STUDY OBJECTIVE Weight loss is a common complication of COPD, associated with negative outcomes. Weight restoration has been associated with improved outcomes. The effects of oxandrolone, an adjunct to help restore weight, were evaluated in patients with COPD. DESIGN Prospective, open-label, 4-month clinical trial. SETTING Twenty-five community-based pulmonary practices throughout the Unite...

Bioelectrical impedance analysis (BIA) is a widely used method for estimating body composition, yet issues concerning its validity persist in the literature. The purpose of this study was to validate percentage of body fat (BF) values estimated from BIA and skinfold (SF) with those obtained from hydrodensitometry (HD). Percent BF values measured via hand-to-hand BIA (BIAH), foot-to-foot BIA (BI...

OBJECTIVES To explore the usefulness of Bioelectrical Impedance Analysis (BIA) for general use by identifying best-evidenced formulae to calculate lean and fat mass, comparing these to historical gold standard data and comparing these results with machine-generated output. In addition, we explored how to best to adjust lean and fat estimates for height and how these overlapped with body mass in...

INTRODUCTION The height-weight difference index (HWDI) is a new indicator for evaluating obesity status. While body-fat percentage (BF%) is considered to be the most accurate obesity evaluation tool, it is a more expensive method and more difficult to measure than the others. OBJECTIVE Our objectives were to find the relationship between HWDI and BF% and to find a BF% prediction model from HW...

AIM The purpose of this study was to compare whole-body (50 kHz alternating current) and segmental (5 kHz alternating current) bioelectrical impedance analysis (BIA) in the assessment of manifested edema of the upper limbs. PATIENTS AND METHODS Whole-body and segmental BIA were performed in 30 patients with edema of the upper limb following breast cancer treatment. RESULTS Pearson correlati...

Bioimpedance analysis (BIA) is a potential field and clinical method for evaluating fat percentage and body mass. Multi-frequency bioimpedance monitoring methodology used for the analysis purpose is a widely used method to estimate body composition. The multifrequency bioimpedance analysis using network analyzer is a relatively quick, simple and non-invasive technique to measure body compositio...
