Background: Sarcopenia is a condition characterized by the loss of muscle mass and strength with aging. Little research has been done in the local setting to establish the muscle mass standards that can be used for sarcopenia diagnosis.

Objectives: To compare the body composition measured by bioelectric impedance analysis (BIA) versus dual energy X-ray absorptiometry (DEXA) and to define the cut-off points by gender based on the skeletal muscle index of a normal Filipino population using BIA method. This research is part of a larger study on the prevalence of sarcopenia in the Philippines.

Methods: 12 men and 13 women ages 18 to 25 years old were measured for body composition using BIA and DEXA. In addition, 140 normal Filipino young adults ages 18 to 25 years old were measured for skeletal muscle mass using BIA, and the skeletal muscle index (SMI) was calculated.

Results: Most BIA measurements did not differ significantly from DEXA measurements. The normal reference values for males and females, respectively, were 9.07 kg/m2 and 6.76 kg/m2. Class 1 sarcopenia cut-off values were 8.45 - 7.82 kg/m2 for men and 6.30- 5.84 kg/m2 for women. Class 2 sarcopenia cut-off values were <7.82 kg/m2 for men and <5.84 kg/m2 for women. The female and male values are near the range of cut-offs from other Asia-Pacific countries.

Conclusion: Skeletal muscle mass was measured from a normal Filipino population using bioelectric impedance analysis and the reference standards for the diagnosis of sarcopenia were established.
