Equation of Rangel Peniche et al for Estimating Appendicular Skeletal Muscle Mass of an Older Mexican Adult Using Bioelectrical Impedance Analysis (BIA)
Rangel Peniche et al reported a new equation for estimating appendicular skeletal muscle mass using bioelectrical impedance analysis (BIA). The authors are from Licenciatura y Maestria en Nutricion and Centro de Investigacion en Alimentacion y Desarrollo in Mexico.
Patient selection: adult Mexicans > 60 years old
