A School-Based Environmental Intervention to Reduce Smoking among High School Students: The Acadiana Coalition of Teens against Tobacco (ACTT)

A school-based environmental program to reduce adolescent smoking was conducted in 20 schools (10 intervention; 10 control) in south central Louisiana. The 9th grade cohort (n = 4,763; mean age = 15.4 yrs; 51% female; 61% Caucasian; 30-day smoking prevalence at baseline = 25%) was followed over four years for 30-day smoking prevalence with the school as the unit of analysis. Although prevalence decreased in intervention schools and increased in control schools in Year 2 the significant difference between the two groups at baseline was not overcome by the intervention and increases in prevalence were observed in both groups in Years 3 and 4. The higher the percentage of white students in a school the higher the prevalence rates regardless of intervention/control status. Boys' and girls' smoking rates were similar. These outcome data, student feedback and process evaluation provide a basis for continuing to create more innovative adolescent tobacco control programs.
