This study examined the validity of the Bod Pod®, using underwater weighing (UWW) as the criterion, for the determination of body density (Db) and estimation of percent body fat (%BF). Thirty-six healthy Black women (25.2 ± 5.3) completed one UWW measurement period and one Bod Pod® measurement period to determine Db. Percent body fat was estimated from Db using the general Siri formula and the race/ethnicity-specific Ortiz formula. Results showed no significant differences between Db (g/cm3) as measured by the Bod Pod® and UWW in adult Black women (p = 0.715). A significant difference (p < 0.001) was found between the Siri and Ortiz %BF estimations, with Ortiz estimating %BF to be approximately 1.0% greater than Siri. These results suggest that while the Bod Pod® is valid in determining Db in adult Black women, the use of race/ethnicity-specific equations are necessary when determining %BF in this population.
