RESUMEN
Sarcopenic dysphagia is defined as dysphagia caused by sarcopenia of the whole body and swallowing-related muscles. We present a case of sarcopenic dysphagia with improved swallowing function after strength training of swallowing-related muscles using neuromuscular electrical stimulation (NMES). A 78-year-old man was admitted to our hospital with an intraductal papillary mucinous tumor of the pancreatic duct. After admission, the patient developed aspiration pneumonia and was placed on strict bed rest without oral intake, which resulted in progressive malnutrition. At the start of swallowing rehabilitation, he had whole-body sarcopenia, nutritional impairment, and weakness in swallowing-related muscles, with a maximum tongue pressure of 21.4 kPa and an opening force of 5.1 kg. In the videofluoroscopic swallowing study, he aspirated 3 cc of a moderately thick liquid. Consequently, as part of swallowing rehabilitation, strengthening training of swallowing-related muscles with NMES was undertaken for about three weeks. As a result, the maximum tongue pressure and opening force improved to 28.4 kPa and 6.8 kg, respectively. A subsequent videofluoroscopic swallowing study showed no obvious aspiration during any procedure. The patient was discharged on the 86th day on a regular diet. As a component of swallowing rehabilitation, NMES may offer therapeutic benefits for patients with sarcopenic dysphagia.
RESUMEN
Bone quality is an essential factor determining bone strength. However, the relationship between physical activity (PA) and bone quality remains unclear. This study aimed to ascertain the relationship between bone quality and PA using a cortical bone quantitative ultrasound device that measures components of bone quality. In this cross-sectional study, bone quality was assessed in community-dwelling older adults by measuring the cortical speed of sound (cSOS) at the mid-tibia using a quantitative ultrasound device. Using a wrist-worn accelerometer, we calculated the daily duration of moderate-to-vigorous physical activity (MVPA) and light physical activity (LPA) based on estimated METs from the accelerometer data, without differentiating between types of activities. A multiple regression analysis was performed to examine the association between PA and the cSOS. The participants' physical activity averaged 42.0 min/day for MVPA and 483.6 min/day for LPA. No significant association was observed between PA and bone quality in either men or women in the crude models. Furthermore, PA was not significantly correlated with the cSOS in the models adjusted for age, body mass index, nutrient intake, number of medications, and kidney disease. This study was a cross-sectional study which focused on the association between bone quality in older adults and their current amount of PA. The cSOS, as a measure of bone quality, was not associated with PA in men or women. Higher amounts of daily PA, as estimated from metabolic equivalents with an accelerometer, may not necessarily maintain or improve bone quality in older adults. This study does not rule out the potential for a positive association between PA levels or types and bone quality in younger or middle-aged individuals. It was specifically targeted at older adults, and its findings should not be generalized to younger populations. Further longitudinal studies are required to better understand the relationship between PA and bone quality.
RESUMEN
AIM: We aimed to identify the factors contributing to subjective well-being in community-dwelling older adults in rural Japan. This study explored the relationship among physical and mental health, socioeconomic status, and activity levels with regard to the subjective well-being of older adults. METHODS: In the Frail Elderly in the Sasayama-Tamba Area study, a cohort investigation of independent older adults in a rural Japanese community, 541 of 844 participants completed a 2-year follow-up survey. Subjective well-being was assessed as a binary based on three factors - "happiness," "satisfaction with life" and "meaning in life" - using a subset of the World Health Organization's Quality of Life questionnaire. The improvement group transitioned from not having subjective well-being during the baseline survey to having subjective well-being during the follow-up survey. Furthermore, we used multivariable log-Poisson regression models to calculate the prevalence ratios of subjective well-being. RESULTS: The cross-sectional study showed that sleep satisfaction, health services access satisfaction and having a higher-level functional capacity were positively associated with having "happiness" and "satisfaction with life." Furthermore, being aged ≥ 80 years and having financial leeway were positively associated with having "meaning in life." The longitudinal study showed that having a higher-level functional capacity was positively associated with improving "happiness" and "satisfaction with life." Being female was positively associated with improving "happiness" and "meaning in life," and health services access satisfaction and alcohol drinking were positively associated with improving "satisfaction with life" and "meaning in life," respectively. CONCLUSIONS: These findings offer promising avenues for enhancing the subjective well-being of older adults. Geriatr Gerontol Int 2024; 24: 311-319.

Older participants identified as having decreased physical activity according to the Japanese version of the Cardiovascular Health Study criteria did not show a significant reduction in accelerometer-measured physical activity. Despite its widespread use in Japanese studies, the Japanese version of the Cardiovascular Health Study physical activity questionnaire may not effectively capture declines in physical activity.

BACKGROUND: The association between functional capacity and the subsequent risk of nutritional deterioration is yet to be understood. The purpose of this study was to elucidate the relationship between functional capacity, comprising instrumental activities of daily living (IADL), intellectual activity, and social function, and future decline in nutritional status. METHODS: The current study is a two-year prospective cohort study. A total of 468 community-dwelling older adults without nutritional risks were enrolled. We used the Mini Nutritional Assessment Screening Form. Functional capacity, including IADL, intellectual activity, and social function, was assessed using the Tokyo Metropolitan Institute of Gerontology Index of Competence at baseline. The nutritional status was reassessed at a 2-year follow-up. Risk ratios (RR) of functional capacity for the incidence of nutritional decline were estimated. RESULTS: Low functional capacity was significantly associated with future deterioration of nutritional status (RR 1.12, 95% confidence interval [CI] 1.02-1.25). Of the subdomains of functional capacity, IADL decline (adjusted RR 2.21, 95% CI 1.18-4.13) was an independent risk factor for the incidence of nutritional risk. Intellectual and social activities were not significant. CONCLUSION: Decline in functional capacity, especially IADL, is a risk factor for future deterioration in nutritional status. Further studies are required to elucidate the effect of interventions for IADL decline on maintaining nutritional status in older adults.

Purpose: This study aimed to evaluate the relationship between timed up-and-go (TUG) test time and changes in frailty status in a longitudinal cohort study of rural Japanese older adults. Patients and Methods: This prospective cohort study included 545 community-dwelling older adults. Initial and 2-year follow-up surveys were conducted. We compared the number of the Japanese version of the Cardiovascular Health Study components during the follow-up period and classified the participants into three groups: the favorable change, unchanged as prefrail, and unfavorable change groups. Associations between changes in frailty status and TUG time in the first survey were examined. The predictive ability of the TUG test was determined using the receiver operating characteristic (ROC) curve. Results: The favorable change group comprised 315 individuals (57.8%), the unchanged as prefrail group 105 (19.2%), and the unfavorable change group 125 (22.9%). TUG time was associated with the favorable and unfavorable changes after adjustment for covariates (OR 0.79, 95% CI 0.68-0.92, P=0.001 and OR 1.27, 95% CI 1.09-1.49, P=0.002). The ROC curve of TUG time as a predictor of unfavorable changes showed an area under the curve of 0.59. A cut-off point of TUG was calculated as 6.3 s with 49.6% sensitivity and 66.0% specificity. Conclusion: TUG time in the first survey was significantly associated with changes in frailty status 2 years later. However, its predictive value as a stand-alone test is limited and has the potential to predict future changes in the frailty status in older adults in combination with other tests.

BACKGROUND: Patients who undergo total hip arthroplasty have an increased risk of falls during the first postoperative year. However, it is unclear whether patients after total hip arthroplasty will continue to be at high risk of falls more than 1 year postoperatively. To better understand whether the risk of falls changes after a 1-year period, we investigated the incidences and circumstances of falls in women patients for 5 years after total hip arthroplasty. METHODS: This longitudinal prospective cohort study analyzed 65 women with severe hip osteoarthritis who underwent total hip arthroplasty. The incidences and circumstances of falls before total hip arthroplasty and at 1, 2, and 5 years postoperatively were investigated. We assessed the Harris Hip Score and evaluated hip pain and ambulatory ability using a self-administered questionnaire. RESULTS: The incidences of at least one fall were 30.8%, 26.2%, 23.1%, and 30.8% before and 1, 2, and 5 years after surgery, respectively. Among the circumstances of falls from pre-surgery to 5 years post-surgery, there was a significant difference in the direction of falls; however, there were no significant differences in the location, time, cause, and type of injury. Most falls occurred indoors by tripping or loss of balance during the daytime. Among the participants who had falls almost half sustained injuries, and approximately 10% of falls resulted in fractures each year. Although self-reported hip pain, ambulation, and the Harris Hip Score significantly improved in women after total hip arthroplasty compared to pre-surgery, there was no significant difference in the incidences of falls from 1 to 5 years post-surgery. CONCLUSION: Women who underwent total hip arthroplasty continued to have an increased risk of falls and fall-induced injuries for 5 years postoperatively. Preventive measures against falling to reduce fall-induced injuries in the long term are required for women after total hip arthroplasty.

AIM: To determine the association between physical activity and apathy in community-dwelling older adults. METHODS: This was a cross-sectional study. Apathy was assessed using three sub-items from the Geriatric Depression Scale 15 (GDS-3A) on apathy syndrome. Physical activity was measured using a wrist-worn accelerometer. Exercise intensity was classified as sedentary behavior, light-intensity physical activity, or moderate-to-vigorous-intensity physical activity. A logistic regression analysis was used to examine the association between apathy and physical activity for each exercise intensity level. RESULTS: Seven-hundred and eighty-four participants (age 72.7±5.9 years old) were included. Of those, 103 (13.1%) were in the apathy group. A multivariate analysis adjusted for demographic factors revealed that decreased total physical activity (odds ratio [OR] = 0.947, 95% confidence interval [CI] = 0.912-0.984, p = 0.005), light-intensity physical activity (OR = 0.941, 95% CI = 0.899-0.985, p = 0.009), and increased sedentary behavior (OR = 1.002, 95% CI = 1.001-1.003, p = 0.007) were associated with a greater OR of apathy, although moderate-to-vigorous-intensity physical activity was not significant (OR = 0.916, 95% CI = 1.826-1.017, p = 0.100). However, in the final model adjusted for depressive symptoms and functional factors, the association was not found to be significant, and a strong association was observed between depressive symptoms and apathy. CONCLUSION: Physical activity in older adults with apathy symptoms was decreased in this study. However, the associations seemed to be strongly affected by depressive symptoms, and physical activity was not independently associated with apathy.

OBJECTIVES: We aimed to clarify the factors that contribute to the improvement or progression of frailty in rural Japanese community-dwelling older adults. METHODS: Of the 840 participants in the cohort study of independent older adults aged 65 years and older living in the Tamba-Sasayama area of Hyogo Prefecture (FESTA study) from September 2016 to December 2017, 551 participated in the 2-year follow-up survey from September 2018 to December 2019. METHODS: We evaluated clinical background, physical and cognitive function, total physical activity, daily protein intake, quality of life (QOL) using the WHOQOL-BREF (WHOQOL-26), and frailty status diagnosed using the Japanese version of the Cardiovascular Health Study. We compared the frailty status at the initial and follow-up examinations and classified the participants into three groups: improvement, unchanged, and worsening. Each parameter was compared among the three groups and the factors contributing to the improvement or worsening of frailty status were analyzed using a modified Poisson regression analysis. RESULTS: The median age at the first survey was 72 years (range: 68-76); 190 men and 361 women were enrolled. The improvement group consisted of individuals with a change in status from frail to prefrail/robust and from prefrail to robust (n = 114); the worsening group consisted of individuals with a change in status from robust to prefrail/frail and from prefrail to frail (n = 92). The physical domain of QOL was significantly associated with an improvement in frailty status independent of the frailty status at baseline. Contrastingly, any domains of QOL were not significantly associated with a worsening frailty status. CONCLUSIONS: This study demonstrated for the first time that QOL has a significant impact on the future improvement and progression of frailty status and that QOL conditions and frailty status affect older adults bidirectionally.

BACKGROUND: Sarcopenia is prevalent in patients with chronic kidney disease (CKD), which is defined as a low estimated glomerular filtration rate (eGFR). It has been reported that oral hypofunction characterized by decreased tongue pressure is related to sarcopenia. Although there are several previous reports regarding the association of renal dysfunction with oral hypofunction characterized by low tongue pressure, the association between tongue pressure and renal function is not fully understood. METHODS: This cross-sectional study included 68 men aged 79.0 ± 4.8 years and 145 women aged 77.3 ± 5.4 years from a rural area in Hyogo Prefecture, Japan. We examined the relationships between cystatin C-based CKD (CKDcys), creatinine-based CKD (CKDcre), ratio of cystatin C-based GFR (eGFRcys) divided by creatinine-based GFR (eGFRcre): eGFRcys/eGFRcre, and tongue pressure in community-dwelling older adults. RESULTS: Tongue pressure was significantly lower in participants with CKDcys than in those without CKDcys in men and women. However, there were no significant differences in tongue pressure with or without CKDcre. Tongue pressure was significantly lower in participants with eGFRcys/eGFRcre <1.0, than in those with eGFRcys/eGFRcre ⧠1.0 in men. According to the receiver operating characteristic analysis, the optimal cut-off value of tongue pressure for the presence of CKDcys was 36.6kPa, area under the curve (AUC) 0.74 (specificity 54.8%, sensitivity 84.6%) in men and 31.8kPa, AUC 0.65 (specificity 67.3%, sensitivity 60.5%) in women. CONCLUSIONS: CKDcys but not CKDcre is associated with low tongue pressure. In addition, a lower eGFRcys/eGFRcre ratio is a useful screening marker of low tongue pressure in community-dwelling older adults.

In the assessment of skeletal muscle strength, rate of force development (RFD) is clinically identified as a functional index that reflects the effects of aging, but there are few reports on RFD of the tongue. The purpose of this study was to examine the relationship between RFD of tongue pressure (RFD-TP) and oral and whole-body physical performance in older adults, and to clarify its characteristics. We enrolled adults aged ≥65 years with pathological occlusal contact in premolar and molar regions of teeth in the Tamba-Sasayama area, Japan, from 2017 to 2018. Maximum tongue pressure (MTP) and the speed to reach the maximum tongue pressure (RFD-TP) were evaluated as measures of tongue function. Oral functions related to objective measures of tongue function, such as repetitive saliva swallowing test, oral diadochokinesis, and physical status or performance, such as mini mental state examination, body mass index, skeletal mass index, knee extension force, one-leg standing time, grip strength, walking speed, timed up-and-go test, and five-time chair stand speed was evaluated. No significant correlation was found between MTP and age, but RFD-TP had a significant negative correlation with age. Neither RFD-TP nor MTP showed a significant correlation with oral function. RFD-TP was associated with physical performance, such as knee extension force and one-leg standing time. RFD-TP is more sensitive to aging than MTP. In addition, RFD-TP is related to physical performance and may be useful for the early detection of frailty.
RESUMEN
OBJECTIVES: Sarcopenia is defined as a combination of low skeletal muscle mass index (SMI), weak muscle strength, and reduced physical function. Recently, many studies have reported that the creatinine/cystatin C ratio (Cr/CysC) is useful for evaluating muscle mass. We designed a cross-sectional study with separate model development and validation groups to develop a prediction equation to estimate bioimpedance analysis (BIA)-measured SMI with Cr/CysC. DESIGN: The current study was a retrospective cross-sectional study. SETTING AND PARTICIPANTS: The model development group included 908 subjects (288 men and 620 women) from the Frail Elderly in the Sasayama-Tamba Area (FESTA) study, and the validation group included 263 subjects (112 men and 151 women) from participants in the medical checkup program at the Anti-Aging Center in Ehime Prefecture. MEASURES: Multivariate regression analysis indicated that age, hemoglobin (Hb), body weight (BW), and Cr/CysC were independently associated with SMI in both men and women. The SMI prediction equation was developed as follows: Men:4.17-0.012×Age+1.24×(Cr/CysC)-0.0513×Hb+0.0598×BW Women:3.55-0.00765×Age+0.852×(Cr/CysC)-0.0627×Hb+0.0614×BW RESULTS: The SMI prediction equation was applied to the validation group and strong correlations were observed between the BIA-measured and predicted SMI (pSMI) in men and women. According to the receiver operator characteristic (ROC) analysis, the areas under the curve were 0.93 (specificity 89.0%, sensitivity 87.2%) among men and 0.88 (specificity 83.6%, sensitivity 79.6%) among women for using pSMI to identify low SMI in the model development group. The pSMI also indicated high accuracy in ROC analysis for low SMI in the validation group. The Bland-Altman plot regression showed good agreement between BIA-measured and pSMI. CONCLUSIONS AND IMPLICATIONS: Our new prediction equation to estimate SMI is easy to calculate in daily clinical practice and would be useful for diagnosing sarcopenia.

BACKGROUND: Foam rolling is a self-applied massage using a foam roller that has gained popularity for treatment of muscle soreness. However, its efficacy for improving hip pain in patients with hip osteoarthritis remains unclear. OBJECTIVE: To investigate the effects of foam rolling on hip pain in patients with hip osteoarthritis. METHODS: In this retrospective propensity-matched cohort study, medical records of outpatients between January 2017 and March 2019 were reviewed. Of these, 115 patients with hip osteoarthritis were divided into foam rolling or non-foam rolling groups based on home exercises. Both groups were propensity-score matched (1:1) for age, sex, body mass index, Kellgren and Lawrence grade, and visual analog scale (VAS) of hip pain at baseline. The primary outcome was the hip pain-VAS. Effects of interventions on the hip pain-VAS were examined using a split-plot design variance analysis. RESULTS: After matching, both groups comprised 37 patients each. No significant differences were observed in baseline characteristics and outcome measurements between the matched groups. A statistically significant interaction was seen between the effects of time and group for hip pain-VAS (F [1, 72] = 31.874, interaction: P < .001, η2 = 0.307). Hip pain-VAS was improved more effectively in the foam rolling group than those in the non-foam rolling group (P < .001). Thirty-four (92%) patients in the foam rolling group, compared to 15 (41%) in the non-foam rolling group, showed a ≥ 32% (minimal clinically important difference) improvement in hip pain-VAS. CONCLUSION: These results suggested that foam rolling was an effective intervention for improving hip pain in patients with hip osteoarthritis.

BACKGROUND: Falls among older adults with a low bone density can lead to a bedridden state. Declining bone density increases the risk of falls resulting fractures in older adults. A person's physical performance is known to be closely related to bone density, and a relationship between the physical performance and the oral function is also known to exist. However, there currently is a lack of evidence regarding the relationship between bone density and the oral function. We assessed the relationship between the bone density and the both the oral function and physical performance among older adults. PATIENTS AND METHODS: 754 older adults aged 65 years or older who independently lived in rural regions and who were not taking any medications for osteoporosis participated. We checked all participants for osteoporosis using an ultrasonic bone density measuring device. Regarding the oral function, we evaluated the following factors: remaining teeth, occlusal support, masticatory performance, occlusal force, and tongue pressure. We also evaluated body mass index (BMI) and skeletal muscle mass Index as clinical characteristics. The normal walking speed, knee extension force and one-leg standing test were evaluated as physical performance. For the statistical analyses, we used the Mann-Whitney U test, chi-square test, the Kruskal-Wallis, and a multiple regression analysis. RESULTS: Eighty-one percent of the females and 58% of the males had osteoporosis or a decreased bone mass. The occlusal force, masticatory performance and the tongue pressure showed significant association with the bone density. The participants physical performance showed a significant association with their bone states except for walking speed. According to a multiple regression analysis, clinical characteristics (sex, age, BMI), one-leg standing and occlusal force showed independent associations with the bone density. It was suggested that the bone density tends to increase if the occlusal force is high and/or the one-leg standing test results are good. CONCLUSIONS: The bone density in the older adults showed a significant relationship not only with clinical characteristics or physical performance, but also with occlusal force. It may also be effective to confirm a good oral function in order to maintain healthy living for older adults.

This cross-sectional study aimed to demonstrate the association between physical frailty subdomains and oral frailty. This study involved community-dwelling older adults (aged ≥65 years). Physical frailty was assessed with the Japanese version of the Cardiovascular Health Study criteria. Oral frailty was defined as limitations in at least three of six domains. Logistic regression analysis was used to analyze the association between physical frailty risk and oral frailty. In addition, we examined the association between physical frailty subdomains (gait speed, grip strength, exhaustion, low physical activity, and weight loss) and oral frailty. A total of 380 participants were recruited for this study. Overall, 18% and 14% of the participants were at risk of physical frailty and had oral frailty, respectively. Physical frailty risk (odds ratio (OR) = 2.40, 95% confidence interval (CI): 1.22-4.75, p = 0.012) was associated with oral frailty in multivariate analysis. In secondary analysis, among physical frailty subdomains, gait speed (OR = 0.85, 95% CI: 0.73-0.97, p = 0.019) was associated with oral frailty. The present findings suggest that physical frailty is closely related to oral frailty. Among physical frailty subdomains, decreased gait speed in particular is an important indicator related to the development of oral frailty.

BACKGROUND: Sarcopenia is prevalent in patients with chronic kidney disease (CKD). The indices of physical function, such as grip power and gait speed, decreased according to the decline in the estimated glomerular filtration rate (eGFR). METHODS: We examined the relationships between cystatin C-based GFR (eGFRcys), creatinine-based GFR (eGFRcre), their ratio (eGFRcys/eGFRcre) and sarcopenia in community-dwelling older adults in Japan. This cross-sectional study included 302 men aged 73.9 ± 6.2 years and 647 women aged 72.9 ± 5.8 years from a rural area in Hyogo Prefecture, Japan. eGFRcys and eGFRcre were simultaneously measured, and sarcopenia based on the Asia Working Group for Sarcopenia (AWGS) 2019 criteria was evaluated. RESULTS: eGFRcys and the eGFRcys/eGFRcre ratio were significantly correlated with grip power and gait speed (p < 0.001). The eGFRcys/eGFRcre ratio was also correlated with skeletal muscle mass index (SMI) (p < 0.01). Univariate logistic regression analysis showed eGFRcys and eGFRcys/eGFRcre ratio but not eGFRcre were associated with sarcopenia (p < 0.01). The presence of low eGFRcys (CKDcys) and low eGFRcys/eGFRcre ratio (< 1.0) but not that of low eGFRcre (CKDcre) were associated with sarcopenia (p < 0.01). In the multivariate logistic regression analysis, when the eGFRcys/eGFRcre ratio was added as a covariate to the basic model, it was significantly associated with sarcopenia in women (p < 0.05). Moreover, low eGFRcys/eGFRcre ratio (< 1.0) was associated with a higher risk of sarcopenia in men (p < 0.01). CONCLUSION: In conclusion, CKDcys but not CKDcre is associated with sarcopenia. A lower eGFRcys/eGFRcre ratio may be a practical screening marker of sarcopenia in community-dwelling older adults.

AIM: We speculated that low back pain, which is the most common ailment in older adults, is associated with frailty and/or sarcopenia and contributes to the progression of either condition. Our objective was to evaluate the relationship between low back pain, sarcopenia and frailty in rural Japanese community-dwelling older adults. METHODS: We recruited 730 participants aged ≥65 years who underwent a comprehensive health examination between November 2016 and December 2018. The Oswestry Disability Index (ODI) was used to assess low back pain quantitatively, and scores were compared for the frail groups determined by the Japanese version of Cardiovascular Health Study, and the sarcopenia groups as determined by the Asian Working Group for Sarcopenia 2019. RESULTS: Among 730 participants, the prevalence of low back pain was 57.8%. There were significant differences in the ODI scores between the robust, prefrail and frail groups (P < 0.001). In contrast, there were no significant differences in the ODI scores among the robust, low appendicular skeletal muscle and sarcopenia groups. Logistic regression analysis showed that the prevalence of low back pain and the ODI scores were significantly associated with frailty after adjustment for age, sex and body mass index (odds ratio 3.41, 95% confidence interval 1.39-8.39, P = 0.008, and odds ratio 1.06, 95% confidence interval 1.04-1.09, P < 0.001, respectively). CONCLUSIONS: To the best of our knowledge, this study is the first to show the close association between low back pain and frailty, and suggests that not only the decline in physical function but also neuropsychiatric factors, including chronic pain, constitute a vicious cycle of frailty in community-dwelling older adults.

It is often assumed that oral hypofunction is associated with social withdrawal in older adults because decreased motor function is related to decreased oral function. However, few studies have examined the relationship between social withdrawal in older adults and oral function. This longitudinal study aimed to clarify the relationship between changes in the level of social withdrawal and oral function in independent older adults. Participants were 427 older adults aged 65 years or older who took part in a self-administered questionnaire from 2016 to 2017 (baseline), and again two years later (follow-up). At baseline, 17 items related to oral function and confounding factors related to withdrawal, physical condition, physical function, and cognitive function were evaluated. A Cox proportional hazard model was used to examine the oral functions that negatively impact social withdrawal. The following factors were significantly associated with the worsening of social withdrawal: the number of remaining teeth, gingival condition, occlusal force, masticatory efficiency, and items related to swallowing and dry mouth. Older adults with cognitive issues who walk slowly and have a weak knee extension muscle were also significantly more likely to have oral frailty. Those who were found to have oral frailty at baseline were 1.8 times more likely to develop withdrawal compared to those with robust oral function. The results indicated that the worsening of withdrawal was associated with oral hypofunction at baseline. Since oral hypofunction was associated with the worsening of social withdrawal in older adults, it is important to maintain older adults' oral function.

BACKGROUND: It has not been clarified whether physical frailty symptoms predict social. frailty. The purpose of this study was to elucidate the effect of physical frailty on social frailty, and to determine which domains of physical frailty predict the development of social frailty. METHODS: We employed a two-year prospective cohort study. A total of 342 socially robust community-dwelling older adults were recruited. We used a modified social frailty screening index consisting of four social domains including financial difficulties, living alone, social activity, and contact with neighbors. Physical frailty status was also assessed at baseline. At the two-year follow-up, we assessed the development of social frailty. Social status was assessed using four social subdomains for the primary analysis. Social status was assessed using the two social subdomains of social activity and contact with neighbors, which would be affected by the physical frailty component, for the secondary analysis. The risk ratios (RR) of physical frailty for the development of social frailty were estimated. RESULTS: Although physical frailty symptoms were not a significant risk factor for future development of social frailty as assessed by four social subdomains (adjusted RR 1.39, 95% CI 0.95-2.15), it became significant when development of social frailty was assessed by the two social subdomains (adjusted RR 1.78, 95% CI 1.10-2.88). An analysis using the physical frailty subdomain showed that slow gait speed (adjusted RR 3.41, 95% CI 1.10-10.53) and weakness (adjusted RR 1.06, 95% CI 1.01-1.12) were independent risk factors for development of social frailty as assessed by two social subdomains. CONCLUSIONS: Physical frailty symptoms predict the development of social frailty. Among physical frailty subdomains, gait speed and muscle strength are critical independent risk factors for future decline in the social aspect. The prevention of physical frailty, especially by maintaining gait ability and muscle strength, may be effective for avoiding social frailty.
