Revista da Associação Médica Brasileira

Abstract

To analyze the validity of methods for assessing body fat in children and adolescents from a systematic review. A search was conducted by two independent researchers, the electronic databases MEDLINE, BioMed Central, SciELO and LILACS. For inclusion, the articles should be written in English or Portuguese language and to be used multicompartment models as the criterion measure model, with a body fat measurement of whole body in children and adolescents, non-athletes. A preliminary search resulted in 832 papers and after selection steps 12 composed this review. Selected papers were published between 1997 and 2010, with sample based in children and adolescents with levels of relative body fat from 20.7 to 41.4%. The methods used were: dual energy X-ray absorptiometry (58.3%), isotope dilution (41.6%), skinfold thickness (33.3%), hydrostatic weighing (25%), impedance bioelectrical (25%), air displacement plethysmography (16.6%), and total body electrical conductivity (8.3%). From the a...
