Arm fat area (AFA) can be derived from measurements of MUAC and TSFT. AMA is a better indicator of total body fat but not percentage body fat, than TSFT alone. The formula used to calculate AFA (with MUAC and TSFT in mm) is:
AMA can be compared with reference values by age and sex. Theoretically, limb fat area can be calculated for other limbs and the body trunk, but there are no reference values available.
