Title: Studies to Treat Or Prevent Pediatric Type 2 Diabetes (STOPP-T2D) Middle-School Based Primary Prevention Trial (HEALTHY)
Brief Summary: HEALTHY was a primary prevention trial conducted in 42 middle schools at 7 locations across the US to impact risk factors for type 2 diabetes in adolescents. Students were recruited at start of 6th grade (fall 2006) and followed to end of 8th grade (spring 2009). Half of the schools were randomized to receive an intervention that integrated four components: the school nutrition environment, physical education class activities, behavior change initiatives, and educational and promotional communications activities.
