Comparison of body composition measures to dual-energy X-ray absorptiometry

The purpose of the study was to examine the validity of body mass index (BMI), bioelectrical impedance (BIA) and skin folds (SF) in predicting body composition when compared to dual-energy X-ray absorptiometry (DEXA). Researchers examined four accepted methods of body composition assessment: BMI, DE...

Description
Summary:The purpose of the study was to examine the validity of body mass index (BMI), bioelectrical impedance (BIA) and skin folds (SF) in predicting body composition when compared to dual-energy X-ray absorptiometry (DEXA). Researchers examined four accepted methods of body composition assessment: BMI, DEXA, SF and BIA. A convenience sample of sedentary college-aged students (N=108) from introductory health classes at a southern university were chosen to participate in a 12-week behavior change study. All measures were obtained by trained technicians with proficiency in each of the body composition measures. Pearson correlations for each comparison were 0.824 for DEXA and SF, 0.798 for DEXA and BIA, and 0.551 for DEXA and BMI. All correlations were significant to p
