BACKGROUND Malnutrition is closely related to inflammation and atherosclerosis in uraemic patients. There is still debate on how to quantify nutritional status in order to achieve the best prediction of mortality and hospitalization. METHODS Different methods to detect malnutrition were prospectively investigated for their prognostic impact on mortality and hospitalization of haemodialysis (H...

The intention of the study was to determine nutritional state and body cell mass in patients with COPD in comparison with healthy volunteers between 50 and 75 years of age. Therefore, body cell mass (BCM), phase angle and the relation between extra cellular mass and body cell mass ECM/BCM was measured with the help of bioelectrical impedance analysis (BIA). While 10.4 % of COPD patients (male 5...

BACKGROUND In clinical practice, patient friendly methods to assess body composition in obese adolescents are needed. Therefore, the bioelectrical impedance analysis (BIA) related fat-free mass (FFM) prediction equations (FFM-BIA) were evaluated in obese adolescents (age 11-18 years) compared to FFM measured by dual-energy x-ray absorptiometry (FFM-DXA) and a new population specific FFM-BIA equ...

Two hundred and fifty seven male Caucasian ultra-endurance athletes were recruited, pre-race, before different swimming, cycling, running and triathlon races. Fat mass and skeletal muscle mass were estimated using bioelectrical impedance analysis (BIA) and anthropometric methods in order to investigate whether the use of BIA or anthropometry would be useful under field conditions. Total body fa...

BACKGROUND The aim of the present study was to validate the usefulness of the new octapolar multifrequency bioelectrical impedance analysis (BIA) for assessment of appendicular skeletal muscle mass (ASM) by comparing it with that of dual-energy X-ray absorptiometry (DXA) and to investigate the prevalence of sarcopenia in Chinese community-dwelling elderly according to Asian Working Group for Sa...

Bioelectrical impedance analysis (BIA) analysis was carried out in the field on anaesthetized Salvelinus fontinalis electrofished from a mountain stream in Alberta, Canada; the fish were then sacrificed for subsequent analysis of tissue composition. Water content was assessed by comparing wet and dry mass, and total body lipid content was measured by Soxhlet extraction with petroleum ether. A m...

Bioelectrical impedance analysis (BIA) is an inexpensive, quick and non-invasive method to determine body composition. Equations used in BIA are typically derived in healthy individuals of European descent. BIA is specific to health status and ethnicity and may therefore provide inaccurate results in populations of different ethnic origin and health status. The aim of the present study was to t...

Nutritional status should be assessed at regular intervals as part of management of human immunodeficiency virus (HIV) infection. The simplest approach to assessment is serial weight measurement. A comprehensive nutritional assessment includes (1) anthropometric measurements of body composition; (2) biochemical measurements of serum protein, micronutrients, and metabolic parameters; (3) clinica...

INTRODUCTION AND OBJECTIVES The study was conducted to evaluate soft tissue hydration and mass through pattern analysis of vector plots as height, normalized resistance, and reactance measurements by bioelectric impedance vector analysis (BIVA) in patients with breast cancer. MATERIALS AND METHODS Whole-body measurements were made with ImpediMed bioimpedance analysis SFB7 BioImp v1.55 (Pinken...

Obesity/Overweight is a recognized risk factor for most of the disorders and risk stratification is based on Quetelets index, a surrogate measure of fatness. Currently used body mass index (BMI) cut-offs to classify people as overweight/obese does not accurately represent the BMI cut-offs in Nepalese population, due to differences in body structure and composition. This study was conducted to d...
