HIGH CORRELATION WITH DXA FOR LEAN MASS MEASUREMENTS

A 2011 study published by Clinical Nutrition compared the accuracy of DSM-BIA (InBody 720) against DXA with 484 middle-aged participants. The study found that the InBody had a 99% correlation to DXA when measuring lean mass in normal and overweight populations. “In conclusion, this study shows DSM-BIA to be a valid tool for the assessment of whole body composition and segmental lean mass measurements in middle-aged population when validated against DEXA

HIGH ACCURACY AND EASE OF USE AS A FIELD-BASED ASSESSMENT TOOL

A study published in 2010 found results from the InBody 520 to be highly correlated with fat-free mass (FFM) measures from hydrostatic weighing (96%).  The study also concluded that the InBody does not require a high degree of technical skill, making it easy to use and safe, and also provides simultaneous measures of body mass, body composition, and TBW in a short period of time. “These advantages may make MFBIA attractive to educational institutions that may not have access to trained anthropometrists, HW, ADP, and DXA and to address concerns that have been expressed by coaches, officials, and athletic trainers who question the results of SK testing performed by someone who may not be completely objective or impartial.”

HIGH ACCURACY AND EASE OF USE AS A FIELD-BASED ASSESSMENT TOOL

“The single-cuff oscillometric device InBody BPBIO320 developed for self-measurement by adults in public spaces passed all the validation requirements of the 2010 ESH-IP and can be recommended for clinical use.” The test–reference BP difference was 0.5±4.3/−1.1±4.3mmHg (systolic/diastolic) in participants with arm circumference less than 31.4 cm (n=17) and −1.3±6.0/0.2±4.8mmHg in those with an arm circumference of at least 31.4 cm (n=16). This indicates that the margin of error is ~5/5.5 mmHg (systolic/diastolic) in those with smaller arms, and ~7/5 mmHg (systolic/diastolic) in those with higher arm circumference.
