Stay away from tobacco: a pilot trial of a school-based adolescent smoking prevention program in Beijing, China.

A quasiexperimental study was conducted to explore the efficacy of the program Stay Away from Tobacco (SAFT). Participants-from 11 classes with 381 students total in grades 7, 8, 10, and 11-were assigned by class to three groups (intervention group T with school teachers delivering the program, intervention group R with researchers delivering the program, and comparison group C). Data were collected at baseline, immediately after the intervention, and 6 months after the intervention. Self-reported smoking was the outcome measure. The 30-day smoking prevalence in group C increased from 4% at baseline to 10% at the 6-month follow-up, whereas this rate declined from 11% to 6% in group T, and from 9% to 1% in group R. For group T, the odds ratio (for 30-day smoking) and the regression coefficient (for indexed number of cigarettes smoked) assessing interactions between intervention and time were 0.20 (p < .001) and -.1605 (p < .05), respectively. The same statistics for group R were 0.09 (p < .001) and -.2406 (p < .01), respectively. The predicted smoking rate declined by 19% from baseline to 6-month follow-up in group T (11.5% vs. 9.3%), and the same rate declined by 26% in group R (11.1% vs. 8.2%). The results from this pilot trial suggest that SAFT can reduce cigarette smoking among middle and high school students through its effect on improving these students' refusal skills and changing their perceived mental and physical values from smoking. A full-scale evaluation is recommended.
