Computer simulation models are opening up significant new possibilities for quantitative analysis in the area of health. This presentation briefly reviews two examples at opposite ends of the complexity spectrum—the two short stories—and then goes into more detail for a third example—the tale. The first, a theoretical model, seeks to understand key factors accounting for observed patterns of health inequality, especially in Canada and the US. The second briefly introduces one of the applied cancer control policy models being developed under the auspices of the Canadian Partnership Against Cancer, specifically HPV and cervical cancer. The third and longer tale describes HealthPaths, a computer model based on the longitudinal National Population Health Survey, which is designed to estimate, in a multifactorial framework, the relative quantitative importance of various behavioural and social factors on Canadians' health-adjusted life expectancy. Perhaps surprisingly, obesity is the least important of the factors examined.
