RESUMEN
PURPOSE: This study aims to evaluate the utility of body mass index (BMI)-adjusted calf circumference (CC) in estimating skeletal muscle mass and diagnosing sarcopenia, as well as its association with falls, a common adverse event in sarcopenia. METHODS: This study used cross-sectional and longitudinal designs. The CC cut-off values and the diagnosis of sarcopenia were based on valid diagnostic criteria. BMI-adjusted CC was based on previous studies, with muscle mass measured by dual-energy X-ray absorptiometry. To evaluate the diagnostic performance of BMI-adjusted CC for low muscle mass and sarcopenia, receiver operating characteristic curves were generated, and the area under the curve (AUC) values were compared using DeLong's test. Over a 1 year follow-up period, factors associated with falls were examined using logistic regression analysis. RESULTS: In the study of 901 older adults (77.6 ± 6.1 years, 63.6% women), 38.1% of men and 42.1% of women had a BMI outside the 18.5-24.9 kg/m2 range. BMI-adjusted CC significantly lowered the AUC values for diagnosing low skeletal muscle mass and sarcopenia in both sexes (P < 0.001). Longitudinal univariate logistic regression analysis in women revealed that unadjusted CC was not significantly associated with fall risk, whereas BMI-adjusted CC significantly reduced fall risk at higher values. However, this association was no longer present in the multivariate analysis. CONCLUSION: The utility of BMI-adjusted CC in assessing skeletal muscle mass was not confirmed. The potential value of BMI-adjusted CC has been suggested regarding falls. Further research is warranted to better elucidate these findings.
RESUMEN
AIMS/INTRODUCTION: The clinical significance of age-related biomarkers in patients with diabetes has not been fully elucidated. In this study, we aimed to establish models to predict the progression of aging in patients with diabetes using biomarkers. MATERIALS AND METHODS: This single-center, retrospective cohort study included 115 Japanese patients with diabetes aged ≥60 years. Age-related adverse health outcomes were defined as emergency hospitalization, any increase in the level of nursing care certification, admission to a nursing home or death. The associations of age-related biomarker levels (adiponectin, growth differentiation factor 15 [GDF15], C-X-C motif chemokine ligand 9 and apelin) and clinical indicators with age-related adverse health outcomes were evaluated. Factors that predominantly influenced the occurrence of age-related adverse health outcomes were explored using the Cox proportional hazards model. RESULTS: The mean age of the 115 participants was 73 years, 50.6% were men, the mean body mass index and hemoglobin A1c level were 25.3 kg/m2 and 9.79%, respectively. There were 26 age-related adverse health outcomes during the study period (median 1.93, range 0-4.65 years). In a model combining clinical indicators and biomarkers, including the Barthel Index, GDF15 and adiponectin, the occurrence of age-related adverse health outcomes was found to be significantly associated with GDF15 and Barthel Index. The group with both GDF15 and adiponectin levels higher than the median proved to be significantly higher than the group with both lower. CONCLUSIONS: The measurement of GDF15 and adiponectin levels and the Barthel Index might be useful for predicting age-related adverse health outcomes in patients with diabetes.
RESUMEN
OBJECTIVES: The purpose of this study was to determine the associations of vision impairment, hearing impairment, and comorbid vision and hearing impairment [ie, dual sensory impairment (DSI)] on admission to hospital with falls within 3 months of discharge in older patients. DESIGN: This prospective multicenter study included patients admitted to and discharged from geriatric wards at 3 university hospitals and 1 national medical center in Japan between October 2019 and July 2023. SETTING AND PARTICIPANTS: Of 1848 individuals enrolled during the study period, 1141 were excluded, leaving 707 for inclusion in the analysis. METHODS: Participants' background factors were compared in terms of whether they had a fall during the 3 months postdischarge. Logistic regression analysis was then performed using the presence or absence of falls after discharge as the objective variable. Three models were created using vision impairment, hearing impairment, and DSI as covariates. Other covariates included physical function, cognitive function, and depression. In addition, logistic regression analysis was performed with falls during hospitalization as the objective variable. RESULTS: DSI was significantly more common in the falls group (P = .004). Logistic regression analysis showed that the risk of falls after discharge was higher in patients with DSI (odds ratio 3.432, P = .006) than in those with vision or hearing impairment alone. When adjusted for physical function, cognitive function, depression, and discharge location, DSI was significantly associated with an increased risk of falls after discharge (odds ratio 3.107, P = .021). The association between DSI and falls during hospitalization did not reach statistical significance, but a trend was observed. CONCLUSIONS AND IMPLICATIONS: This study is the first to show an association between DSI and falls after discharge. Simple interventions for patients with DSI may be effective in preventing falls, and we suggest that they be actively implemented early during hospitalization.
RESUMEN
INTRODUCTION: Although frailty is a geriatric syndrome that is associated with disability, hospitalization, and mortality, it can be reversible and preventable with the appropriate interventions. Additionally, as the current diagnostic criteria for frailty include only physical, psychological, cognitive, and social measurements, there is a need for promising blood-based molecular biomarkers to aid in the diagnosis of frailty. METHODS: To identify candidate blood-based biomarkers that can enhance current diagnosis of frailty, we conducted a comprehensive analysis of clinical data, messenger RNA-sequencing (RNA-seq), and aging-related factors using a total of 104 older adults aged 65-90 years (61 frail subjects and 43 robust subjects) in a cross-sectional case-control study. RESULTS: We identified two candidate biomarkers of frailty from the clinical data analysis, nine from the RNA-seq analysis, and six from the aging-related factors analysis. By using combinations of the candidate biomarkers and clinical information, we constructed risk prediction models. The best models used combinations that included skeletal muscle mass index measured by dual-energy X-ray absorptiometry (adjusted p = 0.026), GDF15 (adjusted p = 1.46E-03), adiponectin (adjusted p = 0.012), CXCL9 (adjusted p = 0.011), or apelin (adjusted p = 0.020) as the biomarker. These models achieved a high area under the curve of 0.95 in an independent validation cohort (95% confidence interval: 0.79-0.97). Our risk prediction models showed significantly higher areas under the curve than did models constructed using only basic clinical information (Welch's t test p < 0.001). CONCLUSION: All five biomarkers showed statistically significant correlations with components of the frailty diagnostic criteria. We discovered several potential biomarkers for the diagnosis of frailty. Further refinement may lead to their future clinical use.

PURPOSE: This study aimed to investigate how intrinsic capacity (IC) deficit is associated with oral functional decline. METHODS: This cross-sectional study enrolled older adults at a research hospital frailty clinic between July 2021 and May 2023. IC evaluation included the locomotion, cognition, vitality, psychology, and sensory domains. Criteria for deficits were established within each domain, and the number of IC deficit domains was calculated for each patient. Oral function assessment included oral hygiene, oral dryness, occlusal force, tongue-lip motor function, tongue pressure, masticatory function, and swallowing function. Patients who met three or more criteria were classified into the oral hypofunction (OHF) group. Univariate and multivariate logistic regression analyses were performed to investigate the relationship between IC deficit and OHF. RESULTS: Of 222 included patients (mean age 78.3 ± 6.3 years; 39.6% men), 105 (47.3%) met the criteria for OHF. This OHF group showed a significantly higher prevalence of locomotion, cognition, psychology, and sensory domain deficits than the normal oral function group. Multivariate analysis adjusted for age and sex revealed a significant association between IC deficits and OHF (odds ratio [OR], 1.33; 95% confidence interval [CI] 1.04-1.70). A significant association was also observed between the locomotion domain and OHF (OR, 2.06; 95% CI 1.13-3.76). CONCLUSION: This study highlights the potential relationship between the number of IC domain deficits and oral functional decline, with the most significant domain being locomotion. Furthermore, it suggests a possible link between sensory and oral function.
RESUMEN
BACKGROUND: At present, there are no consistent findings regarding the association between physical health loss and mental health in older adults. Some studies have shown that physical health loss is a risk factor for worsening of mental health. Other studies revealed that declining physical health does not worsen mental health. This study aimed to clarify whether the relationship between physical health loss and emotional distress varies with age in older inpatients post receiving acute care. METHODS: Data for this study were collected from 590 hospitalized patients aged ≥ 65 years immediately after their transfer from an acute care ward to a community-based integrated care ward. Emotional distress, post-acute care physical function, and cognitive function were assessed using established questionnaires and observations, whereas preadmission physical function was assessed by the family members of the patients. After conducting a one-way analysis of variance (ANOVA) and correlation analysis by age group for the main variables, a hierarchical multiple regression analysis was conducted with emotional distress as the dependent variable, physical function as the independent variable, age as the moderator variable, and cognitive and preadmission physical function as control variables. RESULTS: The mean GDS-15 score was found to be 6.7 ± 3.8. Emotional distress showed a significant negative correlation with physical function in younger age groups (65-79 and 80-84 years); however, no such association was found in older age groups (85-89, and ≥ 90 years). Age moderated the association between physical function and emotional distress. Poor physical function was associated with higher emotional distress in the younger patients; however, no such association was observed in the older patients. CONCLUSIONS: Age has a moderating effect on the relationship between physical health loss and increased emotional distress in older inpatients after acute care. It was suggested that even with the same degree of physical health loss, mental damage differed depending on age, with older patients experiencing less damage.

BACKGROUND: Japan, which has the world's longest life expectancy, has been reporting rejuvenation of physical function among its older adult population. However, evidence for the incidence of functional disability is limited. This study aimed to investigate the comparison in the incidence of functional disability. DESIGN: We used data from the Japan Gerontological Evaluation Study. SETTING AND PARTICIPANTS: The participants were 2 nonoverlapping cohorts of 22,522 (2010-2013 cohort) and 26,284 (2016-2019 cohort) individuals aged 65 years and older from 5 municipalities who were followed for 3 years each. METHODS: The incidence rates of functional disability during the 3-year follow-up period were compared between cohorts. To examine the incident differences between the cohorts, we adjusted for social participation and 9 additional factors that would be expected to improve with social participation using the Weibull survival models adjusting for municipalities as random effects. The analysis was stratified by age groups (65-74 years old and ≥75). RESULTS: The incidence rate of functional disability per 10,000 person-years decreased from 68.6 (2010-2013 cohort) to 51.4 (2016-2019 cohort) in the 65 to 74 years old group and 380.0 (2010-2013 cohort) to 282.6 (2016-2019 cohort) in the ≥75 group; the hazard ratios (95% CIs) were 0.75 (0.64-0.89) and 0.73 (0.67-0.80), respectively. However, these significant decreases disappeared with adjustments for social participation and additional factors. CONCLUSIONS AND IMPLICATIONS: The incidence of functional disability decreased in a recent cohort, which may be explained by social participation and possibly related factors. Promoting social participation could contribute to a decreasing incidence of functional disability among older adults.

OBJECTIVES: This study examined the diagnostic concordance and characteristics of the oral frailty five-item checklist (OF-5) and oral hypofunction (OHF). MATERIALS AND METHODS: In this extensive cross-sectional study, older adults were enrolled at a research hospital frailty clinic between July 2021 and July 2023. The diagnosis of OF-5 and OHF was conducted using the proposed assessment methods. The concordance rate of these criteria was determined by evaluating each patient and calculating the number of patients meeting each diagnosis's criteria. Patients who tested negative for the OF-5 and OHF criteria and those who met only one criterion were included in the OF-5 and OHF characteristic analysis. RESULTS: A total of 248 patients were included in the analysis (mean age 77.6 ± 6.8 years; 36.7 % men). Among the patients, 114 (46.0 %) and 116 (46.8 %) met the OF-5 and OHF criteria, respectively. Furthermore, 78 (31.5 %) participants met both the OF-5 and OHF criteria, whereas 96 (38.7 %) did not meet either criterion. Moreover, 36 (14.5 %) and 38 (15.3 %) patients tested exclusively positive for OF-5 and OHF, respectively. The OF-5-positive and OHF-negative group showed an older age, lower Mini Nutritional Assessment Short Form score, and higher fall risk than the OF-5-negative and OHF-negative group. However, no significant differences were observed between the OF-5-negative and OHF-positive and OF-5-negative and OHF-negative groups. CONCLUSION: The concordance rate of OF-5 and OHF diagnoses was 70.2 %. OF-5 showed a potential association with nutritional status and fall risk. Further longitudinal analyses are warranted to explore our study results.

BACKGROUND: Although body mass index (BMI) and grip strength (GS) are both predictors of disability, their joint effect on predicting incident disability remains uncertain. We examined whether the effect of BMI on incident disability can be modulated by GS in community-dwelling older people in Japan. METHODS: A total of 1486 community-dwellers in Japan (731 men and 755 women, aged 65-82 years) who participated in the 2nd to 7th waves of the National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA) project, were followed up to 20 years. Twelve subgroups were created according to the intersections of GS (sex-specific tertiles: low, intermediate, and high) and BMI (underweight 1, <18.5; underweight 2, 18.5-<21.5; normal, 21.5-<25.0; and overweight/obese, ≥25.0 kg/m2 ). Incident disability was defined as requiring care need level 1 or higher, as per the long-term care insurance system in Japan. The hazard ratios (HR) and corresponding 95% confidence intervals (CI) of incident disability (the 'high GS-normal BMI' subgroup was used as the reference) were calculated using a multivariable-adjusted Cox proportional hazards model. The model was adjusted for baseline characteristics on sex, participation wave, smoking, depressive symptoms, total physical activity, disease history, education level, residential status, and energy intake. RESULTS: Compared with that for participants in the 'high GS-normal BMI' group, the risk of incident disability was higher for participants in the 'low GS-normal BMI', 'low GS-overweight/obese', 'intermediate GS-underweight 1' and 'intermediate GS-overweight/obese' groups. The multivariable-adjusted HR (95% CI) were 1.72 (1.27-2.32, P value<0.001), 1.81 (1.27-2.58, P value = 0.001), 2.42 (1.35-4.32, P value = 0.003) and 1.53 (1.06-2.20, P value = 0.023), respectively. The results did not change substantially when participants with disability occurring within 1 and 2 years of follow-up were excluded, or when the competing events were death without incident disability or dementia. CONCLUSIONS: The joint effect of BMI and GS was more pronounced in those of normal weight or overweight/obese status and low GS, along with underweight or overweight/obese status and intermediate GS in predicting disability. The lack of observed joint effect for those underweight with low GS was likely due to insufficient sample size. GS consideration is necessary for weight management in older adults, and interventions for individuals who are underweight or overweight/obese with adequate GS need not be prioritized for disability prevention.

INTRODUCTION: Dysregulation of pro-inflammatory chemokines is considered a potential mechanism for the development of age-related medical conditions such as frailty. However, evidence linking circulating chemokines with frailty remains lacking. MATERIALS AND METHODS: We performed a case-control study including 48 cases and 48 controls aged 65-90 years, using the National Center for Geriatrics and Gerontology outpatient registry data. Cases were outpatients with physical frailty and low habitual daily activity. Controls were robust outpatients who performed habitual daily activities. The Japanese version of the Cardiovascular Health Study criteria was used to diagnose physical frailty, and the modified Baecke questionnaire was used to evaluate habitual daily activities. Serum CXCL9 and CXCL10 levels were measured using enzyme-linked immunosorbent assay. RESULTS: The median age (interquartile range) in cases and controls was 78 (73-83) and 76 (72-80) years, with the proportions of men were 47.9% and 43.8%, respectively. In the logistic regression model with adjustment for age, sex, and other confounding factors, the multivariable odds ratios (95% confidence intervals) for the highest versus lowest tertile of CXCL9 and CXCL10 levels were 7.90 (1.61-49.80) and 1.61 (0.42-6.30), respectively. However, we did not observe a linear association between CXCL9 levels and physical frailty components. DISCUSSION/CONCLUSION: Our preliminary data exhibit that circulating CXCL9 levels were positively associated with the odds of physical frailty. However, these findings lack evidence of a dose-response relationship between CXCL9 levels and physical frailty components. Further research with a larger sample size is required to confirm these findings.

Sarcopenic dysphagia (SD) is an emerging concern in geriatric medicine. This study aimed to identify the prevalence, progression, and distinct attributes of SD in patients in the Department of Geriatric Medicine. Older adult patients admitted between 2021 and 2022 were enrolled. The department conducts a comprehensive geriatric assessment (CGA) combined with a multidisciplinary team-based intervention, setting the standard for medical care. We diligently assessed the occurrence and development of dysphagia at both the admission and discharge phases. Of the 180 patients analyzed (38.9% male, mean age 86.0 ± 6.6 years), 22.8% were diagnosed with SD at admission, thrice the rate of other dysphagia variants. Only one patient had new-onset dysphagia during hospitalization, attributed to SD. Patients with SD showed a better recovery rate (18.9%) than those with other dysphagia types. Patients with diminished swallowing capacity had compromised nutritional profiles, diminished energy and protein consumption, and extended fasting durations. Although sarcopenia is a prevalent inducer of dysphagia in older adults, an integrated approach in geriatric medicine involving rehabilitation, nutrition, and dentistry is pivotal. Strategies rooted in CGA promise potential for addressing dysphagia.

Sarcopenia is a geriatric disease associated with increased mortality and disability. Early diagnosis and intervention are required to prevent it. This study investigated biomarkers for sarcopenia by using a combination of comprehensive clinical data and messenger RNA-sequencing (RNA-seq) analysis obtained from peripheral blood mononuclear cells. We enrolled a total of 114 older adults aged 66-94 years (52 sarcopenia diagnosed according to the Asian Working Group for Sarcopenia 2019 consensus and 62 normal older people). We used clinical data which were not included diagnosis criteria of sarcopenia, and stride length showed significance by logistic regression analysis (Bonferroni corrected p = .012, odds ratio = 0.14, 95% confidence interval [CI]: 0.05-0.40). RNA-seq analysis detected 6 differential expressed genes (FAR1, GNL2, HERC5, MRPL47, NUBP2, and S100A11). We also performed gene-set enrichment analysis and detected 2 functional modules (ie, hub genes, MYH9, and FLNA). By using any combination of the 9 candidates and basic information (age and sex), risk-prediction models were constructed. The best model by using a combination of stride length, HERC5, S100A11, and FLNA, achieved a high area under the curve (AUC) of 0.91 in a validation cohort (95% CI: 0.78-0.95). The quantitative PCR results of the 3 genes were consistent with the trend observed in the RNA-seq results. When BMI was added, the model achieved a high AUC of 0.95 (95% CI: 0.84-0.99). We have discovered potential biomarkers for the diagnosis of sarcopenia. Further refinement may lead to their future practical use in clinical use.

Osteosarcopenia is a new definitional approach that can increase the risk of falls and fractures in elderly compared with that of osteoporosis and sarcopenia alone. However, biomarkers for osteosarcopenia have not been well identified. Thus, we aimed to explore the biomarkers of osteosarcopenia, including bone, muscle, and geriatric markers. Outpatients attending a frailty clinic were enrolled in the study. Osteosarcopenia was defined as the coexistence of osteoporosis and sarcopenia. Osteoporosis was defined according to the criteria of the Japan Osteoporosis Society. Sarcopenia was defined according to the Asian Working Group for Sarcopenia consensus (2019). We selected 35 blood/serum pathological parameters, including bone, inflammation, nutritional, and aging markers for the study. Logistic regression analysis for osteosarcopenia was performed to explore the biomarkers of osteosarcopenia. Of the total 600 patients with a mean age of 76.6 years, 595 were enrolled in the registry during the study period. Logistic regression analysis for osteosarcopenia showed that elevated thyroid-stimulating hormone (TSH) (odds ratio [OR]:1.375; 95 % confidence interval [CI]: 1.092-1.731), bone-specific alkaline phosphatase (BAP) (OR: 1.059; 95 % CI: 1.002-1.120), and estimated glomerular filtration rate (eGFR) (OR: 1.029; 95 % CI: 1.007-1.053) increased the likelihood of osteosarcopenia. On the other hand, elevated 25-hydroxyvitamin D (25OHD) (OR: 0.905; 95 % CI: 0.841-0.974), blood urea nitrogen (BUN) (OR: 0.895; 95 % CI: 0.829-0.966) and K (OR: 0.241; 95 % CI: 0.081-0.717) decreased the likelihood of osteosarcopenia. It is worthwhile to examine these biomarkers for older adult outpatients attending a frailty clinic for screening osteosarcopenia. Further studies are needed to investigate the effects of other markers of bone metabolism.

PURPOSE: Previous studies suggest that lower serum levels of dehydroepiandrosterone sulfate (DHEA-S) are associated with physical frailty. Associations with subtypes of physical frailty have not been studied. This study aimed to investigate associations between serum DHEA-S levels and physical frailty and its subtypes in older Japanese community-dwellers using panel data. METHODS: This study was conducted within the National Institute for Longevity Sciences-Longitudinal Study of Aging (NILS-LSA). Repeated measurement data were collected from 1,886 older community-dwellers (60-91 years). Frailty was identified according to modified Cardiovascular Health Study criteria (weight loss, weakness, slowness, exhaustion, low physical activity) and was classified into following subtypes: mobility (weakness/slowness), non-mobility (weight loss/exhaustion), and low physical activity. Associations with serum DHEA-S (sex-specific tertiles [T1-T3]) were estimated by random-effects logistic regression models adjusting for age, sex, education, disease history (stroke, hypertension, heart disease, diabetes), smoking status, depressive symptoms, and survey wave. RESULTS: We found an average prevalence of 6.0% for frailty (mobility subtype, 7.0%; non-mobility subtype, 34.8%; low physical activity subtype, 9.4%) across survey waves. Mean (SD) sex-specific DHEA-S levels (µg/dL) at T1, T2, and T3 were 46.8 (20.8), 88.7 (28.4), and 158.0 (58.9), respectively. Compared with T1, the adjusted ORs (95% CIs) for frailty were 0.69 (0.44, 1.08) for T2 and 0.50 (0.30, 0.83) for T3 (P trend = 0.007). The corresponding values for mobility subtype were 0.80 (0.51, 1.24) for T2 and 0.55 (0.33, 0.90) for T3. CONCLUSION: Higher serum DHEA-S levels were associated with lower risk of frailty, especially mobility-subtype frailty, in older community-dwellers.

BACKGROUND: Diet-induced inflammation may be associated with sarcopenia; however, few reports have examined this relationship. AIM: To examine the association between the dietary inflammatory index (DII) and sarcopenia in older adults who visited a frailty clinic in Japan. METHODS: This cross-sectional study used outpatient data from the Frailty Registry Study. The DII is an index of diet-induced inflammation, and a dietary assessment was performed using a brief self-administered diet history questionnaire to calculate the DII score. We classified DII scores by quartiles (Q1-Q4), and sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 consensus. Logistic regression analyses for sarcopenia were performed. Age, sex, comorbidities, and physical activity were entered as confounding factors (Model 1) and Models 2, 3, and 4 with BMI, protein intake, and energy intake added to Model 1. RESULTS: We included 304 patients in the analysis (mean age, 77.6 ± 6.3 years; female, 67.4%). The prevalence of sarcopenia was 14.5%. Logistic regression analyses showed that DII scores were significantly associated with sarcopenia in Model 1 and 2 (Model 1, reference: Q1, Q4: OR 3.10, P = 0.020; Model 2, Q4: OR 3.40, P = 0,022) but not in Model 3 and 4. DISCUSSION: Diet-induced inflammation is associated with a higher likelihood of sarcopenia; however, this association disappeared after confounding for protein and energy intake. CONCLUSIONS: The results demonstrated that dietary protein and energy parameters were the main drivers for muscle health in medical patients.

AIM: The original Kihon Checklist, validated to predict the incidence of functional disability, has been modified to capture both functional ability (can/cannot) and performing state (do/do not). However, the predictive validity of the modified Kihon Checklist remains unverified. Therefore, this study intends to verify the predictive validity of the modified Kihon Checklist and to clarify whether predictive discrimination differs between the classification method of functional ability and performing state. METHODS: The participants comprised 67 398 older people who responded to the Japan Gerontological Evaluation Study (2016). They were followed for 3.1 years on average. Cox's proportional hazards model with incidence of functional disability as the endpoint was used to calculate the hazard ratio, adjusted for sex and age. The independent variables were judged by two classification methods, functional ability and performing state, using nine indicators based on the modified Kihon Checklist. Additionally, we examined whether the two classification methods produced different C-index estimates. RESULTS: Incidence of functional disability occurred in 6232 participants (9.2%). The adjusted hazard ratio of those to whom the nine indicators applied was significantly higher than that of those to whom they did not. The range of the hazard ratio was 1.50-3.82 for both classification methods. The C-index was slightly higher when the classification was based on performing state than when it was based on on functional ability. CONCLUSIONS: Although predictive discrimination was slightly higher for the performing state than for functional ability, the predictive validity of the modified Kihon Checklist was confirmed for both.

BACKGROUND: Increasing age is associated with frailty and a higher prevalence of overactive bladder (OAB). Given the rapidly increasing proportion of older adults in Japan, a better understanding of the relationship between frailty and OAB is needed to inform future healthcare planning. This study assessed the association between frailty and OAB in older adults in Japan and evaluated the impact on their health-related quality of life (HRQoL). METHODS: This was a cross-sectional re-contact study of respondents who previously completed the National Health and Wellness Survey 2018 in Japan. Participants were aged ≥65 years and Japanese speakers and readers. As part of a customized online survey, participants were screened for frailty using the Kihon Checklist (frail = scores ≥8 points) and OAB using the overactive bladder symptom score (OAB = total score ≥ 3 points and ≥ 2 points on question 3). The primary endpoint was the odds ratio of frailty in older adults with and without OAB assessed using a multivariable logistic regression model. Secondary endpoints were the prevalence rates of OAB and frailty. Exploratory endpoints assessed HRQoL using the Medical Outcomes Study 12-Item Short Form Survey Instrument version 2 (SF-12v2). RESULTS: Overall, 2953 participants were included: 150 (5.1%) were frail OAB, 416 (14.1%) non-frail OAB, 287 (9.7%) frail non-OAB, and 2100 (71.1%) non-frail non-OAB. There was a statistically significant correlation between frailty and OAB demonstrated by an adjusted odds ratio (95% CI) of 2.78 (2.18-3.54; p < 0.001). The prevalence (95% CI) of OAB was 34.3% (29.9-38.8) in frail and 16.5% (15.1-18.0) in non-frail older adults; the prevalence of frailty was 26.5% (22.9-30.1) and 12.0% (10.7-13.3) in older adults with and without OAB. HRQoL was assessed in 150 participants per group. The adjusted HRQoL analyses showed significantly lower scores in participants who were frail OAB vs. frail non-OAB for most of the SF-12v2 scores/sub-component scores. CONCLUSIONS: These data highlight the statistically significant positive correlation between frailty and OAB among older adults in Japan and may provide valuable information on the burden of OAB and frailty on older adults to healthcare professionals when considering future healthcare planning.

PURPOSE: Osteosarcopenia and cognitive frailty are both risk factors for falls and fractures. The purpose of this study was to determine the association between osteosarcopenia and cognitive frailty. MATERIALS AND METHODS: This was a cross-sectional secondary data analysis of the Frailty Registry Study with outpatients aged ≥65 years who visited a frailty clinic at a geriatric hospital. Osteoporosis was defined as a bone mineral density < 70% of the young adult mean. Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 criteria. Cognitive frailty was defined as the coexistence of physical frailty and mild cognitive impairment. Physical frailty was evaluated according to Japanese Cardiovascular Health Study criteria, whereas mild cognitive impairment was defined as a Mini-Mental State Examination score ≥ 24 points and a score ≤ 25 points on the Japanese version of the Montreal Cognitive Assessment. We performed multivariable logistic regression analysis to investigate the association between osteosarcopenia and cognitive frailty. RESULTS: The data of 432 patients were analysed. The prevalence of osteosarcopenia and cognitive frailty was 10.2% and 20.8%, respectively. Logistic regression analysis revealed that osteosarcopenia was independently associated with cognitive frailty with a higher odds ratio than osteoporosis or sarcopenia alone. Lost points in visuospatial abilities/executive functions and orientation were significantly associated with osteosarcopenia. CONCLUSIONS: Combination of osteoporosis and sarcopenia is more likely to be associated with physical and cognitive decline than osteoporosis and sarcopenia alone. The mechanism by which osteosarcopenia is associated with decreased visuospatial abilities/executive functions and orientation needs to be addressed.
