Clinical Methodology: US Navy Circumference Method
This workstation utilizes the Hodgdon-Beckett regression analysis developed at the Naval Health Research Center. This formula estimates body density by measuring standardized circumference storage sites.
Professional FAQ
1. How accurate is the US Navy Method?
Studies show the Navy formula is accurate within ±3.5% of DEXA scans, making it the most reliable clinical surrogate for non-invasive tracking.
2. Does high muscle mass affect the results?
Since the formula uses neck size as a proxy for lean mass, individuals with highly muscular necks may see slight overestimations of lean mass, though the trend remains accurate for progress tracking.
3. Why is the 'Essential Fat' threshold important?
Essential fat (2-5% men, 10-13% women) is critical for hormonal and immune health. Dropping below these levels is clinically dangerous.
