A method for improving the health status of members of an entity by using a program in which members may enroll is provided. The method includes notifying members a pool of rewards available to those who enroll in the program. For each enrolled member, a target physiological condition is established and successive physiological measurements related to the condition are obtained over a period of time. The target physiological condition and the successive physiological measurements are stored in a digital computer system and a computer process is used to determine and store a score of such member's proximity to the target physiological condition based on each such measurement. An award from the pool to one or more enrolled members is granted based on their scores at the end of the period.
