Kim J, Lee S. Factors associated with Korean adolescent's e-cigarette use by the severity level of generalized anxiety disorder (GAD-7). J Affect Disord 2023; 340:129-138. [PMID: 37544484 DOI: 10.1016/j.jad.2023.08.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2023] [Revised: 08/02/2023] [Accepted: 08/03/2023] [Indexed: 08/08/2023]
Abstract
BACKGROUND The use of e-cigarette among Korean adolescents is spreading with alarming rapidity, but it has not been studied along with the severity level of GAD-7. This study aims to identify adolescents' e-cigarette use and its associated factors among four different anxiety groups using the problem behavioral theory (PBT). METHODS A cross-sectional secondary dataset was retrieved from the 2020 Korea Youth Risk Behavior Survey. Of the total sample of 54,948, four anxiety groups were formed: minimal (score 0-4; n = 36,711), mild (score 5-9; n = 12,138), moderate (score 10-14; n = 4143), and severe (score above 15; n = 1965). A total of 11 variables were selected based on the PBT domains. Descriptive analysis, Chi-square, ANOVA, univariate analysis, and multiple linear regression analysis were performed. RESULTS E-cigarette use was the highest in the order of severe, mild, moderate, and minimal. While cigarette use was associated with vaping in all anxiety groups, adolescents with minimal or mild anxiety levels were more likely to be influenced by tobacco accessibility and other behavior system factors such as sexual intercourse, alcohol use, and smartphone addiction. Meanwhile, secondhand smoke exposure in public areas was only associated with those with severe anxiety levels, and secondhand smoke exposure at school was a significant factor in all anxiety groups except for those with moderate anxiety levels. LIMITATION Due to the nature of cross-sectional dataset, the study could not draw causal links between vaping and other identified factors, include all the necessary PBT components. CONCLUSION These findings underscore the need to consider different levels of anxiety when addressing the problems related to vaping among Korean adolescents.

Association between the extension of smoke-free legislation and incident acute myocardial infarctions in Singapore from 2010 to 2019: an interrupted time-series analysis. BMJ Glob Health 2023; 8:e012339. [PMID: 37816537 PMCID: PMC10565237 DOI: 10.1136/bmjgh-2023-012339] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2023] [Accepted: 07/30/2023] [Indexed: 10/12/2023] Open
Abstract
BACKGROUND We examined the association between smoke-free laws implemented in the outdoors and the common areas of residential apartment blocks and reported acute myocardial infarctions (AMI) in Singapore. METHODS We used an interrupted time-series design and seasonal autoregressive integrated moving average models to examine the effect of the smoke-free law extensions in 2013 (common areas of residential blocks, covered pedestrian linkways, overhead bridges and within 5 m of bus stops), 2016 (parks) and 2017 (educational institutions, buses and taxis) on the monthly incidence rate of AMIs per 1 000 000 population. RESULTS We included 133 868 AMI reports from January 2010 to December 2019. Post-2013, there was a decrease in the AMI incidence trend (β=-0.6 per month, 95%CI -1.0 to -0.29) and 2097 (95% CI 2094 to 2100) more AMIs may have occurred without the extension. There was a significant step-decline in male AMIs and a non-significant step-increase in female AMIs post-2013. Those 65 years and older experienced a greater decline to the postlegislation 2013 trend (β=-5.9, 95% CI -8.7 to -3.1) compared with those younger (β=-0.4, 95% CI -0.6 to -0.2), while an estimated 19 591 (15 711 to 23472) additional AMI cases in those 65 years and above may have occurred without the extension. We found a step-increase in monthly AMI incidence post-2016 (β=14.2, 95%CI 3.3 to 25.0). CONCLUSION The 2013 smoke-free law extension to residential estates and other outdoor areas were associated with a decline in AMIs and those above the age of 65 years and men appeared to be major beneficiaries. Additional epidemiological evidence is required to support the expanded smoke-free legislation to parks, educational institutions, buses and taxis.

JAMA Netw Open 2023; 6:e2322341. [PMID: 37418258 PMCID: PMC10329215 DOI: 10.1001/jamanetworkopen.2023.22341] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 05/22/2023] [Indexed: 07/08/2023] Open
Abstract
Importance Smoking causes considerable noncommunicable diseases, perinatal morbidity, and mortality. Objective To investigate the associations of population-level tobacco-control policies with health outcomes. Data Sources PubMed, EMBASE, Web of Science, Cumulated Index to Nursing and Allied Health Literature, and EconLit were searched from inception to March 2021 (updated on 1 March 2022). References were manually searched. Study Selection Studies reporting on associations of population-level tobacco control policies with health-related outcomes were included. Data were analyzed from May to July 2022. Data Extraction and Synthesis Data were extracted by 1 investigator and cross-checked by a second investigator. Analyses were conducted using the Preferred Reporting Items for Systematic Reviews and Meta-analyses reporting guideline. Main Outcomes and Measures The primary outcomes were respiratory system disease (RSD), cardiovascular disease (CVD), cancer, mortality, hospitalization, and health care utilization. The secondary outcomes were adverse birth outcomes, such as low birth weight and preterm birth. Random-effects meta-analysis was used to estimate pooled odds ratios (ORs) and 95% CIs. Results Of 4952 records identified, 144 population-level studies were included in the final analysis; 126 studies (87.5%) were of high or moderate quality. The most frequently reported policies were smoke-free legislation (126 studies), followed by tax or price increases (14 studies), multicomponent tobacco control programs (12 studies), and a minimum cigarette purchase age law (1 study). Smoke-free legislation was associated with decreased risk of all CVD events (OR, 0.90; 95% CI, 0.86-0.94), RSD events (OR, 0.83; 95% CI, 0.72-0.96), hospitalization due to CVD or RSD (OR, 0.91; 95% CI, 0.87-0.95), and adverse birth outcomes (OR, 0.94; 95% CI, 0.92-0.96). These associations persisted in all sensitivity and subgroup analyses, except for the country income category, for which a significant reduction was only observed in high-income countries. In meta-analysis, there was no clear association of tax or price increases with adverse health outcomes. However, for the narrative synthesis, all 8 studies reported statistically significant associations between tax increases and decreases in adverse health events. Conclusions and Relevance In this systematic review and meta-analysis, smoke-free legislation was associated with significant reductions in morbidity and mortality related to CVD, RSD, and perinatal outcomes. These findings support the need to accelerate the implementation of smoke-free laws to protect populations against smoking-related harm.

Abstract
OBJECTIVES Given the growing interest worldwide in applying public policies to improve human health, we undertook a systematic review of studies investigating whether public policies targeting unhealthy products could reduce cardiovascular diseases. STUDY DESIGN This study was a systematic review of the literature. METHODS We searched research studies published in 2000-2020 from major databases, including MEDLINE and Embase. We followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and narratively synthesized the studies based on vote counting and direction of the intervention effect. RESULTS Ninety-eight studies, mostly from high-income countries, met the inclusion criteria. Most studies were on public policies targeting sugar-sweetened beverages and tobacco, followed by alcohol, sugar, salt, and junk foods. Overall, many reported that several fiscal, regulatory, and educational policies generated beneficial effects of reducing the diseases. Those studies that reported no or limited effects highlighted several sociodemographic and health risk characteristics and design and implementation aspects of the policy interventions as factors limiting the policy effects; most of these are modifiable with appropriate policy interventions. For instance, low magnitude of tax, substitution with other unhealthy products, firms' competitive response strategies, pre-existence of smoking bans, incremental enactment of smoking regulations, degree of enforcement, and various sociocultural factors minimized the effects of the policies. CONCLUSION The literature supports a growing consensus on the beneficial effects of public policy for improving human health. The design and implementation of public policies must address various impeding factors and incorporate appropriate remedial measures. Further research is needed from low- and middle-income countries and on whether and how multiple policy instruments work in tandem.

Abstract
OBJECTIVES The aim of this study is to determine the factors that influence individuals' exposure to tobacco smoke in Turkey according to their education level. DESIGN Secondary data analysis. PARTICIPANTS Altogether, 17 084 individuals aged 15 and over were included in this study. SETTINGS Data set of the Turkey Health Survey in 2019. METHODS Binary logistic regression analysis was used to determine the factors associated with individuals' exposure to tobacco smoke. PRIMARY AND SECONDARY OUTCOME MEASURES The variables age, gender, marital status, general health status, employment status, receipt of psychosocial support and tobacco use were found to be correlated with exposure to tobacco smoke. RESULTS The study determined that individuals who are illiterate/unschooled were exposed to tobacco smoke at a rate of 32.61%, primary school graduates at a rate of 34.32%, primary education graduates at a rate of 41.75%, high school graduates at a rate of 41.04% and university graduates at a rate of 40.34%. CONCLUSION As a result of the study, it is emphasised that men, young individuals, individuals with moderate and very good general health status, those who use tobacco, those who are unemployed and those who receive psychosocial support should be targeted. In addition, appropriate strategies for reducing secondhand smoke (SHS) exposure should be developed, taking into account public health strategies for increasing awareness of the adverse health effects of SHS exposure and the determinants of tobacco exposure according to the study.

Exposure to secondhand smoke in hospitality settings in Ghana: Evidence of changes since implementation of smoke-free legislation. Tob Induc Dis 2020; 18:44. [PMID: 32477039 PMCID: PMC7252429 DOI: 10.18332/tid/120934] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2020] [Revised: 04/08/2020] [Accepted: 04/21/2020] [Indexed: 11/24/2022] Open
Abstract
INTRODUCTION Ghana has a partial smoking ban with smoking allowed in designated smoking areas. Studies evaluating smoke-free laws are scarce in Sub-Saharan Africa. Evaluation of smoke-free laws is an effective means of measuring progress towards a smoke-free society. This study assessed the level of compliance to the provisions of the current smoke-free policy using air quality measurements for fine particulate matter (PM2.5) in hospitality venues in Ghana. METHODS This was a cross-sectional observational study conducted in 2019 using a structured observational checklist complemented with air quality measurements using Dylos monitors across 152 randomly selected hospitality venues in three large cities in Ghana. RESULTS Smoking was observed in a third of the venues visited. The median indoor PM2.5 concentration was 14.6 μg/m3 (range: 5.2-349). PM2.5 concentrations were higher in venues where smoking was observed (28.3 μg/m3) compared to venues where smoking was not observed (12.3 μg/m3) (p<0.001). Hospitality locations in Accra, Ghana's capital city, had the lowest compliance levels (59.5%) and poorer air quality compared to the cities of Kumasi and Tamale. CONCLUSIONS The study shows that while smoking and SHS exposure continues in a substantial number of hospitality venues, there is a marked improvement in PM2.5 concentrations compared to earlier studies in Ghana. There is still a considerable way to go to increase compliance with the law. Efforts are needed to develop an action plan to build upon recent progress in providing smoke-free public spaces in Ghana.

Abstract
Introduction Many smokers who begin using electronic nicotine delivery systems (ENDS) report vaping in settings where they would not have smoked and believe secondhand aerosol (SHA) is simply steam. However, current understanding of how ENDS users differentiate between secondhand smoke and SHA, or how vaping norms develop, is limited. Methods We conducted in-depth, semi-structured interviews with 39 current ENDS users (dual users and former smokers, now exclusive ENDS users) from New Zealand to explore participants’ perceptions of SHA. We probed how these perceptions arose and examined implications for vaping practices and policy. We managed the data using NVivo V.11 and used a thematic analysis approach to interpret the transcripts. Results Participants had limited understanding of SHA, its constituents or its possible effects on others. They drew on the absence of harm information, and their sensory experiences and perceptions of others’ views of vaping, to support the conclusion that SHA posed few, if any, risks to bystanders. Yet despite this perception, some felt they should recognise others’ rights to clean air and most would not vape around children to avoid setting an example. Conclusions In the absence of trusted information, participants used sensory heuristics to rationalise their ENDS practices. Policy-makers face the challenge of correcting misperceptions about SHA without deterring full transition from smoking to ENDS use. They could consider including vaping in current smoke-free area policies; this measure would signal that SHA is not harmless, and could protect clean-air settings and reduce potential normalisation of vaping among non-smokers.

Abstract
BACKGROUND There are both environmental and genetic factors which are associated with multiple sclerosis (MS) development. The primary objective of this study was to examine the predictors associated with people's attitudes towards second hand smoke exposure being a risk factor for development of MS. METHODS The data set was drawn from the Health Canada: Smoking Survey conducted in 2004 and 2005 by Environics Research Group in partnership with Health Canada to survey the public in the province of British Columbia (N = 1468), Newfoundland (N = 1442), Quebec (N = 1404), Ontario (N = 1443) and Saskatchewan (N = 1413). A multilevel mixed effects logistic regression model analysis was carried out in order to determine whether people's perceptions of second hand smoking as a risk factor for MS varied based on the province of residence. RESULTS Age, sex, having a household member who smoked inside their home, if respondents were bothered by second hand smoke exposure and smoking status were associated with increased odds of people agreeing to second hand smoke exposure being a risk factor for MS development. The province of residence was also a factor in people's perceptions. CONCLUSION The study results could guide in the development of stop second hand smoking campaigns on social media, TV and bus stop shelters and enforcement of stricter policies on smoking areas. This could help raise awareness about the risk of second hand smoking and its detrimental effect on people living with MS.

Abstract
SIGNIFICANCE Secondhand tobacco smoke (SHS) exposure is a major cause of morbidity and mortality around the world. The objective of this study was to evaluate the presence of smoking in outdoor areas of public places in three largest Turkish cities (Istanbul, Ankara, and Izmir). METHOD For this cross-sectional observational study, the Turkish Statistical Institute randomly selected 10 sampling points in each city. Around each sampling point, fieldworkers visited the closest bars/nightclubs, cafes, government buildings, hospitals, restaurants, schools, shopping malls, traditional coffee houses, universities, children's playgrounds, parks and open markets. We observed smoking, ashtrays, and cigarette butts at the outdoor areas of public venues within the urban districts of each city. The fieldwork was conducted in April-May 2016. RESULTS 477 venues were observed, covering 1017 outdoor locations in which 17,737 people were observed. Smoking in outdoor areas ranged from 3.7% around schools to 90% in open markets. Ashtrays were almost ubiquitous in hospitals (95.6%), shopping malls (92.0%), and universities (90.9%). Cigarette butts were more often observed in open markets (100%), shopping malls (96%), universities (95.5%), and parks (93.3%). Smoking at outdoor areas around schools was significantly lower than around other venues. CONCLUSION Smoking in outdoor areas was common in most public places in Turkey except schools. The current indoor SHS legislation should be extended to cover adjacent outdoor areas of public venues in order to effectively protect people from SHS exposure in Turkey.

Abstract
INTRODUCTION This study aims to determine if smokers at post-secondary campuses are more likely to adhere to smoke-free zones (areas where smoking is not permitted) or smoking zones (areas where smoking is permitted) based on preference and effectiveness. METHODS A self-reported survey was developed and administered at two postsecondary institutions; Western University (smoke-free zones) and Fanshawe College (smoking zones). Smokers were asked how often they use these zones, which zone is preferred and which zone they think is more effective. A chi-squared analysis was performed to determine if there were differences in the frequency of responses. RESULTS A total of 239 surveys were collected, 119 from Western and 120 from Fanshawe. Of these, 87% of respondents at Fanshawe were aware of where they could smoke on campus, and 67% reported that they mostly or always used these spaces. At Western, significantly fewer respondents knew where to smoke (57%), and only 30% reported mostly or always using appropriate zones (p<0.05). More participants at Fanshawe indicated that they had been told by someone in authority where they could smoke (36%) compared to Western (19%, p<0.05). At Fanshawe, 63% of respondents stated that smoking zones mostly or always effectively indicated where it was appropriate to smoke on campus compared to only 18% at Western (p<0.05). Both groups indicated they preferred the zone they currently had. Finally, more participants from Fanshawe intend to quit smoking within 6 months (61% from Fanshawe vs 49% from Western, p<0.05). CONCLUSIONS Smoking zones on post-secondary campuses may be more effective and adhered to by smokers than smoke-free zones.

[PMID: 30500390 DOI: 10.1016/j.yrtph.2018.11.014] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2018] [Revised: 10/25/2018] [Accepted: 11/26/2018] [Indexed: 11/18/2022]
Abstract
In our latest update of the evidence on smoking bans and heart disease we summarize 59 studies. We take account of the underlying trends in incidence rates as far as possible by using control data in eight studies, and by adjustment based on observed trends in cases pre- and post-ban in 40 studies, being unable to make an adjustment in the remaining 11 studies. Overall, based on 62 independent estimates from the 59 studies, we estimate that bans reduce incidence by 5.0% (95% CI 3.2-6.8%), though this estimate reduces to 2.9% (0.01-5.6%) when we exclude regional estimates where national estimates are available, and studies where trend adjustment is not possible. For 25 of the studies, quadratic rather than linear adjustment is possible, but this hardly affects the overall estimates. Ban effects are somewhat greater when the pre-ban period studied is relatively short, and in smaller studies. We compare our findings with those in other recent reviews, one of which totally ignored underlying trends and results from control populations. We discuss reasons why we believe there is likely to be a true small effect of smoking bans, and weaknesses in the data which preclude reaching any very confident conclusion.

Abstract
This study evaluated the effects of partial and complete island-wide smoking bans on perinatal outcomes in Taiwan. Trends were determined in the yearly prevalence rates for preterm births and low birth weight (LBW) for a 1978 to 1997 pre-ban period, a 1998 to 2008 Phase 1 partial ban period, and a 2009 to 2016 Phase 2 complete ban period. Poisson regression with a yearly time-series model was employed to determine alterations in trends in prevalence rates for preterm births and LBW. Compared with pre-ban period, the rate ratio (RR) for Phase 1 preterm births was 0.969 (95% confidence interval [CI] = 0.968-0.971) and Phase 2 0.995 (95% CI = 0.992-0.998). The Phase 1 RR LBW fell 0.4% (95% CI = 0.2%-0.5%), but Phase 2 RR rose 1.7% (95% CI = 1.4%-2.1%). Data indicated that the risk of preterm births and LBW in Taiwan was reduced significantly after implementation of the smoking ban. These findings are in agreement with growing evidence suggesting that smoke-free legislation exerted a beneficial health effect on pregnant women and their newborn infants.

Abstract
INTRODUCTION In Canada, young adults have the highest smoking rates among all other population groups and specifically college students are at a higher risk. To implement effective policies that can prevent smoking and increase cessation, a population-specific approach is recommended. METHODS Smoking and non-smoking young adults enrolled in a college program were recruited. Participants who did not smoke were asked to complete questionnaires about their demographics, college experience and the college environment. Additionally, they completed The Perceived Stress Scale and The Center for Epidemiologic Studies - Depression Scale. Students who were current smokers completed the same questionnaires with the addition of one questionnaire about their smoking behaviors. Percentages, means and standard deviations were used to describe the variables of interest and a chi-squared analysis was performed, when possible, to test the difference in response frequency between smoking and non-smoking participants. RESULTS Differences were observed between smoking (n=65) and non-smoking students (n=214). Specifically, smokers were more likely to have a family member that smoked and to participate in binge drinking. Both groups indicated that they are unaware of campus smoking regulations; however smokers were more opposed to implementing smoke-free policies. CONCLUSIONS College students are unaware of campus smoking regulations. The descriptive information and differences observed between smoking and non-smoking students in this study should be taken into consideration when developing future smoking regulations/policies on college campuses.

Changes in smoking prevalence after the enforcement of smoking control regulations in urban Shanghai, China: Findings from two cross-sectional surveys. Tob Induc Dis 2018; 16:27. [PMID: 31516427 PMCID: PMC6659492 DOI: 10.18332/tid/91095] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2017] [Revised: 04/09/2018] [Accepted: 05/16/2018] [Indexed: 11/24/2022] Open
Abstract
INTRODUCTION The Smoking Control Regulation in Public Places (hereafter, the ‘regulations’) has been implemented in Shanghai since 2010. This study explores the changes in smoking prevalence and its influencing factors among urban Shanghai residents. METHODS Two rounds of household investigations (the Health Status and Health Service Utilization Survey) were carried out using a multistage probability proportionate-to-size sampling method in an urbanized district in 2010 and 2015. Descriptive and logistic regression analyses were applied to the statistics. RESULTS From 2010 to 2015, the standardized current smoking rate fell from 24.8% to 19.1% (38.3% to 32.0% among men, and 1.9% to 1.4% among women). Meanwhile, the standardized smoking cessation rate increased from 18.1% to 23.3%. Smoking prevalence in respondents aged 45 to 59 years was still higher than that of other age groups. Changes in smoking prevalence and cessation rates were more obvious in respondents aged 30–44 and over 75 years. Sex, age, education, marital status, and alcohol use were influencing factors of current smoking, while sex, age and alcohol use were influencing factors of smoking cessation. CONCLUSIONS The implementation of smoking control regulations may be beneficial for reducing smoking and increasing smoking cessation, especially among middle-aged and older men. Nevertheless, tobacco control in urban Shanghai still faces huge challenges. Therefore, more targeted and comprehensive measures should be taken.

Abstract
BACKGROUND A comprehensive smoke-free air law was enacted on June 1, 2012 in most of Marion County, Indiana, including all of the City of Indianapolis. We evaluated changes in acute myocardial infarction (AMI) admission rates in Indianapolis and Marion County before compared to after the law. METHODS We collected AMI admissions from five Marion County hospitals between May 2007 and December 2014. We used Poisson regression to evaluate the overall effects of the law on monthly AMI hospitalizations, adjusting for month, seasonality, meteorology, air pollution, and hospital utilization. We tested the interactions between the law and AMI risk factors on monthly AMI admission rates to identify subpopulations for which the effects might be stronger. RESULTS Monthly AMI admissions declined 20% (95% CI 14-25%) in Marion County and 25% (95% CI 20-29%) in Indianapolis after the law was implemented. We observed decreases among never (21%, 95% CI 13-29%), former (28%, 95% CI 21-34%), and current smokers (26%, 95% CI 11-38%); Medicaid beneficiaries (19%, 95% CI 9-29%) and non-beneficiaries (26%, 95% CI 20-31%). We observed decreases among those with a history of diabetes (Yes: 22%, 95% CI 14-29%; No: 25%, 95% CI 18-31%), congestive heart failure (Yes: 23%, 95% CI 16-30%; No: 24%, 95% CI 17-31%), and hypertension (Yes: 23%, 95% CI 17-28%: No: 26%, 95% CI 15-36%). CONCLUSIONS We observed decreases in AMI admissions comparable with previous studies. We identified subpopulations who benefitted from the law, such as former and current smokers, and those without comorbidities such as congestive heart failure and hypertension.

Abstract
On January 11, 2009, a comprehensive smoking ban was implemented in Taiwan. The aim of this study was to evaluate the effect of this ban on hospital admissions for ischemic heart disease (IHD). Trends in the country-level monthly hospital admission rates for IHD were determined and frequency compared to other conditions such as control conditions cholecystitis, bowel obstruction, and appendicitis from January 1997 (1 year before the first phase of smoke-free laws was implemented) to December 2012 (3 years after the second phase of the ban). Poisson regression with a monthly time-series model was used to determine alterations in the trend of admission rates for IHD with comparison to rates of other disorders after the ban. Hospital admissions for IHD decreased by 0.8% (incidence rate ratio [RR]: 0.992; 95% confidence interval [CI] = 0.991-0.994) and 1.1% (incidence RR: 0.989; 95% CI = 0.988-0.991) following the first (September 19, 1997 to January 10, 2009) and second (January 11, 2009 to December 31, 2012) phases of the ban, respectively, compared with those prior to the pre-ban period, the corresponding values for the control conditions were 0.6% (95% CI = 0.5%-0.7%) and 0.7% (95% CI = 0.6%-0.9%). The admission rates significantly fell for both men and women and for all examined age categories after both first and second phases of the ban. The present findings provide evidence of a significant reduction in hospital admissions for IHD in Taiwan following smoking bans.

Abstract
Smoke-free legislation in indoor public places has concentrated smokers in the areas outside building entrances or other outdoor areas. This study assessed the drift of second-hand smoke between outdoor and indoor areas of cafés and restaurants in Barcelona, Spain, and characterized the exposure on outdoor terraces. Using a cross-sectional design, we monitored vapor-phase nicotine in indoor areas and outside entrances simultaneously (n=47), and on some outdoor terraces (n=51). We computed the median nicotine concentration and interquartile range (IQR) to describe the data and performed multivariate analysis to describe nicotine concentration and its determinants. The overall median nicotine concentration indoors was 0.65µg/m(3) (IQR: 0.29-1.17µg/m(3)), with significant differences based on the number of smokers at the entrance (p=0.039). At outside entrances, the overall median nicotine concentration was 0.41µg/m(3) (IQR: 0.21-1.17µg/m(3)). The nicotine concentrations indoors and at the corresponding outside entrances were not significantly different, and the multivariate analysis confirmed the relationship between these variables. On terraces, the overall median nicotine concentration was 0.54µg/m(3) (IQR: 0.25-1.14µg/m(3)), but it increased to 0.60µg/m(3) when a tobacco smell was perceived, 0.72µg/m(3) on closed terraces, 1.24µg/m(3) when there were >6 smokers, and 1.24µg/m(3) when someone smoked >20min. Multivariate analysis confirmed the outdoor terrace area, the season, the type of enclosure, and the number of smokers as the most relevant variables explaining nicotine concentration (R(2)=0.396). These findings show that second-hand smoke exposure exists in indoor areas due to smokers smoking at the outside entrances. In addition, exposure may occur on outdoor terraces when smokers are present and the terrace is enclosed to some extent. Thus, the current Spanish law does not fully protect non-smokers from second-hand smoke and supports extending regulation to some outdoor areas.

Abstract
BACKGROUND Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and the smoking behaviour of those populations they affect. Since the first version of this review in 2010, more countries have introduced national smoking legislation banning indoor smoking. OBJECTIVES To assess the effects of legislative smoking bans on (1) morbidity and mortality from exposure to secondhand smoke, and (2) smoking prevalence and tobacco consumption. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL and reference lists of included studies. We also checked websites of various organisations. Date of most recent search; February 2015. SELECTION CRITERIA We considered studies that reported legislative smoking bans affecting populations. The minimum standard was having an indoor smoking ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. Our search included a broad range of research designs including: randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before-and-after studies, interrupted time series as defined by the Cochrane Effective Practice and Organisation of Care Group, and uncontrolled pre- and post-ban data. DATA COLLECTION AND ANALYSIS One author extracted characteristics and content of the interventions, participants, outcomes and methods of the included studies and a second author checked the details. We extracted health and smoking behaviour outcomes. We did not attempt a meta-analysis due to the heterogeneity in design and content of the studies included. We evaluated the studies using qualitative narrative synthesis. MAIN RESULTS There are 77 studies included in this updated review. We retained 12 studies from the original review and identified 65 new studies. Evidence from 21 countries is provided in this update, an increase of eight countries from the original review. The nature of the intervention precludes randomized controlled trials. Thirty-six studies used an interrupted time series study design, 23 studies use a controlled before-and-after design and 18 studies are before-and-after studies with no control group; six of these studies use a cohort design. Seventy-two studies reported health outcomes, including cardiovascular (44), respiratory (21), and perinatal outcomes (7). Eleven studies reported national mortality rates for smoking-related diseases. A number of the studies report multiple health outcomes. There is consistent evidence of a positive impact of national smoking bans on improving cardiovascular health outcomes, and reducing mortality for associated smoking-related illnesses. Effects on respiratory and perinatal health were less consistent. We found 24 studies evaluating the impact of national smoke-free legislation on smoking behaviour. Evidence of an impact of legislative bans on smoking prevalence and tobacco consumption is inconsistent, with some studies not detecting additional long-term change in existing trends in prevalence. AUTHORS' CONCLUSIONS Since the first version of this review was published, the current evidence provides more robust support for the previous conclusions that the introduction of a legislative smoking ban does lead to improved health outcomes through reduction in SHS for countries and their populations. The clearest evidence is observed in reduced admissions for acute coronary syndrome. There is evidence of reduced mortality from smoking-related illnesses at a national level. There is inconsistent evidence of an impact on respiratory and perinatal health outcomes, and on smoking prevalence and tobacco consumption.

Abstract
BACKGROUND Legislations banning smoking in indoor public places and workplaces are being implemented worldwide to protect the population from secondhand smoke exposure. Several studies have reported reductions in hospitalizations for acute coronary events following the enactment of smoke-free laws. OBJECTIVE We set out to conduct a systematic review and meta-analysis of epidemiologic studies examining how legislations that ban smoking in indoor public places impact the risk of acute coronary events. METHODS We searched MEDLINE, EMBASE, and relevant bibliographies including previous systematic reviews for studies that evaluated changes in acute coronary events, following implementation of smoke-free legislations. Studies were identified through December 2013. We pooled relative risk (RR) estimates for acute coronary events comparing post- vs. pre-legislation using inverse-variance weighted random-effects models. RESULTS Thirty-one studies providing estimates for 47 locations were included. The legislations were implemented between 1991 and 2010. Following the enactment of smoke-free legislations, there was a 12 % reduction in hospitalizations for acute coronary events (pooled RR: 0.88, 95 % CI: 0.85-0.90). Reductions were 14 % in locations that implemented comprehensive legislations compared to an 8 % reduction in locations that only had partial restrictions. In locations with reductions in smoking prevalence post-legislation above the mean (2.1 % reduction) there was a 14 % reduction in events compared to 10 % in locations below the mean. The RRs for acute coronary events associated with enacting smoke-free legislation were 0.87 vs. 0.89 in locations with smoking prevalence pre-legislation above and below the mean (23.1 %), and 0.87 vs. 0.89 in studies from the Americas vs. other regions. CONCLUSION The implementation of smoke-free legislations was related to reductions in acute coronary event hospitalizations in most populations evaluated. Benefits are greater in locations with comprehensive legislations and with greater reduction in smoking prevalence post-legislation. These cardiovascular benefits reinforce the urgent need to enact and enforce smoke-free legislations that protect all citizens around the world from exposure to tobacco smoke in public places.

Abstract
We update an earlier review of smoking bans and heart disease, restricting attention to admissions for acute myocardial infarction. Forty-five studies are considered. New features of our update include consideration of non-linear trends in the underlying rate, a modified trend adjustment method where there are multiple time periods post-ban, comparison of estimates based on changes in rates and numbers of cases, and comparison of effect estimates according to post-ban changes in smoking restrictiveness. Using a consistent approach to derive ban effect estimates, taking account of linear time trends and control data, the reduction in risk following a ban was estimated as 4.2% (95% confidence interval 1.8-6.5%). Excluding regional estimates where national estimates are available, and studies where trend adjustment was not possible, the estimate reduced to 2.6% (1.1-4.0%). Estimates were little affected by non-linear trend adjustment, where possible, or by basing estimates on changes in rates. Ban effect estimates tended to be greater in smaller studies, and studies with greater post-ban changes in smoking restrictiveness. Though the findings suggest a true effect of smoking bans, uncertainties remain, due to the weakness of much of the evidence, the small estimated effect, and various possibilities of bias.

Abstract
BACKGROUND Children's exposure to other people's cigarette smoke (environmental tobacco smoke, or ETS) is associated with a range of adverse health outcomes for children. Parental smoking is a common source of children's exposure to ETS. Older children are also at risk of exposure to ETS in child care or educational settings. Preventing exposure to cigarette smoke in infancy and childhood has significant potential to improve children's health worldwide. OBJECTIVES To determine the effectiveness of interventions aiming to reduce exposure of children to ETS. SEARCH METHODS We searched the Cochrane Tobacco Addiction Group Specialized Register and conducted additional searches of the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PsycINFO, EMBASE, CINAHL, ERIC, and The Social Science Citation Index & Science Citation Index (Web of Knowledge). Date of the most recent search: September 2013. SELECTION CRITERIA Controlled trials with or without random allocation. Interventions must have addressed participants (parents and other family members, child care workers and teachers) involved with the care and education of infants and young children (aged 0 to 12 years). All mechanisms for reduction of children's ETS exposure, and smoking prevention, cessation, and control programmes were included. These include health promotion, social-behavioural therapies, technology, education, and clinical interventions. DATA COLLECTION AND ANALYSIS Two authors independently assessed studies and extracted data. Due to heterogeneity of methodologies and outcome measures, no summary measures were possible and results were synthesised narratively. MAIN RESULTS Fifty-seven studies met the inclusion criteria. Seven studies were judged to be at low risk of bias, 27 studies were judged to have unclear overall risk of bias and 23 studies were judged to have high risk of bias. Seven interventions were targeted at populations or community settings, 23 studies were conducted in the 'well child' healthcare setting and 24 in the 'ill child' healthcare setting. Two further studies conducted in paediatric clinics did not make clear whether the visits were to well or ill children, and another included both well and ill child visits. Thirty-six studies were from North America, 14 were in other high income countries and seven studies were from low- or middle-income countries. In only 14 of the 57 studies was there a statistically significant intervention effect for child ETS exposure reduction. Of these 14 studies, six used objective measures of children's ETS exposure. Eight of the studies had a high risk of bias, four had unclear risk of bias and two had a low risk of bias. The studies showing a significant effect used a range of interventions: seven used intensive counselling or motivational interviewing; a further study used telephone counselling; one used a school-based strategy; one used picture books; two used educational home visits; one used brief intervention and one study did not describe the intervention. Of the 42 studies that did not show a significant reduction in child ETS exposure, 14 used more intensive counselling or motivational interviewing, nine used brief advice or counselling, six used feedback of a biological measure of children's ETS exposure, one used feedback of maternal cotinine, two used telephone smoking cessation advice or support, eight used educational home visits, one used group sessions, one used an information kit and letter, one used a booklet and no smoking sign, and one used a school-based policy and health promotion. In 32 of the 57 studies, there was reduction of ETS exposure for children in the study irrespective of assignment to intervention and comparison groups. One study did not aim to reduce children's tobacco smoke exposure, but rather aimed to reduce symptoms of asthma, and found a significant reduction in symptoms in the group exposed to motivational interviewing. We found little evidence of difference in effectiveness of interventions between the well infant, child respiratory illness, and other child illness settings as contexts for parental smoking cessation interventions. AUTHORS' CONCLUSIONS While brief counselling interventions have been identified as successful for adults when delivered by physicians, this cannot be extrapolated to adults as parents in child health settings. Although several interventions, including parental education and counselling programmes, have been used to try to reduce children's tobacco smoke exposure, their effectiveness has not been clearly demonstrated. The review was unable to determine if any one intervention reduced parental smoking and child exposure more effectively than others, although seven studies were identified that reported motivational interviewing or intensive counselling provided in clinical settings was effective.

Abstract
Objective To evaluate the association of a nationwide comprehensive smoking ban (CSB) and tobacco tax increase (TTI) on the risk of acute myocardial infarctions (AMI) in Panama for the period of 2006 – 2010 using hospital admissions data. Methods Data of AMI cases was gathered from public and private hospitals in the country for the period of January 1, 2006 to December 31, 2010. The number of AMI cases was calculated on a monthly basis. The risk of AMI was estimated for the pre-CSB period (January 2006 to April 2008) and was used as a reference point. Three post-intervention periods were examined: (1) post-CSB from May 2008 to April 2009 (12 months); (2) post-CSB from May 2009 to November 2009 (7 months); and (3) post-TTI from December 2009 to December 2010 (13 months). Relative risks (RR) of AMI were estimated for each post intervention periods by using a Poisson regression model. Mortality registries for the country attributed to myocardial infarction (MI) were obtained from January 2001 to December 2012. The annual percentage change (APC) of the number of deaths from MI was calculated using Joinpoint regression analysis. Results A total sample size of 2191 AMI cases was selected (monthly mean number of cases 36.52±8.24 SD). Using the pre-CSB as a reference point (RR = 1.00), the relative risk of AMI during the first CSB period, the second CSB period and post-TTI were 0.982, 1.049, and 0.985, respectively. The APC of deaths from MI from January 2001 to April 2008 was 0.5%. From January 2001 to June 2010 the APC trend was 0.47% and from July 2010 to December 2012 the APC was –0.3%. Conclusions The implementation of a CSB and TTI in Panama were associated with a decrease in tobacco consumption and a reduction of the RR of AMI.

Abstract
OBJECTIVES This is the first, to my knowledge, multistate, county-level analysis of Healthcare Cost and Utilization Project state inpatient data to examine the relationship between smoke-free laws and asthma discharges. METHODS I used treatment and control groups to examine the effects of state and county or city smoke-free laws separately and together (2002-2009). I compared quarterly county-level discharge rates before and after the implementation of 12 state smoke-free laws, accounting for counties with preexisting county or city smoke-free laws and using the data from 5 states without state smoke-free laws as a control group. I used difference-in-differences models, controlling for year and state fixed effects, state cigarette taxes, seasonality, and numerous county-level factors. RESULTS I observed statistically significant reductions in asthma discharges after the implementation of county smoke-free laws but no statistically significant effect of state laws besides the effect of county laws or of state laws alone. There was also no statistically significant effect of any smoke-free law on appendicitis discharges. CONCLUSIONS It may be unwise to pursue state smoke-free laws where they have yet to pass; rather, efforts might be better focused at the local level, where there is evidence of a significant impact.

Abstract
Policies limiting exposure to cigarette smoke have been associated with reduced hospitalizations for heart attacks, but little is known about the impact of smoking bans on other health conditions and whether findings from individual communities generalize to other areas. We investigated the association between smoking bans targeting workplaces, restaurants, and bars passed throughout the United States during 1991-2008 and hospital admissions for smoking-related illnesses-acute myocardial infarction and chronic obstructive pulmonary disease-among Medicare beneficiaries age sixty-five or older. Risk-adjusted hospital admission rates for acute myocardial infarction fell 20-21 percent thirty-six months following implementation of new restaurant, bar, and workplace smoking bans. Admission rates for chronic obstructive pulmonary disease fell 11 percent where workplace smoking bans were in place and 15 percent where bar smoking bans were present. By contrast, very little effect was found for hospitalization for gastrointestinal hemorrhage and hip fracture-two conditions largely unrelated to smoking and examined as points of comparison. These findings provide further support for the public health benefits of laws that limit exposure to tobacco smoke.

Abstract
Background Comprehensive smoke-free legislation has been implemented in many countries. The current study quantitatively examined the reduction in risk of acute myocardial infarction (MI) occurrence following the legislations and the relationship with the corresponding smoking prevalence decrease. Methods PubMed, EMBASE, and Google Scholar databases and bibliographies of relevant studies and reviews were searched for potential original studies published from January 1, 2004, through October 31, 2011. Meta-analysis was performed using a random effect model to estimate the overall effects of the smoking-free legislations. Meta-regression was used to investigate possible causes of heterogeneity in risk estimates. Results A total of 18 eligible studies with 44 estimates of effect size were used in this study. Meta-analysis produced a pooled estimate of the relative risk of 0.87 (95% confidence interval (CI): 0.84 to 0.91). There was significant heterogeneity in the risk estimates (overall I2 = 96.03%, p<0.001). In meta-regression analysis, studies with greater smoking prevalence decrease produced larger relative risk (adjusted coefficient −0.027, 95% CI: -0.049 to −0.006, p=0.014). Conclusion Smoke-free legislations in public and work places were associated with significant reduction in acute MI risk, which might be partly attributable to reduced smoking prevalence.

Abstract
Background This is the first study to have examined the effect of smoking bans on hospitalizations in the Atlantic Canadian socio-economic, cultural and climatic context. On June 1, 2003 Prince Edward Island (PEI) enacted a province-wide smoking ban in public places and workplaces. Changes in hospital admission rates for cardiovascular (acute myocardial infarction, angina, and stroke) and respiratory (chronic obstructive pulmonary disease and asthma) conditions were examined before and after the smoking ban. Methods Crude annual and monthly admission rates for the above conditions were calculated from April 1, 1995 to December 31, 2008 in all PEI acute care hospitals. Autoregressive Integrated Moving Average time series models were used to test for changes in mean and trend of monthly admission rates for study conditions, control conditions and a control province after the comprehensive smoking ban. Age- and sex-based analyses were completed. Results The mean rate of acute myocardial infarctions was reduced by 5.92 cases per 100,000 person-months (P = 0.04) immediately after the smoking ban. The trend of monthly angina admissions in men was reduced by −0.44 cases per 100,000 person-months (P = 0.01) in the 67 months after the smoking ban. All other cardiovascular and respiratory admission changes were non-significant. Conclusions A comprehensive smoking ban in PEI reduced the overall mean number of acute myocardial infarction admissions and the trend of angina hospital admissions.

Abstract
In this review, we have sought to examine the epidemiological, basic science, and public health data regarding the association between second-hand smoke (SHS) exposure and the development of coronary heart disease (CHD). SHS increases the risk of CHD by 25-30% according to multiple cohort, case-control, and meta-analytical studies. Physiologic and basic science research suggest that the mechanisms by which SHS affects the cardiovascular system are multiple and include increased thrombogenesis and low-density lipoprotein oxidation, decreased exercise tolerance, dysfunctional flow-mediated vasodilatation, and activation of inflammatory pathways with concomitant oxidative damage and impaired vascular repair. As a result, chronic exposure promotes atherogenesis and the development of cardiovascular disease, increasing the risk of having an acute coronary syndrome (ACS). With the implementation of statewide and nationwide public smoke-free legislation across the United States and Europe, respectively, over the last 10-15 years, there has been a significant and reciprocal decline in the incidence of emergency admissions for ACS by an average 17% despite persistent attempts on the part of the tobacco industry to diminish the correlation between SHS exposure and CHD. These findings underscore the importance of the effects of smoking legislation on community health.

Abstract
BACKGROUND Secondhand smoke causes cardiovascular and respiratory disease. Smoke-free legislation is associated with a lower risk of hospitalization and death from these diseases. METHODS AND RESULTS Random-effects meta-analysis was conducted by law comprehensiveness to determine the relationship between smoke-free legislation and hospital admission or death from cardiac, cerebrovascular, and respiratory diseases. Studies were identified by using a systematic search for studies published before November 30, 2011 with the use of the Science Citation Index, Google Scholar, PubMed, and Embase and references in identified articles. Change in hospital admissions (or deaths) in the presence of a smoke-free law, duration of follow-up, and law comprehensiveness (workplaces only; workplaces and restaurants; or workplaces, restaurants, and bars) were recorded. Forty-five studies of 33 smoke-free laws with median follow-up of 24 months (range, 2-57 months) were included. Comprehensive smoke-free legislation was associated with significantly lower rates of hospital admissions (or deaths) for all 4 diagnostic groups: coronary events (relative risk, 0.848; 95% confidence interval 0.816-0.881), other heart disease (relative risk, 0.610; 95% confidence interval, 0.440-0.847), cerebrovascular accidents (relative risk, 0.840; 95% confidence interval, 0.753-0.936), and respiratory disease (relative risk, 0.760; 95% confidence interval, 0.682-0.846). The difference in risk following comprehensive smoke-free laws does not change with longer follow-up. More comprehensive laws were associated with larger changes in risk. CONCLUSIONS Smoke-free legislation was associated with a lower risk of smoking-related cardiac, cerebrovascular, and respiratory diseases, with more comprehensive laws associated with greater changes in risk.

Abstract
Restrictions on smoking in public places have become increasingly widespread in the United States, particularly since the year 2005. National-scale studies in Europe and local-scale studies in the United States have found decreases in hospital admissions for acute myocardial infarction (AMI) following smoking bans. The authors analyzed AMI admission rates for the years 1999-2008 in 387 US counties that enacted comprehensive smoking bans across 9 US states, using a study population of approximately 6 million Medicare enrollees aged 65 years or older. Effects of smoking bans on AMI admissions were estimated by using Poisson regression with linear and nonlinear adjustment for secular trend and random effects at the county level. Under the assumption of linearity in the secular trend of declining AMI, smoking bans were associated with a statistically significant ban-associated decrease in admissions for AMI in the 12 months following the ban. However, the estimated effect was attenuated to nearly zero when the assumption of linearity in the underlying trend was relaxed. This analysis demonstrates that estimation of potential health benefits associated with comprehensive smoking bans is challenged by the need to adjust for nonlinearity in secular trend.

Abstract
BACKGROUND Exposure to secondhand smoke is associated with an increased risk of acute myocardial infarction (AMI). The positive impact of a smoking ban on AMI hospitalization rates has been demonstrated both inside and outside Europe. A national smoking ban (SB) was implemented in Denmark on 15 August 2007. PURPOSE To evaluate the impact of the Danish SB on hospital admissions for AMI. METHODS Poisson regression models were used to analyse changes over time in AMI-admissions in Denmark. We investigated a seven year period: five years before and two years after implementation of the SB. We accounted for the variation in the population size and for seasonal trends. Potential confounders included were: gender, age and the incidence of type 2 diabetes (T2D). RESULTS A significant reduction in the number of AMI-admissions was found in the last three years of the study period after adjusting for the potential confounders. The significant reductions were found one year before the SB (relative rate (RR) = 0.86, 95% confidence interval (CI) 0.79-0.94), one year after the SB (RR = 0.77, 95% CI 0.71-0.85) and two years after the SB (RR = 0.77, 95% CI 0.70-0.84). CONCLUSIONS A significant reduction in the number of AMI-admissions was found already one year before the SB after adjustment for the incidence of T2D. The results differ from most results found in similar studies throughout the world and may be explained by the incremental enactment of SBs in Denmark and the implementation of a nation-wide ban on industrially produced trans-fatty acids in food in 2004.

Abstract
BACKGROUND Poor lifestyle behaviors, including suboptimal diet, physical inactivity, and tobacco use, are leading causes of preventable diseases globally. Although even modest population shifts in risk substantially alter health outcomes, the optimal population-level approaches to improve lifestyle are not well established. METHODS AND RESULTS For this American Heart Association scientific statement, the writing group systematically reviewed and graded the current scientific evidence for effective population approaches to improve dietary habits, increase physical activity, and reduce tobacco use. Strategies were considered in 6 broad domains: (1) Media and educational campaigns; (2) labeling and consumer information; (3) taxation, subsidies, and other economic incentives; (4) school and workplace approaches; (5) local environmental changes; and (6) direct restrictions and mandates. The writing group also reviewed the potential contributions of healthcare systems and surveillance systems to behavior change efforts. Several specific population interventions that achieved a Class I or IIa recommendation with grade A or B evidence were identified, providing a set of specific evidence-based strategies that deserve close attention and prioritization for wider implementation. Effective interventions included specific approaches in all 6 domains evaluated for improving diet, increasing activity, and reducing tobacco use. The writing group also identified several specific interventions in each of these domains for which current evidence was less robust, as well as other inconsistencies and evidence gaps, informing the need for further rigorous and interdisciplinary approaches to evaluate population programs and policies. CONCLUSIONS This systematic review identified and graded the evidence for a range of population-based strategies to promote lifestyle change. The findings provide a framework for policy makers, advocacy groups, researchers, clinicians, communities, and other stakeholders to understand and implement the most effective approaches. New strategic initiatives and partnerships are needed to translate this evidence into action.

Abstract
BACKGROUND Studies have shown that laws banning smoking in public places reduce exposure to secondhand smoke, but the impact of such laws on exposure to smoke outside the home and on household smoking policies has not been well documented. The goal of this study was to evaluate the effects of 2009 Wisconsin Act 12, a statewide smoke-free law enacted in July 2010, among participants in the Survey of the Health of Wisconsin (SHOW). METHODS Smoking history and demographic information was gathered from 1341 survey participants from 2008 to 2010. Smoking behaviors of independent samples of participants surveyed before and after the legislation was enacted were compared. RESULTS The smoking ban was associated with a reduction of participants reporting exposure to smoke outside the home (from 55% to 32%; P<0.0001) and at home (13% to 7%; P=0.002). The new legislation was associated with an increased percentage of participants with no-smoking policies in their households (from 74% to 80%; P=.04). The results were stronger among participants who were older, wealthier, and more educated. CONCLUSION Smoke-free legislation appears to reduce secondhand smoke exposure and to increase no-smoking policies in households. Further research should be conducted to see if these effects are maintained.

Abstract
Rapid declines in hospital admissions for acute myocardial infarction (AMI) following smoke-free ordinances have been reported in smaller communities. The AMI mortality rate among persons age 45 + years (deaths per 100,000 persons, age-standardized to the 2000 US population) in the 3 years before adoption of the smoke-free ordinance (the expected rate) was compared with the rate observed in the first full year after the ban (the target year) in six US states. Target-year declines were also compared to those in states without smoking bans. Target-year declines in AMI mortality in California (2.0%), Utah (7.7%) and Delaware (8.1%) were not significantly different from the expected declines (P = 0.16, 0.43 and 0.89, respectively). In South Dakota AMI mortality increased 8.9% in the target year (P = 0.007). Both a 9% decline in Florida and a 12% decline in New York in the 2004 target year exceeded the expected declines (P = 0.04 and P < 0.0002, respectively) but were not significantly different (P = 0.55 and 0.08, respectively) from the 9.8% decline that year in the 44 states without bans. Smoke-free ordinances provide a healthy indoor environment, but their implementation in six states had little or no immediate measurable effect on AMI mortality.

Impact of tobacco control interventions on smoking initiation, cessation, and prevalence: a systematic review. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2012; 2012:961724.

Abstract
Background. Policymakers need estimates of the impact of tobacco control (TC) policies to set priorities and targets for reducing tobacco use. We systematically reviewed the independent effects of TC policies on smoking behavior. Methods. We searched MEDLINE (through January 2012) and EMBASE and other databases through February 2009, looking for studies published after 1989 in any language that assessed the effects of each TC intervention on smoking prevalence, initiation, cessation, or price participation elasticity. Paired reviewers extracted data from studies that isolated the impact of a single TC intervention. Findings. We included 84 studies. The strength of evidence quantifying the independent effect on smoking prevalence was high for increasing tobacco prices and moderate for smoking bans in public places and antitobacco mass media campaigns. Limited direct evidence was available to quantify the effects of health warning labels and bans on advertising and sponsorship. Studies were too heterogeneous to pool effect estimates. Interpretations. We found evidence of an independent effect for several TC policies on smoking prevalence. However, we could not derive precise estimates of the effects across different settings because of variability in the characteristics of the intervention, level of policy enforcement, and underlying tobacco control environment.

Reshuffling and relocating: the gendered and income-related differential effects of restricting smoking locations. JOURNAL OF ENVIRONMENTAL AND PUBLIC HEALTH 2012; 2012:907832.

Abstract
This study investigates secondhand smoke (SHS) exposure and management in the context of smoking location restrictions, for nonsmokers, former, and current smokers. A purposive sample of 47 low income and non-low-income men and women of varied smoking statuses was recruited to participate in a telephone interview or a focus group. Amidst general approval of increased restrictions there were gendered patterns of SHS exposure and management, and effects of SHS policies that reflect power, control, and social roles that need to be considered as policies are developed, implemented and monitored. The experience of smoking restrictions and the management of SHS is influenced by the social context (relationship with a partner, family member, or stranger), the space of exposure (public or private, worksite), the social location of individuals involved (gender, income), and differential tolerance to SHS. This confluence of factors creates differing unintended and unexpected consequences to the social and physical situations of male and female smokers, nonsmokers, and former smokers. These factors deserve further study, in the interests of informing the development of future interventions and policies restricting SHS.

Abstract
AIMS To study the effects of smoking restrictions in Germany on coronary syndromes and their associated costs. METHODS AND RESULTS All German states implemented laws partially restricting smoking in the public and hospitality sectors between August 2007 and July 2008. We conducted a before-and-after study to examine trends for the hospitalization rate for angina pectoris and acute myocardial infarction (AMI) for an insurance cohort of 3,700,384 individuals 30 years and older. Outcome measures were hospitalization rates for coronary syndromes, and hospitalization costs. Mean age of the cohort was 56 years, and two-thirds were female. Some 2.2 and 1.1% persons were hospitalized for angina pectoris and AMI, respectively, during the study period from January 2004 through December 2008. Law implementation was associated with a 13.3% (95% confidence interval 8.2, 18.4) decline in angina pectoris and an 8.6% (5.0, 12.2) decline in AMI after 1 year. Hospitalization costs also decreased significantly for the two conditions-9.6% (2.5, 16.6) for angina pectoris and 20.1% (16.0, 24.2) for AMI at 1 year following law implementation. Assuming the law caused the observed declines, it prevented 1,880 hospitalizations and saved 7.7 million Euros in costs for this cohort during the year following law implementation. CONCLUSIONS Partial smoking restrictions in Germany were followed by reductions in hospitalization for angina pectoris and AMI, declines that continued through 1 year following these laws and resulted in substantial cost savings. Strengthening the laws could further reduce morbidity and costs from acute coronary syndromes in Germany.

Abstract
BACKGROUND Stimulated by the WHO Framework Convention on Tobacco Control, many countries in Latin America adopted comprehensive smoke-free policies. In March 2006, Uruguay became the first Latin American country to adopt 100% smoke-free national legislation, which ended smoking in all indoor public places and workplaces, including restaurants and bars. The objective of this study was to evaluate trends in hospital admissions for cardiovascular disease 2 years before and 2 years after the policy was implemented in Uruguay. METHODS Reports of hospital admissions for acute myocardial infarction (AMI) (International Classification of Disease-10 I21) from 37 hospitals (79% of all hospital admissions in the country), representing the period 2 years before and 2 years after the adoption of a nationwide smoke-free policy in Uruguay (between 1 March 2004 and 29 February 2008), were reviewed. A time series analysis was undertaken to compare the average monthly number of events of hospital admission for AMI before and after the smoke-free law. RESULTS A total of 7949 hospital admissions for AMI were identified during the 4-year study period. Two years after the smoke-free policy was enacted, hospital admissions for AMI fell by 22%. The same pattern and roughly the same magnitude of reduction in AMI admissions were observed for patients seen in public and private hospitals, men, women and people aged 40-65 years and older than 65 years. CONCLUSIONS The national smoke-free policy implemented in Uruguay in 2006 was associated with a significant reduction in hospital admissions for AMI.

Abstract
Evidence that smoking area restrictions and raising cigarette taxes affect smokers’ behavior of seeking help in cessation is limited. The authors conducted a case-control study of 200 participants in Taipei City, Taiwan, from December 2008 to June 2009 to evaluate the association between knowledge on legislation and the behavior of seeking help in smoking cessation. They compared smokers who sought assistance in clinics/classes and smokers who did not, matching for age, gender, and recruitment time. In a univariate model, both banning smoking and increasing prices had positive effects on smokers’ behavior, but the effect size of the latter was larger ( P = .021). A better knowledge of the regulations was associated with cessation effort (odds ratio [OR] = 2.74; 95% confidence interval [CI] = 1.44-5.23), as were being more influenced by increased prices (OR = 2.44; 95% CI = 1.38-4.34) and by smoking bans (OR = 2.32; 95% CI = 1.29-4.16). Increased knowledge of the regulations is associated with seeking help for smoking.

Abstract
BACKGROUND A ban on smoking in the workplace was introduced in Ireland on March 29, 2004. As exposure to secondhand smoke has been implicated in the development of coronary disease, this might impact the incidence of acute coronary syndromes (ACS). HYPOTHESIS The smoking ban was associated with a decreased rate of hospital admissions for ACS. METHODS We analyzed data collected in a registry of all patients admitted to hospital with ACS in the southwest of Ireland, catchment population 620 525, from March 2003 until March 2007. RESULTS In the year following implementation of the ban, there was a significant 12% reduction in ACS admissions (177.9 vs 205.9/100,000; 95% confidence interval [CI]: 164.0-185.1, P = 0.002). This reduction was due to fewer events occurring among men (281.5 vs 233.5, P = 0.0011) and current smokers (408 vs 302 admissions, P < 0.0001). There was no change in the rate of admissions for ACS in the following year (174.3/100,000; 95% CI: 164.0-185.1, P > 0.1). However, a further 13% reduction was observed between March 2006 and March 2007 (149.2; 95% CI: 139.7-159.2). Variation in admissions with time as a continuous variable also demonstrated a reduction on implementation of the smoking ban. CONCLUSIONS A national ban on smoking in public places was associated with an early significant decrease in hospital admissions for ACS, suggesting a rapid effect of banning smoking in public places on ACS. A further reduction of similar magnitude 2 years after implementation of the ban is consistent with a longer-term effect that should be further examined in long-term studies.

Abstract
Background: Interventions aimed at reducing the number of smokers are generally believed to be cost effective. However as the cost of the interventions should be paid up front whereas the gains in life years only appear in the future – the budgetary consequences might be a barrier to implementing such interventions. Aims: The aim of the present paper was to assess the long-term cost effectiveness as well as the short-term (10 years) budget consequences of cessation programmes and a smoking ban in enclosed public places. Methods: We develop a population-based Markov model capable of analyzing both interventions and assess long-term costs effectiveness as well as short-term budgetary consequences and outcome gains. The smoking cessation programme model was based on data from the Danish National Smoking Cessation Database (SCDB), while the model of the smoking ban was based on effect estimates found in the literature. Results: On a population level the effect of a smoking ban has the largest potential compared with the effect of smoking cessation programmes. Our results suggest that smoking cessation programmes are cost saving and generate life-years, whereas the costs per life-year gained by a smoking ban are 40,645 to 64,462 DKK (100 DKK = €13.4). These results are conservative as they do not include the healthcare cost saving related to reduced passive smoking. Conclusions: Our results indicate that smoking cessation programmes and a smoking ban in enclosed public places both in the short term and the long term are cost-effective strategies compared with the status quo.

Abstract
BACKGROUND Smoking ordinances have been associated with reduced acute myocardial infarction rates, but nearly all studies lack patient-level data. OBJECTIVE We determined whether a smoking ordinance was associated with a reduction in hospitalizations for acute myocardial infarction, irrespective of smoking status and infarct presentation (ST elevation vs. non-ST elevation). METHODS Detailed chart abstraction of biomarkers to confirm first acute myocardial infarction events was performed from the single community hospital serving Greeley, Colorado and adjacent zip codes, 17 months before and 31 months after implementing a public smoking ordinance. Poisson regression analysis, adjusted for population growth, was used to assess changes in mean incidence rates. RESULTS A total of 706 hospitalizations were identified from July 2002 through June 2006: 482 among Greeley city residents and 224 within adjacent zip code areas. A postordinance reduction in hospitalizations was observed in Greeley (relative risk [RR] 0.73; 95% confidence interval [CI], 0.59-0.90). A smaller, nonsignificant decrease was noted in the area immediately surrounding Greeley (RR 0.83; 95% CI, 0.61-1.14). However, the comparison of relative risk reductions between Greeley and the surrounding area was not significant (P=.48). The reduction in Greeley was more pronounced among smokers (RR 0.44; 95% CI, 0.29-0.65) than nonsmokers (RR 0.86; 95% CI, 0.67-1.09) and did not differ by acute myocardial infarction presentation (P=.38). CONCLUSIONS A smoking ordinance was associated with a decrease in acute myocardial infarction hospitalizations of a magnitude similar to previous reports, but could not be distinguished from the adjacent geographic area. Reductions were greatest among smokers, despite previous studies suggesting that benefits accrue primarily among nonsmokers. Smoke-free policy may therefore exert a beneficial effect among smokers, who are disproportionately exposed to direct and sidestream smoke.

Abstract
INTRODUCTION Secondhand smoke is a risk factor for coronary heart disease. Laws and regulations prohibiting smoking in public areas and workplaces can reduce rates of acute myocardial infarction. Our objective was to describe hospital admission rates for acute coronary events, based on smoking status, diabetes status, and sex, in the presence of a long-standing (2000-2008) county clean indoor air regulation (CIAR). We also examined the effect of making restaurants completely smoke-free. METHODS We obtained hospital admission data for acute coronary syndrome (ACS) and acute myocardial infarction from all acute care hospitals serving Kanawha County, West Virginia, for 2000 through 2008. A CIAR was enacted in 1995 and revised in 2000 and 2003. We performed descriptive analyses on hospital admission rates of ACS over time and present these data by sex, age group, smoking status, and medical history of diabetes. RESULTS The incidence of hospital admissions for ACS consistently declined during the period studied. This change was most pronounced among nonsmokers, people without diabetes, and women, compared with their respective counterparts. Similar benefits occurred for male smokers when the CIAR was revised to make restaurants completely smoke-free in 2004. CONCLUSION In the presence of a CIAR, a consistent decline in incidence of hospital admissions for ACS can be demonstrated. However, the benefits derived may be disproportionately affected by smoking status, diabetes status, and sex.

Abstract
AIMS To study the impact of implementing smoke-free workplace and hospitality industry legislation on smoking behaviour. DESIGN, SETTING AND PARTICIPANTS A cross-sectional population survey from 2001 to 2008 (n ≈ 18,000 per year) was used to assess trends and seasonal patterns in smoking and quitting, and to examine whether changes could be observed after the workplace smoking ban in the Netherlands in 2004 and the hospitality industry ban in 2008. MEASUREMENTS Outcome measures were smoking prevalence, quit attempts and successful quit attempts. Interactions with educational level (socio-economic status) and bar visiting (exposure to the hospitality industry ban) were tested. FINDINGS The workplace ban was followed by a decrease in smoking prevalence (OR = 0.91, P < 0.001), but the hospitality industry ban was not (OR = 0.96, P = 0.127). Both bans, especially the workplace ban, were followed by an increase in quit attempts and successful quit attempts: workplace ban, OR = 1.31, P < 0.001; OR = 1.49, P < 0.001; hospitality industry ban, OR = 1.13, P = 0.013; OR = 1.44, P < 0.001. The workplace ban had a larger effect on successful quitting among higher-educated (OR = 0.35, P < 0.001) than on lower-educated respondents (OR = 0.74, P = 0.052). The hospitality industry ban had a larger effect on quit attempts among frequent bar visitors (OR = 1.48, P = 0.003) than on non-bar visitors (OR = 0.71, P = 0.014). CONCLUSIONS A workplace smoking ban in the Netherlands was followed by more changes in smoking and quitting than a hospitality industry ban. The hospitality industry ban only appeared to have an impact on quit attempts, and not on smoking prevalence.

Abstract
OBJECTIVES We examined the impact of Arizona's May 2007 comprehensive statewide smoking ban on hospital admissions for diagnoses for which there is evidence of a causal relationship with secondhand smoke (SHS) exposure (acute myocardial infarction [AMI], angina, stroke, and asthma). METHODS We compared monthly hospital admissions from January 2004 through May 2008 for these primary diagnoses and 4 diagnoses not associated with SHS (appendicitis, kidney stones, acute cholecystitis, and ulcers) for Arizona counties with preexisting county or municipal smoking bans and counties with no previous bans. We attributed reductions in admissions to the statewide ban if they occurred only in diagnoses associated with SHS and if they were larger in counties with no previous bans. We analyzed the data with Poisson regressions, controlling for seasonality and admissions trends. We also estimated cost savings. RESULTS Statistically significant reductions in hospital admissions were seen for AMI, angina, stroke, and asthma in counties with no previous bans over what was seen in counties with previous bans. No ban variable coefficients were statistically significant for diagnoses not associated with SHS. CONCLUSIONS Arizona's statewide smoking ban decreased hospital admissions for AMI, stroke, asthma, and angina.

Abstract
BACKGROUND Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and smoking behaviour of those populations they affect. OBJECTIVES To assess the extent to which legislation-based smoking bans or restrictions reduce exposure to SHS, help people who smoke to reduce tobacco consumption or lower smoking prevalence and affect the health of those in areas which have a ban or restriction in place. SEARCH STRATEGY We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL, Conference Paper Index, and reference lists and bibliographies of included studies. We also checked websites of various organisations. Date of most recent search; July 1st 2009. SELECTION CRITERIA We considered studies that reported legislative smoking bans and restrictions affecting populations. The minimum standard was having a ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. We included randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before and after studies, interrupted-time series as defined by the Cochrane Effective Practice and Organization of Care Group, and uncontrolled pre- and post-ban data. DATA COLLECTION AND ANALYSIS Characteristics and content of the interventions, participants, outcomes and methods of the included studies were extracted by one author and checked by a second. Because of heterogeneity in the design and content of the studies, we did not attempt a meta-analysis. We evaluated the studies using qualitative narrative synthesis. MAIN RESULTS There were 50 studies included in this review. Thirty-one studies reported exposure to secondhand smoke (SHS) with 19 studies measuring it using biomarkers. There was consistent evidence that smoking bans reduced exposure to SHS in workplaces, restaurants, pubs and in public places. There was a greater reduction in exposure to SHS in hospitality workers compared to the general population. We failed to detect any difference in self-reported exposure to SHS in cars. There was no change in either the prevalence or duration of reported exposure to SHS in the home as a result of implementing legislative bans. Twenty-three studies reported measures of active smoking, often as a co-variable rather than an end-point in itself, with no consistent evidence of a reduction in smoking prevalence attributable to the ban. Total tobacco consumption was reduced in studies where prevalence declined. Twenty-five studies reported health indicators as an outcome. Self-reported respiratory and sensory symptoms were measured in 12 studies, with lung function measured in five of them. There was consistent evidence of a reduction in hospital admissions for cardiac events as well as an improvement in some health indicators after the ban. AUTHORS' CONCLUSIONS Introduction of a legislative smoking ban does lead to a reduction in exposure to passive smoking. Hospitality workers experienced a greater reduction in exposure to SHS after implementing the ban compared to the general population. There is limited evidence about the impact on active smoking but the trend is downwards. There is some evidence of an improvement in health outcomes. The strongest evidence is the reduction seen in admissions for acute coronary syndrome. There is an increase in support for and compliance with smoking bans after the legislation.
