This article describes one outcome of a randomized controlled trial of community action for cancer prevention. The aims of this article were to (a) explore the effectiveness of a community action program in decreasing community smoking rates in rural Australian towns and (b) describe the relationship between adult smoking quit and uptake rates and demographic variables.
                In 1992, 20 towns were selected for randomization. Community action involved formation of community committees and utilization of access point networks to initiate and maintain intervention strategies. At post-test, outcomes were proportion of "quitters" from a cohort of self-described smokers, proportion of "uptakers" from a cohort of self-described nonsmokers, and "net effect."
                Differences in quit rate, uptake rate, and net effect for intervention compared to control condition favored the intervention in all cases, although mainly nonsignificant. Significantly more male smokers quit in intervention towns than in control towns [7.0% (95% CI: 0.6, 13.5)].
                Given that CART utilized and improved upon strategies argued as effective in the literature, the limited success of the project in reducing adult smoking, considered in combination with COMMIT findings, suggests the need for further innovation in the field.

                A randomized community trial was conducted in 14 Minnesota communities. Seven intervention communities participated in a 32-month community-organizing effort to mobilize citizens and activate the community. The goal was to change ordinances, merchant policies and practices, and enforcement practices to reduce youth access to tobacco. Outcome measures were derived from surveys of students before and after the intervention and from tobacco purchase attempts in all retail outlets in the communities. Data analyses used mixed-model regression to account for the clustering within communities and to adjust for covariates.
                Each intervention community passed a comprehensive youth access ordinance. Intervention communities showed less pronounced increases in adolescent daily smoking relative to control communities. Tobacco purchase success declined somewhat more in intervention than control communities during the study period, but this difference was not statistically significant.
                This study provides compelling evidence that policies designed to reduce youth access to tobacco can have a significant effect on adolescent smoking rates. Schools in many countries undertake programmes for smoking prevention, but systematic reviews have shown mixed evidence of their effectiveness. Most peer-led approaches have been classroom-based, and rigorous assessments are scarce. We assessed the effectiveness of a peer-led intervention that aimed to prevent smoking uptake in secondary schools.
                We undertook a cluster randomised controlled trial of 10 730 students aged 12-13 years in 59 schools in England and Wales. 29 schools (5372 students) were randomly assigned by stratified block randomisation to the control group to continue their usual smoking education and 30 (5358 students) to the intervention group. The intervention (ASSIST [A Stop Smoking In Schools Trial] programme) consisted of training influential students to act as peer supporters during informal interactions outside the classroom to encourage their peers not to smoke. Follow-up was immediately after the intervention and at 1 and 2 years. Primary outcomes were smoking in the past week in both the school year group and in a group at high risk of regular smoking uptake, which was identified at baseline as occasional, experimental, or ex-smokers. Analysis was by intention to treat. This study is registered, number ISRCTN55572965.
                The odds ratio of being a smoker in intervention compared with control schools was 0.75 (95% CI 0.55-1.01) immediately after the intervention (n=9349 students), 0.77 (0.59-0.99) at 1-year follow-up (n=9147), and 0.85 (0.72-1.01) at 2-year follow-up (n=8756). The corresponding odds ratios for the high-risk group were 0.79 (0.55-1.13 [n=3561]), 0.75 (0.56-0.99 [n=3483]), and 0.85 (0.70-1.02 [n=3294]), respectively. In a three-tier multilevel model with data from all three follow-ups, the odds of being a smoker in intervention compared with control schools was 0.78 (0.64-0.96).
                The results suggest that, if implemented on a population basis, the ASSIST intervention could lead to a reduction in adolescent smoking prevalence of public-health importance. This paper describes one outcome of a randomized controlled trial of community action for cancer prevention, Cancer Action in Rural Towns. The aims are to [1] explore the effectiveness of community action in decreasing adolescent smoking in rural Australian towns; and [2] describe the relationship between adolescent smoking rates and demographic variables.
                In 1992, 20 rural Australian towns were selected. Community action involved formation of community committees and utilization of access-point networks to initiate and maintain intervention strategies. Cross-sectional surveys of smoking behaviors for all Year 9 and Year 10 students (13-16 years) in each town were conducted pre- and posttest. The main outcome measure was self-reported smoking in the past 4 weeks. SUDAAN software was used to look at differences between treatment.
                The results showed strong secular trends toward increased adolescent smoking, regardless of treatment group, particularly for females. There was no significant intervention effect.
                Increasing adolescent smoking rates found in this and other studies highlight that the definitive strategy to stem the adolescent smoking epidemic has not been found. Hope may remain for recent legislative strategies, but rigorous evaluation is essential, and compliance with legislation should be carefully monitored.
                Copyright 2001 American Health Foundation and Academic Press. Mass media interventions for reduction of youth cigarette smoking have been recommended based on a broad array of evidence, although few randomized community trials have been reported.
                Four matched pairs of independent media markets were identified; one member of each pair was randomized to receive the intervention. School surveys were conducted in all markets, in 2001 before (n=19,966) and in 2005 after (n=23,246) the interventions were completed.
                Grade 7-12 students from public schools in these eight medium-sized metropolitan areas participated in the summative evaluations; Grades 4-12 students were targeted to receive mass media interventions in four of these markets.
                Four simultaneous campaigns consisting of specially developed messages based on behavioral theory and targeted to defined age groups of racially and ethnically diverse young people were placed in popular TV, cable, and radio programming using purchased time for 4 years.
                Prevalence of youth smoking and psychosocial mediators of smoking.
                No significant impacts of these interventions on smoking behaviors or mediators were found for the overall samples. A positive effect was found for one mediator in subgroups. Among Hispanic participants a marginally favorable effect on smoking prevalence and significant effects on mediators were found. General awareness of smoking prevention TV messages was slightly higher over time in the intervention areas.
                Mass media interventions alone were unable to induce an incremental difference in youth smoking prevalence, probably because of a relatively strong tobacco control environment that included a substantial national smoking prevention media campaign.

                Students from 32 schools in Delhi and Chennai, India, were recruited and randomly assigned to an intervention or control group. Baseline, intermediate, and outcome data were collected from 2 cohorts of 6th- and 8th-grade students in 2004; 14,063 students took part in the study and completed a survey in 2004, 2005, or 2006. The intervention consisted of behavioral classroom curricula, school posters, a parental involvement component, and peer-led activism. The main outcome measures were self-reported use of cigarettes, bidis (small hand-rolled, often flavored, cigarettes), and chewing tobacco and future intentions to smoke or use chewing tobacco.
                Findings showed that students in the intervention group were significantly less likely than were students in the control group to exhibit increases in cigarette smoking or bidi smoking over the 2-year study period. They were also less likely to intend to smoke or chew tobacco in the future.
                School-based programs similar to the intervention examined here should be considered as part of a multistrategy approach to reducing tobacco use among young people in India. Experimental evaluation of comprehensive community wide programme to prevent adolescent tobacco use.
                Eight pairs of small Oregon communities (population 1700 to 13 500) were randomly assigned to receive a school based prevention programme or the school based programme plus a community programme. Effects were assessed through five annual surveys (time 1-5) of seventh and ninth grade (ages 12-15 years) students.
                The community programme included: (a) media advocacy, (b) youth anti-tobacco activities, (c) family communications about tobacco use, and (d) reduction of youth access to tobacco.
                The prevalence of self reported smoking and smokeless tobacco use in the week before assessment.
                The community programme had significant effects on the prevalence of weekly cigarette use at times 2 and 5 and the effect approached significance at time 4. An effect on the slope of prevalence across time points was evident only when time 2 data points were eliminated from the analysis. The intervention affected the prevalence of smokeless tobacco among grade 9 boys at time 2. There were also significant effects on the slope of alcohol use among ninth graders and the quadratic slope of marijuana for all students.
                The results suggest that comprehensive community wide interventions can improve on the preventive effect of school based tobacco prevention programmes and that effective tobacco prevention may prevent other substance use. To test whether high school students' participation in advocacy activities related to the advertising, availability, and use of tobacco in their communities would prevent or reduce their own tobacco use.
                Ten continuation high schools in northern California, randomly assigned to a semester-long program in which students either carried out advocacy activities to counter environmental-level smoking influences in their communities (treatment) or learned about drug and alcohol abuse prevention (control).
                Eleventh and 12th grade high school students; 5 (advocacy) treatment and 5 control schools over 4 semesters from 2000 through 2002.
                Self-reported smoking defined as nonsmokers (those who had never smoked tobacco or those who were former smokers), light smokers (those who smoked <1 pack per week), or regular smokers (those who smoked >or=1 pack per week), and confirmed by carbon monoxide level readings. The following 3 constructs related to social cognitive theory- perceived incentive value, perceived self-efficacy, and outcome expectancies-were assessed.
                There was a significant net change from baseline to the end of the semester (after the intervention) between treatment and control schools for students who were regular smokers, but not for students who were nonsmokers or light smokers. Regular smoking decreased 3.8% in treatment schools and increased 1.5% in control schools (P<.001). Regular smoking continued to decrease at 6 months after the intervention in treatment schools, with a total change in prevalence from 25.1% to 20.3%. Involvement in community-advocacy activities and the 3 social constructs-perceived incentive value, perceived self-efficacy, and outcome expectancies-also showed significant net changes between treatment and control schools (all P values <.01).
                Student engagement in community-advocacy activities that addressed environmental influences of cigarette smoking resulted in significant decreases in regular smoking. To evaluate the impact of a classroom-based, Web-assisted tobacco intervention addressing smoking prevention and cessation with adolescents.
                A two-group randomized control trial with 1,402 male and female students in grades 9 through 11 from 14 secondary schools in Toronto, Canada. Participants were randomly assigned to a tailored Web-assisted tobacco intervention or an interactive control condition task conducted during a single classroom session with e-mail follow-up. The cornerstone of the intervention was a five-stage interactive Web site called the Smoking Zine (http://www.smokingzine.org) integrated into a program that included a paper-based journal, a small group form of motivational interviewing, and tailored e-mails.
                Resistance to smoking, behavioral intentions to smoke, and cigarette use were assessed at baseline, postintervention, and three- and six-month follow-up. Multilevel logistic growth modeling was used to assess the effect of the intervention on change over time.
                The integrated Smoking Zine program helped smokers significantly reduce the likelihood of having high intentions to smoke and increased their likelihood of high resistance to continued cigarette use at 6 months. The intervention also significantly reduced the likelihood of heavy cigarette use adoption by nonsmokers during the study period.
                The Smoking Zine intervention provided cessation motivation for smokers most resistant to quitting at baseline and prevented nonsmoking adolescents from becoming heavy smokers at 6 months. By providing an accessible and attractive method of engaging young people in smoking prevention and cessation, this interactive and integrated program provides a novel vehicle for school- and population-level health promotion.
There is some evidence to support the effectiveness of community interventions in reducing the uptake of smoking in young people, but the evidence is not strong and contains a number of methodological flaws.
