They also had a significantly lower appendicular skeletal muscle mass (ASM), ASM/H2, appendicular fat mass (AFM), trunk skeletal muscle mass (TSM), trunk fat mass (TFM), body mass index (BMI), grip strength and calf circumference than those of the non-sarcopenia group (P < 0.05), but there is little difference in gender, step speed, serum albumin, 25-OH-Vitamin D and 25-OH-Vitamin D3 between two groups. This evidence concerns the gene ALB and sarcopenia.
