Figure 1. Public health model illustrating the multifactorial model etiology of obesity. The traditional public health of disease transmission applied to obesity etiology. In this model, the impact of the agent (positive energy balance) can be modified by a number of host (specific to the individual) and environment (specific to collective behaviors or conditions) factors. In addition, a variety of vehicles/vectors are responsible for transmitting the causal agent.
