New equations for estimating body cell mass from bioimpedance parallel models in healthy older Germans.
The objectives of this study were to assess for elderly Germans the validity of existing equations for predicting body cell mass (BCM) and to develop from single- and multifrequency bioimpedance (SFBIA, MFBIA) models new prediction equations. In a data-splitting approach, validation and cross-validation were performed in 160 healthy elderly (60- to 90-yr) subjects. BCM was determined using a te...
متن کاملImproved assessment of body cell mass by segmental bioimpedance analysis in malnourished subjects and acromegaly.
BACKGROUND Estimation of body cell mass (BCM) has been regarded valuable for the assessment of malnutrition. AIM To investigate the value of segmental bioelectrical impedance analysis (BIA) for BCM estimation in malnourished subjects and acromegaly. METHODS Nineteen controls and 63 patients with either reduced (liver cirrhosis without and with ascites, Cushing's disease) or increased BCM (a...
متن کاملA comparison of bioimpedance methods for detection of body cell mass change in HIV infection.
The maintenance of body cell mass (BCM) is critical for survival in human immunodeficiency virus (HIV) infection. Accuracy of bioimpedance for measuring change (Delta) in intracellular water (ICW), which defines BCM, is uncertain. To evaluate bioimpedance-estimated DeltaBCM, the ICW of 21 weight-losing HIV patients was measured before and after anabolic steroid therapy by dilution (total body w...
متن کاملPredicting body cell mass with bioimpedance by using theoretical methods: a technological review.
The body cell mass (BCM), defined as intracellular water (ICW), was estimated in 73 healthy men and women by total body potassium (TBK) and by bioimpedance spectroscopy (BIS). In 14 other subjects, extracellular water (ECW) and total body water (TBW) were measured by bromide dilution and deuterium oxide dilution, respectively. For all subjects, impedance spectral data were fit to the Cole model...
متن کاملDiagnostic Accuracy of Body Mass Index and Fasting Glucose for The Prediction of Gestational Diabetes Mellitus after Assisted Reproductive Technology
Objective Background: To determine maternal pre-pregnancy body mass index (BMI), first trimester fasting blood sugar (FBS) and the combination (BMI+FBS) cut-points for at risk pregnant women conceived by assisted reproduction technology (ART) to better prediction of infertile women’s risk of developing gestational diabetes mellitus (GDM). MaterialsAndMethods In this nested case-control study, 2...
