Obesity has been established as a risk factor for multiple diseases and is an increasing problem throughout the world. Advances in technology have enabled health professionals to use many devices to diagnose individuals as healthy, overweight, or obese. However, there are discrepancies between the validity of the devices. PURPOSE: The purpose of this study is to validate InBody 520 and InBody S10 against the Hologic dual-energy X-ray absorptiometry (DXA) system. METHODS: 50 male and female subjects performed body composition testing on an InBody 520, InBody S10, and a Hologic DXA, followed by repeat measurements on the InBody 520 and S10. RESULTS: Body fat percentage was significantly greater for the DXA when compared to the InBody 520 (p<.001) and significantly greater when compared to the InBody S10 (p=.0006). Lean body mass was significantly less for the DXA when compared to the InBody 520(p=.0362) but not significant when compared to the InBody S10 (p=.0961). Body fat mass was significantly greater for the DXA compared to the InBody 520 (p=.0156) but not significant when compared to the InBody S10 (p=.0909). CONCLUSION: The InBody devices were not significantly different in measuring body fat mass, lean body mass, and percent body fat, but were different when compared to the DXA for the lean body mass and percent body fat.
