What assessment technique can evaluate both bone density and body fat percentage?

The correct assessment technique that evaluates both bone density and body fat percentage is DEXA, which stands for Dual-Energy X-ray Absorptiometry. DEXA scans utilize low-dose X-rays at two different energy levels to differentiate between bone mass and soft tissue, which includes fat and lean mass.

This technology is particularly valued for its accuracy in measuring bone density, making it a standard clinical tool for diagnosing osteoporosis and assessing fracture risk. Additionally, DEXA can provide a comprehensive body composition analysis, including the percentage of fat and lean mass, thus offering a multi-faceted view of an individual’s body composition health.

In contrast, while hydrostatic weighing and the Bod Pod primarily measure body fat percentage through changes in buoyancy and air displacement, respectively, they do not provide direct assessments of bone density. Bioelectrical impedance analysis uses electrical signals to estimate body composition but is less accurate for bone density assessments and can be influenced by hydration levels, leading to variability in results.
