The purpose of this paper is to examine relevant literature that demonstrates the interactions among built environments and children's sedentary behaviors from a social ecological perspective. An overview of the existing body of knowledge relating to children's sedentary behavior will be shared. A social ecological theoretical framework will be used to investigate how built environments in home, school, and neighborhood settings may impact children' sedentary behaviors. Finally, a synthesis of emerging research and implications for practice along with recommendations will be highlighted to demonstrate how children's sedentary behaviors can be altered by modifying built environments in home, school, and neighborhood settings.
