Recent advances in the application of bioelectrical impedance analysis (BIA) have indicated that a more accurate approach to the estimation of total body water is to consider the impedance of the various body segments rather than simply that of the whole body. The segmental approach necessitates defining and locating the physical demarcation between both the trunk and leg and the trunk and arm....

Radiol Bras. 2014 Mai/Jun;47(3):IX Obesity is currently a public health problem, presenting prevalent exponential growth in all age groups, particularly in children and adolescents. Accumulation of visceral fat is associated with increased cardiovascular risk, metabolic syndrome (hypertension, dyslipidemia, type II diabetes) and insulin resistance. There is a greater correlation than that with ...

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...

This study aimed at comparing BIA and DXA results in assessing body composition in young adults depending on their physical activity level. Eighty healthy 19-30 years old subjects were enrolled and their body composition (Fat Mass and Fat-Free Mass) was assessed by dual-energy X-ray absorptiometry (DXA) and by a newly developed Bioelectrical Impedance Analyzer (BIA - Tanita MC780). A seven-day ...

PURPOSE The aim of this paper is to investigate whether bioelectrical impedance vector analysis (BIVA) can be a suitable technique for the assessment of sarcopenia. We also investigate the potential use of specific BIVA as an indicator of sarcopenic obesity. SUBJECTS AND METHODS The sample comprised 207 free-living elderly individuals of both sexes, aged 65 to 93 years. Anthropometric and bio...

The bioimpedance measurements in humans have been receiving considerable attentions during the past two decades because of several advantages, such as low cost, easy application, non-invasiveness and on-line monitoring. The original bioimpedance technique was bioelectrical impedance analysis (BIA). Within a decade, this technique evolved into the more advanced technique known as bioelectrical i...
