Inequalities in life and death : Income and mortality in an ageing population
- 2019
-
Doctoral thesis (other academic/artistic)abstract
- Income serves as an indicator of success relative to others, and provides individuals with resources that strengthen their capability to face challenges and benefit from opportunities. Out of all social determinants of health, income is one of the strongest predictors of health outcomes. The positive association between income and health in the working-age population is well established; those with higher income tend to have better health. Less is known about the association between income and health among older persons. Several studies have observed that in old age, health inequalities decrease and the relationship between income and health weakens. However, at what point in the ageing process the association starts to weaken, and to what extent, is debated.The ageing process highlights the need for several theoretical considerations in studies on income and health. Societies are stratified by age, as manifested through transitions in and out of education, work, and retirement. Moreover, the individual experience of the ageing process involves biological processes of decline. Many health problems, and particularly death, are uncommon events during most of adulthood. In old age, however, health decline becomes a normative experience, and in Sweden, more than 90 percent of all deaths occur among people aged 65 or older. The characteristics and magnitude of age-related changes in the association between income and mortality constitute one of the prime concerns in this thesis. I have used two contending perspectives to understand the empirical results: the cumulative (dis)advantage theory and the age-as-leveler hypothesis.In this thesis, I have investigated the association between income and mortality across ages, with a focus on later life. More specifically, I studied the shape and magnitude of the income-mortality association across the life course. Furthermore, I tested two potential mechanisms that may shape this association in old age: health decline and mortality selection. Overall, this thesis shows to what extent and in what ways the association between income and mortality is maintained in old ageThis thesis includes four empirical studies. Study I, II, and IV are based on data from Swedish national registers (n = 801,017 – 5,011,414). Study III used survey data (LNU and SWEOLD) linked with data from administrative registries (n = 2619). The results from Study I showed that the income-mortality association was curvilinear with diminishing returns of income in both mid-life and late-life. Study II showed that relative mortality inequalities in income decreased with age and absolute mortality inequalities in income increased with age up to age 85-90, after which the mortality inequalities decreased. The results from Study III showed that health decline partly explained the weakened income-mortality association among the oldest old. Finally, Study IV showed that selective mortality had a substantial impact on poverty rates in old age; poverty rates were consistently and substantially lower for those who survived than those who died. Furthermore, selective mortality had the largest influence on the surviving population when mortality rates were at their highest.

- Objective We investigate recent trends in income inequalities in mortality and the shape of the association in Sweden. We consider all-cause, preventable and non-preventable mortality for three age groups (30–64, 65–79 and 80+ years).Design and setting Repeated cross-sectional design using Swedish total population register data.Participants All persons aged 30 years and older living in Sweden 1995–1996, 2005–2006 and 2016–2017 (n=8 084 620).Methods Rate differences and rate ratios for all-cause, preventable and non-preventable mortality were calculated per income decile and age group.Results From 1995 to 2017, relative inequalities in mortality by income increased in Sweden in the age groups 30–64 years and 65–79 years. Absolute inequalities increased in the age group 65–79 years. Among persons aged 80+ years, inequalities were small. The shape of the income–mortality association was curvilinear in the age group 30–64 years; the gradient was stronger below the fourth percentile. In the age group 65–79 years, the shape shifted from linear in 1995–1996 to a more curvilinear shape in 2016–2017. In the oldest age group (80+ years), varied shapes were observed. Inequalities were more pronounced in preventable mortality compared with non-preventable mortality. Income inequalities in preventable and non-preventable mortality increased at similar rates between 1995 and 2017.Conclusions The continued increase of relative (ages 30–79 years) and absolute (ages 65–79 years) mortality inequalities in Sweden should be a primary concern for public health policy. The uniform increase of inequalities in preventable and non-preventable mortality suggests that a more complex explanatory model than only social causation is responsible for increased health inequalities.

Can Sex Differences in Old Age Disabilities be Attributed to Socioeconomic Conditions? Evidence from a Mapping Review of the Literature
- 2023

Journal article (peer-reviewed)abstract
- Old age disabilities are more common among women than men, and adverse socioeconomic conditions are associated with a higher prevalence of disabilities among older adults. The goal of this study was to complete a mapping review of the available evidence assessing the extent to which the observed sex differences in older adults´ disabilities can be attributed to sex differences in socioeconomic status. We searched three databases for articles published between 2009 and 2019, and after screening and looking at eligibility criteria, 6 articles were included in the review. For those studies that did not directly analyse the contribution of socioeconomic conditions, we used the´difference method´ to estimate the proportion of the sex gap in disabilities among older adults that could be attributed to socioeconomic conditions. Our review demonstrated that women generally have a higher prevalence of disabilities than men. In several studies, these differences could be partly attributed to sex differences in the distribution of socioeconomic conditions. We also find great elasticity in the magnitude of both the sex gap in disabilities and in the proportion that could be attributed to differences in socioeconomic conditions.

Longitudinal associations between sensory and cognitive functioning in adults 60 years or older in Sweden and Denmark
- 2024
-
In: Archives of gerontology and geriatrics (Print). - : Elsevier. - 0167-4943 .- 1872-6976. ; 121
-
Journal article (peer-reviewed)abstract
- BACKGROUND: The objective of this study is to explore the bidirectional, longitudinal associations between self-reported sensory functions (hearing/vision) and cognitive functioning among older adults in Sweden and Denmark during the period 2004-2017.METHODS: The study is based on data from The Survey of Health, Ageing and Retirement in Europe and consists of 3164 persons aged 60 to 93 years. Within-person associations between sensory and cognitive functions were estimated using random intercept cross-lagged panel models.RESULTS: The results indicated that cognitive and sensory functions were associated within their respective domains over time. The results on the bidirectional associations between sensory functions and cognition over time showed weak and statistically non-significant estimates.CONCLUSION: Our study showed no clear evidence for cross-lagged effects between sensory functions and cognitive functioning. Important to note, however, is that using longitudinal data to estimate change within persons is a demanding statistical test and various factors may have contributed to the absence of conclusive evidence in our study. We discuss several of these factors.

A social exclusion perspective on loneliness in older adults in the Nordic countries
- 2022

In: European Journal of Ageing. - : Springer Science and Business Media LLC. - 1613-9372 .- 1613-9380. ; 19:2, s. 175-188
-
Journal article (peer-reviewed)abstract
- Several factors associated with loneliness are also considered indicators of social exclusion. While loneliness has been proposed as an outcome of social exclusion, there is limited empirical evidence of a link. This study examines the associations between social exclusion indicators and loneliness in older adults (60+ years) in four Nordic countries. Data from four waves of the European Social Survey were pooled, providing a total of 7755 respondents (Denmark n = 1647; Finland n = 2501, Norway n = 1540; Sweden n = 2067). Measures of loneliness, demographic characteristics, health, and eight indicators of social exclusion were selected from the survey for analysis. Country-specific and total sample hierarchical logistic regression models of loneliness were developed. Significant model improvement occurred for all models after social exclusion indicators were added to models containing only demographic and health variables. Country models explained between 15.1 (Finland) and 21.5% (Sweden) of the variance in loneliness. Lower frequency of social contacts and living alone compared to in a two-person household was associated with a higher probability of loneliness in all countries, while other indicators were associated with loneliness in specific countries: lower neighbourhood safety (Sweden and Denmark); income concern (Sweden and Finland); and no emotional support (Denmark, Finland, and Sweden). A robust relationship was apparent between indicators of social exclusion and loneliness with the direction of associations being highly consistent across countries, even if their strength and statistical significance varied. Social exclusion has considerable potential for understanding and addressing risk factors for loneliness.

Journal article (peer-reviewed)abstract
- As the population of Europe grows older, one crucial issue is how the incidence and prevalence of disabilities are developing over time in the older population. In this study, we compare cohort-specific disability trajectories in old age across subsequent birth cohorts in Europe, during the period 2004–2017.We used data from seven waves of data from the Survey of Health, Ageing and Retirement in Europe (SHARE). Mixed effects logistic regression models were used to model trajectories of accumulation of ADL limitations for subsequent birth cohorts of older women and men in different European regions. The results showed that there were sex differences in ADL and IADL limitations in all regions for most cohorts. Women reported more limitations than men, particularly in Eastern and Southern rather than Northern and Western Europe. Among men in Eastern, Northern and Western Europe, later born cohorts reported more disabilities than did earlier born birth cohorts at the same ages. Similar patterns were observed for women in Northern and Western Europe. In contrast, the risk of disabilities was lower in later born cohorts than in earlier born birth cohorts among women in Eastern Europe. Overall, results from this study suggest that disability trajectories in different cohorts of men and women were by and large similar across Europe. The trajectories varied more depending on sex, age and region than depending on cohort.

One generation apart : Individual income and life expectancy in two Swedish cohorts born before and after the expansion of the welfare state
- 2024
-
In: Scandinavian Journal of Public Health. - 1403-4948 .- 1651-1905.
-
Journal article (peer-reviewed)abstract
- Aims: Social inequalities in mortality persist or even increase in high-income countries. Most evidence is based on a period approach to measuring mortality – that is, data from individuals born decades apart. A cohort approach, however, provides complementary insights using data from individuals who grow up and age under similar social and institutional arrangements. This study compares income inequalities in cohort life expectancy in two Swedish cohorts, one born before and one born after the expansion of the welfare state. Methods: Data on individuals born in Sweden in 1922–1926 and 1951–1955 were obtained from total population registries. These data were linked to individual disposable income from 1970 and 1999 and mortality between 50 and 61 years of age in 1972–1987 and 2001–2016, respectively. We calculated cohort temporary life expectancies in the two cohorts by income and gender. Results: Life expectancy, income, and income inequalities in life expectancy increased between the two cohorts, for both men and women. Women born in 1922–1926 had modest income differences in life expectancy, but pronounced differences emerged in the cohort born in 1951–1955. Men with low incomes born in 1951–1955 had roughly similar life expectancy as those with low incomes born in 1922–1926. Conclusions: Compared with a period approach to life expectancy trends, the cohort approach highlights the stagnation of mortality at the lowest income groups for men and the rapid emergence of a mortality gradient for women. Future research on health inequalities in welfare states should consider underlying factors both from a cohort and period perspective.

Gender differences in access to community-based care : a longitudinal analysis of widowhood and living arrangements
- 2022
-
In: European Journal of Ageing. - : Springer Science and Business Media LLC. - 1613-9372 .- 1613-9380. ; 19:4, s. 1339-1350

Journal article (peer-reviewed)abstract
- Persistent inequalities in access to community-based support limit opportunities for independent living for older people with care needs in Europe. Our study focuses on investigating how gender, widowhood and living arrangement associate with the probability of receiving home and community-based care, while accounting for the shorter-term associations of transitions into widowhood (bereavement) and living alone, as well as the longer-term associations of being widowed and living alone. We use comparative, longitudinal data from the Survey of Health, Ageing and Retirement in Europe (collected between 2004 and 2015 in 15 countries) specifying sex-disaggregated random-effects within-between models, which allow us to examine both cross-sectional and longitudinal associations among widowhood, living arrangements and community-based care use. We find widowhood and living alone are independently associated with care use for both older women and men, while bereavement is associated with higher probability of care use only for women. Socio-economic status was associated with care use for older women, but not for men in our sample. The gender-specific associations we identify have important implications for fairness in European long-term care systems. They can inform improved care targeting towards individuals with limited informal care resources (e.g. bereaved older men) and lower socio-economic status, who are particularly vulnerable to experiencing unmet care needs. Gender differences are attenuated in countries that support formal care provision, suggesting gender equity can be promoted by decoupling access to care from household and family circumstances.

The Association between Education and Cognitive Performance Varies at Different Levels of Cognitive Performance : A Quantile Regression Approach
- 2024
-
In: Gerontology. - 0304-324X .- 1423-0003. ; 70:3, s. 318-326
-
Journal article (peer-reviewed)abstract
- Introduction: Educational differences in cognitive performance among older adults are well documented. Studies that explore this association typically estimate a single average effect of education on cognitive performance. We argue that the processes that contribute to the association between education and cognitive performance are unlikely to have equal effects at all levels of cognitive performance. In this study, we employ an analytical approach that enables us to go beyond averages to examine the association between education and five measures of global and domain-specific cognitive performance across the outcome distributions. Methods: This cross-sectional study included 1,780 older adults aged 58–68 years from the Longitudinal Aging Study Amsterdam. Conditional quantile regression was used to examine variation across the outcome distribution. Cognitive outcomes included Mini-Mental State Examination (MMSE) score, crystallized intelligence, information processing speed, episodic memory, and a composite score of global cognitive performance. Results: The results showed that the associations between education and different cognitive measures varied across the outcome distributions. Specifically, we found that education had a stronger association with crystallized intelligence, MMSE, and a composite cognitive performance measure in the lower tail of performance distributions. The associations between education and information processing speed and episodic memory were uniform across the outcome distributions. Conclusion: Larger associations between education and some domains of cognitive performance in the lower tail of the performance distributions imply that inequalities are primarily generated among individuals with lower performance rather than among average and high performers. Additionally, the varying associations across some of the outcome distributions indicate that estimating a single average effect through standard regression methods may overlook variations in cognitive performance between educational groups. Future studies should consider heterogeneity across the outcome distribution.

Cohort Trajectories by Age and Gender for Informal Caregiving in Europe Adjusted for Sociodemographic Changes, 2004 and 2015
- 2023
-
In: The journals of gerontology. Series B, Psychological sciences and social sciences. - : Oxford University Press (OUP). - 1079-5014 .- 1758-5368. ; 78:8, s. 1412-1422
-
Journal article (peer-reviewed)abstract
- Objectives We present a dynamic view of gender patterns in informal caregiving across Europe in a context of sociodemographic transformations. We aim to answer the following research questions: (a) has the gender gap in informal caregiving changed; (b) if so, is this due to changes among women and/or men; and (c) has the gender care gap changed differently across care regimes? Methods Multilevel growth curve models are applied to gendered trajectories of informal caregiving of a panel sample of 50+ Europeans, grouped into 5-year cohorts and followed across 5 waves of the Survey of Health, Ageing and Retirement in Europe survey, stratified by sex and adjusted for several covariates. Results For men in cohorts born more recently, there is a decrease in the prevalence of informal care outside the household, whereas cohort trajectories for women are mostly stable. Prevalence of care inside the household has increased for later-born cohorts for all without discernible changes to the gender care gap. Gender care gaps overall widened among later-born cohorts in the Continental cluster, whereas they remained constant in Southern Europe, and narrowed in the Nordic cluster. Discussion We discuss the cohort effects found in the context of gender differences in employment and care around retirement age, as well as possible demographic explanations for these. The shift from care outside to inside the household, where it mostly consists of spousal care, may require different policies to support carers, whose age profile and possible care burden seem to be increasing.
