Conducting nutrition education research in junior high schools: approaches and challenges.

This article describes some of the approaches used and challenges encountered conducting nutrition education research in junior high schools. The Teens Eating for Energy and Nutrition at School (TEENS) study recruited 16 schools and over 3800 seventh graders to participate in an intervention to increase students' intakes of fruits, vegetables, and lower fat foods for the purpose of reducing their future risk of cancer. The TEENS intervention included a classroom curriculum as well as a school environment and family component. This article describes some of the issues faced in the design and implementation of the study including recruiting schools and teens, maximizing the number of students within each intervention school exposed to all components of the intervention, and implementing elements of nutrition education in a classroom setting. The methods used to meet these challenges and the success of the methods attempted are described.
