Predicted menstruation start date calculation apparatus, program, and body analysis apparatus

A non-transitory computer readable medium having stored thereon a program for causing a computer to execute:

• acquiring a number of menstrual cycle days and a number of high temperature phase days over a plurality of menstrual cycles of a woman;
• based on whether or not the number of menstrual cycle days of the woman falls within a predetermined range and whether or not the number of high temperature phase days of the woman falls within a predetermined range, performing classification into a specific type indicating that the number of menstrual cycle days is unstable and the number of high temperature phase days is stable, and into one or more types other than the specific type;
• and
• if the type into which the woman is classified by the type classification unit is the specific type, calculating a predicted menstruation start date by adding a number of days obtained based on the number of high temperature phase days to the woman's most recent ovulation date, and if the type into which the woman is classified by the type classification unit is a type other than the specific type, calculating the predicted menstruation start date based on the woman's most recent menstruation start date and the number of menstrual cycle days.

A body analysis apparatus configured to analyze a body, wherein

• the body autonomously transitions between a plurality of phases that each indicate an internal state of the body, and
• a plurality of types relating to the transition between the phases exist,
• the apparatus comprising:
• a model storage unit configured to store a model corresponding to a type for each type relating to the transition between the phases;
• an obtaining unit configured to obtain observation data by observing the transition between the phases of the body;
• a detection unit configured to detect a type relating to the transition between the phases of the body based on the observation data;
• and
• an analysis unit configured to read out the model corresponding to the type detected by the detection unit from the model storage unit and analyze the body using the read-out model.
