Bioelectrical Impedance Analysis (BIA)

Bioelectrical Impedance Analysis, or BIA, is considered one of the most exact and accessible methods of screening body fat. In conventional BIA, a person is weighed, and then height, age, gender and weight or other physical characteristics such as body type, physical activity level, ethnicity, etc. are entered in a computer. While the person is lying down, electrodes are attached to various parts of the body and a small electric signal is circulated. In HIV/AIDS, HIV Wasting can be assessed before the patient actually has physical signs of weight loss. All patients receive a baseline assessment and then bi-yearly.
