RESUMO
BACKGROUND: Theories from anthropology, evolutionary psychology, and sociology have focused on the potential adaptive benefits of hobby engagement for mental health in older adults. However, previous studies have used data from single countries, potentially biased by specific measurement and methodological approaches, cohort effects, or cultural specificities. Whether there are genuine benefits for mental health in older adults cross-culturally remains unknown. This study explored the consistency of this association across 16 different nations. METHODS: For this epidemiological study, we used data from adults aged 65 years or older across 16 countries in the USA, Europe, and Asia, represented in five longitudinal studies (ELSA, JAGES, HRS, SHARE and CHARLS; N=93â263, 45-62% female, mean age 72-76 years, data collected 2008-20). We harmonised measures of self-reported engagement in hobbies and past-times, depressive symptoms (validated scales), and Likert scale responses for self-reported health, happiness, and life satisfaction. We conducted fixed-effects models and longitudinal regression models of hobbies and mental health for each country and then pooled in multinational meta-analyses. We accounted for all time-constant factors including those unobserved (eg, genetics, past leisure behaviour, medical history, psychological traits) and identified time-varying factors (eg, sociodemographic background, clinical conditions, daily functioning). We tested the potential moderating effects of country-level determinants of health in meta-regressions and multilevel models. FINDINGS: Meta-analytic fixed-effects findings showed that having a hobby was associated with fewer depressive symptoms (pooled coefficient -0·10, 95% CI -0·13 to -0·07, I2=69·5%, H2=3·28), and higher levels of self-reported health (0·06, 0·03 to 0·08, I2=48·1%, H2=1·93), happiness (0·09, 0·06 to 0·13, I2=67·0%, H2=3·03), and life satisfaction (0·10, 0·08 to 0·12, I2=33·6%, H2=1·51). Results were consistent in meta-analyses of longitudinal regression models testing directionality of findings. Macro-level factors such as life expectancy, world happiness index, country wealth, and income inequality predicted prevalence of hobby engagement, but they showed only marginal moderating effects on the association between hobbies and mental health. INTERPRETATION: Despite some heterogeneity in measurement between the cohorts, the apparent universality of the health benefits of hobbies internationally suggests that facilitating greater opportunities for engagement across demographic groups and between countries could be an important part of multidisciplinary care. Findings have implications for social prescribing schemes (currently in trial in many countries) and multidisciplinary work on origins and human behavioural patterns of hobby engagement.

BACKGROUND: Behavioral and psychological symptoms of dementia (BPSD) are common among people with dementia from the early stages and can appear even in mild cognitive impairment (MCI). However, the prognostic impact of BPSD is unclear. This study examined the association between BPSD and mortality among people with cognitive impairment. METHODS: This longitudinal study involved 1,065 males and 1,681 females (mean age: males = 77.1 years; females = 78.6 years) with MCI or dementia diagnosis, from the National Center for Geriatrics and Gerontology-Life Stories of People with Dementia (NCGG-STORIES), a single-center memory clinic-based cohort study in Japan that registered first-time outpatients from 2010-2018. Information about death was collected through a mail survey returned by participants or their close relatives, with an up to 8-year follow-up. BPSD was assessed using the Dementia Behavior Disturbance Scale (DBD) at baseline. RESULTS: During the follow-up period, 229 (28.1%) male and 254 (15.1%) female deaths occurred. Cox proportional hazards regression analysis showed that higher DBD scores were significantly associated with increased mortality risk among males, but not females (compared with the lowest quartile score group, hazard ratios [95% confidence intervals] for the highest quartile score group = 1.59 [1.11-2.29] for males and 1.06 [0.66-1.70] for females). Among the DBD items, lack of interest in daily living, excessive daytime sleep, and refusal to receive care had a higher mortality risk. CONCLUSIONS: The findings suggest a potential association between BPSD and poor prognosis among males with cognitive impairment.
RESUMO
BACKGROUND: The decision-making of older adults and people with dementia is attracting more attention among healthcare professionals. While cognitive impairment has been examined as a factor related to decision-making, it can also be assumed that involvement in decision-making leads to the maintenance of cognitive function. This study examined the association of the decision-making process with the onset of cognitive impairment. METHODS: We analyzed data from a 2-year longitudinal panel survey of community-dwelling care recipients aged ≥65 years in Japan. The sample included 406 participants who responded to both baseline and follow-up surveys, were cognitively intact at baseline, and had no missing cognitive impairment data regarding onset at follow-up. The status of decision-making involvement was assessed using a single item and classified into four categories: 'very involved,' 'less involved,' 'unclear about desired care,' and 'having no one to share the decision.' RESULTS: Among the participants (women, 65.0%; ≥75 years old: 68.2%), the incidence of cognitive impairment during the follow-up was 26.6%. Multivariable logistic regression showed that, compared with highly involved participants, those who lacked clarity about desired care were more likely to develop an onset of cognitive impairment (odds ratio: 5.49; 95% confidence interval: 1.63-18.54; P = 0.006). CONCLUSION: Even among cognitively intact care recipients, those who are not able to formulate their desired care may be at risk of cognitive decline. Therefore, support for the decision-making process, not limited to the final decision, is essential to improving the prognosis of community-dwelling care recipients.

OBJECTIVES: We developed a predictive model for all-cause mortality and examined the risk factors for cause-specific mortality among people with cognitive impairment in a Japanese memory clinic-based cohort (2010-2018). METHODS: This retrospective cohort study included people aged ≥65 years with mild cognitive impairment or dementia. The survival status was assessed based on the response of participants or their close relatives via a postal survey. Potential predictors including demographic and lifestyle-related factors, functional status, and behavioral and psychological status were assessed at the first visit at the memory clinic. A backward stepwise Cox regression model was used to select predictors, and a predictive model was developed using a regression coefficient-based scoring approach. The discrimination and calibration were assessed via Harrell's C-statistic and a calibration plot, respectively. RESULTS: A total of 2610 patients aged ≥65 years (men, 38.3%) were analyzed. Over a mean follow-up of 4.1 years, 544 patients (20.8%) died. Nine predictors were selected from the sociodemographic and clinical variables: age, sex, body mass index, gait performance, physical activity, and ability for instrumental activities of daily living, cognitive function, and self-reported comorbidities (pulmonary disease and diabetes). The model showed good discrimination and calibration for 1-5-year mortality (Harrell's C-statistic, 0.739-0.779). Some predictors were specifically associated with cause-specific mortality. CONCLUSIONS: This predictive model has good discriminative ability for 1- to 5-year mortality and can be easily implemented for people with mild cognitive impairment and all stages of dementia referred to a memory clinic.

BACKGROUND: Per the biopsychosocial model, pain, especially chronic low back pain, which often presents with nonspecific pain, requires a comprehensive approach involving social factors. However, the association of social factors, including social isolation and loneliness, with this condition remains unclear. This study examined the cross-sectional association of social isolation and loneliness with chronic low back pain among older adults. METHODS: We recruited functionally independent older adults through a mail survey in 2019 from the Japan Gerontological Evaluation Study (JAGES). Chronic low back pain was defined as low back pain lasting more than three months. Social isolation was identified based on face-to-face and non-face-to-face interactions ("not isolated," "isolated tendency," and "isolated"). Loneliness was assessed using the UCLA Loneliness Scale ("not lonely," "lonely tendency," and "lonely"). RESULTS: Consequently, 21,463 participants were analyzed (mean age: 74.4 years; 51.5% females); 12.6% reported chronic low back pain. Multivariable Poisson regression analysis revealed that loneliness was significantly associated with the likelihood of chronic low back pain; compared with "not lonely", the prevalence ratio (PR) was 1.14 (95% confidence interval [CI]: 1.05-1.25) for "lonely tendency" and 1.40 (1.27-1.54) for "lonely." Social isolation was not associated; compared with "not isolated," the PR (95% CI) was 0.96 (0.88-1.05) for "isolated tendency" and 0.99 (0.89-1.10) for "isolated." A positive multiplicative interaction between social isolation and loneliness for chronic low back pain was found. CONCLUSIONS: Lonelier individuals were more likely to experience chronic low back pain, and those with loneliness and social isolation were synergistically more likely for this condition.
RESUMO
OBJECTIVES: Art and cultural activities can benefit mental health. However, there is insufficient evidence on active engagement in art and cultural activities for preventing depressive symptoms among older adults. Therefore, we examined the association of active engagement in art and cultural activities with depressive symptom onset among older adults using 3-year longitudinal data. METHODS: This longitudinal study recruited non-institutionalised older adults independent in daily living from the Japan Gerontological Evaluation Study (JAGES) established in 2010, and those without depressive symptoms were followed for three years. Depressive symptoms were assessed using the 15-item Geriatric Depression Scale. Active engagement in nine art and cultural activities, including Japanese traditional cultural activities, were evaluated (musical performance, singing, dancing, handicrafts, painting, photography, poetry composition, calligraphy, and tea ceremony/flower arrangement). RESULTS: Ultimately, 37,627 older adults without depressive symptoms at baseline were analysed. The participants' mean age (standard deviation) was 72.6 (5.5) years, and 51.5% were female. During the follow-up period, depressive symptoms occurred in 3844 participants (10.2%). Multivariable logistic regression analysis revealed that active engagement in art and cultural activities was inversely associated with depressive symptom onset (odds ratio = 0.80, 95% confidence interval = 0.73-0.87, p < 0.001). This association was confirmed regardless of age, gender, and socioeconomic status. Among the activities, especially dancing and photography were protective against depressive symptoms. CONCLUSION: Active engagement in art and cultural activities may contribute to preventing depressive symptoms among older adults. Promoting art and cultural engagement could be important to protect their mental health.

BACKGROUND: Marital transitions are associated with adverse health events, such as mortality and cardiovascular disease. Since marital transitions (eg, becoming widowed) are unavoidable life events, it is necessary to identify modifiable intermediate outcomes. Thus, we examined the association between marital transitions and vegetable intake among middle-aged and older Japanese adults. METHODS: This longitudinal study included Japanese adults aged 40-79 years who received an annual health checkup between 2007 and 2011 (baseline) and 5 years later (follow-up). Marital transitions were classified as whether and what type of transition occurred during the 5-year period and comprised five groups: consistently married, married to widowed, married to divorced, not married to married, and remained not married. Changes in total vegetable, green and yellow vegetable, and light-colored vegetable intake from baseline to follow-up were calculated using the Food Frequency Questionnaire. RESULTS: Data from 4,813 participants were analyzed (mean age, 59.4 years; 44.1% women). Regarding marital transitions, 3,960 participants were classified as "consistently married," 135 as "married to widowed," 40 as "married to divorced," 60 as "not married to married," and 529 as "remained not married." Multivariable linear regression analysis revealed that compared to consistently married, married to widowed was inversely associated with the change in total vegetable intake (ß = -16.64, SE = 7.68, P = 0.030) and light-colored vegetable intake (ß = -11.46, SE = 4.33, P = 0.008). CONCLUSION: Our findings suggest that being widowed could result in a reduced intake of vegetables. Hence, dietary counseling according to marital situation is necessary.

BACKGROUND: In Asia, where autonomous decision-making is not well accepted, little is known about whether and how individuals' preferences are considered when deciding where they receive care. This study examined whether individuals preferring to age in place if confined to bed were less likely to be institutionalized, using longitudinal data of Japanese older adults. METHODS: We analyzed nationally representative data of 1,290 community-dwelling older adults aged 70 and above. Baseline data were collected in 1999, shortly before the long-term care insurance system was introduced. The outcome was measured as self- or proxy-reported years of institutionalization over seven years. The explanatory variable was whether individuals preferred to age in place if they were confined to bed. Participants were asked about their desired place of care (facility, home, or other) if confined to bed. Covariates were sociodemographic and health-related factors. We used Cox proportional hazards models and calculated hazard ratios (HRs) with 95% confidence intervals (CIs) to evaluate the association of aging-in-place preferences if confined to bed with institutionalization. We applied multiple imputation to deal with missing data. RESULTS: Seventy-eight respondents (6.0%) were institutionalized during the follow-up period. Compared to individuals preferring to reside in long-term care facilities if confined to bed (48.7%), those preferring to stay in their homes (39.6%) were less likely to be institutionalized, even after adjusting for relevant covariates (HR = 0.47, 95% CI 0.27-0.79 for model 1 including residential status; HR = 0.45, 95% CI 0.27-0.76 for model 2 including marital status and co-resident children). CONCLUSIONS: Our findings suggest that individuals' aging-in-place preferences tend to be considered under the long-term care insurance system. Individuals' preferences should be shared with families and clinicians when deciding the place of care.

BACKGROUND: Social distancing measures to prevent the spread of coronavirus disease 2019 may cause changes in psychosocial factors. This study aimed to clarify changes in psychosocial factors among older adults before and after Japan's declaration of a state of emergency over coronavirus disease 2019. METHODS: This was a longitudinal cohort questionnaire study. A baseline survey was conducted in March 2020, and a follow-up survey was conducted in August 2020. The subjects were 1103 community-dwelling older adults not certified as having long-term care needs who responded to both the baseline and follow-up surveys. Changes in psychosocial factors before and after the state of emergency declaration were analysed by gender using the McNemar-Bowker test. RESULTS: Data for 397 men (mean age ± standard deviation: 80.6 ± 4.7 years) and 486 women (80.3 ± 4.3 years) were analysed in this study. The frequency of meeting friends increased over the study period for men (P = 0.04). An increasing number of women lived alone (P = 0.01). However, many people's financial status improved (P < 0.01), and the number of friends met in the previous month increased (P < 0.01). CONCLUSIONS: None of the examined psychosocial factors worsened, except for the increase in the number of women living alone. However, many of the study subjects refrained from engaging in certain activities. If the coronavirus disease 2019 pandemic persists, changes in psychosocial factors may occur. Therefore, a long-term investigation of the secondary psychosocial effects of coronavirus disease 2019 is necessary.

BACKGROUND: Existing evidence suggest that those who are socially isolated are at risk for taking up or continuing smoking. This study investigated country-based differences in social isolation and smoking status. METHODS: We performed a repeated cross-sectional study using two waves of data from two ongoing aging studies: the English Longitudinal Study of Ageing and the Japan Gerontological Evaluation Study. Participants from both studies aged ≥65 years were included. We applied a multilevel Poisson regression model to examine the association between social isolation and smoking status and adjusted for individual sociodemographic characteristics. We used the social isolation index which comprises the following domains: marital status; frequency of contact with friends, family, and children; and participation in social activities. Interaction terms between each country and social isolation were also entered into the mode. RESULTS: After exclusion of never smokers, we analyzed 75,905 participants (7,092 for ELSA and 68,813 for JAGES, respectively). Taking ex-smokers as the reference, social isolation was significantly associated with current smoking; the prevalence ratios (PRs) were 1.06 (95% credible interval [CrI], 1.05-1.08) for men and 1.08 (95% CrI, 1.04-1.11) for women. Taking Japan as a reference, the interaction term between country and social isolation was significant for both sexes, with increased PRs of 1.32 (95% CrI, 1.14-1.50) for men and 1.30 (95% CrI, 1.11-1.49) for women in England. CONCLUSIONS: Older people who were less socially isolated were more likely to quit smoking in England than in Japan, possibly explained by the strict tobacco control policies in England.

BACKGROUND: Second-hand smoke exposure has been associated with poor mental health. However, among Japanese adults, little is known about the association between second-hand smoking and depressive symptoms. We examined this association in a cross-sectional study among a Japanese general adult population sample. METHODS: Japanese adults were recruited from the Japan Multi-Institutional Collaborative Cohort Study in the Okazaki area between 2012 and 2017. Second-hand smoke exposure and smoking status were assessed using a self-administered questionnaire. Based on their frequency of exposure to second-hand smoke, non-smokers and smokers were categorized as "almost never," "sometimes," and "almost every day". Depressive symptoms were defined by a Kessler 6 score ≥5 points. We performed a multivariable Poisson regression analysis to obtain adjusted prevalence ratios (PRs) and 95% confidence intervals (CIs) for depressive symptoms. RESULTS: Overall, 5,121 participants (4,547 non-smokers and 574 smokers) were included whose mean age was 63.6 (standard deviation [SD], 10.3) years for non-smokers and 59.33 (SD, 10.2) years for smokers. The association between second-hand smoking and depressive symptoms was significant among non-smokers, but not among smokers. Among non-smokers, PRs compared with "almost never" were 1.25 (95% CI, 1.09-1.42) for "sometimes" and 1.41 (95% CI, 1.09-1.84) for "almost every day" (P for trend <0.001); among smokers, PRs compared with "almost never" were 1.30 (95% CI, 0.82-2.06) for "sometimes" and 1.44 (95% CI, 0.90-2.33) for "almost every day" (P for trend = 0.144). CONCLUSIONS: Second-hand smoking and depressive symptoms were associated among non-smokers. Our findings indicate the importance of tobacco smoke control for mental health.

OBJECTIVE: We aimed to examine missing data in FFQ and to assess the effects on estimating dietary intake by comparing between multiple imputation and zero imputation. DESIGN: We used data from the Okazaki Japan Multi-Institutional Collaborative Cohort (J-MICC) study. A self-administered questionnaire including an FFQ was implemented at baseline (FFQ1) and 5-year follow-up (FFQ2). Missing values in FFQ2 were replaced by corresponding FFQ1 values, multiple imputation and zero imputation. SETTING: A methodological sub-study of the Okazaki J-MICC study.ParticipantsOf a total of 7585 men and women aged 35-79 years at baseline, we analysed data for 5120 participants who answered all items in FFQ1 and at least 50% of items in FFQ2. RESULTS: Among 5120 participants, the proportion of missing data was 3·7%. The increasing number of missing food items in FFQ2 varied with personal characteristics. Missing food items not eaten often in FFQ2 were likely to represent zero intake in FFQ1. Most food items showed that the observed proportion of zero intake was likely to be similar to the probability that the missing value is zero intake. Compared with FFQ1 values, multiple imputation had smaller differences of total energy and nutrient estimates, except for alcohol, than zero imputation. CONCLUSIONS: Our results indicate that missing values due to zero intake, namely missing not at random, in FFQ can be predicted reasonably well from observed data. Multiple imputation performed better than zero imputation for most nutrients and may be applied to FFQ data when missing is low.

[Purpose] Multidisciplinary treatments are recommended for treatment of chronic low back pain. The aim of this study was to show the associations among multidisciplinary treatment outcomes, pretreatment psychological factors, self-reported pain levels, and history of pain in chronic low back pain patients. [Subjects and Methods] A total of 221 chronic low back pain patients were chosen for the study. The pretreatment scores for the 10-cm Visual Analogue Scale, Hospital Anxiety and Depression Scale, Pain Catastrophizing Scale, Short-Form McGill Pain Questionnaire, Pain Disability Assessment Scale, pain drawings, and history of pain were collected. The patients were divided into two treatment outcome groups a year later: a good outcome group and a poor outcome group. [Results] One-hundred eighteen patients were allocated to the good outcome group. The scores for the Visual Analogue Scale, Pain Disability Assessment Scale, and affective subscale of the Short-Form McGill Pain Questionnaire and number of nonorganic pain drawings in the good outcome group were significantly lower than those in the poor outcome group. Duration of pain in the good outcome group was significantly shorter than in the poor outcome group. [Conclusion] These findings help better predict the efficacy of multidisciplinary treatments in chronic low back pain patients.
RESUMO
OBJECTIVES: Rich social capital is regarded as an individual's social asset, which may contribute to the maintenance of functional ability, even in a state of frailty. This study examined the moderating role of individual social capital in the association between physical frailty and functional ability among older adults. DESIGN: A cross-sectional study. SETTING AND PARTICIPANTS: In total, 522 community-dwelling older adults aged ≥60 years were recruited from among visitors to public facilities, including community cultural centers and gymnasiums in Aichi, Japan. METHODS: Functional ability was assessed using the 5-item subscale of the Tokyo Metropolitan Institute of Gerontology Index of Competence that assesses instrumental self-maintenance, including transportation, finance management, and shopping. Physical frailty was defined by the Fried Frailty Phenotype Questionnaire, including 5 items of fatigue, resistance, ambulation, inactivity, and weight loss, and the participants were classified into 3 groups: non-frailty, pre-frailty, and frailty. Individual social capital was assessed for 2 dimensions: the cognitive dimension (perceptions of community social cohesion) and the structural dimension (informal socializing and social participation). RESULTS: The participants' mean age (SD) was 74.1 (6.5) years and 78.0% were women. Among the participants, non-frailty was 46.6%, pre-frailty was 47.0%, and frailty was 6.5%. Multivariable linear regression analysis revealed that physical frailty was associated with lower levels of functional ability compared with non-frailty [pre-frailty: ß (95% CI) = -0.07 (-0.22 to 0.08), P = .374; frailty: ß = -0.67 (-0.99 to -0.35), P < .001]. However, individual structural social capital showed a negative interaction with physical frailty against low functional ability, indicating a moderating association (P = .027). CONCLUSIONS AND IMPLICATIONS: High levels of individual structural social capital mitigated the adverse association between physical frailty and functional ability. Fostering rich social capital may preserve the functional ability of frail older adults, helping their independent lives in the community.

BACKGROUND: Phase angle, which is associated with cellular health, has attracted attention as a noninvasive and objective method for nutritional assessment. However, the association between malnutrition and phase angle in older inpatients with hip fractures has not been reported. Therefore, this study investigated this association in older inpatients (aged ≥65 years) with hip fractures and determined the cutoff phase angle for determining malnutrition. METHODS: This cross-sectional study retrospectively analyzed the data of 96 inpatients with hip fractures who were hospitalized in rehabilitation units after surgery (male, 29.4%; mean age, 82.4±6.2 years). Nutritional status was assessed using the Geriatric Nutritional Risk Index (GNRI), with malnutrition defined as a GNRI ≥98. Bioelectrical impedance analysis was used to measure phase angles. RESULTS: The phase angle was associated with malnutrition (B=-1.173; odds ratio=0.310; 95% confidence interval 0.58-0.83; p=0.015). The area under the receiver operating characteristic curve was 0.71. The cutoff phase angle for malnutrition was 3.96° (sensitivity=0.85, specificity=0.63). CONCLUSION: Phase angle could be an indicator of malnutrition in older inpatients with hip fractures. Our findings will help formulate rehabilitation strategies for these patients.
RESUMO
Arts and cultural engagement has the potential to reduce social deficits such as loneliness and social isolation. However, as most evidence is from Western countries, less is known whether the protective association of engagement with social deficits can also be seen in different cultural settings such as Asia. We explored the associations of arts and cultural engagement, focusing on engagement continuity and type, with loneliness and social isolation among older adults in Japan, one of the fastest-ageing countries. This three-year longitudinal study involved 4,383 individuals (mean age = 74.3 years; 51.3% women) from the Japan Gerontological Evaluative Study 2019; 2022 waves. To assess engagement continuity, respondents were categorised into four groups: none, decreasing, increasing and sustained engagement. A latent class analysis identified four classes of engagement type: low, receptive, creative and diverse engagement. Loneliness and social isolation were measured using the University of California Los Angeles (UCLA) 3-Item Loneliness Scale (range: 3-9) and the Social Isolation Index (range: 0-5), respectively. We applied ordinary least squares regressions to investigate the associations between engagement and the outcomes. Regarding engagement continuity, those who increased or sustained their engagement across waves reported lower loneliness compared with those who did not engage (increased: coef. = -0.22, 95% confidential interval [CI] = -0.41, -0.04; sustained: coef. = -0.26, 95% CI = -0.36, -0.16). Individuals who sustained their engagement also reported lower social isolation (coef. = -0.18, 95% CI = -0.27, -0.09). Regarding engagement type, engaging in diverse activities was associated with lower loneliness compared to low engagement (coef. = -0.34, 95% CI = -0.59, -0.10), while creative and diverse engagement were associated with lower social isolation (creative: coef. = -0.13, 95% CI = -0.22, -0.04; diverse: coef. = -0.33, 95% CI = -0.54, -0.12). These findings suggest that offering a diversity of creative arts and cultural activities and supporting sustainable engagement of older adults may help alleviate their social deficits.
RESUMO
Despite encouraging multi-generational cohabitation, the population of Japanese people living alone has increased. However, little is known about the association between health and multigenerational cohabitation. This study examined the relationship between self-rated health and living arrangements among Japanese adults using data from the Japan Multi-Institutional Collaborative Cohort Study (2013-2017). The analysis employed multivariate logistic regression to examine the associations. Our results showed no association between living arrangements and self-rated health when stratified by gender. Living alone was found to be associated with poor self-rated health among women aged 65 and above. A similar association may exist among men in the same age group. Among women aged < 65 years, two-generation cohabitation was associated with a good self-rated health, similar to those living alone. Among men aged < 65 years, neither living alone nor two-generation cohabitation was significantly associated with good self-rated health. We found no association between three- or plus-generation cohabitation and self-rated health. Therefore, our findings indicate associations between multigenerational cohabitation and self-rated health, but they vary by gender and age. Invested stakeholders in the public health field should consider the potential impact of living arrangements on health based on gender and age.

BACKGROUND: Although the relationship between medication status, symptomatology, and outcomes has been evaluated, data on the prevalence of polypharmacy and potentially inappropriate medications (PIMs) and the association of polypharmacy and PIMs with swallowing function during follow-up are limited among hospitalized patients aged ≥65 years with dysphagia. METHODS: In this 19-center cohort study, we registered 467 inpatients aged ≥65 years and evaluated those with the Food Intake LEVEL Scale (FILS) scores ≤8 between November 2019 and March 2021. Polypharmacy was defined as prescribing ≥5 medications and PIMs were identified based on the 2023 Updated Beers Criteria. We applied a generalized linear regression model to examine the association of polypharmacy and PIMs with FILS score at discharge. RESULTS: We analyzed 399 participants (median age, 83.0 years; males, 49.8%). The median follow-up was 51.0 days (interquartile range, 22.0-84.0 days). Polypharmacy and PIMs were present in 67.7% of and 56.1% of patients, respectively. After adjusting for covariates, neither polypharmacy (ß = 0.05; 95% confidence interval [CI], -0.04-0.13, p=0.30) nor non-steroidal anti-inflammatory medications (ß = 0.09; 95% CI, -0.02-0.19; p=0.10) were significantly associated with FILS score at discharge. CONCLUSION: The results of this study indicated a high proportion of polypharmacy and PIMs among inpatients aged ≥65 years with dysphagia. Although these prescribed conditions were not significantly associated with swallowing function at discharge, our findings suggest the importance of regularly reviewing medications to ensure the appropriateness of prescriptions when managing older inpatients.
RESUMO
AIMS: Regular self-weighing is effective in weight management and may help to mitigate the risk of underweight among older adults. We examined which factors of oral function are associated with a risk for underweight among community-dwelling older adults and whether regular self-weighing can mitigate that risk. METHODS: This was a cohort study. Self-administered questionnaires were mailed to 7665 older adults in March 2019 (response rate 74.3%) and 7591 in March 2020 (response rate 74.7%). Among those who responded to both surveys, 3594 older adults who were not underweight in March 2019 were included (follow-up rate: 59.2%). We examined the association between dysphagia, poor masticatory function, and dry mouth and the development of underweight, and whether regular self-weighing reduced the risk for underweight. RESULTS: The average age ± standard deviation of participants was 71.1 ± 3.4 years. There was a significant association between swallowing difficulty and the occurrence of underweight (odds ratio = 1.65, p = .012). However, this relationship did not differ significantly with regular self-weighing (p = .477). CONCLUSIONS: These study findings suggest that to prevent underweight among community-dwelling older adults, it is important to focus on those with poor swallowing function.

AIM: To support informal caregivers, a simple assessment tool capturing the multidimensional nature of caregiving experiences, including negative and positive aspects, is required. We developed a short form of the Japanese version of the Caregiver Reaction Assessment (CRA-J), a multidimensional assessment scale for caregiver experiences. METHODS: The internet survey involved 934 Japanese informal caregivers aged 20-79 years (mean age = 58.8 years; 50.2% women) who completed questionnaires, including the CRA-J 18 items (CRA-J-18), consisting of five domains, such as impacts on schedule and finances and positive experiences of caregiving. A 10-item short version of the CRA-J (CRA-J-10; 0-50 points), which was prepared by selecting the two items with the highest factor loadings from each domain, was tested for model fit by confirmatory factor analysis (CFA) and was analyzed for correlations with the CRA-J-18, Zarit Burden Interview (ZBI), Positive Aspects of Caregiving Scale (PACS), Patient Health Questionnaire-9 (PHQ-9), and WHO-Five Well-Being Index (WHO-5). The area under the curve (AUC) in the receiver operating characteristic was evaluated as discriminability for depressive symptoms (PHQ-9 ≥ 10 points). RESULTS: The CFA indicated a good model fit in the CRA-J-10. The CRA-J-10 correlated well with the CRA-J-18 and other variables (CRA-J-18, r = 0.970; ZBI, r = 0.747; PACS, r = -0.467; PHQ-9, r = 0.582; WHO-5, r = -0.588) and showed good discriminant performance for the presence of depressive symptoms (AUC = 0.793, 95% confidence interval = 0.762-0.823). CONCLUSIONS: The CRA-J-10 allows a simple assessment of caregiver experiences, helping support informal caregivers. Geriatr Gerontol Int 2024; 24: 290-296.
