Abstract: A pedometer is provided for use by a pregnant woman. Embodiments include a pedometer having a number-of-activity step acquisition unit that acquires the number of activity steps taken by the pregnant woman, an activity energy consumption calculation unit that calculates activity energy consumption caused by the number of activity steps, and a proper energy consumption storage unit that stores proper energy consumption for the pregnant woman. A comparison and assessment unit compares the activity energy consumption with the corresponding proper energy consumption and assesses the activity energy consumption of the pregnant woman. A comparison and assessment result output unit outputs the result of the comparison and assessment.

Abstract: Disclosed is a pedometer for use with a pregnant woman, comprising: a fat deposition related factor acquisition unit; a term-after-pregnancy acquisition unit; a number-of-activity step acquisition unit; an activity energy consumption calculation unit; a proper energy consumption storage unit; a comparison and assessment unit; and a comparison and assessment result output unit. According to the present invention said fat deposition related factor acquisition unit acquires a factor related to fat deposition of the pregnant woman, said term-after-pregnancy acquisition unit acquires a term that has elapsed after pregnancy, and said number-of-activity step acquisition unit acquires the number of activity steps taken by the pregnant woman. Furthermore, said activity energy consumption calculation unit calculates activity energy consumption caused by said number of activity steps acquired, and said proper energy consumption storage unit stores proper energy consumption for the pregnant woman.
