摘要：
The purpose of this investigation was to evaluate measurements of body-fat percentage (BF%) in 4 body-mass-index- (BMI)-based equations and dual-energy X-ray absorptiometry (DXA) in individuals with Down syndrome (DS). Ten male and 10 female adults with DS volunteered for this study. Four regression equations for estimating BF% based on BMI previously developed by Deurenberg et al. (DEBMI-BF %), Gallagher et al. (GA(BMI-BF%)), Womersley & Durnin (WOBMI-BF%), and Jackson et al. (JA(BMI-BF%)) were compared with DXA. There was no significant difference (p=.659) in mean BF% values between JA(BMI-BF%) (BF%= 40.80%+/- 6.3%) and DXA (39.90%+/- 11.1%), while DEBMI-BF% (34.40%+/- 9.0%), WOBMI-BF%, (35.10%+/- 9.4%), and GA(BMI-BF%) (35.10%+/- 9.4%) were significantly (p<.001) lower. The limits of agreement (1.96 SD of the constant error) varied from 9.80% to 16.20%. Therefore, BMI-based BF% equations should not be used in individuals with DS.
