Assessing the visual walkability perceptions of urban streets via the lens of older adults
Gender differences in the long-term impact of early-life exposure to war on physical and mental health
Background: Several studies have examined the impact of exposure to war in early life on long-term health outcomes. However, few studies have examined differences in these effects by gender and type of war. This study examines the impact of exposure to multiple war events before the age of 10 on the long-term physical and mental health of adults aged 65 years and older in China, as well as differences these effects between wars of aggression and …
Domain-staged progression of cognitive impairment in older adults
From Digital Divide to Digital Equality
Objectives The role of information and communication technology (ICT) in later life has received substantial attention, with continuous studies focusing on the digital divide for older persons. Literature usually defines and measures the digital divide by focusing on ICT accessibility, skills, and outcomes. This study attempted to expand this framework by further incorporating the role of learning for a more comprehensive perspective of understan…

This study utilized data from 5 waves (2002, 2005, 2008, 2018, and 2022) of the Chinese Longitudinal Healthy Longevity Survey. We estimated prevalence rates using Poisson regression and Bayesian models from the DemoRates R-package and weighted according to the Chin…
Grandparenting and coresidence preferences in Shanghai, China
Objectives This study aims to examine the living arrangement preferences of older adults in Shanghai, China, with a focus on grandparenting as a shaping factor. Methods This study utilizes data from the 2022 Lifelong Education for Aging Productively in Shanghai survey, which included 1,707 older adults aged 55–85. Since this study focuses on grandparenting, respondents without grandchildren were excluded, resulting in an analytical sample of 1,25…
Self-rated health and interviewer-rated health
Interviewer-rated health (IRH) and self-rated health (SRH) have strong and independent predictive power for mortality, but their relative predictive power has not been examined among subpopulations. Because individuals from different subpopulations have distinct views, understandings, and judgments about health that influence their criteria and referents for SRH, we examine whether IRH is a valid predictor of mortality within subpopulations, whic…

Regression examined the demographic, social and health correlates of the identified factors. Results: Factor analyzes sugge…
Leisure Participation and Cognitive Impairment Among Healthy Older Adults in China
Leisure participation is beneficial to various health outcomes. This study examined a comprehensive list of leisure activities in relation to incidence of cognitive impairment among healthy older adults (65+) in China. Using data from the 2002 to 2018 Chinese Longitudinal Healthy Longevity Survey, we found that most of the leisure activities were protective of cognitive decline and three leisure activities (watching TV, doing housework, and playi…
Impacts of the Covid-19 pandemic on life expectancy at birth in Asia
The COVID-19 pandemic had significantly affected e 0 of Asian populations, and most contribution to the reduction of e 0 came from the three older age groups, 60-79 years, 80 + years, and 45-59 years, with great variations across countries/territories. Our findings could have important implications for development of more resilient public health systems in Asian societies with better policy interventions for vulnerable demographic groups
The Covid-19 pandemic and life expectancy among older adults in Asian countries
Millions of lives in Asia were lost in the ongoing COVID-19 pandemic, causing a reduction of 1.66 years in life expectancy at birth (e0) in 2019–2021 and a reduction of 1.41 years in life expectancy at age 60 (e60). Using the World Population Prospects 2022, we decomposed mortality changes at older ages (ages 60+) that contributed to Asia’s reduction in e0 and e60. Overall, changes in mortality at older ages contributed to more than 70 per cent o…
Diversity of End-of-Life Care in the Boom of Deaths at Old Age
Time trend analysis of leisure-time activity participation among young-old adults in China 2002–2018

Widowhood and Mortality Among Chinese Older Adults in Singapore
Widowhood was associated with increased mortality risk, particularly among recently widowed men and long-term widowed women. Having adequate social support could attenuate the adverse effects of widowhood among older adults
Social support and health among older adults – the Singapore Chinese Health Study
While having social support can contribute to better health, those in poor health may be limited in their capacity to receive social support. We studied the health factors associated with social support among community-dwelling older adults in Singapore. We used data from the third follow-up interviews (2014–2016) of 16,943 participants of the Singapore Chinese Health Study, a population-based cohort of older Singapore Chinese. Participants were …
Validity and reliability of Mini-Mental State Examination in Older Adults in China
The main aim of the study is to validate the factor structure of the Mini-Mental State Examination (MMSE) of China’s older population using the Chinese Longitudinal Healthy Longevity Survey. The validation process used the exploratory factor analysis (EFA) to determine the number of dimensions of MMSE, the confirmatory factor analysis (CFA) to confirm the factorial structure of MMSE, and the factorial invariance to conclude the factor structure d…
Toileting Disability Among Older Adults in China and Role of Environmental Factors
Objectives: We investigated the risk factors associated with toileting disability among older adults in China, focusing on environmental factors (physical, social, and external supports). Methods: Data were drawn from the WHO's SAGE wave 1. We proposed a conceptual framework to guide the selection of risk factors, and implemented logistic regressions separately for urban and rural subpopulations. Results: In both subsamples, older adults who reli…

Age of Retirement and Human Capital in an Aging China, 2015–2050
As China continues to age rapidly, whether the country should adjust the official retirement age, and if so, when and how, are currently major policy concerns. We examine the impact of postponing the retirement age on the human capital of China in the next four decades. Two critical aspects of human capitalhealth and education-are incorporated to account for the quality of the work force. Our projections reveal the impact of nine scenarios on the…
Use of the average age ratio method in analyzing age heaping in censuses
Based on the methods of the average period age ratio and the average cohort age ratio, this study systematically assesses age heaping or digit preference in all population censuses of China. Our study finds that the overall age heaping was relatively low in the Chinese censuses; however, there was a notable preference for ages ending with zero after age 50 in the first two censuses, despite a weakening trend over time. Our study further shows tha…
Trends in ADL and Iadl Disability in Community-Dwelling Older Adults in Shanghai, China, 1998-2008
Shanghai elders experienced substantial improvements in both ADL and IADL disability prevalence over the past decade. The trend toward improvement in IADL function is more consistent and substantial than that of ADL function
Self-Rated Health, Interviewer-Rated Health, and Their Predictive Powers on Mortality in Old Age
Although there is some difference between IRH and SRH, IRH captures similar health information as SRH and is strongly predictive of mortality independent of SRH; thus, IRH could be a good supplementary measurement for well-adopted SRH

What Does Successful Aging Mean? Lay Perception of Successful Aging Among Elderly Singaporeans
As compared with the western model of successful aging, the elderly individuals in Singapore perceived successful aging with a strong focus on familism. These lay perceptions also significantly varied among these elderly individuals
Reciprocal Dynamics of Solo-Living and Health Among Older Adults in Contemporary China
There is a bi-directional relationship between solo-living and well-being/health among the Chinese older adults. Solo-living is a conditioned choice of a set of critical factors among older Chinese. The greater involvement in social/leisure activities is likely a key for Chinese solo-living older adults to mitigate the negative impact of their lower psychological well-being on subsequent mortality
The Impacts of Unmet Needs for Long-Term Care on Mortality Among Older Adults in China
The unmet needs of persons needing long-term care have recently drawn attention in China, the nation with the world’s largest elderly population. Using national panel data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS), we examined the 3-year mortality of 3,089 Chinese adults above the age of 65 years who required long-term care. Long-term care needs were measured by the inability to perform any of the following six activities of …
