ABSTRACT:
A bioelectricity impedance measuring device includes a contact surface capable of being placed on a part of the body, a gripper which is formed to be easily grasped by a single hand, and electrodes on the contact surface. In addition, the bioelectricity impedance measuring device further includes a malnutrition measuring device which measures malnutrition. An operation and control device measures Phase angle theta and/or an RcXc ratio, and measures a nutrient state. The malnutrition measuring device measures the state of malnutrition from a value of Phase angle theta. A display shows the results of measurement with a bar classified by display of a color. In addition, the operation and control device further measures muscular volume. The operation and control device, by being capable of being provided data or regression, can also measure muscular volume for a child aged 5 or younger or an adult aged 60 or older.
