2. Key Insights
from Research
on BIA
01
BIA strongly correlates with DXA for
muscle mass estimation (r = 0.88).
02
Fat-Free Mass and Fat Mass prediction
achieve r = 0.91C0.95.
03
Bone Mass estimation reliability varies (r
= 0.425C0.829).
04
Systematic biases exist but are
correctable.
05
Regional and population-specific
accuracy improves with custom
equations.
3. Applications of BIA in Body Composition Analysis
Estimation of Skeletal Muscle Mass
BIA correlates with DXA for muscle mass, offering a non-invasive
evaluation method. For instance, arm-to-arm impedance aligns with arm
skeletal muscle mass (r = 0.88).
Fat-Free and Fat Mass Assessment
Accurate predictions achieved with equations incorporating
impedance index, correlating well with DXA (r = 0.91C0.95).
Bone Mass Estimation
While BIA estimates bone mineral content effectively, reliability
for segmental bone analysis is moderate (r = 0.425C0.829).
