Early-Life Socioeconomic Disadvantage and Health in Late Middle-Age: Importance of Heterogeneous Income Trajectories.

This paper aims to investigate heterogeneous income changes and whether the income trajectories moderate effects of early socioeconomic disadvantage on health in late middle age. The sample was restricted to 9,056 middle-aged adults from the Health and Retirement Study (1998-2010). Through a latent class growth analysis, six patterns of income changes were identified: constantly low, constantly moderate, constantly high & increasing, high to low, moderate to high, and high to moderate. The Constantly low group more frequently displayed depressive symptoms if exposed to early socioeconomic disadvantage and Constantly low income mobility. Individuals who experienced early socioeconomic disadvantage and a downward income mobility in middle age tended to have multiple chronic conditions while there was no moderating effect of income changes for mobility functional limitations. These findings suggest that not all health outcomes are programmed in early life: Disadvantage can be somewhat alleviated through stable and better later-life economic status.

Multimorbidity and Employment Outcomes Among Middle-Aged US Cancer Survivors.

OBJECTIVE: The objective of this study was to evaluate the relationship between multimorbidity and subsequent 2-year employment outcomes among middle-aged United States (US) cancer survivors. In addition, we examined whether the relationship differed by survivor characteristics. METHODS: Data of 633 cancer survivors (ages 51 to 64) from the 2014 Health and Retirement Study were used to identify multimorbidity profiles and evaluate associations between multimorbidity and prolonged unemployment during follow-up. RESULTS: Approximately 64% of cancer survivors met the criteria for multimorbidity. Latent class analysis revealed three distinct multimorbidity profiles distinguished by the presence or absence of psychiatric disorders. We observed a significant association between high psychiatric multimorbidity and prolonged unemployment after 2-year follow-up (relative risk = 2.78, 95% Confidence Interval = 1.28 to 6.00), with the effect more pronounced among low-income survivors. CONCLUSIONS: Psychiatric multimorbidity was associated with prolonged unemployment among middle-aged cancer survivors, particularly among low-income survivors.

Multiple pathways linking early socioeconomic circumstances and depressive symptoms in late Middle age in the U.S.

Objectives: A growing number of life course studies are examining the influence of earlier life experiences on morbidity, disability, and mortality in mid-old age.Method: Drawing from the social pathway model, this study expands the life course literature by utilizing data collected over 35 years from the National Longitudinal Survey of Youth, 1979 Cohort, spanning four life course phases (childhood, young adulthood, middle adulthood, and late-middle adulthood). Through structural equation analyses with a phantom model, we estimated depressive symptoms in late middle age as a result of pathway effects starting with childhood socio-economic status (SES) which effect young adulthood and middle adulthood. The multi-pathway life course model includes three potential mediators of middle adulthood: health risk behaviors, social activity, and negative life events.Results: We found limited support for a direct effect of childhood SES disadvantage on depressive symptoms in middle age. Instead, much of the effects of childhood SES on later-year depressive symptoms appear to be mediated by SES in young adulthood. Further, the long-term pathway is mediated through the influence of health risk behaviors and negative life events in middle adulthood.Conclusion: Our findings do not propose this chain is permanent and irreversible; rather, this study highlights the possibility that interventions focused on promoting health behaviors and improving living conditions for people from socioeconomically disadvantaged backgrounds could help reduce the instance of depression in middle age and health outcomes along the life course could be improved.

Life Course Pathway to Later-Year Depressive Symptoms: Multiple Mediation of Socio-Economic Status and Coping Resources by Gender.

Drawing on a life course and stress process perspective, this study examined the pathway from childhood SES to later year depressive symptoms, focusing on multiple life course SES and coping resources in old age. Data came from the 2006 and 2015 waves of the Korea Welfare Panel Study (KOWEPS). We selected respondents aged 51-55 in 2006 who were followed up when they were between 60 to 64 years of age in 2015. We merged the middle aged data in 2006 with the 2015 data when the respondents were 60-64 years of age (N = 687). Phantom modeling was used to examine a multiple mediation pathway and multi-group analyses were conducted to examine the gender differences in the pathway.For older men, satisfaction with social/leisure activities was a significant coping resource, while, for older women, satisfaction with family relations was important.

Long-Term Employment Outcomes among Female Cancer Survivors.

Advances in early detection and treatment have led to a growing population of female cancer survivors, many of whom are of working age. We examined the relationship between cancer and long-term (>5 years) employment outcomes in a nationally representative sample of working-age women in the United States. Data from nine waves of the Health and Retirement Study were used to examine employment status and weekly hours worked among cancer survivors (n = 483) and women without cancer (n = 6605). We used random slope regression models to estimate the impact of cancer and occupation type on employment outcomes. There was no difference in employment status between cancer survivors and women without cancer at baseline; however, during follow-up, cancer survivors were more likely to be employed than women without cancer (odds ratio (OR) = 1.33, 95% confidence interval (CI): 1.11-1.58). Among 6-10-year survivors, professional workers were less likely (OR = 0.40, 95% CI: 0.21-0.74) to be employed than manual workers. Among >10-year survivors, professional workers averaged fewer weekly hours worked (-2.4 h, 95% CI: -4.4--0.47) than manual workers. The impact of cancer on long-term employment outcomes may differ by occupation type. Identifying the occupation-specific mechanisms associated with the return to work will be critical to developing targeted strategies to promote employment in the growing female cancer survivor population.

Influence of senior housing types on cognitive decline and nursing home admission among lower-income older adults.

Objectives: Focusing on unique ageing populations in subsidized senior housing for lower-income older adults, this study contributes to literature on housing and aging; provides initial understanding of existing housing types; and explores the extent to which living in different housing types may influence changes in cognitive function and likelihood of nursing home admission.Method: Data came from seven waves (2002-2014) of the Health and Retirement Study. A latent-class clustering approach was used to identify senior-housing types among lower-income older people;Results: We identified four discernible housing types among lower-income older adults: (1) High physical & Low service, (2) Low physical & Low service, (3) High physical & High service, and (4) Medium physical & High service. Individuals in Medium physical & High service and High physical & Low service types were likely to have higher cognitive-function levels at baseline (B = 0.58, p < .001; 0.58, p < .001) and slower rates of decline over time (B = 0.42, p < .001; B = 0.32, p < .01). Older adults in High physical & High service are significantly less likely to be admitted to a nursing home (OR = 0.55, p < .00).Conclusion: The mismatch between health needs and lack of service and support suggests that current residents in each housing type relocate, based on knowledge of subsidized housing or availability. Future studies should examine possible mismatches between health needs and housing environment.

Nature of Retirement and Loneliness: The Moderating Roles of Social Support.

Drawing from the social convoy model, this study investigates whether the nature of retirement (voluntary or involuntary) influences loneliness among retirees, and how different social support types may affect this association. Data come from the 2014 Health and Retirement Study (N = 2,055). Five social support types were identified: weak, ambivalent, strong positive, children strain, and family strain. Involuntary retirement was associated with a higher level of loneliness; however, involuntarily retired individuals with strong positive social support had a relatively lower level of loneliness. Findings from this study suggest that social support may alleviate the negative impacts of involuntary retirement. Our research provides a theoretical basis for developing a practical program to reduce the negative impacts of involuntary retirement on well-being.

Person-Environment Fit Approach to Trajectories of Cognitive Function Among Older Adults Who Live Alone: Intersection of Life-Course SES Disadvantage and Senior Housing.

OBJECTIVES: Drawing from life course and environmental perspectives, we examined the trajectory of cognitive function and how senior housing moderates the effects of life-course socioeconomic status (SES) disadvantage among older people living alone over time. METHOD: Six waves of the Health and Retirement Study (HRS) were used with multilevel growth modeling to analyze developmental patterns of cognitive function over time and how various forms of life-course SES disadvantage affect cognitive function depending on senior housing residency status. RESULTS: At baseline, we found a positive role of senior housing in four subgroups: SES disadvantage in childhood only, unstable mobility pattern (disadvantage in childhood and old age only), downward mobility (no disadvantage in childhood, but in later two life stages), and cumulative disadvantage (all three life stages). Over time, the positive role of senior housing for the unstable and the most vulnerable group persisted. DISCUSSION: Our findings provide a much-needed practical and theoretical underpinning for environmental policy-making efforts regarding vulnerable elders who live alone.

The Effect of California's Paid Family Leave Program on Employment Among Middle-Aged Female Caregivers.

BACKGROUND AND OBJECTIVES: This study examined the effect of a Paid Family Leave program in California (CA-PFL) on employment among middle-aged female caregivers. We also examined differences in the relationship between the availability of paid family leave (PFL) and employment in socioeconomic subgroups of midlife women. RESEARCH DESIGN AND METHODS: Data came from multiple years (2000‒2014) of the Current Population Survey (CPS) (N = 68,773 individuals). Applying a Difference in Differences (DiD) approach to removing potential selection biases related to program participation, we used a logistic regression to estimate the effects of PFL. RESULTS: There was a significant increase in the likelihood of working based on CA-PFL. This positive effect, however, was found only among the early middle-aged, the near-poor, and those had the highest level of education. DISCUSSION AND IMPLICATIONS: Among the late middle-aged, caregiving burden may not affect decisions on whether to exit the labor market, and PFL may not significantly mitigate the well-known negative effects of intense and multiple caregiving roles (parents, spouse, and/or children with disabilities). Future studies should examine PFL effects and their correlates such as age-cohorts, caregiving intensity, and retirement patterns. The unexpected null findings of CA-PFL's effect on employment outcomes for the poor and those with low education levels suggests these vulnerable groups might not be able to fully benefit from the originally intended goal of the policy, instead being left more vulnerable compared to the near poor. Such a possibility increases the importance of focused research and policymaking attention for this group.

Health Insurance and Poverty in Trajectories of Out-of-Pocket Expenditure among Low-Income Middle-Aged Adults.

OBJECTIVE: To assess the effects of longitudinal patterns of health insurance and poverty on out-of-pocket expenditures among low-income late middle-aged adults. DATA SOURCES/STUDY SETTING: Six waves (2002-2012) of the Health and Retirement Study, in combination with RAND Center for the Study of Aging data, were used. STUDY DESIGN: A random coefficient regression analysis was conducted in a multilevel growth curve framework to estimate the impact of health insurance and poverty on out-of-pocket expenditures. PRINCIPAL FINDINGS: At baseline, individuals with private insurance or unstable coverage were more likely to have out-of-pocket expenditures and financial burdens than public insurance holders. Over time, the poor who had no insurance, unstable coverage, or insurance type change had higher out-of-pocket expenditures; private coverage holders had higher odds of financial burden. CONCLUSIONS: Unstable insurance coverage had a discernible effect on the long-term, out-of-pocket expenditures among low-income adults. Findings have an important policy implication to protect poor late middle-aged population; as this population enters old age, the high financial burden it faces may exacerbate persistent socioeconomic health disparity among older people with unstable insurance coverage.

Heterogeneous Trajectories of Depressive Symptoms in Late Middle Age: Critical Period, Accumulation, and Social Mobility Life Course Perspectives.

OBJECTIVE: This study investigated patterns of depressive symptoms and whether socioeconomic status (SES) across the life course affects these trajectories using the critical period, accumulation, and social mobility models. METHOD: This study uses data from 8,532 adults, age 51 to 64, collected over 12 years from the Health and Retirement Study (observations = 25,887). A latent class analysis was performed to examine distinct depressive symptom trajectories; life course models were studied with multinomial logistic regression. RESULTS: Four heterogeneous latent classes were identified for depression: Declining, Low, Increasing, and High and Increasing. The High and Increasing group was associated with a disadvantaged childhood SES, accumulated exposure to socioeconomic risks, and persistent SES disadvantage supporting the three life course models. DISCUSSION: There was evidence of distinct profiles of depressive symptoms in late middle age and of interrelated life course mechanisms underlying the influences of childhood SES on later life depression.

The Role of Senior Housing in Hospitalizations Among Vulnerable Older Adults With Multiple Chronic Conditions: A Longitudinal Perspective.

Background and Objectives: This study focuses on vulnerable elders (i.e., those with moderate or low incomes who live alone) and examines to what extent a senior housing environment moderates the effects of multiple chronic conditions (MCCs) on hospitalization over time. Research Design and Methods: Data came from six waves (2002-2012) of the Health Retirement Study (N = 1,401 individuals, 3,705 observations). Mixed-effect multinomial logistic regression modeling estimated the effects of senior housing on changes in hospitalization. Results: Vulnerable elders with MCCs were more likely to be hospitalized at both moderate and heavy levels at baseline. Consistent with the environment docility hypothesis, findings show that older individuals with MCCs who live in a senior housing environment have fewer hospitalizations over time. Discussions and Implications: As one of the first efforts to build empirical knowledge on health care use among vulnerable elders in senior housing, our findings underscore the importance of continued research into these environments as a possible alternative to existing models.

Socioeconomic Disparity in Later-Year Group Trajectories of Depressive Symptoms: Role of Health and Social Engagement Change.

This study explored heterogeneous change patterns of South Korean older adults' depressive symptoms by poverty status, focusing on health status and social engagement changes. We used data from four waves (2006-2012) of the Korean Longitudinal Study of Aging (KLoSA). Our sample contained 2461 poor and 1668 non-poor individuals. All were 65 years old or older at baseline. We used latent class growth analysis to identify trajectory groups' depressive symptoms. Multinomial logistic regression was used to examine how a range of changes in health conditions and social engagement was associated with trajectories among poor and non-poor participants. Among the poor, five heterogeneous trajectories with clear patterns were identified: high-to-moderate, stable-high, slightly-increasing, steeply-increasing, and stable-low. Among non-poor, high-to-moderate, steeply-increasing, and stable-low groups were found. A decrease in health conditions was the most vulnerable subgroup's (steeply-increasing) primary risk factor. Poor older adults who reduced participation in, or decreased contact with, social networks were likely to belong to the steeply-increasing group. Our study provides impetus for organizational and/or environmental support systems to facilitate social engagement among poor older adults. Future research should examine whether the significance of social engagement among poor elders applies in less-developed and developed countries.

Heterogeneous Trajectories of Physical and Mental Health in Late Middle Age: Importance of Life-Course Socioeconomic Positions.

Drawing on life course and cumulative disadvantage theory, this study examines heterogeneous trajectories of functional limitations and depressive symptoms among late middle-aged individuals. This study used prospective data from 6010 adults, 51 to 64 years old, collected over a 12-year-period from the Health and Retirement Study. Considering the empirical proposition that several physical and mental trajectories may exist, Latent Class Growth Modeling was used. Five heterogeneous patterns of joint trajectories (Relatively healthy, Moderately improving, Steadily deteriorating, Steeply deteriorating, and Persistently high comorbid) were identified. Early life adversity was related to an increasing risk of declines in physical and mental health. The Persistently high comorbid class was characterized by a concentration of disadvantages over the life course. The development of public health interventions could help reduce co-existing physical and mental health problems, especially during late middle-age.

Trajectories of Community-Based Service Use: The Importance of Poverty and Living Arrangements.

This study examined how older adults' living arrangements and poverty status affected their use of in-home health, functional, and out-of-home services over time. Using eight waves of data from the Korea Welfare Panel Study, we employed a logistic mixed-effect model to analyze how poverty and living arrangements affect community-based service use. Living-alone older adults and elder-only couples were more likely than co-residing households to use services. Elder-only couples, when poor, were more likely to use in-home and out-of-home services over time. Understanding predictors of community-based service use over time enables researchers and policymakers to better understand the process of aging-in-place.

Life Course Trajectories of Later-Life Cognitive Functions: Does Social Engagement in Old Age Matter?

This study identified differential patterns of later-life cognitive function trajectories and examined to what extent life course factors and social engagement are associated with group trajectories. Data came from seven waves of the Health and Retirement Study (HRS 1998-2010; n = 7374; Observations = 41,051). Latent class growth analysis identified cognitive function trajectory groups, and multinomial logistic regression was used to examine the factors associated with group trajectories. Five heterogeneous trajectories were identified: stable high, stable moderate, stable low, high-to-moderate, and moderate-to-low. Findings suggest that, after adjusting for life course factors, individuals who became volunteers were more likely to belong to one of the two least vulnerable trajectories, stable high or high-to-moderate. Our findings suggest that, despite the cumulative life course factors evident in cognitive decline, social engagement in old age may serve as a potential protective resource.

Simplified LCA and matrix methods in identifying the environmental aspects of a product system.

In order to effectively integrate environmental attributes into the product design and development processes, it is crucial to identify the significant environmental aspects related to a product system within a relatively short period of time. In this study, the usefulness of life cycle assessment (LCA) and a matrix method as tools for identifying the key environmental issues of a product system were examined. For this, a simplified LCA (SLCA) method that can be applied to Electrical and Electronic Equipment (EEE) was developed to efficiently identify their significant environmental aspects for eco-design, since a full scale LCA study is usually very detailed, expensive and time-consuming. The environmentally responsible product assessment (ERPA) method, which is one of the matrix methods, was also analyzed. Then, the usefulness of each method in eco-design processes was evaluated and compared using the case studies of the cellular phone and vacuum cleaner systems. It was found that the SLCA and the ERPA methods provided different information but they complemented each other to some extent. The SLCA method generated more information on the inherent environmental characteristics of a product system so that it might be useful for new design/eco-innovation when developing a completely new product or method where environmental considerations play a major role from the beginning. On the other hand, the ERPA method gave more information on the potential for improving a product so that it could be effectively used in eco-redesign which intends to alleviate environmental impacts of an existing product or process.
