The present invention is configured so as to: continuously estimate spinal disc pressure in a wearer on the basis of the weight of an object, the height and weight of the wearer, and the trunk angle of the wearer; and predict the risk that symptoms of lower back pain will arise in the wearer during a work period involving heavy work for handling the object, while chronologically measuring an elapsed time for each segment in which the spinal disc pressure corresponds to a load level.
