Health in Motion

Childhood and Teenage Obesity Prevention

Health in Motion is an obesity prevention program focusing on three behaviors critical for healthy energy balance:

  • Increasing physical activity
  • Eating more fruits and vegetables
  • Reducing TV time

The program includes videos and interactive animations.

In a randomized trial funded by the National Heart, Lung, and Blood Institute, the intervention group, relative to control, was more likely at three months follow-up to meet national guidelines for physical activity, fruit and vegetable consumption, and TV viewing. These effects were relatively stable for the treatment group at 12 months follow-up. A separate study funded by the National Institute on Drug Abuse replicated these findings and demonstrated that the intervention also reduced uptake of cigarette and alcohol use.

Health in Motion

Development and testing of this program was supported by SBIR grant 2 R44 HL074482-02 from the National Heart, Lung, and Blood Institute.

Obesity Prevention at the Elementary School Level


Assessments of the Transtheoretical Model constructs (stage of change, pros and cons, self-efficacy, and processes of change) have been developed and validated for elementary school students for physical activity, fruit and vegetable consumption, and limited TV viewing. These assessments are available for purchase.

Family Guide

This short guide offers parents and guardians information on critical behaviors for promoting energy balance and preventing obesity among youth including physical activity, fruit and vegetable consumption, and limited TV viewing. Family members are offered guidance on assessing how ready their child is to meet national guidelines for these behaviors. Tips for encouraging healthy lifestyles at home are offered.


Pro-Change staff is available to conduct half day trainings on incorporating the Transtheoretical Model of Behavior Change into youth wellness programs and curriculum. Background on the model, information on assessing the stage of readiness of the youth to do the target behaviors, and ideas for incorporating stage-matched messages and activities into your program are offered.
