Claim:
1. A measurement device comprising: a housing that has an attached biosensor that includes a reagent selectively responding to a specific analyte in a biological fluid, and is configured so as to be carried by a user; an analyte measurer that measures a concentration of the specific analyte with a biosensor; a motion measurer that measures a motion level of the housing based on vibration applied to the housing, wherein the motion measurer determines an orientation of the housing with respect to a horizontal and, based upon the determined orientation, measures the vibration applied to the housing after a predetermined time period; a living activity level calculator that calculates a living activity level of the user in terms of intensity of motion by a living activity of the user, based on the motion level of the housing measured by the motion measurer; a recorder that records the living activity level calculated by the living activity level calculator; and a controller that is programmed to detect a plurality of living activity levels recorded in the recorder greater than a first threshold, used to identify a moving activity in daily life to identify an interval between two of the moving activities and the length of the interval to identify a non-moving activity, to determine a meal event if the interval is longer than a predetermined time to identify meal time, to determine whether a time of the measurement of the concentration of the specific analyte performed by the analyte measurer is before the meal event or after the meal event, and to record the concentration of the specific analyte measured by the analyte measurer before the meal event and the concentration of the specific analyte measured by the analyte measurer after the meal event in a distinguishable state in the recorder.
