Tobacco outlet density, retailer cigarette sales without ID checks and enforcement of underage tobacco laws: associations with youths' cigarette smoking and beliefs.

AIMS: To estimate the relationships of tobacco outlet density, cigarette sales without ID checks and local enforcement of underage tobacco laws with youth's life-time cigarette smoking, perceived availability of tobacco and perceived enforcement of underage tobacco laws and changes over time. DESIGN: The study involved: (a) three annual telephone surveys, (b) two annual purchase surveys in 2000 tobacco outlets and (c) interviews with key informants from local law enforcement agencies. Analyses were multi-level models (city, individual, time). SETTING: A sample of 50 mid-sized non-contiguous cities in California, USA. PARTICIPANTS: A total of 1478 youths (aged 13-16 at wave 1, 52.2% male); 1061 participated in all waves. MEASUREMENTS: Measures at the individual level included life-time cigarette smoking, perceived availability and perceived enforcement. City-level measures included tobacco outlet density, cigarette sales without ID checks and compliance checks. FINDINGS: Outlet density was associated positively with life-time smoking [OR = 1.12, P < 0.01]. An interaction between outlet density and wave (OR = 0.96, P < 0.05) suggested that higher density was associated more closely with life-time smoking at the earlier waves when respondents were younger. Greater density was associated positively with perceived availability (ß = 0.02, P < 0.05) and negatively with perceived enforcement (ß = -0.02, P < 0.01). Sales rate without checking IDs was related to greater perceived availability (ß = 0.01, P < 0.01) and less perceived enforcement (ß = -0.01, P < 0.01). Enforcement of underage tobacco laws was related positively to perceived enforcement (ß = 0.06, P < 0.05). CONCLUSIONS: Higher tobacco outlet density may contribute to life-time smoking among youths. Density, sales without ID checks and enforcement levels may influence beliefs about access to cigarettes and enforcement of underage tobacco sales laws.

Density and proximity of tobacco outlets to homes and schools: relations with youth cigarette smoking.

This study investigated the associations of youth cigarette smoking with tobacco outlet densities and proximity of tobacco outlets to youth homes and schools across different buffers in 45 midsized California communities. The sample comprised 832 youths who were surveyed about their smoking behaviors. Inclusion criteria included both home and school addresses within city boundaries. Observations in the 45 cities were conducted to document addresses of tobacco outlets. City- and buffer-level demographics were obtained and negative binomial regression analyses with cluster robust standard errors were conducted. All models were adjusted for youth gender, age, and race. Greater densities of tobacco outlets within both a 0.75 and 1-mile buffer of youth homes were associated with higher smoking frequency. Neither tobacco outlet densities around schools nor distance to the nearest tobacco outlet from home or school were associated with youths past-30-day smoking frequency. Lower population density and percent of African Americans in areas around homes and lower percent of unemployed in areas around schools were associated with greater smoking frequency. Results of this study suggest that restricting outlet density within at least 1-mile surrounding residential areas will help to reduce youth smoking.

Rating the effectiveness of local tobacco policies for reducing youth smoking.

Important questions remain regarding the effectiveness of local tobacco policies for preventing and reducing youth tobacco use and the relative importance of these policies. The aims of this paper are to: (1) compare policy effectiveness ratings provided by researchers and tobacco prevention specialists for individual local tobacco policies, and (2) develop and describe a systematic approach to score communities for locally-implemented tobacco policies. We reviewed municipal codes of 50 California communities to identify local tobacco regulations in five sub-domains. We then developed an instrument to rate the effectiveness of these policies and administered it to an expert panel of 40 tobacco researchers and specialists. We compared mean policy effectiveness ratings obtained from researchers and prevention specialists and used it to score the 50 communities. High inter-rater reliabilities obtained for each sub-domain indicated substantial agreement among the raters about relative policy effectiveness. Results showed that, although researchers and prevention specialists differed on the mean levels of policy ratings, their relative rank ordering of the effectiveness of policy sub-domains were very similar. While both researchers and prevention specialists viewed local outdoor clean air policies as least effective in preventing and reducing youth cigarette smoking, they rated tobacco sales policies and advertising and promotion as more effective than the other policies. Moreover, we found high correlations between community scores generated from researchers' and prevention specialists' ratings. This approach can be used to inform research on local policies and prevention efforts and help bridge the gap between research and practice.

Contextual and community factors associated with youth access to cigarettes through commercial sources.

OBJECTIVES: This study examines contextual and community-level characteristics associated with youth access to tobacco through commercial sources in 50 non-contiguous mid-sized California communities. METHODS: The study is based on data from access surveys conducted by four confederate buyers (two men and two women) in 997 tobacco outlets. City demographics, adult smoking prevalence, and measures of tobacco outlet density, local tobacco retailer licencing and cigarette tax were included. RESULTS: Multilevel regression analyses indicated that buyer's actual age, a male clerk and asking young buyers about their age were related to successful cigarette purchases. Buyer's actual age and minimum age signs increased the likelihood that clerks will request an identification (ID). At the community level, a higher percentage of minors, higher education, and a greater percentage of African-Americans were associated with an increased likelihood of a successful purchase. Lower percentage of minors, lower education, lower percentage of African-Americans, and having a local tobacco retailer licencing were associated with the retailer asking for an ID. Additionally, supermarkets charged significantly more for a pack of cigarettes than small markets, whereas, smoke/tobacco shops and drug stores/pharmacies charged less. Higher prices were associated with higher median household income and greater percentage of Hispanics. Findings about community characteristics, however, differed by cigarette brand. CONCLUSIONS: This study enhances our understanding of the associations between contextual and community characteristics and youth access to tobacco through commercial sources which can help policymakers to identify and target at-risk communities and outlets to decrease youth access to tobacco.

Community-level adult daily smoking prevalence moderates the association between adolescents' cigarette smoking and perceived smoking by friends.

Few studies have investigated the complex interactions among the individual- and community-level social risk factors that underlie adolescents' smoking behaviors. This study investigated whether community-level adult daily smoking prevalence is associated with adolescents' smoking and whether it moderates the associations between perceived friends' smoking approval and smoking behavior and adolescents' own smoking. Self-reported data from 1,190 youths (50.3% female; 13-18 years old) in 50 midsized Californian cities were obtained through telephone interviews. Community characteristics were obtained from 2010 GeoLytics data. Community adult daily smoking prevalence was ascertained from telephone interviews with 8,918 adults conducted in the same 50 cities. Multilevel analyses, controlling for individual and city characteristics, were used to predict adolescents' past 12-month smoking from perceived friends' smoking approval and smoking behavior and from community adult daily smoking prevalence. Results showed that perceived friends' smoking approval and behavior were associated positively with adolescents' smoking, as was the community-level prevalence of adult daily smoking. Furthermore, the association between perceived friends' smoking behavior and adolescents' own smoking was moderated by the prevalence of adult daily smokers in the community. Specifically, the association was stronger in cities with higher prevalence of adult smokers. These results suggest that adult community norms that are more supportive of smoking may enhance the influence of friends' smoking behavior. Therefore, interventions designed to prevent or reduce youths' smoking should also focus on reducing smoking by adults.

Evaluating environmental change strategies: challenges and solutions.

In this introductory article we define environmental change strategies (ECS), summarize the primary challenges associated with evaluating ECS, and provide an overview of the methods researchers have employed to begin to address these challenges. This special issue provides a range of examples, from researchers and practitioners in the field, of different approaches for addressing these challenges. These articles present new methods to understand and test how ECS are implemented and propose methods to evaluate their implementation. The content of the articles covers multiple public health issues, including substance abuse prevention, tobacco control, HIV prevention, and obesity prevention. This special issue is intended to build the evidence base for effective ECS, generate compelling discussion, critical analyses, and spur future research that will help improve the implementation and evaluation of ECS.

Simulation modeling of policies directed at youth sugar-sweetened beverage consumption.

Childhood obesity is a significant public health problem requiring innovative solutions. While recent reviews indicate that some policies show promise, there is a lack of information regarding which policies, and policy combinations, work best. Low-nutrition, energy-dense foods and beverages such as sugar-sweetened beverages (SSBs) have been identified as a major contributor to the problem. The purpose of this paper is to use simulation modeling to show how changes in three categories of SSB policies-school nutrition, school-based education, and taxes-impact SSB and other food consumption. The model shows that policies directed at SSBs, particularly tax hikes, could lead to substantial reductions in the number of calories consumed by youth. The estimates, however, are subject to a high degree of uncertainty. Estimates from school-based nutrition and school-based education policies, while also helping to reduce caloric intake, generally show smaller effects than tax policies and considerable variation around parameter estimates for individual and combined policies. We conclude with a discussion of the limits of the model, and suggest where additional information is needed. Limitations notwithstanding, simulation modeling is a promising methodology that can help advance our understanding of policy effects, thereby helping policymakers to better formulate effective policies to reduce obesity prevalence and the associated social harms.

Coalitional capacities and environmental strategies to prevent underage drinking.

Coalitions are the most common platform for implementing community-level environmental strategies (ES), such as media, policy, or enforcement for substance use prevention. The current study examines the associations between two types of coalition capacity (general and innovation-specific) and ES implementation efforts and outputs within 14 intervention communities over a three-year period. Efforts refer to the amount of energy exerted to implement an ES while outputs refer to the materials produced through these efforts. Quantitative measures of capacity were provided by coalition key informants and expert-raters. Additionally, Training and Technical Assistance (TTA) provided proactively to improve the implementation of ES was also examined. Greater general capacity, as rated by a coalition informant, was associated with more ES policy effort. Both expert-rated general and innovation-specific capacity, however, were associated with greater ES outputs. Study results also found that community coalitions that endorsed weaker mobilization, structure and task leadership, (measures of general capacity), utilized more TTA compared to those who perceived their coalition as having greater capacity. Moreover, communities that utilized more TTA resources reported a greater number of successful policy changes. The study supports the need to consider both general and innovation-specific capacity for ES implementation and offers promising preliminary findings regarding the role of TTA for improving coalitions' capacity to facilitate policy change.

The interactive systems framework applied to the strategic prevention framework: the Rhode Island experience.

The Interactive Systems Framework for Dissemination and Implementation (ISF) was introduced as a heuristic systems level model to help bridge the gap between research and practice (Wandersman et al., in Am J Commun Psychol 41:171-181, 2008). This model describes three interacting systems with distinct functions that (1) distill knowledge to develop innovations; (2) provide supportive training and technical assistance for dissemination to; (3) a prevention delivery system responsible for implementation in the field. The Strategic Prevention Framework (SPF) is a major prevention innovation launched by the Center for Substance Abuse Prevention (CSAP) of the Substance Abuse and Mental Health Services Administration (SAMHSA). The SPF offers a structured, sequential, data-driven approach that explicitly targets environmental conditions in the community and aims for change in substance use and problems at the population level. This paper describes how the ISF was applied to the challenges of implementing the SPF in 14 Rhode Island communities, with a focus on the development of a new Training and Technical Assistance Resources Center to support SPF efforts. More specifically, we (1) describe each of the three ISF interacting systems as they evolved in Rhode Island; (2) articulate the lines of communication between the three systems; and (3) examine selected evaluation data to understand relationships between training and technical assistance and SPF implementation and outcomes.

Local tobacco policy and tobacco outlet density: associations with youth smoking.

PURPOSE: This study investigates the associations between local tobacco policy, tobacco outlet density, and youth smoking. A primary focus is on whether local tobacco policy moderates the relation between outlet density and youth smoking. METHODS: In all, 1,491 youth (51.9% male, mean age = 14.7 years, standard deviation = 1.05) in 50 midsized California cities were surveyed through a computer-assisted telephone interview. Measures of local clean air policy and youth access policy were created based on a review of tobacco policies in these cities. Outlet density was calculated as the number of retail tobacco outlets per 10,000 persons, and city characteristics were obtained from 2000 U.S. Census data. RESULTS: Using multilevel regression analyses and controlling for city characteristics, tobacco outlet density was positively associated with youth smoking. No significant main effects were found for the two tobacco policy types on any of the smoking outcomes after controlling for interactions and covariates. However, statistically significant interactions were found between local clean air policy and tobacco outlet density for ever smoked and past 12-month cigarette smoking. Comparisons of simple slopes indicated that the positive associations between tobacco outlet density and youth smoking behaviors were stronger at the lowest level of local clean air policy compared with the moderate and high levels. CONCLUSIONS: Our results suggest that tobacco outlet density is related to youth smoking. In addition, local clean air policy may act as a moderator of relationship between tobacco outlet density and youth smoking, such that density is less important at moderate and high levels of this tobacco policy.

The impact of local U.S. tobacco policies on youth tobacco use: A critical review.

Tobacco use continues to be the leading preventable cause of premature death in the United States, killing over 430,000 people annually. Tobacco initiation and use among youth remains a significant public health concern. Despite declines in U.S. youth tobacco use in recent years, state and national survey results are still cause for alarm. Although traditional school-based curricular programs are the most common strategy to prevent or reduce youth tobacco use, their effectiveness may be limited because young people are immersed in a broader social context in which tobacco is readily available. Environmental strategies change this social context by focusing on policy, enforcement, and media. A compelling body of evidence suggests that interventions at the state and federal levels can, when implemented in combination, reduce youth tobacco use. The impact of policies implemented at the local levels is less well understood and effects of environmental strategies on smokeless tobacco consumption have been largely ignored. The purpose of this paper is to review the literature on environmental strategies implemented at the local level on youth use of both cigarettes and smokeless tobacco. We highlight results of the extant literature, hypothesize possible effects where research is lacking, and suggest where future studies might be warranted.

A review of the literature on policies directed at the youth consumption of sugar sweetened beverages.

Sugar sweetened beverages (SSB) constitute a large percentage of energy consumed by youth. This paper reviews the literature on school nutrition policies and price interventions directed at youth SSB consumption. In addition to considering the direct effect of policies on SSB consumption, we provide an overview of the literature on how SSB consumption affects total energy intake (TEI) and BMI, as well as on how TEI affects BMI. By considering each of these links, we attempted to gauge the effect of policies directed at SSB consumption, as well as highlight areas that merit future research. We found that school nutrition and price policies reduce SSB consumption and that reduced SSB consumption is associated with a reduction in energy intake that can influence BMI. Policies directed at SSB consumption can play an important role in reducing youth overweight and obesity.

Timevarying predictors of smoking cessation among individuals in treatment for alcohol abuse and dependence: findings from Project MATCH.

AIMS: Individuals in treatment for alcohol use disorders are more likely to die from cigarette use than from alcohol consumption. Advanced statistical methodologies that increase study power and clinical relevance have been advocated to examine the timevarying nature of substance use relapse and abstinence, including drinking and smoking. The purpose of this investigation was to examine timevarying factors that are associated with smoking cessation among smokers in the general population, including alcohol use, self-efficacy, and depression, to determine if they were also related to smoking cessation during and after treatment for alcohol use disorders. METHODS: Data were garnered from Project MATCH, a longitudinal prospective study of the efficacy of three behavioural treatments for alcohol use disorders. Timevarying covariate analyses were conducted to examine future smoking cessation. RESULTS: Results showed that greater self-efficacy regarding resisting temptations to drink and lower levels of depression were independently associated with increased likelihood of stopping smoking. In contrast, drinks per drinking day and confidence regarding not drinking did not demonstrate such associations. CONCLUSIONS: Clinical implications of these findings suggest that interventions to help alcoholics in recovery avoid temptations to drink, as well as decrease depression, may be warranted. By using advanced statistical techniques, these results can help clinicians and organizations working with smokers in treatment for alcohol use disorders to make informed decisions regarding how best to use limited resources.

Changes in cigarette consumption and drinking outcomes: findings from Project MATCH.

Individuals undergoing treatment for alcohol use disorders smoke at rates that exceed those reported in the general population, and most patients will continue to smoke after treatment completion. A growing body of research indicates that quitting smoking is associated with better alcoholism treatment outcomes. Studies that dichotomize participants into smokers and nonsmokers, however, may be overlooking the possibility that even decreases in cigarette consumption over time among continuing smokers may also be related to improved alcohol use outcomes. The purpose of this article was to examine the relationship between cigarette consumption and alcohol use outcomes using data from Project MATCH. Smokers were divided into three groups according to whether their cigarette consumption decreased, increased, or remained constant from baseline to the 15-month follow-up. Results showed that smokers whose cigarette consumption decreased were significantly less likely to relapse to alcohol use than those whose consumption increased or remained unchanged. These findings suggest that even reductions in tobacco use may be associated with better drinking outcomes in alcoholism treatment.

The adoption of tobacco dependence treatment by rehabilitation clinicians.

PURPOSE: Individuals with disabilities tend to smoke at rates that surpass those of the general population. The Pubic Health Service Guideline on the treatment of tobacco dependence suggests that all smokers be screened at every health care visit and counselled regarding how best to quit smoking. We review the literature on the adoption of tobacco dependence treatment by rehabilitation clinicians working with disabled individuals. Despite the deleterious health effects of smoking on individuals with disabilities, the limited data suggests that rehabilitation clinicians rarely encourage their clients who smoke to quit. METHOD: Studies were collected using various computerized databases from 1980 to the present. Because of the paucity of literature on tobacco dependence treatment utilization among rehabilitation clinicians, we also examine research on the use of tobacco dependence treatment by health care providers in the general population and in substance abuse treatment settings. RESULTS: Despite the efficacy of tobacco dependence treatment in smokers with disabilities, tobacco dependence treatment appears to be underutilized by rehabilitation clinicians. CONCLUSIONS: Interventions that have successfully increased adoption by the two other clinician groups should be utilized to increase tobacco dependence treatment provision by rehabilitation clinicians. Additional research is warranted to determine how to overcome obstacles to adoption.

Smoking cessation and alcohol consumption in individuals in treatment for alcohol use disorders.

Most individuals with alcohol use disorders are dependent on both alcohol and nicotine, and combined use of both substances is more damaging to health than use of either alone. Although research indicates that alcoholics can quit smoking, discrepant results have been reported regarding whether smoking cessation is associated with increased risk of alcohol relapse. The purpose of this paper was to examine the relationship between smoking cessation and alcohol consumption using data from Project MATCH. Of the 1,307 participants who smoked at any point during the study, 160 (12%) quit. Quitters consumed less alcohol than those who continued smoking. In addition, quitters demonstrated a significant reduction in alcohol consumption at the time of smoking cessation, which was sustained for six months post-cessation. These findings suggest that individuals in treatment for alcohol use disorders who are motivated to stop smoking can safely be encouraged to do so without jeopardizing their sobriety.

The effects of chronic nicotine and alcohol use on neurocognitive function.

Despite the extensive literatures on the independent effects of chronic nicotine and alcohol use on neurocognition, little is known about their combined impact. The purpose of this paper was to examine the effects of chronic nicotine and alcohol use on neurocognition in participants who took part in Project MATCH, a study of the efficacies of three behavioral treatments for adults diagnosed with alcohol abuse or dependence. Multiple regression and ANCOVA analyses were conducted to determine the relationship between lifetime weeks of tobacco use and years of alcohol use problems and neuropsychological test performance. Results showed that although years of chronic alcohol use was significantly inversely related to neuropsychological test scores, and chronic nicotine use showed an additive effect, substance use accounted for little variance in neuropsychological functioning. These findings suggest that some protective factors may have helped to attenuate the impact of chronic substance use on neurocognition. The importance of considering individual differences in such research is highlighted. Additional studies on the combined effects of chronic nicotine and alcohol use on neuropsychological function are warranted.

Smoking initiation among nonsmokers during and following treatment for alcohol use disorders.

Few studies have examined nonsmokers who enter treatment for alcohol use disorders to see what happens to their smoking status over time. Such individuals may be vulnerable to initiating tobacco use during or after treatment. Thus, the present study examined changes in the smoking status of the 387 baseline nonsmokers in Project MATCH during and following their treatment for alcohol use or dependence. Results showed that, of those who were nonsmokers at baseline, 15% initiated tobacco use during the 12- month followup period, most beginning during treatment. Smoking initiators' rates of tobacco consumption increased significantly between the 3- and 15-month followup assessments. These results suggest that smoking initiation during substance abuse treatment may be important to monitor and that efforts to help smoking initiators may be warranted.

Helping other alcoholics in alcoholics anonymous and drinking outcomes: findings from project MATCH.

OBJECTIVE: Although Alcoholics Anonymous (AA) is the largest mutual-help organization for alcoholics in the world, its specific mechanisms that mobilize and sustain behavior change are poorly understood. The purpose of this study is to examine prospectively the relationship between helping other alcoholics and relapse in the year following treatment for alcohol use disorders. METHOD: Data were derived from Project MATCH, a longitudinal prospective investigation of the efficacy of three behavioral treatments for alcohol abuse and dependence. Kaplan-Meier survival estimates were used to calculate probabilities of time to alcohol relapse. To identify the unique value of helping other alcoholics when controlling for the number of AA meetings attended, proportional hazards regressions were conducted to determine whether the likelihood of relapse was lower for those who were helping other alcoholics. RESULTS: There were no demographic differences that distinguished participants in regard to involvement in helping other alcoholics, with the exception of age; those who were helping other alcoholics were, on average, 3 years older than those who were not helping alcoholics. Those who were helping were significantly less likely to relapse in the year following treatment, independent of the number of AA meetings attended. CONCLUSIONS: These findings provide compelling evidence that recovering alcoholics who help other alcoholics maintain long-term sobriety following formal treatment are themselves better able to maintain their own sobriety. Clinicians who treat persons with substance abuse disorders should encourage their clients to help other recovering alcoholics to stay sober.
