“Impact of the Boston Active School Day Policy to Promote Physical Activity Among Children”

A study by HPRC’s Dr. Angie Cradock, Jessica Barrett, and Dr. Steven Gortmaker found that Active School Day implementation increased student moderate-to-vigorous physical activity levels and decreased sedentary time during school at modest cost.

The study took place in six elementary schools with three matched pairs and included 455 consenting fourth- and fifth-grade students in Boston, Massachusetts, from February to June 2011.
