Study determines the accuracy of the Galaxy Watch4 body composition measurements

You’ve probably heard of the Body Mass Index and that it is not a particularly good measurement of your physical form. Bioelectric Impedance Analysis (BIA) is much better, but until relatively recently equipment for it was only available in gyms and clinics. Today smart wearables like the Galaxy Watch4 and Galaxy Watch5 can measure BIA anytime, anywhere. But how accurate can those wrist-worn devices be? A joint research team from Louisiana State University, Pennington Biomedical Research Center and the University of Hawaii Cancer Center performed a study to find out.
