Adverse childhood experiences and social isolation in older adults
Adverse childhood experiences (ACEs) can have lasting life-course consequences, including a potential impact on social isolation in later life. Longitudinal evidence capturing incident isolation is particularly needed, as cross-sectional studies cannot establish the temporal sequence between ACEs and later-life social isolation. However, this longitudinal association remains insufficiently examined, particularly among older adults in Japan. We in…
Can pre-disaster community resilience enhance post-disaster recovery among older adults? A natural experiment in Iwanuma City after the 2011 Great East Japan Earthquake and Tsunami
As large-scale disasters occur more frequently worldwide, understanding how pre-disaster community resilience influences post-disaster recovery has become imperative for disaster risk-reduction policy and practice. This study investigated whether pre-disaster community resilience helped explain post-disaster subjective recovery following the 2011 Great East Japan Earthquake and Tsunami. We conducted a baseline survey of older residents in Iwanuma…
Changes in depressive symptoms following spousal bereavement among Japanese older individuals across the Covid-19 pandemic
This study investigated changes in depressive symptoms among older individuals who experienced spousal bereavement versus those who did not, comparing the periods before and during the COVID-19 pandemic. Using data from the Japan Gerontological Evaluation Study, a nationwide survey, we followed married participants (2016 or 2019) over a three-year period (2019 or 2022). Participants were categorized as either remaining married or having become wi…

Living in High-Rise Apartments and the Frequency of out-of-Home Activities Among Community-Dwelling Older Adults
Home cooking, cooking skills and dementia requiring long-term care
BACKGROUND: People have come to rely on restaurants and takeaway foods, and less on cooking at home. We examined the association between home cooking and dementia incidence, ascertained through administrative long-term care records, and whether the benefits of home cooking differ by cooking skills. METHODS: Participants in the Japan Gerontological Evaluation Study, a population-based cohort study, were followed for 6 years. The incidence of demen…
Participation in community gathering place and social capital
Community gathering places participation was positively associated with nine social capital indicators; frequency of meeting friends (B: 0.55), number of friends seen within a month (B: 0.49), number of community organizations (B: 0.28-0.55), norms of reciprocity (B: 0.18), and attachment (B: 0.15); all results showed p1

Public assistance program and food diversity among older people
Even after adjusting for sociodemographic factors, men recipients of public assistance have less food diversity than non-recipient men. Men recipients were more likely to increase their food diversity by eating together. To ensure recipients' rights to food security, the public assistance program should provide additional support to integrate recipients into communities that enable them to eat together in addition to providing financial support
Group participation and the risk of functional decline in later life
Although group participation benefits older adults' health, its effects may vary by group type. The Japanese Health and Welfare Co-operative (Hew Co-op) organises peer-led group participation called 'Han Kai' meetings to promote health literacy, but the impact of Han Kai participation on health indicators remains unexplored. This study aimed to examine whether the frequency and duration of Han Kai participation were associated with risk of functi…
Predictors of shifts in Internet use and frequency among older adults in Japan before and in later stages of Covid-19
The study identifies the predictors of four patterns of shift in Internet use and frequency among older adults from the pre-COVID-19 to later stages of the pandemic. Our data included 4699 participants from a nation-wide panel study, the Japan Gerontological Evaluation Study from 2019 to 2022. The findings demonstrated that 322 of 1884 (17.1%) nonusers initiated Internet use in 2019, while 418 of 2815 (14.8%) users discontinued Internet use in 20…

Taiso practice and risk of functional disability and dementia among older adults in Japan
Practicing Taiso, including Radio-Taiso, may reduce the risk of dementia in older adults, while practicing other types of Taiso may reduce the risk of functional disability
Association between internet use and annual health checkups among older Japanese adults
This study concludes that there is a positive association between Internet use and participation in annual health checkups among older individuals in Japan. The results suggest that Internet use may serve as a tool to promote preventive healthcare practices in older populations. However, the study underscores the need for further investigation to understand the underlying mechanisms of this association and to establish a causal relationship
Does the neighborhood built and social environment reduce long-term care costs for Japanese older people? The Jages2010-2019 cohort study
Japan's population has been aging steadily, evidenced by it spending JPY 11 trillion (USD 110 billion) on annual long-term care (LTC) costs in 2021. In this context, understanding the factors influencing LTC costs has become increasingly vital. Although studies have reported positive relationships between neighborhood environment and health outcomes, the connection between LTC costs and neighborhood environment remains unclear. To address this ga…

Resilience Factors Affecting Long-Term Trajectories of Depressive Symptoms in the Aftermath of the Great East Japan Earthquake and Tsunami Among Older Adults
Objectives We examined long-term trajectories of depressive symptoms among older adults following exposure to the 2011 Great East Japan Earthquake and Tsunami. We further characterized the pre- and post-disaster social relationship factors that predicted membership in each trajectory group. Methods Data from 4 time points (including pre-disaster data) were used to analyze the depression trajectories of 2,033 survivors through a group-based trajec…
Arts and cultural engagement and subsequent social deficits among older adults
Social disconnection and suicide mortality among Japanese older adults
Avoidance of not only depressive symptoms, but also social disconnection including eating alone, is useful in suicide prevention among older adults
Do disasters exacerbate socioeconomic inequalities in health among older people
Disasters can exacerbate socioeconomic health disparities because of differential exposure (e.g., socioeconomically disadvantaged groups are more likely to be exposed to disaster-related trauma) and differential vulnerability (disadvantaged groups are more likely to suffer health consequences of exposure to trauma). We sought to test whether health disparities among older adults widened in the area which was directly affected by the 2011 Great Ea…
Does social participation foster social support among the older population in Japan? A three-year follow-up study from the Japan gerontological evaluation study
Whether social participation has generated new, healthier social support is unclear.•We prospectively examined whether social participation fosters social support.•Social support was dose-responsive to the number of types of social participation.•Social support was fostered by participating in some type of group at any frequency.•Support to encourage social participation may be effective to enhance social support
Subjective Happiness, Frequency of Laughter, and Hypertension
In recent years, positive psychological factors, such as subjective happiness and laughter, have been reported to be associated with cardiovascular disease. In this study, we examined the relationship of hypertension with subjective happiness and frequency of laughter using the data from the Japan Gerontological Evaluation Study (JAGES). Of the 138,294 respondents, 26,368 responded to a version of the self-administered questionnaire that included…
Associations of Cooking Skill with Social Relationships and Social Capital among Older Men and Women in Japan
The health benefits of social relationships and social capital are well known. However, little research has examined the determinants of social relationships and social capital. We examined whether cooking skill was associated with social relationships and social capital in older Japanese people. We used 2016 Japan Gerontological Evaluation Study data on a population-based sample of men and women aged ≥ 65 years ( n = 21,061). Cooking skill was a…

Pre-pandemic individual- and community-level social capital and depressive symptoms during Covid-19
During a pandemic, it is important to know whether social capital can mitigate the risk of mental disorders, given the restrictions on social interactions. However, evidence using longitudinal data is scarce. This study examined the association between pre-pandemic social capital and depressive symptoms during COVID-19 among older adults. We used longitudinal data from the Japan Gerontological Evaluation Study (JAGES), including 8291 participants…
Predictors of depressive symptoms following the Great East Japan earthquake
Relative deprivation in income and mortality by leading causes among older Japanese men and women
BACKGROUND: Relative deprivation of income is hypothesised to generate frustration and stress through upward social comparison with one's peers. If psychosocial stress is the mechanism, relative deprivation should be more strongly associated with specific health outcomes, such as cardiovascular disease (compared with other health outcomes, eg, non-tobacco-related cancer). METHODS: We evaluated the association between relative income deprivation a…

Intensity of community-based programs by long-term care insurers and the likelihood of frailty
The World Health Organization (WHO) argues that governments can postpone declining capacity of older adults by providing sufficient support. Yet, to our knowledge, no study has focused on the role of local governments for realizing healthy ageing. This study examined the association between the intensity of community-based programs for frailty postponement by long-term care insurers (as municipalities) and the likelihood of frailty. We analyzed r…
Is a hilly neighborhood environment associated with diabetes mellitus among older people? Results from the Jages 2010 study
Combined effects of eating alone and living alone on unhealthy dietary behaviors, obesity and underweight in older Japanese adults
We examined whether eating alone is associated with dietary behaviors and body weight status, and assessed the modifying effects of cohabitation status in older Japanese people. Data from the 2010 Japan Gerontological Evaluation Study, with a self-reported questionnaire for 38,690 men and 43,674 women aged ≥65 years, were used. Eating status was classified as eating with others, sometimes eating alone, or exclusively eating alone. We calculated a…
Community social capital and inequality in depressive symptoms among older Japanese adults
Although studies have suggested that community social capital contributes to narrow income-based inequality in depression, the impacts may depend on its components. Our multilevel cross-sectional analysis of data from 42,208 men and 45,448 women aged 65 years or older living in 565 school districts in Japan found that higher community-level civic participation (i.e., average levels of group participation in the community) was positively associate…
The Rise and Fall of Neurasthenia in Japanese Psychiatry
The history of the theory and treatment of neurosis in modem Japanese psychiatry began with the exploration of the concept of neurasthenia, introduced through German psychiatry and French neurology. An original perspective on the diagnosis and treatment of neuras thenia was developed by Morita who founded Morita Therapy. Neurasthenia gradually came to be discussed in relation to Morita's concept of shinkeishitsu. Since World War II, the term neur…

Barriers to Health Care among the Elderly in Japan
Japan is undergoing a set of health care reforms aimed at cutting rising health care costs and increasing the efficiency of health care delivery. This empirical study used a large-scale community survey on 15,302 elderly people 65 years and older (56.0% women) conducted in seven municipalities in 2006, to reveal clear-cut evidence of barriers to necessary care. The reasons for not getting health care is attributed to health care cost for the elde…
Assessing the association between all-cause mortality and multiple aspects of individual social capital among the older Japanese
Friendship network was a good predictor for all-cause mortality among older Japanese. In contrast, mistrust was associated with lower mortality among women. Studies with social capital indices considering different culture backgrounds are needed
Neighborhood built environment and physical activity of Japanese older adults
Our findings provide mixed support for the association between PA and the characteristics of BE measures, previously used in Western settings. Some characteristics of the neighborhood built environment may facilitate leisure time sports activity, but not increase the total walking time for Japanese older adults

P1-259 Relations between BMI and total and cause specific mortality in Japan
Purpose Within OECD countries, Japan has the lowest percentage (3.4%) of the people with obesity (30≦ body mass index, BMI). This study aims to reveal the relationship between BMI and mortality among older Japanese. Method We started a cohort study (Aichi Gerontological Evaluation Study, AGES) on non- institutionalised elderly aged 65 and over in 2003. We excluded the subjects with missing data and who died within 1 year in 4 year follow-up perio…
P1-199 Limitations of the “high-risk strategy” for long-term disability care prevention
Introduction In 2006, the Japanese government introduced a new prevention policy to limit the growth of old age disability care. The policy is based on what Geoffrey Rose called the “high-risk strategy” of prevention, and seeks to identify individuals with multiple risk factors. We provide cohort data to examine the feasibility of the policy. Methods Older people (≥65 years old, n=11 889) who were independent in activities of daily living were fo…
