Cost Effectiveness of Community-Based Physical Activity Interventions

Conceptual overview of the CDC MOVE model. Illustration of the 10-state Markov process represented as a state-transition diagram. In this process, circles represent possible health states, and arrows represent allowed transitions among these discrete health states. In each cycle of the Markov model, transition probabilities denote the likelihood with which people within a particular health state will stay in that state (represented by the tight curvilinear arrows to and from a single circle); transition to a new health state; or die. Death is an absorbing state from which no future transitions are possible. The output from the Markov process is depicted by the box; a running tally of the total costs and quality-of-life benefits generated during each cycle as a result of being in a series of health states over time.
