MORALES GONZALEZ, Maraelys et al. Influence of the electric resistance in the estimate of the total body water and the fat free mass . MEDISAN [online]. 2013, vol.17, n.10, pp. 7002-7011. ISSN 1029-3019.

A cross-sectional and controlled study was carried out, in order to evaluate the influence of the unadjusted and adjusted values of electric resistance, measured with the analyzers Bodystat^® 1500-MDD and BioScan^® 98 in the total body water and the fat free mass, of 31 apparently healthy persons and 31 children with different disorders, assisted in the Oncohematology Service of the Southern Pediatric Hospital in Santiago de Cuba, from September to October, 2009. Two equations were used for each biological parameter, and as statistical criterium the paired samples T test was used. The difference between the unadjusted and adjusted values of the electric resistance didn't influence significantly in the 2 biological parameters; therefore, it is possible to use them indistinctly to estimate the total body water and the fat free mass in apparently healthy individuals and patients with different diseases.

Palabras clave : electric resistance; total body mass; fat free mass; analyzers of electric bioimpedance; Oncohematology Service; secondary health care.
