Performance of the SARC-F, SARC-CalF, and calf circumference for sarcopenia case finding in community-dwelling older adults

Abstract

Aim: To compare the performance of different case-finding tools (SARC-F, SARC-CalF, calf circumference (CC), and BMI-adjusted CC) for sarcopenia in community-dwelling older adults. Findings: CC was the best tool for sarcopenia case-finding. The best performance was found for CC cut-off point of ≤ 34 cm in women and ≤ 36 cm in men. Message: In clinical practice, measurement of CC is a simple, inexpensive, and reliable tool to identify individuals at risk for sarcopenia for further assessment.
