OBJECTIVE: Population-specific muscle mass cut-off values are recommended for the diagnosis of sarcopenia. In this study, we aimed to determine the appendicular muscle mass index (ASMI) and phase angle (PA) cut-off values for the Turkish population using multi-frequency bioelectrical impedance analysis (mBIA).
PATIENTS AND METHODS: A total of 250 healthy volunteers aged 18-40 years were included in the study between September 2020 and December 2021. PA was measured by mBIA, and appendicular skeletal muscle mass (ASM) was calculated by the Sergi formula using the resistance and reactance measurements from mBIA. ASMI was calculated as ASM (kg)/(height in meters)2. Two standard deviations (SD) below the mean values were accepted as cut-off points.
RESULTS: 134 women and 116 men were included in the study (26.0±5.6 years). The ASMI cut-offs for men and women were 5.86 and 4.36 kg/m2, respectively. The PA cut-offs were 5.66° in men and 4.38° in women.
CONCLUSIONS: The present study reported the ASMI and PA cut-off values specific to the Turkish population using the Sergi formula, which was suggested by the European Working Group on Sarcopenia in Older People (EWGSOP).
