摘要: The purpose of this study was to identify the BIA (bioimpedance analysis) equation that yields best estimate body composition for 122 premenopausal African-American women (18-40 yr). Total density (Db) determined by hydrodensitometry at residual lung volume and converted %BFHD using Siri (31) formula, used calculate reference fat-free mass (FFM). Resistance reactance were measured a Valhalla bioimpedance analyzer. predictive accuracy generalized, age-gender, race-specific, fatness-specific, manufacturer's equations compared. There significant correlations between FFMHD FFMBIA all (r = 0.85 0.92). Except modified Segal fatness-specific equations, prediction errors (SEE E) exceeded 2.8 kg. For individuals, %BF derived from predicted within +/- 3.5% BF 69% subjects. This percentage less (34-53%) other equations. These results suggest estimating is improved when are used. We recommend assess FFM women.
