IMPACT OF FAT-FREE ADIPOSE TISSUE ON THE PREVALENCE OF LOW MUSCLE MASS ESTIMATED USING CALF CIRCUMFERENCE IN MIDDLE-AGED AND OLDER ADULTS

Previous studies proposed calf circumference cutoff values for predicting dual-energy X-ray absorptiometry (DXA)-derived low muscle mass. However, DXA-derived appendicular lean mass (aLM) includes non-skeletal muscle components such as the appendicular fat-free component of adipose tissue fat cells (aFFAT). The purpose of this study was to compare the calf circumference method of classification before (Model #1) and after (Model #2) eliminating...
