Short-term impact of a university based smoke free campaign

Development and evaluation of smoke-free or tobacco-free policies in university settings: a systematic scoping review

We conducted a systematic scoping review to map the available evidence on smoke-free or tobacco-free (SF/TF) university policies globally. We specifically looked at (i) how policies were developed and communicated and (ii) what indicators were used to evaluate their impact. We searched for peer-reviewed literature, published up to January 2020, across 10 multi-disciplinary databases. We followed a duplicate, independent data selection, and charting process. We inductively categorized the studies according to the research design and objective of 'process' and 'impact evaluation'. We identified 75 unique studies across 23 countries conducted between 1993 and 2019. Most studies were conducted in the United States (46/75, 61.3%), were based on quantitative research design and focused on impact evaluations; a third (n = 28) reported both process and impact evaluations (37.3%). Community engagement and multi-channel communication strategies were mostly used to disseminate SF/TF policies. The impact was determined by a wide range of indicators for knowledge, attitudes and behaviors related to policies. There is a mature, relevant body of literature describing the development and evaluation of SF/TF policies in universities. Future reviews could quantify the impact of the bans and may consider process indicators as moderating factors to explain the potential heterogeneity of results.

Smoke-Free Universities Help Students Avoid Establishing Smoking by Means of Facilitating Quitting

BACKGROUND

This study aimed to clarify whether smoke-free policies affect the initiation or the quitting of smoking among young adults.

METHODS

In this natural quasi-experiment study, three universities with different enforcement of smoke-free policies were considered in Kazan City, Russian Federation. Exposure data were collected in 2008-2009 through measurement of particulate matter concentrations in typical sets of premises in each university to distinguish smoke-free universities (SFU) and those not smoke-free (NSFU). All present third year students were surveyed in class in April-June 2011. Number of valid questionnaires equaled 635. The questionnaire was adapted from the Health Professions Students Survey and contained questions on smoking initiation, current tobacco use, willingness to quit, quit attempts, percep-tion of smoke-free policies enforcement, and the demographic data.

RESULTS

Among students of SFU, the percentage of current smokers was smaller than in NSFU: 42% vs. 64% in men and 32% vs. 43% in women. Prevalence of daily smoking was 11-12% in SFU, 26% in NSFU overall and 42% among male students. No advantage of SFU in limiting smoking initiation was found. Percentage of former smokers in SFU was 33% vs. 10% in NSFU. Among current smokers, 57% expressed willingness to quit in SFU and only 28% in NSFU. About 60% of current smokers in SFU attempted to quit within a year and only 36% did so in NSFU with 23% vs. 3% having done three or more attempts.

CONCLUSION

Smoke-free universities help young adults to avoid establishing regular smoking by means of facilitating quitting smoking.

Clearing the air: improving smoke-free policy compliance at the national oncology hospital in Armenia

Background

Smoke-free policies shown to reduce population exposure to secondhand smoke (SHS) are the norm in hospitals in many countries around the world. Armenia, a transition economy in the South Caucasus, has one of the highest male smoking rates in the European region. Although smoking in healthcare facilities has been banned since 2005, compliance with this ban has been poor due to lack of implementation and enforcement mechanisms and social acceptability of smoking. The study aimed to develop and test a model intervention to address the lack of compliance with the de jure smoking ban. The national oncology hospital was chosen as the intervention site.

Methods

This study used employee surveys and objective measurements of respirable particles (PM_2.5) and air nicotine as markers of indoor air pollution before and after the intervention. The intervention developed in partnership with the hospital staff included an awareness campaign on SHS hazards, creation of no-smoking environment and building institutional capacity through training of nursing personnel on basics of tobacco control. The survey analysis included paired t-test and McNemar’s test. The log-transformed air nicotine and PM_2.5 data were analyzed using paired t-test.

Results

The survey showed significant improvement in the perceived quality of indoor air, reduced worksite exposure to SHS and increased employees’ awareness of the smoke-free policy. The number of employees reporting compliance with the hospital smoke-free policy increased from 36.0% to 71.9% (p < 0.001). The overall indoor PM_2.5 concentration decreased from 222 μg/m³ GM (95% CI = 216-229) to 112 μg/m³ GM (95% CI = 99-127). The overall air nicotine level reduced from 0.59 μg/ m³ GM (95% CI = 0.38-0.91) to 0.48 μg/ m³ GM (95% CI = 0.25-0.93).

Conclusions

The three-faceted intervention developed and implemented in partnership with the hospital administration and staff was effective in reducing worksite SHS exposure in the hospital. This model can facilitate a tangible improvement in compliance with smoke-free policies as the first step toward a smoke-free hospital and serve as a model for similar settings in transition countries such Armenia that have failed to implement the adopted smoke-free policies.

Comparing Two Observational Measures to Evaluate Compliance With Tobacco-Free Campus Policy

Despite potential benefits of tobacco-free campus policies, compliance remains a challenge. Observational measures hold the most promise in determining compliance with these policies. There is need for further study to determine validity of observational measures of compliance with tobacco-free campus policies. The purpose of this study was to determine the validity of two observational measures of compliance with a tobacco-free campus policy: direct observation of violators and cigarette butts. Data collection took place over a 1-year time period. Direct observation was operationally defined as the number of observed violators in hot spots. A cigarette butt protocol previously found to be reliable was used to count the number of butts in campus hot spots. Results indicated a positive relationship between number of violators observed per visit and number of cigarette butts collected. Although most of the hot spots exhibited two or fewer violators per visit and 100 butts or fewer per collection, the data points outside this range supported a positive association between observed violators per visit and cigarette butts. The findings support that direct observation of violators is a valid measure of compliance compared to cigarette butts. Given available resources, using one or the other as evaluation measures is warranted.

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.

Population approaches to improve diet, physical activity, and smoking habits: a scientific statement from the American Heart Association

BACKGROUND

Poor lifestyle behaviors, including suboptimal diet, physical inactivity, and tobacco use, are leading causes of preventable diseases globally. Although even modest population shifts in risk substantially alter health outcomes, the optimal population-level approaches to improve lifestyle are not well established.

METHODS AND RESULTS

For this American Heart Association scientific statement, the writing group systematically reviewed and graded the current scientific evidence for effective population approaches to improve dietary habits, increase physical activity, and reduce tobacco use. Strategies were considered in 6 broad domains: (1) Media and educational campaigns; (2) labeling and consumer information; (3) taxation, subsidies, and other economic incentives; (4) school and workplace approaches; (5) local environmental changes; and (6) direct restrictions and mandates. The writing group also reviewed the potential contributions of healthcare systems and surveillance systems to behavior change efforts. Several specific population interventions that achieved a Class I or IIa recommendation with grade A or B evidence were identified, providing a set of specific evidence-based strategies that deserve close attention and prioritization for wider implementation. Effective interventions included specific approaches in all 6 domains evaluated for improving diet, increasing activity, and reducing tobacco use. The writing group also identified several specific interventions in each of these domains for which current evidence was less robust, as well as other inconsistencies and evidence gaps, informing the need for further rigorous and interdisciplinary approaches to evaluate population programs and policies.

CONCLUSIONS

This systematic review identified and graded the evidence for a range of population-based strategies to promote lifestyle change. The findings provide a framework for policy makers, advocacy groups, researchers, clinicians, communities, and other stakeholders to understand and implement the most effective approaches. New strategic initiatives and partnerships are needed to translate this evidence into action.

Changes in smoking prevalence, attitudes, and beliefs over 4 years following a campus-wide anti-tobacco intervention

OBJECTIVE

The current study examined the effectiveness of an institutional intervention aimed at decreasing prevalence of tobacco use and exposure to smoke on campus over a 4-year period.

PARTICIPANTS

Participants were undergraduate students (N = 4,947) enrolled at a large Midwestern university between 2007 and 2010.

METHODS

In 2008, tobacco use was banned on campus. Additionally, campus-wide tobacco cessation services and information were provided to all students. A self-report measure assessing demographics, smoking prevalence, attitudes, and smoke exposure was administered at baseline and at 3 time points over the following 3 years.

RESULTS

The percentage of more frequent smokers and less frequent smokers decreased across assessment points. The program appeared to be less effective for female smokers than male smokers. Further, a significant change in attitudes and secondhand smoke exposure was observed.

CONCLUSIONS

It appears that a campus-wide tobacco ban is a well-accepted and effective prevention method for smoking. This study lends considerable support for efforts towards smoke-free campuses.

Threatening Intergroup Relationships

Five experiments investigated among nonsmokers with initial antismoking attitudes conformity to a norm of intergroup tolerance and nondiscrimination (i.e., a counterattitudinal norm) as a function of the personal versus categorical referent used in intergroup comparisons (self-categorization level), the motivation to respond without prejudice, and the perceived ingroup threat. Results showed that conformity (i.e., a reduction of support for antismoking actions) was moderated by the ingroup threat in the category-referent condition (i.e., conformity was observed only when the perceived threat was low), but by the internal motivation to respond without prejudice in the personal-referent condition. These findings suggest the existence of different moderators of conformity as a function of the self-categorization level.

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.

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.

WITHDRAWN: Interventions for preventing tobacco smoking in public places

BACKGROUND

Environmental tobacco smoke is a health hazard. Reducing exposure to tobacco smoke in public places is a widespread public health goal. There is, however, considerable variation in the extent to which this goal has been achieved in different settings and societies. There is therefore a need to identify effective strategies for reducing tobacco consumption in public places.

OBJECTIVES

To evaluate the effectiveness of interventions to reduce tobacco consumption in public places.

SEARCH STRATEGY

We searched the Tobacco Addiction Review Group trials register, MEDLINE and EMBASE in March 2006. We handsearched a key journal and abstracts from international conferences on tobacco. We checked the bibliographies of identified studies and reviews for additional references.

SELECTION CRITERIA

We considered randomized and controlled trials, controlled and uncontrolled before-and-after studies and interrupted time series. The main outcome of interest was levels and measures of compliance with bans and restrictions. We considered strategies aimed at populations, including education campaigns, written material, non-smoking and warning signs, and comprehensive strategies. We also considered strategies aimed at individual smokers.

DATA COLLECTION AND ANALYSIS

Information relating to the characteristics and content of all kinds of interventions, participants, outcomes and methods of each study was abstracted by one reviewer and checked by two others. Studies were combined using qualitative narrative synthesis.

MAIN RESULTS

Twenty of 25 studies reporting information about interventions to reduce smoking in public places met all the inclusion criteria. Three were controlled before-and-after studies and 17 were uncontrolled before-and-after studies. The most effective strategies used comprehensive, multi-component approaches to implement policies banning smoking within institutions. Less comprehensive strategies, such as posted warnings and educational material, had a moderate effect. Five studies showed that prompting individual smokers had an immediate effect, but such strategies are unlikely to be acceptable as a public health intervention.

AUTHORS' CONCLUSIONS

Carefully planned and resourced, multi-component strategies effectively reduced smoking within public places. Less comprehensive strategies were less effective. Most studies were done in the USA and, despite increasing evidence from Europe, there is a need to identify ways in which these strategies can be adopted and used in countries with different attitudes to tobacco use. Future studies should also consider the use of more rigorous experimental designs.

An intensive group therapy programme for smoking cessation using nicotine patch and internet mailing supports in a university setting

AIMS

Despite the growing literature on workplace tobacco control policies, very few studies have evaluated the role of smoking cessation programme as one of these policies in a university setting. We aimed to investigate the efficacy of intensive cessation programme delivered in a group format using nicotine patch therapy and internet mailing supports for our university employees.

METHODS

From January 2003, we conducted the group therapy programme for smoking cession seven times in Okayama University, Japan. This programme consisted of nicotine patch therapy and on-line supporting system. Smoking status was regularly assessed by direct interviews.

RESULTS

A total of 102 employees were enrolled in this programme, of whom 101 initiated their smoking cessation. One hundred participants (99%) received nicotine patch therapy, and its toxicities were generally mild. Of the 94 employees who could be follow-up for a year after the cessation, 50 (53%) sustained abstinence for a year. Multivariate analysis revealed that writing and sending e-mail messages within the first 1 week were significant factors affecting long-term cessation. The type of position also affected the cessation rate.

CONCLUSION

This study suggests that our programme in a university setting seems to be effective mainly because of peer-supports among the participants through regular face-to-face meetings and their own mailing supports.

Preferred smoking policies at 30 Pacific Northwest colleges

OBJECTIVE

Research shows that restrictive smoking policies on college campuses could discourage smoking onset or help facilitate cessation efforts among students. However, many colleges and universities are reluctant to establish restrictive smoking policies for fear of student objections. Our study examined preferred smoking policies among college students in the Pacific Northwest.

METHODS

We conducted a baseline cross-sectional descriptive study of a grouped randomized controlled trial at 30 four-year colleges and universities in Idaho, Oregon, and Washington.

RESULTS

Of the 14,237 students who responded to the survey, 17.3% were smokers. All respondents were knowledgeable about indoor smoking policies; however, there was incongruence regarding outside policies. Some 88% of never smokers wanted a completely smoke-free indoor policy, while a substantial percentage (58%) of smokers concurred (odds ratio [OR]=0.19, p<0.001). Fewer respondents were supportive of outdoor policies (43.3% for never smokers and 6.9% for smokers). Respondents agreed that the desire to breathe clean air should have priority over the desire to smoke; however, smokers agreed to a lesser extent (97.5% for never smokers and 81.5% for smokers [OR=0.012, p<0.001]).

CONCLUSION

Both non-smokers and smokers have high approval rates for restrictive smoking policies on campus. Administrators can use this information to help enact restrictive campus smoking policies.

Employee's perceived exposure to environmental tobacco smoke, passive smoking risk beliefs and attitudes towards smoking: a case study in a university setting

Despite the growing literature on workplace smoking policies, few studies have focused on the implementation of such policies in university settings. Smoking in the workplace is still very common in many countries, including Spain. While the law is about to change and more non-smoking policies are to be implemented, it is not clear what kind of restrictions Spanish workers would find acceptable. This study investigated perceived exposure to environmental tobacco smoke (ETS), passive smoking risks beliefs and attitudes towards smoking at the University of Navarra (Spain). A questionnaire was sent by E-mail to 641 randomly selected employees and a response rate of 70.4% was obtained. The survey results suggest that 27.3% of the university employees were smokers and 26.6% were exposed to ETS on a daily basis. The majority of respondents (81.7%) supported a restrictive non-smoking policy. Acceptance among active smokers was significantly lower (59.2 versus 89.3%). Smoking prohibition with the provision of smoking areas was the most favored option (46.9%). Results suggest that employees are ready to restrict smoking in the university, but there was not enough support for a total ban. Employers considering adopting a ban on smoking should be encouraged to conduct a similar survey to identify potential barriers to policy implementation.

Secondhand smoke exposure in the workplace

BACKGROUND

Currently, there is little understanding of the relationship between the strength of workplace smoking policies and the likelihood and duration, not just the likelihood, of exposure to secondhand smoke at work.

METHODS

This study assessed self-reported exposure to secondhand smoke at work in hours per week among a cross-sectional sample of 3650 Massachusetts adults who were employed primarily at a single worksite outside the home that was not mainly outdoors. The sample data were from a larger longitudinal study designed to examine the effect of community-based tobacco control interventions on adult and youth smoking behavior. Participants were identified through a random-digit-dialing telephone survey. Multiple logistic regression and zero-inflated negative binomial regression models were used to estimate the independent effect of workplace smoking policies on the likelihood and duration of exposure to secondhand smoke.

RESULTS

Compared to employees whose workplace banned smoking completely, those whose workplace provided designated smoking areas had 2.9 times the odds of being exposed to secondhand smoke and 1.74 times the duration of exposure, while those with no restrictions had 10.27 times the odds of being exposed and 6.34 times the duration of exposure.

CONCLUSIONS

Workplace smoking policies substantially reduce the likelihood of self-reported secondhand smoke exposure among employees in the workplace and also greatly affect the duration of exposure.

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.

A review of interventions to reduce tobacco use in colleges and universities

BACKGROUND

Interventions have been designed to reduce the prevalence of smoking in college/university students. This review presents a summary and synthesis of the interventions published in English from 1980 to the present.

METHODS

Seven databases were searched for relevant published articles, and reference lists were examined for additional published studies. The studies were categorized as (1) individual approaches, such as on-campus cessation programs, and (2) institutional approaches, such as smoke-free policies. The studies were categorized by type of institution and geographic location, study design, sample demographics, and outcomes.

RESULTS

Fourteen studies were identified; only five received a "satisfactory" rating based on evaluation criteria. Most studies were based on convenience samples, and were conducted in 4-year institutions. Seven studies used comparison groups, and three were multi-institutional. Individual approaches included educational group sessions and/or individual counseling that were conducted on campus mostly by healthcare personnel. None used nicotine replacement or other medications for cessation. The quit rates for both smokeless tobacco and cigarette users varied, depending on definitions and duration of follow-up contact. Institutional interventions focused mainly on campus smoking restrictions, smoke-free policies, antitobacco messages, and cigarette pricing. Results indicated that interventions can have a positive influence on student behavior, specifically by reducing tobacco use (i.e., prevalence of cigarette smoking and use of smokeless products, amount smoked) among college students, and increasing acceptability of smoking policies and campus restrictions among both tobacco users and nonusers.

CONCLUSIONS

While some promising results have been noted, rigorous evaluations of a wider range of programs are needed, along with studies that address cultural and ethnic diversity on campuses.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

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

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

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.

Effects of sixty six adolescent tobacco use cessation trials and seventeen prospective studies of self-initiated quitting

This paper provides a review of the last two and a half decades of research in adolescent and young-adult tobacco use cessation. A total of 66 tobacco cessation intervention studies – targeted or population – are reviewed. In addition, an exhaustive review is completed of adolescent self-initiated tobacco use cessation, involving 17 prospective survey studies.

Average reach and retention across the intervention studies was 61% and 78%, respectively, and was higher when whole natural units were treated (e.g., classrooms), than when units created specifically for the program were treated (e.g., school-based clinics). The mean quit-rate at a three to 12-month average follow-up among the program conditions was 12%, compared to approximately 7% across control groups. A comparison of intervention theories revealed that motivation enhancement (19%) and contingency-based reinforcement (16%) programs showed higher quit-rates than the overall intervention cessation mean. Regarding modalities (channels) of change, classroom-based programs showed the highest quit rates (17%). Computer-based (expert system) programs also showed promise (13% quit-rate), as did school-based clinics (12%).

There was a fair amount of missing data and wide variation on how data points were measured in the programs' evaluations. Also, there were relatively few direct comparisons of program and control groups. Thus, it would be difficult to conduct a formal meta-analysis on the cessation programs. Still, these data suggest that use of adolescent tobacco use cessation interventions double quit rates on the average.

In the 17 self-initiated quitting survey studies, key predictors of quitting were living in a social milieu that is composed of fewer smokers, less pharmacological or psychological dependence on smoking, anti-tobacco beliefs (e.g., that society should step in to place controls on smoking) and feeling relatively hopeful about life. Key variables relevant to the quitting process may include structuring the context of programming for youth, motivating quit attempts and reducing ambivalence about quitting, and making programming enjoyable as possible. There also is a need to help youth to sustain a quit-attempt. In this regard, one could provide ongoing support during the acute withdrawal period and teach youth social/life skills. Since there is little information currently available on use of nicotine replacement in young people, continued research in this arena might also be a useful focus for future work.

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.
