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...
Measurement of body water by multifrequency bioelectrical impedance spectroscopy in a multiethnic pediatric population
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...
Comparison of air-displacement plethysmography with hydrostatic weighing and bioelectrical impedance analysis for the assessment of body composition in healthy adults
Adiposity body fat body density humans
2016/5/31
Over the past decade, considerable attention has
been paid to accurately measuring body composition in diverse
populations. Recently, the use of air-displacement plethysmography
(AP) was proposed a...
Use of the leg-to-leg bioelectrical impedance method in assessing body-composition change in obese women
obesity fat-free mass percentage body fat
2016/5/30
There is little information on whether bioelectrical
impedance analysis (BIA) accurately predicts changes in body
composition associated with energy restriction, exercise, or both.
Bioelectrical impedance plethysmographic analysis of body composition in critically injured and healthy subjects
Bioelectrical impedance body composition critical illness
2016/5/30
Determination of body composition during critical
illness is complex because of various patient-related and
technical factors. Bioelectrical impedance is a promising
technique for the analysis of b...
Body fat measurement by bioelectrical impedance and air displacement plethysmography: a cross-validation study to design bioelectrical impedance equations in Mexican adults
bioelectrical impedance fat measurement
2008/4/23
The study of body composition in specific populations by techniques such as bio-impedance analysis (BIA) requires validation based on standard reference methods. The aim of this study was to develop a...
Validation of bioelectrical impedance analysis in patients with amyotrophic lateral sclerosis
Amyotrophic lateral sclerosis fat-free mass
2016/12/30
Amyotrophic lateral sclerosis (ALS) is a neurologic disease with an unfavorable prognosis that may be accompanied by malnutrition or overweight. Nutritional status is difficult to evaluate in these pa...
Development of bioelectrical impedance analysis prediction equations for body composition with the use of a multicomponent model for use in epidemiologic surveys
total body water fat-free mass multicomponent model
2016/12/29
Previous studies to develop and validate bioelectrical impedance analysis (BIA) equations to predict body composition were limited by small sample sizes, sex specificity, and reliance on reference met...
Bioelectrical impedance measurements in patients with gastrointestinal disease: validation of the spectrum approach and a comparison of different methods for screening for nutritional depletion
Patients gastrointestinal disease depletion
2017/1/4
BIS measures of body fluids are influenced by the presence of depletion, probably because of alterations in the electric properties of the body at the cellular level. However, for screening purposes, ...
Bioelectrical impedance analysis models for prediction of total body water and fat-free mass in healthy and HIV-infected children and adolescents
Bioelectrical impedance analysis pediatrics ethnicity puberty HIV infection
2016/12/19
Background: Bioelectrical impedance analysis (BIA) is an attractive method of measuring pediatric body composition in the field, but the applicability of existing equations to diverse populations...
Multifrequency bioelectrical impedance analysis in women with a normal and hypertensive pregnancy
Pregnancy multifrequency bioelectrical impedance analysis gestational hypertension
2016/6/8
Background: An increase in total body water is common in normal

maternal adaptation to pregnancy.
Objective: The aim of the present study wa...
Phase angle from bioelectrical impedance analysis remains an independent predictive marker in HIV-infected patients in the era of highly active antiretroviral treatment
Acquired immunodeficiency syndrome AIDS, biological markers body fluid compartments body composition
2016/6/7
Background: Highly active antiretroviral treatment (HAART)
