Title: Bioimpedancia eléctrica como método para la valoración de la composición corporal

Abstract: The knowledge of the body composition in people is very important for both health and sport. There are several methods to know this information, but the most accurate ones are also the most expensive and less practical, such as dual-energy X-ray absorptiometry (DXA) or magnetic resonance imaging (MRI). The aim of this review was to analyse whether bioelectrical impedance analysis (BIA), in all its variety of devices, with both its pros and cons, is the best method to assess body composition at present. Twenty-eight articles published in the last 5 years have been analysed, showing many inconsistencies in the data obtained, since in many of them the results of BIA) are not similar to the reference methods and therefore can not be considered as valid. These errors can come from many factors, from operator, subject, instrument, environmental, or from the choice of the most appropriate regression equation for the group to be evaluated. Although it is true that it will always be easier to use BIA than the other methods, it cannot be considered the best method since the error range in its analysis is too wide, and in clinical situations this can be serious. In spite of this, more studies are recommended since it continues to be a powerful tool that can be used in various cases at a very affordable cost, easy to use and acquire, and capable of obtaining results immediately.
