    Abstract: A health condition determining device accumulates data measured or input by an evaluation subject for each index of a plurality of items including a lifestyle index, which is an index related to body activity or lifestyle habit, and a biomarker, which is an index related to physiological state of the body. The health condition determining device then selects one or a plurality of biomarkers that lowers the evaluation of the health condition of the evaluation subject as a problematic index, extracts one or a plurality of lifestyle indices having the highest correlation with the problematic index as an improvable factor by comparing accumulated past data of the lifestyle index and the biomarker, and displays the improvable factor along with the evaluation of the health condition of the evaluation subject.

  • Patent number: 7813794
    Abstract: In a body fat measuring apparatus, a constant electric-current is flowed between hand electric-current electrodes and leg electric-current electrodes. From two detected voltages generated between an annular-shaped voltage electrode placed on an abdominal portion and two voltage electrodes placed at the both sides of a lumbar portion, two abdominal impedances are determined. Two electric-current electrodes and two voltage electrodes are placed such that they are spaced apart by a small interval from one another at an umbilicus portion. A constant electric current is flowed between the two electric-current electrodes and the impedance in the vicinity of the subcutaneous of the abdominal portion is determined from the detected voltage generated between the two voltage electrodes. From the two abdominal impedances, the impedance in the vicinity of the subcutaneous of the abdominal portion, and the input physique information, a viscera impedance is calculated.
