Studies of Nutritional Status and Body Water Using a Novel BIVA Device

We are involved in studies of nutritional and body water assessment in infants, children and mothers in Sub-Saharan Africa. Specifically, with the assistance of Phase I funding from a Bill and Melinda Gates Grand Challenges Exploration grant, we have developed a novel compact device to measure bioelectrical impedance vector analysis. This device is linked to a smart phone which is programed to show the user body composition and body water components. Further studies are being conducted in the USA and Africa with the goal of early detection of malnutrition and body water changes. This may permit early nutritional intervention in infants, children and pregnant and nursing mothers and improve outcomes.
