Smokeless tobacco cessation cluster randomized trial with rural high school males: intervention interaction with baseline smoking.

INTRODUCTION: Adolescent males in rural areas use smokeless tobacco (ST). We assessed the efficacy of a school-based nurse-directed ST intervention among rural high school males. METHODS: Study high schools were randomly selected from a public high school list of California rural counties. Consenting high schools were stratified by school size and randomly assigned within strata to intervention or no-intervention groups. After gaining parental consent, male students completed baseline and 1-year follow-up questionnaires. The intervention included peer-led educational sessions and an oral exam by the school nurse who also provided brief tobacco cessation counseling. We used binary generalized estimating equation (GEE) models accounting for clustering within schools to test no difference between groups after adjusting for year in high school using both completers only and multiple imputation for those lost to follow-up. Subgroup analyses assessed Baseline Factor x Group interaction in GEE models. RESULTS: Twenty-one rural counties (72%), 41 randomly selected high schools (56%), and 4,731 male students (50%) participated with 65% retention. Nonsmoking ST users in the intervention group were significantly more likely to stop using ST at follow-up than those in the no-intervention group; there was no intervention effect among baseline ST users who also smoked. A higher percentage of baseline nonsmoking ST users reported smoking at follow-up than baseline non-ST-using smokers who reported using ST. DISCUSSION: A school-based nurse-directed ST cessation program was efficacious among rural nonsmoking ST-using high school males. The potential program reach holds significant public health value. Baseline ST use facilitated smoking at follow-up.

Development and evaluation of a tobacco cessation motivational program for adolescents based on physical attractiveness and oral health.

PURPOSE: Little is known about how to motivate youth to participate in smoking cessation programs. This paper reports an investigation of the feasibility and acceptability of an intervention that used vanity and oral health issues associated with tobacco use to motivate adolescent tobacco users to enter a school-based tobacco cessation program. METHODS AND MATERIALS: Sixty-four continuation high school students aged 14 to 19 (31% female) and living in rural California participated in a youth-oriented, vanity and oral health-focused intervention designed to motivate tobacco users to join a six-week tobacco cessation group. RESULTS: Following the intervention, 21 of 37 (57%) regular smokers signed up for the cessation program. Of these smokers, seven (33%) did not indicate on the baseline questionnaire any desire to quit smoking. Of the 21 smokers who signed up to participate in the cessation program, 16 (76%) actually participated (10 males and six females), eight (50%) completed all treatment sessions, and four (25%) reported that they quit smoking at the end of the program. CONCLUSIONS: Overall program evaluations were very favorable. Findings were interpreted to provide support for the feasibility and acceptability of using physical appearance and oral health-oriented programs to motivate adolescent tobacco users to enter school-based cessation programs. Further study is needed to determine the effectiveness of such programs.
