The aim of this study was to evaluate the diagnostic value of the sarcopenia index (serum creatinine [mg/dl]/cystatin C [mg/dl]× 100) for estimating low muscle mass and sarcopenia in community-dwelling older adults. We included 371 older adults (≥ 60 years) with normal kidney function. Four common diagnostic criteria (the European Working Group on Sarcopenia in Older People (EWGSOP), Asia Working Group for Sarcopenia (AWGS), International Working Group on Sarcopenia (IWGS), and Foundation for the National …

Objectives To assess whether frailty is a risk factor for skeletal muscle mass decline in community‐dwelling elderly people. Design Prospective observational cohort study. Setting Seongnam, Gyeongi Province, Korea. Participants Community‐dwelling Koreans aged 65 and older (n= 341). Measurements Bioimpedance analysis (BIA) was used to measure body composition at baseline and 5 years later. Laboratory examination and comprehensive geriatric assessment were performed at both times. Lean mass index (LMI) was defined as …

Objectives Sarcopenic dysphagia is partly characterized by a decline in the strength of the swallowing muscles. However, its associated characteristics and symptoms are unclear. The aim of this study was to clarify the characteristics and symptoms of swallowing ability associated with low tongue muscle strength, which is one of the swallowing muscles in older adults. Methods This was a cross-sectional study of 197 older patients admitted to the hospital for orthopedic conditions. We measured the maximum tongue pressure (MTP) …

BACKGROUND/AIMSA U-shaped relationship between body mass index (BMI) and mortality has been reported. However, controversy exists as to whether skeletal muscle mass affects mortality in healthy older adults. We evaluated the independent association of BMI or appendicular skeletal muscle mass (ASM) with mortality in elderly people. METHODS A total of 4,261 consecutive subjects older than 65 years who underwent health examinations at Seoul National University Gangnam Center between 2005 and 2009 were …

Background Sarcopenia is prevalent in patients with chronic kidney disease and is associated with increased mortality; however, limited data are available on whether kidney transplantation can improve muscle wasting. Therefore, the present study aimed to assess changes in body composition before and after kidney transplantation. Methods Between April 2015 and January 2018, 80 de novo consecutive adult patients with end-stage kidney disease who underwent kidney transplantation were prospectively enrolled. Muscle and fat …

Background Declines in muscle mass and function are inevitable developments of the advanced aging process. Corresponding dimensions of longitudinal changes in at-risk populations are still scarce although clinically relevant. The present study monitored changes in morphologic and functional sarcopenia criteria related to sarcopenia in older men with low muscle mass over a period of 24 months. Objectives The main objective of the present study was to determine whether changes in muscle mass and function were …

Aim We developed a simple self‐screening method, the “Yubi‐wakka (finger‐ring)” test to assess sarcopenia swiftly. This prospective cohort study aimed to examine the validity of this test as a practical method among community‐dwelling older adults for identifying sarcopenia, and for predicting disability and mortality. Methods We followed 1904 older adults, and analyzed associations between this “Yubi‐wakka” test result at baseline in 2012 and sarcopenia at baseline, new‐onset sarcopenia followed until 2014, and new …

Considerably decreased muscle mass and function are subsumed under “sarcopenia”, a geriatric syndrome. Dedicated exercise programs maintain muscle mass and function; however, due to the limited enthusiasm of older adults to exercise, it is important to generate low-threshold interventions for this vulnerable cohort. Thus, the primary aim of this study was to determine the effect of low volume/high intensity resistance exercise training (HIT-RT) combined with protein supplementation on body composition and strength in older men with …

Background Sarcopenia and osteoporosis reduce life quality and worsen prognosis in patients with liver cirrhosis (LC). When these two complications coexist, a diagnosis of osteosarcopenia is made. We aimed to investigate the actual situations of sarcopenia, osteoporosis, osteosarcopenia, and vertebral fracture, and to clarify the relationship among these events in patients with LC. Methods We describe a cross-sectional study of 142 patients with LC. Sarcopenia was defined according to the Japan Society of Hepatology …

Background Although sarcopenia and frailty are important diseases in geriatrics, few studies have investigated the association between the two diseases. Thus, this study aimed to examine the relationship between two components of sarcopenia (muscle mass and muscle function) and frailty. Methods In total, 997 Korean older adults (456 men and 541 women) were included in this cross‐sectional observational study. We used a polynomial linear regression analysis to obtain standardized sex, age, and height‐adjusted appendicular …
