Use of bioelectrical impedance analysis to assess body composition in rural Gambian children

摘要: To validate the Tanita BC-418MA Segmental Body Composition Analyser and four-site skinfold measurements for prediction of total body water (TBW), percentage fat-free mass (%FFM) fat (%BF) in a population rural Gambian children. One hundred thirty-three healthy children (65 males 68 females). FFM estimated by inbuilt equations supplied with system was assessed comparison deuterium oxide dilution novel were produced. Deuterium also used to develop %BF based on skinfolds (biceps, triceps, subscapular suprailiac). The underestimated compared all sex age categories (P<0.003), greater accuracy younger males. best %FFM obtained from variables height, weight, sex, impedance, four thickness (adjusted R2=0.84, root mean square error (MSE)=2.07%). These data suggest that instrument may be reliable field assessment technique African children, when using gender-specific convert impedance into estimates FFM.
