We previously detected that ~50% of kidney transplant patients (KTPs) present sarcopenia using the first European Working Group on Sarcopenia in Older People (EWGSOP1) consensus. Our aim was to evaluate the agreement between the sarcopenia diagnosis using EWGSOP1 and the new consensus (EWGSOP2) in KTPs. A cross-sectional study was performed evaluating 127 KTPs. Total and appendicular muscle mass were estimated by bioelectrical impedance. Strength was evaluated by handgrip strength (HGS) and five times sit to stand (5STS). Functional capacity was evaluated by 4-m walk test and short physical performance battery. Sarcopenia was diagnosed by EWGSOP1 and EWGSOP2. The agreement between EWGSOP1 and EWGSOP2 (using HGS criteria for muscle strength) was fair (k = 0.341–0.402). Slight agreement was observed between EWGSOP1 and EWGSOP2 using 5STS criteria for muscle strength (k = 0.031–0.046). We conclude that EWGSOP2 definitions have a low agreement with EWGSOP1 in KTPs.

我们先前使用第一个欧洲老年人肌肉减少症工作组（EWGSOP1）的共识，检测到约50％的肾移植患者（KTP）存在肌肉减少症。我们的目的是评估使用EWGSOP1进行的肌肉减少症诊断与KTP中新的共识（EWGSOP2）之间的一致性。进行了一项横断面研究，评估了127个KTP。通过生物电阻抗估计总的和阑尾的肌肉质量。通过握力（HGS）评估强度，并坐五次站立（5STS）。通过4-m步行测试和短物理性能电池评估功能容量。肌肉减少症是由EWGSOP1和EWGSOP2诊断的。EWGSOP1和EWGSOP2之间的协议（使用针对肌肉力量的HGS标准）是公平的（k = 0.341–0.402）。EWGSOP1和EWGSOP2在使用5STS肌肉强度标准时观察到轻微的一致（k  = 0.031–0.046）。我们得出的结论是，在KTP中，EWGSOP2定义与EWGSOP1的一致性较低。
