Evaluation of body composition: why and how?1,2
نویسنده
چکیده
Evaluation of human body composition in vivo remains a critical component in the assessment of nutritional status of an individual. Whereas traditional measurements of standing height and body weight provide information on body mass index and, hence, the risk of some chronic diseases, advanced technologies, such as dual X-ray absorptiometry, air displacement plethysmography and various forms of bioelectrical impedance analysis enable the determination of soft tissue composition (fat and lean) as well as bone. This review summarises the physical bases of these methods and critically evaluates their accuracy in observational and interventional studies. It also discusses a new approach, bioelectrical impedance vector analysis, which assesses the hydration status of an individual, and includes pertinent examples of its novel applications in clinical nutrition.

Evaluation of growth performance and body composition of great sturgeon (Huso huso) juveniles fed with different levels of Ethylenediaminetetraacetic acid
In this study, the effect of Ethylenediaminetetraacetic acid (EDTA) was evaluated on growth performance and body composition in beluga (Huso huso) juveniles. For this purpose, a total of 225 beluga juveniles with initial weight 38.47 ± 0.58 gr (Mean ± Standard Division) were fed with five treatments with three replications including 0 g/kg EDTA (Control, C), 5 g/kg EDTA (EDTA 5), 10 g/kg ED...
