Horizontal inequity in long-term care access under universal coverage in Japan (2001–2022)
BACKGROUND: Japan has achieved universal public coverage of long-term care (LTC) through a mandatory LTC insurance system established in 2000. However, evidence remains limited on whether this system ensures equal access to care based on needs, regardless of the ability to pay. OBJECTIVE: To examine income-related horizontal inequities in LTC utilisation in Japan and assess how equity patterns evolved across care types between 2001 and 2022. METH…
Income-related inequality and horizontal inequity in healthcare utilization under population aging and labor market changes in Japan
Population aging, changes in employment patterns, and widening income disparities have caused concerns about equity in healthcare access within Japan’s universal health insurance system. This study examined income-related inequality and horizontal inequity in healthcare utilization in Japan. Using repeated cross-sectional data from 827,168 individuals aged ≥ 20 years, collected from 13 waves of a nationwide population-based survey (1986–2022), tr…
Evolution of perceived social support and its association with psychological distress among middle-aged and young-old Japanese
These results suggest that most middle-aged and young-old Japanese individuals respond smoothly to declining support from family members by increasing their reliance on support from others
Paradoxical well-being
Our study highlighted the importance of recognizing diverse time-use patterns among caregivers and tailoring support measures accordingly. Policies must also consider cultural values in societies where intensive family caregiving may persist despite accessible public services. Because caregivers may experience both distress and fulfilment, caregiver support should be a critical policy priority
Informal Caregivers’ Benefits of Residing in a Neighborhood with High Social Participation
A pragmatic randomised controlled trial of the effectiveness and cost‐effectiveness of Well Parent Japan in routine care in Japan
BACKGROUND: Well Parent Japan (WPJ) is a new hybrid group parent training programme combining sessions to improve mothers' psychological well-being with a culturally adapted version of the New Forest Parenting Programme (NFPP). This study investigates the effectiveness and cost-effectiveness of WPJ against treatment as usual (TAU) within Japanese child mental health services. METHODS: TRANSFORM was a pragmatic multi-site randomised controlled tri…
Evolution of psychological distress with age and its determinants in later life
The results suggest the need for policy support to encourage middle-aged and older adults to promote health and increase social participation in order to prevent depression while aging
Education level as a predictor of the onset of health problems among China’s middle-aged population
Background: Despite the importance of midlife with reference to one's health, educational inequalities in midlife health have attracted little attention in China. Using Cox proportional hazards regression analysis, this study examined the association between educational attainment and the onset of midlife health problems and investigated the potential mediating effects of socioeconomic position (SEP) other than educational attainment, depression,…
Evolutions of Self-Rated Health and Social Interactions during the Covid-19 Pandemic Affected by Pre-Pandemic Conditions
The Coronavirus disease 2019 (COVID-19) pandemic has affected individuals' self-rated health (SRH) and social interactions, but their evolution during the pandemic needs further investigation. The present study addressed this issue using longitudinal data from 13,887 observations of 4177 individuals obtained from a four-wave nationwide, population-based survey conducted between January and February 2019 (before the pandemic) and November 2022. We…
Impact of residing in neighborhoods of high social participation on health of retired workers
Retirement is a key determinant of health among middle-aged and older adults. Social participation (SP) has a favorable impact on health outcomes. Combining these two issues, we examined how neighborhood-level SP may affect the health outcomes of retired workers. We used 94,661 longitudinal observations of 13,185 full-time workers aged 50-59 years in 2005 from a nationwide 14-wave survey conducted in Japan from 2005 to 2018. First, we computed ne…
At Which Area Level Does Covid-19 Infection Matter Most for an Individual’s Self-Rated Health? A Multilevel Fixed-Effects Model Analysis in Japan
Several studies have reported the adverse impacts of the COVID-19 pandemic on health outcomes. However, little is known about which area of COVID-19 infection matters most for an individual's subjective health outcomes. We addressed this issue in the present study. We used the longitudinal data of 2260 individuals obtained from a two-wave internet-based nationwide survey conducted in Japan. We estimated the multilevel regression models, which con…
Trends and Determinants of Cigarette Tax Increases in Japan
Cigarette prices in Japan are lower than those in most other high-income countries. A more striking fact is that cigarette tax revenues have been kept almost flat at just over two trillion JPY (Japanese yen; 18.2 billion US dollars) over more than three decades, despite steadily declining cigarette sales and seemingly weakening pressure from stakeholders with a vested interest in the tobacco industry. We attempted to examine trends and determinan…
Does Residing in a Neighborhood of High Social Participation Postpone Deterioration in Health among Middle-Aged Adults? A Multilevel Survival Analysis in Japan
How does area-level deprivation depress an individual’s self-rated health and life satisfaction? Evidence from a nationwide population-based survey in Japan
Results showed that area-level deprivation modestly decreased an individual's general health conditions and subjective well-being, underscoring the need for public health policies to improve area-level socioeconomic conditions
The elderly’s health capacity to work in China
China’s rapidly aging population has diminished its labor force. This study examines the extent to which the elderly’s labor force participation could be enhanced given their health status. Using national aggregated data from the population census for 1990–2015 and survey data from the Chinese Health and Retirement Longitudinal Study for 2011–2015, we simulated the potential and additional work capacity of China’s elderly using methods employed i…
The impact of social insurance on health among middle-aged and older adults in rural China
The results provide limited evidence of the positive impact of social insurance on health among middle-aged and older adults in rural China. Thus, social insurance programs should be reformed to enhance their positive impact on health
Impact of social participation on health among middle-aged and elderly adults
SP had a positive, albeit selective, impact on health outcomes among middle-aged and elderly adults in China. The results suggest that policy measures to encourage these individuals to engage in SP are needed to enhance their health
Relative Deprivation, Poverty, and Mortality in Japanese Older Adults
Most studies have evaluated poverty in terms of income status, but this approach cannot capture the diverse and complex aspects of poverty. To develop commodity-based relative deprivation indicators and evaluate their associations with mortality, we conducted a 6-year follow-up of participants in the Japan Gerontological Evaluation Study (JAGES), a population-based cohort of Japanese adults aged 65 and older. We analyzed mortality for 7614 respon…
Exploring the health-relevant poverty line
The results suggest that there is a risk that the conventionally defined poverty line may underestimate poverty in terms of population health
Educational level as a predictor of the incidences of non-communicable diseases among middle-aged Japanese
Results underscored the importance of educational level as a predictor of the incidences of selected NCDs, especially among women, with limited mediating effects of other SES and health behaviour
Does social participation accelerate psychological adaptation to health shocks? Evidence from a national longitudinal survey in Japan
Which is riskier for mental health, living alone or not participating in any social activity? Evidence from a population-based eleven-year survey in Japan
Is a positive association between female employment and fertility still spurious in developed countries
The cross-sectional association between female employment and fertility across developed countries turned from negative to positive during the mid-1980s. The conventional view is that the observed positive association is spurious owing to country-specific
Association between successful smoking cessation and changes in marital and job status and health behaviours
The results underscore the association of smoking cessation with changes in marital and job status and health behaviours and imply the need for policy measures to improve health behaviours to promote smoking cessation
Widening disparities in health between educational levels and their determinants in later life
The results suggested that policy measures that encourage social participation and promote healthy behaviors can improve educational disparities in health in later life

The association between individual-level social capital and health
BACKGROUND: It is well known that individual-level social capital is positively associated with health, but most preceding studies have not fully controlled for an individual's time-invariant attributes, especially unobserved ones. The current study attempted to address how the association between individual-level social capital and health is confounded by an individual's unobserved time-invariant attributes. METHODS: Data were collected from six…

Gender-specific linkages of parents’ childhood physical abuse and neglect with children’s problem behaviour
The intergenerational impact of parental childhood abuse on children's problem behaviour is gender specific, i.e. largely characterized by the same gender linkages. Further studies that explore the mechanisms involved in the intergenerational impact of childhood abuse are needed

Response to Dr Ramiro Manzano Nunez's comments
I sincerely appreciate Dr Ramiro Manzano Nunez's comments on my article,1 which examined how the association between individual-level social capital and health is confounded by an individual's unobserved time-invariant attributes. He stressed the importance of linking social capital in addition to bonding and bridging social capital, which I addressed in my article. He suspected that the lack of this component could confound my results. I agree t…
