Method to determine the arterial stiffness of an individual user (U) standing on a personal electronic scale (1) having a top surface with at least three conductive pads (11-13) on one of the leftorright side of the scale,/a/- acquiring weight variations, and extracting therefrom a ballistocardiogram (21) of the users heart beat,/b/- acquiring impedance plethysmography signals across one of the foot of the user, and extracting therefrom a blood pulse signal (22) at the foot,/c/-calculating a time delay (DT) between the heart beat and the blood pulse signal arriving at the foot,/d/ deducing therefrom a value of the arterial stiffness of the user
