Effects of workplace smoking bans on cigarette consumption

[Uso de cigarros electrónicos en los espacios libres de humo y vapeo: una revisión sistemática.]

OBJECTIVE

The effect of smoke-free spaces on the use of electronic cigarettes has not been empirically demonstrated. The objective of this systematic review was to evaluate the influence of smoke-free and vape policies on the use of electronic cigarettes in young adults and adults.

METHODS

A systematic review was carried out according to PRISMA criteria in the Web of Science, PubMed and SCOPUS databases. Keywords used were: Electronic Nicotine Delivery Systems, Smoke-Free Policy, Young Adult and Adult. We included studies that analyzed the use of electronic cigarettes in smoke-free spaces in adults aged fifteen years and older. The search was conducted from January 2010 to March 2022. Risk of bias was analyzed with the Mixed Methods Assessment Tool.

RESULTS

The search identified 861 records. A total of 840 records were excluded because they did not meet the inclusion criteria. The final sample included ten studies on smoke-free spaces, six studies on vape-free spaces and five studies on smoke-free spaces and vape-free spaces. The main risk of bias in the studies was the sampling and measurements used. Most studies associate the use of electronic cigarettes and smoke-free spaces.

CONCLUSIONS

Studies suggest that the use of electronic cigarettes and smoke-free spaces and vape are associated. Studies with higher quality of evidence and simultaneous implementation of smoke-free and vape-free spaces are required.

Controlled trial of a workplace sales ban on sugar-sweetened beverages

OBJECTIVE

To examine the effectiveness of a workplace sugar-sweetened beverage (SSB) sales ban on reducing SSB consumption in employees, including those with cardiometabolic disease risk factors.

DESIGN

A controlled trial of ethnically diverse, full-time employees who consumed SSB heavily (sales ban n 315; control n 342). Outcomes included standardised measures of change in SSB consumption in the workplace (primary) and at home between baseline and 6 months post-sales ban.

SETTING

Sutter Health, a large non-profit healthcare delivery system in Northern California.

PARTICIPANTS

Full-time employees at Sutter Health screened for heavy SSB consumption.

RESULTS

Participants were 66·1 % non-White. On average, participants consumed 34·7 ounces (about 1 litre) of SSB per d, and the majority had an elevated baseline BMI (mean = 29·5). In adjusted regression analyses, those exposed to a workplace SSB sales ban for 6 months consumed 2·7 (95 % CI -4·9, -0·5) fewer ounces of SSB per d while at work, and 4·3 (95 % CI -8·4, -0·2) fewer total ounces per d, compared to controls. Sales ban participants with an elevated BMI or waist circumference had greater post-intervention reductions in workplace SSB consumption.

CONCLUSIONS

Workplace sales bans can reduce SSB consumption in ethnically diverse employee populations, including those at higher risk for cardiometabolic disease.

Dual and polytobacco use after a period of enforced tobacco cessation

The current study aimed to assess single product, dual, and polytobacco use in a young adult military population and how an enforced tobacco ban during training impacts these behaviors. Participants were 810 U.S. Airmen who reported tobacco use as civilians. Participants completed baseline and one-year follow-up surveys about their tobacco use from 2016 to 2019. Each product used by a participant was assigned a score based on their frequency of use, which were summed to create a total score. Change scores were calculated by determining the difference between baseline and follow-up frequency scores. Tobacco frequency score and the categorical change (e.g., increased, decreased) were compared between groups using t-tests and Chi-squared tests, respectively, adjusting for clustering effects by squadron and base. Among single product users, 44.58% quit using tobacco products, 47.1% remained single product users, and 8.32% became dual or polytobacco users. Among dual users, 39.1% quit, 43.1% became single product users, 14.2% remained dual users, and 3.7% became polytobacco users. Among polytobacco users, 29.9% quit, 43.4% became single product users, 17.9% became dual users, and 8.8% continued poly-tobacco use. Most participants reduced the number and frequency of tobacco products used. Implementing stringent policies that further restrict tobacco use may decrease tobacco product use or frequency of use.

Cost-Effectiveness Of A Workplace Ban On Sugar-Sweetened Beverage Sales: A Microsimulation Model

Sugar-sweetened beverages (SSBs) increase chronic disease risk. We estimated the impact on employee health and health care spending of banning SSB sales in California-based health care organizations. We used survey data from a large, multisite health care organization in California, sampling 2,276 employees three months before and twelve months after a workplace SSB sales ban was imposed. We incorporated the survey data into a simulation model to estimate chronic disease incidence and costs. We estimated that an SSB ban as effective as the one observed would save about $300,000 per 10,000 people over ten years among similar employers, as a result of averted health care and productivity spending—after both SSB sales losses and non-SSB beverage sales gains were accounted for. Sales bans would typically need to reduce SSB consumption by 2.2 ounces per person per day for lost revenue to be fully offset if there were no increase in non-SSB beverage sales.

Association of a Workplace Sales Ban on Sugar-Sweetened Beverages With Employee Consumption of Sugar-Sweetened Beverages and Health

IMPORTANCE

Reductions in sugar-sweetened beverage (SSB) intake can improve health, but are difficult for individuals to achieve on their own.

OBJECTIVES

To evaluate whether a workplace SSB sales ban was associated with SSB intake and cardiometabolic health among employees and whether a brief motivational intervention provides added benefits to the sales ban.

DESIGN, SETTING, AND PARTICIPANTS

This before-after study and additional randomized trial conducted from July 28, 2015, to October 16, 2016, at a Northern California university and hospital assessed SSB intake, anthropometrics, and cardiometabolic biomarkers among 214 full-time English-speaking employees who were frequent SSB consumers (≥360 mL [≥12 fl oz] per day) before and 10 months after implementation of an SSB sales ban in a large workplace, with half the employees randomized to receive a brief motivational intervention targeting SSB reduction.

INTERVENTIONS

The employer stopped selling SSBs in all workplace venues, and half the sample was randomized to receive a brief motivational intervention and the other half was a control group that did not receive the intervention. This intervention was modeled on standard brief motivational interventions for alcohol used in the workplace that promote health knowledge and goal setting.

MAIN OUTCOMES AND MEASURES

Outcomes included changes in SSB intake, Homeostatic Model Assessment of Insulin Resistance (HOMA-IR), and measures of abdominal adiposity. The primary associations tested were the correlation between changes in SSB intake and changes in HOMA-IR.

RESULTS

Among the 214 study participants, 124 (57.9%) were women, with a mean (SD) age of 41.2 (11.0) years and a baseline mean (SD) body mass index of 29.4 (6.5). They reported a mean daily intake of 1050 mL (35 fl oz) of SSBs at baseline and 540 mL (18 fl oz) at follow-up-a 510-mL (17-fl oz) (48.6%) decrease (P < .001). Reductions in SSB intake correlated with improvements in HOMA-IR (r = 0.16; P = .03). Those not randomized to receive the brief intervention reduced their SSB intake by a mean (SD) of 246.0 (84.0) mL (8.2 [2.8] fl oz), while those also receiving the brief intervention reduced SSB intake by 762.0 (84.0) mL (25.4 [2.8] fl oz). From baseline to follow-up, there were significant reductions in mean (SE) waist circumference (2.1 [2.8] cm; P < .001).

CONCLUSIONS AND RELEVANCE

This study's findings suggest that the workplace sales ban was associated with a reduction in SSB intake and a significant reduction in waist circumference among employees within 10 months. The randomized clinical trial portion of this study found that targeting those at high risk with a brief motivational intervention led to additional improvements. Workplace sales bans may offer a promising new private-sector strategy for reducing the health harms of SSB intake.

Workplace smoking restrictions and support for smoking cessation in the USA: state, region, and overall trends from 2010-11 to 2014-15

We discuss the most recent changes in smoking policies and support for smoking cessation offered to smokers at US workplaces. We used reports of employed adults (n = 112,008) regarding smoking restrictions and support for smoking cessation offered at their indoor workplaces from the 2010–11 and 2014–15 Tobacco Use Supplement-Current Population Survey. The percentage of adults who reported having workplace smoking restrictions was 94% in 2010–11 and 93% in 2014–15 (P = 0.001). There was a decrease in the Northeastern region (P < 0.001) and no significant changes in the other three US regions. The percentages decreased in Hawaii, New York, Oregon, Pennsylvania, and Tennessee and increased in Indiana, Nebraska, and Wyoming. The percentage of employees who reported having workplace support for smoking cessation increased from 24% to 29% (P < 0.001), which was uniform across all US regions but differed across the US states. The percentages decreased in Hawaii and increased in the majority of states. Analysis of smokers’ reports (versus all reports) resulted in lower percentages of workplaces with smoking restrictions and support for smoking cessation. It is essential to further enhance support for smoking cessation offered to smokers at US workplaces.

Smoke-Free Ordinances and Policies Protect Youth, but Ordinances Appear to Have Little Impact on Non-Combustible Tobacco Use

Smoke-free ordinances and policies protect youth from exposure to secondhand smoke (SHS) and cigarette use. This study investigated whether smoke-free ordinances also protect youth from the use of other tobacco products. We compared the prevalence of SHS exposure, cigarette smoking, cigar smoking, smokeless tobacco use, and e-cigarette use among high school students living in a municipality with or without a smoke-free ordinance and in homes with and without smoke-free policies. Data were analyzed using the 2017 Mississippi Youth Tobacco Survey (n = 1923). Smoke-free ordinances were found to be associated with lower prevalence of SHS exposure (41.9% vs. 51.5%), cigarette smoking (5.1% vs. 11.4%), and cigar smoking (7.2% vs. 10.9%). There were no differences in smokeless tobacco use (6.6% vs. 6.5%) or e-cigarette use (11.2% vs 12.1%). Smoke-free homes were associated with lower prevalence of SHS exposure (38.0% vs 74.6%), cigarette smoking (4.8% vs. 17.6%), cigar smoking (6.4% vs. 16.4%), smokeless tobacco use (4.9% vs. 13.2%), and e-cigarette use (9.6% vs. 19.5%), p < 0.05 for all comparisons. The results suggest that smoke-free ordinances and policies protect against exposure to tobacco smoke and use of combustible tobacco products, but smoke-free ordinances do not protect from smokeless tobacco and e-cigarette use. Tobacco-free, rather than smoke-free, ordinances might offer more protection.

Communicating the benefits of population health interventions: The health effects can be on par with those of medication

How can we communicate to the public that population level health interventions are effective at improving health? Perhaps the most familiar "currency" of effect is that which can be brought about via medication. Comparisons of effect sizes may be effective ways of communicating the benefits of population health interventions if they are seen and understood in the same way that medications are. We developed a series of comparisons to communicate benefits of population health interventions in terms of similar gains to be obtained from statins, metformin and antihypertensive medications for prevention of cardiovascular events, type 2 diabetes, obesity and hypertension. A purposive search identified evidence of population health intervention-related benefits. This evidence ranged from meta-analyses of RCTs to that from observational cohort studies. Population health interventions included implementation of national smoke free legislation, enhanced neighbourhood walkability, increased opportunities for active travel and protection of urban green space. In some cases, the benefits of population health interventions were found to be equivalent to, or even outweighed those of the medications to which they were compared. For example, RCT-based evidence suggested that exercise taken with a view of a green space was associated with 12 mmHg and 6 mmHg reductions in systolic and diastolic blood pressure, respectively, which was at least on par with the reductions associated with antihypertensive medications. Future work will test the effectiveness of these comparisons for increasing the familiarity, credibility and acceptability of population health interventions and, in particular, examine the importance of communicating putative mechanisms and potential co-benefits.

Exposure to workplace smoking bans and continuity of daily smoking patterns on workdays and weekends

INTRODUCTION

Individuals may compensate for workplace smoking bans by smoking more before or after work, or escaping bans to smoke, but no studies have conducted a detailed, quantitative analysis of such compensatory behaviors using real-time data.

METHODS

124 daily smokers documented smoking occasions over 3weeks using ecological momentary assessment (EMA), and provided information on real-world exposure to smoking restrictions and type of workplace smoking policy (full, partial, or no bans). Mixed modeling and generalized estimating equations assessed effects of time of day, weekday (vs weekend), and workplace policy on mean cigarettes per hour (CPH) and reports of changing location to smoke.

RESULTS

Individuals were most likely to change locations to smoke during business hours, regardless of work policy, and frequency of EMA reports of restrictions at work was associated with increased likelihood of changing locations to smoke (OR=1.11, 95% CI 1.05-1.16; p<0.0001). Workplace smoking policy, time block, and weekday/weekend interacted to predict CPH (p<0.01), such that individuals with partial work bans -but not those with full bans - smoked more at night (9pm - bed) on weekdays compared to weekends.

CONCLUSIONS

There was little evidence that full bans interfered with subjects' smoking during business hours across weekdays and weekends. Smokers largely compensate for exposure to workplace smoking bans by escaping restrictions during business hours. Better understanding the effects of smoking bans on smoking behavior may help to improve their effectiveness and yield insights into determinants of smoking in more restrictive environments.

Factors associated with secondhand smoke exposure in different settings: Results from the German Health Update (GEDA) 2012

BACKGROUND

The ubiquity of secondhand smoke (SHS) exposure at home or in private establishments, workplaces and public areas poses several challenges for the reduction of SHS exposure. This study aimed to describe the prevalence of SHS exposure in Germany and key factors associated with exposure. Results were also differentiated by place of exposure.

METHODS

A secondary data analysis based on the public use file of the German Health Update 2012 was conducted (n = 13,933). Only non-smokers were included in the analysis. In a multivariable logistic regression model the factors associated with SHS exposure were calculated. In addition, a further set of multivariable logistic regressions were calculated for factors associated with the place of SHS exposure (workplace, at home, bars/discotheques, restaurants, at the house of a friend).

RESULTS

More than a quarter of non-smoking study participants were exposed to SHS. The main area of exposure was the workplace (40.9 %). The multivariable logistic regression indicated young age as the most important factor associated with SHS exposure. The odds for SHS exposure was higher in men than in women. The likelihood of SHS exposure decreased with higher education. SHS exposure and the associated factors varied between different places of exposure.

CONCLUSIONS

Despite several actions to protect non-smokers which were implemented in Germany during the past years, SHS exposure still remains a relevant risk factor at a population level. According to the results of this study, particularly the workplace and other public places such as bars and discotheques have to be taken into account for the development of strategies to reduce SHS exposure.

Relationship of Smokefree Laws and Alcohol Use with Light and Intermittent Smoking and Quit Attempts among US Adults and Alcohol Users

Introduction

Light and intermittent smoking (LITS) has become increasingly common. Alcohol drinkers are more likely to smoke. We examined the association of smokefree law and bar law coverage and alcohol use with current smoking, LITS, and smoking quit attempts among US adults and alcohol drinkers.

Methods

Cross-sectional analyses among a population-based sample of US adults (n = 27,731) using restricted data from 2009 National Health Interview Survey and 2009 American Nonsmokers' Rights Foundation United States Tobacco Control Database. Multivariate logistic regression models examined the relationship of smokefree law coverage and drinking frequency (1) with current smoking among all adults; (2) with 4 LITS patterns among current smokers; and (3) with smoking quit attempts among 6 smoking subgroups. Same multivariate analyses were conducted but substituted smokefree bar law coverage for smokefree law coverage to investigate the association between smokefree bar laws and the outcomes. Finally we ran the above analyses among alcohol drinkers (n = 16,961) to examine the relationship of smokefree law (and bar law) coverage and binge drinking with the outcomes. All models controlled for demographics and average cigarette price per pack. The interactions of smokefree law (and bar law) coverage and drinking status was examined.

Results

Stronger smokefree law (and bar law) coverage was associated with lower odds of current smoking among all adults and among drinkers, and had the same effect across all drinking and binge drinking subgroups. Increased drinking frequency and binge drinking were related to higher odds of current smoking. Smokefree law (and bar law) coverage and drinking status were not associated with any LITS measures or smoking quit attempts.

Conclusions

Stronger smokefree laws and bar laws are associated with lower smoking rates across all drinking subgroups, which provides further support for these policies. More strict tobacco control measures might help reduce cigarette consumption and increase quit attempts.

Australian smokers' support for plain or standardised packs before and after implementation: findings from the ITC Four Country Survey

BACKGROUND

Plain packaging (PP) for tobacco products was fully implemented in Australia on 1 December 2012 along with larger graphic health warnings. Using longitudinal data from the Australian arm of the ITC Four Country Survey, we examined attitudes to the new packs before and after implementation, predictors of attitudinal change, and the relationship between support and quitting activity.

METHODS

A population-based cohort study design, with some cross-sectional analyses. Surveys of Australian smokers assessed attitudes to PP at four time points prior to implementation (from 2007 to 2012) and one post-implementation wave collected (early/mid-2013).

RESULTS

Trend analysis showed a slight rise in opposition to PP among smokers in the waves leading up to their implementation, but no change in support. Support for PP increased significantly after implementation (28.2% pre vs 49% post), such that post-PP more smokers were supportive than opposed (49% vs 34.7%). Multivariate analysis showed support either before or after implementation was predicted by belief in greater adverse health impacts of smoking, desire to quit and lower addiction. Among those not supportive before implementation, having no clear opinion about PP (versus being opposed) prior to the changes also predicted support post-implementation. Support for PP was prospectively associated with higher levels of quitting activity.

CONCLUSIONS

Since implementation of PP along with larger warnings, support among Australian smokers has increased. Support is related to lower addiction, stronger beliefs in the negative health impacts of smoking, and higher levels of quitting activity.

Population versus Clinical Perspectives on Smoking Behaviour

Effective mass-reach smoking-cessation interventions are required in order to accelerate the decline in the prevalence of smoking in Australia and other industrialised countries. Such large-scale interventions still rely, to a major extent, on theoretical principles derived from research with clinical or other opportunistic samples. Schachter (1982) argues that this type of research provides information which is unrepresentative of smokers in the general population. We compared a population-probability sample with a sample of smokers enrolling in a smoking-cessation program offered by a community health centre. The health centre sample was composed of predominantly female, older smokers who had higher smoking rates, had made more previous attempts to stop smoking, and tended to attribute their last relapse to irritability. We discuss some potential implications for research relevant to population-wide smoking control strategies.

Smoking ban policies and their influence on smoking behaviors among current California smokers: a population-based study

OBJECTIVE

To assess whether smoking ban policies are associated with smoking reduction and quit attempts among California smokers.

METHODS

Data were examined for 1718 current smokers from follow-up telephone interviews conducted in 2011 of persons previously identified as smokers in a representative sample of the adult population of California. Population weighted logistic regressions controlling for demographic and other variables were used to evaluate the association between smoking ban policies (home, work, and town) and changes in tobacco use (past year quit attempt or reduction in smoking rate).

RESULTS

Living in a home with a total ban was significantly associated with smoking reduction (adjusted odds ratio, AOR: 2.4, 95% CI: 1.4-4.2) and making a quit attempt (AOR: 2.3, 95% CI: 1.3-3.9) compared to living in a home with no home ban. Self-reported perception of an outdoor ban in one's city/town was associated with smoking reduction (AOR: 1.7, 95% CI: 1.02-2.7) and making a quit attempt (AOR: 1.8, 95% CI: 1.05-2.9).

CONCLUSION

These results indicate that smoking bans not only protect nonsmokers from the harms of secondhand smoke, but are also associated with smoking reduction and cessation.

Online comments on smoking bans in psychiatric hospitals units

OBJECTIVE

Individuals with mental health concerns are disproportionately affected by and suffer the negative consequences of tobacco use disorder, perhaps because smoking has historically been part of psychiatry's culture. In the early 1990s, psychiatric inpatient facilities were exempted from U.S. hospital smoking bans, in response to public outcry with national media attention. Almost 2 decades later, the current study characterizes online conversation about psychiatric hospital smoking bans. Previous commenting studies have demonstrated commenting's negativity, documenting the "nasty effect" wherein negative comments color perceptions of neutral articles. Thus, we focused particular attention on cited barriers to implementing health-positive smoke-free policies.

METHODS

We collected online comments (N = 261) responding to popular media articles on smoking bans in inpatient psychiatry between 2013 and 2014 and conducted an inductive and exploratory qualitative content analysis.

RESULTS

Verifying previous studies documenting the prevalence of negative commenting, of the comments explicitly supporting or refuting psychiatry smoking bans, there were over twice as many con comments (n = 44) than pro (n = 18). Many commenters argued for access to outdoor smoking areas and warned of patient agitation and risk posed to care workers. Identified content themes included psychiatric medication and negative side effects, broken mental health systems and institutions, denigration of the health risks of tobacco in the context of mental illness, typical pro-smoking arguments about "smokers' rights" and alternatives (including e-cigarettes), addiction, and stigma.

CONCLUSIONS

The current findings provide a platform to begin to understand how people talk about mental health issues and smoking. Our analysis also raised complex issues concerning forces that impact U.S. patients with serious mental illness but over which they have little control, including medication, the U.S. health system, stigma, perceptions that life with chronic serious mental illness is not worth living, and psychological and physical pain of coping with mental illness. In consideration of identified barriers raised in opposition to smoking bans in inpatient psychiatry, efforts should emphasize patient stakeholder involvement; patient, visitor, and staff protection from smoke exposure; the effectiveness of nicotine replacement for managing withdrawal; and the lack of evidence that cigarettes are therapeutic.

Modeling the Underlying Predicting Factors of Tobacco Smoking among Adolescents

BACKGROUND

With regard to the willing and starting tobacco smoking among young people in Iran. The aim of the study was to model the underlying factors in predicting the behavior of tobacco smoking among employed youth and students in Iran.

METHODS

In this analytical cross-sectional study, based on a random cluster sampling were recruited 850 high school students, employed and unemployed youth age ranged between 14 and 19 yr from Iran. The data of demographic and tobacco smoking related variables were acquired via a self-administered questionnaire. A series of univariate and multivariate logistic regressions were performed respectively for computing un-adjusted and adjusted Odds Ratios utilizing SPSS 17 software.

RESULTS

A number of 189 persons (25.6%) were smoker in the study and the mean smoking initiation age was 13.93 (SD= 2.21). In addition, smoker friend, peer persistence, leaving home, and smoking in one and six month ago were obtained as independent predictors of tobacco smoking.

CONCLUSIONS

The education programs on resistance skills against the persistence of the peers, improvement in health programs by governmental interference and policy should be implemented.

Variations in daily cigarette consumption on work days compared with nonwork days and associations with quitting: findings from the international tobacco control four-country survey

INTRODUCTION

We explore whether reported daily cigarette consumption differs between work days and nonwork days and whether variation in consumption between work days and nonwork days influences quitting and abstinence from smoking. We also explore whether effects are independent of measures of addiction and smoking restrictions at work and home.

METHODS

Data were from 5,732 respondents from the first five waves of the International Tobacco Control Four-Country Survey, occurring between 2002 and 2006. Respondents were current smokers employed outside the home. Variation in daily cigarette consumption on work days compared with nonwork days at one wave was used to predict the likelihood of making an attempt and the likelihood of maintaining a quit attempt for at least a month at the next wave. Generalized estimating equations were used to combine data for multiple waves.

RESULTS

Just under half reported smoking more on a nonwork day, a little over a third reported no difference, and around one fifth reported smoking more on a work day. Controlling for possible confounding factors, smoking more on a work day was associated with making quit attempts. Among people who made a quit attempt, variation in consumption did not consistently predict one month's abstinence, being positive in Australia, but negative in the United Kingdom.

CONCLUSION

Those who smoke more on work days try to quit more. Country differences for success may be related to the extent of bans on smoking, with those smoking more on work days more likely to succeed where bans in workplaces and public places were more prevalent, such as Australia at the time.

The role of worksite and home smoking bans in smoking cessation among U.S. employed adult female smokers

PURPOSE

Examine the association of work and home smoking bans with quitting behaviors among employed female smokers in the United States.

DESIGN

Secondary analyses using cross-sectional data from the 2006/2007 Tobacco Use Supplement to the Current Population Survey.

SUBJECTS

Nationally representative sample of 7610 U.S. employed female smokers, aged 18 to 64 years, who reported working indoors. Setting . N/A.

METHODS

Multivariate logistic regression analyses were conducted to examine the association of smoking ban policies (complete work and home bans, complete work ban only, complete home ban only, and no complete work or home ban) with intention to quit in the next 30 days, at least one quit attempt in the past year, and sustained abstinence of at least 3 months in the past year.

RESULTS

Twenty-nine percent of women reported complete work and home smoking bans. Smoking bans were not associated with intention to quit and were marginally associated with sustained abstinence. Regardless of intention to quit, women with complete work and home bans were significantly more likely than those without complete work and home bans to report quit attempts. Among women with no intention to quit, the odds of having a quit attempt were significantly higher among women who had a complete home ban only compared with women without complete work and home bans.

CONCLUSIONS

Efforts to promote quitting behaviors among employed female smokers may be facilitated by increasing rates of complete smoking bans at both work and home settings.

Forty years of secondhand smoke research: the gap between discovery and delivery

CONTEXT

Public health initiatives often focus on the discovery of risk factors associated with disease and death. Although this is an important step in protecting public health, recently the field has recognized that it is critical to move along the continuum from discovery of risk factors to delivery of interventions, and to improve the quality and speed of translating scientific discoveries into practice.

EVIDENCE ACQUISITION

To understand how public health problems move from discovery to delivery, citation network analysis was used to examine 1877 articles on secondhand smoke (SHS) published between 1965 and 2005. Data were collected and analyzed in 2006-2007.

EVIDENCE SYNTHESIS

Citation patterns showed discovery and delivery to be distinct areas of SHS research. There was little cross-citation between discovery and delivery research, including only nine citation connections between the main paths. A discovery article was 83.5% less likely to cite a delivery article than to cite another discovery article (OR=0.165 [95% CI=0.139, 0.197]), and a delivery article was 64.3% less likely (OR=0.357 [95% CI=0.330, 0.386]) to cite a discovery article than to cite another delivery article. Research summaries, such as Surgeon General reports, were cited frequently and appear to bridge the discovery-delivery gap.

CONCLUSIONS

There was a lack of cross-citation between discovery and delivery, even though they share the goal of understanding and reducing the impact of SHS. Reliance on research summaries, although they provide an important bridge between discovery and delivery, may slow the development of a field.

Study of the impact of laws regulating tobacco consumption on the prevalence of passive smoking in Spain

BACKGROUND

In 2005, the Spanish parliament passed the Spanish anti-smoking law. This legislation restricted tobacco smoking in public places, including recreation venues (bars and restaurants), but smoking was not completely prohibited in bars and restaurants. The law was enforced in January 2006. With the objective of analysing the impact that this law has had on the general Spanish population, the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) designed and implemented a survey of a representative sample of the general Spanish population on two separate occasions: in 2005 and in 2007 (12 months after the ban came into effect).

METHODS

Two epidemiological, observational and cross-sectional surveys were performed among a random and representative sample of the general Spanish population, using the Computer-Assisted Telephone Interview system.

RESULTS

In the first survey, a total of 6533 subjects were interviewed, of whom 3907 (59.8%) were non-smokers and in the second, a total of 3289 subjects were interviewed, of whom 2174 (65.9%) were non-smokers. The overall prevalence of exposure to environmental tobacco smoke (ETS) decreased from 49.5% in 2005 to 37.9% in 2007 (22% reduction). The greatest reduction in prevalence of ETS exposure was in workplaces (from 25.8% to 11%, a decrease of 58.8%). Smaller reductions occurred in the home (from 29.5% to 21.4%, a decrease of 27%) and in recreation venues (from 37.4% to 31.8%, a decrease of 8%).

CONCLUSIONS

Implementation of the smoking ban resulted in a significant decrease in exposure to ETS.

Implications of a public smoking ban

OBJECTIVES

Legislation to ban smoking in public places is currently a major area of interest across Canada. The main objectives of the study were to 1) determine the effect of the smoking ban on incidence of acute myocardial infarction, 2) determine if the new legislation altered population-based smoking prevalence, and 3) measure public support for the public smoking ban.

METHODS

The city of Saskatoon initiated a public smoking ban on July 1, 2004. We retrospectively reviewed all hospital discharges for acute MI from July 2000 to June 2005. We reviewed CCHS survey information on smoking prevalence for Saskatoon, Saskatchewan and Canada from 2003 to 2005. We prospectively contacted 1,255 Saskatoon residents by telephone to determine support for the public smoking ban.

RESULTS

The age-standardized incidence rate of acute MI fell from 176.1 (95% CI 165.3-186.8) cases per 100,000 population (July 1, 2000 to June 30, 2004) to 152.4 (95% CI 135.3-169.3) cases per 100,000 population (July 1, 2004 to June 30, 2005). Smoking prevalence in Saskatoon fell from 24.1% in 2003 (95% CI 20.4-27.7) to 18.2% in 2005 (95% CI 15.7-20.9) while smoking prevalence in Saskatchewan remained unchanged at 23.8% (95% CI 22.6-25.3) and Canada reduced from 22.9% (95% CI 22.5-23.3) to 21.3% (95% CI 20.8-21.8). Seventy-nine percent of Saskatoon residents believed the smoking ban was a good idea.

INTERPRETATION

The public smoking ban in Saskatoon, Canada, is associated with reduced incidence rates of acute MI, lower smoking prevalence and high levels of public support.

Smoking cessation rates in the United States: a comparison of young adult and older smokers

OBJECTIVES

We compared smoking quit rates by age in a nationally representative sample to determine differences in cessation rates among younger and older adults.

METHODS

We used data on recent dependent smokers aged 18 to 64 years from the 2003 Tobacco Use Supplement to the Current Population Survey (n=31625).

RESULTS

Young adults (aged 18-24 years) were more likely than were older adults (aged 35-64 years) to report having seriously tried to quit (84% vs 66%, P<.01) and to have quit for 6 months or longer (8.5% vs 5.0%, P<.01). Among those who seriously tried to quit, a smoke-free home was associated with quitting for 6 months or longer (odds ratio [OR]=4.13; 95% confidence interval [CI]=3.25, 5.26). Compared with older smokers, young adults were more likely to have smoke-free homes (43% vs 30%, P<.01), were less likely to use pharmaceutical aids (9.8% vs 23.7%, P<.01), and smoked fewer cigarettes per day (13.2% vs 17.4%, P<.01).

CONCLUSIONS

Young adults were more likely than were older adults to quit smoking successfully. This could be explained partly by young adults, more widespread interest in quitting, higher prevalence of smoke-free homes, and lower levels of dependence. High cessation rates among young adults may also reflect changing social norms.

Did the Tobacco Control Act Amendment in 1995 affect daily smoking in Finland? Effects of a restrictive workplace smoking policy

BACKGROUND

This study examined changes in adult daily smoking in 1981-2005 in Finland, in order to evaluate the impact of the 1995 Tobacco Control Act Amendment (TCAA) and accompanying measures on the proportion of daily smokers. The main focus of the TCAA was to prohibit smoking at workplaces (designated rooms excluded) in order to protect workers from environmental tobacco smoke.

METHODS

The study was based on data from annual postal surveys among 15- to 64-year-olds in 1981-2005 (average response rate 73%). The data set for this study comprised men and women aged 25-64 years (n = 73 471). Logistic models were used to test the effect of the 1995 TCAA across employment status while controlling for the effect of changes in the real price of tobacco and in gross domestic product per capita, and adjusting for age, education, secular trend and prevalence of ever-smokers in each birth cohort.

RESULTS

Controlling for confounding factors, the odds ratio (OR) for daily smoking after 1995 among employed men was 0.83 (95% CI 0.73-0.94) compared with the OR (1.0) for the period ending 1994. The corresponding figure for employed women was 0.78 (95% CI 0.68-0.91). The results can be interpreted as a positive effect of the 1995 TCAA on employees' daily smoking. Moreover, a similar decrease in daily smoking was not seen among those not targeted by the TCAA (including farmers, students, housewives, pensioners and the unemployed).

CONCLUSION

Smoking behaviour was and can be influenced by national tobacco policy measures.

Identifying health disparities across the tobacco continuum

AIMS

Few frameworks have addressed work-force diversity, inequities and inequalities as part of a comprehensive approach to eliminating tobacco-related health disparities. This paper summarizes the literature and describes the known disparities that exist along the tobacco disease continuum for minority racial and ethnic groups, those living in poverty, those with low education and blue-collar and service workers. The paper also discusses how work-force diversity, inequities in research practice and knowledge allocation and inequalities in access to and quality of health care are fundamental to addressing disparities in health.

METHODS

We examined the available scientific literature and existing public health reports to identify disparities across the tobacco disease continuum by minority racial/ethnic group, poverty status, education level and occupation.

FINDINGS

Results indicate that differences in risk indicators along the tobacco disease continuum do not explain fully tobacco-related cancer consequences among some minority racial/ethnic groups, particularly among the aggregate groups, blacks/African Americans and American Indians/Alaska Natives. The lack of within-race/ethnic group data and its interactions with socio-economic factors across the life-span contribute to the inconsistency we observe in the disease causal paradigm.

CONCLUSIONS

More comprehensive models are needed to understand the relationships among disparities, social context, diversity, inequalities and inequities. A systematic approach will also help researchers, practitioners, advocates and policy makers determine critical points for interventions, the types of studies and programs needed and integrative approaches needed to eliminate tobacco-related disparities.

Reductions in tobacco smoke pollution and increases in support for smoke-free public places following the implementation of comprehensive smoke-free workplace legislation in the Republic of Ireland: findings from the ITC Ireland/UK Survey

OBJECTIVE

To evaluate the psychosocial and behavioural impact of the first ever national level comprehensive workplace smoke-free law, implemented in Ireland in March 2004.

DESIGN

Quasi-experimental prospective cohort survey: parallel cohort telephone surveys of national representative samples of adult smokers in Ireland (n = 769) and the UK (n = 416), surveyed before the law (December 2003 to January 2004) and 8-9 months after the law (December 2004 to January 2005).

MAIN OUTCOME MEASURES

Respondents' reports of smoking in key public venues, support for total bans in those key venues, and behavioural changes due to the law.

RESULTS

The Irish law led to dramatic declines in reported smoking in all venues, including workplaces (62% to 14%), restaurants (85% to 3%), and bars/pubs (98% to 5%). Support for total bans among Irish smokers increased in all venues, including workplaces (43% to 67%), restaurants (45% to 77%), and bars/pubs (13% to 46%). Overall, 83% of Irish smokers reported that the smoke-free law was a "good" or "very good" thing. The proportion of Irish homes with smoking bans also increased. Approximately 46% of Irish smokers reported that the law had made them more likely to quit. Among Irish smokers who had quit at post-legislation, 80% reported that the law had helped them quit and 88% reported that the law helped them stay quit.

CONCLUSION

The Ireland smoke-free law stands as a positive example of how a population-level policy intervention can achieve its public health goals while achieving a high level of acceptance among smokers. These findings support initiatives in many countries toward implementing smoke-free legislation, particularly those who have ratified the Framework Convention on Tobacco Control, which calls for legislation to reduce tobacco smoke pollution.

Smoking, cessation and expenditure in low income Chinese: cross sectional survey

Background

This study was carried-out to explore smoking behaviour and smoking expenditure among low income workers in Eastern China to inform tobacco control policy.

Methods

A self-completion questionnaire was administered to 1958 urban workers, 1909 rural workers and 3248 migrant workers in Zhejiang Province, Eastern China in 2004.

Results

Overall 54% of the men and 1.8% of all women were current smokers (at least 1 cigarette per day). Smoking was least common in migrant men (51%), compared with 58% of urban workers and 64% rural inhabitants (P < 0.0001). Forty-nine percent of rural males smoke more than 10 cigarettes/day, and 22% over 20/day. The prevalence of smoking increased with age. Overall 9% of the males had successfully quit smoking. Reasons for quitting were to prevent future illness (58%), current illness (31%), family pressures (20%) and financial considerations (20%). Thirteen percent of current smokers had ever tried to quit (cessation for at least one week) while 22% intended to quit, with migrants most likely to intend to quit. Almost all (96%) were aware that smoking was harmful to health, though only 25% were aware of the dangers of passive smoking. A mean of 11% of personal monthly income is spent on smoking rising to a mean of 15.4% in rural smokers. This expenditure was found to have major opportunity costs, including in terms of healthcare access.

Conclusion

The prevalence of smoking and successful quitting suggest that smoking prevalence in low income groups in Eastern China may have peaked. Tobacco control should focus on support for quitters, on workplace/public place smoking restrictions and should develop specific programmes in rural areas. Health education messages should emphasise the opportunity costs of smoking and the dangers of passive smoking.

Psychiatric nurses' ethical stance on cigarette smoking by patients: determinants and dilemmas in their role in supporting cessation

It has been argued that psychiatric nurses are ideally placed to provide smoking cessation interventions to patients with mental illness. This assumes that psychiatric nurses actively support smoking cessation. The current paper articulates some of the reasons why this has not occurred, in particular, some of the ethical beliefs held by nurses that may prevent such activity. Such an assumption also discounts the evidence that confirms psychiatric nurses to have among the highest smoking rates in nursing and in the health professions in general. The role and impact of the institution are also considered. In-depth interviews with seven community and inpatient psychiatric nurses were thematically analysed. Extensive individual and group discussions were also held with inpatient nurses from open and locked psychiatric settings during participant observation of the settings. The findings suggest that psychiatric nurses can be more effective in the primary care role of supporting patients' smoking cessation if they receive adequate institutional support to do so.

Predictors of support for environmental tobacco smoke bans in state government

BACKGROUND

Environmental tobacco smoke (ETS) is a major threat to public health, associated with a number of serious diseases, and a leading cause of death. Previous research demonstrates that enactment of government policies mandating clean indoor air is effective in creating more smoke-free public places and decreasing the incidence of smoking. Both researchers and community activists have an interest in understanding the factors that predict support for the regulation of ETS.

METHODS

This study examined predictors of support for regulating ETS by surveying 684 city and county public officials in Colorado who were interviewed by phone and mail (response rate 61%).

RESULTS

Thirty-five percent of public officials reported that it is a "serious" or "very serious" problem that nonsmokers breathe in other people's cigarette smoke, 21% were "neutral," and 42% said that it was "not serious" or "not serious at all." Results indicated that support for policies to control ETS and promote clean indoor air is significantly more prevalent among public officials who: (1) believe that tobacco use is a serious problem in their community, (2) believe that breathing environmental tobacco smoke is a serious problem for nonsmokers, (3) believe that city and county government should get involved with people's decisions about smoking, (4) support smoking-cessation programs for public employees, and (5) have smoked less than 100 cigarettes during their lifetime.

CONCLUSIONS

Both the harms of ETS and legislation to create smoke-free environments remain controversial among local officials. Smoke-free advocates should support officials who believe that ETS is a problem and persuade officials on the harms of ETS and the need for government intervention.

Reducing Cigarette Smoking Among Working Adolescents: Results from the SMART Study

OBJECTIVE

The SMART Teens Against the Risks of Tobacco Study was designed to test the feasibility and efficacy of tobacco control intervention methods for employed teens.

METHODS

A randomized controlled pilot study tested the efficacy of a behavioral intervention delivered between September, 1999, and August, 2000. Baseline and final survey data were collected on 560 teens in four intervention and five control stores.

RESULTS

Although smoking prevalence decreased and intention to quit increased more among teens in the intervention stores compared to those in the control stores, the differences were not statistically significant.

CONCLUSIONS

The worksite holds promise as a possible venue for tobacco prevention and cessation interventions for youth although further research is needed to increase the efficacy of interventions for this setting.

Self-efficacy: A predictor for smoking cessation contemplators in Kuwaiti adults

The failure of most of the smoking cessation programs might be due to negligence of including self-efficacy as an imperative factor in changing many adverse behaviors such as smoking. This study investigates the role of self-efficacy as a predictor for smoking cessation contemplators and precontemplators in adult male Kuwaiti smoker employees. A sample of 657 Kuwaiti male smokers represented the target population. Factor analysis with varimax rotation to the self-efficacy 16-items scale revealed four essential factors-mood changes, relaxation, stress, and self-image-for smoking urge in the studied population. Contemplators had significant higher mean self-efficacy total scores and Factor IV (self-image) subtotal scores than precontemplators. Stepwise multivariate logistic binary regression analysis illustrated that self-efficacy is the first predictor for contemplating smoking cessation followed by monthly income. Self-efficacy as a cognitive determinant should be considered to mediate improvement in the smoking cessation programs.

Smoking bans in psychiatric inpatient settings? A review of the research

OBJECTIVE

This paper reviews the findings from 26 international studies that report on the effectiveness of smoking bans in inpatient psychiatric settings. The main aim is to identify which processes contribute to successful implementation of smoking bans and which processes create problems for implementation in these settings.

METHOD

After performing an electronic search of the literature, the studies were compared for methods used, subjects involved, type of setting, type of ban, measures and processes used and overall results. Total bans were distinguished from partial bans. All known studies of smoking bans in psychiatric inpatient units from 1988 to the present were included.

RESULTS

Staff generally anticipated more smoking-related problems than actually occurred. There was no increase in aggression, use of seclusion, discharge against medical advice or increased use of as-needed medication following the ban. Consistency, coordination and full administrative support for the ban were seen as essential to success, with problems occurring where this was not the case. Nicotine replacement therapy was widely used by patients as part of coping with bans. However, many patients continued to smoke post-admission indicating that bans were not necessarily effective in assisting people to quit in the longer term.

CONCLUSIONS

The introduction of smoking bans in psychiatric inpatient settings is possible but would need to be a clearly and carefully planned process involving all parties affected by the bans. Imposing bans in inpatient settings is seen as only part of a much larger strategy needed to overcome the high rates of smoking among mental health populations.

Smoking behaviour among young adults: beyond youth prevention

OBJECTIVE

There is a widespread assumption that smoking behaviour is largely established by the age of 18 years. As a result, smoking prevention has focused almost exclusively upon youth. However, recent trends suggest that young adulthood may be an important--and largely overlooked--period in the development of regular smoking behaviour. The current study sought to examine patterns of tobacco use among young adults (aged 18-29 years) and to address the implications for tobacco control policy.

DESIGN

Data are presented from the 2003 Canadian Tobacco Use Monitoring Survey, a national survey of smoking behaviour (n = 10,559, response rate 89%).

MAIN OUTCOME MEASURES

Measures of smoking behaviour, smoking initiation, susceptibility to smoking, and occupational status.

RESULTS

A total of 1.4 million or 28% of young adults in Canada currently smoke, the highest proportion among all age groups. The prevalence of daily smoking rose from 8% among youth to 22% among young adults, and approximately one fifth of smokers tried their first cigarette after the age of 18 years. Smoking behaviour among young adults was also distinct from older smokers: young adults were more likely to be occasional smokers and reported lower daily consumption. Finally, smoking prevalence and cessation rates varied substantially within subgroups of young adults, as characterised by occupational setting.

CONCLUSIONS

Dramatic increases in the proportion and intensity of smoking occurs after the age of 18 years. Smoking behaviour among young adults is distinct from both youth and older adults, and warrants immediate attention from the public health community.

A longitudinal assessment of the impact of smoke-free worksite policies on tobacco use

OBJECTIVES

In this cohort study, we assessed the impact of smoke-free work-site policies on smoking cessation behaviors.

METHODS

Smokers were tracked as part of the Community Intervention Trial for Smoking Cessation. Telephone surveys were administered to 1967 employed smokers in 1993 and 2001. Data were gathered on personal and demographic characteristics, tobacco use behaviors, and restrictiveness of worksite smoking policies.

RESULTS

People who worked in environments that changed to or maintained smoke-free policies between 1993 and 2001 were 1.9 times more likely (odds ratio [OR] = 1.92; 95% confidence interval [CI] = 1.11, 3.32) than people whose worksites did not do so to have stopped smoking by 2001. Continuing smokers decreased their average daily consumption by 2.57 cigarettes. People working in environments that had smoke-free policies in place in both 1993 and 2001 were 2.3 times more likely (OR=2.29; 95% CI=1.08, 4.45) than people not working in such environments to have quit by 2001, and continuing smokers reported a decline in average daily consumption of 3.85 cigarettes.

CONCLUSIONS

Smoke-free worksite policies help employees reduce their cigarette consumption and stop smoking.

Workplace interventions for smoking cessation

BACKGROUND

The workplace has potential as a setting through which large groups of people can be reached to encourage smoking cessation.

OBJECTIVES

To categorize workplace interventions for smoking cessation tested in controlled studies and to determine the extent to which they help workers to stop smoking or to reduce tobacco consumption.

SEARCH STRATEGY

We searched the Cochrane Tobacco Addiction Group Specialized Register in October 2004, MEDLINE (1966 - October 2004), EMBASE (1985 - October 2004) and PsycINFO (to October 2004). We searched abstracts from international conferences on tobacco and we checked the bibliographies of identified studies and reviews for additional references.

SELECTION CRITERIA

We categorized interventions into two groups: a) Interventions aimed at the individual to promote smoking cessation and b) interventions aimed at the workplace as a whole. We applied different inclusion criteria for the different types of study. For interventions aimed at helping individuals to stop smoking, we included only randomized controlled trials allocating individuals, workplaces or companies to intervention or control conditions. For studies of smoking restrictions and bans in the workplace, we also included controlled trials with baseline and post-intervention outcomes and interrupted times series studies.

DATA COLLECTION AND ANALYSIS

Information relating to the characteristics and content of all kinds of interventions, participants, outcomes and methods of the study was abstracted by one author and checked by two others. Because of heterogeneity in the design and content of the included studies, we did not attempt formal meta-analysis, and evaluated the studies using qualitative narrative synthesis.

MAIN RESULTS

Workplace interventions aimed at helping individuals to stop smoking included ten studies of group therapy, seven studies of individual counselling, nine studies of self-help materials and five studies of nicotine replacement therapy. The results were consistent with those found in other settings. Group programmes, individual counselling and nicotine replacement therapy increased cessation rates in comparison to no treatment or minimal intervention controls. Self-help materials were less effective.Workplace interventions aimed at the workforce as a whole included 14 studies of tobacco bans, two studies of social support, four studies of environmental support, five studies of incentives, and eight studies of comprehensive (multi-component) programmes. Tobacco bans decreased cigarette consumption during the working day but their effect on total consumption was less certain. We failed to detect an increase in quit rates from adding social and environmental support to these programmes. There was a lack of evidence that comprehensive programmes reduced the prevalence of smoking. Competitions and incentives increased attempts to stop smoking, though there was less evidence that they increased the rate of actual quitting.

AUTHORS' CONCLUSIONS

We found: 1. Strong evidence that interventions directed towards individual smokers increase the likelihood of quitting smoking. These include advice from a health professional, individual and group counselling and pharmacological treatment to overcome nicotine addiction. Self-help interventions are less effective. All these interventions are effective whether offered in the workplace or elsewhere. Although people taking up these interventions are more likely to stop, the absolute numbers who quit are low. 2. Limited evidence that participation in programmes can be increased by competitions and incentives organized by the employer. 3. Consistent evidence that workplace tobacco policies and bans can decrease cigarette consumption during the working day by smokers and exposure of non-smoking employees to environmental tobacco smoke at work, but conflicting evidence about whether they decrease prevalence of smoking or overall consumption of tobacco by smokers. 4. A lack of evidence that comprehensive approaches reduce the prevalence of smoking, despite the strong theoretical rationale for their use. 5. A lack of evidence about the cost-effectiveness of workplace programmes.

Adolescent and young adult tobacco prevention and cessation: current status and future directions

OBJECTIVE

To summarise the evidence on adolescent and young adult prevention and cessation, and provide future directions for research.

DATA SOURCES

Data were collected from published literature. Searches for adolescent prevention were conducted using PubMed, PsycInfo, and ERIC; and for cessation, PubMed, and two major reviews that span January 1978 to May 2002. PubMed, PsychInfo, and SCCI were searched for young adults from January 1990 to May 2002.

STUDY SELECTION

Data included smoking prevention studies published from January 1990 to May 2002 and conducted in the USA; all identified smoking cessation studies for adolescents. Young adult data were limited to initiation and cessation studies.

DATA EXTRACTION

Extraction of data was by consensus of the authors.

DATA SYNTHESIS

Results of the review are qualitative in nature using a consensus approach of the authors.

CONCLUSIONS

School based curricula alone have been generally ineffective in the long term in preventing adolescents from initiating tobacco use but are effective when combined with other approaches such as media and smoke-free policies. Prevention research should consider multiple approaches and the social conditions that influence the development of youth problem behaviours including tobacco use. Because youth smoking cessation has been understudied to date, scientifically rigorous adolescent smoking cessation studies need to be conducted with attention to high risk smokers and less than daily smokers. Tobacco prevention and cessation for young adults needs focused attention. Prevention and cessation programmes need to address other tobacco products in addition to cigarettes.

The feasibility of evaluating a tobacco control intervention for working youth

OBJECTIVES

To describe the feasibility of implementing evaluation methods for a worksite tobacco control intervention for teens. Indicators of feasibility included employment stability, response rates to multiple surveys, and self reported 30 day smoking.

DESIGN

Grocery stores that were part of a single chain were randomised to four intervention stores and five control stores as part of the SMART project, a phase II methods development study designed to reduce smoking among working adolescents.

SUBJECTS

Data on smoking in the last 30 days and employment patterns were collected from working teens aged 15-18 years at seven data points over the 12 month intervention period using cross sectional surveys.

RESULTS

Data on employment stability indicate that employee turnover rates averaged 21% over the seven administrations. Response rates for the seven surveys ranged from 43-77% and were slightly greater in the control stores than the interventions stores (71% v 59%, p = 0.06). Mean current smoking at the individual store level ranged from 9-32% and there was a negative correlation between smoking prevalence and response rate by survey and by store (-0.029, p = 0.03). Among smokers who completed at least two surveys, there were no significant differences between intervention and control store on changes in the frequency of smoking.

CONCLUSIONS

Evaluating a tobacco control intervention in the grocery store setting requires multiple survey assessments to monitor changes in smoking among adolescents. Strategies are needed to maintain high response rates and increase the number of multiple responses from eligible teens.

A "smoke-free" hospital in Israel--a possible mission

BACKGROUND

A revised antismoking law in Israel (August 2001) called for a complete ban of smoking in hospitals. An evaluation of a hospital process and short-term outcome of implementing such policy may guideline its sustainability.

METHODS

Two cross-sectional, random-sample surveys of employees 3 months before policy implementation, and 6-9 months post-implementation. The pre-implementation survey included 368 employees (90.4% response rate) and the post-implementation survey, 364 (92.8% response rate).

RESULTS

The 'smoke-free' policy significantly reduced smoking in the unauthorized areas. Before implementation, 63% of staff reported frequently observing smoking in the hospital, compared to 40% 6 months post-policy implementation (P < 0.001). Significantly more smokers reported leaving their workplace to smoke (17% pre- vs. 62% post-implementation, P < 0.0001). Sixty-five percent of smokers, in both surveys, agreed that "a smoke-free policy is unfair to smokers". Fewer nonsmokers subscribed to this belief: 42% pre- and 34% post-implementation. Smoker prevalence remained unchanged (19%).

CONCLUSIONS

Implementation of a "smoke-free" policy is an effective way to reduce smoking in the hospital environment. More effort is required, however, to help staff quit smoking altogether.

The effects of tobacco control policies on smoking rates: a tobacco control scorecard

This article reviews studies of the effect of tobacco control policies on smoking rates with the aim of providing guidance on the importance of different policies. Based on past studies, we estimate the magnitude of effects of major tobacco control policies, how their effects depend on the manner in which the policies are implemented, the relationship between the different policies, and the barriers to implementation. The most successful campaigns have implemented a combination of tobacco control policies. Of those policies, substantial evidence indicates that higher taxes and clean air laws can have a large impact on smoking rates. Evidence also indicates that media campaigns when implemented with other policies are important. Research on greater access to treatment and telephone support hotlines indicates a strong potential to increase quit rates and may be important in affecting heavier smokers. Direct evidence on the effects of advertising bans and health warnings is mixed, but these policies appear to be important in some of the countries that have had success in reducing smoking rates. School education programs and limits on retail sales are not likely to have much impact if implemented alone, but may be more important when combined with other policies.

Reducing occupation-based disparities related to tobacco: roles for occupational health and organized labor

BACKGROUND

Persistent and growing occupation-based disparities related to tobacco pose a serious public health challenge. Tobacco exacts a disproportionate toll on individuals employed in working class occupations, due to higher prevalence of smoking and exposure to secondhand smoke among these workers compared to others.

METHODS

We provide an overview of recent advances that may help to reduce these disparities, including research findings on a successful social contextual intervention model that integrates smoking cessation and occupational health and safety, and a new national effort to link labor unions and tobacco control organizations around their shared interest in reducing tobacco's threat to workers' health.

CONCLUSIONS

Implications of these efforts for future research and action are discussed.

Support for smoking restrictions in bars and gaming areas: review of Australian studies

OBJECTIVE

To document levels of public support in Australia for smoking restrictions in licensed premises, including trends over time, and to examine the potential effects of a ban on patronage.

METHOD

Systematic review of published and unpublished studies of community and staff attitudes towards smoking in bars, gaming areas and related venues were identified using Medline, Current Contents, PsycINFO and AUSTHealth prior to September 2002. State and Territory health departments, cancer organisations and branches of the National Heart Foundation were approached. Cross-sectional surveys reporting data on attitudes towards smoking restrictions and/or perceptions of effects on patronage were sought. Two reviewers assessed studies for inclusion. One extracted data using pre-coded categories with checking by the second.

RESULTS

Thirty-four community and seven staff surveys were synthesised qualitatively, with greater emphasis given to surveys using random selection. All surveys conducted since 1993, which included the separate smoking area response option, have demonstrated majority support for some form of smoking restriction on licensed premises. From 2000, surveys with the ban option alone report majority support for prohibiting smoking completely in bars (52-68%) and gaming areas (64-76%). Support increased significantly after the Sharp damages award. Customer preference data indicate banning smoking is most likely to have a neutral or positive effect on patronage.

CONCLUSIONS AND IMPLICATIONS

Support for a ban on smoking in licensed premises has increased by almost 20% in the past decade. State and Territory governments should introduce legislation banning smoking in all indoor drinking and gaming areas immediately.
