Comparison of body adiposity index (BAI) and air displacement plethysmograph with estimations of % body fat in adults with Down’s syndrome

Background/Objectives: The aim of this study was to verify the agreement between body fat percentage (%BF) values evaluated by air displacement plethysmograph (ADP) and body adiposity index (BAI) in adults with Down’s syndrome (DS). Subjects/Methods: Forty-five adults with DS volunteered to participate in this study (19 women; age 28.7±8.5 years and 26 men; age 29.1±8.8 years). The %BF was measured by ADP (%BF ADP ) and estimated by anthropometric measures [%BF=(hip circumference/height) 1.5 −18] (%BF BAI ). Agreement between methods was evaluated by paired t -test, Pearson’s correlation coefficient and Bland–Altman analysis. Results: Although high correlation coefficients were found between %BF ADP and %BF BAI for women ( r =0.78, P
