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 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. We aimed to determine the relative effectiveness of an education intervention and a threat-of-enforcement intervention in reducing sales of cigarettes to under-age youth by randomly allocating 300 retailers in a nonmetropolitan region of New South Wales to: a control group with no intervention; a minimal-intervention group, which received an educational letter; and a maximal-intervention group, which received a threat of enforcement followed by a visit from a public health officer. Retailers were checked for compliance at pretest and post-test, six months apart, by twelve 18-year-olds who were judged by independent raters to look younger. The retailers were surveyed by telephone at both times for knowledge, attitudes and self-reported sales practices. Neither intervention achieved significant improvements for the two key behavioural outcomes: requiring proof of age and display of a warning sign. Neither was there an intervention effect on knowledge about the law. The greatest improvement in the proportion of retailers who believed that the legal age should be 18 or over was in the minimal-intervention group, and both intervention groups were less likely than the control group at post-test to think that it was acceptable to sell to a person who was nearly 18. There was poor overall compliance with the revised legislation at pre-test. The finding of a pretest-to-post-test improvement but no differential intervention effect highlights the methodological difficulties of such research. The interventions may, however, have been partly successful in modifying the attitudes of retailers. Enforcing laws banning tobacco sales to minors is widely advocated as a way to reduce young people's access to tobacco and tobacco use. Whether this approach is successful is not known.
                In a two-year controlled study, we assessed sales of tobacco to minors and young people's access to and use of tobacco in six Massachusetts communities. Three communities (the intervention group) enforced tobacco-sales laws, whereas three matched communities (the control group) did not. To assess compliance with the law, minors working for the study investigators attempted to purchase tobacco from all retail vendors in each community every six months. Three annual anonymous surveys of a total of 22,021 students in grades 9 through 12 (response rate, 84 percent) measured access to tobacco and smoking behavior.
                At base line, 68 percent of 487 vendors sold tobacco to minors. Compliance with the law improved significantly faster in the intervention communities than in the controls (P<0.001). By the study's end, 82 percent of the merchants in the intervention communities complied with the law, as compared with 45 percent in the control communities (P<0.001). However, adolescents under 18 years old reported only a small drop in their ability to purchase tobacco and no decline in its use. Communities with and those without enforcement programs did not differ with respect to these outcomes.
                Enforcing tobacco-sales laws improved merchants' compliance and reduced illegal sales to minors but did not alter adolescents' perceived access to tobacco or their smoking. Test purchases of tobacco do not accurately reflect adolescents' self-reported access to tobacco, and reducing illegal sales to less than 20 percent of attempts -- the goal of a new federal law-- may not decrease young people's access to or use of tobacco. Enforcement of legislation restricting retail access to tobacco is increasingly relied on to reduce adolescent smoking rates. In 1996, health authorities in the Northern Sydney Health Area began monitoring tobacco retailer compliance (PROOF program) with staged purchase attempts by adolescents below the legal age (18 years). Repeat cross-sectional surveys before (1995) and after (2000) the introduction of PROOF monitored changes in adolescent smoking behaviour. Students aged 12 to 17 years from 11 Northern Sydney metropolitan public secondary schools were surveyed for self-reported smoking and tobacco purchasing behavior in 1995 (n = 5,206) and 2000 (n = 4,120). Between 1996 and 2000, 545 retailer compliance checks found 34% unlawfully sold cigarettes to minors and 28% of these repeated the offence. Nine prosecutions resulted. Modelling revealed a significant association between the intervention and never having smoked (adjusted OR = 1.16, 95% CI = 1.01-1.33) although there was no significant association with being a current smoker. The odds of being a smoker were greater for students from coeducational schools, with this effect being modified by gender. There was no reduction in adolescent smoking with active enforcement of tobacco access laws despite an apparent increase in students who reported never to have smoked. The current study explored the practicality of preventing underage retail cigarette sales and the relationship to cigarette supplies among adolescents.
                In Fort Morgan, Colorado, an isolated rural community with below-average socioeconomic status and a large Latino population, supervised teenaged employees repeatedly attempted to buy cigarettes from every store over a 9-month period in 2005. Repeated violations were penalized. Cigarette acquisition and exchange among community adolescents were assessed before and after intervention using a high school student survey.
                The measured violation rate declined from 47% in the first week to 3.4% during the final three months, and high school student reliance on retail cigarette purchases declined. Adolescent cigarette supplies declined by approximately 15%.
                Isolated rural communities can reduce adolescent cigarette supplies by conducting consistent enforcement against retail cigarette sales to minors. Previous research suggests that reducing these sales may help reduce adolescent smoking. The current study demonstrates that enforcement is practical and effective. This study evaluated an active enforcement program to increase retailers' compliance with the law prohibiting tobacco sales to minors.
                Tobacco sales to minors were monitored in 319 outlets in 6 pairs of communities in Erie County, New York. One community in each pair was randomly assigned to an enforcement intervention.
                Retailers' compliance with the law increased from 35% in 1994 to 73% in 1995. However, the change in compliance rates was roughly the same for stores in the enforcement and nonenforcement communities.
                Active compliance checking of retail outlets as a strategy to reduce illegal tobacco sales to minors may only be necessary insofar as it contributes to an increase in retailers' perception that the threat of enforcement is real. This study examined the changes in tobacco sales to minors after active enforcement of merchant compliance to the Synar regulation and the city of Philadelphia Youth Access to Tobacco Ordinance 732. Data for the present study were obtained through Tobacco-free Education and Action Coalition for Health (TEACH) Program in a 5-year, follow-up retail compliance check survey of 1649 stores in 14 cluster areas of Philadelphia, PA. Trend analysis was conducted ofthe sales of tobacco to minors by type of retail outlet, gender, and age of the buyer, and gender, age, and race of the store clerk, and whether restriction policy signs were posted. Analysis indicates that there was a reduction in tobacco sales to minors after implementation of enforcement; sales dropped from 85% in 1994 to 43% in 1998. There were less sales to minors when signs were posted. There were differences in sales if the buyer was asked his or her age and whether the minor was asked to show identification. In addition, the age of the buyer and the brand of cigarettes were associated with sales. Future research should focus on both commercial and social availability and provision of tobacco to minors. 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.

Interventions with retailers can lead to large decreases in the number of outlets selling tobacco to youths. However, few of the communities studied in this review achieved sustained levels of high compliance. This may explain why there is limited evidence for an effect of intervention on youth perception of ease of access to tobacco, and on smoking behaviour.
