A new online program effectively identifies and helps prevent eating disorders and weight gain in high school girls. Targeted interventions improved weight and shape concerns for all participants.

Area of Science:

  • Public Health
  • Adolescent Health
  • Behavioral Science

Background:

  • Eating disorders and weight gain are significant health concerns for adolescent females.
  • Early identification and intervention are crucial for preventing these conditions.
  • School-based programs offer a scalable approach to reach this demographic.

Purpose of the Study:

  • To develop and evaluate a model for the simultaneous prevention of eating disorders and weight gain.
  • To utilize an online platform for risk assessment and intervention delivery.
  • To tailor interventions based on individual risk profiles.

Main Methods:

  • 174 female 10th graders participated in the study.
  • An online assessment identified participants' risk for eating disorders and/or overweight.

  • Participants were assigned to one of four tailored interventions based on their risk level.

    • Main Results:

    • The risk assessment algorithm categorized students into no-risk, eating disorder risk, overweight risk, or both risks.
    • A majority of at-risk students (56% of eating disorder risk, 50% of overweight risk) opted for targeted curricula.
    • All intervention groups showed significant improvements in weight and shape concerns.

    Conclusions:

    • An internet-delivered program can effectively assess risk for eating disorders and weight gain in adolescent females.
    • This model allows for simultaneous universal and targeted interventions within a classroom setting.
    • The program demonstrates potential for widespread implementation in schools to promote adolescent health.
