title: Twelve-Month Effects of the COPE Healthy Lifestyles TEEN Program on Overweight and Depressive Symptoms in High School Adolescents.
abstract: BACKGROUND
  We evaluated the 12-month effects of the COPE (Creating Opportunities for Personal Empowerment) Healthy Lifestyles TEEN (Thinking, Emotions, Exercise, Nutrition) program versus an attention control program (Healthy Teens) on overweight/obesity and depressive symptoms in high school adolescents.
  
  
  METHODS
  A cluster randomized controlled trial was conducted. Participants were 779 culturally diverse adolescents in the US Southwest. COPE is a cognitive-behavioral skills-building intervention with 20 min of physical activity integrated into a health course and taught by teachers once a week for 15 weeks. Outcome measures included body mass index (BMI) and depressive symptoms.
  
  
  RESULTS
  COPE teens had a significantly lower BMI at 12 months (F(1,698)  = 11.22, p = .001) than Healthy Teens (24.95 versus 25.48). There was a significant decrease in the proportion of overweight and obese COPE teens from baseline to 12 months (χ(2)  = 5.40, p = .02) as compared with Healthy Teens. For youth who began the study with extremely elevated depressive symptoms, COPE teens had significantly lower depression at 12 months compared with Healthy Teens (COPE M = 42.39; Healthy Teens M = 57.90); (F(1 ,12)  = 5.78, p = .03).
  
  
  CONCLUSIONS
  COPE can improve long-term physical and mental health outcomes in teens.
