I would also add that much of the research that has been funded is still relatively recent research, which Diane pointed out, and the huge spike in research is still relatively new. Some of the research is ongoing.
I think many of the things that we've talked about here today in terms of the environmental issues around obesity and the school situation, with soft drinks in schools, etc., have been brought to our attention through some of the research that's been funded. It is starting to have an impact on policy. As Sally said, we now have to really measure the interventions of those policies that take place.
A lot of the research that has come forward has started to describe the problem. Policy makers are starting to act. Our data infrastructure in the country is such that we are only really able to do descriptive research. It's very difficult for us to get at a lot of the processes under way, given the limited data sources we have.
