title: Does adolescent weight status predict problematic substance use patterns?
abstract: OBJECTIVE
  To identify underlying patterns of cigarette smoking, alcohol use, and marijuana use in young adulthood, and ascertain whether adolescent overweight or obesity status predicts problematic substance use patterns.
  
  
  METHODS
  The study included 15,119 participants from the National Longitudinal Study of Adolescent Health (Add Health) at Wave 1 (11-19 years) and Wave 3 (18-26 years). Latent class analysis was conducted.
  
  
  RESULTS
  Participants were classified into a Low Substance Use (35%), Regular Smokers (12%), High-risk Alcohol use (33%), or High Substance Use (20%) class. Overweight/obese adolescents had a greater likelihood of belonging to the Regular Smokers class.
  
  
  CONCLUSIONS
  Overweight/obese adolescents are at higher risk of engaging in regular cigarette smoking without problematic alcohol or marijuana use.
