Abstract
OBJECTIVE States and localities are formulating strategies to reduce the widespread retail availability of tobacco products. Evidence of associations between retailer density/proximity and tobacco use outcomes can help inform those strategies. We conducted a scoping review on tobacco retail availability and cigarette/e-cigarette use in adults and youth, and considered variations in spatial units, measures of retailer exposure and outcomes across studies. METHODS A systematic search for studies examining the association between retailer density/proximity and youth and adult cigarette/e-cigarette use was conducted across MEDLINE (PubMed), Web of Science and Google Scholar through 27 August 2020 with no restrictions. RESULTS Thirty-five studies were included in our qualitative synthesis. While there were differences in neighbourhood definitions (eg, egocentric vs administrative), there is evidence for a positive association between higher retailer density in egocentric neighbourhoods around homes and current smoking in adults and adolescents. Administrative unit measures in some studies showed associations with adult current smoking, and adolescent lifetime and current smoking. Studies on tobacco outlet proximity to homes obtained mixed results. Density/proximity of tobacco outlets around schools showed no or inverse association with adolescent smoking, but suggests higher susceptibility to smoking. Evidence of an association between e-cigarette retail availability and e-cigarette use is limited due to a small number of studies. CONCLUSION The current literature provides limited empirical evidence of the association between tobacco retailer availability and smoking or e-cigarette use. More research with uniform measures of environmental exposure to tobacco retailers is needed to allow for greater comparability between studies.

Abstract
Background: Smoking is one of the greatest challenges for public health. It is estimated that 7% - 25% of adolescents have experienced smoking in Iran. Objectives: The present study aimed to investigate the viewpoints of high school male students, their parents, and teachers about smoking by adolescents based on four components of the social marketing mix. Methods: A qualitative study with a phenomenological approach was conducted via 12 focus group sessions in Persian language. To this end, 82 participants (30 students, 28 parents, and 24 teachers) were selected based on purposive sampling method in 2015.The data were analyzed through directed content analysis. Results: All the three studied groups viewed “looking older” as the major cause of adolescent smoking, other factors included getting others’ attention, looking smart person, calmness, decreasing pain, and attractive packaging of cigarette. Some differences were observed between the viewpoints of students, parents, and teachers about the complications of cigarette. The students focused on the social consequences of smoking, but the parents and teachers were more worried about its long term physical side effects and addictive properties. Unlike parents, the teachers and students considered imitating from parents and famous people as the main socio-environmental factor of smoking. All three groups believed that people’s negative social image and negative attention towards smokers should be included in smoking prevention educational programs. However, some differences were reported between their ideas in other educational subjects. Conclusions: Evaluating factors related to tobacco use from three different perspectives can provide a more comprehensive view of these factors and show the reason for the failure of many efforts to prevent student tobacco use and develop a more effective program to promote health.

Abstract
INTRODUCTION While understanding factors that lead to successful adolescent smoking cessation outcomes is necessary, it is also prudent to determine factors and conditions that contribute to failure to quit smoking. The present study posits that adolescents' proximal environments, such as schools, may influence cessation treatment outcomes. METHODS Using aggregated and geographically-referenced data from multi-year school-based cessation trials with 14-19 year olds seeking cessation in 5 States of the USA, the present study developed and applied a tobacco-specific socio-spatial model inclusive of Hierarchical Linear Modeling. Specifically, this novel approach spatially joined individual data files (n=8855) with measures of school (n=807) and county socio-economic factors. Once linked multi-level analyses explored the extent to which cessation treatment failure was explained by the interplay of individual, school and county-level factors. Treatment was deemed as failing to meet its primary goals if participants continued to smoke cigarettes, measured 3-months post baseline. RESULTS Ten per cent of the variation in cessation treatment failure was attributable to school-level variables. Adolescent smokers were more likely to experience failure to quit in: a) school districts with large percentages of the population having less than high-school education, and b) schools with a higher ratio of students to teachers. The strength of the relationship between cessation self-efficacy and treatment success was further weakened among adolescents attending schools with higher percentages of students eligible for free or reduced lunch programs. CONCLUSIONS Findings implicate school-level socio-economic disadvantage as a significant factor inhibiting cessation, regardless of adolescent self-efficacy to quit smoking. Understanding the interplay of proximal school environments and individual-level factors may provide insights to educators, policy makers and practitioners into the complexities that inhibit or strengthen an adolescent's smoking cessation treatment experience.

Tobacco outlet density and tobacco knowledge, beliefs, purchasing behaviours and price among adolescents in Scotland. Soc Sci Med 2018; 206:1-13.

Abstract
Despite long-term falls in global adult smoking prevalence and over 50 years of tobacco control policies, adolescent smoking persists. Research suggests greater densities of tobacco retail outlets in residential neighbourhoods are associated with higher adolescent smoking rates. Policies to reduce retail outlets have therefore been identified by public health researchers as a potential 'new frontier' in tobacco control. Better understanding of the pathways linking density of tobacco retailers and smoking behaviour could support these policies. In this study we use path analysis to assess how outlet density in the home environment is related to adolescent tobacco knowledge, beliefs, retail purchases and price in Scotland. We assessed 22,049 13 and 15 year old respondents to the nationally representative cross-sectional 2010 Scottish School Adolescent Lifestyle and Substance Use Survey. Outlet density was based on Scottish Tobacco Retailers Register, 2012, data. A spatially-weighted Kernel Density Estimation measure of outlet density within 400 m of respondents' home postcode was grouped into tertiles. The analysis considered whether outlet density was associated with the number of cigarette brands adolescents could name, positive beliefs about smoking, whether smokers purchased cigarettes from shops themselves or through adult proxies and perceived cost of cigarettes. Models were stratified by adolescent smoking status. The path analyses indicated that outlet density was not associated with most outcomes, but small, significant direct effects on knowledge of cigarette brands among those who had never smoked were observed. With each increase in outlet density tertile the mean number of brands adolescents could name rose by 0.07 (mean = 1.60; SD = 1.18; range = 4). This suggests greater outlet densities may have affected adolescents' knowledge of cigarette brands but did not encourage positive attitudes to smoking, purchases from shops or lower cigarette prices. Exposure to tobacco outlets may influence adolescents' awareness of tobacco products, a potential pathway to smoking behaviour.

Abstract
Adolescent smoking prevention is an important issue in health care. This literature review describes the theoretical concept of ecological model for adolescent smoking and tobacco retailers and summarizes previous studies on the association between the density and proximity of tobacco retailers and adolescent smoking. We reviewed nine studies on tobacco retailer density and proximity in relation to adolescent smoking, published in peer-reviewed journals between 2004 and 2014. The tobacco retailer density and proximity were correlated with adolescent lifetime smoking, past 12-month smoking, past 30-day smoking, and susceptibility to smoking. School nurses or other school health professionals may need to include the density and proximity of tobacco retailer factors around schools in school-based tobacco-use prevention programs. Health policy makers may need to consider zoning or licensing restrictions of tobacco retailers around schools for adolescent smoking prevention.

Abstract
BACKGROUND Experience of tobacco use in early ages will increase probability of addiction to nicotine therefore, efficient tobacco control programs for teenagers are crucial. This study was conducted to recognize elements of successful integrated inside and outside of school based smoking prevention programs. METHODS MeSH terms and related keywords were used to search PubMed, Cochrane, Medline, EMBASE, ERIC, SID databases from inception to 29th October 2013. Trials with random and non-random designs, systematic reviews and cohort studies that assessed or reported application of integrated tobacco control programs were included. Quality of the retrieved publications was checked independently by the authors and any disagreement was resolved by consensus. RESULT Among the 745 identified publications, only 15 studies had the inclusion criteria with a considerable methodological heterogeneity. While, precise out-come of integrated out of school/school-based interventions were not percepti-ble but this study's findings implied that outside of school intervention could strengthen school-based tobacco prevention programs. No study was found to examine school-based interventions integrated with primary health care such as anti-tobacco consultations, high-risk students screening and their referral to special centers. CONCLUSION Integration of outside and inside of school-based programs may boost probability of obtaining favorable outcomes and success rate in practice.

Abstract
OBJECTIVE Internet addiction is one of the most common problems among adolescents and effective treatment is needed. This research aims to test the effectiveness and underlying mechanism of multi-family group therapy (MFGT) to reduce Internet addiction among adolescents. METHOD A total of 92 participants consisting of 46 adolescents with Internet addiction, aged 12-18years, and 46 their parents, aged 35-46years, were assigned to the experimental group (six-session MFGT intervention) or a waiting-list control. Structured questionnaires were administered at pre-intervention (T1), post-intervention (T2) and a three-month follow-up (T3). RESULTS There was a significant difference in the decline both in the average score and proportion of adolescents with Internet addiction in MFGT group at post-intervention (MT1=3.40, MT2=2.46, p<0.001; 100 versus 4.8%, p<0.001) maintained for three months (MT3=2.06, p<0.001; 100 versus 11.1%, p<0.001). Reports from both adolescents and parents were significantly better than those in the control group. Further explorations of the underlying mechanisms of effectiveness based on the changed values of measured variables showed that the improvement in adolescent Internet use was partially explained by the satisfaction of their psychological needs and improved parent-adolescent communication and closeness. CONCLUSIONS The six-session multi-family group therapy was effective in reducing Internet addiction behaviors among adolescents and could be implemented as part of routine primary care clinic services in similar populations. As family support system is critical in maintaining the intervention effect, fostering positive parent-adolescent interaction and addressing adolescents' psychological needs should be included in preventive programs for Internet addiction in the future.

Abstract
A growing body of research has examined whether racial/ethnic residential segregation contributes to health disparities, but recent findings in the literature, particularly with respect to cardiovascular disease (CVD) risk, have not been summarized. This review provides an overview of findings from studies of racial/ethnic residential segregation of non-Hispanic blacks and Hispanics with CVD risk published between January 2011 and July 2014. The majority of studies of black segregation showed higher segregation was related to higher CVD risk, although relationships were less clear for certain outcomes. Relationships among Hispanics were more mixed and appeared to vary widely by factors such as gender, country of origin, racial identity, and acculturation. Implications for research on racial/ethnic disparities in CVD and lingering gaps in the literature are discussed as well.

Abstract
This study examines lowest cigarette prices in all tobacco retail outlets in Washington D.C. (n=750) in relation to the type and number of high schools nearby, controlling for confounders. The lowest overall and Newport menthol prices were significantly lower at outlets near public non-charter and charter schools compared with outlets near private schools. Given higher smoking prevalence and more price-sensitive youth subgroups in U.S. public schools, exposure to low prices may contribute to tobacco-related health disparities in minority and low-income populations. Tobacco taxes combined with policies to minimize the increasing use of price as a marketing tool are critical.

Abstract
Although sociologists, demographers, and others have thoroughly studied contextual and life course influences on tobacco and alcohol use in adolescence and young adulthood, far less attention has been paid to the determinants of tobacco and alcohol co-use. This is important to remedy because co-use has a nonadditive effect on long-term health. In this article, we use nationally representative, longitudinal data from adolescents and young adults to examine patterns of joint tobacco and alcohol use behaviors across the life course. Importantly, we describe how these trajectories are linked to respondents' high school's joint profile of tobacco and alcohol use, measured two ways: as the proportion of tobacco and alcohol co-users, and as the "excess proportion" above that expected based on the marginal probabilities of smoking and drinking in that school. Joint tobacco and alcohol use is associated with both measures, emphasizing the "long arm" of adolescent contexts. Furthermore, we extend previous research to assess whether there is a gene-environment interaction between this school-level measure, 5HTTLPR, and tobacco and alcohol co-use, as suggested by recent work analyzing drinking and smoking separately. We find evidence of such a pattern but conclude that it is likely to be due to population stratification or other forms of confounding.
