Popis: Cardiometabolic diseases encompass a combination of conditions which lead to an increase in the risk of cardiovascular disease and diabetes. With the increasing percentage of the population becoming overweight, it is important to diagnose when the excess adipose tissue becomes malign. The development of a safe, mobile, non-invasive method that would be easy to perform, and low-cost, but also would offer an accurate assessment of subcutaneous adipose tissue (SAT) both in lean and in obese persons is required. A prototype device using an optical method for measurement of the SAT in vivo has been developed, it contains multiple LEDs with four wavelengths (660nm, 780nm, 870nm, 940nm) distributed at various distances from the photodetector which allow different light penetration depths into the subcutaneous tissue. Five young healthy female students participated in the study; the measurements were performed on three body sites: calf, upper and lower abdomen. The backscattered light acquired with the prototype was compared to SAT measured with high resolution ultrasound imaging. The coefficient of variation indicated high reliability of the measurements. Statistically significant (from r=0.81 to r=0.95; p
