ObjectiveTo compare clinical characteristics of sarcopenia defined by the International Working Group on Sarcopenia (IWGS) and European Working Group on Sarcopenia in Older People (EWGSOP) criteria among older people in Taiwan. DesignA prospective population-based community study. SettingI-Lan County of Taiwan. ParticipantsA total of 100 young healthy volunteers and 408 elderly people. InterventionNone. MeasurementsAnthropometry, skeletal muscle mass measured by dual x-ray absorptiometry, relative appendicular skeletal muscle index (RASM), percentage skeletal muscle index (SMI), 6-meter walking speed, and handgrip strength. ResultsThe prevalence of sarcopenia was 5.8% to 14.9% in men and 4.1% to 16.6% in women according to IWGS and EWGSOP criteria by using RASM or SMI as the muscle mass indices. The agreement of sarcopenia diagnosed by IWGS and EWGSOP criteria was only fair by using either RASM or SMI (kappa = 0.448 by RASM, kappa = 0.471 by SMI). The prevalence of sarcopenia was lower by the IWGS definition than the EWGSOP definition, but it was remarkably lower by using RASM than SMI in both criteria. Overall, sarcopenic individuals defined by SMI were older, had a higher BMI but similar total skeletal muscle mass, and had poorer muscle strength and physical performance than nonsarcopenic individuals. However, by using RASM, sarcopenic individuals had less total skeletal muscle mass but similar BMI than nonsarcopenic individuals. Multivariable logistic regression showed that age was the strongest associative factor for sarcopenia in both IWGS and EWGSOP criteria. Obesity played a neutral role in sarcopenia when it is defined by using RASM, but significantly increased the risk of sarcopenia in both criteria by using SMI. ConclusionThe agreement of sarcopenia defined by IWGS and EWGSOP was only fair, and the prevalence varied largely by using different skeletal muscle mass indices. Proper selections for cutoff values of handgrip strength, walking speed, and skeletal muscle indices with full considerations of gender and ethnic differences were of critical importance to reach the universal diagnostic criteria for sarcopenia internationally. 相似文献

ObjectivesThe prevalence of obesity with sarcopenia is increasing in adults aged ≥65 years. This geriatric syndrome places individuals at risk for synergistic complications that leads to long-term functional decline. We ascertained the relationship between sarcopenic obesity and incident long-term impaired global cognitive function in a representative US population. DesignA longitudinal, secondary data set analysis using the National Health and Aging Trends Survey. SettingCommunity-based older adults in the United States. ParticipantsParticipants without baseline impaired cognitive function aged ≥65 years with grip strength and body mass index measures. MethodsSarcopenia was defined using the Foundation for the National Institutes of Health Sarcopenia Project grip strength cut points (men <35.5 kg; women <20 kg), and obesity was defined using standard body mass index (BMI) categories. Impaired global cognition was identified as impairment in the Alzheimer's Disease-8 score or immediate/delayed recall, orientation, clock-draw test, date/person recall. Proportional hazard models ascertained the risk of impaired cognitive function over 8 years (referent = neither obesity or sarcopenia). ResultsOf the 5822 participants (55.7% women), median age category was 75 to 80, and mean grip strength and BMI were 26.4 kg and 27.5 kg/m 2, respectively. Baseline prevalence of sarcopenic obesity was 12.9%, with an observed subset of 21.2% participants having impaired cognitive function at follow-up. Compared with those without sarcopenia or obesity, the risk of impaired cognitive function was no different in obesity alone [hazard ratio (HR) 0.98; 95% confidence interval (CI) 0.82–1.16]), but was significantly higher in sarcopenia (HR 1.60; 95% CI 1.42–1.80) and sarcopenic obesity (HR 1.20; 95% CI 1.03–1.40). There was no significant interaction term between sarcopenia and obesity. ConclusionsBoth sarcopenia and sarcopenic obesity are associated with an increased long-term risk of impaired cognitive function in older adults. 相似文献

Osteoporosis and sarcopenia are two chronic conditions, which widely affect older people and share common risk factors. We investigated the prevalence of low bone mineral density (BMD) and sarcopenia, including the overlap of both conditions (osteosarcopenia) in 572 older hospitalized patients (mean age 75.1 ± 10.8 years, 78% women) with known or suspected osteoporosis in this prospective observational multicenter study. Sarcopenia was assessed according to the revised definition of the European Working Group on Sarcopenia in Older People (EWGSOP2). Low BMD was defined according to the World Health Organization (WHO) recommendations as a T-score < −1.0. Osteosarcopenia was diagnosed when both low BMD and sarcopenia were present. Low BMD was prevalent in 76% and the prevalence of sarcopenia was 9%, with 90% of the sarcopenic patients showing the overlap of osteosarcopenia (8% of the entire population). Conversely, only few patients with low BMD demonstrated sarcopenia (11%). Osteosarcopenic patients were older and frailer and had lower BMI, fat, and muscle mass, handgrip strength, and T-score compared to nonosteosarcopenic patients. We conclude that osteosarcopenia is extremely common in sarcopenic subjects. Considering the increased risk of falls in patients with sarcopenia, they should always be evaluated for osteoporosis. 相似文献

ObjectiveSarcopenia is highly prevalent in hospitalized older patients and associated with short-term mortality. This study aimed to investigate whether sarcopenia and its measures handgrip strength (HGS) and muscle mass at hospital admission were associated with long-term mortality in a cohort of hospitalized older patients. DesignObservational, prospective, longitudinal inception cohort study. Setting and ParticipantsAcademic teaching hospital; patients age ≥70 years admitted to the internal medicine, acute admission, trauma, or orthopedic wards. MethodsHGS and muscle mass were measured at admission using a hand dynamometer and bioelectrical impedance analysis. Sarcopenia was determined based on the European Working Group on Sarcopenia in Older People definition. HGS and muscle mass (skeletal muscle mass index, appendicular lean mass, relative skeletal muscle mass) were expressed as sex-specific tertiles. The associations of sarcopenia, HGS, and muscle mass with mortality (during a follow-up of 3.4-4.1 years) were analyzed using Cox regression, adjusted for age, sex, comorbidity, and weight or height. Associations of HGS and muscle mass were stratified by sex. ResultsOut of 363 patients [mean age: 79.6 years (standard deviation: 6.4), 49.9% female] 49% died. Probable sarcopenia (prevalence of 53.7%) and sarcopenia (prevalence of 20.8%) were significantly associated with long-term mortality [hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.08?2.17 and 1.71 95% CI 1.12?2.61, respectively]. Low HGS, skeletal muscle mass index, and appendicular lean mass were associated with a higher mortality risk (lowest tertile vs highest tertile: HR 2.660, 95% CI 1.40?5.05; HR 1.95, 95% CI 1.06?3.58 and HR 1.99 (95% CI 1.12?3.53) in male patients. No statistically significant associations of relative muscle mass with mortality were found. Conclusions and ImplicationsSarcopenia and its measures (low HGS and low absolute muscle mass at admission) predict long-term mortality in older hospitalized patients. 相似文献

ObjectivesPrevious studies have indicated that sarcopenic obesity is a risk factor for disability onset. However, these studies had disparities in terms of criteria for sarcopenia, study design, or study population. No longitudinal study has investigated the effect of sarcopenic obesity on disability onset in an Asian population using the Asian Working Group for Sarcopenia 2019 criteria for sarcopenia definition. Herein, we aimed to investigate the longitudinal effect of sarcopenic obesity on disability onset in Japanese older adults and extend the generalizability of results to other populations. DesignLongitudinal cohort study. Setting and ParticipantsA total of 4197 Japanese older adults (mean age 74.6 ± 5.0 years, 54.2% women) formed our study population. MeasurementsSarcopenia was identified using the Asian Working Group for Sarcopenia 2019 algorithm. Obesity was determined when body fat percentage was ≥25%, or when visceral fat content was ≥100 cm 2 for either sex. Disability onset was defined as a new case of long-term care insurance system certification for 5 years from baseline. Missing values were managed with multi-imputation. Cox proportional hazard regression analysis was used with disability onset as dependent variable and group (nonsarcopenia/nonobesity as a reference, nonsarcopenia/obesity, sarcopenia/non-obesity, possible sarcopenia/obesity, possible sarcopenia/non-obesity, sarcopenic obesity) as explanatory variable, and was adjusted for potential confounding factors. ResultsWhen the nonsarcopenia/nonobesity group was used as the reference category, other groups such as possible-sarcopenia/nonobesity [hazard ratio (HR) 1.38, 95% confidential interval (95% CI) 1.29‒1.47, P < .028], possible-sarcopenia/obesity (HR 1.54, 95% CI 1.46‒1.62 P < .001), sarcopenia/nonobesity (HR 2.09, 95% CI 1.96‒2.23, P < .001), and sarcopenic obesity (HR 2.48, 95% CI 2.24‒2.75, P < .001) showed significantly increased HRs. Conclusions and ImplicationsThe risk of disability onset because of sarcopenic obesity was exceedingly higher compared with sarcopenia alone among community-dwelling older adults in Japan The health providers should consider assessing the co-existence of sarcopenia and obesity to screen for the risk of disability onset in the community-dwelling population. 相似文献

ObjectivesOlder adults with sarcopenic obesity have a higher risk of experiencing mobility difficulty. Additionally, sarcopenia and obesity are closely associated with knee osteoarthritis. This study investigated the associations of sarcopenia, obesity, and in combination of both with walking disability during postoperative rehabilitation in older adults with knee osteoarthritis who underwent total knee replacement. DesignA retrospective cohort study. Setting and ParticipantsFrom a rehabilitation center database, we retrospectively selected and investigated 482 older patients with knee osteoarthritis who had undergone total knee replacement and received postoperative rehabilitation. MethodsSarcopenia was identified in accordance with the diagnostic criteria established by the Asian Working Group for Sarcopenia and obesity was defined as body mass index ≥ 30 kg/m 2. Accordingly, patients were classified into four body composition groups, namely sarcopenic obese, sarcopenic, obese, and normal (reference group). After total knee replacement, all patients attended monthly follow-up admission during the postoperative rehabilitation. Gait speed was measured before surgery and monthly after total knee replacement. A gait speed cutoff of 1.0 m/s was used to identify postoperative walking disability. Kaplan–Meier curve analysis was performed to measure the probability of experiencing postoperative walking disability among the groups. Cox multivariate regression models were established to calculate the hazard ratios of postoperative walking disability. ResultsCompared with the reference group, the sarcopenic, obese, and sarcopenic obese groups appeared to have a higher probability of experiencing postoperative walking disability (all P < .001). The sarcopenic obese group were likely to have the highest risk of experiencing postoperative walking disability (adjusted hazard ratio = 3.89). Conclusions and ImplicationsSarcopenia or obesity alone may independently exert negative effects on postoperative gait speed. The participants with sarcopenic obesity were likely to have the highest risk of experiencing walking disability following total knee replacement. The findings may serve as a reference for clinicians developing rehabilitation strategies to optimize walking ability after total knee replacement, especially those preoperatively diagnosed as having sarcopenic obesity. 相似文献

Loss of muscle mass and waning in muscle strength are common in older adults, and inflammation may play a key role in pathogenesis. This study aimed to examine associations of C-reactive protein (CRP) and systemic immune-inflammation index (SII) with sarcopenia and sarcopenic obesity in older adults with chronic comorbidities. Cross-sectional data from the National Health and Nutrition Examination Survey (1999–2006) were obtained for participants aged ≥60 years. Sarcopenia was defined by a lean mass and body height (males < 7.26 kg/m 2, females < 5.45 kg/m 2). Sarcopenic obesity was defined by the concurrent presence of sarcopenia and obesity (defined by relative fat mass). Logistic regression was used to assess the associations of CRP and SII with sarcopenia and sarcopenic obesity. The dose–response relationship was examined via restricted cubic splines. Of the participants ( n = 2483), 23.1% ( n = 574) and 7.7% ( n = 190) had sarcopenia and sarcopenic obesity, respectively. The multivariable logistic regression models suggested a positive association of SII with sarcopenia and sarcopenic obesity, but a positive statistically significant association was not consistently observed for CRP. Dose–response curves suggested similar association patterns for these biomarkers. In clinical practice, measures to prevent sarcopenia and sarcopenic obesity are needed for older vulnerable people with high systemic inflammation. 相似文献

Sarcopenia, defined as the loss of muscle mass, strength, and function with aging, is a geriatric syndrome with important implications for patients and healthcare systems. Sarcopenia increases the risk of clinical decompensation when faced with physiological stressors and increases vulnerability, termed frailty. Sarcopenia develops due to inflammatory, hormonal, and myocellular changes in response to physiological and pathological aging, which promote progressive gains in fat mass and loss of lean mass and muscle strength. Progression of these pathophysiological changes can lead to sarcopenic obesity and physical frailty. These syndromes independently increase the risk of adverse patient outcomes including hospitalizations, long-term care placement, mortality, and decreased quality of life. This risk increases substantially when these syndromes co-exist. While there is evidence suggesting that the progression of sarcopenia, sarcopenic obesity, and frailty can be slowed or reversed, the adoption of broad-based screening or interventions has been slow to implement. Factors contributing to slow implementation include the lack of cost-effective, timely bedside diagnostics and interventions that target fundamental biological processes. This paper describes how clinical, radiographic, and biological data can be used to evaluate older adults with sarcopenia and sarcopenic obesity and to further the understanding of the mechanisms leading to declines in physical function and frailty. 相似文献

BackgroundSarcopenia, the age-dependent loss of skeletal muscle mass, is highly prevalent among older adults in many countries; however, the prevalence of sarcopenia in healthy Japanese community-dwelling older adults is not well characterized. ObjectiveThe aim of this study was to evaluate the prevalence of sarcopenia and to examine the association of sarcopenia with falls and fear of falling in community-dwelling Japanese older adults. DesignThis is a cross-sectional study. Setting and SubjectsHealthy men (568) and women (1314) aged 65 to 89 years participated in this research. MeasurementsFor all participants, 3 measurements were taken: skeletal muscle mass measurement using bioelectrical impedance, 10 m at a usual walking speed, and handgrip strength. Sarcopenia was defined as the presence of both poor muscle function (low physical performance or low muscle strength) and low muscle mass. ResultsThe prevalence of sarcopenia, determined using the European Working Group on Sarcopenia in Older People–suggested algorithm, in men and women aged 65 to 89 years was 21.8% and 22.1%, respectively. The prevalence of sarcopenia increased age-dependently, especially in those older than 75 years in both genders. In the young old, the prevalence of sarcopenia was higher in women than in men; however, in those older than 85 years, the prevalence of sarcopenia was lower in women than in men ( P < .05). In addition, fall incidents and fear of falling were more prevalent in sarcopenic older adults than in nonsarcopenic older adults ( P < .05). ConclusionsThese results suggest that sarcopenia is highly prevalent in community-dwelling Japanese older adults and is related to falls and fear of falling. 相似文献

IntroductionThis study aimed to estimate the prevalence of sarcopenic obesity (SO) and the association between cognitive impairment and SO in a cohort of elderly Chinese community-dwelling individuals. MethodsA total of 948 elderly Chinese community-dwelling individuals aged 60–92 years were recruited. The participants were categorized into the following four groups according to their sarcopenia and obesity status: sarcopenic obese, sarcopenic, obese and non-sarcopenic, and non-obese group. Sarcopenia was defined as appendicular skeletal muscle index of <7.0 kg/m2 in men and <5.7 kg/m2 in women; obesity was defined as values greater than the upper two quintiles for body fat percentage stratified by gender of the study population; cognitive impairment was measured using the Mini-Mental State Examination and defined as a score of <24. ResultsA total of 945 participants were included in the statistical analyses with a mean age of 68.76 ± 6.50 years. The prevalence of SO was 6.0% (7.3% in men and 4.8% in women). The sarcopenic obese (odds ratio [OR]: 2.550, 95% confidence interval [CI], 1.196-5.435) and obese (ORs: 2.141, 95% CI, 1.230-3.728) groups had significantly increased risk for cognitive impairment in fully adjusted model, respectively. ConclusionThe SO prevalence in elderly Chinese community-dwelling individuals was relatively low (6.0%). The present study suggested SO was independently associated with cognitive impairment. 相似文献

ObjectivesTo identify the dietary patterns among community-dwelling Japanese older adults and to explore the association between these patterns and sarcopenia. DesignCross-sectional study. SettingKashiwa city, Chiba prefecture, Japan. ParticipantsCommunity-dwelling older adults (n = 1241) aged 65 years and over who were not eligible for long-term care. MeasurementsDietary intake was assessed using the brief self-administered diet history questionnaire (BDHQ). Dietary patterns were identified using both principal component analysis and the score on the Japanese diet comprising soybeans and soybean products, fish, vegetables, pickles, mushroom, seaweeds, and fruits. Sarcopenia was defined by the Asian Working Group for Sarcopenia (AWGS) criteria. A binary logistic regression analysis was performed with sarcopenia status as the dependent variable after adjusting for economic status, living alone status, BMI, energy intake, multimorbidity, and physical activity. ResultsParticipants’ mean age was 74.6 years, and 52.1% were male. According to AWGS criteria, 5.1% had sarcopenia. Three dietary patterns were identified from the principal component analysis. Dietary pattern 1 (DP1), showed high loadings for fish, tofu, vegetables, and fruits which are similar to the side dishes in a typical Japanese diet. Dietary pattern 2 (DP2) had high factor loadings for fish, rice, and miso soup which are main dishes in a typical Japanese diet. Dietary pattern 3 (DP3) had a high factor loading for noodles. Men with the lowest tertile of DP1 score had a higher likelihood of being sarcopenic (Adjusted odds ratio (AOR) 3.67, 95% confidence interval (CI) 1.20?11.2). Women with the lowest tertile of DP2 score had a moderate likelihood of being sarcopenic (AOR 2.71, 95%CI 0.99?7.46). Low adherence to Japanese dietary pattern was associated with prevalence of sarcopenia in both genders. ConclusionAdherence to a dietary pattern high in foods characteristic of a Japanese diet including fish, soybean products, vegetables, and fruits was associated with low prevalence of sarcopenia in both genders. 相似文献

BackgroundThe prevalence of sarcopenia defined using the Asian Working Group for Sarcopenia (AWGS) criteria in Asian communities has not been fully addressed. Moreover, few studies have addressed the influence of sarcopenia on mortality. MethodsA total of 1,371 and 1,597 residents aged 65 years or older participated in health surveys in 2012 and 2017. Sarcopenia was determined using the AWGS definition. Factors associated with the presence of sarcopenia were assessed using a logistic regression model in participants in the 2012 survey. Subjects in the 2012 survey were followed-up prospectively for a median of 4.3 years. Mortality risk for subjects with sarcopenia was examined using the Cox proportional hazards model. ResultsThe crude prevalence of sarcopenia was 7.4% and 6.6% in participants at the 2012 and 2017 surveys, respectively; there was no significant difference between surveys ( P = 0.44). The prevalence of sarcopenia increased significantly with age in both sexes (both P for trend <0.001). Subjects with sarcopenia were more likely to exercise less regularly, to intake less total energy, and to exhibit a disability in activity of daily living than those without. The multivariable-adjusted hazard ratio for all-cause mortality was 2.20 (95% confidence interval, 1.25–3.85) in subjects with sarcopenia, compared to those without. ConclusionsApproximately 7% of older subjects had sarcopenia in a community-dwelling older Japanese population. Moreover, subjects with sarcopenia had an increased mortality risk. Our findings suggest that a public health strategy for sarcopenia is needed to extend healthy life expectancy.Key words: sarcopenia, Asian Working Group for Sarcopenia, prevalence, mortality 相似文献

Background and ObjectivesThere is little evidence in the literature about the possible relationship between sarcopenia and cognition in older adults. Our objective was to investigate the association between cognitive impairment and sarcopenia in older adults living in the community through a systematic review of published studies. Research Design and MethodsWe performed a systematic review with meta-analysis through Pubmed, LILACS, Scielo and Web of Science databases between March 1, 2001 and December 18, 2018. We included longitudinal and cross-sectional studies that evaluated sarcopenia and cognition as a primary objective. ResultsOf the 274 studies identified by the systematic review, 10 were included in qualitative analysis (total of 9,703 participants), and 6 were eligible for the meta-analysis (n = 7,045). Mean prevalence of sarcopenia was 10.5%. Cognitive impairment was observed in 269 participants with sarcopenia (40%), compared with 1,616 in non-sarcopenic participants (25.3%). Sarcopenia was significantly associated with cognitive impairment (pooled OR = 2.50, 95% CI = 1.26–4.92; p = 0.008). Heterogeneity across the studies was high and significant (I2 = 84%). Discussion and ImplicationsOur analyzes confirmed that sarcopenic older adults presented a higher prevalence of cognitive impairment. Sarcopenia may represent a risk factor for cognitive decline, but longitudinal studies are needed to explore causality. 相似文献

ObjectivesSarcopenia, age-related muscle wasting, is associated with increased morbidity and mortality in the affected individuals. The pathogenesis of sarcopenia is not yet fully understood. A multifactorial concept is currently favored. The reduced number of motor units as a potential mechanism of muscle mass loss is explored in the present study. DesignThis is a cross-sectional study. SettingThe participants were community-dwelling older adults. ParticipantsThe participants were sarcopenic (75) and nonsarcopenic (74) according to the criteria of the European Working Group on Sarcopenia in Older People aged 65 to 94 years. MeasurementsThe motor unit number index (MUNIX) of the hypothenar muscle was used to assess the number and size [motor unit size index (MUSIX)] of motor units. ResultsThe participants with pathologic MUNIX and MUSIX (n = 23) are significantly more frequently sarcopenic (n = 17, P = .029) than nonsarcopenic (n = 6). The participants with pathologic MUNIX and MUSIX (n = 23) had significantly less muscle mass than the nonsarcopenic controls ( P < .001). After adjusting for age and sex, only gait speed has shown no difference between the 2 groups. Pearson's correlation coefficient between MUSIX and the reciprocal value of MUNIX is 0.87 ( P < .001). ConclusionsSarcopenia induced by a small number of motoneurons can be identified by applying the MUNIX method to the hypothenar muscle. An enlargement of motor units because of motoneuron loss seems to preserve physical performance. 相似文献

(1) Sarcopenia is a progressive loss of skeletal muscle mass and strength. The aim of this study was to determine the association of sarcopenia, defined according to the Working Group on Sarcopenia in Older People (EWGSOP2) diagnostic criteria, with mortality at 24 months in very elderly hemodialysis patients. (2) A prospective study was conducted in 60 patients on chronic hemodialysis who were older than 75 years. Sarcopenia was diagnosed according to EWGSOP2 criteria. Additionally, clinical, anthropometric and analytical variables and body composition by bioimpedance were assessed. The date and cause of death were recorded during 2 years of follow-up. (3) Among study participants, 41 (68%) were men, the mean age 81.85 ± 5.58 years and the dialysis vintage was 49.88 ± 40.29 months. The prevalence of probable sarcopenia was 75% to 97%, depending on the criteria employed: confirmed sarcopenia ranged from 37 to 40%, and severe sarcopenia ranged from 18 to 37%. A total of 30 (50%) patients died over 24 months. Sarcopenia probability variables were not related to mortality. In contrast, sarcopenia confirmation (appendicular skeletal muscle mass, ASM) and severity (gait speed, GS) variables were associated with mortality. In multivariate analysis, the hazard ratio (95% confidence interval) for all-cause death was 3.03 (1.14–8.08, p = 0.028) for patients fulfilling ASM sarcopenia criteria and 3.29 (1.04–10.39, p = 0.042) for patients fulfilling GS sarcopenia criteria. (4) The diagnosis of sarcopenia by EWGSOP2 criteria is associated with an increased risk of all-cause death in elderly dialysis patients. Specifically, ASM and GS criteria could be used as mortality risk markers in elderly hemodialysis patients. Future studies should address whether the early diagnosis and treatment of sarcopenia improve outcomes. 相似文献

Background: The post-COVID-19 condition, defined as COVID-19-related signs and symptoms lasting at least 2 months and persisting more than 3 months after infection, appears now as a public health issue in terms of frequency and quality of life alterations. Nevertheless, few data are available concerning long term evolution of malnutrition and sarcopenia, which deserve further attention. Method: Sarcopenia was investigated prospectively, together with weight evolution, at admission and at 3 and 6 months after hospital discharge in 139 COVID-19 patients, using the European Working Group on Sarcopenia in Older People (EWGSOP2) criteria, associating both decreased muscle strength and muscle mass, assessed, respectively, with hand dynamometer and dual-energy X-ray absorptiometry. Results: Of the 139 patients, 22 presented with sarcopenia at 3 months; intensive care units (ICU) length of stay was the sole factor associated with sarcopenia after multivariate analysis. Although the entire group did not demonstrate significant weight change, weight decreased significantly in the sarcopenia group (Five and eight patients, showing, respectively, >5 or >10% weight decrease). Interestingly, at 6 months, 16 of the 22 patients recovered from sarcopenia and their weight returned toward baseline values. Conclusions: Sarcopenia and malnutrition are frequently observed in patients hospitalized for COVID-19, even 3 months after infection occurrence, but can largely be reversed at 6 months after discharge. Enhanced patient care is needed in sarcopenic patients, particularly during long stays in an ICU. 相似文献

ObjectivesTranslation, adaptation, and validation of the German version of the SARC-F for community-dwelling older adults in Germany. DesignCross-sectional. Setting and Participants117 community-dwelling outpatients with a mean age of 79.1 ± 5.2 years were included in the study; 94 (80.4%) of them were female. Sixty-three (53.8%) had a positive SARC-F score of ≥4 points. According to the definition of sarcopenia from the European Working Group on Sarcopenia in Older People (EWGSOP2), 8 patients (6.8%) were identified as sarcopenic and 57 (48.7%) as probable sarcopenic. MethodsAccording to EWGSOP2, probable sarcopenia was defined for patients with reduced hand grip strength (women: <16.0 kg; men: <27.0 kg) and/or impaired chair-rise time (both genders: >15 seconds). Patients with additional low skeletal muscle index were classified as sarcopenic (women: <5.5 kg/m 2; men: <7.0 kg/m 2). Translation and cultural adaption was composed of 7 different steps that were in general based on the guidelines put forward by the World Health Organization. Validation include test-retest and the inter-rater reliability (intraclass correlation coefficient) as well as internal consistency (Cronbach alpha). Furthermore, sensitivity, specificity, positive predictive value, and negative predictive value of the SARC-F were calculated. Receiver-operating characteristic analysis was performed to calculate the area under the curve. ResultsThe translated and culturally adapted version of the SARC-F for the German language has shown excellent inter-rater reliability and good test-retest reliability. The internal consistency is acceptable. Sensitivity (63%) and specificity (47%) for sarcopenia is low. For detecting patients with probable sarcopenia, the SARC-F in the German version has shown 75% sensitivity and 67% specificity. Conclusions and ImplicationsBecause of a low sensitivity for detecting sarcopenia but an acceptable sensitivity for identifying probable sarcopenia, the German version of the SARC-F is a suitable tool for case finding of probable sarcopenia. 相似文献

ObjectivesSarcopenia is frequently seen at older ages, with primary sarcopenia being associated with mitochondrial dysfunction or age-related decreases in sex hormones while other explanations include endocrine and neurodegenerative diseases. This study was planned and conducted to determine the relationship between malnutrition and sarcopenia in elderly Turkish community-dwellers. Material and methodsIn total, 173 community-dwelling elderly individuals were recruited from the capital city of Turkey. A questionnaire form was applied via face-to-face method and the MNA-SF and Barthel Index were administered. In addition, some anthropometric measurements were taken. ResultsBody mass ( P < 0.05) and body height ( P < 0.05) were higher in non-sarcopenic elderly individuals. Age was lower in non-sarcopenic elderly ( P < 0.05). In this study, while the prevalence of sarcopenia was 50.2% in the elderly, the prevalence of malnutrition risk was found to be 42.2%. MNA-score was found to be significantly lower in sarcopenic elderly individuals. There was a strong relationship between sarcopenia and malnutrition risk, but not with daily living activities. ConclusionThe prevalence of sarcopenia was much higher than prevalence of risk at malnutrition. In Turkey, there is no bioelectrical impedance analysis performed among such community-dwellers, so this is the first study not using BIA while screening for sarcopenia in elderly community-dwellers. This study suggests that current nutritional policies in Turkey should target elderly individuals living in communities to screen for nutritional status regularly and apply interventions quickly. In doing so, there is no need for expensive equipment. 相似文献

Objectives:We investigated the associations of sarcopenia-defined both in terms of muscle mass and muscle strength-and sarcopenic obesity with metabolic syndrome. Methods:Secondary data pertaining to 309 subjects (85 men and 224 women) were collected from participants in exercise programs at a health center in a suburban area. Muscle mass was measured using bioelectrical impedance analysis, and muscle strength was measured via handgrip strength. Sarcopenia based on muscle mass alone was defined as a weight-adjusted skeletal muscle mass index more than two standard deviations below the mean of a sex-specific young reference group (class II sarcopenia). Two cut-off values for low handgrip strength were used: the first criteria were <26 kg for men and <18 kg for women, and the second criteria were the lowest quintile of handgrip strength among the study subjects. Sarcopenic obesity was defined as the combination of class II sarcopenia and being in the two highest quintiles of total body fat percentage among the subjects. The associations of sarcopenia and sarcopenic obesity with metabolic syndrome were evaluated using logistic regression models. Results:The age-adjusted risk ratios (RRs) of metabolic syndrome being compared in people with or without sarcopenia defined in terms of muscle mass were 1.25 (95% confidence interval [CI], 1.06 to 1.47, p=0.008) in men and 1.12 (95% CI, 1.06 to 1.19, p<0.001) in women, which were found to be statistically significant relationships. The RRs of metabolic syndrome being compared in people with or without sarcopenic obesity were 1.31 in men (95% CI, 1.10 to 1.56, p=0.003) and 1.17 in women (95% CI, 1.10 to 1.25, p<0.001), which were likewise found to be statistically significant relationships. Conclusions:The associations of sarcopenia defined in terms of muscle mass and sarcopenic obesity with metabolic syndrome were statistically significant in both men and women. Therefore, sarcopenia and sarcopenic obesity must be considered as part of the community-based management of non-communicable diseases. 相似文献
