Pathways is a school-based obesity prevention program for American Indian children. The study aims to reduce body fat through curriculum, physical activity, and family involvement.

Area of Science:

  • Public Health
  • Pediatric Obesity Prevention
  • Community Health Interventions

Background:

  • Childhood obesity is a significant public health concern, particularly in American Indian communities.
  • Primary prevention strategies are crucial for long-term health outcomes.
  • School-based interventions offer a promising platform for reaching children.

Purpose of the Study:

  • To design and implement a randomized, school-based intervention (Pathways) for the primary prevention of obesity in American Indian children.
  • To evaluate the efficacy of the intervention in reducing body fat percentage.

Main Methods:

  • Randomized controlled trial involving 41 schools serving American Indian children.
  • Intervention components include health promotion curriculum, physical education, school meals, and family involvement.
