Primary Outcome Measures:
  • Smoking prevalence of adolescents in each group [ Time Frame: six years ]
    We will compare the smoking prevalence of adolescents in each group at six years against the usual null hypothesis of no difference between groups. We will use the Chi-squared test, taking into account the "variance inflation factor" of the adolescent cluster and intraclass correlation coefficient.
