Concurrent Validity of the BOD POD and Dual Energy X-Ray Absorptiometry Techniques for Assessing Body Composition in Young Women

Abstract

The purpose of this study was to determine the concurrent validity of the BOD POD (BP) (Life Measurement Instruments) and Dual Energy X-Ray Absorptiometry (DXA) Elite 4500A (Hologic, Inc.) techniques for assessing the body fat percentage of young women. The participants were forty-three white college-aged women (19.4±1.4 years) with a BMI of 23.4±2.3. Both body composition analyses were completed on the same day and were taken within 10 minutes of each other. Body fat percentage was estimated to be 24.3 (SE=1.1) and 23.8 (SE=0.8) using the BP and DXA techniques, respectively. Exact matches, in terms of body fat percentage, were obtained for 10 of the 43 participants (23.3%). In conclusion, our data supports the concurrent validity of the BP and DXA techniques for assessing body fat in young women. J Am Diet Assoc. 2002;102:1677-1679.
