Secondary Outcome Measures:
  • Mean lean and fatty body mass proportions: measured by portable electrical bioimpedance bean [ Time Frame: one year ]

Estimated Enrollment: 600
Study Start Date: February 2010
Study Completion Date: December 2010
Primary Completion Date: November 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: reducing beverages and sugar and increase physical activity
reduction of beverages and sugar and increasing physical activity
Behavioral: lifestyle

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
