Abstract
OBJECTIVE This study aimed to develop a simpler approach for diagnosing sarcopenia by using only bioelectrical impedance vector analysis parameters. METHODS The study design was a cross-sectional study. The research was conducted based on the Itabashi Longitudinal Study on Aging, a community-based cohort study, with data collected from the 2022 and 2023 surveys in Itabashi Ward, Tokyo, Japan. The development cohort consisted of 1146 participants from the 2022 survey, and the validation cohort included 656 participants from the 2023 survey. Both cohorts were comprised of community-dwelling older adults with similar inclusion criteria. Sarcopenia was defined according to the Asian Working Group for Sarcopenia 2019 criteria. The logistic model utilized height divided by impedance at 50 kHz and phase angle to establish a new regression equation to identify sarcopenia. Regression equations were generated for the development cohort and validated for the validation cohort. Discriminatory ability was assessed using the area under the receiver operating characteristic curve (AUC) for men and women. RESULTS The prevalence of sarcopenia was 20.7% and 14.8% in the development and validation cohort, respectively. The AUC (95% confidence interval) of the logistic model in discriminating sarcopenia was 0.92 (0.88, 0.95) for men and 0.82 (0.78, 0.86) for women in the development cohort and 0.85 (0.78, 0.91) for men and 0.90 (0.86, 0.95) for women in the validation cohort. CONCLUSION The study demonstrated that a simple formula using bioelectrical parameters at 50 kHz proved useful in identifying sarcopenia in the older adult population.

Abstract
OBJECTIVE Evaluating muscle quality instead of its mass has gained attention in diagnosing sarcopenia. The aim of this study was to examine whether phase angle (PhA) as a bioelectrical impedance analysis (BIA)-derived muscle quality indicator is associated with overall lower extremity function better than appendicular skeletal muscle mass index (ASMI) in community-dwelling older adults. METHODS This cross-sectional study used data from the Itabashi Longitudinal Study on Aging, a community-based cohort study. A sex-stratified multivariate logistic regression analysis was conducted using PhA and ASMI as exposures, and low physical function defined as short physical performance battery score <10 as the outcome, adjusted for age, being overweight, knee pain, and non-communicable diseases. Discrimination of low physical function was compared using the receiver operating characteristic curve. RESULTS This study included 1464 participants (age 76 [73-80] y; 757 women), with 58 men (8%) and 66 women (9%) exhibiting low physical function. The multivariate odds ratio (OR; 95% confidence interval [CI]) for low physical function among the highest quartile, compared with the lowest quartile were significant in PhA in multiple sites (e.g., OR, 0.09; 95% CI, 0.03-0.32] for men and 0.12; 95% CI, 0.04-0.33 for women in the left leg) but not in ASMI (OR, 0.51; 95% CI, 0.19-1.34 for men and 0.56; 95% CI, 0.21-1.47 for women). Legs and whole-body PhA outperformed the ASMI in discriminating low physical function (P < 0.001). CONCLUSION PhA reflected physical function better than ASMI; using PhA instead of ASMI in BIA-based morphometric evaluation may add information on low physical function and enhance the diagnostic value of sarcopenia.

Abstract
AIM The Questionnaire for Medical Checkup of Old-Old (QMCOO) is a 15-item dichotomous questionnaire developed for the early detection and intervention of frailty in a nationwide health checkup program targeting the old-old (i.e. aged ≥75 years). The Kihon Checklist (KCL) is a 25-item questionnaire widely used for screening and self-monitoring frailty status in administrative settings. With fewer items than the KCL, the QMCOO might expedite the frailty screening process. This study tested whether the QMCOO shows noninferiority in detecting frailty compared with the KCL. METHODS Overall, 645 participants aged ≥75 years in the Itabashi Longitudinal Study on Aging were assessed for their frailty status according to the revised Japanese version of the Cardiovascular Health Study criteria. They also completed the QMCOO and the KCL simultaneously. We compared the discriminative performance of the two questionnaires using non-inferiority testing with an operationally defined non-inferiority margin of 10% of the area under the receiver operating characteristic curve computed from the KCL. RESULTS The prevalence of frailty was 8.8%. The area under the receiver operating characteristic curve for the QMCOO in determining frailty was 0.76 (95% CI 0.70, 0.82), and the corresponding area under the receiver operating characteristic curve for the KCL was 0.77 (95% CI 0.69, 0.84). The QMCOO was not inferior to the KCL for frailty discrimination (P for non-inferiority = 0.006). CONCLUSIONS The accuracy of the QMCOO for determining frailty was not inferior to that of the KCL. The QMCOO might be more acceptable and useful, as it can be applied in a shorter time with fewer questions than the KCL. Geriatr Gerontol Int 2024; 24: 176-181.

Abstract
AIM Although polypharmacy and frailty are concerns in older adults, there is limited understanding of their association, particularly regarding frailty severity and its phenotypes within this population. This study aimed to examine the association between polypharmacy and frailty severity or frailty phenotypes in community-dwelling older Japanese adults. METHODS This cross-sectional study included 1021 older adults from the Itabashi Longitudinal Study on Aging. Men accounted for 45.4%, and the mean age (standard deviation) was 77.9 (5.1) years. Participants were classified into frail (n = 67), pre-frail (n = 543), and robust (n = 411) groups using the revised Japanese Cardiovascular Health Study criteria. Polypharmacy was defined as using five or more self-reported prescription drugs. Ordinal and binomial logistic regression analyses examined the association between polypharmacy and frailty severity or frailty phenotypes (weight loss, weakness, exhaustion, slowness, and low activity). These models were adjusted for age, sex, body mass index, number of comorbidities, living status, employment status, years of education, as well as drinking and smoking habits. RESULTS The prevalence of frailty in participants with and without polypharmacy was 10.1% and 5.0%, respectively. Participants with polypharmacy were more likely to have frailty (adjusted odds ratio [95% confidence interval], 1.89 [1.40-2.57]), weight loss (1.81 [1.00-3.27]), weakness (1.50 [1.08-2.09]), and slowness (2.25 [1.29-3.94]) compared with the no-polypharmacy group. CONCLUSIONS Polypharmacy was associated with frailty severity and three frailty phenotypes. Longitudinal studies are required to investigate whether polypharmacy can predict the development and progression of frailty. Geriatr Gerontol Int 2024; 24: 196-201.

Abstract
Smartwatches (SW) are wearable devices that support daily life and monitor an individual's health and activity status. This information is utilized to promote behavior modification, which could help prevent chronic diseases and manage the health of older adults. Despite being interested in SWs, older adults tend to decrease their SW usage as they age. Therefore, understanding the acceptance of SWs among older individuals can facilitate individual health management through digital health technology. This study investigated the factors associated with the acceptance of SWs among older adults in Japan and the variations in the factors by sex. This study utilized data from the 2022 Itabashi Longitudinal Study on Aging, an ongoing cohort study conducted by the Tokyo Metropolitan Institute for Geriatrics and Gerontology. We included 899 eligible individuals aged ≥65 years. Participants were classified into three groups: possessing SW (possessor group), not possessing SW but interested in possession in the future (interest group), and not interested in possession in the future (non-interest group) using a self-administered questionnaire. The level of SW acceptance was operationally defined as follows: low (non-interest group), medium (interest group), and high (possessor group). Further, we evaluated the association of acceptance and purchase intentions of SWs with sociodemographic variables, technology literacy, and health variables. Among the participants, 4.2% possessed SWs, with no significant sex difference (men, 4.2%; women, 4.3%). Among men, age < 75 years, obesity, diabetes, and dyslipidemia were significantly associated with SW acceptance level. Contrastingly, among women, age < 75 years, living alone, higher household income, and a high score for new device use in the technology literacy category were significantly associated with SW acceptance level. Health-related factors were associated with SW acceptance in men, while technology literacy and sociodemographic factors were associated with SW acceptance in women. Our findings may inform the development of sex-specific interventions and policies for increasing SW utilization among older adults in Japan.

Abstract
OBJECTIVES Although cognitive decline is a well-known mortality risk, it has not been adequately investigated, whether social relationships modify the relationship between cognitive decline and mortality. We examined the modifying effects of social relationships (household composition, social network [frequency of social contact with individuals outside the household], and social participation) on the association between cognitive decline and all-cause mortality in older Japanese people. METHODS In 2015, a baseline questionnaire was distributed to all 132,005 independent community-dwelling individuals aged ≥65 years resident in Adachi Ward of the Tokyo Metropolitan area. The final sample analyzed comprised 74,872 participants (men: 44.9%; mean age: 73.7 ± 6.0 years). Cognitive decline was assessed using a self-administered dementia checklist that was validated using the Clinical Dementia Rating Scale. RESULTS A Cox proportional hazard model with an average follow-up of 1,657 days revealed that cognitive decline was associated with higher mortality (hazard ratio [HR]: 1.37, 95% confidence interval [95% CI]: 1.25-1.50). We identified significant associations among household composition, social networks, and cognitive decline. Stratified analyses indicated that the cognitive decline-mortality association was stronger among participants with low contact frequency (HR = 1.60, 95% CI: 1.39-1.85) than high frequency (HR = 1.24, 95% CI: 1.11-1.39). Conversely, the association was weaker among individuals living alone (HR = 1.13, 95% CI: 0.90-1.40) than among cohabiting individuals (HR = 1.43, 95% CI: 1.29-1.57). CONCLUSIONS Although living alone and having a small social network represent an isolated status, their modifying effects were the opposite. These findings indicate that the isolation type should be considered when implementing support strategies for older adults with cognitive decline or dementia.

Abstract
BACKGROUND Dementia cafés for people with dementia and their caregivers are promoted in national dementia policies. The effect of dementia cafés on people with dementia has been reported through narratives of caregivers who participated the dementia cafés. However, evidence derived from the data, which included only people with dementia, is sparse. The aim of this study is to analyze the narratives of people with dementia in peer support meetings in Tokyo where only people with dementia participate, i.e., caregivers were not present. METHODS People with dementia and older people with subjective cognitive impairment were recruited in our community-based participatory research centre. Based on the qualitative descriptive approach, we conducted a thematic analysis of the field notes, which was made through ethnographical observation of the meetings. RESULTS Twenty-five meetings were held from November 2018 to March 2020. The cumulative total number of participants was 196. First, the symptomatic problems related to living with dementia were mentioned, which were collectively named under the overarching category of 'Experience of living with dementia.' Second, questions and solutions to the various symptoms were discussed, which were named the 'Quest of Symptoms.' Third, we noted the narrative that reflected on daily life, feelings, and the life that one has led, which were named 'Life story.' Fourth, we noted narratives of how symptoms have improved and their world has expanded, which were named 'Hope.' Fifth and most importantly, narratives about compassion for people with dementia in the past and future, as well as for people of the same generation, were discussed, which were named 'Compassion.' CONCLUSIONS The lived experiences of people with dementia were revealed. Participants noted they were not just being cared for but exchanging information and exploring the symptoms; in other words, they were resilient. Furthermore, more positive aspects concerning living with dementia were discussed, such as 'Hope' and 'Compassion.' Further research concerning the discourse of people around the participants is necessary to evaluate the situation from multiple perspectives.

Abstract
AIM To prevent falls among older adults, healthcare professionals need to assess these individuals from multiple perspectives. This study aimed to group community-dwelling older Japanese people based on their physical, mental, cognitive, and oral functions and comorbidities, and compare the history of falling in these groups. METHODS Data were obtained from a cross-sectional survey conducted in 2015 among older residents of a ward of Tokyo. For the survey, a questionnaire was distributed to all residents aged ≥65 years without a certificate of long-term care (n = 132,005). Questions were posed concerning respondents' physical, mental, cognitive, and oral functions; comorbidities; and experience with falling in the past year. Cluster and logistic regression analyses were performed. RESULTS A total of 70,746 participants (53.4%) were included in the analysis. The mean age was 73.6 years old, and 44.9% were male. Four groups were identified in the cluster analysis: the "good general condition group" (n = 37,797, 52.4%), "poor mental function group" (n = 10,736, 14.7%), "moderate physical function group" (n = 13,461, 19.0%), and "poor general condition group" (n = 9,122, 12.9%). A logistic regression analysis with adjusting for socio-demographic characteristics, health behaviors, and fear of falling showed that the odds ratios for the experience of falling within the past year were 1.44 (95% confidence interval: 1.34-1.53), 1.54 (1.44-1.65), and 2.52 (2.34-2.71) in the poor mental function, moderate physical function, and poor general condition groups, respectively, with the good general condition group as the reference. CONCLUSIONS We classified community-dwelling older adults into four groups based on multiple functions and found possible variations in the risk of falling by group. These findings suggest that such classification may be useful for the prevention of falls.

Abstract
Objectives We selected assessment items that can be used to evaluate the physical, mental, and social functions of community-dwelling older people comprehensively and easily, and examined whether these items could predict a future transition to the requirement for nursing care and dementia.Methods We conducted a self-administered mail survey of 4,439 community-dwelling older people, who were not certified as requiring nursing care in 2011. The items for the survey were shortlisted out of a total of 54 items that were selected by referring to existing scales, and the evaluation items were determined by pass rate and factor analysis. The cut-off point of the total scores was estimated by ROC analysis using the certification of requiring long-term care (support level 1 or higher) and level of independence in the daily lives of older people with dementia (independence level I or higher) in 2014 as external criteria. The predictive validity was examined by binomial logistic regression analysis using the cut-off point of the total score and the score of the sub-domains as explanatory variables, and the requirement of nursing care and independence level of dementia in 2014 as objective variables.Results A factor analysis of 1,810 subjects with no deficiencies in the 54 items identified 24 items in five domains (mental health, walking function, Instrumental Activities of Daily Living (IADL), cognitive function, and social support). During the ROC analysis, the cut-off point of the total score was estimated to be 20/21 points (nursing care: AUC 0.75, sensitivity 0.77, specificity, 0.56; dementia: AUC 0.75; sensitivity 0.79, specificity 0.55). The binomial logistic regression analysis showed that persons with a total score of less than 20 points in 2011 were significantly more likely to be certified as requiring nursing care (odds ratio 2.57, 95%CI 1.69-3.92, P<0.01) or show a decline in their independence level of dementia (odds ratio 3.12, 95%CI 1.83-5.32, P<0.01) in 2014. The scores of mental health, walking function, and IADL were significantly associated with certification of requiring nursing care, while walking function and cognitive function were significantly associated with dementia.Conclusion We believe that the selected items in this study can successfully predict a transition to needing nursing care and dementia in the future. In the sub-domains, the results suggested an association with physical and mental function, as has been previously reported, but little association with social function.

Abstract
Introduction Population aging is likely to increase the number of people with dementia living in urban areas. The Trail Making Test (TMT) is widely used as a cognitive task to measure attention and executive function among older adults. Normative data from a sample of community-dwelling older adults are required to evaluate the executive function of this population. The purpose of this study was to examine the Trail Making Test completion rate and completion time among urban community-dwelling older adults in Japan. Methods A survey was conducted at a local venue or during a home visit (n = 1,966). Cognitive tests were conducted as a part of the survey, and TMT Parts A (TMT-A) and B (TMT-B) were completed after the completion of the Japanese version of the Mini-Mental State Examination (MMSE-J). Testers recorded TMT completion status, completion time, and the number of errors observed. Results In the TMT-A, 1,913 (99.5%) participants understood the instructions, and 1,904 (99.1%) participants completed the task within the time limit of 240 s. In the TMT-B, 1,839 (95.9%) participants understood the instructions, and 1,584 (82.6%) participants completed the task within the time limit of 300 s. The completion rate of TMT-B was 90.2 and 41.8% for participants with an MMSE-J score of >23 points and ≦23 points, respectively. Results of multiple regression analyses showed that age, education, and the MMSE-J score were associated with completion time in both TMTs. Conclusion In both TMTs, completion time was associated with age, education, and general cognitive function. However, not all participants completed the TMT-B, and the completion rate was relatively low among participants with low MMSE-J scores. These findings may help interpret future TMT assessments.

Abstract
BACKGROUND The aim of the present study was to explore factors associated with (i) the inability to attend a follow-up assessment in the community-based participatory research (CBPR) framework; (ii) mortality; and (iii) institutionalization, across a 5-year period among older people with cognitive impairment identified via an epidemiological survey. METHODS The participants were 198 older people whose score on the Mini-Mental State Examination was below 24, and who were living in our CBPR region in the Tokyo metropolitan area. Baseline data included sociodemographic factors, health-related factors, social factors, and assessments by healthcare professionals. Over the following 5 years we observed what happened to the subjects within the CBPR framework. Bivariate and stepwise multiple logistic regression analyses were performed to explore the factors associated with the inability to attend a follow-up assessment, 5-year mortality, and institutionalization. RESULTS Participants who did not attend a follow-up assessment tended to live alone. Being older (>80), living with others, frailty, and the need for rights protection and daily living support were associated with increased mortality. Long-term care insurance certification was strongly associated with institutionalization as a natural consequence of the health-care system. Having dementia and low access to doctors were also positively associated with institutionalization. CONCLUSIONS Older people with cognitive impairment who are living alone are at higher risk of being overlooked by society. To move toward more inclusive communities, the following are recommended: (i) more interventions focusing on older people living alone; (ii) social interventions to detect daily life collapse or rights violations; and (iii) more support to help people with dementia continue living in the community.

Abstract
Background Effective strategies to develop dementia-friendly communities (DFCs) are needed in aging societies. We aimed to propose a strategy to develop DFCs from a Japanese perspective and to evaluate an intervention program that adopted the strategy. Methods This study implemented a multi-level intervention that emphasized nurturing community social capital in a large apartment complex in the Tokyo metropolitan area in 2017. We offered an inclusive café that was open for extended hours as a place to socialize and a center for activities that included monthly public lectures. Individual consultation on daily life issues was also available for free at the café. Postal surveys were sent out to all older residents aged 70 years and older in 2016 and 2019. With a one-group pre-test and post-test design, we assessed changes in the proportion of older residents who had social interaction with friends and those who were confident about living in the community, even if they were living with dementia. Results Totals of 2633 and 2696 residents completed the pre and post-intervention surveys, respectively. The mean age of the pre-intervention respondents was 77.4 years; 45.7% lived alone and 7.7% reported living with impaired cognitive function. The proportion of men who had regular social interaction and were confident about living in their community with dementia increased significantly from 38.8 to 44.5% (p = 0.0080) and from 34.1 to 38.3% (p = 0.045), respectively. Similar significant increases were observed in the subgroup of men living with impaired cognitive function, but not in the same subgroup for women. Conclusions The intervention benefitted male residents who were less likely to be involved in the community’s web of social networks at baseline. A strategy to create DFCs that emphasizes nurturing community social capital can form a foundation for DFCs. Trial registration This study was retrospectively registered in the University hospital Medical Information Network (UMIN) Clinical Trial Registry (registry number: UMIN000038193, date of registration: Oct 3, 2019).

Abstract
BACKGROUND The study aim was to identify depressed mood and frailty and its related factors in older people during the coronavirus disease 19 pandemic. METHODS Since 2010, we have conducted questionnaire surveys on all older residents, who are not certified in the long-term care insurance, living in one district of Tokyo municipality. These residents are divided into two groups by birth month, that is those born between April and September and those born between October and March, and each group completes the survey every 2 years (in April and May). Study participants were older residents who were born between April and September and who completed the survey in spring 2018 and in spring 2020, the pandemic period. Depressed mood and frailty were assessed using the Kihon Checklist, which is widely used by local governments in Japan. We had no control group in this study. RESULTS A total of 1736 residents responded to both surveys. From 2018 to 2020, the depressed mood rate increased from 29% to 38%, and frailty increased from 10% to 16%. The incidence of depressed mood and frailty was 25% and 11%, respectively. Incidence of depressed mood was related to subjective memory impairment and difficulty in device usage, and incidence of frailty was related to being older, subjective memory impairment, lack of emotional social support, poor subjective health, and social participation difficulties. CONCLUSIONS Older people with subjective memory impairment may be a high-risk group during the coronavirus pandemic. Telephone outreach for frail older people could be an effective solution. We recommend extending the scope of the 'reasonable accommodation' concept beyond disability and including older people to build an age-friendly and crisis-resistant community.

Abstract
Background As Japanese society continues to age, the isolation of older people is increasing, and community living for people with cognitive impairment is becoming more difficult. However, the challenges faced by people with cognitive impairment living in the community have not been fully explored because of methodological difficulties. This study re-accessed people with cognitive impairment identified in a previous epidemiological survey to explore their current situation and the risk factors associated with all-cause discontinuation of community living. Methods Under a community-based participatory framework, we examined a high-risk approach for people with cognitive impairment and a community action approach in parallel, to build a dementia-friendly community. For the high-risk approach, we achieved stepwise access to 7614 older residents, which enabled us to select and visit the homes of 198 participants with a Mini-Mental State Examination score < 24 in 2016. In 2019, we re-accessed these individuals. For the community action approach, we built a community space in the study area to build partnerships with community residents and community workers and were able to re-access participants using multiple methods. Results We found that 126 (63.6%) participants had continued living in the same community, but 58 (29.3%) had discontinued community living. Of these, 18 (9.1%) had died, 18 (9.1%) were institutionalized, 9 (4.5%) were hospitalized, and 13 (6.6%) had moved out of the community. A multiple logistic regression analysis identified the following risk factors associated with discontinuation of community living: being certified under long-term care insurance, needing housing support, and needing rights protection. Conclusions Three years after the baseline survey, 29.3% of people with cognitive impairment had discontinued community living. Despite having cognitive impairment or living alone, older people were able to continue living in the community if their needs for housing support and rights protection were met. Both social interventions and medical interventions are important to build age-friendly communities.

Abstract
It is estimated that by 2025 the number of people with dementia will reach around 600 thousand, approximately one out of five in the older population in Tokyo, Japan. At the same time, the number of older people living in a single, couple household is expected to increase. We built a community space for older people in the largest housing complex district in Tokyo, and with the goal of creating a dementia friendly community (DFCs). In this study, we used the community-based participatory research approach to create a model of an inclusive community space with a human-rights-based approach, which is embodied in the PANEL framework by the Alzheimer Scotland organization. The community space where everyone, regardless of with or without dementia, can freely spend their time, and seek consultation on healthcare and older care. It also serves as a Dementia Café, where people with dementia can get together and chat. Places open 3 days a week. Those users can casually seek consultation by physicians, health nurses and psychologists. From April 1, 2017 to March 30, 2018, the average number of visitors was 11.6. Number of consultation was 182 times (female 81.3%, 80s’ =31.3%; 70s’ =23.1%). Historically, service delivery for the people with dementia was hospital-based in japan, but our community space established a new method to provide consultation to people with dementia, from a professional perspective, and to cooperate with appropriate social resources and related organizations as needed.

Abstract
BACKGROUND Considering the real-world experiences of those with cognitive impairments is important in building a positive community for older people. Community-based participatory research is an important methodology for investigators focused on improving community health. The aim of this study was to 1) investigate factors associated with the continuation of community dwelling among high-risk older people and 2) to create a model of an inclusive community space for older people in the largest housing complex district in Tokyo. METHODS From 198 residents who completed all three steps (mail, face-to-face, and home-visit) of a previous large-scale epidemiological survey, we identified 66 residents who were at high-risk of moving out of the community. These participants underwent 6 months of regular assessments by experienced researchers to identify the factors associated with continuing to live in the community. We also employed a community action approach to develop a community space for residents in the study district where more than two researchers who were medical professionals served as staff. The services offered by the space were continuously improved according to user feedback. The function of this center was evaluated during interdisciplinary research meetings. RESULTS After 6 months, among the 66 high-risk residents, 49 people were living in the community and 12 people had moved out of the community. Those who could not continue to live in the community had greater unmet needs in terms of social support, especially daily living support and housing support. In addition, their families perceived a heavier burden of care. Interestingly, dementia diagnosis via the DSM-5, clinical dementia rating, physical health, mental health, and long-term care usage did not predict the outcome. Through discussions with guests, we equipped the space with various services such as coordination of community care and networking with existing organizations. CONCLUSIONS Merely providing healthcare and long-term care might not be sufficient to support community living in people with cognitive impairments. Daily living support and housing support should be provided in the context of a broad health services package. For this purpose, creating a comfortable community space for residents and community workers is essential.

Abstract
AIM To clarify the conditions under which dignity is maintained by reviewing the decision-supporting process for a case. METHODS We conducted both a longitudinal epidemiological survey and action research in parallel in a large housing complex district in Tokyo, Japan, using the community-based participatory research framework. Through collaboration with community professionals, we supported an isolated elderly man who refused medical intervention for three years until his death. After his passing, we re-examined all of his records, conducted in-depth interviews with the community professionals, and held a conference to review the process of managing this individual. RESULTS Concerning support for the decision-making, three conclusions were obtained from the data: 1) a decision is not always stated explicitly; 2) a decision should be supported by the team, because mind sometimes changes; and 3) supporting decision-making is a process in itself. For the maintenance of dignity in the medical setting, the following were kept in mind: medical context is not all that is important; supporters should wait for the right moment to intervene, and support should be provided to help the patient keep in touch with other people and the community. CONCLUSIONS While precisely defining dignity can be difficult, we explored the conditions under which dignity could be maintained by reviewing the decision-supporting process for a single case. Geriatricians may encounter difficult and complex cases such as this in the clinical setting, but guidelines cannot cover such diverse cases.

Abstract
Background This study explored the relationship between community social capital and cognitive impairment, with a focus on the buffering role of community social capital in the association between educational disadvantage and cognitive impairment in community-dwelling older adults in Japan. Methods We used data from two population-based, cross-sectional surveys targeting people aged ≥65 years in a suburban city of the Tokyo metropolitan area (n = 897; 49.8% men; average age = 74.4 years). Social capital included social support (emotional and instrumental support) and the strength of social networks (neighborly ties). To create district-level social capital indicators, we aggregated individual responses on social capital within each district. The Mini-Mental State Examination, Japanese version was used for the assessment of cognitive function. Results Using multilevel logistic regression analysis, we found that lower amounts of district-level emotional and instrumental support were associated with a greater likelihood of cognitive impairment among men. For women, district-level emotional support was associated with a greater likelihood of cognitive impairment. Additionally, a strong district-level social network buffered the relationship between low education and cognitive impairment in both sexes. Conclusions Community social capital appears to have a protective role in determining cognitive function in old age. Our findings may facilitate the development of new community-based strategies to combat dementia.

Abstract
AIM Although a dementia-friendly community is a global goal, community-dwelling persons with dementia continue to have unmet care needs. The aim of this study was to explore the characteristics of persons who experience anxiety about the possibility of not receiving proper dementia care should they need it in the future. METHODS A questionnaire was mailed to all residents aged 65 years or older (n = 132 005) living in one Tokyo district. The questionnaire included an item that measured anxiety about the possibility of not receiving proper dementia care as well as items about sociodemographic variables, depressive symptoms, frailty, housebound status, socioeconomic status, social support, access to a general practitioner (GP), and experience of dementia care. RESULTS Of the 74 171 participants who responded to the anxiety item, 58 481 (78.8%) reported anxiety about the possibility of not receiving proper dementia care should they need it in the future. Simultaneous multiple logistic regression analysis indicated that factors associated with this anticipatory anxiety were depressive symptoms, frailty or prefrailty, being female, not being currently socioeconomically disadvantaged, not having someone who can take you to the hospital when you do not feel well, being younger (65-74 years), being married, not trusting in neighbours, higher educational level (>9 years), not having someone to consult when you are in trouble, not working, having been socioeconomically disadvantaged in childhood, only greeting or less with neighbours, and not having the experience of dementia care. Having access to a GP, living alone, and going out less than once a week did not show a significant association. CONCLUSIONS This large-scale study explored factors associated with anticipatory anxiety about the possibility of not receiving proper dementia care should it be needed in the future. Further studies concerning interventions to decrease such anxiety are needed.

Abstract
AIM Building community social capital is important for socially inclusive societies, leading to dementia-friendly communities. However, quantitative evidence is currently lacking regarding the effectiveness of dementia-friendly communities, including the association with community social capital. The current study examined the ecological relationship between social capital and the proportion of people with cognitive decline. METHODS Data were obtained from population-based, cross-sectional surveys (mail-in questionnaire survey and home-interview survey) of community-dwelling older adults aged ≥65 years, living in 17 district areas in Machida City, Tokyo, Japan. Social capital included social networks (neighborly ties) and social support (emotional support and instrumental support). Cognitive function was assessed using the Mini-Mental State Examination, Japanese version (with a cut-off of 23/24). The proportions of people with high social capital and cognitive decline (Mini-Mental State Examination, Japanese version ≤23) were calculated for residential districts and used in the analysis. RESULTS The district-level social capital indicators were positively and moderately correlated with the proportion of people with cognitive decline. After adjusting for the aging rate, educational level and population density of the district, an ordinal logistic regression analysis showed that higher proportions of people with strong neighborly ties and people with strong instrumental support were significantly associated with a higher proportion of people with cognitive decline. This trend was stronger among women than men. CONCLUSIONS People can continue to live in communities with high social capital, even if they are experiencing cognitive decline. Although this study was preliminary, it provided empirical evidence for the benefits of promoting dementia-friendly communities. Geriatr Gerontol Int 2019; 19: 950-955.

Abstract
BACKGROUND In this study, we examined the relationship between childhood socioeconomic status and physical function among older Japanese people, and investigated whether there is a sex variation in this association. METHODS We administered a cross-sectional questionnaire survey to all independent community-dwelling individuals ≥65 years old, living in Adachi Ward, Tokyo (N = 132,005). Participants self-reported their physical function using the Motor Fitness Scale, and we divided the scores into quartiles for analysis. Childhood socioeconomic status was retrospectively assessed according to a single item. RESULTS We analyzed 75,358 questionnaires. The average age of participants was 73.8 ± 6.0 years, and 55.0% were women. An ordered logistic regression analysis showed that lower childhood socioeconomic status was associated with lower physical function, independent of adult sociodemographic factors, health behaviors, and health conditions. This association was stronger in women than in men. CONCLUSIONS Our findings indicate that low childhood socioeconomic status might have a long-term influence on physical function in late life and that this influence varies by sex. Assessment of socioeconomic disadvantage in childhood is important for developing strategies to help older people maintain their physical function longer.

Abstract
Background Despite increasing evidence of an association between childhood socioeconomic disadvantage and cognitive outcomes, such as dementia and cognitive decline, in Western countries, there are no studies on this association from non-Western societies. We investigated the relationship between childhood socioeconomic status (SES) and subjective symptoms of dementia among community-dwelling older Japanese people and examined age and sex variations in this association. Methods Data were derived from a cross-sectional survey for all community-dwelling individuals aged 65 years and over in Adachi, Tokyo (n = 132,005). We assessed subjective dementia symptoms using a self-administered dementia checklist, which was validated by comparison with the Clinical Dementia Rating scale. Results Data from 75,358 questionnaires were analyzed. After adjusting for potential covariates, lower childhood SES was associated with greater likelihood of subjective dementia symptoms. We found a significant interaction between childhood SES and age on subjective dementia symptoms but no interaction between childhood SES and sex. Age-stratified analysis indicated that the association between lower childhood SES and subjective dementia symptoms was stronger in the ≥75 years subgroup than in the 65–74 years subgroup, indicating an effect modification of age on this association. Conclusions Our findings suggested that low SES in childhood might have a long-term influence on dementia symptoms in late life and that this influence varied by age. This differential association might be explained by the social and historical context in Japan (ie, World War II, postwar chaos, and high economic growth) that has shaped participants’ early experiences.

Abstract
AIM Late-life depression is identified less often by general practitioners than depression in younger adults, but failure to have late-life depression recognized in a primary care setting can have fatal consequences. The aim of the present study was to examine the prevalence of depressed mood and loss of interest, and identify associated factors among community-dwelling older adults in a large-scale study. METHODS A questionnaire was mailed to all residents (n = 132 005) aged ≥65 years in one Tokyo district. The questionnaire asked about depressed mood and loss of interest. It also included items measuring sociodemographic variables, physical health-related variables, psychological variables, socioeconomic variables, attitude to the community and the Dementia Assessment Sheet for Community-based Integrated Care System - 21 items. RESULT In total, 19.5% of community-dwelling older people had experienced a depressed mood or loss of interest during the past month. This group also showed increased frailty and a negative attitude towards the community, and were less likely to be economically disadvantaged (although more likely to have had a childhood economic disadvantage). The multivariate analysis showed that increased frailty had the strongest relationship with depressed mood. Survey respondents who had either of these conditions were more likely to receive support from the community-based integrated support center. CONCLUSIONS The present study showed a high prevalence of depressed mood and loss of interest among older people. Frailty was a significant factor, suggesting that collaboration is essential between primary care geriatrics and geriatric psychiatry. Geriatr Gerontol Int 2018; 18: 1567-1572.

Abstract
AIM Many studies have reported the preventive effects of community social capital on health outcomes, such as mortality and incidence of diseases. However, evidence on the association between community social capital and dementia-related outcomes remains sparse. The present study examined the contextual association of social capital with subjective symptoms of dementia among community-dwelling older adults in Japan, using a population-based, large-scale questionnaire survey. METHODS Data were used from a cross-sectional survey for all community-dwelling individuals aged ≥65 years in Adachi Ward, Tokyo (n = 132 005). Subjective dementia symptoms were assessed using a self-administered dementia checklist, which was validated by the Clinical Dementia Rating Scale. Social capital was assessed by neighborhood cohesion (neighborhood trust, neighborhood attachment and sense of belonging to the neighborhood) and neighborhood network (i.e. social relationships with neighbors). Individual responses from each district were aggregated to create indicators of district-level social capital. RESULTS A total of 75 338 questionnaires were analyzed (covering 260 districts). The average age of participants was 73.8 ± 6.0 years (45.0% men). A multilevel binomial logistic regression analysis by sex showed that a denser neighborhood network in a district was associated with a lower likelihood of subjective dementia symptoms (odds ratio 0.89, 95% confidence interval 0.83-0.96) among women. No association was found for men between district-level social capital and subjective dementia symptoms. CONCLUSIONS Fostering structural aspects of social capital in a community is a potential dementia-prevention strategy, and policymakers should focus on such community-based approaches as well as on approaches that target individuals.

Abstract
OBJECTIVES The Mini-Mental State Examination (MMSE) is widely used as a cognitive screening test for older adults; however, cognitive performance can be affected by age, education, and sample selection bias, including time and place. The aims of this study were to examine the distribution of scores on the Japanese version of the MMSE in an urban community sample and to provide normative data for older Japanese adults. METHODS A questionnaire survey was conducted on all residents aged 65 years and older living in an urban district in Tokyo (N = 7682). From among this population, 3000 residents were randomly selected to receive visits from trained nurses and to have their health status checked and their cognitive function examined using the MMSE. RESULTS Of the 2786 eligible residents, the MMSE was administered to 1341 (47%) and successfully completed by 1319 (mean age, 74.4 ± 6.4 years; mean years of formal education, 12.6 ± 2.9). The median score was 28. A total of 143 residents (10.8%) had scores below the traditional 23/24 cutoff point. Younger age and higher education were associated with better performance. Greater variation was seen among the oldest and least educated residents, especially among women. CONCLUSION The results of this study confirm that age and education affect MMSE scores. To ensure the effective use of the MMSE, it is recommended to examine scores corresponding to age and education. The normative data presented are expected to be useful for assessing MMSE scores in older individuals both in and out of the clinical setting. Copyright © 2016 John Wiley & Sons, Ltd.

Abstract
AIM Evaluating effects of an enjoyable walking-habituation program. METHODS We carried out a 12-week intervention, consisting of an enjoyable walking-habituation program based on five principles of brain-activating rehabilitation: pleasant atmosphere, interactive communication, social roles, praising each other and errorless support. The program, once a week for 90 min, was carried out in small groups. Participants were 71 community-dwelling people (72.2 ± 4.3) without dementia. Cognitive function was evaluated in five cognitive domains: memory, executive function, word fluency, visuospatial abilities and sustained attention. Additionally, quality of life, depressive state, functional capacity, range of activities, social network and subjective memory complaints were assessed using questionnaires. Motor function was also evaluated. Measurement was carried out before the observation period, after observation and after intervention. RESULTS A total of 63 participants were included in the analysis. Daily steps, executive function, subjective memory complaints, functional capacity and 5-m maximum walking time significantly improved during the intervention period (after observation to after intervention) compared with the observation period (before the observation period to after observation). No significant differences were seen in other evaluations. At 6 months after the intervention, 52 of 63 participants (82.5%) continued to walk once a week or more, and all of them were confident about continuing to walk in the future. Furthermore, all participants were satisfied with our walking-habituation program and all replied that they felt delighted. CONCLUSION The intervention program, based on the five principles of brain-activating rehabilitation, resulted in improvement of some cognitive and physical functions, as well as a high walking-habituation rate at 6 months' follow up.

Abstract
AIM The aim of this study was to determine whether daytime sleepiness is related to subjective memory impairment among community-dwelling elderly people, after adjustment for psychosocial variables. METHODS Questionnaires were mailed to all 5199 elderly residents living in one area of Tokyo. The questionnaires collected information about sociodemographic variables, subjective memory impairment, and excessive daytime sleepiness, which was measured by the Japanese version of the Epworth Sleepiness Scale. Information was also collected on sleep hygiene, health-related variables, and psychosocial variables, including perceived social support, social withdrawal, and work status. RESULTS Of the 4783 questionnaires that were returned (92.0%), 4185 participants were included in the analysis (valid response rate: 80.5%), after the exclusion of questionnaires with missing data. The average score on the Japanese version of the Epworth Sleepiness Scale was 5.0 ± 3.9 for men and 4.5 ± 3.7 for women. The frequency of excessive daytime sleepiness was 8.3% for men, 5.8% for women, and 7.0% in total. Stepwise multivariate logistic regression revealed the odds ratio of excessive daytime sleepiness as a predictor of subjective memory impairment was 6.06 (95% confidence interval; 3.06-12.03). CONCLUSIONS Elderly people who complain of daytime sleepiness are potential candidates for interventions related to dementia care after careful consideration of other possible causes of sleepiness.

Abstract
AIM The aim of this study was to develop a self-administered dementia checklist (SDC), in order to help community-residing older adults realize their declining functions and encourage them to begin using necessary services, and to examine its factorial validity and internal reliability. METHODS A panel of dementia clinical experts developed a questionnaire according to pre-selected items and conducted a self-administered survey with community-residing people aged 65 + (n=2,483). The team developed a scale through an exploratory factor analysis and item response theory (IRT) analysis (Study 1). Using this scale, they conducted a self-administered survey with community-residing people aged 65 + (n=5,199), conducted another exploratory factor analysis, and developed a 10-item scale. A confirmatory factor analysis was subsequently conducted and reliability coefficients were computed. RESULTS The exploratory factor analysis of the proposed 37 items extracted 5 factors: Factor 1 was named "subjective decline in daily living functioning," and Factor 2 was "subjective cognitive decline" in the early stage of dementia. The team developed a 20-item scale by selecting 10 items from each factor which had high factor loadings and high slope values in the IRT analysis (Study 1). After the exploratory factor analysis of the 20-item scale, they developed a 10-item scale by selecting 5 items from each factor which had strong associations. The confirmatory factor analysis verified the 2-factor model. The Cronbach α coefficients for the subscales of Factors 1 and 2 were 0.935 and 0.834, respectively, and 0.908 for the overall 10-item scale. CONCLUSION The authors developed a 10-item SDC with 2 factors and confirmed its factorial validity and internal reliability.

Abstract
PURPOSE The present study aims to develop a self-administered dementia checklist to enable community-residing older adults to realize their declining functions and start using necessary services. A previous study confirmed the factorial validity and internal reliability of the checklist. The present study examined its concurrent validity and discriminant validity. METHODS The authors conducted a 3-step study (a self-administered survey including the checklist, interviews by nurses, and interviews by doctors and psychologists) of 7,682 community-residing individuals who were over 65 years of age. The authors calculated Spearman's correlation coefficients between the scores of the checklist and the results of a psychological test to examine the concurrent validity. They also compared the average total scores of the checklist between groups with different Clinical Dementia Rating (CDR) scores to examine discriminant validity and conducted a receiver operating characteristic analysis to examine the discriminative power for dementia. RESULTS The authors analyzed the data of 131 respondents who completed all 3 steps. The checklist scores were significantly correlated with the respondents' Mini-Mental State Examination and Frontal Assessment Battery scores. The checklist also significantly discriminated the patients with dementia (CDR = 1+) from those without dementia (CDR = 0 or 0.5). The optimal cut-off point for the two groups was 17/18 (sensitivity, 72.0%; specificity, 69.2%; positive predictive value, 69.2%; negative predictive value, 72.0%). CONCLUSION This study confirmed the concurrent validity and discriminant validity of the self-administered dementia checklist. However, due to its insufficient discriminative power as a screening tool for older people with declining cognitive functions, the checklist is only recommended as an educational and public awareness tool.

Abstract
PURPOSE The aim of this study was to evaluate the impact of memory complaints on quality of life (QOL) in elderly community dwellers with or without mild cognitive impairment (MCI). METHODS Participants included 120 normal controls (NC) and 37 with MCI aged 65 and over. QOL was measured using the Japanese version of Satisfaction in Daily Life, and memory complaints were measured using a questionnaire consisting of four items. The relevance of QOL was evaluated with psychological factors of personality traits, sense of self-efficacy, depressive mood, self-evaluation of daily functioning, range of social activities (Life-Space Assessment), social network size, and cognitive functions including memory. The predictors of QOL were analyzed by multiple linear regression analysis. RESULTS QOL was not significantly different between the NC and MCI groups. In both groups, QOL was positively correlated with self-efficacy, daily functioning, social network size, Life-Space Assessment, and the personality traits of extraversion and agreeableness; QOL was negatively correlated with memory complaints, depressive mood, and the personality trait of neuroticism. In regression analysis, memory complaints were a negative predictor of QOL in the MCI group, but not in the NC group. The partial correlation coefficient between QOL and memory complaints was -0.623 (P < 0.05), after scores of depressive mood and self-efficacy were controlled. Depressive mood was a common negative predictor in both groups. Positive predictors were Life-Space Assessment in the NC group and sense of self-efficacy in the MCI group. CONCLUSIONS Memory complaints exerted a negative impact on self-rated QOL in the MCI group, whereas a negative correlation was weak in the NC group. Memory training has been widely practised in individuals with MCI to prevent the development of dementia. However, such approaches inevitably identify their memory deficits and could aggravate their awareness of memory decline. Thus, it is critical to give sufficient consideration not to reduce QOL in the intervention for those with MCI.
