Accuracy assessment of body composition measurement with KLU

Aim. The paper aims to assess the accuracy of body composition measurement by KLU. Materials and methods. The study involved 32 subjects (males n = 11; females n = 21) aged 19-35 years (25.51 ± 5.82). The following equipment were used for the purpose of the study: height meter, Tanita BC-418 MA body composition analyser, KLU body composition tracker. Results. Significant differences in body fat (more than 20%) were found in 17 subjects. In 6 subjects, this difference was more than 40%. Therefore, in 53.12% of subjects the results obtained with different equipment did not coincide (63.63% - males; 47.61% - females). Better results were reported when measuring body water using the abovementioned equipment. There were no differences of more than 20%, while a 10%-difference was found in 15.62% of subjects. Conclusion. The difference of more than 20% reported in 53.12 % of subjects does not allow to consider KLU as an accurate device for body composition measurement or an accurate individual device. Therefore, its personal use cannot be a reliable method of body composition measurement.
