Role of Ultrasonography in Estimating Muscle Mass in Sarcopenic Obesity

BACKGROUND Sarcopenic obesity (SO) is the coexistence of sarcopenia and obesity in an individual. The present study is designed to define the usefulness of skeletal muscle ultrasonography (US) in the definition of SO. METHODS Eighty-nine participants aged ≥65 whose body mass index (BMI, kg/m2 ) was ≥30 were consecutively enrolled in an outpatient clinic of geriatric medicine. All underwent comprehensive geriatric assessment. US measurements were obtained in 6 different muscles consisting of core and limb muscles. We defined SO as the presence of low muscle function (defined by a handgrip strength < 27 kg in males and
