      Youth Tobacco Prevention Initiative?

AB  - INTRODUCTION: No previous studies document the effects of both comprehensive 
      tobacco control and its defunding on youth smoking. This study tests the effect 
      of the youth-focused Minnesota Youth Tobacco Prevention Initiative (MYTPI) and 
      its shutdown on youth smoking and determines whether these effects differed by 
      age. METHODS: The Minnesota Adolescent Community Cohort is a population-based, 
      observational study designed to evaluate the MYTPI. The sample included cohorts 
      of youth aged 12-16 years at baseline in Minnesota (N = 3,636) and a comparison 
      group in six other Midwestern states (n = 605). Biannual surveys assessed youth 
      smoking from October 2000, 5 months after the MYTPI launch, through October 2005, 
      2 years postshutdown. Adjusted piecewise linear trajectories predicted smoking 
      stage (measured on a 1-6 continuum) comparing Minnesota with a comparison group 
      during the MYTPI (Slope 1) and postshutdown (Slope 2) for each baseline age 
      cohort. Analysis then compared baseline age cohorts with each other by centering 
      their intercepts on age 16. RESULTS: Neither slope of smoking stage differed 
      between Minnesota and comparison groups, showing no period effects for the MYTPI 
      or shutdown. However, younger cohorts, with early teen experience of MYTPI, 
      smoked less than older cohorts by the same age. Mean smoking stage at age 16 
      differed by almost a half stage from the youngest (2.04) to the oldest (2.46) age 
      cohort. DISCUSSION: The study offers no evidence of period effects for the MYTPI 
      or its shutdown. Design limitations, national or continued post-MYTPI statewide 
      tobacco control efforts, or program flaws could explain the findings.
