Currently, sarcopenia has been recognized as a specific disease rather than normal
aging process because of its close relationship with multiple adverse outcomes in
older people.

The diagnosis of sarcopenia requires measurements of appendicular skeletal muscle
mass (ASM) plus muscle strength and physical performance.

Nevertheless, it is never convenient to conduct a community-based screening program
for sarcopenia based on the dual-energy X-ray absorptiometry or body impedance analysis.
Although SARC-F questionnaire has been developed and validated in screening sarcopenia
in community or clinical settings,

an accurate estimation of ASM may help promoting awareness for sarcopenia in the
general public. Calf circumference has been reported as a screening tool for low skeletal
muscle mass in older Turkish population.

Therefore, we conducted a cross-sectional analysis of data from the I-Lan Longitudinal
Aging Study, comprising of 1839 community-dwelling participants aged 50 years and
over,

to explore the potential to identify an accurate estimation of low ASM by calf circumference.To read this article in full you will need to make a payment
