Our Health In Motion adolescent obesity prevention program is targeted at teens and focuses on three areas:
- Increasing physical activity
- Eating more fruits and vegetables
- Reducing TV time
This online program includes voice-overs read by teens, ten full-motion videos of teens working through exercise, eating and TV time issues, and interactive Flash animations to keep students’ interest.
Background
Development of this program was supported by grant R43 HL074482 from the National Institutes of Health (NHLBI). An effectiveness trial conducted in schools in Tennessee, New York, Massachusetts, and Rhode Island was completed in December 2007. Outcomes will be available during summer 2008.

Abstract: Interactive technologies have emerged as a promising means for developing and disseminating health behavior change interventions. Interactive health behavior change programs are most often computer-delivered via the World Wide Web, a CD-ROM/DVD, or a stand-alone kiosk. There are many benefits of programs using these technologies. They allow the incorporation or rich media such as audio, animated graphics, and video. On-screen assessments and programming allow for immediate feedback with extensive opportunities for tailoring to participant responses. The embedded interactivity gives the user an active role with more control over their participation. Users enjoy the appeal these features offer and the flexibility of engaging in the program at their convenience. Researchers and program implementers appreciate the fidelity to treatment offered with consistent and reliable feedback delivered to participants. With improved program retention, wider reach, and less reliance on staff for delivery, interactive technologies offer a cost-effective means of delivering behavior change interventions. They are acclaimed by researchers to be an innovative, powerful, and promising way of improving the efficacy and dissemination of behavior change intervention.

Abstract:
Backqround: Curbing the epidemic of childhood and adolescent obesity requires impacting multiple behaviors. This article examines the interrelationships of physical activity, fruit and vegetable consumption, and limiting television time among elementary, middle, and high school students.
Methods: Nationwide samples of students in grades 4 through 12 (n=4,091) completed self-administered questionnaires assessing Transtheoretical Model (TTM) constructs and behavioral indicators for physical activity, fruit and vegetable consumption, and limiting television time. Analyses were conducted to compare the prevalence of students at-risk for the target behaviors across the age groups and to examine the interrelationships of the target behavior risks.
Results: Across the three age groups, physical activity and fruit and vegetable consumption declined, while limiting TV time increased. In addition, high school students had the greater number of behavioral risks. Across all three samples, being at-risk for one behavior almost always significantly increased the odds of being at-risk for another behavior.
Conclusion: The findings of this study provide further evidence for the need for early promotion of healthy lifestyle behaviors. The relationships among the target behaviors in three samples strongly support a multiple behavior approach for obesity prevention. TTM-based tailored interventions are now being used to address multiple behaviors without overwhelming students.

Abstract: This article describes the development and pilot testing of a computer-based, multiple-behavior obesity prevention program for adolescents. Using the Transtheoretical Model as a framework, this intervention offers individualized feedback based on readiness to engage in physical activity, to consume fruits and vegetables, and to limit television viewing. Focus groups and interviews with students, teachers, school administrators, and experts guided the development. Forty-five students participated in a baseline intervention session and completed a 16-item acceptability measure. Ratings were positive, with item means ranging from 3.60-4.75 on a 5-point scale. Student responses to open-ended questions aided in the enhancement of the intervention, for which an effectiveness trial begins in September 2006. This formative work demonstrated the acceptability of this school-based intervention approach, which can be promoted and prescribed by school nurses. Further, if found effective, it can be disseminated as an efficient, low-cost, population-based approach designed to address the epidemic of obesity.
