Chapter 1

Lecture Notes

On the next two slides we're going to compare the top 10 leading causes of death in 2007, on this slide, to the top 10 leading causes of death in 1900, and what I want you to see is that the types of diseases that we're dying from today are much different than they were in 1900. So, for example, here in pink you can see all of the reasons, leading causes of death for which sedentary lifestyle plays a role. That doesn't mean it's the only thing that contributes to these types of deaths, but that sedentary lifestyle could play a role. In the top three here you see heart disease, cancer and cerebrovascular diseases; stroke would be an example of that. So we have these top 3 diseases where sedentary lifestyles, people sitting too much, not being active, are playing a role in the leading causes of death. Very few of these top causes of death are completely unrelated to physical activity, so only 3 of these top 10 are unrelated to leading a sedentary lifestyle.
