About U.S. Navy Circumference Methodology:
Developed by Hodgdon and Beckett at the Naval Health Research Center, this method correlates cross-sectional body circumferences to multi-compartment hydrodensitometry scans with typical error margins of ±3% to 4%. It provides a useful non-invasive baseline for tracking changes in body composition over time.
