. We find that economic hardship, work history, and selection into divorce influence, but do not substantially alter, the lasting impact of divorce on work-limiting health.
