1. A method comprising:

  • generating an arterial stiffness measurement byin a body scale including and integrating a first sensor, using the first sensor to capture, while a user is standing on the body scale, a BCG (ballistocardiogram) or hand-to-hand impedance cardiogram T1 signal that is indicative of mechanical movement of blood through a user'"'"'s aorta and that is indicative of a proximal cardiogram timepoint or a T1 carotid timepoint;

    using a second sensor to detect a pressure pulse at a location sufficiently distal to the user'"'"'s aorta to allow a determination of arterial pulse wave velocity; and

    using logic circuitry to determine the arterial pulse wave velocity by calculating timings corresponding to the T1 signal and a timing of the pressure pulse.
