Nursing student....nursing theory help

[yatyu]

Hello..I am doing a community project about promoting children 's (10-14 yrs) awareness about obesity and the importance of exercise. The mentor requires me to apply nursing theories in the project. Could you make some suggestions to me? I've found those theories for 1 wks already but still can't apply those to the objective of the project. Please help me.....the deadline is next week......Thanks a lot!!!
