OBJECTIVES: The purpose of this study was to determine the efficacyof a college-based smokeless tobacco cessation interventiontargeting college athletes. METHODS: Sixteen colleges were matchedfor prevalence of smokeless tobacco use in their combined baseballand football teams and randomly assigned within college pairsto the intervention or the control group. One-year prevalenceof cessation among smokeless tobacco users was determined byself-report of abstinence for the previous 30 days. Differencesbetween groups were analyzed in a weighted version of the Fisher1-sided permutation test for paired samples after adjustmentfor significant predictors of quitting other than the intervention(i.e., smokeless tobacco uses per week and most frequently usedbrand). RESULTS: Cessation prevalences were 35% in the interventioncolleges and 16% in the control colleges when subjects withunknown quit status were defined as nonquitters. After adjustmentfor other significant predictors of quitting, the differenceof 19% increased to 21%. The intervention effect increased withlevel of smokeless tobacco use. CONCLUSIONS: This interventionwas effective in promoting smokeless tobacco cessation, especiallyamong those who were more frequent users.
