BMI is based on height and weight only, but the BVI application automatically measures BMI, waist circumference and waist-hip ratio in addition to highly sophisticated 3D volumetric and body composition analysis. It is projected that scientific and technical development of BVI may take a similar period as with BMI, so 2020 is the current projected date for adoption and delivery on the scale required. By 2013 six scientific and seven academic institutions had been involved in the evaluation and validation of BVI as a potential new health risk measurement and indicator, which has been ongoing since March 2007.
