Smoke-free homes and smoking cessation and relapse in a longitudinal population of adults.

INTRODUCTION: The present study reports on the prevalence of smoke-free homes, the characteristics of participants who adopted a smoke-free home policy, and the association between smoke-free homes and subsequent predictors of smoking cessation. METHODS: Data are reported on 4,963 individuals who originally participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed follow-up surveys in 2001 and 2005. The relationship between home smoking policy and smoking behavior was examined with a multivariate regression model. RESULTS: Among those who were smokers at the 2001 follow-up, the percentage reporting that no smoking was allowed in their home increased from 29% in 2001 to 38% in 2005. Smokers most likely to adopt smoke-free home policies between 2001 and 2005 were males, former smokers, and those who had lower levels of daily cigarette consumption (among those who continued to smoke), those with higher annual household incomes, and those with no other smokers in the household. Some 28% of smokers with smoke-free homes in 2001 reported that they had quit smoking by 2005 compared with 16% of those who allowed smoking in their homes (odds ratio [OR] = 1.7, 95% CI = 1.4-2.2), and baseline quitters with smoke-free homes also were less likely to relapse (OR = 0.6, 95% CI = 0.4-0.8). DISCUSSION: Smoke-free homes are becoming more prevalent, and they are a powerful tool not only to help smokers stop smoking but also to help keep those who quit from relapsing back to smoking.

Secondhand smoke and particulate matter exposure in the home.

With the increasing normative trend of clean indoor air laws prohibiting smoking in public places such as worksites and restaurants, the home is becoming the primary source of secondhand smoke (SHS) exposure. However, little empirical data indicate how SHS is distributed throughout homes and whether smoking in segregated areas offers protection. This project studied real-time data on levels of SHS in 9 homes in which smoking was permitted and in 3 smoke-free homes. Active sampling monitors were used to assess levels of PM(2.5), a marker for SHS, over a 3-day period. In smoking homes, one monitor was placed in the primary smoking area and another in a distal location, where smoking generally did not occur. Participants logged smoking and other activities that could affect air quality. In smoking homes, without assuming normality, the mean PM(2.5) level for the primary smoking areas was statistically significantly higher than that for distal areas (84 and 63 microg/m3, respectively). Both levels far surpassed the U.S. Environmental Protection Agency's annual standard of 15 microg/m3 for outdoor air quality. By contrast, the smoke-free home mean was 9 microg/m3, similar to outdoor air quality. These results suggest that the air in smoking homes was several times more polluted than that in smoke-free homes, regardless of where the measurements were taken, meaning that efforts to confine smoking to only part of the home offer no protection for people anywhere inside the home. Household members can be protected by implementing a smoke-free home policy.

Attitudes and beliefs about secondhand smoke and smoke-free policies in four countries: findings from the International Tobacco Control Four Country Survey.

INTRODUCTION: This paper describes the varying levels of smoking policies in nationally representative samples of smokers in four countries and examines how these policies are associated with changes in attitudes and beliefs about secondhand smoke over time. METHODS: We report data on 5,788 respondents to Wave 1 of the International Tobacco Control Four Country Survey who were employed at the time of the survey. A cohort of these respondents was followed up with two additional survey waves approximately 12 months apart. Respondents' attitudes and beliefs about secondhand smoke as well as self-reported policies in their workplace and in bars and restaurants in their community were assessed at all waves. RESULTS: The level of comprehensive smoke-free policies in workplaces, restaurants, and bars increased over the study period for all countries combined and was highest in Canada (30%) and lowest in the United Kingdom (0%) in 2004. In both cross-sectional and longitudinal analyses, stronger secondhand smoke policies were associated with more favorable attitudes and support for comprehensive regulations. The associations were the strongest for smokers who reported comprehensive policies in restaurants, bars, and their workplace for all three survey waves. DISCUSSION: Comprehensive smoke-free policies are increasing over time, and stronger policies and the public education opportunities surrounding their passage are associated with more favorable attitudes toward secondhand smoke regulations. The implication for policy makers is that, although the initial debate over smoke-free policies may be tumultuous, once people understand the rationale for implementing smoke-free policies and experience their benefits, public support increases even among smokers, and compliance with smoke-free regulations increases over time.

Longitudinal evaluation of smoke-free Scotland on pub and home drinking behavior: findings from the International Tobacco Control Policy Evaluation Project.

INTRODUCTION: On 26 March 2006, Scotland implemented a smoke-free policy prohibiting smoking in indoor public venues, including bars and pubs. Drinking and smoking are highly associated behaviors, so we evaluated whether the regulations would decrease drinking behavior among smokers in public venues. We further assessed whether this effect would be more pronounced in heavier drinkers and whether decreases in drinking behavior in pubs would be offset by increased drinking in the home. METHODS: Participants (N = 1,059) were adult smokers and nonsmokers from Scotland and from the rest of the United Kingdom, which did not have comprehensive smoke-free policies during the study period. Data were collected using a random-digit-dialed telephone survey from February to March 2006, just prior to the policy implementation in Scotland. Follow-up surveys were conducted in March 2007. Using baseline data, we categorized participants as abstainers, moderate drinkers, or heavy drinkers. RESULTS: Overall, results demonstrated that drinking behavior did not change significantly in Scotland compared with the rest of the United Kingdom following implementation of the smoke-free policy in Scotland. However, planned comparisons examining mean changes in drinks consumed in pubs or bars following the legislation demonstrated that the smoke-free legislation was associated with reduced drinking behavior in pubs and bars among moderate- and heavy-drinking smokers in Scotland. These moderate- and heavy-drinking Scottish smokers also reduced their pub attendance following policy implementation. DISCUSSION: The smoke-free Scottish law did not increase drinking in the home. These findings suggest that smoke-free policies may have additional public health benefits for those at greater risk for alcohol-related health problems.

The impact of smokefree legislation in Scotland: results from the Scottish ITC: Scotland/UK longitudinal surveys.

BACKGROUND: To evaluate how Scotland's smokefree law impacted self-reported secondhand smoke (SHS) exposure in hospitality venues, workplaces and in people's homes. In addition, we examine changes in support for the law, pub and restaurant patronage, smoking cessation indicators and whether any observed changes varied by socioeconomic status. METHODS: A quasi-experimental longitudinal telephone survey of nationally representative samples of smokers and non-smokers interviewed before the Scottish law (February to March 2006) and 1 year later after the law (March 2007) in Scotland (n = 705 smokers and n = 417 non-smokers) and the rest of the UK (n = 1027 smokers and n = 447 non-smokers) where smoking in public places was not regulated at the time. RESULTS: Dramatic declines in the observance of smoking in pubs, restaurants and workplaces were found in Scotland relative to the rest of the UK. The change in the percent of smokers reporting a smokefree home and number of cigarettes smoked inside the home in the evening was comparable in Scotland and the rest of the UK. Support for smokefree policies increased to a greater extent in Scotland than in the rest of the UK. Self-reported frequency of going to pubs and restaurants was generally comparable between Scotland and the rest of the UK; however, non-smokers in Scotland were more likely to frequent pubs more often. No differences in smoking cessation indicators were observed between countries. CONCLUSION: The Scottish smokefree law has been successful in decreasing secondhand smoke exposure while causing none of the hypothesized negative outcomes.

Perceived effectiveness of tobacco countermarketing advertisements among young adults.

OBJECTIVES: To measure relative effectiveness of tobacco countermarketing advertisements by category and emotive execution style among young adults. METHODS: Participants (n=1011) from 2 US 4-year colleges, one southern and one northern were surveyed before and after viewing advertisements in one of 3 categories: social norms, health consequences, or tobacco industry manipulation and with 4 emotive execution styles: drama, testimonial (negative emotive) and humor, sarcasm (positive). RESULTS: Health consequences and negative emotive advertisements were rated significantly most persuasive. CONCLUSIONS: This is the first study to support the effectiveness of tobacco countermarketing advertisements emphasizing the negative emotive health consequences of smoking among young adults.

The role of public policies in reducing smoking prevalence in California: results from the California tobacco policy simulation model.

Tobacco control policies are examined utilizing a simulation model for California, the state with the longest running comprehensive program. We assess the impact of the California Tobacco Control Program (CTCP) and surrounding price changes on smoking prevalence and smoking-attributable deaths. Modeling begins in 1988 and progresses chronologically to 2004, and considers four types of policies (taxes, mass media, clean air laws, and youth access policies) independently and as a package. The model is validated against existing smoking prevalence estimates. The difference in trends between predicted smoking rates from the model and other commonly used estimates of smoking prevalence for the overall period were generally small. The model also predicted some important changes in trend, which occurred with changes in policy. The California SimSmoke model estimates that tobacco control policies reduced smoking rates in California by an additional 25% relative to the level that they would have been if policies were kept at their 1988 level. By 2004, the model attributes 59% of the reduction to price increases, 28% of the overall effect to media policies, 11% to clean air laws, and only a small percent to youth access policies. The model estimates that over 5000 lives will be saved in the year 2010 alone as a result of the CTCP and industry-initiated price increases, and that over 50,000 lives were saved over the period 1988-2010. Tobacco control policies implemented as comprehensive tobacco control strategies have significantly impacted smoking rates. Further tax increases should lead to additional lives saved, and additional policies may result in further impacts on smoking rates, and consequently on smoking-attributable health outcomes in the population.

[Global air monitoring study: a multi-country comparison of levels of indoor air pollution in different workplaces results from Tunisia]. / Etude mondiale sur le monitorage de l'air comparaison des niveaux de pollution de l'air dans differents lieux publics: cas de la Tunisie.

BACKGROUND: In 1986, a report of the U.S. Surgeon General concluded that second hand smoke is a cause of disease in healthy non smokers. Subsequent many nations including Tunisia implement smoke-free worksite regulations. The aim of our study is to test air quality in indoor ambient air venues in Tunisia. METHODS: A TSI SidePak AM510 Personal Aerosol Monitor was used to sample, record the levels of respirable suspended particles (RSP) in the air and to assess the real-time concentration of particles less than 2.5 microm in micrograms per cubic meter, or PM2.5. Thirty three venues were sampled in Tunis. The venues were selected to get a broad range of size, location and type of venue. Venues included restaurants and cafés, bars, bus stations, hospitals, offices, and universities. RESULTS: The mean level of indoor air pollution was 296 microg/m3 ranged from 11 microg/m3 to 1,499 microg/m3. The level of indoor air pollution was 85% lower in venues that were smoke-free compared to venues where smoking was observed (p<0.001). Averaged across each type of venue, the lowest levels of indoor air pollution were found in hospitals, offices and universities (52 microg/m3) and the highest level was found in a bar (1,499 micro/m3). CONCLUSION: Hospitality venues allowing indoor air smoking in Tunisia are significantly more polluted than both indoor smoke-free sites and outdoor air in Tunisia. This study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public worksites dramatically reduce second hand smoke exposure and improve worker and patron health.

Secondhand smoke and indoor public spaces in Paducah, Kentucky.

INTRODUCTION: Secondhand smoke (SHS) is the third leading cause of preventable death in the United States. It is responsible for an estimated 3,000 lung cancer deaths annually in never-smokers in the US. It also accounts for over 35,000 deaths annually from coronary heart disease in never-smokers. It increases the number and severity of asthmatic attacks in over 300,000 asthmatic children each year, and is associated with Sudden Infant Death Syndrome and middle ear infections, in addition to other illnesses in children. The purpose of this study was to examine indoor air quality in a sample of hospitality venues in Paducah, Kentucky. The relation between indoor air pollution and the presence of on premises smoking was assessed. METHODS: A Personal Aerosol Monitor was used to sample and record the levels of respirable suspended particles in the air. The SidePak uses a built-in sampling pump that draws air through the device and the particulate matter in the air scatters the light from a laser. Based on this light scattering, the device determines to assess the real-time concentration of particles smaller than 2.5 microm in micrograms per cubic meter, or PM2.5. RESULTS: The average PM2.5 concentration in the eleven locations sampled in Paducah, Kentucky, was 177 microg/m3. The average fine particle pollution level in the non-smoking sections tested was 87 microg/m3, which is 29 times higher than the average fine particle pollution level in smoke-free air or 6 times higher than outdoor air in Paducah. The average PM2.5 level across all nine smoking-permitted hospitality locations sampled in Paducah was 200 microg/m3. For a full-time employee in the venues sampled in this study, the average annual PM2.5 exposure would be 46 microg/m3 (assuming exposure to 200 microg/m3 on the job, exposure to zero particles off the job, and a 40-hour work week). The EPA average annual PM2.5 limit is exceeded by 3.1 times due solely to occupational exposure. Of the ten locations visited that permit indoor smoking, the air monitoring was done in the non-smoking section of six of them. These locations included five restaurants and one public government office. The average fine particle pollution level in these non-smoking sections was 87 microg/m3, which is 29 times higher than the average fine particle pollution level in smoke-free air or 6 times higher than outdoor air in Paducah. It is also interesting to note that the average fine particle pollution level in the smoking section of one restaurant was actually less than the average fine particle pollution level in the "no smoking" section of two other restaurants. CONCLUSIONS: The effects of secondhand smoke are substantial and rapid, explaining the relatively large health risks associated with secondhand smoke exposure that have been reported in epidemiological studies. This study shows that physically separating smokers and non-smokers is not an effective way to protect non-smoking patrons from tobacco smoke pollution. "No smoking" sections provided protection to nonsmokers that can be characterized as trivial at best. In fact, patrons in Paducah cannot be certain that their exposure will not be higher in the "no smoking" sections of certain venues when compared to the smoking sections of other venues. It is imperative that physicians and other healthcare providers actively and aggressively lobby local policymakers to pass regulatory and/or public health ordinances, which have been demonstrated to be effective in controlling exposure to secondhand smoke.

Global air monitoring study: a multi-country comparison of levels of indoor air pollution in different workplaces.

INTRODUCTION: A local study completed in Singapore, which was part of an international multi-country study that aims to develop a global assessment of exposure to second-hand smoke in indoor workplaces, gathered data regarding the indoor air quality of public areas. It was hypothesised that air would be less polluted in non-smoking venues compared to places where smoking occurred. MATERIALS AND METHODS: A TSI SidePak AM510 Personal Aerosol Monitor was used to sample and record the levels of respirable suspended particles (RSP) in the air. A broad range of venues were sampled in Singapore. The primary goal of data analysis was to assess the difference in the average levels of RSP in smoke-free and non smoke-free venues. Data was assessed at 3 levels: (a) the mean RSP across all venues sampled compared with the mean levels of smoke-free and non smoke-free venues, (b) levels in venues where smoking occurred compared with similar venues in Ireland, and (c) comparison between smoke-free and non smoke-free areas according to the type of venue. Statistical significance was assessed using the Mann-Whitney U-test. RESULTS: The level of indoor air pollution was 96% lower in smoke-free venues compared to non smoke-free venues. Averaged across each type of venue, the lowest levels of indoor air pollution were found in restaurants (17 microg/m3) and the highest in bars (622 microg/m3); both well above the US EPA Air Quality Index hazardous level of >or=251 ug/m3. CONCLUSIONS: This study demonstrates that workers and patrons are exposed to harmful levels of a known carcinogen and toxin. Policies that prohibit smoking in public areas dramatically reduce exposure and improve worker and patron health.

Does smoke-free Ireland have more smoking inside the home and less in pubs than the United Kingdom? Findings from the international tobacco control policy evaluation project.

BACKGROUND: In March 2004, Ireland implemented comprehensive smoke-free regulations. Some were concerned this would cause pub patrons to move their smoking and drinking from inside pubs to inside homes. This article aims to assess whether nationwide smoke-free policies are associated with more smoking or drinking inside the home. METHODS: Participants were 1917 adult smokers (> 18-years old) from Ireland (n = 582), Scotland (n = 507) and the rest of the United Kingdom (n = 828), which did not have smoke-free laws at the time of the interview, who completed a random digit-dialed telephone survey in February to March 2006. The percentage of alcoholic drinks consumed in the home versus pubs was compared by country as well as the percentage of daily cigarette consumption occurring in the home after work. RESULTS: Irish respondents reported a significantly lower percentage of alcoholic drinks consumed in the home compared to Scotland and the rest of the United Kingdom, and cigarette consumption in the home was comparable in all three regions. CONCLUSIONS: Smoking and drinking in the home was not greater in smoke-free Ireland than in the United Kingdom, where there was not a smoke-free law at the time of the survey. These findings add further support to the enactment of comprehensive smoke-free laws, as called for in the Framework Convention on Tobacco Control.

Internet cigarette purchasing among 9th grade students in western New York: 2000-2001 vs. 2004-2005.

OBJECTIVE: To assess trends and correlates of youth cigarette purchasing behavior on the Internet. METHODS: In 2000-2001, Roswell Park Cancer Institute conducted a survey asking 7,019 ninth grade students in Erie and Niagara Counties in New York State about their tobacco use and purchasing habits, including use of the Internet to buy cigarettes. The 2004-2005 survey is a replication of the 2000-2001 survey. Both surveys used an anonymous, self-administered questionnaire survey. These data were combined in order to examine trends in youth smoking behavior. RESULTS: Students surveyed in 2004-2005 were 2.6 times more likely (95% CI: 1.5, 4.6) to have purchased cigarettes over the Internet in the 30 days prior to the survey than those surveyed in 2001 (5.2% to 1.6%); however, the intention to use the Internet as a cigarette source in the future did not change between survey periods. CONCLUSION: Youth online cigarette purchasing has increased but intention to use the Internet to purchase cigarettes in the future has remained the same, suggesting that this trend may be reaching a plateau. Recent public efforts to reduce online cigarette sales will need to be evaluated in order to determine which policy or combination of policies are most effective.

Anti-tobacco television advertising and indicators of smoking cessation in adults: a cohort study.

The objective of this study was to assess the relationship between exposure to state-sponsored anti-tobacco advertising and smoking cessation. Cessation rates in 2001 among a cohort of 2061 smokers who participated in the Community Intervention Trial for Smoking Cessation between 1988 and 1993 and completed a follow-up survey in 2001 were merged with 2000-01 television advertising exposure data from Nielsen Media Research. The relative risk for quitting was estimated to be 10% higher for every 5000 units of exposure to state anti-tobacco television advertising over the 2-year period, although this did not quite achieve statistical significance. The association was even larger among those who reported that the level of information in the media about the dangers of smoking had increased 'a lot' between 1993 and 2001 (RR = 1.19, 95% CI = 1.03-1.38). These data are consistent with the finding that increased exposure to state anti-tobacco media increases smoking cessation rates.

Concurrent quit & win and nicotine replacement therapy voucher giveaway programs: participant characteristics and predictors of smoking abstinence.

This study compares the participant characteristics, program costs, and outcomes of a Quit & Win contest and a nicotine replacement therapy (NRT) voucher giveaway promotion. Both programs were conducted simultaneously so that smokers could enroll in either one program alone (n = 849 and 690, respectively) or both programs (Combination group; n = 230). A follow-up telephone survey of a random sample of participants was conducted 4 to 7 months after enrollment to evaluate smoking status. At enrollment, participants in the three groups were comparable on most smoking and demographic variables, although Quit & Win participants were, on average, younger than those who signed up to get the NRT voucher. Compared with the characteristics of smokers in the region, those who enrolled in the intervention programs were heavier smokers and had more years of formal education. At follow-up, the self-reported quit rates were similar across the three intervention groups, ranging between 25 percent and 30 percent. The only evidence for a higher quit rate among those in the Combination group was among younger smokers. On a simple estimated cost per quit basis, the Quit & Win (130 dollars) and NRT (179 dollars) voucher interventions appear roughly comparable. In all groups, abstinence rates were higher among lighter smokers (<21 cigarettes per day), participants who did not live with another smoker, and those who were married. Both the Quit & Win and NRT voucher giveaway programs were effective in recruiting smokers to make a quit attempt, although combining both interventions did not generally increase abstinence rates.

Global air monitoring study: a multi-country comparison of levels of indoor air pollution in different workplaces. Results from Romania, May 2006.

Second hand smoking is still a great challenge in every country. Every tobacco transnational companies try to destroy all the evidence of the consequences of this kind of exposure. Now in many countries there are surveillance studies looking for evidence. One of this study (organized in 20 countries) is this one where Romania was counterpart. We tested with the TSI SidePak AM510 Personal Aerosol Monitor the level of exposure in 41 pubs, restaurants and bars and the results demonstrate that there are high level of particles coming from active smoking. In the same time the authors are making a comparison of different levels form other countries where this kind of monitor was used.

Disparity in the use of smoking cessation pharmacotherapy among Medicaid and general population smokers.

BACKGROUND: The prevalence of smoking remains higher among the Medicaid population compared with the general population. To reduce this disparity, the majority of state Medicaid programs now provide coverage for smoking cessation pharmacotherapy. The objectives of this study were to (1) assess awareness of this benefit among Medicaid smokers and (2) compare the use of pharmacotherapy among a sample of Medicaid smokers with smokers in the general population of western New York. METHODS: This report summarizes findings from two cross-sectional studies conducted in western New York State during 2002 to 2003: (1) Medicaid smokers (n = 1,174) completed an interviewer-administered questionnaire in the Office of Medicaid Management and (2) smokers from the general population (n = 852) completed a telephone survey. RESULTS: The majority of Medicaid smokers (54%) remain unaware of the program benefit providing coverage for smoking cessation pharmacotherapies. Medicaid smokers were much less likely (odds ratio = 0.33, 95% confidence interval = 0.25-0.44) than the general population to report having ever used pharmacotherapies. CONCLUSIONS: Highlighting the availability of the smoking cessation pharmacotherapy benefit to Medicaid program participants may be one strategy to enhance quit attempts among this population. Future research should identify other potential barriers to the use of effective pharmacotherapies among poorer smokers.

Access to low-taxed cigarettes deters smoking cessation attempts.

We examined whether smokers who purchased low-taxed cigarettes from American Indian reservations had lower quit attempt and cessation rates than did smokers who purchased cigarettes from full-price outlets. Smokers who bought cigarettes from American Indian reservations were half as likely to make a quit attempt and had a nonsignificant trend toward lower cessation rates (20% vs 10%) compared with those who bought full-priced cigarettes. Interventions that reduce price differentials are suggested to maximize the public health benefit of cigarette excise taxes.

Perceptions about cigarette smoking and risks among college students.

The objective of the present study was to describe how college students perceive the risks of cigarette smoking and addiction to nicotine. Data came from a self-administered survey of 1,020 college students enrolled in two 4-year liberal arts colleges in the United States. The survey was conducted in the fall of 2001. Smokers and nonsmokers differed markedly in their perceptions about the health risks associated with short-term exposure to smoking. College students in this sample who smoked did not fully comprehend the risks associated with smoking. Smokers were half as likely as nonsmokers to believe that there are health risks from smoking only on weekends or a couple of days a week. Anti-tobacco messages for young adult smokers need to communicate more effectively the concept that each cigarette they smoke is doing them damage.

Cigarette purchasing behaviors when prices are high.

The objective of this study was to assess the cigarette purchase patterns of smokers in Erie and Niagara Counties following recent increases in the state excise tax for cigarettes. Data were collected with telephone interviews of a sample of 1,548 randomly selected people in Erie and Niagara Counties between October 2002 and March 2003. Purchase patterns were assessed for the 908 smokers in the sample who responded to questions about cigarette purchasing patterns. Thirty-three percent reported that their usual source of cigarettes is from a small store, large store, pharmacy, or vending machine, while 67% reported that their usual source is from an Indian reservation. Only one smoker reported the Internet was a usual source of cigarettes. The average price paid per pack was $4.80 in a small store and $1.91 on an Indian reservation. Price influences smoking behavior; however, the majority of smokers are taking advantage of readily available venues where less expensive, untaxed cigarettes are sold. This may undermine the public health benefit of higher prices and cause lost revenue to state and local governments.
