The First Twenty for Volunteer Firefighters assessed the efficacy of an internet-based firefighter tailored health and wellness program for volunteer firefighters using a cluster randomized controlled trial (CRCT)

  • TF20 included nutrition, fitness, and stress management education and activities including prescribed messages, goal setting, resource materials (recipes, exercise plans, etc.), and personalized health coaching from a trained firefighter
  • Assessed the dietary intake, physical activity, anxiety, stress depression, smoking, occupational injuries and sociodemographic factors pre and post
  • Outcomes include BMI, percent body fat, waist circumference, diet, and physical activity
  • 6-month intervention including 5 treatment and 5 wait-list control volunteer fire departments across the nation including over 400 firefighters
