A prospective investigation of the impact of smoking bans on tobacco cessation and relapse

Smokefree policies to reduce tobacco use. A systematic review

In 2001, a systematic review for the Guide to Community Preventive Services identified strong evidence of effectiveness of smoking bans and restrictions in reducing exposure to environmental (secondhand) tobacco smoke. As follow-up to that earlier review, the focus here was on the evidence on effectiveness of smokefree policies in reducing tobacco use. Smokefree policies implemented by worksites or communities prohibit smoking in workplaces and designated public areas. The conceptual approach was modified for this review; an updated search for evidence was conducted; and the available evidence was evaluated. Published articles that met quality criteria and evaluated changes in tobacco-use prevalence or cessation were included in the review. A total of 57 studies were identified in the period 1976 through June 2005 that met criteria to be candidates for review; of these, 37 met study design and quality of execution criteria to qualify for final assessment. Twenty-one studies measured absolute differences in tobacco-use prevalence with a median effect of -3.4 percentage points (interquartile interval: -6.3 to -1.4 percentage points). Eleven studies measured differences in tobacco-use cessation among tobacco users exposed to a smokefree policy compared with tobacco users not exposed to a smokefree policy. The median absolute change was an increase in cessation of 6.4 percentage points (interquartile interval: 1.3 to 7.9 percentage points). The qualifying studies provided sufficient evidence that smokefree policies reduce tobacco use among workers when implemented in worksites or by communities. Finally, a systematic economic review identified four studies that, overall, demonstrated economic benefits from a smokefree workplace policy. Additional research is needed to more fully evaluate the total economic effects of these policies.

State adoption of 100% smoke-free acute non federal hospital campus policies

To assess the number and percentage of acute care hospitals in the U.S. that have adopted smoke-free hospital campus (SFHC) policies, researchers conducted an assessment from January 2008 to May 2008 of available data on SFHC policy adoption in each state. Slightly more than one third (34.4%) of acute care, non-Federal hospitals had adopted such policies, with wide variation of policy adoption between states.

Barriers and challenges of implementing tobacco control policies in hospitals: applying the institutional analysis and development framework to the Catalan Network of Smoke-Free Hospitals

This article analyzes tobacco control policies in hospitals based on the experience of the Catalan Network of Smoke-Free Hospitals, Spain. The objective is to understand through this case study how tobacco policies are designed and implemented in health care organizations. Because tobacco control is a public health issue, governmental, institutional, and professional involvement is necessary. This article identifies and examines the structure and relationships among the different actors involved in the tobacco control policies in health care organizations using Ostrom's Institutional Analysis and Development framework.This theory helps one understand the policy failures and rethink the future challenges. Critical issues should be reviewed to enhance implementation of smoke-free hospitals-such as assuring the compliance of nonsmoking areas and introducing compulsory tobacco cessation activities that are promoted and monitored by the public administration. The author suggests that relying primarily on an organization's interpretation of rules leads to irregular implementation.

Unintended consequences of smoke-free bar policies for low-SES women in three California counties

BACKGROUND

To amplify earlier studies of unintended consequences of public policies, this article illustrates both negative and positive unanticipated consequences of smoke-free workplace policies in California bars for women of low SES.

METHODS

The article relies on thematic analysis in 2008 of qualitative data gathered between 2001 and 2007 from three mixed-method studies of tobacco use in and around bars where indoor smoking is prohibited.

RESULTS

Unanticipated consequences primarily occurred when bars did comply with the law and smokers went outside the bar to smoke, particularly when smokers stood on the street outside the bar. Key negative consequences for women who smoked outside of bars included threats to their physical safety and their public image. For women living near bars, increased smoking on the street may have increased their exposure to secondhand smoke and disruptive noise. For some women, however, unanticipated negative consequences were identified with noncompliant bars. Smokers were conjectured to congregate in the smaller number of bars where smoking was still allowed, resulting in increased exposure to secondhand smoke for low-SES women working in these bars. A common positive unintended consequence of the tobacco control ordinance was increased social circulation and solidarity, as smokers gathered outside bars to smoke.

CONCLUSIONS

Smoke-free workplace laws in bars can have both negative and positive consequences for workers and smokers, and low-income women in particular.

Smoke-free medical facility campus legislation: support, resistance, difficulties and cost

Although medical facilities restrict smoking inside, many people continue to smoke outside, creating problems with second-hand smoke, litter, fire risks, and negative role modeling. In 2005, Arkansas passed legislation prohibiting smoking on medical facility campuses. Hospital administrators (N=113) were surveyed pre- and post-implementation. Administrators reported more support and less difficulty than anticipated. Actual cost was 10–50% of anticipated cost. Few negative effects and numerous positive effects on employee performance and retention were reported. The results may be of interest to hospital administrators and demonstrate that state legislation can play a positive role in facilitating broad health-related policy change.

Community readiness for local smoke-free policy change

PURPOSE

The purpose of this study was to use the Community Readiness Model to examine local smoke-free policy development.

DESIGN, SETTING, AND SUBJECTS

A descriptive, cross-sectional design was used to assess 64 Kentucky communities. Dimensions of readiness included a community's knowledge of the problem and existing voluntary smoke-free policies; leadership for policy development; resources for policy development; climate surrounding policy development; existing voluntary policy efforts; and political climate for policy development. Dimension scores were summed to identify one of six overall readiness stages: (1) unawareness; (2) vague awareness; (3) preplanning; (4) preparation; (5) initiation; and (6) endorsement.

ANALYSES

Correlations between dimensions and overall readiness scores were evaluated. One-way analysis of variance was used to evaluate regional trends, and multiple regression was used to assess the influence of sociodemographic/political variables on policy readiness.

RESULTS

The knowledge dimension rated highest, and community climate rated lowest. Most communities were in the lower stages of readiness. No relationship was found between overall readiness and region (F [4,59] = 1.17; p > .05); nor were there regional differences among dimension scores. Smaller communities were less ready for local policy development than larger ones (adjusted R2 = .25; p = .003).

CONCLUSIONS

The Community Readiness Model is appropriate for understanding local policy development, and it provides advocates with information that may prove helpful in advancing smoke-free policy.

Over-the-counter nicotine replacement therapy: can its impact on smoking cessation be enhanced?

Nicotine replacement therapies (NRTs) are efficacious smoking-cessation aids. However, only minimal increases in smoking cessation followed NRTs being made available over-the-counter (OTC), which presumably made these treatments more readily available. To better understand why the United States did not experience improvements in smoking cessation following the OTC availability of NRTs, it is useful to review factors that determine NRT's impact on smoking cessation and how these factors played out with the introduction of OTC NRT. The authors contend that for NRTs to have a greater impact on public health, increases are needed in the number of individuals making a quit attempt, the proportion using NRTs in a quit attempt, and the effectiveness of each quit attempt. Even small increases in the impact of OTC NRTs could yield significant benefits in terms of morbidity and mortality. The remainder of this article provides examples of interventions designed to target each of the aforementioned factors individually as well as examples of interventions that link increased cessation attempts, increased NRT reach, and increased NRT efficacy in order to synergistically enhance the impact of OTC NRTs.

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 April 2008, MEDLINE (1966 - April 2008), EMBASE (1985 - Feb 2008) and PsycINFO (to March 2008). We searched abstracts from international conferences on tobacco and the bibliographies of identified studies and reviews for additional references.

SELECTION CRITERIA

We selected interventions conducted in the workplace to promote smoking cessation. We included only randomized and quasi-randomized controlled trials allocating individuals, workplaces or companies to intervention or control conditions.

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 another. 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

We include 51 studies covering 53 interventions in this updated review. We found 37 studies of workplace interventions aimed at individual workers, covering group therapy, individual counselling, self-help materials, nicotine replacement therapy and social support. 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. We also found 16 studies testing interventions applied to the workplace as a whole. There was a lack of evidence that comprehensive programmes reduced the prevalence of smoking. Incentive schemes increased attempts to stop smoking, though there was less evidence that they increased the rate of actual quitting.

AUTHORS' CONCLUSIONS

1. We found strong evidence that interventions directed towards individual smokers increase the likelihood of quitting smoking. These include individual and group counselling and pharmacological treatment to overcome nicotine addiction. All these interventions show similar effects whether offered in the workplace or elsewhere. Self-help interventions and social support are less effective. Although people taking up these interventions are more likely to stop, the absolute numbers who quit are low.2. There was limited evidence that participation in programmes can be increased by competitions and incentives organized by the employer.3. We failed to detect an effect of comprehensive programmes in reducing the prevalence of smoking.

Prevalence of smoking among bar workers prior to the Republic of Ireland smokefree workplace legislation

BACKGROUND

This study establishes baseline prevalence of smoking and cigarette consumption among Cork bar workers prior to the Republic of Ireland's (ROI) smokefree workplace legislation and compares gender- and age-specific smoking rates and estimates the adjusted odds of being a smoker for Cork bar workers relative to the general population.

METHODS

Cross-sectional random sample of bar workers in Cork city and cross-sectional random telephone survey of the general population were conducted prior to the smokefree legislation.

RESULTS

Self reported smoking prevalence among Cork bar workers (n = 129) was 54% (58% using cotinine-validated measures), with particularly high rates in women (70%) and 18-28 years old (72%). Within the ROI (n = 1,240) sub-sample rates were substantially lower at 28%. Bar workers were twice as likely to be smokers as the general population sub-sample (OR = 2.15).

CONCLUSIONS

Cork bar workers constitute an occupational group with an extremely high smoking prevalence.

Characteristics of smokers accessing the Puerto Rico Quitline

BACKGROUND

In 2004, the Puerto Rico Department of Health implemented the Puerto Rico Quitline (PRQ), a proactive, telephone-based smoking cessation counseling program. This study examines the demographic and smoking-related characteristics of the individuals served by the PRQ.

METHODS

Analyses included PRQ participants registered from December 2004-December 2005. PRQ call rates and rate ratios (RR) were calculated overall, among smokers, and stratified by relevant covariates. Associations between sex and relevant characteristics of PRQ participants were compared using regression models.

RESULTS

Call rates per 100,000 smokers in PR were lower among men than women (RR = 0.50, 95% CI = 0.44-0.56), and higher among all age groups > or = 25 years of age as compared to those aged 15-24 years (RRs = 4.34-8.14) and among smokers living in the San Juan metropolitan area relative to smokers residing outside the metropolitan area (RR = 1.45, 95% CI = 1.29-1.63). Mass media was the most common way in which participants learned about the PRQ (> 70%), with only 2-3% of callers reporting a physician's referral as the source of their information about the PRQ. With respect to reasons for quitting, men were less likely than women to report concern about a child's health (OR = 0.62, 95% CI = 0.46-0.84) and cigarette odor (OR = 0.64, 95% CI = 0.41-0.99). Meanwhile, men were more likely (OR = 1.39, 95% CI = 1.01-1.91) to report the influence of other smokers as a barrier during quitting.

CONCLUSIONS

PRQ promotion and outreach efforts should target populations underserved by the PRQ including male, young adult, and non-metropolitan area smokers. Initiatives that link the PRQ with primary care providers in promoting smoking cessation should be encouraged.

An examination of the relationship between adolescents' initial smoking experience and their exposure to peer and family member smoking

Sensitivity to the initial smoking experience, upon initial smoking experimentation, is associated with youth smoking. We determined the association between exposure to smoking from peers and family members on the symptoms of the initial smoking experience of adolescents. Data from a survey of 3280 high school students in the British Columbia, Canada were obtained; including information on demographics, tobacco use history, symptoms of initial smoking experience, and the smoking behaviours of peers and family member's (from which an 'exposure to smoking from peers and family members' variable was created). In multivariate logistic regression models, individuals with higher scores on the 'exposure to smoking from peers and family members' variable were more likely to report positive symptoms of initial smoking experience, even after controlling for confounding variables. Higher scores on the 'exposure to smoking from peers and family members' variable was associated with increased 'initial smoking experience' scores. Initial smoking experience scores (i.e. total number of reported initial symptoms) weakly mediated the relationship between exposure to smoking from peers and family members and current smoking. The present findings suggest that exposure to smoking from peers and family members may be an important factor to consider in understanding youths initial smoking experiences.

Smoke-free laws and adult smoking prevalence

OBJECTIVE

To evaluate whether the adult smoking rate changed in Lexington-Fayette County, Kentucky, following the enactment of a smoke-free public places ordinance.

METHODS

Behavioral Risk Factor Surveillance System (BRFSS) data from 2001-2005 were used to test whether smoking rates changed in Fayette County from the pre- to post-law period, relative to the change in 30 Kentucky counties with similar demographics. The sample consisted of 10,413 BRFSS respondents: 7139 pre-law (40 months) and 3274 post-law (20 months).

RESULTS

There was a 31.9% decline in adult smoking in Fayette County (25.7% pre-law to 17.5% post-law). In the group of 30 Control counties, the rate was 28.4% pre-law and 27.6% post-law. Controlling for seasonality, time trend, age, gender, ethnicity, education, marital status, and income, there was a significant Time (pre- vs. post-law) by Group (Fayette vs. Controls) interaction. There were an estimated 16,500 fewer smokers in Fayette County during post-law compared to pre-law.

CONCLUSION

There was a significant effect of smoke-free legislation on adult smoking rates.

Changes in exposure to secondhand smoke among youth in Nebraska, 2002-2006

INTRODUCTION

Secondhand smoke is a major cause of morbidity and mortality. It has been associated with serious health problems in both children and adults. Efforts to reduce exposure to secondhand smoke in Nebraska have included programs to prevent tobacco use among young people and campaigns for smoke-free workplaces and homes. Despite these interventions, young people continue to be exposed to secondhand smoke at an unacceptably high rate. The objective of this study was to examine the extent to which Nebraska public middle and high school students were exposed to secondhand smoke in 2002 and 2006, to evaluate factors associated with this exposure, and to propose interventions.

METHODS

The Nebraska Youth Tobacco Survey was administered in 2002 and 2006 to a representative sample of students from public middle and high schools. All students who chose to participate completed an anonymous, self-administered survey that included questions on demographics, tobacco use, tobacco-related knowledge and attitudes, and exposure to secondhand smoke. Data were weighted to account for nonresponses at both student and school levels and to ensure generalizability of the estimates for public school students in Nebraska according to their grade, sex, and race/ethnicity. This study analyzed a subset of responses on secondhand smoke exposure, which was defined as being in a room or vehicle during the previous 7 days with someone who was smoking cigarettes.

RESULTS

Secondhand smoke exposure in a room, a vehicle, or both declined significantly among all students from 2002 (69.0%) to 2006 (61.3%). In both 2002 and 2006, students were significantly more likely to be exposed to secondhand smoke in a room than in a vehicle (64.4% vs 48.2% in 2002 and 56.9% vs 40.2% in 2006). Among racial and ethnic groups, only white students experienced a significant decline in exposure from 2002 (70.0%) to 2006 (61.4%). Girls were significantly more likely to be exposed to secondhand smoke in 2006 than were boys, and only boys experienced a significant overall decline in exposure from 2002 (69.3%) to 2006 (57.7%). Smoking behaviors and attitudes continued to influence secondhand smoke exposure from 2002 to 2006, although students experienced significant declines whether they were smokers or nonsmokers, and whether they lived with a smoker or not. Those with close friends who smoked and those who did not perceive secondhand smoke as harmful, however, did not benefit.

CONCLUSION

These data indicate reductions in exposure to secondhand smoke among Nebraska's middle and high school students, but exposure remains a problem, particularly in rooms. Adoption of a comprehensive statewide smoke-free policy will contribute to significantly reduced exposure to secondhand smoke among young people in public places, but other measures to address exposure in the home and private vehicles are needed or should be strengthened. These include physician counseling based on behavioral change theory to encourage cessation and home-based no-smoking rules, in addition to interventions that target minorities, who are disproportionately affected by secondhand smoke exposure. Evaluation of existing measures, such as programs to prevent tobacco use among young people and campaigns to collect pledges for smoke-free homes, will be required to determine their effectiveness in reducing exposure to secondhand smoke among youth in Nebraska.

Exploring barriers to implementation of smoking policies: a qualitative study on health professionals from three county-level hospitals

OBJECTIVE

This study was to identify factors limiting the implementation of smoking policies in county-level hospitals.

METHODS

We conducted qualitative interviews (17 focus groups discussions and 6 one-to-one in depth interviews) involving 103 health professionals from three target county-level hospitals. A combination of purposive and convenience sampling was used to recruit subjects and gain a broad range of perspectives on issues emerging from ongoing data-analysis until data saturation occurred. The transcripts were analyzed for themes and key points.

RESULTS

The main themes that emerged suggested that both smokers and non-smokers viewed smoking very negatively. However, it was clear that, underlying this acceptance of the health risks of smoking, there was a wide range of beliefs. Most of the health professionals pointed out that, as smoking was legal, addictive, and influenced by social norms, currently it was almost unrealistic to expect all smokers to give up smoking or not to smoke in the hospitals. Furthermore, they were concerned about the potentially detrimental effects of providing counseling advice to all smokers on the interpersonal relationship among colleagues or between doctors and patients. In addition, low level of employee participation influenced the sustainable implementation of smoking policies.

CONCLUSIONS

Simply being aware of the health risks about smoking did not necessarily result in successful implementation of the smoking policies. Application of comprehensive intervention strategies such as implementing smoking policies in public places at the county level, creating supportive environments, promoting community participation, and conducting health education, may be more effective.

Barriers and challenges for tobacco control in a smoke-free hospital

The study aimed to identify the extent of smoking, compliance with tobacco restrictions, and attitudes toward smoking and tobacco control measures among the employees in a Comprehensive Cancer Center from 2001 to 2006 where a smoke-free policy was progressively introduced. Four cross-sectional surveys were conducted from 2001 to 2006. Survey items include smoking status, smoking history, environmental tobacco exposure, and agreement with tobacco initiatives. The prevalence of smoking has declined from 34.5% in 2001 to 30.6% in 2006. The decrease was present in all professional groups: Doctors from 20.0% in 2001 to 15.2% in 2006 and administrative clerks from 56.0% in 2001 to 37.0% in 2006 reduced the most. Among nurses, the prevalence of smoking was still high with a 2-point percent reduction (from 34.0% in 2004 to 32.6% in 2006). Other changes of the pattern of smoking were apparent: a reduction on the number of cigarettes smoked, decrease of daily smokers, and increase of smoking abstinence during the hospital duty. Compliance with smoke-free areas increased. We observed a very significant decrease of the perception of exposure to environmental tobacco exposure at work. The Smoke Free project helped to achieve a healthy work environment. Tailored smoking cessation programs should be designed to help healthcare professionals to stop smoking. In addition, healthcare professionals should play a key role in promoting a healthy smoke-free lifestyle.

Smoke-free spaces over time: a policy diffusion study of bylaw development in Alberta and Ontario, Canada

Policy diffusion is a process whereby political bodies 'learn' policy solutions to public health problems by imitating policy from similar jurisdictions. This suggests that diffusion is a critical element in the policy development process, and that its role must be recognised in any examination of policy development. Yet, to date, no systematic work on the diffusion of smoke-free spaces bylaws has been reported. We examined the diffusion of municipal smoke-free bylaws over a 30-year period in the provinces of Alberta and Ontario, Canada, to begin to address this gap and to determine whether spatial patterns could be identified to help explain the nature of policy development. Bylaw adoption and change were analysed within local, regional, and provincial contexts. Geographical models of hierarchical and expansion diffusion in conjunction with the diffusion of innovations framework conceptually guided the analyses. Study findings contribute to a broader understanding of how and why health policies diffuse across time and place. Policy development can be a powerful mechanism for creating environments that support healthy decisions; hence, an understanding of policy diffusion is critical for those interested in policy interventions aimed at improving population health in any jurisdiction.

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.

[Evaluation of the degree of implementation of tobacco control interventions in the Catalan Network of Smoke-Free Hospitals]

OBJECTIVES

To evaluate the degree of implementation of tobacco prevention and control interventions and to determine the prevalence of smoking in the Catalan Network of Smoke-Free Hospitals according to the stage of adhesion to the project.

METHOD

We performed an observational, descriptive, cross sectional study in 16 hospitals actively involved in the Catalan Network of Smoke-Free Hospitals (April 2005). Data were collected using the results of the self-audit, 9-item questionnaire of the European Network for Smoke Free Hospitals. To study tobacco consumption, we interviewed 3,896 employees. Data on sociodemographic characteristics, tobacco consumption, job category, tobacco control indicators, the project's stage of implementation, and adherence to the project were gathered.

RESULTS

The prevalence of smoking was 35%. The implementation stage among all the hospitals studied was 53.3%. The items with high implementation scores (above 70%) were commitment, communication, consumption control, environmental control, and follow-up. Higher scores in implemented activities were observed in hospitals that had passed from the registration phase (x- = 26.6; standard deviation [SD] = 16.7) to subsequent phases (x- = 59.7; SD = 14.1), with a statistically significant difference in the overall score (p = 0.05).

CONCLUSIONS

The prevalence of smoking in the Catalan Network of Smoke-Free Hospitals remains high. However, the prevalence was lower among professionals serving as role models (physicians and nurses) than among the general population. The project's implementation increased according to the time since enrollment in the network, especially in the first year.

Tobacco Policy Regression in Arizona Worksites

Purpose.

To learn how worksite tobacco policies in Arizona changed between 1998 and 2001.

Design.

Telephone survey panel design.

Setting.

Arizona.

Subjects.

Private workplaces with at least five employees (N = 1008).

Measures.

Workplace policies were rated as “smoke free” (no smoking by employees in any indoor areas or in company vehicles except for designated smoking areas enclosed by physical barriers and having separate ventilation systems), “partial” policies (restrictive tobacco policies that did not meet the “smoke-free” standard), or no tobacco policy.

Analysis.

Bivariate statistical tests included χ2 and analysis of variance. Logistic regression was performed to identify the variables that best predicted the workplaces that weakened or eliminated their policies.

Results.

Tobacco policy in Arizona worksites improved overall, but 10.8% of worksites had weakened or eliminated tobacco policies present at baseline. Among worksites that were smoke free at baseline, 15.5% were no longer smoke free at follow-up.

Conclusion.

Policy regression is a disturbing finding that should be further explored. Our findings suggest that efforts to promote workplace tobacco policies should not end when policies are in place.

The impact of a smoking ban on hospital admissions for coronary heart disease

OBJECTIVE

In March 2002, the city of Bowling Green, Ohio, implemented a clean indoor air ordinance banning smoking in workplaces and public places. This study evaluates the effect of this ordinance on hospital admissions for smoking-related diseases.

METHODS

A quasi-experimental design with interrupted time-series was used including a matched control city (Kent, Ohio) with no clean indoor air ordinance. Data on hospital admissions during the period of January 1999 to June 2005 were analyzed using Autoregressive Integrated Moving Average (ARIMA) models.

RESULTS

A reduction in admission rates for smoking-related diseases was achieved in Bowling Green compared to the control city. The largest reduction was for coronary heart disease, where rates were decreased significantly by 39% after 1 year and by 47% after 3 years following the implementation of the ordinance. ARIMA models revealed a statistically significant downward trend in monthly admission rates for coronary heart disease (Bowling Green, omega=-1.69, p=0.036 vs. Kent, omega=-1.14, p=0.183) and support the hypothesis that the ordinance had a significant impact on admission rates for coronary heart disease.

CONCLUSION

The findings of this study suggest that clean indoor air ordinances lead to a reduction in hospital admissions for coronary heart disease, thus reducing health care costs.

Tobacco control for anesthesiologists

Anesthesiologists daily witness the consequences of tobacco use, the most common preventable cause of death. Smoking-related diseases such as atherosclerosis and chronic obstructive pulmonary disease increase anesthetic risk, and even smokers without overt disease are at increased risk for morbidity such as pulmonary and wound-related complications. Evidence suggests that stopping smoking will reduce the frequency of these complications. Nicotine and the other constituents of cigarette smoke, such as carbon monoxide, have important physiologic effects that may affect perioperative management. In addition, it is now apparent that the scheduling of elective surgery represents an excellent opportunity for smokers to quit in the long term. This review serves as an introduction to tobacco control for anesthesiologists, first examining issues of importance to perioperative management. It then discusses how anesthesiologists and other perioperative physicians can help address tobacco use, both at an individual level with their patients, and by contributing to the implementation of effective public health strategies in their countries. Anesthesiologists can play a key role in helping their patients quit smoking. Effective tobacco control measures applied to surgical patients will not only improve immediate perioperative outcomes but also long-term health.

An ethnographic study of tobacco control in hospital settings

BACKGROUND

Tobacco control in hospital settings is characterised by a focus on protection strategies and an increasing expectation that health practitioners provide cessation support to patients. While practitioners claim to have positive attitudes toward supporting patient cessation efforts, missed opportunities are the practice norm.

OBJECTIVE

To study hospital workplace culture relevant to tobacco use and control as part of a mixed-methods research project that investigated hospital-based registered nurses' integration of cessation interventions.

DESIGN

The study was conducted at two hospitals situated in British Columbia, Canada. Data collection included 135 hours of field work including observations of ward activities and designated smoking areas, 85 unstructured conversations with nurses, and the collection of patient-care documents on 16 adult in-patient wards.

RESULTS

The findings demonstrate that protection strategies (for example, smoking restrictions) were relatively well integrated into organisational culture and practice activities but the same was not true for cessation strategies. An analysis of resources and documentation relevant to tobacco revealed an absence of support for addressing tobacco use and cessation. Nurses framed patients' tobacco use as a relational issue, a risk to patient safety, and a burden. Furthermore, conversations revealed that nurses tended to possess only a vague awareness of nicotine dependence.

CONCLUSION

Overcoming challenges to extending tobacco control within hospitals could be enhanced by emphasising the value of addressing patients' tobacco use, raising awareness of nicotine dependence, and improving the availability of resources to address addiction issues.

Advertising and obesity: a behavioral perspective

Concern over the levels of obesity observed in Western countries has grown as researchers forecast a rapid growth in the medical care that a progressively more obese population will require. As health workers deal with increased incidences of diabetes and other obesity-related disorders, policymakers have examined the factors contributing to this problem. In particular, advertising that promotes high fat and high sugar products to children has come under increasing scrutiny. Advertisers have rejected claims that advertising contributes to obesity by arguing that it cannot coerce people into purchasing a product, and does not affect primary demand. This reasoning overlooks the role advertising plays in reinforcing and normalising behavior, however, and it assumes that only direct causal links merit regulatory attention. Ehrenberg's "weak" theory suggests advertising will support unhealthy eating behaviors, while the wide range of sales promotions employed will prompt trial and reward continued consumption. This article presents an alternative analysis of how marketing contributes to obesity and uses behavior modification theory to analyse the "fast-food" industry's promotions. We also review the New Zealand government's response to obesity and suggest policy interventions that would foster healthier eating behaviors.

Effects of new smoking regulations in Italy

BACKGROUND

From 10 January 2005 the Italian government banned smoking in all indoor public places. We conducted a population-based survey to provide information on attitudes towards smoking regulation and to disentangle the impact of the smoking ban on tobacco consumption.

PATIENTS AND METHODS

We considered data from a survey on smoking, based on 3114 subjects aged 15 or over, representative of the general adult Italian population in terms of age, sex, geographic area and socioeconomic status.

RESULTS

Once smoke-free policies were introduced, support for them in the public opinion tended to increase. In Italy, smoke-free policies accounted for around 8% decrease in cigarette consumption in the short run. Moreover, tobacco bans were almost universally accepted, and the smoke-free legislation did not seem to unfavourably affect the business of restaurants or cafes.

CONCLUSIONS

The results of our study on the first extensive smoking ban in a large country show the advantages of smoke-free legislations, which may have major public health implications.

The effect of involuntary job loss on smoking intensity and relapse

AIMS

To assess the impact of involuntary job loss due to plant closure or layoff on relapse to smoking and smoking intensity among older workers. DESIGN, PARTICIPANTS, SAMPLE: Data come from the Health and Retirement Study, a nationally representative survey of older Americans aged 51-61 in 1991 followed every 2 years beginning in 1992. The 3052 participants who were working at the initial wave and had any history of smoking comprise the main sample.

METHODS

Primary outcomes are smoking relapse at wave 2 (1994) among baseline former smokers, and smoking quantity at wave 2 among baseline current smokers. As reported at the wave 2 follow-up, 6.8% of the sample experienced an involuntary job loss between waves 1 and 2.

FINDINGS

Older workers have over two times greater odds of relapse subsequent to involuntary job loss than those who did not. Further, those who were current smokers prior to displacement that did not obtain new employment were found to be smoking more cigarettes, on average, post-job loss.

CONCLUSIONS

The stress of job loss, along with other significant changes associated with leaving one's job, which would tend to increase cigarette consumption, must outweigh the financial hardship which would tend to reduce consumption. This highlights job loss as an important health risk factor for older smokers.

Shaping reduced smoking in smokers without cessation plans

Most smokers do not plan to quit in the next 6 months. The authors previously demonstrated that percentile schedules shape lower breath carbon monoxide (BCO) levels in smokers trying to quit (R. J. Lamb, A. R. Morral, K. C. Kirby, M. Y. Iguchi, & G. Galbicka, 2004). In that study, the authors set reinforcement criteria based on the 9 most recent samples. In this study, the authors examined whether a more responsive procedure using the 4 most recent samples is more effective in smokers not trying to quit. Following institution of the contingencies in both groups, BCO levels were substantially reduced, and readiness to quit and cessation self-efficacy increased. However, more individuals in the 4-sample window group achieved a BCO level below 4 ppm, indicating recent abstinence. These individuals did so more rapidly and for a greater number of visits.

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.

Strength of clean indoor air laws and smoking related outcomes in the USA

OBJECTIVES

Environmental tobacco smoke (ETS) is often encountered in the workplace. There have been efforts to apply and enforce state laws limiting workplace smoking. There has been little study of the relative effectiveness of state and/or local laws in affecting both rates of workplace ETS exposure and adult smoking rates. This study investigates these hypotheses, as well as the effect of these laws on youth smoking.

DESIGN

This is a secondary data analysis using sources including the Current Population Survey (CPS), Behavioral Risk Factor Surveillance System (BRFSS), Youth Risk Behavior Survey (YRBS), and the National Household Survey of Drug Abuse (NHSDA) between the years of 1996 and 1999. Linear regression models were used to investigate the effect of a state's clean indoor air (CIA) law (using a measure of extensiveness) on the overall amount of people who reported working in a smoke-free environment, youth smoking rates and adult smoking rates.

RESULTS

The extensiveness of a state's CIA law was found to be a reliable predictor of the percentage of indoor workers who report a smoke-free work environment and the rates of youth smoking. State CIA laws were not conclusively associated with adult smoking rates.

CONCLUSIONS

The extensiveness of a state's CIA law is strongly associated with a higher percentage of indoor workers reporting a smoke-free work environment. This study did not reveal a similar association between local laws and smoke-free work environments. Youth smoking rates, shown to be related to state CIA laws, may be further affected with more stringent CIA policy.

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.

The economics of smoking and cardiovascular disease

The direct medical cost of cardiovascular and circulatory diseases was $151 billion in 1995, approximately 17% of all direct medical care costs in the United States. Incidence and prevalence based estimates indicate that smoking is a major contributing factor for cardiovascular disease and associated costs. Statewide smoking control programs and workplace and public area smoking bans are effective in reducing smoking prevalence. Smoking cessation therapies are very cost-effective interventions for the prevention of cardiovascular disease. Incidence based estimates indicate that smoking cessation control expenditures in the United States have been a cost effective method for reducing the direct medical costs of cardiovascular disease in the past, and may be cost saving in the future. The expected cost of producing an additional ex-smoker has been estimated to be approximately $1,000 to $1,500. Most or all of this cost can be recovered in the short run from savings in avoided heart attacks and strokes alone in healthy quitters. Observational studies of the direct medical costs following cessation in those observed to quit show a reduction utilization, but which may occur only after a lag of three to five years.

Hospital- and clinic-based smoking cessation interventions for smokers with cardiovascular disease

Cigarette smoking is the leading preventable cause of death in the United States and a major risk factor for cardiovascular disease (CVD). Large observational epidemiologic studies conducted in diverse populations have demonstrated a strong association between smoking and CVD morbidity and mortality. Observational epidemiologic studies have also demonstrated a substantial benefit of smoking cessation on cardiovascular morbidity and mortality. Smoking cessation after myocardial infarction reduces subsequent cardiovascular mortality by nearly 50%. Therefore, the use of effective strategies to reduce the prevalence of tobacco use is a high priority for both the primary and secondary prevention of CVD. Effective smoking cessation interventions have been identified in randomized controlled trials in the general population of smokers. These methods, which include behavioral counseling and pharmacotherapy, are incorporated into clinical practice guidelines for physicians in the United States and Great Britain. A smaller but still substantial body of evidence demonstrates the efficacy of these interventions in hospital- and clinic-based settings for smokers with CVD. This evidence is sufficient to support the routine implementation of these smoking cessation methods in inpatient and outpatient settings for smokers with CVD.

Effects of smoking restrictions in the workplace

The health hazards caused by exposure to environmental tobacco smoke (ETS) are well established. Workplace exposure to ETS is strongly influenced by the types of workplace and smoking policy-total bans on smoking have become common in many countries. Blue-collar and service workers are more likely than other types of workers to be exposed to ETS in the workplace. Smokers who are employed in workplaces with smoking bans are likely to consume fewer cigarettes per day, are more likely to be considering quitting, and quit at an increased rate compared with smokers employed in workplaces with no or weaker policies. Despite substantial progress in protecting workers from ETS, additional efforts are needed in areas that include attention to exposure among blue-collar and service workers; policies in workplaces with a limited number of employees; and studies of enforcement, effects on smoking cessation in multiple settings, and cost-effectiveness.

Effect of smoke-free workplaces on smoking behaviour: systematic review

OBJECTIVE

To quantify the effects of smoke-free workplaces on smoking in employees and compare these effects to those achieved through tax increases.

DESIGN

Systematic review with a random effects meta-analysis.

STUDY SELECTION

26 studies on the effects of smoke-free workplaces.

SETTING

Workplaces in the United States, Australia, Canada, and Germany.

PARTICIPANTS

Employees in unrestricted and totally smoke-free workplaces.

MAIN OUTCOME MEASURES

Daily cigarette consumption (per smoker and per employee) and smoking prevalence.

RESULTS

Totally smoke-free workplaces are associated with reductions in prevalence of smoking of 3.8% (95% confidence interval 2.8% to 4.7%) and 3.1 (2.4 to 3.8) fewer cigarettes smoked per day per continuing smoker. Combination of the effects of reduced prevalence and lower consumption per continuing smoker yields a mean reduction of 1.3 cigarettes per day per employee, which corresponds to a relative reduction of 29%. To achieve similar reductions the tax on a pack of cigarettes would have to increase from $0.76 to $3.05 (0.78 euro to 3.14 euro) in the United States and from 3.44 pounds sterling to 6.59 pounds sterling (5.32 euro to 10.20 euro) in the United Kingdom. If all workplaces became smoke-free, consumption per capita in the entire population would drop by 4.5% in the United States and 7.6% in the United Kingdom, costing the tobacco industry $1.7 billion and 310 million pounds sterling annually in lost sales. To achieve similar reductions tax per pack would have to increase to $1.11 and 4.26 pounds sterling.

CONCLUSIONS

Smoke-free workplaces not only protect non-smokers from the dangers of passive smoking, they also encourage smokers to quit or to reduce consumption.
