Area of Science:

  • Behavioral Science
  • Public Health
  • Clinical Intervention

Background:

  • Overweight and obesity are significant global health challenges.
  • The HEALTHI program is a 12-week intervention utilizing mental imagery and implementation intentions.
  • Text messages will be evaluated for their potential to enhance intervention effects.

Purpose of the Study:

  • To assess the effectiveness of a theory-based weight-loss intervention.
  • To improve dietary intake and physical activity in overweight and obese individuals.
  • To determine if text messages augment intervention outcomes.

Main Methods:

  • Randomized controlled trial with three arms: psycho-education plus techniques, psycho-education plus techniques and text messages, and psycho-education control.
  • Intervention delivered via video presentation for broad applicability and cost-effectiveness.
  • Primary outcome: body weight. Secondary outcomes: biomedical, psychological, and behavioral measures at 6 and 12 weeks.

Main Results:

  • Hypothesized statistically significant changes in primary and secondary outcomes for intervention groups compared to control.
  • Anticipated enhanced effects in the group receiving text messages.
  • Analysis will control for baseline values.

Conclusions:

  • The HEALTHI program is a theory-based intervention designed to reduce weight and improve related outcomes in adults.
  • The intervention is designed for real-world applicability and potential integration into existing practices.
