Method to determine the arterial stiffness of an individual user (U) standing on a personal electronic scale having a top surface with at least three conductive pads on one of the left or right side of the scale,/a/—acquiring weight variations, and extracting therefrom a ballistocardiogram 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 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
