CRIS Current Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishPurpose: 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.
