Communities Creating Healthy Environments is a national program of the Robert Wood Johnson Foundation (RWJF) that aims to prevent childhood obesity by increasing access to healthy foods and safe places to play in communities of color. The program will advance RWJFs efforts to reverse the childhood obesity epidemic by 2015 by supporting diverse, community-based organizations and federally chartered tribal nations in the development and implementation of effective, culturally competent policy initiatives to address childhood obesity at the local level. Through this call for proposals, RWJF will award grants for policy advocacy to improve food and recreation environments in up to 10 communities at high risk for obesity.
