The European Smoking Prevention Framework Approach (ESFA) study in six countries tested the effects of a comprehensive smoking prevention approach after 24 (T3; N = 10,751) and 30 months (T4; N = 9,282). The programme targeted four levels, i.e. adolescents in schools, school policies, parents and the community. In Portugal, 12.4% of the T1 non-smokers in the control group had started smoking at T4 compared to 7.9% of the experimental group. Smoking onset in the experimental group was thus 36% lower. In Finland, 32.4% of the T1 non-smokers started smoking compared to 27.6% of the experimental group, implying a 15% lower onset in the experimental group. In Spain, 33.0% of the T1 non-smokers in the control group had started smoking, compared to 29.1% of the experimental group, implying a 12% lower onset. In The Netherlands, the ESFA programme was effective for non-native adolescents with 11.4% new weekly smokers compared to 19.9% in the control group. An opposite effect was found in native Dutch adolescents with 19.0% new weekly smokers in the comparison group compared to 24.0% new smokers in the experimental group. Future programmes should use more standardized ways to assess process evaluations and should assess which elements are responsible for behavioral effects. This paper presents the 1-year outcomes evaluation of Project Towards No Drug Abuse (Project TND), a large-scale indicated drug abuse prevention program in southern California applied to continuation high school youth, who are at high risk for drug abuse.
                The efficacy of nine-lesson health motivation--social skills--decision-making curriculum was evaluated in a three-condition experimental design. Twenty-one schools were randomly assigned by block to one of three conditions--standard care (control), classroom program, and classroom program plus a semester-long school-as-community component. A pretest was followed by a 3-week-long drug abuse prevention program and then a posttest at 14 continuation high schools. The 7 standard care schools received only the pretest followed by the posttest (same time duration). Subjects were followed up 1 year later.
                Changes in use of cigarettes, alcohol, marijuana, and hard drugs were assessed in a pretest-1-year follow-up time interval. The follow-up rate was 67% (analysis n = 1,074). Indicated preventive effects were found on alcohol and hard drug use. No differences were found across the two program conditions.
                Project TND is the first program to demonstrate 1-year self-reported behavioral effects on alcohol use and hard drug use among older, high-risk youth by using a school-based, limited-session model. This study developed and tested skills- and community-based approaches to prevent substance abuse among Native American youth. After completing pretest measurements, 1,396 third- through fifth-grade Native American students from 27 elementary schools in five states were divided randomly by school into two intervention arms and one control arm. Following intervention delivery, youths in all arms completed posttest measurements and three annual follow-up measurements. Youths in schools assigned to the intervention arms learned cognitive and behavioral skills for substance abuse prevention. One intervention arm additionally engaged local community residents in efforts to prevent substance use among Native American youth. Outcome assessment batteries measured youths' reported use of smoked and smokeless tobacco, alcohol, and marijuana. Over the course of the 3.5-year study, increased rates of tobacco, alcohol, and marijuana use were reported by youths across the three arms of the study. Though cigarette use was unaffected by intervention, follow up rates of smokeless tobacco, alcohol, and marijuana use were lower for youths who received skills intervention than for youths in the control arm. Community intervention components appeared to exert no added beneficial influence on youths' substance use, beyond the impact of skills intervention components alone. Finally, gender differences were apparent across substances, measurements, and study arms, with girls smoking more cigarettes and boys using more smokeless tobacco, alcohol, and marijuana. The 1985 Minnesota Legislature established guidelines for school-based tobacco-use prevention programming and provided financial incentives to school districts to encourage them to adopt a broad range of preventive measures. The Minnesota-Wisconsin Adolescent Tobacco-Use Research Project was funded by the National Cancer Institute in 1986 to evaluate the Minnesota initiative through two parallel studies.
                The Four Group Comparison Study was a prospective study of 48 school "units" which were randomly assigned to one of four conditions in 1987. Baseline observations were taken in the sixth grade in 1987, interventions were delivered in the seventh grade, and follow-up observations were taken in the seventh, eighth, and ninth grades. The Four Group Comparison Study was designed to evaluate the three middle-school interventions that were most widely adopted by Minnesota school districts as a result of the 1985 legislation. The Two State Comparison Study was a serial cross-sectional study of representative districts in Minnesota and Wisconsin. Annual surveys of ninth graders were conducted from 1986-1990. The Two State Comparison Study was designed to determine whether tobacco-use patterns changed in Minnesota relative to Wisconsin following the Minnesota legislation.
                The prospective study indicated that none of the interventions was more effective in reducing adolescent tobacco use compared with a randomized control group. The serial cross-sectional study revealed that there was a modest net decline in Minnesota relative to Wisconsin from 1986 to 1990, but that it was within the range of chance variation.
                Taken together, these results indicate that this legislative initiative was insufficient to reduce adolescent tobacco use statewide during the 5-year study period. Together with results from other recent studies, they suggest that even more intensive efforts may be required to effect widespread reductions in adolescent tobacco use. To test whether the Communities That Care (CTC) prevention system reduces adolescent alcohol, tobacco, and other drug use and delinquent behavior communitywide.
                The Community Youth Development Study is the first randomized trial of CTC.
                In 2003, 24 small towns in 7 states, matched within state, were randomly assigned to control or CTC conditions.
                A panel of 4407 fifth-grade students was surveyed annually through eighth grade. Intervention A coalition of community stakeholders received training and technical assistance to install the CTC prevention system. They used epidemiological data to identify elevated risk factors and depressed protective factors in the community, and chose and implemented tested programs to address their community's specific profile from a menu of effective programs for families, schools, and youths aged 10 to 14 years.
                Incidence and prevalence of alcohol, tobacco, and other drug use and delinquent behavior by spring of grade 8.
                The incidences of alcohol, cigarette and smokeless tobacco initiation, and delinquent behavior were significantly lower in CTC than in control communities for students in grades 5 through 8. In grade 8, the prevalences of alcohol and smokeless tobacco use in the last 30 days, binge drinking in the last 2 weeks, and the number of different delinquent behaviors committed in the last year were significantly lower for students in CTC communities.
                Using the CTC system to reduce health-risking behaviors in adolescents can significantly reduce these behaviors communitywide. 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. 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. Evaluate a community-based tobacco/alcohol use-prevention program group compared with an attention-control condition (first aid/home safety) group.
                A total of 660 adolescents and 1 adult caregiver for each were recruited through the Migrant Education Program to participate in an 8-week intervention. Random assignment to the two groups occurred in 22 schools. Seventy 8-week intervention groups (37 tobacco/alcohol and 33 attention-control) were conducted. Assessments occurred at baseline, immediate post-intervention, and 1- and 2-year follow-ups. Susceptibility to smoking and alcohol as well as smoking and drinking over the past 30 days were the primary outcomes of interest.
                Following intervention, no between-group differences in smoking or drinking were significant. Thirty-day smoking started and remained at very low levels, with the highest group prevalence at any measurement period being 4.7% and the lowest 2.5%. Those considered susceptible to smoking dropped by nearly 40% in the attention-control group and by 50% in the intervention group from baseline to the final follow-up. (The overall reduction from post-test to final follow-up was statistically significant.) Less-acculturated children were less likely to report drinking in the past 30 days.
                The current intervention was not demonstrated to be effective in preventing cigarette or alcohol consumption. This perhaps is due to very low baseline levels of smoking and drinking in the migrant youth participants. Tested the effectiveness of a youth drug prevention program in a community setting. Boys & Girls Clubs of America's Stay SMART program, adapted from a school-based personal and social competence drug prevention program, was offered, with and without a 2-year booster program, to 13-year-old members of Boys & Girls Clubs. Over 27 months, (a) 5 Boys & Girls Clubs offered the Stay SMART program, (b) 5 Boys & Girls Clubs offered the Stay SMART program with the booster programs, and (c) 4 Boys & Girls Clubs served as a control group. The Stay SMART program alone and the Stay SMART program with the booster programs showed effects for marijuana-related behavior, cigarette-related behavior, alcohol-related behavior, overall drug-related behavior, and knowledge concerning drug use. The Stay SMART program with the booster programs produced additional effects for alcohol attitudes and marijuana attitudes after each year of booster programs. Results suggest that a school-based personal and social competence program can be adapted effectively to a community setting and that booster programs might enhance program effects. Implications for alternative community models of prevention are discussed. To evaluate the effect of the middle and junior high school Drug Abuse Resistance Education (D.A.R.E.) and D.A.R.E. Plus programs on drug use and violence.
                Randomized controlled trial of 24 schools, with 3 conditions: D.A.R.E. only, D.A.R.E. Plus, and delayed program control.
                Schools and neighborhoods, primarily in Minneapolis-St Paul.
                All seventh-grade students in 24 schools in the academic year 1999-2000 (N = 6237 at baseline, 67.3% were white, and there was 84.0% retention at final follow-up).
                The middle and junior high school D.A.R.E. curriculum in the 16 schools that received D.A.R.E. only and D.A.R.E. Plus. In the 8 schoolts that received D.A.R.E. Plus, additional components included a peer-led parental involvement classroom program called "On the VERGE," youth-led extracurricular activities, community adult action teams, and postcard mailings to parents. The interventions were implemented during 2 school years, when the cohort was in the seventh and eighth grades.
                Self-reported tobacco, alcohol, and marijuana use; multidrug use; violence; and victimization, assessed at the beginning and end of seventh grade and at the end of eighth grade. Growth curve analytic methods were used to assess changes over time by condition.
                There were no significant differences between D.A.R.E. only and the controls; significant differences among boys between D.A.R.E. Plus and controls for tobacco, alcohol, and multidrug use and victimization; significant differences among boys between D.A.R.E. Plus and D.A.R.E. only in tobacco use and violence; and no significant behavioral differences among girls.
                D.A.R.E. Plus significantly enhanced the effectiveness of the D.A.R.E. curriculum among boys and was more effective than the delayed program controls, underscoring the potential for multiyear, multicomponent prevention programs and demonstrating sex differences in response to intervention programs. We assessed the effectiveness of a 2-year multicomponent, school-based intervention designed to reduce tobacco use rates among adolescents in an urban area of India.
                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. A community health promotion project called Action Heart was undertaken in two electoral wards in Rotherham to try to change lifestyles of people. Schools were included within the project. Coronary heart disease lifestyle risk factors were measured at baseline and after a three year period in the intervention area and a similar control area. Lifestyle factors in schoolchildren were measured separately from adults using a different instrument. The post intervention survey of adults and economic evaluation demonstrated that Action Heart had achieved cost-effective estimated health gains. In the schoolchildren however, a mixture of positive and negative risk factor changes in both areas was demonstrated. Significant changes in lifestyle risk factors in schoolchildren were not elicited using this approach. The possible reasons for the lack of impact on lifestyle risk factors in schoolchildren are examined and the implications for further work explored. The entire early adolescent population of the 15 communities that constitute the Kansas City (Kansas and Missouri) metropolitan area has participated in a community-based program for prevention of drug abuse since September 1984. The Kansas City area is the first of two major metropolitan sites being evaluated in the Midwestern Prevention Project, a longitudinal trial for primary prevention of cigarette, alcohol, and marijuana use in adolescents. The project includes mass media programming, a school-based educational program for youths, parent education and organization, community organization, and health policy components that are introduced sequentially into communities during a 6-year period. Effects of the program are determined through annual assessments of adolescent drug use in schools that are assigned to immediate intervention or delayed intervention control conditions. In the first 2 years of the project, 22,500 sixth- and seventh-grade adolescents received the school-based educational program component, with parental involvement in homework and mass media coverage. Analyses of 42 schools indicate that the prevalence rates of use for all three drugs are significantly lower at 1-year follow-up in the intervention condition relative to the delayed intervention condition, with or without controlling for race, grade, socioeconomic status, and urbanicity (17% vs 24% for cigarette smoking, 11% vs 16% for alcohol use, and 7% vs 10% for marijuana use in the last month), and the net increase in drug use prevalence among intervention schools is half that of delayed intervention schools. 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. This study evaluated the long-term effects of a school- and community-based smoking prevention program in Finland.
                Four intervention schools from North Karelia and two control schools from another province were chosen for the evaluation. Students who received the intervention were taught to resist social pressures to smoke. The program began in 1978 with seventh-grade students and ran through 1980, with a 15-year follow-up. In North Karelia, a community-based smoking cessation program for adults was also carried out.
                Mean lifetime cigarette consumption was 22% lower among program subjects than among control subjects. Smoking and prevalence were lower up to the age of 21.
                Long-term smoking prevention effects can be achieved if a school-based program using a social influence model is combined with community and mass media interventions. 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. In a randomized controlled trial, we evaluated the effect on tobacco use onset among middle school students of Family Communications (FC) activities designed to mobilize parental influences against tobacco use and Youth Anti-tobacco Activities (YAT) designed to market anti-tobacco norms to adolescents. We conducted a simple, two-condition experimental design in which 40 middle schools, with a prevalence of tobacco use at or above the Oregon median, received, by random assignment, either the intervention or no intervention. State, county, and local prevention coordinators around Oregon served as liaisons to schools. To generate interest, staff made presentations to these groups and distributed marketing packets at several conferences. Dependent variables were indices of smoking prevalence and use of smokeless tobacco (ST) in the prior month. Additionally, we created an intervention manual so that other communities could replicate this study. The findings suggest that efforts to influence parents to discourage their children's tobacco use and efforts to market an anti-tobacco perspective to teens are effective in preventing smoking. The impact of YAT is consistent with experimental and nonexperimental evaluations of media campaigns to influence young people not to smoke. While clean indoor air (CIA) policies are intended to reduce exposure to second-hand smoke in the workplace, restrictions in public workplaces have the potential to discourage youth smoking. There is growing evidence from cross-sectional and ecological studies, but limited evidence from longitudinal studies that this is so.
                To evaluate the association between local CIA policies and smoking behaviours among Minnesota youth over time. Design, setting and
                A cohort of 4233 Minnesota youths, ages 11 to 16 at baseline, was interviewed via telephone for 6 years (2000-2006). Individual, family and community level variables were collected from participants every 6 months. A generalised estimating equation (GEE) logistic regression was used to assess the relationship between CIA policies and past-month smoking in youth over time. The analysis was controlled for potential confounders at individual and community levels.
                There was not significant association between CIA policies and youth smoking behaviours in the multivariate analyses. At the individual level, parental smoking significantly increased the odds of smoking nearly 40% and close friend smoking increased the odds of past-month smoking by nearly 100% for each close friend. Banning smoking in the home was significantly associated with a 12% reduction in the odds of past-month smoking.
                After accounting for other community and individual level factors known to be associated with youth smoking, there was no significant association between CIA policies and past-month smoking for youth over time. To prevent early adolescent health risk behaviors and to maintain or improve safety behaviors, we compared the effects of 2 interventions, delivered through pediatric primary care practices. The interventions, based on an office systems' approach, sought to prevent early drinking and smoking or to influence bicycle helmet use, gun storage, and seatbelt safety for children who were followed from fifth/sixth grades through eighth/ninth grades.
                Settings and Participants. Twelve pediatric practices in New England were paired according to practice size and assigned randomly within pairs to deliver the multicomponent interventions, which built on pediatric primary care clinicians performing as counselors and role models during health supervision visits and other office encounters.
                One intervention arm focused on alcohol and tobacco use. The other intervention arm focused on gun safety, bicycle helmet, and seatbelt use. Office systems provided infrastructure that supported the clinician's role. Clinician messages encouraged family communication and rule setting about the issues of the middle school years. The intervention was initiated during a health supervision visit and continued for 36 months. Both child and parent received quarterly newsletters to reinforce the clinician messages.
                The primary outcomes were ever drinking alcohol, ever smoking, ever using smokeless tobacco, using a bicycle helmet in the previous year, using a seatbelt in the previous 30 days, and guns in the child's home in locked storage.
                The pediatric practices recruited 85% (N = 3525) of the practices' fifth/sixth grade children and their responding parents. We obtained 36 months' follow-up data on 2183 child-parent pairs. Chart audit verified that the intervention was implemented. Additional data from interviews and surveys showed that parents, children, and pediatric clinicians found the intervention useful. Despite this, comparisons between the 2 study arms show no significant intervention effects in the prevention of alcohol and tobacco use or gun storage or seatbelt safety. There was a negative effect in the alcohol arm. Only bicycle helmet use showed a positive outcome.
                With rigorous evaluation, 2 office interventions failed to produce desired outcomes. Coordinated multiple settings for prevention interventions are probably necessary.
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.
