This paper describes a model for predicting hemoglobin (Hb) by using bioelectrical impedance analysis (BIA) in dengue patients in the Hospital Universiti Kebangsaan Malaysia (HUKM). Bioelectrical impedance measurements were conducted on 83 (47 males and 36 females) serologically confirmed dengue fever (DF) and dengue hemorrhagic fever (DHF) patients during their hospitalization. The predictive ...

OBJECTIVE To investigate the accuracy of bioelectric impedance analysis and anthropometry to assess percentage body fat (BF %) against underwater weighing (UW). DESIGN AND METHODS A cross sectional study, 102 girls, aged 11-15, were recruited from two Junior High Schools in Jakarta. MEASUREMENTS Measurements of percent-age body fat (BF%) using underwater weighing (UW), bioelectrical impedan...

background: chronic obstructive pulmonary disease (copd) is considered a major public health problem in the world. weight loss, muscle and fat mass depletion are common nutritional problems in copd patients and are determinant factors in pul­monary function, health status, disability and mortality. in the present study, we assessed nutritional status in copd pa­tients. methods: this cross-secti...

Bioelectric-impedance analysis overestimates fat-free mass in obese people. No clear hypotheses have been presented or tested that explain this effect. This study tested the hypothesis that adipose tissue affects measurements of resistance by using data for whole body and body segment resistance and by using muscle, adipose tissue, and bone volumes from magnetic resonance imaging for 86 overwei...

BACKGROUND Adequacy of body fluid volume improves short- and long-term outcomes inpatients with heart and kidney disorders. Bioelectrical impedance vector analysis (BIVA) has the potential to be used as a routine method at the bedside for assessment and management of body fluids. METHODS Impedance (Z vector) is a combination of resistance, R (function of intra- and extracellular fluid volume)...

The aims of this study were to develop and validate a prediction equation of fat-free mass (FFM) based on bioelectrical impedance analysis (BIA) and anthropometry using air-displacement plethysmography (ADP) as a reference in Asian neonates and to test the applicability of the prediction equations in an independent Western cohort. A total of 173 neonates at birth and 140 at two weeks of age wer...

BACKGROUND Bioelectrical Impedance Analysis (BIA) is a fast, practical, non-invasive, and frequently used method for fat-free mass (FFM) estimation. The aims of this study were to validate predictive equations of BIA to FFM estimation in Army cadets and to develop and validate a specific BIA equation for this population. METHODS A total of 396 males, Brazilian Army cadets, aged 17-24 years we...

Methods: 57 men with stable HF, NYHA class I to III, and ejection fraction (EF) ≤45 were studied. Leg fluid volume (LFV) was measured by bioelectric impedance; right calf and neck circumference were measured (with lines drawn to ensure consistency) before and after sleep. Patients with predominant OSA (≥ 50% obstructive events) and apnea-hypopnea index (AHI) ≥15 were offered continuous positive...
