This study found no significant difference in physical activity between print and website programs. However, the print program showed a slight increase in activity for inactive participants.

Area of Science:

  • Public Health
  • Health Behavior Change
  • Digital Health Interventions

Background:

  • Mediated physical activity interventions offer cost-effective, large-scale reach.
  • Mail-delivered, stage-targeted programs have successfully increased physical activity.
  • Communication technologies like websites and email present potential for similar interventions.

Purpose of the Study:

  • To compare the effectiveness of a stage-targeted print program versus a website-delivered program for increasing physical activity.
  • To evaluate the impact of different delivery methods on self-reported physical activity levels.

Main Methods:

  • A randomized trial was conducted with 655 Australian university staff (mean age 43).
  • Participants were assigned to either an 8-week print program or an 8-week website program.

  • The primary outcome measured was the change in self-reported physical activity.

    • Main Results:

    • No significant overall increase in physical activity was observed between or within the print and website groups.
    • A significant increase in physical activity was noted among inactive participants in the print group.
    • The website group showed a significant decrease in average weekday sitting time.

    Conclusions:

    • Both print and website programs demonstrated no significant difference in overall effect on reported physical activity.
    • The print program yielded slightly greater effects and higher material recognition.
    • Further research may explore optimal delivery methods for physical activity interventions.
