Oral hypofunction, resulting from a combined decrease in multiple oral functions, may affect systemic-condition deterioration; however, few studies have examined the association between oral hypofunction and general health among older adults. In this cross-sectional study, we examined the relationship between oral hypofunction and sarcopenia in community-dwelling older adults. We included 878 adults (268 men and 610 women, mean age 76.5 ± 8.3 years). Tongue coating index, oral moisture, occlusal force, oral diadochokinesis (/pa/,/ta/,/ka/), tongue pressure, mas-ticatory function, and swallowing function were evaluated as indicators of oral hypofunction. Grip strength, gait speed, and skeletal muscle mass index were measured as diagnostic sarcopenia parameters. The association between oral hypofunction and sarcopenia was examined via logistic regression using sarcopenia as the dependent variable. Oral hypofunction prevalence was 50.5% overall, 40.3% in men, and 54.9% in women. The prevalence of sarcopenia was 18.6% overall, 9.7% in men, and 22.5% in women. A logistic regression showed oral hypofunction, age, body mass index, higher-level functional capacity, and serum albumin level were significantly associated with sarcopenia. Sarcopenia occurred at an increased frequency in patients diagnosed with oral hypofunction (odds ratio: 1.59, 95% confidence interval: 1.02–2.47); accordingly, oral hypofunction appears to be significantly associated with sarcopenia.

The association between dietary diversity and frailty remains unknown in older people. We evaluated whether a limited dietary variety is associated with frailty in older adults with diabetes mellitus (DM). This cross-sectional investigation included 1357 adults (median age: 77 years, women: 61.3%). DM was determined by self-reporting, the Dietary Variety Score (DVS) was used to evaluate dietary variety, and the revised Japanese version of the Cardiovascular Health Study criteria evaluated frailty. Participants were divided into 4 groups: no DM/high DVS (non-DMHV), no DM/low DVS (non-DMLV), DM/high DVS (DMHV), and DM/low DVS (DMLV). The prevalence of frailty in each group was 3.6%, 6.7%, 6.7%, and 12.2%. After adjusting for covariates, logistic regression analysis revealed the highest odds ratio (OR) of frailty in the DMLV (non-DMLV, OR = 2.18 (95% confidence interval (CI): 1.25–3.83); DMHV, OR = 1.87 (95% CI: 0.63–5.52); DML, OR = 5.03 (95% CI: 2.05–12.35)). Another logistic regression analysis revealed that a low DVS and DM were independently associated with frailty. Both a low dietary variety and DM were independently related to frailty in older people and the combination increased the prevalence of frailty. These findings suggest that high dietary variety could be important for the prevention of frailty in people with DM.

Deterioration of daily activities increases frailty risk. Most of the previous research has examined the association between frailty and specific activities; nevertheless, the diversity of daily activities is also important. Although the type, frequency, and evenness of daily activities have been proposed as indicators of activity diversity, the association between these indicators and frailty remains unclear. In this study, we examined the association between activity diversity and frailty in community-dwelling older adults. This cross-sectional study comprised 658 community-dwelling older adults aged ≥ 65 years who participated in comprehensive health check-ups in 2018. Frailty was defined using the Japanese version of the Cardiovascular Health Study criteria. Three indicators, type, frequency, and evenness of daily activities, were used to assess activity diversity across one week. Multiple logistic regression analyses were performed, with frailty as the dependent variable and the three activity diversity indicators as independent variables. Socio-demographic, physical, and mental functioning factors were adjusted as covariates. Of the 658 participants (median age: 72 years; age range: 65–91 years; 60.5% women), 27 (4.1%) met the criteria for frailty. The frail group had significantly lower scores for type, frequency, and evenness of daily activities, as well as Mini-Mental State Examination scores (all at p < 0.01). We found significant independent associations in all activity diversity indicators with frailty, in multiple logistic models. Activity diversity is independently associated with frailty in community-dwelling older adults.

Objectives: This study aimed to determine the relationship between objective chewing ability and the nutritional status of Japanese community-dwelling elders. Design: A cross-sectional study. Participants: A total of 509 community-dwelling elders living in the Tokyo metropolitan area participated in a comprehensive survey conducted in October 2013. Measurements: The basic characteristics were sex, age, and body mass index. Undernutrition was examined through serum albumin levels. Chewing ability was examined through color-changeable xylitol gum by evaluating the color changes in chewing gum. Nutritional intake was examined using the semi-quantitative food frequency questionnaire. Results: In the poor chewing ability group, all nutrient intake levels were significantly low, except for carbohydrates, and intake levels for all food groups were significantly low, except for cereals, confectionery, sugars, seasonings, and spices. Additionally, after adjusting for covariates for sex, age, Tokyo Metropolitan Institute of Gerontology-Index of Competence (TMIG-IC) score, Mini-Mental State Examination (MMSE) score, body mass index (BMI), stroke, number of functional teeth, energy intake, and protein intake, chewing ability was found to be significantly associated with undernutrition. Conclusion: We concluded that chewing ability was closely associated with nutrient and different food groups’ intake, as well as undernutrition, among Japanese community-dwelling elders. Thus, to ensure comprehensive nutritional management, nutritionists and dentists should collaborate when treating the same patients.

: Preventing social isolation is essential for promoting healthy aging. This study aims to 1) systematically review and synthesize the predictors of objectively measured social isolation from observational studies that have treated isolation as an outcome in community-dwelling older adults, and 2) overview previous studies in this area and reveal an agenda to develop future research. : Peer-reviewed primary studies published in English or Japanese were identified from PubMed, ScienceDirect, PsycINFO, Igaku-Chuo-Zasshi, and CiNii. We followed the PRISMA statement. Risk of bias of included studies was assessed using the Newcastle-Ottawa Scale. : Of the 1,161 studies identified, 10 were included in the review. Most studies were cross-sectional and published in the past 20 years. The risk of bias score ranged from 3 to 6 for the individual studies, indicating a moderate to high risk. The assessment measures for social isolation and proportion of isolated subjects varied greatly across studies. Findings on the predictors of social isolation from each study were clustered into four categories: socio-demographic factors, physical health factors, psychological and cognitive factors, and social and cultural factors. : It was difficult to confirm these predictors conclusively because of the cross-sectional study design and a huge variety of assessment tools for social isolation. This result suggests the need to build consensus on the appropriate scales and standard cut-off points for assessing social isolation. Furthermore, longitudinal studies are urgently required. When considering predictors of social isolation, it is also essential to consider the regional and ethnic background of the samples studied.

Background Predicting incidence of long-term care insurance (LTCI) certification in the short term is of increasing importance in Japan. The present study examined whether the Kihon Checklist (KCL) can be used to predict incidence of LTCI certification (care level 1 or higher) in the short term among older Japanese persons. Methods In 2015, the local government in Tokyo, Japan, distributed the KCL to all individuals older than 65 years who had not been certified as having a disability or who had already been certified as requiring support level 1–2 according to LTCI system. We also collected LTCI certification data within the 3 months after collecting the KCL data. The data of 17,785 respondents were analyzed. First, we selected KCL items strongly associated with incidence of LTCI certification, using stepwise forward-selection multiple logistic regression. Second, we conducted receiver operating characteristic (ROC) analyses for three conditions (1: Selected KCL items, 2: The main 20 KCL items (nos. 1–20), 3: All 25 KCL items). Third, we estimated specificity and sensitivity for each condition. Results During a 3-month follow-up, 81 (0.5%) individuals required new LTCI certification. Eight KCL items were selected by multiple logistic regression as predictive of certification. The area under the ROC curve in the three conditions was 0.92–0.93, and specificity and sensitivity for all conditions were greater than 80%. Conclusions Three KCL conditions predicted short-term incidence of LTCI certification. This suggests that KCL items may be used to screen for the risk of incident LTCI certification.

This study describes shelter operations by public health nurses (PHNs) in Kesennuma City, located near the epicenter of the Great East Japan Earthquake, which occurred on March 11, 2011. The data were semi-structured interviews with 10 PHNs, 2 nutritionists, and 2 general administrators conducted from July 2013 to January 2014. All transcripts were analyzed using the constructivist grounded theory approach. We identified two operating methods for shelters: shelters stationed by PHNs in the Old City, and shelters patrolled by PHNs in the merged district. These methods were compared using four themes. In emergency situations, “operational periods,” a predetermined short term for a leader to perform his/her duties responsibly, could be adopted for relatively small organizations on the frontline. PHNs must not only attempt to operate shelters on their own but also encourage residents to manage the shelters as well. Moreover, human resource allocation should be managed independently of personal factors, as strong relationships between shelter residents would sometimes disturb the flexibility of the response. Even when a situation requires PHNs to stay in shelters, frequent collecting of information and updating the plan according to response progress will help to maintain effective shelter operations.

The incidence of dementia is rapidly increasing worldwide, especially in developed countries. Little is known regarding the effectiveness of dental intervention to prevent dementia or a decline in cognitive functions among community-dwelling elderly subjects, but a few studies have reported a correlation between the lack of regular dental checkups and dementia. For that reason, this study aimed to investigate the effects of oral health intervention on cognitive functions in community-dwelling subjects with a mild cognitive decline via a randomized controlled trial. Fifty-five community-dwelling elderly subjects with a Mini-Mental State Examination score of ≥21 to ≤26 who had not visited a dental clinic in the previous year were randomized to an intervention group (n = 28) or a control group (n = 29). The intervention group received monthly oral health intervention by dental hygienists for 8 months while the control group did not. Data on demographics, cognitive function and oral parameters were collected before and after the intervention. Twenty-five subjects in the intervention group (mean age 77.0 years) and 25 in the control group (mean age 72.8 years) completed the study. Significant improvements were observed in the Trail Making Test (TMT)-A, TMT-B, bleeding on probing rate, oral diadochokinesis, tongue pressure and chewing ability in the intervention group (P < 0.05). There were also significant interactions between the TMT-A and TMT-B scores, oral diadochokinesis, tongue pressure and chewing ability (P < 0.05). Oral health intervention by dental hygienists may be effective for improving the oral health and executive function of cognitive function assessed via TMT.

Ground reaction force (GRF) during sit-to-stand motion is associated with lower extremity strength and balance function. The relationship between GRF and experience of falls has been reported; however, there are no reports on whether GRF can predict the incidence of future falls. We aimed to evaluate the ability of GRF to predict falls and compare GRF with existing predictors. This prospective observational cohort study enrolled 456 community-dwelling older adults living in Itabashi ward who participated in health check-ups in 2016 and 2017. Participants’ physical and cognitive functions were assessed, and the maximum GRF (F), F/weight (F/W), rate of force development (RFD), RFD/W (RFD/weight), and time taken to stand up were evaluated. The following year, participants were asked to report the number of falls during the year. Cox proportional hazards regression was conducted to analyze the relationship between the lowest quintile of each GRF parameter as a predictive factor for falling and assess the annual incidence of falls. Twenty-three participants reported having two or more falls in the previous year. Of all GRF parameters evaluated, only F/W was lower in the fallers than in the non-fallers. After adjusting for sex, age, lifestyle, and comorbidities, F/W was associated with falls in 1 year, and the lowest F/W group had higher risks of falls than the highest F/W group (hazard ratio 2.72, 95 % confidence interval 1.11–6.68). Other measures were not associated with falls. GRF during the sit-to-stand motion might predict the incidence of future falls.

BACKGROUND The Computer-Based Cognitive Assessment Tool (CompBased-CAT) has been reported to have concurrent validity with the Mini-Mental State Examination (MMSE) and discriminating ability for dementia, but it was not clear whether it could predict incidence of cognitive impairment. OBJECTIVE This study examined the ability of the CompBased-CAT to predict mild cognitive impairment (MCI) after 2 years among community-dwelling older adults. METHODS A longitudinal study was conducted, involving 455 older adults (median age 72 years, range 65-89 years, 62.0% female) dwelling in communities. Cognitive function was assessed using the MMSE. MCI was defined as an MMSE score RESULTS After 2 years, 32 (7.0%) of participants developed MCI. ROC curve analysis showed an area under the curve of 0.79, a sensitivity of 0.76, and a specificity of 0.75. Logistic regression analysis showed that total Z-score was significantly associated with prevention of MCI. The odds ratio (OR) was 1.34 (95% confidence interval 1.18-1.52, p<.001). CONCLUSIONS The present study showed that CompBased-CAT has sufficient predictive ability for MCI 2 years later and that it is useful for identifying dementia at an early stage.

Although there is evidence on the predictors of adverse health outcomes in older individuals, walking speed has typically been measured in laboratory settings (LWS); LWS may be distinct from individuals’ actual walking speed in their daily lives (DWS). We examined whether DWS differs from LWS among older adults, and its association with physical frailty. Participants were 90 community-dwelling older adults. A five-meter normal (LWSnor) and maximum (LWSmax) walking speed was measured with a stopwatch. DWS was measured using a global positioning system-related smartphone application for one month during their daily lives. DWSavr, DWSmax, and DWSsd were defined as the average, maximum, and standard deviation of walking speed for one month. Participants’ mean DWSavr and DWSmax were 1.28 m/s and 2.14 m/s, respectively, significantly slower than the mean LWSnor (1.42 m/s) and LWSmax (2.24 m/s); the intraclass correlation coefficient between DWS and LWS were 0.188 to 0.341. DWS was significantly correlated with grip strength, one-legged stance, and LWS. The area under the receiver operating characteristic curve of DWSsd concerning pre-frailty was largest among DWSs, at 0.615, while that of LWSnor was 0.643. The findings suggest that DWS differs from LWS and is associated with physical function and pre-frailty.

Recent research has suggested that the breadth and evenness of activity and activity diversity contribute to health outcomes among older adults. However, few established assessment tools for activity diversity have been developed. This study developed an Activity Diversity Questionnaire (ADQ) for older adults through expert consultation and a preliminary survey among 18 community-dwelling older adults. The diversity score was calculated according to Shannon’s entropy. In study 1, the intraclass correlation coefficients (ICC) of the diversity scores were determined for community-dwelling older adults (n = 30). In study 2, concurrent validity was tested with participants receiving comprehensive health checkups at the Itabashi ward in Japan in 2018 (n = 766). The correlation coefficients of the diversity scores were then calculated in reference to the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence. The final version of the ADQ consisted of 20 total items with excellent test-retest reliability (ICC = 0.84) and moderate correlations with both the Tokyo Metropolitan Institute of Gerontology Index of Competence and Japan Science and Technology Agency Index of Competence (r = 0.48 and 0.60, respectively). The ADQ was developed through scientific procedures and revealed sufficient reliability and validity. As such, it is a scientifically validated tool for assessing activity diversity among older adults.

Sarcopenia is associated with instrumental activities of daily living (IADL) and basic activities of daily living (BADL) disabilities. We developed an index for assessing sarcopenia degree (sarcoscore) and compared it to the Asian Working Group for Sarcopenia (AWGS) criteria. Principal component analyses of walking speed, handgrip strength, and skeletal muscle index were performed to develop a sarcoscore using 3088 Japanese population-based cross-sectional data. During the nine-year follow-up, 278 of 2571 and 88 of 2341 participants developed IADL and BADL disabilities, respectively. Adjusted Cox proportional hazards regression models showed that the sarcoscore criteria, defined as proportional to the sarcopenia prevalence diagnosed by the AWGS criteria, had higher hazard ratios (HRs) and 95% confidence interval (CI) for disability onset than the AWGS criteria (IADL disability: 2.19 (1.64–2.93) vs. 1.79 (1.32–2.43), BADL disability: 4.28 (2.63–6.96) vs. 3.22 (1.97–5.27)). The adjusted HRs for IADL and BADL disabilities were reduced by 4% and 8% per point increase in the sarcoscore, respectively. The sarcoscore assessed the degree of sarcopenia and had a satisfactory performance for predicting functional disabilities in older Japanese adults, suggesting its usefulness as a complementary composite marker for clinical diagnosis.

Aim The Mini‐Mental State Examination is a widely used cognitive assessment tool. However, it has several limitations, including the learning effect and interrater reliability. Therefore, we developed a Computer‐Based Cognitive Assessment Tool (CompBased‐CAT), which runs on a tablet or personal computer. In this study, we examined the validity and discrimination ability of the CompBased‐CAT. Methods Participants were recruited from the Otasha‐Kenshin study carried out in 2016. We included 773 community‐dwelling older individuals in Japan (332 men, 441 women, aged 65–97 years). CompBased‐CAT scores were converted to z‐scores, and the correlation with Mini‐Mental State Examination scores was examined using Pearson's correlation coefficient. Furthermore, the ability to discern cognitive impairment was examined using the receiver operating characteristic curve. Results The Pearson's correlation coefficient for the Mini‐Mental State Examination scores and each task component of the CompBased‐CAT ranged from 0.24 to 0.41 (P < 0.001), and the correlation coefficient of the total z‐scores was 0.51 (P < 0.001). The sensitivity, specificity and area under the receiver operating characteristic curve of the discriminating ability of the CompBased‐CATool for cognitive impairment were 0.81, 0.77 and 0.85, respectively. Conclusions The CompBased‐CAT certainly possesses validity, discriminating ability and utility as a new cognitive assessment tool in community‐dwelling older individuals.

The SARC-F is a recommended screening tool for sarcopenia; however, its sensitivity is reported to be very low. This study aimed to confirm the diagnostic efficacy of the SARC-F and whether it is affected by population characteristics. In this study, 2 cohorts of 1060 community-dwelling older adults, who were monitored by the Tokyo Metropolitan Institute of Gerontology, were included. In addition to the overall dataset, receiver operating characteristic curve analysis was performed to obtain the SARC-F results for sarcopenia among the datasets for only those older in age (over 75 years), those with higher frailty points (above the median total score for the Kihon Checklist points), those with lower grip strength (below the median), lower gait speed (below the median), and those with comorbidities (hypertension, cerebral vascular disease, heart disease, and diabetes mellitus). In the overall dataset, sensitivity and specificity were 3.9% and 97.3%, respectively. In analyzing the area under the curve, sensitivity and specificity for older age and low physical function datasets were significant, but had low values. The diabetes dataset had higher values but did not effectively diagnose sarcopenia at a cutoff value of 4. The SARC-F had high specificity for the diagnosis of sarcopenia in community-dwelling older adults with low physical function. However, its sensitivity was low. Despite these limitations, it may be used as a screening tool for sarcopenia in selected populations, such as adults in hospitals or nursing homes.

Aim The SARC‐F is a useful clinical index for sarcopenia screening; however, this measure has low sensitivity. Furthermore, this tool has never been validated on community‐dwelling older Japanese adults. The goal of the present study was to validate a Japanese version of the SARC‐F and confirm its suitability for Japanese samples. Methods Participants were 734 community‐dwelling older adults in the Itabashi Ward, Japan. Bioimpedance measures, walking speed, grip strength and instrumental activities of daily living (IADL) were measured. Sarcopenia was defined using the European Working Group on Sarcopenia in Older People, the Asian Working Group for Sarcopenia criteria and Japanese‐adjusted Asian Working Group for Sarcopenia. SARC‐F receiver operating characteristic curves for each sarcopenia measure were used to evaluate diagnostic accuracy. Physical functioning, IADL and sarcopenia screening tools were compared with the SARC‐F. Results A total of nine men (3.1%) and 15 women (3.4%) were classified into a SARC‐F sarcopenia group. The sarcopenia group had lower physical functioning and Mini Sarcopenia Risk Assessment scores and higher frailty status than the control group. The Cronbach's alpha for the SARC‐F was 0.610, suggesting insufficient internal consistency. SARC‐F scores were related to physical functioning, IADL, and Mini Sarcopenia Risk Assessment scores. Receiver operating characteristic analyses of the SARC‐F based on each criterion showed low sensitivity, but high specificity. Conclusions The Japanese version of the SARC‐F appears to be a useful index for reflecting physical functioning and IADL. However, it is necessary to further determine whether this tool is useful for detecting sarcopenia among community‐dwelling older adults. Geriatr Gerontol Int 2019; 19: 1172–1178.
