Comparison of Circumference Body Composition Measurements and Eight-Point Bioelectrical Impedance Analysis to Dual Energy X-Ray Absorptiometry to Measure Body Fat Percentage

Abstract

There was good agreement between the three methods assessed in this study. Both waist circumference and gender had an effect on the accuracy of the DSM-BIA and CM measurements.

Comparison of Anthropometric Measures in US Military Personnel in the Classification of Overweight and Obesity

“…However, unlike in our study, the study protocol followed by Combest et al did ensure the hydration status of participants. To the extent that some participants were not well hydrated, this could impact the accuracy of our gold standard BF% estimates by adding random error to the measurement . Second, various studies have reported that older military personnel are at a higher risk of overweight/obesity compared with those in younger age categories .…”

“…A study by Combest et al in active‐duty military personnel reported that BF% by BIA had excellent agreement with DXA in both men ( n = 31; intraclass correlation coefficient = 0.89; 95% CI: 0.78‐0.94) and women ( n = 45; intraclass correlation coefficient = 0.93; 95% CI: 0.87‐0.96). However, unlike in our study, the study protocol followed by Combest et al did ensure the hydration status of participants. To the extent that some participants were not well hydrated, this could impact the accuracy of our gold standard BF% estimates by adding random error to the measurement .…”

“…First, BIA was used as the criterion measure to assess BF% in participants rather than dual‐energy x‐ray absorptiometry (DXA). Although DEA is currently considered the gold standard for assessing body composition , BIA is often favored clinically to assess adiposity because it is less expensive, more portable, and less time consuming than DXA . Some studies have also reported BIA to have good reliability and predictive value compared with DXA , which suggests it may be a more practical criterion measure than DXA for research purposes.…”
