Skeletal Muscle Mass Indices in Healthy Young Mexican Adults Aged 20–40 Years: Implications for Diagnoses of Sarcopenia in the Elderly Population

Table 2

Sex-effect on the proposed cut-off points based on two standard deviations below the mean value of the ASMI and TBSMI derived from healthy young Mexican adults.

Variables	Men (𝑛=136)	Women (𝑛=80)	𝑃 value
ASMI, (kg/m^2)	5.86	4.72	0.0001
TBSMI, (kg/m^2)	6.63	5.22	0.0001

ASMI: appendicular skeletal muscle mass index; TBSMI: total-body skeletal muscle mass index.
