Abstract: To appropriately assess lifestyle relating to metabolic syndrome. An ultrasonic probe captures an image of an abdomen of a subject and outputs a tomographic image of the abdomen. A feature assessing unit includes a learning model and a measuring unit, and outputs assessment index data indicating respective features of at least a subcutaneous fat layer, a visceral fat layer and right and left rectus abdominis muscle among living body portions visualized in the tomographic image. A measure presenting unit selectively presents one of a plurality of measure patterns obtained by systematically classifying measures concerning lifestyle, in accordance with the assessment index data.
