Purpose: Our aim was to investigate the link between adiposity fat indexes obtained using ultrasound (US) examination, total and android fat amount by dual-energy x-ray absorptiometry (DXA), and body weight (BW) in normal-weight, over-weight and obese subjects. Material & Methods: We retrospectively analyzed body composition (BC) parameters of 138 normal-weight (62M, 76F, age 41.2613.6year-old, BMI 22.361.5Kg/m2), 92 over-weight (60M, 32F, age 48.2613.3year-old, BMI 27.061.4Kg/m2) and 42 obese (4M, 38F, age 49.9612.8year-old, BMI 37.066.0Kg/m2) subjects. Data were collected from different studies in our Hospital where US and DXA evaluations were simultaneously performed for BC assessment. The carotid intimal-medial-thickness (CIMT), the ratio between minimum subcutaneous fat-thickness and maximum pre-peritoneal fat-thickness (wall-fat-index – WFI), and that one between maximum subcutaneous fat-thickness and intra-abdominal fat-thickness (MAR) were considered for US evaluations. Simple regression and ANOVA were used for the analysis (only p,0.05 were considered). Results: In all groups, WFI had significant correlations with total fat mass (FM) and FM percentage, while MAR got a relation with only BW; moreover, CIMT was related to android and whole-body FM. FM percentage in android region was linked to MAR and WFI only in normal-weight and over-weight subjects. Android FM was correlated with MAR only in normal-weight subjects. Conclusion: DXA, US and BW look at the human body from different points of view. An integration of these three techniques should be considered when the assessment of BC is needed.

Data were collected from different studies in our Hospital where US and DXA evaluations were simultaneously performed for BC assessment. The carotid intimal-medial-thickness (CIMT), the ratio between minimum subcutaneous fat-thickness and maximum pre-peritoneal fat-thickness (wall-fat-index – WFI), and that one between maximum subcutaneous fat-thickness and intra-abdominal fat-thickness (MAR) were considered for US evaluations.
