Bioelectrical impedance: effect of 3 identical meals on diurnal impedance variation and calculation of body composition
diurnal variation body composition meal ingestion
2016/6/14
Bioelectrical impedance analysis (BIA) can be
used for estimating body composition. Earlier studies showed
that the ingestion of meals lowers bioelectrical impedance, but
none studied the effect of...
Bioelectrical impedance analysis in HIV-infected patients treated with triple antiretroviral treatment
AIDS anti-HIV agents body weight
2016/6/1
Triple antiretroviral treatment including protease
inhibitors (PIs) delays the clinical progression of HIV infection
and may thus reduce the risk of malnutrition. However, fat redistribution
(lipod...

Total body water extracellular water intracellular water
2016/6/1
Bioelectrical impedance spectroscopy (BIS) may
provide a noninvasive, rapid method for the assessment of total
body water (TBW), extracellular water (ECW), and intracellular
water (ICW). Few studie...
