reduction of beverages and sugar and increasing physical activity
Based on beliefs and behaviors of children sections of education will be delivered via classroom activities.
Activities will be facilitated by trained research assistants. Printed instructions and orientations on the facilitation process will support the assistants' efforts. The activities will require 20 to 30 minutes, and teachers will be encouraged to reiterate the message during their lesson. The goal is to promote ten one-hour sessions of activity for each class.
Children will also be stimulated to increase everyday activities such as walking and playing games at home and school. Also, activities with parents and family members such as walking around the neighborhood on weekends will be promoted.
|No Intervention: control -no intervention|
Specific objectives are:
