dc.description.abstractObesity has increased exponentially within the last three decades and is now widely recognized as one of today's leading health threats due to it being a risk factor for diseases such as type 2 diabetes, cardiovascular disease, and hypertension. In recent years, there have been advances in technology such as bioelectrical impedance analysis (BIA), dual-energy X-ray absorptiometry (DEXA), and air displacement plethysmography that has been used to categorize individuals into percent fat categories. However, there are still concerns with the validity of these devices. PURPOSE: The purpose of this study was to analyze the validity of the InBody 520, BodPod, and Hologic DEXA against hydrostatic weighing. METHODS: 32 male and 30 female subjects performed body composition testing using the InBody 520, BodPod, Hologic DEXA, and hydrostatic weighing. RESULTS: The constant error values and mean values for percent body fat were the highest amongst the DEXA compared to the InBody and BodPod. The InBody showed a non-significant relationship (p=0.11, p= 0.47, and p=0.26) between constant error values and percent body fat values for hydrostatic weighing for females, males, and all subjects respectively. The BodPod showed a significant negative relationship (p=0.04 and p<0.01) between constant error values and percent body fat from hydrostatic weighing but a non-significant negative relationship (p=0.16) for males. The DEXA showed a significant positive relationship (p <0.01 and p=0.05) between constant error and percent body fat for hydrostatic weighing for males and all subjects respectively. CONCLUSION: The BodPod underestimated individuals with less fat mass and overestimated individuals with more fat mass. The Hologic DEXA consistently overestimated percent fat in all individuals.en_US
