Multiple regression equations to predict body fat mass (FM) of 117 healthy adults.

Females: FM = 18.545 − 0.312 HT + 0.653 WT + 4.522 LOWERABD_HT

Males: FM = 56.602 + 0.799 PCTTOTAL − 0.063 SURFUP + 25.366 LOWERABD_HT

HT = height in cm; WT = weight in kg; LOWERABD = the surface (cm²) of the lateral surface between the lines drawn by the APP at the belly and the hip (Figure 1C); SURFUP = the surface (cm²) of the lateral section between the line at the belly drawn by the APP and the operator-drawn line at the eyes; PCTTOTAL = the percent of occupation of the entire lateral surface from ankle to eyes (Figure 1B).
