Background The aim of this study was to verify the accuracy of anthropometric equations to estimate the body density ( BD ) of adults with Down syndrome ( DS ), and propose new regression equations. Materials and methods Twenty‐one males (30.5 ± 9.4 years) and 17 females (27.3 ± 7.7 years) with DS participated in this study. The reference method for BD was air displacement plethysmography ( ADP ). Also, the BD was estimated by anthropometric equations. The body fat percentage ( BF %) was estimated by the Siri equation. Results For females, the Durnin and Womersley equation showed no difference from the ADP , but a trend of underestimation was observed. For males, all equations were significantly different for the BF % from ADP . The equations developed in this study showed a high correlation and acceptable agreement with BF % from ADP in both genders. Conclusion All equations are not valid for DS adults. The new equations developed here were accurate in estimating the BF %.
