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.
                Copyright American Health Foundation and Academic Press. This study tested the hypothesis that adoption and implementation of local policies regarding youth access to tobacco can affect adolescent smoking.
                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. Skills intervention to prevent cigarette smoking was evaluated with 689 adolescents. At 24-month follow-up, youths who received health information and skills intervention had lower intentions to smoke and less cigarette use than youths who received health information alone and youths who received no intervention. Conclusions about the effects of skills intervention are strengthened by the common preparation and random assignment of intervention leaders and by process measurement data. The objective of this study was to examine the effectiveness of a longitudinal community intervention on the reduction of tobacco sales to minors and subsequent effects on tobacco consumption by youths. The study was conducted in Monterey County, CA. Four rural communities were randomized into treatment and comparison arms of the study and middle and high school students in each of these communities completed surveys assessing knowledge, attitude, and behavior. The main outcome measures were retail tobacco sales to minors as measured through store visits (tobacco purchase surveys) and self-reported consumption of tobacco. Over a three-year period, a diverse array of community interventions were implemented in the intervention communities. These included community education, merchant education, and voluntary policy change. In the treatment communities, the proportion of stores selling tobacco to minors dropped from 75% at baseline to 0% at the final post-test. In the comparison communities, the proportions were 64% and 39%, respectively. Although the availability of tobacco through commercial outlets was reduced substantially in intervention communities, youths reported still being able to obtain tobacco from other sources. Predicted treatment effects on reported use of tobacco among youths were observed cross-sectionally and longitudinally for younger students (7th graders). The intervention did not impact tobacco use among older students (9th and 11th graders) although the trends were in the predicted direction for 9th graders. A significant intervention effect was found for sex--females in the intervention communities were less likely to use tobacco post-intervention than females in the comparison communities. Tobacco sales to minors can be reduced through a broad-based intervention. To prevent or reduce tobacco use by youths, however, multiple supply-and demand-focused strategies are needed. This randomized controlled trial evaluated the effectiveness of a multicomponent Health Promoting Schools (HPS) intervention program in improving self-reported smoking outcomes among a cohort of adolescents in 22 public secondary schools in the Hunter Region of New South Wales, Australia. Pre-test surveys were completed by students in the first 2 years of secondary school, with a 2-year post-test survey. Multivariate analyses examined intervention effect for the main outcome, post-test smoking behavior, controlling for pre-test smoking status, school and other confounders. The sample comprised the cohort of 1852 students who completed both surveys. The results demonstrated that the HPS program failed to improve smoking behavior over the 2 years (equal increase of 10% in both groups). The program was successful in improving smoking knowledge, but not attitudes, in intervention versus control group (P < 0.001). Independent predictors of post-test smoking included: pre-test smoking [odds ratio (OR) = 5.44; 95% confidence interval (CI) = 3.20-9.28], being female (OR = 0.55; CI = 0.35-0.87), having more close friends who smoked (OR = 1.42; CI = 1.33-1.52), peer group having no clear opinion about smoking (OR = 3.23; CI = 1.27-8.27), having more positive and less negative attitudes towards smoking, and being less involved in school activities. We discuss methodological issues in multicomponent community-based interventions, and highlight the strengths and limitations of this study. In a unique approach to utilizing an existing intervention, "opportunistic" and targeted school-based strategies were used to enroll 446 adults into a tailored preventive health program featuring a health screening and smoking-cessation intervention. Implemented through a public school district serving a multi-ethnic low-to-middle income urban community, subjects in this randomized trial were interviewed at enrollment and at three-, six-, and 12-month follow-up, and rescreened at 12 months, to assess changes in smoking-related knowledge, attitudes, and practices. Using conservative assumptions, self-reported ever-quit rates and continuous abstinence rates of 57.5% and 2.6%, respectively, were achieved across groups; point-prevalence abstinence rates were 13.2%, 12.9%, and 10.3% at three, six, and 12 months. The study examines issues relevant to smoking status and stages of change in this population. The role of the school in increasing access to needed health programming in underserved communities is explored. To assess the effect of an antismoking intervention focusing on adolescents in lower education. Students with lower education smoke more often and perceive more positive norms, and social pressure to smoke, than higher educated students. An intervention based on peer group pressure and social influence may therefore be useful to prevent smoking among these students.
                Group randomised controlled trial.
                26 Dutch schools that provided junior secondary education.
                1444 students in the intervention and 1118 students in the control group, all in the first grade, average age 13 years.
                Three lessons on knowledge, attitudes, and social influence, followed by a class agreement not to start or to stop smoking for five months and a class based competition.
                Comparison of smoking status before and immediately after and one year after the intervention, using multilevel analysis.
                In the intervention group, 9.6% of non-smokers started to smoke, in the control group 14.2%. This leads to an odds ratio of 0.61 (95% CI= 0.41 to 0.90) to uptake smoking in the intervention group compared with the control group. One year after the intervention, the effect was no longer significant.
                In the short-term, an intervention based on peer pressure decreases the proportion of adolescents with lower education who start smoking. Influencing social norms and peer pressure would therefore be a promising strategy in terms of preventing smoking among adolescents. The results also suggest that additional interventions in later years are needed to maintain the effect. The prevalence of adolescent smoking has been increasing rapidly in China. Theory-based smoking prevention programmes in schools may be an effective approach in preventing smoking among Chinese adolescents.
                A school-level cluster randomized controlled trial was conducted among 7th and 8th grade students (N = 2343) in four junior high schools in southern China during 2004-06. The theory-based, multi-level intervention was compared with the standard health curriculum. Outcome measures comprised changes in students' smoking-related knowledge, attitudes and behaviour.
                The mean knowledge scores from baseline to the 1- and 2-year follow-ups increased more in the intervention group than in the control group, whereas there was little change in attitude scores. At the 1-year follow-up (the total sample), the interventions reduced the probability of baseline experimental smokers' escalating to regular smoker [7.9 vs 18.3%; adjusted odds ratio (OR) 0.34, 95% confidence interval (CI) 0.12-0.97, P = 0.043], but did not reduce the probability of baseline non-smokers' initiating smoking (7.9 vs 10.6%; adjusted OR 0.86, 95% CI 0.54-1.38, P = 0.538). At the 2-year follow-up (only 7th grade students), similar proportions of baseline non-smokers initiated smoking in the intervention group and the control group (13.5 vs 13.1%), while a possibly lower proportion of baseline experimental smokers escalated to regular smoking in the intervention group than the control group (22.6 vs 40.0%; adjusted OR 0.43, 95% CI 0.12-1.57, P = 0.199).
                This multi-level intervention programme had a moderate effect on inhibiting the escalation from experimental to regular smoking among Chinese adolescents, but had little effect on the initiation of smoking. The programme improved adolescents' smoking-related knowledge, but did not change their attitudes towards smoking. To evaluate the effectiveness of a school-based smoking prevention and control intervention program among elementary school students.
                Through two phase cluster sampling, 566 pupils in grade 4 and grade 5 of two schools were assigned to intervention group and control group. One year comprehensive smoking intervention was conducted in the intervention group. The assessment was carried out through three questionnaires: pre- and post-intervention, 6-month after intervention.
                After one year intervention, pupils in the intervention group significantly improved their knowledge and attitudes related to tobacco use. The rate of attempting smoking decreased form 7.8% to 2.6% and the rate of passive smoking from 53.6% to 41.8%. The difference between the intervention and control groups was statistically significant. However, several index started to decline at 6-month follow up survey.
                The result demonstrated the effectiveness and feasibility of tobacco control in elementary school and the positive effect must be developed. Smoking reduction has been introduced as an alternative to smokers unable or unwilling to quit but has never been implemented in a population-based intervention.
                Two thousand four hundred eight daily smokers in all motivational stages were included in a randomised population-based intervention study, in Copenhagen, Denmark. Smokers, unwilling or unable to quit, were encouraged to reduce their tobacco consumption. Furthermore, smokers in the high-intensity intervention were offered participation in smoking reduction groups.
                Twenty-three percent of those who attended both baseline and 1 year visit reported reduction by at least 5 g and 8% reported a halving or more. Halving of tobacco consumption was achieved significantly more often than in the background population, OR = 2.6 (1.6-4.4), even when assuming that non-participants had not reduced, OR = 1.7 (1.0-2.8). Reduction of at least 5 g doubled the probability of increased motivation to quit and a halving increased it more than four times. The reductions were not validated. Less than 2% attended the smoking reduction groups.
                The smoking reduction intervention was significant in self-reported reduction of tobacco consumption and subsequently increased motivation to quit. This may open new perspectives, with reduction as a first step towards cessation, a possible supplement to smoking cessation strategies. Motivational interviewing techniques have been minimally researched as a function of a teenage smoking intervention. The present study examined the efficacy of a theory-based motivational tobacco intervention (MTI).
                A randomized two-group design was used to compare 6-month post-baseline quit and reduction rates among teenagers who received the MTI with those who received brief advice or care as usual. Participants were smokers aged 14 to 19 years (N = 75) who presented for treatment in a university-affiliated hospital emergency department (ED). Motivational interviewing techniques were used by trained providers to facilitate individual change; stage-based take-home materials also were provided.
                Similar to past clinic-based studies of motivational interviewing with teenage smokers, our study found negative results in terms of intervention efficacy for cessation. Six-month follow-up cessation rates were nonsignificant--two teenagers quit smoking. Among teenagers who were available at follow-up, a medium effect size (Cohen's h = .38) was found for reduction and a large effect size (Cohen's h = .69) was found for percentage reduction, although these results also were not statistically significant.
                Although the major findings of this study were not significant, the reductions in tobacco use suggest that motivational interviewing may be a clinically relevant counseling model for use in teenage smoking interventions. However, many questions remain, and the current literature lacks studies on trials with significant outcomes using motivational interviewing in smoking cessation. Additionally, more research is needed to examine the suitability of the ED for MTI-type interventions. This intervention was implemented to reduce the prevalence of cigarette smoking among women.
                We used community organization approaches to create coalitions and task forces to develop and implement a multicomponent intervention in 2 counties in Vermont and New Hampshire, with a special focus on providing support to help women quit smoking. Evaluation was by pre-intervention and post-intervention random-digit-dialed telephone surveys in the intervention counties and the 2 matched comparison counties.
                In the intervention counties, compared with the comparison counties, the odds of a woman being a smoker after 4 years of program activities were 0.88 (95% confidence interval = 0.78, 1.00) (P = .02, 1-tailed); women smokers' perceptions of community norms about women smoking were significantly more negative (P = .002, 1-tailed); and the quit rate in the past 5 years was significantly greater (25.4% vs 21.4%; P = .02, 1-tailed). Quit rates were significantly higher in the intervention counties among younger women (aged 18 to 44 years); among women with household annual incomes of $25,000 or less; and among heavier smokers (those who smoked 25 or more cigarettes daily).
                In these rural counties, community participation in planning and implementing interventions was accompanied by favorable changes in women's smoking behavior.
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.
