A CPU of a health management apparatus functions as an acquisition unit, a first derivation unit, and a screen output control unit. The acquisition unit acquires a body-fat percentage which is an obesity parameter indicating the degree of obesity of a target pet and bone density which is a bone parameter indicating the degree of bone strength of the target pet. The first derivation unit derives health conditions of the target pet on the basis of a correlation between the body-fat percentage and the bone density. A screen output control unit performs control to output a medical examination result display screen on which the health conditions are displayed.
