Housing environments, social isolation, and mortality among low-income older renters in the United States
Housing environments constitute a fundamental social determinant of health in later life, yet little is known about how different housing contexts shape survival among economically vulnerable older adults. This study examines whether mortality among low-income older renters follows a graded housing ecology and whether the consequences of social isolation are conditioned by residential context. Using twelve waves (2011-2022) of nationally represen…
Material, Health, and Social Vulnerability and Loneliness Among Older Adults: From the Welfare Regime Perspective
Loneliness in later life is a significant global public health issue that negatively impacts well-being, life satisfaction, and mental health. This study investigates how material, health, and social vulnerabilities contribute to loneliness among older adults using a welfare regime framework. It examines the link between vulnerability and loneliness in the United States, Korea, Sweden, Spain, and Germany using the Health and Retirement Study (HRS…
Community Resources for Older Adults With Age-Related Disabilities and Chronic Conditions: A Scoping Review
Community resources are essential for supporting older adults with disabilities and chronic conditions, yet how these resources are conceptualized and evaluated across the empirical literature remains unclear. This scoping review synthesizes U.S.-based research on community resources for older adults with age-related disabilities and chronic conditions, guided by the PAGER framework. Following PRISMA-ScR guidelines, we searched MEDLINE, PsycINFO,…
End-of-Life Resources and Place of Death by Community-Based Housing Type
As chronic conditions dominate mortality trends, the place of death has emerged as a key marker of end-of-life (EoL) care quality. Although many older adults wish to die at home, structural barriers often lead to institutional deaths, especially among socioeconomically disadvantaged groups. This study investigates how housing types, defined by economic status, affordability, and congregate features, affect place of death in older adults. Drawing …
Covid-19 Imposed Closure of Rural Co-Housing and Loneliness in Older Adults Living Alone: Longitudinal Evidence From South Korea
This study aimed to examine the impact of COVID-19 on loneliness among rural older women in senior cohousing in Korea. Using a natural experimental study design, we investigated how the pandemic-induced closure of cohousing affected the former residents' loneliness. The sample comprised 84 cohousing residents and 51 individuals in conventional homes. The dependent variable is loneliness, and the independent variables include housing transition, s…
Long-term exposure to fine particulate matter, ozone, and greenness and the risk of lung cancer: A retrospective cohort analysis within a national sample cohort

Quality of Life among Low-Income Older Residents in Subsidized Senior Housing: Rural vs. Suburban Comparisons
Older adults living in subsidized senior housing tend to be at risk for poor psychological well-being related to their advanced age and low income. This study aims to explore multilevel factors affecting perceived quality of life (QoL) among non-urban subsidized senior housing residents and to compare these factors between rural and suburban communities. Community/residential-level data were collected from the interviews with residential service …
Gender differences in the mechanism of involuntary retirement affecting loneliness through vulnerability and coping resources
Involuntary retirement is associated with diminished mental health. However, little is known about the mechanism that connects involuntary retirees' coping resources to their loneliness. Gender patterns in the mechanism of involuntary retirement are also unclear. This study examines gender differences in the link between involuntary retirement and loneliness through secondary stressors (material and physical vulnerability) and coping resources (s…
Publicly subsidized senior housing: The national profile of independent living models in South Korea
Understanding alternative senior housing arrangements is important because of the expanding global aging population, increasing cost concerns for long-term care, and the desire of older people to age in place (AIP). Using a convergent mixed-method design, we examined the South Korean case using national data on independent living models for older adults. We examined the socioeconomic and health characteristics of residents and the service and ope…
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,…
The Effect of Social Pension on Material Hardship among Older Adults in Korea: Regression Discontinuity Estimation
The goal of this study was to examine the effect of a social pension programme for older adults in South Korea, Basic Pension Scheme (BPS) on material hardship and subjective well-being. We apply a regression discontinuity design (RDD) to estimate the effect of the BPS on the material hardship and life satisfaction of older people between the ages of sixty-one and sixty-eight. Data come from Korea Welfare Panel Study (KOWEPS) wave 12 survey (2017…

Multi-Dimensional Social Relations and Mental Health among Rural Older Adults
To date, knowledge of the association between social-relational patterns and health among rural elders in non-Western social and cultural contexts is scant. Using regional population data in rural South Korea, this study examines comprehensive social relations among rural elders, and the extent to which heterogeneous patterns of social relations were associated with cognitive impairment and depression. Using comprehensive social-relational indica…
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 200…
The effect of living in communal homes on the depressive symptoms of older women living in rural areas: The mediating role of the socio-physical environment

The results showed the effect of living in VCH on depressive symptoms was mediated di…
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 ( …
Multi-Morbid Health Profiles and Specialty Healthcare Service Use: A Moderating Role of Poverty
Increasing life expectancy in the USA makes a better understanding of the heterogeneous healthcare needs of the aging population imperative. Many aging studies have discovered multimorbid health problems focusing mainly on various physical health conditions, but not on combined mental or behavioral health problems. There is also a paucity of studies with older adults who use professional healthcare services caring for their mental and substance-r…
Patterns of Social Engagement Among Older Adults With Mild Cognitive Impairment
Our findings suggest that social engagement is heterogeneous among people with CIND and that some groups of people with CIND have possibilities of engaging in more social activities, especially in formal social activities. Results also indicate that providing informal social resources may be essential for social programs designed specifically for people with CIND to promote their formal social engagement. Future study is needed to examine possibl…
