The accuracy of body-composition measurements in vivo by dual-energy x-ray absorptiometry (DEXA) was assessed in seven pigs (weight: 35-95 kg) by measurement by DEXA in vivo and chemical analysis after postmortem homogenization. The regression lines between these measurements were not significantly different from the line of identity (P > 0.05), the r values were > 0.97, and the corresponding SEEs were 2.9%, 1.9 kg, and 2.7 kg for percent fat, fat tissue mass, and lean body mass, respectively. Changes in fat and lean tissue mass (simulated by placing 8.8 kg porcine lard on the trunk of six women) were accurately measured by DEXA. The measured total-body bone mineral (TBBM) was significantly affected by the lard (P < 0.05). In conclusion, DEXA is an accurate method for measurement of soft-tissue body composition. TBBM measurements in longitudinal studies may, however, be difficult to interpret if considerable change in soft-tissue composition has occurred.
