A multi-level examination of school programs policies and resources associated with physical activity among elementary school youth in the PLAY-ON study

摘要

BackgroundGiven the decline in physical activity (PA) levels among youth populations it is vital to understand the factors that are associated with PA in order to inform the development of new prevention programs. Many studies have examined individual characteristics associated with PA among youth yet few have studied the relationship between the school environment and PA despite knowing that there is variability in student PA levels across schools.
