Prediction device, prediction method, and prediction program

A prediction device for predicting a skeletal muscle mass of a subject, comprising:

• a computing device;
• and
• a communication device connected to the computing device in a communicable manner,
• wherein the communication device is configured to
• acquire a first measurement value of advanced glycation end-products of the subject a plurality of times periodically at a first interval, and
• acquire a second measurement value of the skeletal muscle mass of the subject periodically at a second interval longer than the first interval, and
• wherein the computing device calculates prediction information regarding a prediction value of the second measurement value, based on the first measurement values acquired a plurality of times and the second measurement value.
