This study identified six distinct adolescent smoking trajectories, revealing patterns of escalation and stable use, but no quitting trajectory. Predictors like peer influence and mental health varied across these developmental paths.

Area of Science:

  • Adolescent Health
  • Behavioral Science
  • Public Health

Background:

  • Limited research exists on defining adolescent smoking trajectories.
  • Understanding developmental patterns of smoking is crucial for targeted interventions.

Purpose of the Study:

  • To model growth in adolescent smoking and identify distinct, prototypical trajectories.
  • To examine predictors associated with these smoking trajectories across adolescence.

Main Methods:

  • Latent growth mixture modeling was used to analyze smoking escalation as a growth process.
  • Identified trajectories based on rates of change and heterogeneity in smoking patterns.
  • Assessed predictors including substance use, sociodemographics, and mental health across adolescent years.

Main Results:

  • Six distinct adolescent smoking trajectories were identified with high group membership certainty: early/late rapid escalators, late moderate/slow escalators, and stable puffers.
  • No distinct trajectory for adolescent smoking cessation (quitters) was identified.
  • Predictors varied in their association with trajectories, with some influencing trajectory development (e.g., friends smoking) and others resulting from it (e.g., marijuana use).

Conclusions:

  • Adolescent smoking demonstrates diverse developmental pathways, with escalation being a prominent feature.
  • Predictors like peer influence, mental health, and substance use play complex roles in shaping and being shaped by smoking trajectories.
  • Findings highlight the need for tailored prevention and intervention strategies based on identified smoking patterns.
