Doing a research review paper on childhood obesity

Pretty self explanatory really!

Doing a 2000 word essay on ways that the UK can tackle childhood obesity (prevention and treatment). Does anyone here know of any good recent research into the topic that might be worth looking into? It's a really interesting subject area! I've looked into things such the Change4Life campaign, and HENRY (Health Exercise Nutrition for the Really Young), and currently I am trying to find some papers regarding how childrens' modelling of parent and peer eating behaviours affect their own.

Any comments? Suggestions? Just thought it might spark a bit of conversation in the MFP community!
