Method Selection Guide
General Population Methods
- Durnin-Womersley (age-specific equations)
- U.S. Navy Method (field-friendly circumference)
- Jackson-Pollock 3-Site (Balance of accuracy and time)
Research-Grade Methods
- Jackson-Pollock 7-Site (Comprehensive assessment)
- DEXA (Laboratory reference method)
- Hydrostatic Weighing (Traditional reference)
Validated Methods Comparison
Comparison of field methods with published accuracy data. Most skinfold ranges are reported as Standard Error of Estimate (SEE); some circumference ranges use reported or estimated field error ranges. Results depend on measurement technique.
| Method | Accuracy Range | Sites | Equipment | Source |
|---|---|---|---|---|
Jackson-Pollock 7-Site | ±3-4% | 7 skinfolds | Calipers | Jackson & Pollock (1978) |
Durnin-Womersley | ±3.5-5% | 4 skinfolds | Calipers | Durnin & Womersley (1974) |
Jackson-Pollock 3-Site | ±4-5% | 3 skinfolds | Calipers | Jackson & Pollock (1978) |
US Navy | ±4-6% | Circumferences | Tape measure | Hodgdon & Beckett (1984) |
