Effects of a restricted work-site smoking policy on employees who smoke

Society for Research on Nicotine and Tobacco as an Outgrowth of the 1988 Surgeon General's Report on Nicotine Addiction: Reflections of the Early Presidents

INTRODUCTION

The Society for Research on Nicotine and Tobacco began in the United States as a scientific organization "to stimulate the generation and dissemination of new knowledge concerning nicotine and tobacco in all its manifestations." Now in its 30th year, the Society is taking on new challenges in tobacco control, nicotine vaping, product regulation, and public policy.

AIMS AND METHODS

This Review describes the formative years of the Society from the perspective of researchers who were in leadership positions during that time, documenting how biobehavioral and clinical research in the first 10 years was a continuation of the scientific mission of the 1988 United States Surgeon General's Report on Nicotine Addiction and summarizing organizational innovations during each president's term of office.

CONCLUSIONS

The Society's promotion of scientific research served as a catalyst for funding, policy, and regulation, setting the stage for its influence and credibility.

IMPLICATIONS

This Commentary provides context and an overview of the scientific research and the organizational innovations that occurred during the early years of the Society for Research on Nicotine and Tobacco using publications and available documentation. The Society was able to thrive because biobehavioral research on nicotine addiction provided the scientific underpinnings for the tobacco control enterprise as a whole. The objective of this Commentary is to describe formative events in the Society's history based on the accomplishments of its early leaders.

Supporting a Culture of Health in the Workplace: A Review of Evidence-Based Elements

OBJECTIVE

To identify and evaluate the evidence base for culture of health elements.

DATA SOURCE

Multiple databases were systematically searched to identify research studies published between 1990 and 2015 on culture of health elements.

STUDY INCLUSION AND EXCLUSION CRITERIA

Researchers included studies based on the following criteria: (1) conducted in a worksite setting; (2) applied and evaluated 1 or more culture of health elements; and (3) reported 1 or more health or safety factors.

DATA EXTRACTION

Eleven researchers screened the identified studies with abstraction conducted by a primary and secondary reviewer. Of the 1023 articles identified, 10 research reviews and 95 standard studies were eligible and abstracted.

DATA SYNTHESIS

Data synthesis focused on research approach and design as well as culture of health elements evaluated.

RESULTS

The majority of published studies reviewed were identified as quantitative studies (62), whereas fewer were qualitative (27), research reviews (10), or other study approaches. Three of the most frequently studied culture of health elements were built environment (25), policies and procedures (28), and communications (27). Although all studies included a health or safety factor, not all reported a statistically significant outcome.

CONCLUSIONS

A considerable number of cross-sectional studies demonstrated significant and salient correlations between culture of health elements and the health and safety of employees, but more research is needed to examine causality.

Tobacco Use Prevention and Cessation Policies in Manufacturing Facilities in the Tobacco-Growing State of Kentucky

Purpose.

To assess workplace tobacco use prevention and cessation policies in manufacturing facilities and explore factors associated with tobacco policies and practices in the tobacco-growing state of Kentucky.

Design.

Cross-sectional, descriptive, correlational design.

Setting.

Telephone survey of Kentucky manufacturing facilities.

Subjects.

A total of 437 human resource managers (77% participation rate).

Measures.

Telephone interviews by trained local health department staff to assess indoor and outdoor smoking policies, sale of cigarettes on company property, and provision of cessation and prevention programs.

Results.

Nearly seven in 10 manufacturing facilities had a written smoking policy, but only 43% banned indoor smoking. About one-fourth of companies reimbursed for cessation treatment and/or provided cessation resources. Companies with unions were more likely than those without unions to provide cessation resources but were also more likely to allow indoor smoking. Although large companies had more than two and a half times the odds as small companies to have a written smoking policy, they were more likely to allow cigarette sales on company property.

Conclusion.

Despite the importance of smoke-free policies in the workplace, most manufacturing facilities surveyed allowed indoor smoking and few helped smokers quit. Companies with unions were more likely to cater to their smoking employees. Manufacturing facilities provide an opportunity to protect large numbers of adult workers from the hazards of secondhand smoke and to provide quit assistance for smokers.

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

1. To categorize workplace interventions for smoking cessation tested in controlled studies and to determine the extent to which they help workers to stop smoking.2. To collect and evaluate data on costs and cost effectiveness associated with workplace interventions.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialized Register (July 2013), MEDLINE (1966 - July 2013), EMBASE (1985 - June 2013), and PsycINFO (to June 2013), amongst others. 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

One author extracted information relating to the characteristics and content of all kinds of interventions, participants, outcomes and methods of the studies, and a second author checked them. For this update we have conducted meta-analyses of the main interventions, using the generic inverse variance method to generate odds ratios and 95% confidence intervals.

MAIN RESULTS

We include 57 studies (61 comparisons) in this updated review. We found 31 studies of workplace interventions aimed at individual workers, covering group therapy, individual counselling, self-help materials, nicotine replacement therapy, and social support, and 30 studies testing interventions applied to the workplace as a whole, i.e. environmental cues, incentives, and comprehensive programmes. The trials were generally of moderate to high quality, with results that were consistent with those found in other settings. Group therapy programmes (odds ratio (OR) for cessation 1.71, 95% confidence interval (CI) 1.05 to 2.80; eight trials, 1309 participants), individual counselling (OR 1.96, 95% CI 1.51 to 2.54; eight trials, 3516 participants), pharmacotherapies (OR 1.98, 95% CI 1.26 to 3.11; five trials, 1092 participants), and multiple intervention programmes aimed mainly or solely at smoking cessation (OR 1.55, 95% CI 1.13 to 2.13; six trials, 5018 participants) all increased cessation rates in comparison to no treatment or minimal intervention controls. Self-help materials were less effective (OR 1.16, 95% CI 0.74 to 1.82; six trials, 1906 participants), and two relapse prevention programmes (484 participants) did not help to sustain long-term abstinence. Incentives did not appear to improve the odds of quitting, apart from one study which found a sustained positive benefit. There was a lack of evidence that comprehensive programmes targeting multiple risk factors reduced the prevalence of smoking.

AUTHORS' CONCLUSIONS

1. We found strong evidence that some interventions directed towards individual smokers increase the likelihood of quitting smoking. These include individual and group counselling, pharmacological treatment to overcome nicotine addiction, and multiple interventions targeting smoking cessation as the primary or only outcome. 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. We failed to detect an effect of comprehensive programmes targeting multiple risk factors in reducing the prevalence of smoking, although this finding was not based on meta-analysed data. 3. There was limited evidence that participation in programmes can be increased by competitions and incentives organized by the employer, although one trial demonstrated a sustained effect of financial rewards for attending a smoking cessation course and for long-term quitting. Further research is needed to establish which components of this trial contributed to the improvement in success rates.4. Further research would be valuable in low-income and developing countries, where high rates of smoking prevail and smoke-free legislation is not widely accepted or enforced.

A qualitative examination of the positive and negative consequences associated with going tobacco-free in substance abuse treatment: the NY State experience

INTRODUCTION

In 2008, the New York State (NYS) Office of Alcoholism and Substance Abuse Services (OASAS) required all state-funded or state-certified addiction treatment programs to be 100% tobacco-free. The regulation prohibits the use or possession of all tobacco products by patients, employees, volunteers, and visitors. This includes exterior grounds and vehicles owned, leased, or operated by the facility. Addiction treatment centers are also required to screen patients for tobacco use and incorporate tobacco cessation into treatment programming. This study examined the perceived effectiveness of this regulation from the perspective of counselors and clinical supervisors.

METHODS

Qualitative data were collected from 261 counselors and 80 clinical supervisors working in 50 free-standing substance abuse treatment programs throughout NYS. Questions asked about the perceived positive and negative consequences of the OASAS regulation approximately 1 year after its implementation.

RESULTS

The findings indicate mixed reactions to the regulation. A wide range of positive and negative consequences were identified, which were generally consistent across counselor and clinical supervisor reports. The most commonly reported positive outcomes were positive behavior change (e.g., less smoking, increased intentions to quit) and increased awareness about smoking (e.g., dangers, available assistance to quit). The most commonly reported negative consequences were reinforcing addict behaviors among patients (e.g., lying, "dealing" cigarettes) and enforcement problems (e.g., difficulty enforcing, policing for compliance).

CONCLUSION

Findings have implications for the implementation of tobacco-free regulations in substance abuse treatment programs.

Going tobacco-free: predictors of clinician reactions and outcomes of the NY State Office of Alcoholism and Substance Abuse Services tobacco-free regulation

In an effort to reduce patient tobacco dependence and create healthier work environments, New York State (NYS) mandated 100% tobacco-free addiction treatment programs for state funded or certified facilities in 2008. We present the results of a longitudinal study examining how local implementation features shape clinician reactions to the regulation and influence post-regulation clinician behavior and strain. A cohort of 147 clinicians associated with 13 treatment organizations throughout NYS completed a survey prior to the passage of the regulation and again approximately 1 year post-regulation. Findings reveal that local implementation features of clinician participation in the planning for change, the provision of change-related information, and perceived organizational support predicted perceptions of change management fairness, which in turn predicted clinical practice behaviors to support smoking cessation, as well as psychological and behavioral strain. In contrast, self-efficacy for change was neither related to local implementation nor clinician outcomes. Practical implications are discussed.

Perceived risk and benefit for self and others as predictors of smokers' attitudes towards smoking restrictions

Studies have investigated perceived own risk as a predictor of behavioural change, but only few have investigated perceived risk to others. However, many risks are distributed, affecting other people as much as the 'agents' of the behaviour in question. Further, research on health perceptions has focussed more on risk than benefit even though people generally choose to engage in behaviours because of benefits not risks. The present study investigated the acceptance of smoking restrictions in Germany, a country that at the time of conducting the research had few restrictions on smoking. Smokers (N = 147) rated the benefits and risks of smoking for themselves and others, and their attitudes towards smoking restrictions. We replicated comparative optimism and reality constraints concerning smoking risks. Additionally, we found that participants overestimated their own benefits compared to other smokers ('comparative utility'). Importantly, own benefits but risks to others best predicted the acceptance of smoking regulations. Moreover, smokers who intended to quit differed from those who did not intend to quit. These findings are potentially important for policy makers aiming to broaden acceptance of regulations for risky behaviours: It may be more effective to remind people they are putting others at risk rather than themselves.

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.

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.

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.

Nicotine self-administration: cigarette versus nicotine gum diurnal topography

The few extant reports examining the relationship between diurnal patterns of pre-cessation smoking and cessation nicotine replacement use suggest that this relationship may be important in preventing smoking relapse. The current study evaluated three interventions to increase nicotine gum use: standard treatment (ST, N = 31), ST plus brief feedback about nicotine attitudes and knowledge (BF, N = 32), or BF plus contingent monetary reinforcement for nicotine gum use (CM, N = 34). Subsets of the 97 randomized subjects were selected based on availability of adequate data for analyses: baseline phase (i.e., 6-7 days of ad libitum smoking, N = 63) or the treatment phase (i.e., 13-15 days of treatment, N = 47). For both cigarettes and nicotine gum, participants showed a characteristic pattern of increasing use during the morning hours, followed by stable use in the afternoon and evening, with a steep decrease prior to sleep onset. Patterns of diurnal gum use did not differ by compliance intervention. Greater morning use of cigarettes or gum was associated with smoking relapse while greater evening and night use of cigarettes or gum was associated with abstinence. Understanding of diurnal patterns of smoking and NRT use may ultimately inform tailored scheduling of NRT.

Impact of home smoking rules on smoking patterns among adolescents and young adults

INTRODUCTION

Smoking restrictions in public places have been shown to reduce cigarette consumption and may reduce smoking prevalence. Evidence is emerging that smoke-free policies in nonpublic places may have a similar effect. The purpose of this study was to determine whether an association exists between household smoking rules and smoking patterns among adolescents (aged 15 to 18 years) and young adults (aged 19 to 24 years) living in parental homes (i.e., the homes of their parents, grandparents, or foster parents).

METHODS

Cross-sectional data from the 1998-1999 Tobacco Use Supplement to the Current Population Survey were analyzed for the association between household smoking rules and smoking behaviors among adolescents and young adults. We used a probability sample of noninstitutionalized adolescents (aged 15 to 18 years) and young adults (aged 19 to 24 years) living in the United States and assessed smoking status, attempts to quit, and smoking intensity.

RESULTS

After controlling for smoking status of others in the household, the odds of ever having smoked, being a current smoker, and smoking more than five cigarettes per day were significantly smaller in households with strict no-smoking policies than in households where smoking was permitted anywhere. These results were relevant for adolescents and young adults.

CONCLUSION

Household smoking rules are a type of antitobacco socialization that help deter adolescents from smoking. The influence of household smoking rules seems to extend beyond adolescence into the young adult years among people who continue to live at home with their parents, grandparents, or foster parents.

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.

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.

A population study of low-rate smokers: quitting history and instability over time

This study used 1 longitudinal and 2 cross-seconal population surveys to compare stability of low-rate daily smokers (less than 5 cigarettes per day) with other daily smokers and occasional smokers. Few low-rate smokers maintained consumption level; 36% retained smoking status after 20 months, compared with 82% and 44% for regular daily and occasional smokers, respectively. In a dynamic process, established smokers quit smoking and/or modified (decreased or increased) consumption. Low-rate and occasional smokers quit at higher rates than regular daily smokers (odds ratios 3:1) but were replenished by new members, many converted from regular daily smoker. The overall trend is an increasing proportion of low-consumption smokers while smoking prevalence declines. The dynamic process has implications for tobacco control efforts and for addiction theory.

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.

[Evaluation of a workplace anti-smoking program at a company with 640 employees]

OBJECTIVES

Awareness of the health risks of passive smoking for non-smokers has led to the development of workplace interventions for smokers, although they are still few in our setting. The objective of this study was to evaluate the efficacy of an anti-smoking program among the workers of a company, in function of changes in the pre- and post-intervention prevalence of smoking in the study population.

METHOD

A pre-intervention questionnaire on smoking (prevalence and attitudes) was administered at a company with 640 employees (92% men, 8% women). An anti-smoking program was carried out inside the company during working hours over the next nine months. The questionnaire was then repeated (post-intervention) in order to evaluate its efficacy based on changes. For employees who answered both questionnaires, paired variables were analyzed.

RESULTS

The pre-intervention questionnaire was answered by 388 employees (60%), 357 men (92%) and 31 women (8%); their mean age was 48.4 years (SD 9.36). The prevalence of smoking was 55%, including daily smokers, sporadic smokers and others. The mean number of cigarettes per day was 17.86 (SD 2.45). The mean level of nicotine dependence measured by the Fagerström test was 3.3 (SD 2.8) out of 10. The post-intervention questionnaire was answered by 206 employees (32%). Among employees who answered both questionnaires (83), analysis of paired data showed a decrease in the prevalence of smoking of 4% and in the number of cigarettes per day from 17.4 (pre-intervention) to 16.4 (post-intervention). The differences were not statistically significant.

CONCLUSIONS

Although the workplace is an appropriate setting for anti-smoking interventions that would contribute to improving the health of smokers, such programs are currently underutilized.

Reviews of evidence regarding interventions to reduce tobacco use and exposure to environmental tobacco smoke

This report presents the results of systematic reviews of effectiveness, applicability, other effects, economic evaluations, and barriers to use of selected population-based interventions intended to reduce tobacco use and exposure to environmental tobacco smoke. The related systematic reviews are linked by a common conceptual approach. These reviews form the basis of recommendations by the Task Force on Community Preventive Services (TFCPS) regarding the use of these selected interventions. The TFCPS recommendations are presented on page 67 of this supplement.

Epidemiologic basis for an occupational and environmental policy on environmental tobacco smoke

ETS contains numerous toxins. Robust epidemiologic evidence implicates ETS as a cause of lung cancer and as a primary cause and source of exacerbation of excess respiratory disease. There is also increasing evidence that ETS may be associated with other outcomes, including heart disease. There is currently little doubt that ETS is an important and avoidable health hazard. Unfortunately, ETS is frequently encountered in the workplace--where it is no safer than in other environments and where it presents hazards to exposed workers and to others. A unique aspect of workplace ETS is that exposure is rarely an outcome of essential manufacturing, extraction, or service delivery processes. Moreover, ETS exposure, with its growing list of known hazards, is preventable by engineering or policy means. Implementation of policies to prevent workplace ETS can be highly effective while entailing low costs and yielding primary and secondary benefits to employers and employees. ACOEM strongly supports an increase in the scope and effectiveness of policies and efforts that protect against exposure to ETS in the workplace and elsewhere. To that end, ACOEM supports voluntary, regulatory, and legislative initiatives to eliminate ETS from the workplace, including public spaces such as bars, casinos, restaurants, schools, day-care centers, and public transportation. ACOEM also encourages employers to provide employee training concerning the health hazards of ETS and voluntary personal smoking-cessation programs.

The relationship between organizational characteristics and the adoption of workplace smoking policies

Organizational-level variables that are hypothesized to influence the level of smoking policy restrictions and the prevalence of smoking control activities were tested in a sample of 1 14 worksites that participated in the Working Well Trial, a national trial of worksite health promotion. Predictors related to more restrictive policies included smaller size, larger percentage of white-collar workers, larger number of complaints about environmental tobacco smoke, less complexity, more formalization, and having a CEO who valued health and employees' well-being. The number of smoking control activities offered in a worksite was predicted by having a larger blue-collar workforce, a higher percentage of female employees, higher levels of workforce stability, and a CEO who valued health and employees' well-being. Efforts to identify predictors of companies' adoption and implementation of workplace-based policies and interventions are an important part of tobacco control efforts and will enhance future intervention and research efforts.

Effect of workplace smoking policies on smoking cessation: results of a longitudinal study

Studies of worksite smoking bans often find that they fail to increase the rate of smoking cessation. To see whether duration of exposure to restrictive policies was an important element, we surveyed workers by phone to examine the effect of being continuously employed at a smokefree worksite for 3 years. Results showed that worksite policy was unrelated to smoking cessation. However, 12% of respondents at smokefree worksites reported that smoking had taken place in their work area, and over 20% reported at least 2 hours of worksite environmental tobacco smoke (ETS) exposure during the prior week. When minimal ETS exposure is used as an indicator of an effectively enforced smoking ban, logistic regression demonstrates that continuous employment at such a worksite strongly predicts smoking cessation. Failure to demonstrate a significant impact of worksite smoking bans on cessation in this and other studies may be due to poor enforcement of smoking policies.

Medium-sized business employees speak out about smoking

A health promotion study, funded by a state health department to meet objectives 3.4 and 3.11 of Healthy People 2000, was designed to: (1) identify tobacco use; (2) assess employees' beliefs on one's health and family member's health; and (3) assess the type of smoking policies favored. Using the Health Belief Model, it was hypothesized that there were differences in the health beliefs of tobacco users, former users, and never users. A 34-item questionnaire was administered to 1090 employees with a return rate of 603 (55%).

RESULTS

tobacco users perceived weight control and reduction of tension as benefits; they accepted warning label as hazardous but reported smokeless not as harmful; they perceived heart disease and cancer as related to tobacco use; and 62% had tried to quit smoking. Former and never users wanted "total ban policies" while, tobacco users wanted "designated areas" for smoking. All perceived their smoking and environmental tobacco smoke hazardous to their health and the health of family.

The effects of household and workplace smoking restrictions on quitting behaviours

OBJECTIVE

To assess the association of household and workplace smoking restrictions with quit attempts, six month cessation, and light smoking.

DESIGN

Logistic regressions identified the association of household and workplace smoking restrictions with attempts to quit, six month cessation, and light smoking.

SETTING

Large population surveys, United States.

SUBJECTS

Respondents (n = 48,584) smoked during the year before interview in 1992-1993, lived with at least one other person, and were either current daily smokers or were former smokers when interviewed.

MAIN OUTCOME MEASURES

The outcome measures were an attempt to quit during the last 12 months, cessation for at least six months among those who made an attempt to quit, and light smoking (< 15 cigarettes a day).

RESULTS

Smokers who lived (odds ratio (OR) = 3.86; 95% confidence interval (CI) = 3.57 to 4.18) or worked (OR = 1.14; 95% CI = 1.05 to 1.24) under a total smoking ban were more likely to report a quit attempt in the previous year. Among those who made an attempt, those who lived (OR = 1.65, 95% CI = 1.43 to 1.91) or worked (OR = 1.21, 95% CI = 1.003 to 1.45) under a total smoking ban were more likely to be in cessation for at least six months. Current daily smokers who lived (OR = 2.73, 95% CI = 2.46 to 3.04) or worked (OR = 1.53, 95% CI = 1.38 to 1.70) under a total smoking ban were more likely to be light smokers.

CONCLUSIONS

Both workplace and household smoking restrictions were associated with higher rates of cessation attempts, lower rates of relapse in smokers who attempt to quit, and higher rates of light smoking among current daily smokers.

Impact of the Working Well Trial on the worksite smoking and nutrition environment

This article reports the effect of a worksite cancer control intervention on aspects of the physical and social environment related to dietary and smoking behaviors of employees. Data are from 111 intervention and control worksites that participated in the Working Well Trial. Employee surveys and interviews with key organizational informants assessed environmental and normative changes relevant to nutrition and tobacco use. Results indicated significant effects of the intervention on all nutrition outcomes: access to healthy food, nutritional information at work, and social norms regarding dietary choice. Significant benefits were not found for smoking norms or smoking policies. However, changes occurred in both the control and intervention sites on these variables. This first large analysis of environmental and normative effects of a worksite intervention is consistent with the employee behavior change findings for the trial and serves as a model for future analyses of multilevel worksite health promotion programs.

The impact of smoke-free workplaces on declining cigarette consumption in Australia and the United States

OBJECTIVES

This study estimates the contribution of smoke-free workplaces to the recent national declines in cigarette consumption in Australia and the United States.

METHODS

Nineteen studies of the impact of smoke-free workplaces on workday cigarette consumption were reviewed. The number and cost of cigarettes forgone were calculated and extrapolated to a scenario in which all indoor work areas were smoke-free.

RESULTS

Of the 19 studies, 18 reported declines in daily smoking rates, and 17 reported declines in smoking prevalence. Smoke-free workplaces are currently responsible for an annual reduction of some 602 million cigarettes, or 1.8% of all cigarettes that might otherwise be consumed, in Australia, and an annual reduction of 9.7 billion cigarettes (2%) in the United States. Approximately 22.3% of the 2.7 billion decrease in cigarette consumption in Australia between 1988 and 1995 can be attributed to smoke-free workplaces, as can 12.7% of the 76.5 billion decrease in the United States between 1988 and 1994.

CONCLUSIONS

If workplaces were universally smoke-free, the number of cigarettes forgone annually would increase to 1.14 billion (3.4%) in Australia and 20.9 billion (4.1%) in the United States.

[Cigarette smoking among bank employees]

OBJECTIVE

To describe the prevalence of cigarette smoking and its association with other risk factors for chronic diseases among active workers of communication and data processing centers of a Bank.

METHODS

Cross-sectional study in a simple random sample of 647 active workers of the bank. The data were collected in the work environment, through self-administered questionnaires.

RESULTS

The prevalence of cigarette smoking was 29.5% (95% Confidence Interval (CI): 27.5%-31.5%), 31.1% (95% CI: 26.2%-35.8%) among men and 27.8% (95% CI: 22.6%-32.9%) among women. On average, males started smoking at the age of 17.6 years and women at the age of 19.4. High prevalence of heavy smokers was observed among men and women (53% and 42%, respectively, smoked more than 20 cigarettes per day). Smokers were older, more likely to be divorced, separated and widowed, to have high blood pressure, to drink alcoholic beverages more often, and to exercise less often than to non-smokers. Those who gave up smoking were older, drank more alcoholic beverages, and were more often overweight.

CONCLUSION

The considerable frequency of smoking and other risk factors for chronic diseases among those workers may be an indication of the need for new strategies for health interventions. Opportunities for preventive actions, which are more effective and less costly, may have been lost.

A review of the health impact of smoking control at the workplace

PURPOSE

To summarize and provide a critical review of worksite health promotion program evaluations published between 1968 and 1994 that addressed the health impact of worksite smoking cessation programs and smoking policies.

METHODS

A comprehensive literature search conducted under the auspices of the Centers for Disease Control and Prevention identified 53 smoking cessation program evaluation reports, of which 41 covered worksite single-topic cessation programs. Nine additional reports were located through manual search of citations from published reports and reviews. These 50 reports covered 52 original data-based studies of cessation programs. The search produced 19 reports for tobacco policy evaluations, of which 12 addressed health impact. An additional 17 reports were located by the authors. These 29 reports covered 29 studies of policy impact.

SUMMARY OF IMPORTANT FINDINGS

Smoking cessation group programs were found to be more effective than minimal treatment programs, although less intensive treatment, when combined with high participation rates, can influence the total population. Tobacco policies were found to reduce cigarette consumption at work and worksite environmental tobacco smoke (ETS) exposure.

CONCLUSIONS

The literature is rated suggestive for group and incentive interventions; indicative for minimal interventions, competitions, and medical interventions; and acceptable for the testing of incremental effects. Because of the lack of experimental control, the smoking policy literature is rated as weak, although there is strong consistency in results for reduced cigarette consumption and decreased exposure to ETS at work.

The Ontario ban on smoking on school property: perceived impact on smoking

We evaluated the impact of the November 1994 ban on smoking on school property in Ontario. Telephone interviews were conducted at the end of the 1995-96 school year with 213 high school administrators. Almost all high schools (96%) prohibit smoking on school property. Although some smoking still occurs on school property, the location of smoking by students has changed, giving rise to perceptions of both benefits and risks, as well as varying complaints from parents, students, neighbours, and nearby businesses. Most of the problems arising from the ban are viewed as minor. Local conditions, particularly the geographic environment of the school, appear to be important determinants of complaints and problems. While sizeable minorities of school administrators felt the ban had favourable effects, the majority perceived little effect on either smoking behaviour or attitudes towards smoking.

Association of the health-promoting workplace with trade unionism and other industrial factors

PURPOSE

The study examines associations of five healthy workplace attributes with trade unionism and nine other industrial and sociodemographic factors. The aims were to illustrate the measurement of workplace health promotion indicators in Western Australia and to identify associations leading to a better understanding of determinants of the healthy workplace.

DESIGN

Personal and telephone cross-sectional surveys were performed using population-based sampling frames. The overall response rate was 72%.

SETTING

Workplaces in Western Australia.

SUBJECTS

Random samples of household respondents aged 16 to 69 years in 1992 (n = 1310) and 1994 (n = 1113).

MEASURES

Measures of association between healthy workplace attributes and trade unionism were adjusted for workplace location, size, sector, and industrial classification.

RESULTS

Trade unionism was strongly associated with healthy catering practices (adjusted OR 2.05; 95% CI 1.30 to 3.23), sun protection practices (2.66; 1.69 to 4.17), disability access (1.47; 1.10 to 1.95), and worksite health promotion programs (2.56; 2.07 to 3.17). A weak and nonsignificant association was observed with restrictive smoking policies (1.21; .95 to 1.55). Generally, healthy workplace attributes were reported less often by respondents working in rural locations, in the private sector, and at small worksites. There was no consistent relationship with sociodemographic factors, including an index of social disadvantage, but members of blue-collar occupations experienced a low prevalence of restrictive smoking policies.

CONCLUSIONS

The study raises the hypothesis, but cannot confirm, that trade unions could provide a means for employees to pursue the creation of a health-promoting workplace. Small business represents an excellent target for health promotion activities.

The financial impact of changes in personal health practices

The impact of changes in health practices on medical claims costs between 1985-1987 and 1988-1990 was examined among 796 employees. Employees completed a health risk appraisal in 1985 and 1988 and were categorized into health risk levels. High-cost status and high-risk status were significantly associated at both times. The percentage of employees with high-risk status decreased from 31.8% to 25.3% between 1985 and 1988 (P < 0.01). Changes in average costs and the percentage with high-cost status followed the risk change. The largest increase in average costs occurred in employees who moved from low-risk to high-risk status. The greatest reduction in average costs occurred in employees who moved from high-risk to low-risk status. Median costs were not as sensitive to risk change. The findings provide strong evidence that improving individual health status is associated with financial benefits.

Tobacco control: a brief review of its history and prospects for the future

Smoking prevalence among American adults is at its lowest point in the last 30 years, and there is unprecedented popular support for tobacco control measures. The financial resources to carry on the battle for tobacco control are still heavily stacked in favor of the industry, which by current estimates is worth $45 billion, including $6 billion spent each year on advertising and promotion alone. Nonetheless, industry executives must realize that, even if they can win individual battles, they are losing the war. This article has discussed key events in the history of tobacco control, as well as some of the most innovative strategies currently being used for tobacco control. Although it is important that tobacco control efforts be disseminated widely and through novel channels, the challenge facing public health advocates in the next several decades will be to anticipate the industry's response to key initiatives, as well as to launch organized and strategic counterattacks against efforts to dissuade acceptance of such initiatives. The history of tobacco control demonstrates that public health advocacy resources should be strategically focused in precisely the areas in which the industry feels most vulnerable (e.g., nicotine addiction, regulation of nicotine, environmental tobacco smoke), rather than in areas in which the industry maintains a vocal presence for the purposes of public relations (e.g., youth access). Through its lobbying efforts and financial clout, the tobacco industry has played a key role in the development of public health policy. Although it is no secret that the tobacco industry regularly makes campaign contributions to both Republicans and Democrats, the impact of these donations on public policy making have only recently begun to be quantified and documented. Moore et al found that the more tobacco money a politician received, the less likely he or she was to support tobacco control legislation. Similar distortional effects of tobacco money have been demonstrated at the state level. The political expenditure of 12 tobacco firms increased 10-fold in California after the implementation of Proposition 99 in California--from $790,050 in the 1985-1986 election, to $7,615,091 in the 1991-1992 election. In an analysis of the behavior of the California legislature between 1991 and 1992, a statistically significant relationship was found between members' receipt of tobacco money and their likelihood of opposing tobacco control measures. Tobacco control advocates as well as health professionals in general have an important role to play in holding their legislators accountable for developing public health policy that reflects the concerns of their constituencies, not of the tobacco lobby. Public health advocates should pay particular attention to the recent regulations placed on cigarettes as a key tobacco control strategy for the next several decades. For the first time in the history of the United States, a President has introduced legislation that will allow a governmental agency to regulate tobacco. The FDA has faced relentless attacks by the tobacco industry, and it will continue to be a target. Public health advocates and health care providers have a critical role to play in the FDA's efforts to bring this issue to fruition. If the public health community fails to support this initiative and create an active and forceful opposition to the industry's efforts to derail it, it is likely that the impact on tobacco control efforts will be resounding and far-reaching.

Smoking behavior and attitude toward smoking regulations and passive smoking in the workplace. A study among 974 employees in the German metal industry

BACKGROUND

Smoking regulations at the workplace have been found to be acceptable and effective in many studies conducted in the United States. There is limited knowledge, however, on acceptance and effects of smoking regulations in European countries, particularly among blue collar employees.

METHODS

We conducted a survey on smoking behaviour and attitude toward smoking regulations and passive smoking in a South German metal company. A self-administered questionnaire was mailed to 1,500 predominantly blue collar employees of whom 974 participated in the study (response rate 64.9%).

RESULTS

About 30% of the employees were not allowed to smoke at their immediate work area. Among them, about 95% of both smokers and nonsmokers agreed with this smoking policy. More than 60% of nonsmoking blue collar workers were bothered by passive smoking at work whether or not smoking was allowed at their immediate work area. In contrast, the proportion of nonsmoking white collar employees who were bothered by passive smoking varied from 52% if smoking was allowed at their immediate work area to 18% if smoking was not allowed. Prevalence of active smoking and average amount of smoking among active smokers were considerably lower among employees who were not allowed to smoke at work than among other employees. These differences were partly due to confounding by occupation, however, which was strongly related to both smoking habits and smoking policy.

CONCLUSIONS

Our results, which confirm and extend previous findings, give further support to the acceptability and potential effectiveness of smoking regulations at the workplace. Particular efforts should be devoted to limit both active and passive smoking among blue collar employees.

The organizational implications of smokeless tobacco use in the lumber mill industry

Although much is known about the characteristics of employees who smoke cigarettes, very little is known about workers who use smokeless tobacco. The current study was designed to understand the characteristics of smokeless tobacco users in relation to their performance at work and compare them with smokers and former tobacco users. Data were collected via interviews and questionnaires from a random sample of employees working at Pacific Lumber Company (N = 146), the largest single-site lumber mill in California. A total of 63 smokeless tobacco users (21 of whom also smoked cigarettes), 43 cigarette smokers, and 40 employees who had successfully quit using tobacco (34 of whom previously used cigarettes only) provided information about their health behavior, quality of work life, and performance at work. Analyses revealed that smokeless tobacco users reported less healthful sleep patterns, drank alcohol more often, were intoxicated more often, reported less job satisfaction and organizational commitment, and reported that both chewers and smokers do not work as hard and take more breaks than do tobacco-free employees (quitters). Specific differences among chewers-only, smokers-only, smokers-and-chewers, and quitters are presented. Results suggest the organizational value of developing worksite cessation programs for smokeless tobacco users.

Response to smoking as a function of prior smoking amounts

Smoking patterns are changing to accommodate new environmental smoking restrictions. The current study explored the effects of prior smoking amounts on the behavioral, physiological, and subjective effects of smoking a single cigarette. Ten smokers (six females, four males) each participated in four laboratory sessions of 6 h duration. During each session, they smoked 0, 2, 5, or 11 cigarettes which were evenly spaced throughout the 6-h period at intervals ranging from 30 min (11 cigarettes) to 120 min (2 cigarettes), with condition order determined by a Latin square. At the end of each session, all smoked a final cigarette. Response to the last cigarette of the 6-h session was influenced by pretreatment smoking amounts. Number of puffs drawn from the cigarette (15.0, 14.1, 13.3, and 10.1) was inversely related to prior smoking density, as was heart rate increase (5.8, 4.0, 2.4, and 1.3 bpm). Three physical symptoms of smoking, dizzy, lightheaded and tingling, were significantly greater when preceded by 6 h of no smoking than when preceded by smoking at 30-min intervals. However, these symptoms were rated as mild (19-27 on a 100-point scale) even when no cigarettes had been smoked. These results suggest some dissipation of acute tolerance after 6 h of smoking abstinence. Liking and satisfaction ratings were inversely related to the pretreatment density of smoking. Liking scores for the last cigarette were 85, 71, 68 and 48 (on a 100-point analog scale) when 0, 2, 5 and 11 cigarettes had been smoked. Overall, the study showed that physiological and subjective effects of smoking are modulated by recent histories of smoking.(ABSTRACT TRUNCATED AT 250 WORDS)
