PROBLEM TO BE SOLVED: To provide a disease prediction method capable of predicting the onset of disease from a disturbance in a daily life rhythm, imposing only a small burden on a subject for measurement.SOLUTION: A process step S504 for predicting the onset of disease or disorder of a user is executed in which user activity information on a state of an activity performed by the user and a time zone in which the activity is performed is applied to disease-related information indicating correlation between subject activity information on states of activities performed by at least a plurality of subjects acquired beforehand and time zones in which the activities are performed, and subject state information on body conditions of the subjects.SELECTED DRAWING: Figure 5COPYRIGHT: (C)2018,JPO&INPIT【課題】測定にかかる被験者の負荷が小さく、かつ日常的な生活リズムの乱れから疾病の発症を予測することができる疾病予測方法を提供する。【解決手段】少なくとも、予め取得された複数の被験者が行った活動の状況及びこの活動が行われた時間帯に関する被験者活動情報と、被験者の身体の状態に関する被験者状態情報と、の関連性を表す疾病関連情報に、利用者が行った活動の状況及びこの活動が行われた時間帯に関する利用者活動情報を適用して利用者が発症する疾病または障害を予測する工程ステップS504を実行する。【選択図】図5
