Artificial Neural networks (ANN) are finding many uses in the medical diagnosis applications. Different diseases such as acquired immuno deficiency syndrome (AIDS), malnutrition, cardiovascular diseases, osteoporosis are related to body composition topologies such as fat mass (FM), fat free mass (FFM), total body water (TBW), bone mineral contents (BMC) and bone mineral density (BMD). Due to he...

Body mass index (BMI) is the most commonly used measure of obesity. Recently, some investigators have advocated direct measurement of adiposity rather than use of the BMI. This study was undertaken to determine the ability of BMI to predict body fat levels in three populations of West African heritage living in different environments. A total of 1,054 black men and women were examined in Nigeri...

AIM The purpose of this prospective study was to evaluate resistance (R) and phase angle (Pa) determined by single-frequency whole-body bioelectrical impedance analysis (BIA), as predictors for the early onset of edema of the upper limb in patients undergoing surgical treatment for breast cancer. MATERIALS AND METHODS Whole-body BIA was performed before surgery, as well as at two days, at one...

BACKGROUND The aim of this study was to determine reference values for sarcopenia indices using different methods in healthy Saudi young men. METHODS Participants included 232 Saudi men aged between 20 and 35 years. The study measured anthropometric indices, blood pressure, hand grip strength, and lean muscle mass using dual-energy X-ray absorptiometry (DXA), and bioelectrical impedance analy...

Bioelectrical impedance analysis (BIA) is a noninvasive and relatively inexpensive method of assessing body composition. Manufacturers of BIA technology recommend to avoid testing women when they perceive to be retaining water during the menstrual cycle. The purpose of the present investigation was to examine the effect of the menstrual cycle on body composition determined by contact-electrode ...

BACKGROUND Few large studies in China have investigated total physical activity and sedentary leisure time and their associations with adiposity. OBJECTIVE We investigated determinants of physical activity and sedentary leisure time and their associations with adiposity in China. DESIGN A total of 466,605 generally healthy participants (age: 30-79 y, 60% female) in the China Kadoorie Bioban...

BACKGROUND AND AIMS Bioelectrical impedance analysis (BIA) is a widely used technique to assess body composition and nutritional status. While bioelectrical values are affected by diverse variables, there has been little research on validation of BIA in acute illness, especially to understand prognostic significance. Here we report the use of BIA in acute febrile states induced by influenza. ...

This paper investigates the low-frequency response of a multi-stage bioelectric amplifier intended for use in the measurement of the electrocardiogram (ECG) using dry contact electrodes. These electrodes have an impedance which is typically an order of magnitude greater than that of the standard disposable self-adhesive electrodes used in clinical ECG recording. The design was undertaken with t...

Low muscle mass is associated with risk of CKD progression, cardiovascular disease events, and mortality in avarietyof settings (1). It iswidelyhypothesized that these associations may be confounded by conditions associated with low muscle mass, including frailty, poor physical fitness, poor nutritional status, and greater comorbidity. However, lowmuscle is also hypothesized to worsen insulin r...
