Rolland et al reported an equation for estimating appendicular skeletal muscle mass for elderly French females. The authors are from Hopital La Grave-Casselardit in Toulouse.
Patient selection: French women, age >= 70 years
Parameters:
(1) calf circumference in cm
(2) waist circumference in cm
(3) hip circumference in cm
(4) grip strength in kPa
(5) body mass index (BMI) in kg per square meter
