Pilot Program Fails to Boost Physical Activity Among Teen Girls, Spring Weather Works Better

Researchers at the University of Michigan School of Nursing developed a 12-week computer-based interactive intervention to encourage adolescent girls to be more physically active, and tested it among girls in two low-income areas.

Key Findings

  • There was no significant difference between the control and intervention groups in the amount of physical activity they engaged in during the project.
  • Both groups reported a significant increase in days per week of physical activity.
  • The project director attributed this increase in part to a seasonal variation in activity: the pretest took place in the winter and the post-test in the spring.
