Bioelectrical impedance analysis (BIA) is a method for estimating body composition, in particular body fat and muscle mass, where a weak electric current flows through the body, and the voltage is measured in order to calculate impedance (resistance and reactance) of the body.
The bioelectrical impedance analysis (BIA) method is a lower-cost (from less than one to several hundred US dollars in 2006 [16]) but less accurate way to estimate body fat percentage. The general principle behind BIA: two or more conductors are attached to a person's body and a small electric current is sent through the body.
If you want a more specific analysis, Khader recommends having a dietitian perform a bioelectrical impedance analysis (BIA), a highly accurate test for body fat and muscle mass done through ...
The Beck Anxiety Inventory (BAI) is a formative assessment and rating scale of anxiety. This self-report inventory, or 21-item questionnaire uses a scale (social sciences); the BAI is an ordinal scale; more specifically, a Likert scale that measures the scale quality of magnitude of anxiety. [1]
A wide variety of body composition measurement methods exist. The gold standard measurement technique for the 4-compartment model consists of a weight measurement, body density measurement using hydrostatic weighing or air displacement plethysmography, total body water calculation using isotope dilution analysis, and mineral content measurement by dual-energy X-ray absorptiometry (DEXA). [1]
Stated advantages of the BAI are that it approximates body fat percentage, while the widely used BMI is known to be of limited accuracy, and is different for males and females with similar percentage body adiposity; and that it does not involve weighing, so can be used in remote locations with limited access to scales.
