AimThe Asian Working Group for Sarcopenia 2019 consensus reported that evidence for the diagnosis of sarcopenia based on ultrasonography findings is lacking. The revised European Working Group on Sarcopenia in Older People consensus stated that ultrasonography is reliable and valid for assessing muscle size in older adults. The present study aimed to determine the predictive accuracy of ultrasonography for sarcopenia in older adults in Japan.MethodsA total of 1229 participants aged 65–91 years were included in this cross‐sectional study. The thickness of the anterior compartment of the right thigh was assessed using B‐mode ultrasonography. The measurement position was at the midpoint of the thigh. In addition, the grip strength, gait speed, Five‐Time Sit‐to‐Stand Test, Short Physical Performance Battery score and skeletal muscle mass index were evaluated. Sarcopenia was diagnosed based on the Asian Working Group for Sarcopenia 2019 algorithm. We calculated the area under the receiver operating characteristic curve.ResultsThe area under the receiver operating characteristic curves (95% confidence intervals) and cutoff values for the thigh muscle thickness in sarcopenia were 0.901 (0.856–0.946) and 4.0 cm in men, respectively, and 0.923 (0.851–0.995) and 3.1 cm in women, respectively. The area under the receiver operating characteristic curve for each subdomain of sarcopenia, such as grip strength and gait speed, ranged from 0.618 to 0.872.ConclusionsIn the present study, the suggested cutoff mid‐thigh muscle thicknesses on ultrasonography for predicting sarcopenia were 4.0 cm in men and 3.1 cm in women.
