Secondhand smoke exposure and other signs of tobacco consumption at outdoor entrances of primary schools in 11 European countries

IntroductionAlthough smoking restrictions at child-related settings are progressively being adopted, school outdoor entrances are neglected in most smoke-free policies across Europe. ObjectivesTo describe secondhand smoke (SHS) exposure and tobacco-related signs in outdoor entrances of primary schools in Europe according to area-level socioeconomic status (SES), smoke-free policy, national smoking prevalence, and geographical region. MethodsIn this cross-sectional study we monitored vapor-phase nicotine concentrations at 220 school outdoor entrances in 11 European countries (March 2017–October 2018). To account for nicotine presence, we used the laboratory's limit of quantification of 0.06 μg/m3 as point threshold. We also recorded the presence of smell of smoke, people smoking, cigarette butts, and ashtrays. Half of the schools were in deprived areas. We grouped countries according to their Tobacco Control Scale (TCS) score, smoking prevalence (2017–2018), and United Nations M49 geographical region. ResultsThere were detectable levels of nicotine in 45.9% of the outdoor entrances, in 29.1% smell of smoke, in 43.2% people smoking, in 75.0% discarded butts, and in 14.6% ashtrays. Median nicotine concentration was below the laboratory's limit of quantification <0.06 μg/m3 (Interquartile range:<0.06–0.119). We found higher SHS levels in countries with lower TCS scores, higher national smoking prevalence, and in the Southern and Eastern European regions. People smoking were more common in schools from lower area-level SES and in countries with lower TCS scores (p<0.05). ConclusionsSmoking at school outdoor entrances is a source of SHS exposure in Europe. These findings support the extension of smoking bans with a clear perimeter to the outdoor entrances of schools.

Prevalence of smoking among Chilean older people

Smoking is one of the main causes of death among adults worldwide. To characterize smoking among Chilean older people, according to sociodemographic and clinical variables. Secondary analysis of data obtained during the National Health Survey 2009-10, selecting individuals aged 60 years and older. Expansion factors were used due to the complex design of the sample. Prevalence and characteristics of smoking were calculated, according to age, sex, educational level, marital status, healthcare insurance system and comorbidities. Nineteen percent of older people were actual smokers, and 85% of these smokers were aged between 60 and 69 years. Forty-five percent were highly dependent to nicotine and 73% reported their intention to quit smoking. There is a high prevalence of tobacco smoking among Chilean older people. Prevention measures are needed.

Prevalence, Pattern & Risk Factors of Tobacco Smoking among Male Adult Population of Hayatabad Peshawar Khyber Pakhtunkhwa Pakistan

Prevalence, Pattern & Risk Factors of Tobacco Smoking among Male Adult Population of Hayatabad Peshawar Khyber Pakhtunkhwa Pakistan

Pattern and quitting of tobacco smoking among Egyptian university students.

University students are at high risk of practicing the smoking habit being exposed to smoking peers and easier cigarette availability. This study aims to explore prevalence, attitude and pattern of tobacco smoking and quitting among Beni-Suef University students. A cross-sectional study was conducted from March to May 2019. A total of 4,599 students were selected by using randomized multi-stage sampling using self-administered questionnaire for data collection. The mean age of students found to be smokers was 20.8 ± 1.42 years. Males: Females' ratio was 2:1 (66 vs.34%). Prevalence of smoking was 17.4%. Students of non-medical and non-health colleges showed a significant high smoking rate (18.8 and 18.3% respectively) than students in health faculties (15.2%); p=0.017. Participants believed that they might smoke because of: peers' pressure (73.3%), stress (71.4%), imitating popular figures (61.7%) and availability of money (60.4%). Regarding smoking provinces; 86.1% did smoke in coffee-shops, 73.1% in university yards and only 16.87% used to smoke at home Regarding the attitudes of smokers and nonsmokers towards smoking; the acceptance of indoor smoking was significantly higher (85.6%) among smokers than non-smokers (6.42%); p=0.0001. Of note; 51.2% of smokers versus 86.3% of non-smokers agreed to ban smoking in public places (P=0.001). Majority of smokers (72.1%) had the desire to stop smoking while (57.8%) tried to stop smoking but failed. Smoking is becoming a habit among university students and initiative of a smoke free environment should be encouraged and subject and method.

The proportion of cancers attributable to social deprivation: A population-based analysis of Australian health data

BackgroundCancer is a major disease burden globally and people who are socioeconomically disadvantaged have a higher incidence of many types of cancer. We investigated the potential to reduce socioeconomic disparities in cancer incidence in Australia by lowering the prevalence of exposure to four modifiable causes: smoking, alcohol, overweight/obesity and physical inactivity. MethodsWe used cancer incidence data from the Australian Cancer Database and risk factor prevalence data from the Australian National Health Survey to estimate the proportions of cancers attributable to the four factors, by area-level socioeconomic disadvantage. For the three risk factors where prevalence was lowest among the least disadvantaged (smoking, overweight/obesity, physical inactivity), we also estimated the potential impact of reducing prevalence in the most disadvantaged areas to that in the least disadvantaged areas. ResultsThe proportion of cancer attributable to the four factors in combination ranged from 22 % in the most disadvantaged areas to 14 % in the least disadvantaged areas. If the prevalence of tobacco smoking, overweight/obesity and physical inactivity in the more disadvantaged areas were the same as that in the least disadvantaged, an estimated 19,500 cancers (4 % of all cancers diagnosed) could have been prevented in Australia between 2009 and 2013. ConclusionsReducing the prevalence of key causal factors in areas of greater social disadvantage would prevent many cases of cancer. Strategies to achieve this in highly disadvantaged areas are needed.

Prevalence of Smoking among Iranian Adults: Findings of the National STEPs Survey 2016.

Tobacco smoking is one of the most important avoidable causes of mortality from non-communicable diseases (NCDs). This study aimed to report the crude and standardized prevalence of current, ever, and secondhand smoking at national and provincial levels. This study was performed through an analysis of the results of the STEPs survey 2016, which was conducted as a cross-sectional national study. The samples were selected via multistage cluster sampling and they were representative of general population aged ≥18 years in all provinces of Iran. All the data were analyzed via survey analysis while considering population weights. Age-standardized prevalence was also calculated for the Iranian national population in 2016 and the World Health Organization (WHO) Population 2000-2025. A total of 29963 subjects aged ≥18 years from all provinces of Iran, except for Qom, participated in this study. The age standardized prevalence of current tobacco smoking among adult males and females were 24.4% (95% CI: 23.6%-25.1%) and 3.8% (95% CI: 3.5%-4.1%), respectively. Among the participants, the majority of the current smokers were among those aged 45-54 years (14.5%; 95% CI: 13.6%-15.5%). With increase in age, the prevalence of secondhand smoking decreased to 34.8% (95% CI: 33.3%-36.7%) among people aged 18-24 years and to 22·6% (95% CI: 21.0%-24.3%) among subjects over 70 years. The result of the study can be used to inform policy makers about the status of smoking and help them to design policies for setting rules on and limiting the import of cigarettes and their components to the country.

Waterpipe Tobacco Smoking and Associated Risk Factors among Bangladeshi University Students: An Exploratory Pilot Study

Over the past two decades, there has been a global rise in the prevalence of waterpipe tobacco smoking. Waterpipe tobacco smoking involves the inhalation of heated tobacco smoke after passing through water, and it has been associated with an identified dependence effect similar to that found with cigarette smoking. Despite the popularity of waterpipe tobacco among youth (and in particular, university students) in many countries, detailed data of its usage are lacking in Bangladesh. Therefore, the present study was conducted to explore waterpipe tobacco smoking behavior and normative beliefs among university students in Bangladesh and to assess the factors associated with waterpipe tobacco use. A quantitative cross-sectional survey was carried out among 340 Bangladeshi university students (64.4% male; mean age 21.6 years). Among participants, 13.5% reported they had ever smoked tobacco from a waterpipe and 9.4% had it in past 30 days. Among past 30-day users, 72% were categorized as having waterpipe smoking dependence (n = 23). No females in the sample had ever smoked using a waterpipe. Maternal occupation, monthly expenditure, and regular smoking status were major predominant factors associated with waterpipe smoking behavior of the students. The study is of existential value given that there are no prior studies ever carried out in Bangladesh previously. Recommendations are provided based on the study’s findings, particularly in relation to what action is needed from universities in Bangladesh.

Attitudes toward tobacco cessation and lung cancer screening in two South African communities

ABSTRACT Among men in South Africa, the prevalence of tobacco smoking is as high as 33%. Although smoking is responsible for most lung cancer in South Africa, occupational and environmental exposures contribute greatly to risk. We conducted a tobacco and lung cancer screening needs assessment and administered surveys to adults who smoked >100 cigarettes in their lifetime in Johannesburg (urban) and Kimberley (rural). We compared tobacco use, risk exposure, attitudes toward and knowledge of, and receptivity to cessation and screening, by site. Of 324 smokers, nearly 85% of current smokers had a <30 pack-year history of smoking; 58.7% had tried to stop smoking ≥1 time, and 78.9% wanted to quit. Kimberley smokers more often reported being advised by a healthcare provider to stop smoking (56.5% vs. 37.3%, p=0.001) than smokers in Johannesburg but smokers in Johannesburg were more willing to stop smoking if advised by their doctor (72.9% vs. 41.7%, p<0.001). Findings indicate that tobacco smokers in two geographic areas of South Africa are motivated to stop smoking but receive no healthcare support to do so. Developing high risk criteria for lung cancer screening and creating tobacco cessation infrastructure may reduce tobacco use and decrease lung cancer mortality in South Africa.

Exposure to Environmental Tobacco Smoke (ETS) among Employees of Hospitality Venues in the Light of Changes in Anti-Tobacco Legislation in Poland.

Introduction: Numerous studies conducted in Europe and worldwide have indicated that employees of hospitality venues are the most exposed professional group to environmental tobacco smoke (ETS) in the workplace. The purpose of this study was to assess the exposure of employees of hospitality venues to ETS in the light of changes in anti-tobacco legislation in Poland. Materials and methods: The study consisted of two stages. The first stage was conducted in 2010, while the second in 2015. The study was conducted among employees of 300 randomly selected hospitality venues in the city of Łódź (Poland). In total, 2607 questionnaires were analysed. The study used two survey questionnaires created and recommended by the Institute for Global Tobacco Control to study exposure to ETS. Statistical analysis was made with Statistica 13.1 PL (StatSoft, Poland). Results: In the group of all nonsmoking employees, individuals exposed to ETS at work in 2010 accounted for 72.6%; while in 2015 it was 51.8%. Factors affecting exposure to ETS in the workplace included, among others: age, marital status, education, position held, presence of a smoking room on the premises, and noncompliance with the provisions of the anti-tobacco laws. Conclusions: The prevalence of tobacco smoking among employees of hospitality venues decreased in 2010–2015, however, it remained high. More than half of nonsmoking employees were exposed to ETS at work.

The prevention of tobacco smoking and development of skills of healthy life-style in students of professional educational institutions

The purpose of the study is to analyze issues of prevention of smoking among college students and to reveal influence of social environment including influence of healthy lifestyle to development addiction. The study was based on value social model of health. The study covered student survey (n = 495, proportional selection by gender, age, year of study) and standardized interview with youth professionals (n = 21) to analyze in the youth the main motives for smoking, attitudes to healthy lifestyle and preventive social work methods that are implemented in colleges. The comparative analysis of data was carried out in subgroups of smoking and non-smoking students and experts. The results of study demonstrated the unformed negative attitudes to smoking. Among 25% of smoking students and 39% of non-smoking students smoking itself is considered as mean of communication and integration in youth community. Among 45.6% of respondents the exposure to and conformal behavior as reasons for starting smoking were declared. The analysis of results of the study concerning assessing attitude to smoking from the perspective of fashion and social recognition occurred to be unexpected: the number of non-smoking students who assume smoking is fashionable is 17 times higher than the number of smokers who share these beliefs. The comparison of the data permitted to establish possible causes of such a distribution of answers: in everyday life, smokers are faced with various legislative restrictions and social censure, while their non-smoking peers focus on social communicative and recreational effects of this habit. There are particular contradictions in the interpretation by students and youth professionals of causes of smoking. This testifies certain unawareness of professionals about age-related psychological characteristics and emotional conditions of students.

The case for gender considerate tobacco control policies in Albania

BackgroundTobacco use is a serious health concern in Albania. While the prevalence of tobacco smoking has traditionally been higher for men, the increasing prevalence of smoking for women is becoming a concern. The 2007 Tobacco Control policy mandated smoke-free indoor spaces, banned various forms of tobacco advertising, required written health warnings on packaging and levied excise taxes on cigarette sales. Since smoking behavior varies among different demographic groups, each group’s response to a uniform policy will differ, blunting the effectiveness of these efforts as a result. This study examines various socioeconomic, demographic and behavioral factors affecting both the likelihood and frequency of smoking in Albanian households in order to provide insights on targeting various populations more effectively.MethodsThe study utilizes data from Albanian 2008–09 and 2017–18 Demographic and Health Surveys consisting of adults aged 15–49 years. The outcome variable includes respondents’ current tobacco smoking behaviour and its frequency. The exposure variables include respondents’ sociodemographic and lifestyle characteristics. We use a two-level random intercept model with the two-stage residual inclusion estimation method to determine the association between outcome and exposure variables. By including a time variable, we capture the change in smoking behavior during the 2009–2018 period. We also extend the analysis by assessing the differential influence of gender on the likelihood of smoking, both by income quintiles and education.ResultsThe results suggest that the likelihood of smoking decreased by 23% in 2017–18 compared to 2008–09, after controlling for various socioeconomic and demographic factors. Tobacco smoking is also found to be linked to alcohol consumption, with binge drinkers 59% more likely to smoke tobacco compared to moderate drinkers. We also found significant inter-quintile and inter-educational differences in smoking practices within each gender category. While the likelihood of tobacco smoking decreases with increasing wealth and educational attainment among men, the opposite (for wealth) or more involved (for educational attainment) patterns are true among women.ConclusionsTo further enhance the effectiveness of the current Tobacco Control policy, the Government of Albania should target various demographic groups (such as poor males, rich and educated females) in a differentiated fashion.

Cancer incidence attributable to tobacco smoking in GCC countries in 2018.

INTRODUCTIONThe Gulf Cooperation Council (GCC) member countries include Bahrain, Kuwait, Oman, Qatar, Saudi Arabia, and United Arab Emirates. The current study aims to provide an estimate of the population fractions of cancer cases attributable to tobacco smoking in the GCC countries.METHODSPopulation attributable fraction (PAF) was calculated for cancers that were listed by the International Agency for Research on Cancer (IARC) to have sufficient evidence of causal association. The estimated number of incident cancer cases in GCC countries were retrieved from the IARC GLOBOCAN database. The prevalence estimates of current tobacco smoking among persons aged ≥15 years were obtained from the World Health Organization report on prevalence of tobacco smoking. Relative risk estimates for various cancers were obtained from published meta-analyses. Summary PAFs and cancer cases attributable to tobacco smoking are reported by country, sex, and cancer type.RESULTSTobacco smoking was responsible for 2536 (16.3%) of cancer cases in GCC countries in 2018. It accounted for 22.8% (n=2396) and 2.8% (n=140) of cancer cases among males and females, respectively. Among males, the highest number of cancer incident cases attributable to smoking was lung cancer (807) followed by urinary bladder (328), and colorectal cancer (305). Among females, the highest number of cancer cases attributable to smoking was lung cancer (62) followed by lip and oral cavity (13), and cervical cancer (13).CONCLUSIONSTobacco smoking accounted for a large portion of cancer cases attributable to preventable risk factors in GCC countries. Preventive efforts focusing on reducing tobacco smoking should be a high priority in GCC countries.

Enhancing the Immune Response of a Nicotine Vaccine with Synthetic Small "Non-Natural" Peptides.

The addictive nature of nicotine is likely the most significant reason for the continued prevalence of tobacco smoking despite the widespread reports of its negative health effects. Nicotine vaccines are an alternative to the currently available smoking cessation treatments, which have limited efficacy. However, the nicotine hapten is non-immunogenic, and successful vaccine formulations to treat nicotine addiction require both effective adjuvants and delivery systems. The immunomodulatory properties of short, non-natural peptide sequences not found in human systems and their ability to improve vaccine efficacy continue to be reported. The aim of this study was to determine if small “non-natural peptides,” as part of a conjugate nicotine vaccine, could improve immune responses. Four peptides were synthesized via solid phase methodology, purified, and characterized. Ex vivo plasma stability studies using RP-HPLC confirmed that the peptides were not subject to proteolytic degradation. The peptides were formulated into conjugate nicotine vaccine candidates along with a bacterial derived adjuvant vaccine delivery system and chitosan as a stabilizing compound. Formulations were tested in vitro in a dendritic cell line to determine the combination that would elicit the greatest 1L-1β response using ELISAs. Three of the peptides were able to enhance the cytokine response above that induced by the adjuvant delivery system alone. In vivo vaccination studies in BALB/c mice demonstrated that the best immune response, as measured by nicotine-specific antibody levels, was elicited from the conjugate vaccine structure, which included the peptide, as well as the other components. Isotype analyses highlighted that the peptide was able to shift immune response toward being more humorally dominant. Overall, the results have implications for the use of non-natural peptides as adjuvants not only for the development of a nicotine vaccine but also for use with other addictive substances and conventional vaccination targets as well.

Fight against smoking as a factor of healthy lifestyle

The article analyzes the impact of lifestyle, tobacco smoking in particular, on health and life expectancy. Using the latest statistics, the author examines the problem of tobacco smoking in Russia and the world, describes the impact of this harmful habit not only on the health of the population, but also on the environment and the economy. The paper provides a brief history of tobacco control, describes modern anti-tobacco measures taken by the world community under the auspices of the World Health Organization (WHO).Special attention is paid to the state of public opinion on issues related to the prevalence of tobacco smoking in Russia, its impact on the health and life expectancy of the population, the motivation of the population to abandon this habit and the impact on its presence / absence in social environment. It addresses the problem of child and adolescent smoking, analyzes the degree of parental influence and the likelihood that the child, in consequence, will become a regular smoker.The author deals with the problem of passive smoking and the impact of secondary smoke on the health of children and adults, and notes that the anti-tobacco law adopted in Russia in 2013 undoubtedly reduced the number of passive smokers, which had beneficial effect on public health.The work touches upon the currently relevant issue of Electronic Nicotine Delivery Systems (ENDS), provides usage statistics, and also raises the question of the consequences of the increasing popularity of ENDS.The empirical base of the work is the data of WHO, the Federal State Statistics Service, the American Cancer Society, as well as studies of the Department of Sociology of Family and Demography (Faculty of Sociology, Lomonosov Moscow State University), the Public Opinion Foundation and the All-Russian Public Opinion Research Center.This article will be of interest to specialists in the field of sociology of medicine, as well as to a wide circle of readers interested in the issues of addictive behavior and the formation of a healthy lifestyle.

Nose-Only Water-Pipe Smoke Exposure in Mice Elicits Renal Histopathological Alterations, Inflammation, Oxidative Stress, DNA Damage, and Apoptosis.

The prevalence of water-pipe tobacco smoking is increasing worldwide, and is relatively high among youth and young adults. Exposure to water-pipe smoke (WPS) has been reported to affect various systems including the respiratory, cardiovascular and reproductive systems. However, the impact of WPS exposure on the kidney has received only scant attention. Here, we assessed the effect of nose-only WPS exposure for one or four consecutive weeks on renal histology, inflammation, oxidative stress, DNA damage, and apoptosis. The duration of the session was 30 min/day and 5 days/week. Control mice were exposed to air. Light and electron microcopy analysis revealed that the WPS exposure (especially at 4-week time point) caused degeneration of the endothelial cells of the glomerular capillaries and vacuolar degenerations of the proximal convoluted tubules. WPS exposure also significantly decreased the creatinine clearance, and significantly increased proteinuria and urinary kidney injury molecule-1 (KIM-1) concentration. Kidney lipid peroxidation, reactive oxygen species, and oxidized glutathione were significantly increased. WPS exposure also affected the concentration of reduced glutathione and the activity of catalase. Likewise, renal concentrations of interleukin (IL)-6, IL-1β and KIM-1 were augmented by WPS exposure. Moreover, WPS caused DNA damage as evaluated by comet assay, and increased the expression of cleaved caspase-3 and cytochrome C in the kidney. We conclude that exposure of mice to WPS caused renal histopathological alterations, inflammation, oxidative stress, DNA damage, and apoptosis. If the latter findings could be substantiated by controlled human studies, it would be an additional cause for disquiet about an established public health concern.

Maternal smoking and cannabis use during pregnancy and infant outcomes.

Background Our aim was to determine the prevalence of tobacco smoking and e-cigarettes and cannabis use during pregnancy, whether these were influenced by ethnicity, and their relationship to perinatal outcomes. Methods A study was carried out in 4465 infants whose mothers delivered during 2017 and 2018. Self-reported maternal smoking, e-cigarette and cannabis use at booking were recorded. Outcome measures were birthweight and head circumference z-scores and admission to the neonatal intensive care unit (NICU). Results Two hundred and five women reported smoking cigarettes (4.7%), five were using e-cigarettes (0.11%) and 106 were using cannabis (2.43%). Women were most likely to smoke if young (15-19 years old) or from a mixed-race or White background. Cigarette smoking was associated with a lower mean z-score for birthweight (-0.587 vs. -0.064) and head circumference (-0.782 vs. -0.157) (both outcomes P < 0.0001). Young, mixed-race women were most likely to be both smoking and using cannabis during pregnancy and their infants had a lower birthweight mean z score (-0.989 vs. -0.587, P = 0.028) and head circumference z score (-1.33 vs. 0.782, P = 0.025) than cigarette use alone. Conclusion Young, mixed-race women were most likely to be both smoking and using cannabis during pregnancy and should be targeted for cessation programmes.

Smoking prevalence in the Eastern Mediterranean Region.

Three global reports issued by the World Health Organization (WHO) track and report on trends in the prevalence of tobacco smoking from 2000 to 2025 based on data from national surveys. This review aimed to compare regional and country-level projections for current tobacco smoking as presented in the WHO trend reports. These changes were considered in the context of improved monitoring and tobacco control policies. Regional and country-level results in the WHO trend reports were considered in terms of the projected percentage point increase of current tobacco smoking between 2000 and 2025. Data on national surveys and policy implementation came from the relevant WHO reports. In the 2019 trend report, the prevalence of current tobacco smoking among males is projected to decrease by less than 2 percentage points by 2025. Eight countries featured in both the 2015 and 2019 WHO trend reports. Seven of these countries indicated a more encouraging projection (a decline in their projected increase between 2000 and 2025) for current male tobacco smoking in the 2019 report than in the 2015 report. For five out of these seven countries, their monitoring and tobacco control policy implementation improved over the same period. Countries in the Region should implement additional national surveys to improve the accuracy of prevalence estimates, allow further projections to be performed and motivate policy-makers to make positive policy changes. Solutions to under-reporting biases during surveys should be considered. Governments should use trend projections to guide effective tobacco control policies to reduce tobacco use in the Region.

Tobacco use and its associated factors among older people: a community-based study in Egypt.

Smoking is a major health risk and tobacco use is common in all age groups in Egypt. In older people, tobacco use is considered the primary preventable cause of disability and death. Few studies have considered tobacco use in older people and its associated factors. This study aimed to estimate the prevalence and type of tobacco use among older people in Mansoura, Egypt. A cross-sectional descriptive population-based study was carried out in Mansoura District (both urban and rural areas). It included 663 older people aged 60 years or over. Data were collected from interviews at participants' homes using a questionnaire covering family sociodemographic details, tobacco smoking history, nicotine addiction scale, and religious commitment inventory. The prevalence of active current tobacco smoking among participants was 25.3%, passive smoking was 37.1%, while 6.3% were ex-smokers. Among active current smokers nicotine dependence was 42.3%, and 23.3% had failed to quit smoking, while 30.3% had the intention to quit. Logistic regression analysis revealed that being male, having low levels of education and religiosity, and urban residence were the independent predictors of current smoking. The prevalence of both active and passive tobacco smoking among older people was considered high compared to high-income countries. The most important factors associated with smoking status were sex, education and religiosity. There is an urgent need for anti-tobacco campaigns and smoking cessation interventions specifically targeting older people.

Change in Compliance of Staff at 4 Vietnam Universities after the Enactment of Smoke-free Environment Decree.

Background:The Tobacco Control Law in Vietnam was adopted in 2012 and came into force from May 2013, followed by a number of guiding sub-law legal documents. Smoke-free campus policy in university is considered an important measure to protect people from secondhand smoking as well as staffs and students will be in favour of the policy. Furthermore, there has been evidence suggested that smoke-free policy had positive impact on active smoking as well as anti-smoking attitude.Methods:A cross-sectional self-administered study of staff at 4 universities were conducted in 2 phases, Phase 1 as early introduction of the Law (n = 900) and Phase 2 as 1-year post (n = 885). Demographics, tobacco consumption, compliance status and compliance with awareness towards the campus smoking regulations were assessed in both phases.Results:Daily smoking prevalence decreased significantly (P < .05) 1 year after implementing the smoke-free policy, while a significant increase in occasional smoking (P < .01). Compliance of staff to the regulation the campus should be indoor smoke-free was significantly increase at Phase 2 compared to Phase 1, however participants reported there would be places on campus that smokers frequently violated the smoke-free regulations.Conclusions:The study indicated a significant positive change in compliance of staff at the 4 universities after the implementation of the Tobacco Control Law, included the smoke-free policy. Although the prevalence of tobacco smoking in this study was low, the proportion of respondents who reported to reduce infringement the smoke-free policy suggests support for staff smokers would be beneficial. Raising awareness and enforcement is likely to enhance the long-term outcomes of the implementation of smoke-free environment.
