In recent years there has been a heightened public concern over the potentially harmful effects of environmental tobacco smoke (ETS). In response, smoking has been banned on many jobs. Using data from the 1991 and 1993 National Health Interview Survey and smoking supplements to the September 1992 and May 1993 Current Population Survey, we investigate whether these workplace policies reduce smoking prevalence and smoking intensity among workers. Our estimates suggest that workplace bans reduce...

Counterbalancing in smoking cue research: a critical analysis.

Cue exposure research has been used to examine key issues in smoking research, such as predicting relapse, testing new medications, investigating the neurobiology of nicotine dependence, and examining reactivity among smokers with comorbid psychopathologies. Determining the order that cues are presented is one of the most critical steps in the design of these investigations. It is widely assumed that cue exposure studies should counterbalance the order in which smoking and control (neutral) cues are presented. This article examines the premises underlying the use of counterbalancing in experimental research, and it evaluates the degree to which counterbalancing is appropriate in smoking cue exposure studies. We reviewed the available literature on the use of counterbalancing techniques in human smoking cue exposure research. Many studies counterbalancing order of cues have not provided critical analyses to determine whether this approach was appropriate. Studies that have reported relevant data, however, suggest that order of cue presentation interacts with type of cue (smoking vs. control), which raises concerns about the utility of counterbalancing. Primarily, this concern arises from potential carryover effects, in which exposure to smoking cues affects subsequent responding to neutral cues. Cue type by order of cue interactions may compromise the utility of counterbalancing. Unfortunately, there is no obvious alternative that is optimal across studies. Strengths and limitations of several alternative designs are considered, and key questions are identified to advance understanding of the optimal conditions for conducting smoking cue exposure studies.

A MEDLINE search was conducted to identify relevant references, to review the information on adverse effects of tobacco smoking and environmental tobacco smoke (ETS). Occupational exposure to ETS causes significant damages to food industry workers. High levels of mutagenic substances have been demonstrated in restaurant air as well as in the urine samples from those workers. Exposition to 3-aminophenyl, a hemoglobin-associated carcinogen. The best way to protect these workers is the reduction of tobacco smoking in restaurants, hotels, bars and taverns. In restaurant workers, ETS attributable risk for lung cancer is evident.

2003-08-01

This study evaluated the possible impact of national smoke-free work-place legislation on employee exposure to environmental tobacco smoke (ETS), employee smoking habits and attitudes on work-place smoking regulations. Repeated cross-sectional questionnaire surveys and indoor air nicotine measurements were carried out before, and 1 and 3 years after the law had come into effect. Industrial, service sector and office work-places from the Helsinki metropolitan area, Finland. A total of 880, 940 and 659 employees (response rates 70%, 75% and 75%) in eight work-places selected from a register kept by the Uusimaa Regional Institute of Occupational Health to represent various sectors of public and private work-places. Reported exposure to ETS, smoking habits, attitudes on smoking at work and measurements of indoor air nicotine concentration. Employee exposure to ETS for at least 1 hour daily decreased steadily during the 4-year follow-up, from 51% in 1994 to 17% in 1995 and 12% in 1998. Respondents' daily smoking prevalence and tobacco consumption diminished 1 year after the enforcement of legislation from 30% to 25%, and remained at 25% in the last survey 3 years later. Long-term reduction in smoking was confined to men. Both smokers' and non-smokers' attitudes shifted gradually towards favouring a total ban on smoking at work. Median indoor airborne nicotine concentrations decreased from 0.9 micro g/m3 in 1994-95 to 0.1 micro g/m3 in 1995-96 and 1998. This is the first follow-up study on a nationally implemented smoke-free work-place law. We found that such legislation is associated with steadily reducing ETS exposure at work, particularly at work-places, where the voluntary smoking regulations have failed to reduce exposure. The implementation of the law also seemed to encourage smokers to accept a non-smoking work-place as the norm.

A Review of Smoking Research In Malaysia.

2016-06-01

Two hundred and seventy one original published materials related to tobacco use were found in a search through a database dedicated to indexing all original data relevant to Medicine and Health in Malaysia from 1996 - 2015. A total of 147 papers were selected and reviewed on the basis of their relevance and implications for future research. Findings were summarised, categorised and presented according to epidemiology, behaviour, clinical features and management of smoking. Most studies are cross-sectional with small sample sizes. Studies on smoking initiation and prevalence showed mixed findings with many small scale studies within the sub-groups. The majority of the studies were related to factors that contribute to initiation in adolescents. Nonetheless, there are limited studies on intervention strategies to curb smoking among this group. There is a lack of clinical studies to analyse tobacco use and major health problems in Malaysia. In addition, studies on the best treatment modalities on the use of pharmacotherapy and behavioural counselling have also remained unexplored. Reasons why smokers do not seek clinic help to quit smoking need further exploration. A finding on the extent of effort carried out by healthcare providers in assisting smokers to make quit attempts is not known. Studies on economic and government initiatives on policies and tobacco use focus mainly on the effects of cigarette bans, increased cigarettes taxes and the influence of the tobacco industry. Recommendations are given for the government to increase efforts in implementing smoke-free legislation, early and tailored interventions. Clinical studies in this area are lacking, as are opportunities to research on ways to reduce smoking initiation age and the most effective quit smoking strategies.

Self-Reported Environmental Tobacco Smoke Exposure and Avoidance Compared with Cotinine Confirmed Tobacco Smoke Exposure among Pregnant Women and Their Infants

Full Text Available Background: Exposure to environmental tobacco smoke (ETS presents substantial health risks for pregnant women and newborn infants. Measurements of ETS include invasive and expensive biochemical tests, as well as less invasive and lower-cost, self-reported exposure and avoidance measures. Better understanding of self-report measures will help to select ETS assessments for evaluation. Methods: This analysis was conducted within the context of a tailored video intervention to reduce tobacco smoking and ETS exposure during pregnancy and after delivery in the control group sample of 147 nonsmoking women. Measurements of salivary cotinine concentration, self-reported ETS exposure, and avoidance behaviors were captured at 32 weeks’ gestation and 6 months postpartum. Results: Salivary cotinine concentration was significantly related to ETS avoidance among pregnant nonsmokers at 32 weeks’ gestation, but not ETS exposure. At 6 months postpartum, both the reported ETS exposure of the infant and maternal avoidance behaviors to reduce her infant’s exposure were associated with the infant’s salivary cotinine concentration. At 32 weeks’ gestation and 6 months postpartum, avoidance behaviors decreased as exposure increased. Discussion: This study suggests that for nonsmoking women during pregnancy, reports of tobacco smoke avoidance are more valid than reports of exposure. After delivery, self-reported ETS exposure or avoidance are associated with each other and the biochemical measurement of salivary cotinine. These results provide researchers and clinicians with evidence to support the inclusion of avoidance behaviors in the selection of ETS measures.

The effects of smoking status and ventilation on environmental tobacco smoke concentrations in public areas of UK pubs and bars

Science.gov (United States)

Carrington, Joanna; Watson, Adrian F. R.; Gee, Ivan L.

UK public houses generally allow smoking to occur and consequently customer ETS exposure can take place. To address this, in 1999 the UK Government and the hospitality industry initiated the Public Places Charter (PPC) to increase non-smoking facilities and provide better ventilation in public houses. A study involving 60 UK pubs, located in Greater Manchester, was conducted to investigate the effects of smoking area status and ventilation on ETS concentrations. ETS markers RSP, UVPM, FPM, SolPM and nicotine were sampled and analysed using established methodologies. ETS marker concentrations were significantly higher ( P mobile in these environments and tends to remain in the smoking areas. This result, together with the much higher reductions in nicotine concentrations between smoking and non-smoking areas compared to other markers, suggests that nicotine is not the most suitable marker to use in these environments as an indicator of the effectiveness of tobacco control policies. The use of ventilation systems (sophisticated HVAC systems and extractor fans in either the on or off mode) did not have a significant effect ( P > 0.05) on ETS marker concentrations in either the smoking or non-smoking areas. The PPC aims to reduce non-smoking customers' exposure through segregation and ventilation and provide customer choice though appropriate signs. This study indicates that although ETS levels are lower in non-smoking sections and signs will assist customers in reducing their exposure, some exposure will still occur because ETS was detected in non-smoking areas. Existing ventilation provision was not effective in reducing exposure and signs advertising ventilated premises may be misleading to customers. Improvements in the design and management of ventilation systems in pubs and bars are required to reduce customer exposure to ETS, if the aims of the PPC are to be met.

Gas-phase organics in environmental tobacco smoke: 2. Exposure-relevant emission factors and indirect exposures from habitual smoking

Science.gov (United States)

Singer, Brett C.; Hodgson, Alfred T.; Nazaroff, William W.

Sorption of emitted gas-phase organic compounds onto material surfaces affects environmental tobacco smoke (ETS) composition and exposures indoors. We have introduced a new metric, the exposure relevant emission factor (EREF) that accounts for sorptive uptake and reemission to give the mass of individual ETS constituents available for exposure over a day in which smoking occurs. This paper describes month-long experiments to investigate sorption effects on EREFs and potential ETS exposures under habitual smoking conditions. Cigarettes were smoked in a 50-m 3 furnished room over a 3-h period 6-7 days per week, with continuous ventilation at 0.3, 0.6, or 2.1 h -1. Organic gas concentrations were measured every few days over 4-h "smoking", 10-h "post-smoking" and 10-h "background" periods. Concentration patterns of volatile ETS components including 1,3-butadiene, benzene and acrolein were similar to those calculated for a theoretical non-sorbing tracer, indicating limited sorption. Concentrations of ETS tracers, e.g. 3-ethenylpyridine (3-EP) and nicotine, and lower volatility toxic air contaminants including phenol, cresols, and naphthalene increased as experiments progressed, indicating mass accumulation on surfaces and higher desorption rates. Daily patterns stabilized after week 2, yielding a steady daily cycle of ETS concentrations associated with habitual smoking. EREFs for sorbing compounds were higher under steady cycle versus single-day smoking conditions by ˜50% for 3-EP, and by 2-3 times for nicotine, phenol, cresols, naphthalene, and methylnaphthalenes. Our results provide relevant information about potential indirect exposures from residual ETS (non-smoker enters room shortly after smoker finishes) and from reemission, and their importance relative to direct exposures (non-smoker present during smoking). Under the conditions examined, indirect exposures accounted for a larger fraction of total potential exposures for sorbing versus non-sorbing compounds

This study demonstrates the ability of tar isolated from environmental tobacco smoke (ETS) to nick DNA in mammalian cells. Solutions of ETS tar behave similarly to aqueous solutions of cigarette tar from mainstream smoke. Both solutions contain the tar semiquinone radical, and this radical associates with the DNA in viable rat alveolar macrophages. Solutions of tar from ETS cause single-strand DNA breaks in rat thymocytes in proportion to the amount of tar present, until a plateau is reached....

Tobacco smoke particles and indoor air quality (ToPIQ - the protocol of a new study

2011-12-01

Full Text Available Abstract Environmental tobacco smoke (ETS is a major contributor to indoor air pollution. Since decades it is well documented that ETS can be harmful to human health and causes premature death and disease. In comparison to the huge research on toxicological substances of ETS, less attention was paid on the concentration of indoor ETS-dependent particulate matter (PM. Especially, investigation that focuses on different tobacco products and their concentration of deeply into the airways depositing PM-fractions (PM10, PM2.5 and PM1 must be stated. The tobacco smoke particles and indoor air quality study (ToPIQS will approach this issue by device supported generation of indoor ETS and simultaneously measurements of PM concentration by laser aerosol spectrometry. Primarily, the ToPIQ study will conduct a field research with focus on PM concentration of different tobacco products and within various microenvironments. It is planned to extend the analysis to basic research on influencing factors of ETS-dependent PM concentration.

A workplace-smoking ban in the Netherlands was introduced on January 1, 2004. Before the ban male and low educated employees were at higher risk for exposure to environmental tobacco smoke (ETS). Effective implementation of the ban should result not only in an overall decline of exposure, but also in the disappearance of systematic differences in exposure between subgroups of employees. Data from a Dutch continuous Internet survey were used. From July 2003 through June 2005, 200 respondents were randomly selected each week. The sample consisted of 11,291 non-smoking, working respondents, aged 16-65 years. ETS exposure decreased among all employees and among subgroups at higher risk before the ban. However, also after the ban, males and low educated employees were still most likely to be exposed to ETS. The workplace-smoking ban was effective in reducing ETS exposure among employees. However, after the ban still 52.2% of non-smoking workers reported to be exposed. We did not find the expected stronger effect among employees who were at higher risk. Both before and after implementation of the ban, males and lower educated employees were about two times more likely to be exposed to ETS.

Environmental tobacco smoke in designated smoking areas in the hospitality industry: exposure measurements, exposure modelling and policy assessment.

McNabola, A; Eyre, G J; Gill, L W

2012-09-01

Tobacco control policy has been enacted in many jurisdictions worldwide banning smoking in the workplace. In the hospitality sector many businesses such as bars, hotels and restaurants have installed designated smoking areas on their premises and allowance for such smoking areas has been made in the tobacco control legislation of many countries. An investigation was carried out into the level of exposure to environmental tobacco smoke (ETS) present in 8 pubs in Ireland which included designated smoking areas complying with two different definitions of a smoking area set out in Irish legislation. In addition, ETS exposure in a pub with a designated smoking area not in compliance with the legislation was also investigated. The results of this investigation showed that the two differing definitions of a smoking area present in pubs produced similar concentrations of benzene within smoking areas (5.1-5.4 μg/m(3)) but differing concentrations within the 'smoke-free' areas (1.42-3.01 μg/m(3)). Smoking areas in breach of legislative definitions were found to produce the highest levels of benzene in the smoking area (49.5 μg/m(3)) and 'smoke-free' area (7.68 μg/m(3)). 3D exposure modelling of hypothetical smoking areas showed that a wide range of ETS exposure concentrations were possible in smoking areas with the same floor area and same smoking rate but differing height to width and length to width ratios. The results of this investigation demonstrate that significant scope for improvement of ETS exposure concentrations in pubs and in smoking areas may exist by refining and improving the legislative definitions of smoking areas in law.

From 26 March 2006, smoking will be prohibited in wholly and substantially enclosed public places in Scotland, and it will be an offence to permit smoking or to smoke in no-smoking premises. We anticipate that implementation of the smoke-free legislation will result in significant health gains associated with reductions in exposure to both environmental tobacco smoke (ETS) and personal tobacco consumption as well as other social and economic impacts. Health Scotland in conjunction with the Information Services Division (ISD) Scotland and the Scottish Executive have developed a comprehensive evaluation strategy to assess the expected short-term, intermediate and long-term outcomes. Using routine health, behavioural and economic data and commissioned research, we will assess the impact of the smoke-free legislation in eight key outcome areas--knowledge and attitudes, ETS exposure, compliance, culture, smoking prevalence and tobacco consumption, tobacco-related morbidity and mortality, economic impacts on the hospitality sector and health inequalities. The findings from this evaluation will make a significant contribution to the international understanding of the health effects of exposure to ETS and the broader social, cultural and economic impacts of smoke-free legislation.

To evaluate whether environmental tobacco smoke (ETS) influences breast cancer incidence, data from a population-based case-control study were analyzed. Respondents with available ETS information assessed by in-person questionnaires included 1356 newly diagnosed cases and 1383 controls. Relative to nonsmokers who reported no residential ETS exposure throughout the life course, the odds ratios (OR) for breast cancer were not substantially elevated in relation to ETS exposure, active smoking, or a joint measure of active and passive smoking (OR, 1.15, 95% CI, 0.90, 1.48). An increased OR, however, was noted among nonsmokers who lived with a smoking spouse for over 27 years (2.10, 95% CI, 1.47, 3.02), although no dose-response was evident. Also, among women with hormone-receptor-positive tumors only, the OR for both active and passive smoking was increased (1.42 for ER + PR + , 95% CI, 1.00, 2.00). Our data suggest that if there is an effect for ETS on breast cancer, that effect is restricted to selected subgroups of women, such as those with long-term exposure from a smoking spouse

Environmental Tobacco Smoke Exposure and Smoke-Free Rules in Homes among Socially-Disadvantaged Populations in Poland

2017-04-01

Full Text Available This study aims to examine the prevalence of exposure to environmental tobacco smoke (ETS in homes among socially-disadvantaged populations in Poland, along with the prevalence and correlates of voluntary implementation of smoke-free home rules. Data concerning 1617 respondents from a cross-sectional study completed in the Piotrkowski District were used, which was part of the “Reducing Social Inequalities in Health” program. Overall, 19.4% of the respondents declared exposure to ETS at home. In the non-smokers group, 15.5%, including 6.6% males and 18.3% females, were exposed to ETS in their place of residence (p < 0.0001. Complete smoke-free rules were adopted by 22.1% of the study participants. Two factors, smoker status and lack of ETS-associated health risk awareness, were found to be significantly associated with no adoption of total smoking bans at home. Socially-disadvantaged non-smokers, especially females from rural areas in Poland, still constitute a large population exposed to ETS in their homes—a challenge from the perspective of public health. Focused efforts are required to address social norms around exposing others to ETS.

Implementation of smoke-free homes in Poland

2016-02-01

Full Text Available Objectives: Exposure to environmental tobacco smoke (ETS constitutes a threat to the health of many people. In order to diminish ETS exposure, countries (including Poland implemented legal restrictions of smoking in public places and worksites. Currently more attention is also paid to reduce overall and residential ETS exposure by voluntary smoke-free home policy adoption. The aim of current analysis was to evaluate the prevalence and determinants of implementing smoking bans at place of residence among economically active males and females in Poland. Material and Methods: Data from cross-sectional, household study – Global Adult Tobacco Survey (GATS 2009–2010 were analyzed. The logistic regression model was applied for appropriate calculations. Results: Out of 3696 studied subjects only 37.1% adopted total smoking ban within the home. Decreased likelihood of adopting total smoking bans was associated with current smoker status, low education attainment, lack of awareness on adverse health consequences of ETS, low level of support for tobacco control policies, and cohabitation with a smoker in both genders. Having smoke-free homes was also linked with age in women, place of residence and work smoking policy in indoor areas in men. Conclusions: Targeted activities to encourage adopting voluntary smoke-free rules among groups least likely to implement 100% smoking bans in the home and activities to decrease social acceptance of smoking in the presence of nonsmokers, children, pregnant woman are urgently needed.

Secondhand smoke (SHS) is the third leading cause of preventable death in the United States and a major source of indoor air pollution, accounting for an estimated 53,000 deaths per year among nonsmokers. Secondhand smoke exposure varies by gender, race/ethnicity, and socioeconomic status. The most effective public health intervention to reduce SHS exposure is to implement and enforce smoke-free workplace policies that protect entire populations including all workers regardless of occupation, race/ethnicity, gender, age, and socioeconomic status. This chapter summarizes community and population-based nursing research to reduce SHS exposure. Most of the nursing research in this area has been policy outcome studies, documenting improvement in indoor air quality, worker's health, public opinion, and reduction in Emergency Department visits for asthma, acute myocardial infarction among women, and adult smoking prevalence. These findings suggest a differential health effect by strength of law. Further, smoke-free laws do not harm business or employee turnover, nor are revenues from charitable gaming affected. Additionally, smoke-free laws may eventually have a positive effect on cessation among adults. There is emerging nursing science exploring the link between SHS exposure to nicotine and tobacco dependence, suggesting one reason that SHS reduction is a quit smoking strategy. Other nursing research studies address community readiness for smoke-free policy, and examine factors that build capacity for smoke-free policy. Emerging trends in the field include tobacco free health care and college campuses. A growing body of nursing research provides an excellent opportunity to conduct and participate in community and population-based research to reduce SHS exposure for both vulnerable populations and society at large.

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.

Social smoking is increasingly prevalent and poses a challenge to traditional cessation practices. Tobacco companies conducted extensive research on social smokers long before health authorities did and marketed products to promote this smoking behavior. Research is described and mechanisms identified that are used to promote social smoking to help improve cessation strategies in this growing group. Searches from 2006 to 2008 of previously secret tobacco industry documents using keywords social smoker, light smoker, casual smoker, youth smoker, and occasional smoker, followed by snowball searching. Data analysis was conducted in 2008. Tobacco industry research identified characteristics of social smokers that include: (1) denial of personal nicotine addiction; (2) self-categorization as a nonsmoker; (3) propensity for decreased tobacco use in response to smoke-free laws; (4) variations in age, education, ethnicity, and socioeconomic backgrounds; and (5) a perceived immunity to personal health effects of tobacco but fear of consequences to others. Tobacco companies developed marketing strategies aimed at social smokers, including "non-habit forming" cigarettes. Previously considered a transient behavior, social smoking is also a stable consumption pattern. Focused clinical questions to detect social smoking are needed and may include, "Have you smoked any cigarettes or used any tobacco products in the past month?" as opposed to "Are you a smoker?" Clinicians should recognize that social smokers might be motivated to quit after education on the dangers of secondhand smoke rather than on personal health risks or with pharmacotherapy.

Exposure to environmental tobacco smoke is a major threat to public health. Greece, having the highest smoking prevalence in the European Union is seriously affected by passive smoking. The purpose of this study was to measure environmental tobacco smoke (ETS) exposure in the non smoking areas of hospitality venues and offices in Greece and to compare the levels of exposure to levels in the US, UK and Ireland before and after the implementation of a smoking ban. Experimental measurements of particulate matter 2.5 microm (PM2.5), performed during a cross sectional study of 49 hospitality venues and offices in Athens and Crete, Greece during February - March 2006. Levels of ETS ranged from 19 microg/m3 to 612 microg/m3, differing according to the place of measurement. The average exposure in hospitality venues was 268 microg/m3 with ETS levels found to be highest in restaurants with a mean value of 298 microg/m3 followed by bars and cafes with 271 microg/m3. ETS levels were 76% lower in venues in which smoking was not observed compared to all other venues (p hospitality venues while levels in Ireland with a total smoking ban are 89% lower and smoke-free communities in the US are 91 - 96% lower than levels in Greece. Designated non-smoking areas of hospitality venues in Greece are significantly more polluted with ETS than outdoor air and similar venues in Europe and the United States. The implementation of a total indoor smoking ban in hospitality venues has been shown to have a positive effect on workers and patrons' health. The necessity of such legislation in Greece is thus warranted.

Abstract Introduction: A major health challenge facing persons who are incarcerated is tobacco smoking. Upon reentry to the community, concerns regarding smoking cessation may be less likely to receive needed attention. Many individuals have partners who are pregnant and/or reside in households where children and pregnant women live. We explored incarcerated adults’ attitudes of smoking in the presence of children and pregnant women and how post-release smoking behaviors are influenced by their attitudes. Methods: Two hundred forty-seven incarcerated adults participated in a smoking cessation randomized clinical trial in a tobacco-free prison. An instrument was developed to examine smoking attitudes and behaviors around children and pregnant women. Moderating effects of smoking factors on post-release abstinence were examined by evaluating interactions between smoking factors and treatment group. Results: Four factors were defined using factor analysis: smoking around children; impact of smoking on child’s health; awareness of environmental tobacco smoke (ETS) risk for pregnant women; and importance of smoking avoidance during pregnancy. We found moderation effects of smoking factors on smoking outcomes which included: treatment group by smoking behavior around children (β = 0.8085; standard error [ SE ] = 0.4002; P = .04); treatment group by impact of smoking on child’s health (β = 1.2390; SE = 0.5632; P = .03) and for those smoking 50% fewer cigarettes post-release, treatment group by smoking impact on child’s health (β = 1.2356; SE = 0.4436; P smoking around children and pregnant women and awareness of ETS risk for pregnant women was not found to be significantly associated with smoking outcomes and requires additional investigation. Among individuals who continue to smoke post-release, effective ETS interventions are needed aimed at protecting children and pregnant women with whom they live. PMID:26014453

To explore families' attitudes about smoking and their perceptions of the effects of environmental tobacco smoke (ETS) exposure on their children. Qualitative study using face-to-face interviews with a semistructured guide in 20 households containing a child under age 5. Content analysis was done on the interview data. Families identified "health protection" as the parental responsibility for children and emphasized helping children make decisions not to smoke. Some reported negative experiences with ETS exposure as children themselves or health problems in their children, reinforcing their opposition to smoke exposure for their children. Most parents said they did not allow smoking in their homes, but some later disclosed that they made exceptions for family and friends. Some parents, however, limited their children's contact with smoking members of their families. Smoking parents expressed guilt about ETS exposure of their children and tried to limit smoking to certain areas of their houses, such as the basement. Other parents, mostly the nonsmokers, did not identify ETS as a problem. Families who maintained smoke-free households identified that family and friends had to "respect" their wishes. To protect children from the negative effects of ETS exposure, nurses should discuss not only if parents smoke but also if family members and friends are allowed to smoke in the home. It would be helpful to assess the priority that parents set on ETS and how they attempt to prevent it in their daily lives.

This study aims to examine the prevalence of exposure to environmental tobacco smoke (ETS) in homes among socially-disadvantaged populations in Poland, along with the prevalence and correlates of voluntary implementation of smoke-free home rules. Data concerning 1617 respondents from a cross-sectional study completed in the Piotrkowski District were used, which was part of the "Reducing Social Inequalities in Health" program. Overall, 19.4% of the respondents declared exposure to ETS at home. In the non-smokers group, 15.5%, including 6.6% males and 18.3% females, were exposed to ETS in their place of residence ( p smoker status and lack of ETS-associated health risk awareness, were found to be significantly associated with no adoption of total smoking bans at home. Socially-disadvantaged non-smokers, especially females from rural areas in Poland, still constitute a large population exposed to ETS in their homes-a challenge from the perspective of public health. Focused efforts are required to address social norms around exposing others to ETS.

The ultimate goal of the research reported in this series of three articles is to derive distributions of doses of selected environmental tobacco smoke (ETS)-related chemicals for nonsmoking workers. This analysis uses data from the 16-City Study collected with personal monitors over the course of one workday in workplaces where smoking occurred. In this article, the authors describe distributions of ETS chemical concentrations and the characteristics of those distributions for the workplace exposure. Next, they present population parameters relevant for estimating dose distributions and the methods used for estimating those dose distributions. Finally, they derive distributions of doses of selected ETS-related constituents obtained in the workplace for people in smoking work environments. Estimating dose distributions provided information beyond the usual point estimate of dose and showed that the preponderance of individuals exposed to ETS in the workplace were exposed at the low end of the dose distribution curve. The results of this analysis include estimations of hourly maxima and time-weighted average (TWA) doses of nicotine from workplace exposures to ETS and doses derived from modeled lung burdens of ultraviolet-absorbing particulate matter (UVPM) and solanesol resulting from workplace exposures to ETS (extrapolated from 1 day to 1 year).

Full Text Available Abstract Background Exposure to environmental tobacco smoke is a major threat to public health. Greece, having the highest smoking prevalence in the European Union is seriously affected by passive smoking. The purpose of this study was to measure environmental tobacco smoke (ETS exposure in the non smoking areas of hospitality venues and offices in Greece and to compare the levels of exposure to levels in the US, UK and Ireland before and after the implementation of a smoking ban. Methods Experimental measurements of particulate matter 2.5 μm (PM2.5, performed during a cross sectional study of 49 hospitality venues and offices in Athens and Crete, Greece during February – March 2006. Results Levels of ETS ranged from 19 μg/m3 to 612 μg/m3, differing according to the place of measurement. The average exposure in hospitality venues was 268 μg/m3 with ETS levels found to be highest in restaurants with a mean value of 298 μg/m3 followed by bars and cafes with 271 μg/m3. ETS levels were 76% lower in venues in which smoking was not observed compared to all other venues (p Conclusion Designated non-smoking areas of hospitality venues in Greece are significantly more polluted with ETS than outdoor air and similar venues in Europe and the United States. The implementation of a total indoor smoking ban in hospitality venues has been shown to have a positive effect on workers and patrons' health. The necessity of such legislation in Greece is thus warranted.

Recently, accompanying the increase of the use of fossil fuel, the environment destruction due to the sulfur oxides and nitrogen oxides contained in combustion smoke has become a serious problem. The development of flue gas smoke treatment technology by using electron beam was started in Japan, and attention has been paid worldwide as the promising dry type simultaneous desulfurizing and denitrating process. In this process, by adding ammonia to smoke, and irradiating electron beam on it, ammonium nitrate and ammonium sulfate are formed. As to the reaction mechanism of denitration and desulfurization, radical formation, radical reaction, denitration mechanism, desulfurization mechanism, the particle size distribution of the formed aerosol, the amounts of denitration and desulfurization by electron beam smoke treatment process, the improvement of the denitration efficiency by multi-stage irradiation method and the improvement of the desulfurization rate by low temperature irradiation, and the basic test toward the pilot test are explained. The basic research for putting this system to practical use was carried out jointly by Japan Atomic Energy Research Institute, Chubu Electric Power Co., Inc., and Ebara Seisakusho for standard coal burning smoke in Japan. The verifying test at the pilot plant in Shinnagoya Thermal Power Station was carried out, and it was verified that this process can be used practically for treating coal-burning smoke. (K.I.)

Full Text Available Studies suggest childhood exposure to environmental tobacco smoke (ETS leads to increased incidence of infections of the lower respiratory tract. The objective of this study was to determine whether perinatal exposure to ETS increases the incidence, morbidity and severity of respiratory influenza infection and whether a secondary bacterial challenge at the peak of a pre-existing viral infection creates an enhanced host-pathogen susceptibility to an opportunistic infection. Timed-pregnant female Balb/c mice were exposed to either ETS for 6 h/day, 7 d/week beginning on gestation day 14 and continuing with the neonates to 6 weeks of age. Control animals were exposed to filtered air (FA. At the end of exposure, mice were intranasally inoculated with a murine-adapted influenza A. One week later, an intranasal inoculation of S. aureus bacteria was administered. The respective treatment groups were: bacteria only, virus only or virus+bacteria for both FA and ETS-exposed animals for a total of six treatment groups. Animal behavior and body weights were documented daily following infection. Mice were necropsied 1-day post-bacterial infection. Bronchoalveolar lavage fluid (BALF cell analysis demonstrated perinatal exposure to ETS, compared to FA, leads to delayed but enhanced clinical symptoms and enhanced total cell influx into the lungs associated with viral infection followed by bacterial challenge. Viral infection significantly increases the number of neutrophils entering the lungs following bacterial challenge with either FA or ETS exposure, while the influx of lymphocytes and monocytes is significantly enhanced only by perinatal ETS exposure. There is a significant increase in peribronchiolar inflammation following viral infection in pups exposed to ETS compared with pups exposed to FA, but no change is noted in the degree of lung injury between FA and ETS-exposed animals following bacterial challenge. The data suggests perinatal exposure to ETS

Fine particulate matter samples were collected in an urban ambient fixed site and, outside and inside residencies in Athens greater area, Greece. n-Alkanes, iso/anteiso-alkanes and polycyclic aromatic hydrocarbons (PAHs) were identified by gas chromatography and mass spectrometry. The values of concentration diagnostic ratios indicated a mixture of vehicular emissions, fuel evaporation, oil residues and environmental tobacco smoke (ETS) in outdoor and indoor samples. Particulate iso/anteiso-alkanes, specific tracers of ETS, were detected in both non-smoking and smoking households. The indoor-to-outdoor ratios of particulate iso/anteiso-alkanes and unresolved complex mixture (a tracer of outdoor air pollution) in non-smoking households were comparable to the measured air exchange rate. This suggested that penetration of outdoor air was solely responsible for the detection of tobacco smoke particulate tracers in indoor non-smoking environments. Overall, residential outdoor concentrations accounted for a large fraction (from 25 up to 79%) of indoor aliphatic and polyaromatic hydrocarbons. Open windows/doors and the operation of an air condition unit yielded also in higher indoor concentrations than those measured outdoors.

Environmental tobacco smoke (ETS) exposure induces serious negative health consequences, of which the increased risk of cardiovascular diseases, cancer, respiratory symptoms and poor pregnancy outcomes appear to be most important. Taking into account those health consequences of ETS exposure most countries have introduced legislation to ban or restrict smoking in public places. In this paper the effectiveness of the introduced legislation was analyzed with regard to the protection of hospitality workers from ETS exposure in the workplace. The analysis of 12 papers published after 2000 covered the year of publication, type of legislation, study population, hospitality venue (pub, bar, restaurant, disco) and type of markers or self-reported perception of exposure to ETS. The analysis indicates that the legislation to ban smoking in hospitality venues protects workers from ETS exposure when the venues are 100% tobacco smoke free. The reduction of the cotinine level in biological samples after the implementation of smoke free law was 57-89%, comparing to the biomarker level in the samples taken before the new law was introduced. About 90% of reduction in nicotine and PM levels was also noted. In addition, the positive self perception reported by workers proved the effectiveness of new legislation protecting them from ETS exposure.

Secret science: tobacco industry research on smoking behaviour and cigarette toxicity.

A lack of scientific data remains the principal obstacle to regulating cigarette toxicity. In particular, there is an immediate need to improve our understanding of the interaction between smoking behaviour and product design, and its influence on cigarette deliveries. This article reviews internal tobacco industry documents on smoking behaviour research undertaken by Imperial Tobacco Limited (ITL) and British-American Tobacco (BAT). BAT documents indicate that smokers vary their puffing behaviour to regulate nicotine levels and compensate for low-yield cigarettes by smoking them more intensely. BAT research also shows that the tar and nicotine delivered to smokers is substantially greater than the machine-smoked yields reported to consumers and regulators. Internal documents describe a strategy to maximise this discrepancy through product design. In particular, BAT developed elastic cigarettes that produced low yields under standard testing protocols, whereas in consumers' hands they elicited more intensive smoking and provided higher concentrations of tar and nicotine to smokers. Documents also show that BAT pursued this product strategy despite the health risks to consumers and ethical concerns raised by senior scientists, and paired it with an equally successful marketing campaign that promoted these cigarettes as low-tar alternatives for health-concerned smokers. Overall, the documents seem to reveal a product strategy intended to exploit the limitations of the testing protocols and to intentionally conceal from consumers and regulators the potential toxicity of BAT products revealed by BAT's own research. Tobacco industry research underscores the serious limitations of the current cigarette testing protocols and the documents describe deceptive business practices that remain in place.

This study quantified casino dealers' occupational exposure to environmental tobacco smoke (ETS). We measured casino dealers' exposure to ETS components by analyzing full-shift air and preshift and postshift urine samples. Casino dealers were exposed to nicotine, 4-vinyl pyridine, benzene, toluene, naphthalene, formaldehyde, acetaldehyde, solanesol, and respirable suspended particulates. Levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) in urine increased significantly during an 8-hour work shift both with and without adjustment for creatinine clearance. Creatinine-unadjusted cotinine significantly increased during the 8-hour shift, but creatinine-adjusted cotinine did not increase significantly. Casino dealers at the three casinos were exposed to airborne ETS components and absorbed an ETS-specific component into their bodies, as demonstrated by detectable levels of urinary NNAL. The casinos should ban smoking on their premises and offer employee smoking cessation programs.

Full Text Available Abstract Background Detrimental effects of environmental tobacco smoke (ETS exposure on child health are well documented. Because young children's primary exposure to ETS occurs in homes and automobiles, voluntary smoking restrictions can substantially reduce exposure. We assessed the prevalence of home and automobile smoking bans among U.S.- and Mexico-born Hispanics in the southwestern United States, and examined the influence of mother's country of birth and smoking practices on voluntary smoking bans and on child ETS exposure. Methods U.S.- and Mexico-born Hispanic mothers of children aged 2 through 12 years were systematically sampled from health clinics in Albuquerque, New Mexico. In-person interviews were conducted with 269 mothers (75.4% response rate to obtain information on main study outcomes (complete versus no/partial home and automobile smoking bans; child room and automobile ETS exposure and risk factors (mother's country of birth, maternal and household smoking behaviors. Data were analyzed with chi square tests and logistic regression models. Results Three-fourths (74–77% of U.S.-born and 90–95% of Mexico-born mothers reported complete automobile and home smoking bans. In multivariate analyses, mother's U.S nativity, mother's current smoking, and presence of other adult smokers in the home were associated with significantly increased odds of not having a complete home or automobile smoking ban. Mother's smoking was associated with child ETS exposure both indoors (odds ratio [OR] = 3.31 and in automobiles (OR = 2.97. Children of U.S.-born mothers had increased odds of exposure to ETS indoors (OR = 3.24; 95% confidence interval [CI]: 1.37–7.69, but not in automobiles. Having complete smoking bans was associated with substantially reduced odds of child ETS exposure both indoors (OR = 0.10; 95% CI: 0.04–0.27 and in automobiles (OR = 0.14; 95% CI: 0.05–0.36.

We estimated the mortality from various diseases caused by cigarette smoking using two methods and compared the results. In one method, the "Prevent" model is used to simulate the effect on mortality of the prevalence of cigarette smoking derived retrospectively. The other method, suggested by R....... Peto et al (Lancet 1992;339:1268-1278), requires data on mortality from lung cancer among people who have never smoked and among smokers, but it does not require data on the prevalence of smoking. In the Prevent model, 33% of deaths among men and 23% of those among women in 1993 from lung cancer...... are small and appear to be explicable. The Prevent model can be used for more general scenarios of effective health promotion, but it requires more data than the Peto et al method, which can be used only to estimate mortality related to smoking....

The aim of the study was to analyze the nurse attitudes towards smoke-free regulations in public places. The study population consisted of 299 nurses. Among the study population questionnaire was conducted including socio-demographic characteristic, smoking and ETS profile, knowledge about health effects of smoking and abilities for conduction of antismoking counseling. Detail information was collected about nurse opinion on smoke-free public places such as offices, other workplaces, health and educational buildings, restaurants and bars. About 18% of study participants declared current tobacco smoking and 25% were former smokers. Almost all participating in the study women (85%-98%) are in favor of smoking ban in offices, health and educational buildings. 75% supported smoking ban in workplaces but 15% of them were somewhat opposed. Most of the nurses were in favor of smoke-free restaurants (64%) but they were less likely to support smoke-free bars, pubs and clubs (45%). Unfortunately 63% of interview women do not accept smoking ban in private cars. The percentage of women who support total ban of smoking in the presence of pregnant women was 93% and in the presence of children 79%. It is important to conduct educational and informational activities to increase public awareness on health consequences of active and passive smoking and the ways of elimination of such exposures.

Tobacco smoking – popularity and main trends on research

Full Text Available Each year smoking leads to the premature death of over 5 million people around the world. However, the tobacco industry took actions like introducing cigarettes which contain less nicotine and tar aimed at not only maintaining the old clientele, but also attracting a new one. The knowledge of the adverse health effects of smoking became widespread in the second half of the 20th century and changed attitudes towards smoking. In recent years, in many markets in the world a new device representing an alternative to tobacco products was introduced. Electronic cigarettes are designed to deliver nicotine into the respiratory system in the form of an aerosol. They have been gaining more and more popularity, as evidenced by the increase in the percentage of users as well as in the numbers of publications about them. Currently, opinions are divided and the e-cigarette has almost as many supporters as opponents. All this resembles the situation concerning conventional cigarettes in the 20th century. The aim of the study is to gather the most significant information concerning, on the one hand, the spreading popularity of tobacco smoking and, on the other, the research topics undertaken by contemporary scientists, as well as the government actions meant to protect from dangers of nicotine addiction in the 20th and 21st century. New developments of products containing this highly addictive substance call for systematic research in the interest of public health.

Wildfire smoke exposure and human health: Significant gaps in research for a growing public health issue.

Understanding the effect of wildfire smoke exposure on human health represents a unique interdisciplinary challenge to the scientific community. Population health studies indicate that wildfire smoke is a risk to human health and increases the healthcare burden of smoke-impacted areas. However, wildfire smoke composition is complex and dynamic, making characterization and modeling difficult. Furthermore, current efforts to study the effect of wildfire smoke are limited by availability of air quality measures and inconsistent air quality reporting among researchers. To help address these issues, we conducted a substantive review of wildfire smoke effects on population health, wildfire smoke exposure in occupational health, and experimental wood smoke exposure. Our goal was to evaluate the current literature on wildfire smoke and highlight important gaps in research. In particular we emphasize long-term health effects of wildfire smoke, recovery following wildfire smoke exposure, and health consequences of exposure in children. Copyright © 2017 Elsevier B.V.

To investigate the influence of maternal smoke exposure on neonatal and maternal antioxidant status, 39 mothers who were active smokers, 14 mothers exposed to environmental tobacco smoke (ETS), 17 controls, and their newborns were included in a prospective, controlled study. Plasma total antioxidant capacity, measured as total radical-trapping antioxidant parameter (TRAP) and ferric reducing antioxidant power (FRAP), and concentrations of specific antioxidants were measured in cord and in maternal blood. A similar, significant increase in ceruloplasmin concentration was observed in neonates born to actively smoking mothers and in those born to ETS exposed mothers. Uric acid and TRAP concentrations were significantly increased in ETS-exposed newborns and their mothers, compared to newborns and mothers from the active smoking and no-exposure groups with a trend towards increased uric acid, TRAP and FRAP concentrations being observed in the active smokers group. Neonatal and maternal antioxidant concentrations correlated significantly, except for ceruloplasmin. Cord blood vitamin A, E and C concentrations were unaffected by smoke exposure. These results show that maternal active smoking as well as ETS exposure significantly affect neonatal and maternal antioxidant status. Copyright (c) 2005 S. Karger AG, Basel

Having a yarn about smoking: using action research to develop a 'no smoking' policy within an Aboriginal Health Organisation.

2011-11-01

This article reports on a culturally appropriate process of development of a smoke-free workplace policy within the peak Aboriginal Controlled Community Health Organisation in Victoria, Australia. Smoking is acknowledged as being responsible for at least 20% of all deaths in Aboriginal communities in Australia, and many Aboriginal health workers smoke. The smoke-free workplace policy was developed using the iterative, discursive and experience-based methodology of Participatory Action Research, combined with the culturally embedded concept of 'having a yarn'. Staff members initially identified smoking as a topic to be avoided within workplace discussions. This was due, in part, to grief (everyone had suffered a smoking-related bereavement). Further, there was anxiety that discussing smoking would result in culturally difficult conflict. The use of yarning opened up a safe space for discussion and debate, enabling development of a policy that was accepted across the organisation. Within Aboriginal organisations, it is not sufficient to focus on the outcomes of policy development. Rather, due attention must be paid to the process employed in development of policy, particularly when that policy is directly related to an emotionally and communally weighted topic such as smoking.

Full Text Available Traditionally, nicotine from second hand smoke (SHS, active or passive, has been considered the most prevalent substance of abuse used during pregnancy in industrialized countries. Exposure to environmental tobacco smoke (ETS is associated with a variety of health effects, including lung cancer and cardiovascular diseases. Tobacco is also a major burden to people who do not smoke. As developing individuals, newborns and children are particularly vulnerable to the negative effects of SHS. In particular, prenatal ETS has adverse consequences during the entire childhood causing an increased risk of abortion, low birth weight, prematurity and/or nicotine withdrawal syndrome. Over the last years, a decreasing trend in smoking habits during pregnancy has occurred, along with the implementation of laws requiring smoke free public and working places. The decrease in the incidence of prenatal tobacco exposure has usually been assessed using maternal questionnaires. In order to diminish bias in self-reporting, objective biomarkers have been developed to evaluate this exposure. The measurement of nicotine and its main metabolite, cotinine, in non-conventional matrices such as cord blood, breast milk, hair or meconium can be used as a non-invasive measurement of prenatal SMS in newborns. The aim of this review is to highlight the prevalence of ETS (prenatal and postnatal using biomarkers in non-conventional matrices before and after the implementation of smoke free policies and health effects related to this exposure during foetal and/or postnatal life.

A pilot study of the behavior of gas- and particle-phase ETS tracers in residences

Apte, Michael; Gundel, Lara; Dod, Raymond; Chang, Gee-Min; Sextro, Richard

2002-01-01

Our previous study of environmental tobacco smoke (ETS) in a three-room environmental chamber showed that smoking history significantly influenced inter-room ETS transport, particularly of gas-phase nicotine. We conducted a three-home pilot study where smoking was limited to one room. Single-smoker residences were monitored during five one-week periods while the smoker participated in a smoking cessation program. Nicotine traced ETS particles were detected reliably in the smoking rooms (SRs) and unreliably in the non-smoking rooms (NSRs). On average, the ventilation- and volume-normalized smoking rate, 0.1 Cigarette-h(sup -1) m(sup -3), added about 17 and 4(micro)g m(sup -3) of ETS particles into the SR and NSR, while average nicotine concentration increases were 2 and 0.06(micro)g m(sup -3), respectively. Thus, nicotine tracers may underestimate ETS particle exposure in a NSR (e.g., a child's bedroom) by a factor of 2 to 8. In other words, ETS exposure predicted from nicotine concentrations could be almost an order of magnitude lower than actual exposure

Although active tobacco smoking has been considered a major risk factor for head and neck cancer, few studies have evaluated environmental tobacco smoke (ETS) and its interaction with mutagen sensitivity on the risk of head and neck cancer. We investigated the relationship between ETS and head and neck cancer in a case-control study of 173 previously untreated cases with pathologically confirmed diagnoses of squamous cell carcinoma of the head and neck and 176 cancer-free controls at Memorial Sloan-Kettering Cancer Center between 1992 and 1994. A structured questionnaire was used to collect ETS exposure and other covariates including a history of active tobacco smoking and alcohol use. ETS measures include a history of ETS exposure at home and at workplace. The associations between passive smoking and head and neck cancer were analyzed by Mantel-Haenszel methods and logistic regression models. Additive and multiplicative models were used to evaluate effect modifications between ETS and mutagen sensitivity. The crude odds ratio (OR) for ETS exposure was 2.8 [95% confidence intervals (CI), 1.3-6.0]. Controlling for age, sex, race, education, alcohol consumption, pack-years of cigarette smoking, and marijuana use, the risk of squamous cell carcinoma of the head and neck was increased with ETS (adjusted OR, 2.4; 95% CI, 0.9-6.8). Dose-response relationships were observed for the degree of ETS exposure; the adjusted ORs were 2.1 (95% CI, 0.7-6.1) for those with moderate exposure and 3.6 (95% CI, 1.1-11.5) for individuals with heavy exposure (P for trend = 0.025), in comparison with those who never had ETS exposures. These associations and the dose-response relationships were still present when the analysis was restricted to nonactive smoking cases and controls (crude OR, 2.2; 95% CI, 0.6-8.4). Crude odds ratios were 1.8 for those with moderate ETS exposure and 4.3 for individuals with heavy ETS exposure among nonsmoking cases and controls (P for trend = 0.008). More

Objective: To determine quantitatively the extent of exposure of hospitality workers to environmental tobacco smoke (ETS) exposure during the course of a work shift, and to relate these results to the customer smoking policy of the workplace. Subjects: Three categories of non-smoking workers were recruited: (1) staff from hospitality premises (bars and restaurants) that permitted smoking by customers; (2) staff from smokefree hospitality premises; and (3) government employees in smokefree workplaces. All participants met with a member of the study team before they began work, and again at the end of their shift or work day. At each meeting, participants answered questions from a standardised questionnaire and supplied a saliva sample. Main outcome measures: Saliva samples were analysed for cotinine. The difference between the first and second saliva sample cotinine concentrations indicated the degree of exposure to ETS over the course of the work shift. Results: Hospitality workers in premises allowing smoking by customers had significantly greater increases in cotinine than workers in smokefree premises. Workers in hospitality premises with no restrictions on customer smoking were more highly exposed to ETS than workers in premises permitting smoking only in designated areas. Conclusions: Overall, there was a clear association between within-shift cotinine concentration change and smoking policy. Workers in premises permitting customer smoking reported a higher prevalence of respiratory and irritation symptoms than workers in smokefree workplaces. Concentrations of salivary cotinine found in exposed workers in this study have been associated with substantial involuntary risks for cancer and heart disease. PMID:12035005

Tobacco smoking is a serious and preventable health hazard that can cause or exacerbate a number of diseases and shorten life expectancy, but the role of smoking as an etiologic factor in the development of skin disease is largely unknown. Although epidemiological evidence is sparse, findings...... suggest that tobacco smoking is a contributing factor in systemic lupus erythematosus, psoriasis, palmoplantar pustulosis, cutaneous squamous cell carcinoma, hidradenitis suppurativa, and genital warts. In contrast, smoking may confer some protective effects and mitigate other skin diseases, notably...... pemphigus vulgaris, pyoderma gangrenosum, aphthous ulcers, and Behçet's disease. Various degenerative dermatologic conditions are also impacted by smoking, such as skin wrinkling and dysregulated wound healing, which can result in post-surgical complications and delayed or even arrested healing of chronic...

to assess knowledge, attitudes and behaviours about environmental tobacco smoke (ETS) in cars and homes in Queensland. 1,026 randomly selected Queensland residents (84% response) participated in a computer assisted telephone survey to assess knowledge, attitudes and behaviours about ETS in cars and homes; and attitudes towards restrictions on smoking in a range of contexts. Most respondents are aware of the negative health effects of ETS and have smoking bans in their cars (75.8%) and homes (76.8%), however bans are less prevalent for smokers (cars: 37.9%; homes: 51%; p=0.000). For cars/homes, most smokers who did not have smoking bans would not smoke at all around pregnant women (67.7%/53.7%); fewer would refrain for childrennon-smoking adults (31.3%/17.9%); and children 13-17 years (30.9%/21.2%). Parent smokers are less likely to not smoke at all around children>or=2 years (p=0.000) compared to non-parent smokers. Most respondents support car/ home smoking bans for childrenETS in cars and homes, however this varies by context, smoking and parental status.

By means of special devices there was performed research of air in premises of 17 cafes and restaurants where nargile is smoking. In the premises during the day and more there was evaluated a concentration of the following markers of tobacco smoke: carbon monoxide (CO), nicotine, tobacco smoke particles PM2,5 andpolycyclic aromatic hydrocarbons (PAHs). In the air of the examined enterprises the concentration of the major markers of tobacco smoke was established to exceed by several times acceptable and safe levels. At that in cafes and restaurants where nargile smoking the higher concentration of CO and PAHs was on average significantly more frequently than in a cafes with a rare nargile smoking. The data obtained can be used to refute the opinion on the safety of nargile smoking and tobacco smoke from the nargiles. All modern legislative and administrative measures to restrict and ban tobacco smoking should be extend to smoking nargile.

Environmental tobacco smoke and childhood asthma

Directory of Open Access Journals (Sweden)

Dae Jin Song

2010-02-01

Full Text Available In recent years, environmental tobacco smoke (ETS has become an important worldwide public health issue. Children are particularly vulnerable to ETS because they are still developing. ETS exposure causes a wide range of adverse health effects on childhood asthma. There is convincing evidence that ETS exposure is causally associated with an increased prevalence of asthma, increased severity of asthma and worsening asthma control in children who already have the disease, even though a causal relationship with asthma onset is not yet established for asthma incidence. Mechanisms underlying these adverse effects of ETS are not clearly elucidated but e studies on this issue suggest that genetic susceptibility, impaired lung function, and augmented airway inflammation and remodeling may be involved. Children with asthma are just as likely to be exposed to ETS as children in general and there is no risk-free level of exposure. Therefore, providing a smoke-free environment may be of particular importance to the asthmatic children exposed to ETS who have adverse asthma outcomes, as well as to children with genetic susceptibility who are at increased risk of developing asthma upon exposure to ETS in early childhood.

Advertising is not only a communication tool, but also a differentiation marketing strategy in tobacco industry (Hong et al., 1987). Smoking advertising is a significant stimulation of cigarette demands. It has to take the blame for the increasing smoking-related deaths (Pierce et al., 1999). As a result, it has been banned in the United States in the 1960s and China in 2005 (Pierce et al., 1998). According to the literature and the database of the smoking advertising, from year 1901 to 2000,...

Full Text Available This study examines the prevalence and tobacco use patterns among adult social assistance beneficiaries and their interest in quitting. The results are based on data collected in a cross-sectional survey conducted among adults in the Piotrkowski district. A sample of 3636 social assistance beneficiaries produced a total of 1817 respondents who completed face-to-face questionnaires. Overall, 37.1% of the respondents, including 52.8% men and 29.6% women, were current smokers. Over one third of the smokers reported their willingness to quit. In the study population, several characteristics were significantly associated with the current daily smoking: male gender, low educational attainment, unemployment or temporary employment, lack of awareness of smoking-associated health risks, use of e-cigarettes, and exposure to environmental tobacco smoke (ETS. The intention to quit smoking among the daily smokers was positively correlated with their awareness of smoking-associated health risks, lack of previous quit attempts, and low exposure to ETS. Smoking prevalence among social assistance recipients tends to be higher than in the general population, but more than half of the smokers are willing to quit. There is an urgency to develop policies tailored to the needs of these disadvantaged population groups.

Effects of environmental tobacco smoke on the respiratory health of children

Cinar, N.D.; Dede, C.

2010-01-01

Infections of the respiratory tract are the most common acute illness of childhood. Apart from the morbidity (and occasional mortality) attributable to respiratory infections, they also represent risk factors for asthma and possibly other chronic respiratory effects in later life. Children's exposure to harmful substances of tobacco smoke begins at prenatal period, if pregnant woman smokes after the delivery, it continues postnatally to be paced. Children are especially sensitive to the respiratory effects of environmental tobacco smoke (ETS) exposure. ETS exposure is an significant and avoidable risk factor for respiratory diseases among children. ETS is a wide-spread environmental pollutant that has been long linked with respiratory problems. In children of all ages ETS exposure has been found to be associated with increased respiratory symptoms such as wheeze and cough. The role ETS plays in the development of atopy is of great interest, as atopy is closely related to the development of childhood asthma. Exposure to environmental tobacco smoke is preventable. This review discusses primarily on impact of ETS on during the fetal period and infancy and childhood.This paper reviews of several articles between year 1992- 2009 obtained from the internet; Pubmed and Medline.

A study has been conducted to investigate the distribution of aliphatic and polycyclic aromatic hydrocarbons in Environmental Tobacco Smoke (ETS). ETS is the smoke that is present in the ambient air due to smoking of tobacco. Types of cigarettes (C1R1 and C6R1) were chosen based on a result of a simple survey carried out to determine the consumer choice of cigarette brand. In analyzing the ETS, volunteers were asked to smoke each brand of cigarette in a closed room and the ETS was then collected using the high Volume Air Sampler fitted with a glass fiber filter. Smoke samples from the glass fiber filter were then extracted using Ultrasonic Agitation and fractionated into aliphatic and aromatic fraction using silica-alumina column. Identification and quantification was done using gas chromatography with flame ionization detector. Results indicated the presence of n-alkanes in ETS, ranging from C 13 to C 36 with an odd to even carbon number predominance with Carbon Preference Index(CPI) values ranging from 3.34 to 4.90. Total identified resolved aliphatic hydrocarbons (TIRAH) concentration found in ETS ranged from 590 μg m -3 to 591 μg m -3 with the percentage of plant wax n-alkanes ranging from 61% to 64% of the TIRAH found in ETS samples. In source apportionment, CPI > 1 and high percentage of plant wax n-alkanes has generally been associated with the contribution of terrestrial plant source, thus this result indicates that even after curing process and smoking of tobacco, the overall signature of the source of n-alkanes is still preserved. Amount of PAHs detected in all ETS samples ranged from 11.7 ng m -3 to 56.1 ng m -3 . Results also indicated the presence of medium to high molecular weight PAHs with dominant presence of benzo(g, h, i)perylene compound. This result seems to support the contention that smoking process involves a high temperature burning with an oxygen deficient zone in the cigarette itself. Although the concentrations were low, the

The effects of the enforcement of a smoke-free workplace policy on health-related quality of life (HRQOL) among a healthy population are poorly understood. The present study was undertaken to examine the effects of the enforcement of a smoke-free school policy on HRQOL among healthy non-smoking schoolteachers with respect to their exposure to passive smoke. Two self-reported questionnaire surveys were conducted, the first before and the second after the enforcement of a total smoke-free public school policy in Nara City. A total of 1534 teachers were invited from 62 schools, and their HRQOL was assessed using six domains extracted from the Medical Outcomes Survey Short Form-8 questionnaire (SF-8): general health perception (GH), role functioning-physical (RP), vitality (VT), social functioning (SF), mental health (MH), and role functioning-emotional (RE). The participants were divided into two groups according to their exposure to environmental tobacco smoke (ETS) at baseline: participants not exposed to ETS at school (non-smokers), and participants exposed to ETS at school (passive smokers). Changes in each SF-8 score were evaluated using paired t-tests for each group, and their inter-group differences were evaluated using multiple linear regression analyses adjusted for sex, age, school type, managerial position, and attitude towards a smoke-free policy. After ineligible subjects were excluded, 689 teachers were included in the analyses. The number of non-smokers and passive smokers was 447 and 242, respectively. Significant changes in SF-8 scores were observed for MH (0.9; 95% confidence interval [CI], 0.2-1.5) and RE (0.7; 95% CI, 0.0-1.3) in non-smokers, and GH (2.2; 95% CI, 1.2-3.1), VT (1.8; 95% CI, 0.9-2.7), SF (2.7; 95% CI, 1.6-3.8), MH (2.0; 95% CI, 1.0-2.9), and RE (2.0; 95% CI, 1.2-2.8) in passive smokers. In the multiple linear regression analyses, the net changes in the category scores of GH (1.8; 95% CI, 0.7-2.9), VT (1.4, 95% CI, 0.3-2.5), SF (2

Smoking restrictions on campus: changes and challenges at three Canadian universities, 1970-2010.

2013-01-01

This article examines the restriction of smoking on university campuses in the Canadian context. Indoor smoking on campus is now completely prohibited by law, and universities are increasingly moving to restrict, or prohibit, outdoor smoking on their grounds. The research focuses on three case studies to identify changes in spatial restrictions on campus smoking over the last four decades (1970-2010), and to determine the challenges involved in establishing bans in outdoor areas of campus. The three universities were selected for their different approaches to the issue of outdoor smoking. Data collection involved semi-structured interviews with 36 key informants, conducted from September 2010 to January 2011, supplemented by documentary information. Interview data were analysed thematically. Protection against environmental tobacco smoke (ETS) on campus proceeded incrementally, via policy-making at the provincial, municipal and institutional levels. Historically, institutional bans on indoor smoking were particularly significant, but their health benefits could be limited by the presence of private property on campus. Universities continue to initiate smoking restrictions today, with respect to outdoor bans. However, respondents reported myriad challenges in developing, implementing and maintaining such bans. Five principal concerns were articulated: the need for ongoing policy communication; management of community relations as smokers are displaced from campus; enforcement to ensure that the policy has practical effect; safety concerns; and difficulties relating to campus layout. Because challenges are diverse and contextual, effective protection against outdoor ETS on campus is likely to require an ongoing commitment on the part of administrators. © 2012 Blackwell Publishing Ltd.

Full Text Available Objetive: To evaluate the exposure to environmental tobacco smoke (ETS of the childhood population in this community and its relationship with asthma symptoms. Methods: A cross-sectional study was conducted using the International Study of Asthma and Allergies in Childhood (ISAAC questionnaire on children and adolescents in this community. The symptoms “wheezing ever”, “current asthma”, “severe asthma”, and “exercise-induced asthma” were defined by this questionnaire. Parental smoking was classified into four mutually exclusive categories: 1 no parent smokes; 2 only the mother smokes; 3 only the father smokes; and 4 both parents smoke. The odds ratio of the prevalence of asthma symptoms according to ETS exposure was calculated using logistic regression. Results: A total of 10,314 children and 10,453 adolescents were included. Over 51% of the children and adolescents were exposed to ETS at home. ETS is associated with a higher prevalence of asthma symptoms, particularly if the mother or both parents smoke. Conclusion: The prevalence of ETS is still high in this community, although there has been a decreasing tendency in the last 15 years. ETS is associated with higher prevalence of asthma.

After the invention of the cigarette 1881 the health consequences of active smoking were fully known only in 1964. Since 1986 research findings allow increasingly stronger conclusions about the impact of passive smoking on health, especially for lung cancer, cardiovascular and respiratory disease in adults and children and the sudden infant death syndrome. On the basis of current consumption patterns, approximately 450 million adults will be killed by smoking between 2000 and 2050. At least half of these adults will die between age 30 and 69. Cancer and total deaths due to smoking have fallen so far only in men in high-income countries but will rise globally unless current smokers stop smoking before or during middle age. Higher taxes, regulations on smoking, including 100 % smoke free indoor spaces, and information for consumers could avoid smoking-associated deaths. Irland was 2004 the first country worldwide introducing smoke free bars and restaurants with positive effects on compliance, health of employees and business. In the first year after the introduction these policies have resulted in a 10 - 20 % reduction of acute coronary events. In Switzerland smoke free regulations have been accepted by popular vote first in the canton of Ticino in 2006 and since then in 15 more cantons. The smoking rate dropped from 33 to 27 % since 2001.

This study explores whether pregnant nonsmokers' exposure to environmental tobacco smoke (ETS) affects the average birth weight at term. The population studied consists of pregnant nonsmokers participating in a study called Smoke-free Newborn Study. The participants (n = 1612) answered a questionnaire during 12th to 16th gestational week about their exposure to ETS at home and outside the home. Pregnant nonsmokers exposed to ETS both at home and outside the home gave birth to children with a birth weight of 78.9 g (95% CI -143.7 to -14.1) (P=0.02) lower than the weight of children born to women unexposed to ETS. There was no significant reduction in birth weight among women exposed to ETS at home only or outside the home only. A nonsignificant dose-response association was seen between increasing daily exposure to ETS and reduction in birth weight. Nonsmoking pregnant women who were exposed to ETS at home as well as outside the home gave birth to children with a 79 g reduction in birth weight compared to children of unexposed women. The fact that exposure to ETS has an effect on the birth weight is regarded as essential. The authors recommend that pregnant women should not be exposed to passive smoking, and that it should be considered whether workplace legislation should be instituted in order to protect pregnant women against the adverse effects of passive smoking.

BACKGROUND: Smoking is a potential risk factor for psoriasis. Both psoriasis and smoking habits are partly explained by genetic factors. However, twin studies investigating the association between these traits are limited. METHODS: Questionnaire-based data on smoking habits and psoriasis were...... collected for 34,781 twins, aged 20-71 years, from the Danish Twin Registry. A co-twin control analysis was performed on 1700 twin pairs discordant for lifetime history of smoking. Genetic and environmental correlations between smoking and psoriasis were estimated using classical twin modeling. RESULTS......: After multivariable adjustment, age group (50-71 vs. 20-49 years) and childhood exposure to environmental tobacco smoke (ETS) were significantly associated with psoriasis in the whole population (odds ratio [OR] 1.15, 95% confidence interval [CI] 1.02-1.29 [P = 0.021] and OR 1.28, 95% CI 1.10-1.49 [P...

Results. Ninety-five percent of a total group of 172 OP of Champagne county filled the postal questionnaire. More than 80% of OP's replies identified illegal PSW. The average prevalence of PSW exposure was 0.7% of the total working population. Environmental tobacco smoke (ETS levels were considered between low and medium for most passive smokers (71%. Main features exposure to ETS at work for non-smokers was associated with female gender (69.5%, age between 40 and 49 years (41.2% and belonging to tertiary sector (75.6%. Environmental tobacco smoke exposures at work was firstly in the office for 49.7% of the subjects and secondly in the restroom for 18% of them. Main medical symptoms encountered by non-smokers were respiratory tractus irritation (81.7%. Eighty-three percent of OPs indicated solution to eradicate PSW. Illegal PSW is really weaker than fifteen years ago. However, the findings support a real ban on smoking in the workplace in order to protect all workers.

Epidemiologic studies of companion animals such as dogs have been established as models for the relationship between exposure to environmental tobacco smoke (ETS) and cancer risk in humans. While results from these studies are provocative, pet owner report of a dog's ETS exposure has not yet been validated. We have evaluated the relationship between dog owner's report of household smoking by questionnaire and dog's urinary cotinine level. Between January and October 2005, dog owners presenting their pet for non-emergency veterinary care at the Foster Hospital for Small Animals at Cummings School of Veterinary Medicine, Tufts University, were asked to complete a 10-page questionnaire measuring exposure to household ETS in the previous 24 h and other factors. A free-catch urine sample was also collected from dogs. Urinary cotinine level was assayed for 63 dogs, including 30 whose owners reported household smoking and 33 unexposed dogs matched on age and month of enrollment. Urinary cotinine level was significantly higher in dogs exposed to household smoking in the 24 h before urine collection compared to unexposed dogs (14.6 ng/ml vs. 7.4 ng/ml; P=0.02). After adjustment for other factors, cotinine level increased linearly with number of cigarettes smoked by all household members (P=0.004). Other canine characteristics including age, body composition and nose length were also associated with cotinine level. Findings from our study suggest that household smoking levels as assessed by questionnaire are significantly associated with canine cotinine levels

Smoking in uranium enrichment research building in Tokai Research Establishment, Japan Atomic Energy Research Institute

On the smoking occurred on May 30, 1989 in the uranium enrichment research building, the investigation has been carried out about the presumed cause and the countermeasures for preventing the recurrence, and the following report was presented. In the uranium scrap after the oxidation treatment of vapor-deposited metallic uranium was carried out, a small quantity of unoxidized part having reactivity remained. This unoxidized part existing locally reacts with air in a container, and there is the possibility of generating heat after about one day. In this accident, unoxidized part existed near the wall of a polyethylene vessel, and the oxidation and heat generation reaction advanced. The vessel broke, air supply increased, and heat generation spread. After the temperature reached 300degC, the oxidation of UO 2 to U 3 O 8 took part, thus the polyethylene vessel and others generated smoke. As the countermeasures, for the preservation of uranium scrap, metallic vessels are used, and the atmosphere of inert gas or vacuum is maintained. The uranium scrap containing unoxidized part is rapidly oxidized. The uranium enrichment research building was decontamination. (K.I.)

Smoking cessation in women: findings from qualitative research.

Science.gov (United States)

Puskar, M

1995-11-01

The purpose of this descriptive exploratory study is to describe the experience of successful smoking cessation in adult women. The convenience sample included 10 women, ages 25 to 42, who had abstained from smoking for at least 6 months but not longer than 3 years. A semistructured interview format was used to elicit descriptions of the experience of successful smoking cessation from these subjects. The interview format explored the experience, including initial contemplation, the process of quitting, and maintenance of smoking abstinence. Interviews were audiotaped, transcribed, and then analyzed using methods outlined by Miles and Huberman [1]. Four themes emerged from the data: evolving commitment to health and personal growth, being stigmatized, changing conceptualization of smoking, and smoking cessation as a relational phenomenon. These findings were consistent with Pender's Health Promotion Model and have implications for nurse practitioners who counsel women on smoking cessation.

A number of longitudinal studies have explored the role of friends', parents', and older siblings' smoking in children's smoking acquisition. A reasonable implication of this previous research is that intervention efforts could be beneficially directed toward countering the potential influence of friends' and possibly older siblings' smoking but not parents' smoking. However, methodological limitations of this previous research motivated our reevaluation of the role of friends', parents', and older siblings' smoking in children's smoking. Close friends' smoking status was assessed when children were in 5th grade, whereas parents' and older siblings' smoking status was assessed when children were in 3rd grade. The outcome, children's daily smoking status, was assessed in 12th grade. The setting was 40 Washington state school districts that participated in the long-term Hutchinson Smoking Prevention Project. Participants were the 4,576 families for whom close friends', parents', and older siblings' smoking status as well as children's smoking status were available. The probability that each close friend's smoking influenced the child to smoke daily was 9% (95% CI = 6%-12%), the probability that each parent's smoking influenced the child to smoke daily was 11% (95% CI = 9%-14%), and the probability that each older sibling's smoking influenced the child to smoke daily was 7% (95% CI = 1%-13%). These results suggest that close friends', parents', and siblings' smoking were similarly important influences on children's smoking. Family-focused interventions could be a valuable future direction of prevention research.

Review of hookah tobacco smoking among college students: policy implications and research recommendations.

Gathuru, Irene M; Tarter, Ralph E; Klein-Fedyshin, Michele

2015-01-01

About 30% of college students have smoked hookah tobacco. Although most students perceive this product to be innocuous and non-addictive, hookah tobacco increases the risk for disease and nicotine dependence. Currently, the US Food and Drug Administration (FDA) does not regulate the manufacture, distribution, or sale of hookah tobacco. Empirical literature pertaining to hookah tobacco smoking is reviewed with a focus on the implications for regulatory policy. PubMed, PsycINFO, and Scopus databases were searched to locate articles published in English. The literature search combined several key words including "hookahs", "college", "advertising", "health effects", and "health policy". Smoking hookah tobacco may play a role in the initiation of smoking among tobacco-naïve college students and may portend persistent smoking among those who have smoked cigarettes. College students are typically nondaily, social smokers. They do not perceive that their heightened risk for tobacco diseases and nicotine dependence relates to their smoking behavior. However, few public health messages target college-age adults to counter media messages that endorse hookah tobacco smoking. Given that the FDA is not authorized to ban specific tobacco products, policy actions should focus on the development of effective risk communication strategies that target college-age adults and on limiting the accessibility of hookah tobacco products to these adults. Accordingly, a research agenda that would inform these policy actions is proposed.

This paper aims to analyze the temporal relation between family transitions (partnership formation, first childbirth, separation) and changes in smoking initiation and cessation. We propose a discrete-time logistic model to explore the timing of changes in terms of leads and lags effects up to three years around the event in order to measure both anticipation and adaptation mechanisms. Retrospective biographical data from the Santé et Itinéraires Professionnels (SIP) survey conducted in France in 2006 are used. Partnership formation was followed for both genders by a fall in smoking initiation and an immediate rise in smoking cessation. Childbirth was associated with increased smoking cessation immediately around childbirth, and additionally, females showed an anticipatory increase in smoking cessation up to two years before childbirth. Couple separation was accompanied by an anticipatory increase in smoking initiation for females up to two years prior to the separation, but this effect only occurred in males during separation. Our findings highlight opportunities for more targeted interventions over the life course to reduce smoking, and therefore have relevance for general practitioners and public policy elaboration.

Parental smoking has been identified as the major source of children's exposure to environmental tobacco smoke (ETS). Therefore, parental involvement is critical in ETS exposure prevention programs. This study examined the effects of a parent-child interactive program on reducing children's exposure to ETS at home and enhancing parents' and children's prevention strategies. A clustered randomized controlled trial was administered to 75 families of school-aged children from six primary schools in New Taipei City, Taiwan. Families in the intervention group received a parent-child interactive intervention, and parents in the control group received written materials on tobacco hazards. Data on children's exposure and the prevention of children's exposure to ETS at home were obtained at baseline, 8-week, and 20-week or 6-month assessments. The percentage of children with urine cotinine levels greater than or equal to 6 ng/ml was significantly lower in the intervention group than it was in the control group at both the 8-week and 6-month assessments. The intervention significantly reduced parental smoking in the presence of children and increased parents' prevention of children's ETS exposure and children's ETS avoidance behavior from the baseline to the 20-week assessment. This is a preliminary study design aimed at creating a program for reducing children's ETS exposure at home. Further research to produce evidence supporting the application of the parent-child interactive program in primary schools is suggested. The theoretical basis of the intervention design can serve as a reference for nursing education and the design of health education programs. © The Author 2015.

Exposure to environmental tobacco smoke (ETS) increases the risk of respiratory illness in children but data are inconclusive regarding the risk of IgE sensitisation. To elucidate whether exposure to smoking prenatally and/or postnatally is related to IgE sensitisation in children at 4 years of age. As part of a prospective birth cohort study (BAMSE), a total of 4089 families with children answered questionnaires when the child was 2 months, 1, 2 and 4 years old on environmental factors and symptoms of allergic disease. Blood collected at age 4 years from 2614 children was analysed for IgE antibodies to common inhalant and food allergens. Odds ratios (OR) and 95% confidence intervals (CI) were calculated using logistic regression with adjustments for potential confounders. There was no evident association between maternal smoking during pregnancy and risk of IgE sensitisation. In contrast, a dose-response effect was found for exposure to ETS from parental smoking during the first few months of life and IgE sensitisation. There was an increased risk of sensitisation to inhalant and/or food allergens (OR(adj) 1.28 (95% CI 1.01 to 1.62)) among children exposed to ETS at 2 months of age. The risk appeared particularly elevated for indoor inhalant allergens, such as cat (OR(adj) 1.96 (95% CI 1.28 to 2.99)) and for food allergens (OR(adj) 1.46 (95% CI 1.11 to 1.93)). The IgE sensitising effect of ETS seemed to be confined to infants of parents without allergic diseases and to ETS exposure during early infancy. Our data indicate that exposure in early infancy to ETS increases the risk of IgE sensitisation to indoor inhalant and food allergens.

The home is a significant place for exposure to secondhand smoke for children and non-smoking adults. This study explored factors that would convince families to adopt household smoking bans and actions to create and maintain smoke-free homes. Interviews were conducted with adults in 102 households in rural Georgia. Participating families had a young adolescent and included households with a mix of smokers and non-smokers and smoking ban status. Families reported they would consider a total ban to protect children from secondhand smoke and protect family members if they got sick. Few described difficulties in enforcement with over half of smokers accepting the rules. Situations that made it hard to enforce restrictions were if there was a visitor who smoked, a smoker who had cravings, and bad weather outside when the smoker desired to smoke. Smokers explained that family members could assist them in quitting by talking to them, not purchasing cigarettes for them, not smoking around them, and supporting them. Ideas for promoting smoke-free homes were having a no smoking sign, saying no to visitors who want to smoke, removing ashtrays, and creating a place outside for smokers. These findings can inform interventions designed to create and maintain smoke-free households.

Waterpipe tobacco smoking is a global health concern. Laboratory research has focused on individual waterpipe users while group use is common. This study examined user toxicant exposure and smoke toxicant yield associated with individual and group waterpipe smoking. Twenty-two pairs of waterpipe smokers used a waterpipe individually and as a dyad. Before and after smoking, blood was sampled and expired carbon monoxide (CO) measured; puff topography was recorded throughout. One participant from each pair was selected randomly and their plasma nicotine and expired air CO concentrations were compared when smoking alone to when smoking as part of a dyad. Recorded puff topography was used to machine-produce smoke that was analyzed for toxicant content. There was no difference in mean plasma nicotine concentration when an individual smoked as part of a dyad (mean = 14.9 ng/ml; standard error of the mean [SEM] = 3.0) compared to when smoking alone (mean = 10.0 ng/ml; SEM = 1.5). An individual smoking as part of as a dyad had, on average, lower CO (mean = 15.8 ppm; SEM = 2.0) compared to when smoking alone (mean= 21.3 ppm; SEM = 2.7). When two participants smoked as a dyad they took, on average, more puffs (mean = 109.8; SEM = 7.6) than a singleton smoker (mean = 77.7; SEM = 8.1) and a shorter interpuff interval (IPI; dyad mean = 23.8 seconds; SEM = 1.9; singleton mean = 40.8 seconds; SEM = 4.8). Higher concentrations of several toxicants were observed in dyad-produced smoke. Dyad smoking may increase smoke toxicant content, likely due to the dyad's shorter IPIs and greater puff number. More work is needed to understand if group waterpipe smoking alters the health risks of waterpipe tobacco smoking. This study is the first to measure toxicants in smoke generated from a waterpipe when used by a dyad. Relative to smoke generated by a singleton, dyad smoke had higher concentration of some toxicants. These differences may be attributed to differences in puffing behavior

The results showed that the particle spectrum of the pine smoke powders was unimodal distribution, while it was bimodal for the tung lampblack powders. The average particle size, volume of lampblack powders were about 1/3 and 3% of the pine smoke powders, respectively. But the specific surface area of lampblack particles was 5 times more than the pine smoke particles, which revealed the fact that the lampblack powders were more exquisite than the pine smoke powders .

2005-05-01

Full Text Available Abstract Background Exposure to environmental tobacco smoke (ETS, which contains potent respiratory irritants, may lead to chronic airway inflammation and obstruction. Although ETS exposure appears to cause asthma in children and adults, its role in causing COPD has received limited attention in epidemiologic studies. Methods Using data from a population-based sample of 2,113 U.S. adults aged 55 to 75 years, we examined the association between lifetime ETS exposure and the risk of developing COPD. Participants were recruited from all 48 contiguous U.S. states by random digit dialing. Lifetime ETS exposure was ascertained by structured telephone interview. We used a standard epidemiologic approach to define COPD based on a self-reported physician diagnosis of chronic bronchitis, emphysema, or COPD. Results Higher cumulative lifetime home and work exposure were associated with a greater risk of COPD. The highest quartile of lifetime home ETS exposure was associated with a greater risk of COPD, controlling for age, sex, race, personal smoking history, educational attainment, marital status, and occupational exposure to vapors, gas, dusts, or fumes during the longest held job (OR 1.55; 95% CI 1.09 to 2.21. The highest quartile of lifetime workplace ETS exposure was also related to a greater risk of COPD (OR 1.36; 95% CI 1.002 to 1.84. The population attributable fraction was 11% for the highest quartile of home ETS exposure and 7% for work exposure. Conclusion ETS exposure may be an important cause of COPD. Consequently, public policies aimed at preventing public smoking may reduce the burden of COPD-related death and disability, both by reducing direct smoking and ETS exposure.

Smoking Through a Topography Device Diminishes Some of the Acute Rewarding Effects of Smoking.

Science.gov (United States)

Ross, Kathryn C; Juliano, Laura M

2016-05-01

Smoking topography (ST) devices are an important methodological tool for quantifying puffing behavior (eg, puff volume, puff velocity) as well as identifying puffing differences across individuals and situations. Available ST devices are designed such that the smoker's mouth and hands have direct contact with the device rather than the cigarette itself. Given the importance of the sensorimotor aspects of cigarette smoking in smoking reward, it is possible that ST devices may interfere with the acute rewarding effects of smoking. Despite the methodological importance of this issue, few studies have directly compared subjective reactions to smoking through a topography device to naturalistic smoking. Smokers (N = 58; 38% female) smoked their preferred brand of cigarettes one time through a portable topography device and one time naturalistically, in counterbalanced order across two laboratory sessions. Smoking behavior (eg, number of puffs) and subjective effects (eg, urge reduction, affect, smoking satisfaction) were assessed. Negative affect reduction was greater in the natural smoking condition relative to the topography condition, but differences were not significant on measures of urge, withdrawal, or positive affect. Self-reported smoking satisfaction, enjoyment of respiratory tract sensations, psychological reward, craving reduction, and other rewarding effects of smoking were also significantly greater in the naturalistic smoking condition. The effects of using a ST device on the smoking experience should be considered when it is used in research as it may diminish some of the rewarding effects of smoking. When considering the inclusion of a smoking topography device in one's research, it is important to know if use of that device will alter the smoker's experience. This study assessed affective and subjective reactions to smoking through a topography device compared to naturalistic smoking. We found that smoking satisfaction, psychological reward, enjoyment

The association between environmental tobacco smoke (ETS) and asthma symptoms is well documented, but a causal relationship is inconclusive. International Study of Asthma and Allergies in Childhood (ISAAC) Phase Three was the first to report a dose-response relationship between current wheezing and exposure to parental cigarette smoke. As exposure of children to water pipe (narghile) smoke is of concern in Syria, in the ISAAC Phase Three Tartous Centre we also examined the role of parental smoking of the narghile. Parents of children aged 6-7 years completed core written questionnaires about the prevalence of symptoms, and an environmental questionnaire for other risk factors, including parental cigarette smoking. We added questions about narghile to the questionnaire. Among 2 734 pupils (49% females) surveyed, we found an association between exposure to ETS of the mother smoking cigarette or narghile and ever wheezing, nocturnal cough and severe wheeze; however, the strongest association was found when the mother smoked narghile. Mother smoking narghile was also associated with exercise wheeze. Father smoking narghile, but not cigarettes, was associated with nocturnal cough, severe wheeze and exercise wheeze. The association with current wheeze became significant when mother smoked both cigarettes and narghile; however, the effect was addititive and not synergic. We recommend that international studies investigating ETS include questions on narghile smoking.

Environmental tobacco smoke exposure (ETS) is a significant risk factor for the development of many diseases, including lung cancer, lower respiratory tract infections, asthma and eye, throat and nasal irritations. Hospitality workers form an occupational group with high exposure to ETS in their workplace. Taking into account the health consequences of ETS exposure and high prevalence of exposure in public places, including workplaces, many countries have implemented the smoking ban that prohibits or restricts smoking in workplaces, including restaurants and bars. The epidemiological studies have indicated a significant reduction in the exposure level after implementation of the smoking ban. Most studies have also indicated a significant reduction in respiratory and sensory symptoms. The impact of the smoking ban on the lung function measurements is still not clear.

Effects of interactive transport and scavenging of smoke on the calculated temperature change resulting from large amounts of smoke

International Nuclear Information System (INIS)

MacCracken, M.C.; Walton, J.J.

1984-12-01

Several theoretical studies with numerical models have shown that substantial land-surface cooling can occur if very large amounts (approx. 100 x 10 12 = 100 Tg) of highly absorbing sooty-particles are injected high into the troposphere and spread instantaneously around the hemisphere (Turco et al., 1983; Covey et al. 1984; MacCracken, 1983). A preliminary step beyond these initial calculations has been made by interactively coupling the two-layer, three-dimensional Oregon State University general circulation model (GCM) to the three-dimensional GRANTOUR trace species model developed at the Lawrence Livermore National Laboratory. The GCM simulation includes treatment of tropospheric dynamics and thermodynamics and the effect of soot on solar radiation. The GRANTOUR simulation includes treatment of particle transport and scavenging by precipitation, although no satisfactory verification of the scavenging algorithm has yet been possible. We have considered the climatic effects of 150 Tg (i.e., the 100 Mt urban war scenario from Turco et al., 1983) and of 15 Tg of smoke from urban fires over North America and Eurasia. Starting with a perpetual July atmospheric situation, calculation of the climatic effects as 150 Tg of smoke are spread slowly by the winds, rather than instantaneously dispersed as in previous calculations, leads to some regions of greater cooling under the denser parts of the smoke plumes and some regions of less severe cooling where smoke arrival is delayed. As for the previous calculations, mid-latitude decreases of land surface air temperature for the 150 Tg injection are greater than 15 0 C after a few weeks. For a 15 Tg injection, however, cooling of more than several degrees centigrade only occurs in limited regions under the dense smoke plumes present in the first few weeks after the injection. 10 references, 9 figures

Achieving Smoke-Free Mental Health Services: Lessons from the Past Decade of Implementation Research

Directory of Open Access Journals (Sweden)

Jonathan Campion

2013-09-01

Full Text Available The culture of smoking by patients and staff within mental health systems of care has a long and entrenched history. Cigarettes have been used as currency between patients and as a patient management tool by staff. These settings have traditionally been exempt from smoke-free policy because of complex held views about the capacity of people with mental disorder to tolerate such policy whilst they are acutely unwell, with stakeholders’ continuing fierce debate about rights, choice and duty of care. This culture has played a significant role in perpetuating physical, social and economic smoking associated impacts experienced by people with mental disorder who receive care within mental health care settings. The past decade has seen a clear policy shift towards smoke-free mental health settings in several countries. While many services have been successful in implementing this change, many issues remain to be resolved for genuine smoke-free policy in mental health settings to be realized. This literature review draws on evidence from the international published research, including national audits of smoke-free policy implementation in mental health units in Australia and England, in order to synthesise what we know works, why it works, and the remaining barriers to smoke-free policy and how appropriate interventions are provided to people with mental disorder.

Full Text Available Background: Smoking cessation research output should move beyond descriptive research of the health problem to testing interventions that can provide causal data and effective evidence-based solutions. This review examined the number and type of published smoking cessation studies conducted in low-socioeconomic status (low-SES and disadvantaged population groups. Methods: A systematic database search was conducted for two time periods: 2000–2004 (TP1 and 2008–2012 (TP2. Publications that examined smoking cessation in a low-SES or disadvantaged population were coded by: population of interest; study type (reviews, non-data based publications, data-based publications (descriptive, measurement and intervention research; and country. Intervention studies were coded in accordance with the Cochrane Effective Practice and Organisation of Care data collection checklist and use of biochemical verification of self-reported abstinence was assessed. Results: 278 citations were included. Research output (i.e., all study types had increased from TP1 27% to TP2 73% (χ² = 73.13, p < 0.001, however, the proportion of data-based research had not significantly increased from TP1 and TP2: descriptive (TP1 = 23% vs. TP2 = 33% or intervention (TP1 = 77% vs. TP2 = 67%. The proportion of intervention studies adopting biochemical verification of self-reported abstinence had significantly decreased from TP1 to TP2 with an increased reliance on self-reported abstinence (TP1 = 12% vs. TP2 = 36%. Conclusions: The current research output is not ideal or optimal to decrease smoking rates. Research institutions, scholars and funding organisations should take heed to review findings when developing future research and policy.

Serum cotinine levels are a reliable marker of tobacco use. Few studies have validated questionnaires assessing smoking and exposure to environmental tobacco smoke (ETS) against serum levels. We undertook such a study in industrial workers in India. We chose 426 individuals by stratified random sampling from a database of 3397 individuals surveyed at New Delhi for the cardiovascular disease surveillance programme in a large industrial setting. Questionnaires assessing details of smoking practices and duration of exposure to ETS (if any) were administered. Cotinine levels were measured in the blood samples of these individuals. The study population comprised 142 nonsmokers not exposed to ETS, 142 non-smokers exposed to ETS and 142 active smokers. Cotinine levels among nonsmokers not exposed to ETS were non-detectable; and for non-smokers exposed to ETS and active smokers, the median (interquartile range) levels were non-detectable (non-detectable to 46.1 ng/ml) and 336 ng/ml (204-500 ng/ml), respectively. The best combined sensitivity (91%) and specificity (87.2%) yielded a cotinine cut-off level of 40.35 ng/ml to differentiate active smokers from non-smokers not exposed to ETS and those exposed to ETS (area under the curve 0.902). The cut-off cotinine level was estimated at 10.95 ng/ml using a similar analysis (sensitivity 43%, specificity 82%; area under the curve 0.64) to distinguish non-smokers not exposed to ETS from those exposed to ETS. The misclassification rate was estimated at 19% and 57.1% among self-reported non-smokers not exposed to ETS and those exposed to ETS, respectively. Obtaining a history of tobacco use is an accurate method of detecting smokers in epidemiological studies whereas serum cotinine levels accurately differentiate smokers from non-smokers. However, a brief questionnaire assessing passive exposure to smoke has poor sensitivity in distinguishing non-smokers exposed to ETS from those not exposed to ETS.

The home is a significant place for exposure to secondhand smoke for children and non-smoking adults. This study explored factors that would convince families to adopt household smoking bans and actions to create and maintain smoke-free homes. Interviews were conducted with adults in 102 households in rural Georgia. Participating families had a young adolescent and included households with a mix of smokers and non-smokers and smoking ban status. Families reported they would consider a total b...

(1) BACKGROUND: The home environment is a major source of Environmental Tobacco Smoke (ETS) exposure among children especially in early childhood. ETS exposure is an important health risk among children and can cause severe and chronic diseases, such as asthma, bronchitis, and premature death. However, ETS exposure at home has often been neglected in the Chinese families. Identification of factors that facilitate or otherwise hamper the adoption of home smoking ban will help in the design and implementation of evidence-based intervention programs. This study identifies factors correlated with home smoking bans in Chinese families with children. (2) METHODS: A cross-sectional survey of parents living in Nanning city, Guangxi Province, China with at least one smoker and a child in the household was conducted between September, 2013 and January, 2014. A Chi-square test was used to compare categorical variables differences between the parents who had home smoking bans and those with no home smoking ban. Multiple logistic regression analyses were used to identify factors correlated with home smoking bans. (3) RESULTS: 969 completed questionnaires were collected with a response rate of 92.29% (969/1050). Of the respondents (n = 969), 14.34% had complete home smoking bans. Factors that were associated with home smoking bans were: having no other smokers in the family (OR = 2.173), attaining education up to high school (OR = 2.471), believing that paternal smoking would increase the risk of lower respiratory tract illnesses (OR = 2.755), perceiving the fact that smoking cigarettes in the presence of the child will hurt the child's health (OR = 1.547), believing that adopting a no smoking policy at home is very important (OR = 2.816), and being confident to prevent others to smoke at home (OR = 1.950). Additionally, parents who perceived difficulty in adopting a no smoking policy at home would not have a home smoking ban (OR = 0.523). (4) CONCLUSIONS: A home smoking ban is

An inability to maintain abstinence is a key indicator of tobacco dependence. Unfortunately, little evidence exists regarding the ability of the major tobacco dependence measures to predict smoking cessation outcome. This paper used data from four placebo-controlled smoking cessation trials and one international epidemiologic study to determine relations between the Fagerström Test for Nicotine Dependence (FTND; Heatherton et al., 1991), the Heaviness of Smoking Index (HSI; Kozlowski et al., 1994), the Nicotine Dependence Syndrome Scale (NDSS; Shiffman et al., 2004) and the Wisconsin Inventory of Smoking Dependence Motives (WISDM; Piper et al. 2004) with cessation success. Results showed that much of the predictive validity of the FTND could be attributed to its first item, time to first cigarette in the morning, and this item had greater validity than any other single measure. Thus, the time to first cigarette item appears to tap a pattern of heavy, uninterrupted, and automatic smoking and may be a good single-item measure of nicotine dependence. PMID:18067032

Full Text Available Abstract Background Acute respiratory illness (ARI is the most common cause of acute presentations and hospitalisations of young Indigenous children in Australia and New Zealand (NZ. Environmental tobacco smoke (ETS from household smoking is a significant and preventable contributor to childhood ARI. This paper describes the protocol for a study which aims to test the efficacy of a family-centred tobacco control program about ETS to improve the respiratory health of Indigenous infants in Australia and New Zealand. For the purpose of this paper 'Indigenous' refers to Australia's Aboriginal and Torres Strait Islander peoples when referring to Australian Indigenous populations. In New Zealand, the term 'Indigenous' refers to Māori. Methods/Design This study will be a parallel, randomized, controlled trial. Participants will be Indigenous women and their infants, half of whom will be randomly allocated to an 'intervention' group, who will receive the tobacco control program over three home visits in the first three months of the infant's life and half to a control group receiving 'usual care' (i.e. they will not receive the tobacco control program. Indigenous health workers will deliver the intervention, the goal of which is to reduce or eliminate infant exposure to ETS. Data collection will occur at baseline (shortly after birth and when the infant is four months and one year of age. The primary outcome is a doctor-diagnosed, documented case of respiratory illness in participating infants. Discussion Interventions aimed at reducing exposure of Indigenous children to ETS have the potential for significant benefits for Indigenous communities. There is currently a dearth of evidence for the effect of tobacco control interventions to reduce children's exposure to ETS among Indigenous populations. This study will provide high-quality evidence of the efficacy of a family-centred tobacco control program on ETS to reduce respiratory illness. Outcomes of

Environmental tobacco smoke and low birth weight: a hazard in the workplace?

Low birth weight (LBW) increases infant morbidity and mortality worldwide. One well-established risk factor is maternal smoking. Environmental tobacco smoke (ETS) exposure has recently been focused on as another potential risk factor. In this article, we review epidemiologic literature on the effects of ETS on LBW and intrauterine growth retardation (IUGR), the cause of LBW related to maternal smoking. As we consider the feasibility of modifying women's exposure, we focus our discussion on workplace exposure to ETS. The workplace is particularly important to consider because women of child-bearing age are present in the workplace in greater numbers now than ever before. In addition, certain subgroups of working women may be particularly at risk from the effects of ETS on pregnancy because they work in environments with higher exposure or they are more susceptible to its effects. We conclude that there is consistent evidence to relate maternal ETS exposure to an increased risk of adverse pregnancy outcomes and that this association may be generalized to the work environment. In studies with positive findings, infants exposed to ETS antenatally were 1.5-4 times more likely to be born with LBW, but few studies examined LBW. Most studies looked at measures of IUGR. ETS was associated with reductions in birth weight (adjusted for gestational age) ranging from 25 to 90 g. Infants born to women exposed to ETS were generally 2-4 times more likely to be born small-for-gestational age. ETS exposure in the workplace can and should be minimized to protect pregnant women from its adverse effects.

To reverse the present stagnation in progress toward reduced smoking rates, new widely accessible treatment methods for smoking cessation must be developed and evaluated with large groups of smokers. We tested the feasibility of conducting a smoking cessation study over the Internet using a brief, self-help educational intervention. Through a direct e-mail sent from a large health information web site (WebMD), and with our presence on the Internet, we recruited 538 adult smokers to the study. Most participants (90.5%) completed all baseline questionnaires. Questionnaires showed acceptable to good reliability and were comparable with studies using paper-and-pencil methods. Participants appeared to be highly dependent on nicotine. Forty-two percent indicated being ready to quit smoking at baseline. At 1-month follow-up, 42.8% of baseline participants returned a complete follow-up questionnaire, 40% of whom indicated having made a serious quit attempt, and 8.3% of whom indicated 7-day abstinence. Most follow-up participants rated the site as at least somewhat helpful to quitting (74.9%) and reported at least a slight increased intention to quit smoking over baseline (67.3%). While Internet-enabled self-help interventions for smoking cessation are able to reach large numbers of smokers interested in quitting smoking, additional procedures are needed to retain these users for treatment and follow-up assessments.

Context A number of studies report an association between maternal smoking during pregnancy and offspring conduct disorder. However, past research evidences difficulty disaggregating prenatal environmental from genetic and postnatal environmental influences. Objective To examine the relationship between maternal smoking during pregnancy and offspring conduct problems among children reared by genetically-related and genetically-unrelated mothers. Design, Setting and Participants Three studies employing distinct but complementary research designs were utilized: The Christchurch Health and Development Study (a longitudinal cohort study that includes biological and adopted children), the Early Growth and Development Study (a longitudinal adoption at birth study), and the Cardiff IVF Study (genetically-related and -unrelated families; an adoption at conception study). Maternal smoking during pregnancy was measured as the average number of cigarettes/day (0, 1–9 or 10+) smoked during pregnancy. A number of possible covariates (child gender, ethnicity, birth weight, breast feeding, maternal age at birth, maternal education, family SES, family breakdown, placement age, and parenting practices) were controlled in the analyses. Main Outcome Measure Child conduct problems (age 4–10 years) reported by parents and/or teachers using the Rutter and Conners behaviour scales, the Child Behavior Checklist and Children's Behavior Questionnaire, and the Strengths and Difficulties Questionnaire. Results A significant association between maternal smoking during pregnancy and child conduct problems was observed among children reared by genetically-related and genetically-unrelated mothers. Results from a meta-analysis affirmed this pattern of findings across pooled study samples. Conclusions Findings across the three studies using a complement of genetically-sensitive research designs suggest smoking during pregnancy is a prenatal risk factor for offspring conduct problems, when

The European Union Emissions Trading Scheme (EU ETS) is supposed to be an important mechanism for addressing climate change. Up to now, the theoretical foundation of EU ETS has been widely acknowledged, but empirical research on its current situation has only been published recently or is forthcoming. Therefore, this paper is aimed to summarize the main arguments of empirical studies on the EU ETS, in terms of two aspects, i.e., the operating mechanism and economic effect of the EU ETS, which are two crucial topics and have been attached much attention. Based on the shortcomings of current research and future requirements of the EU ETS evolution, finally, we also present some further directions of the EU ETS research. Overall, the research overview here may be helpful to recognize the features of the EU ETS and its effect on others. (author)

Short-term measurement of suspended particulate matter has been recently made possible since the release of laser-operating portable instruments. Data of a pilot study of field evaluation of environmental tobacco smoke (ETS) with a portable instrument are reported. We analysed the concentrations of total suspended particle (TSP) and of the fine particles PM10, PM7, PM2.5 and PM1 released indoor from a single cigarette, and their levels inside smoking- and non-smoking-areas of a restaurant. The results indicate that ETS creates high level indoor particulate pollution, with concentrations of PM10 exceeding air quality standards. This kind of field evaluation could allow a more careful assessing of short-term exposure to ETS and its relevance to public health.

Full Text Available Abstract Background Studies on the associations between smoking and allergic diseases have mostly focused on asthma. Epidemiological studies in adults on the effects of smoking on allergic diseases other than asthma, such as eczema and rhinoconjunctivitis, have been limited, and the information that is available has been inconsistent. The aim of this study was to investigate the association between smoking status and environmental tobacco smoke (ETS exposure and the prevalence of allergic diseases. Methods Study subjects were 1743 pregnant Japanese women. The definitions of wheeze and asthma were based on criteria from the European Community Respiratory Health Survey whereas those of eczema and rhinoconjunctivitis were based on criteria from the International Study of Asthma and Allergies in Childhood. Adjustment was made for age; region of residence; family history of asthma, atopic eczema, and allergic rhinitis; household income; and education. Results Compared with never smoking, current smoking and ≥ 4 pack-years of smoking were independently positively associated with the prevalence of wheeze. There were no associations between smoking status and the prevalence of asthma, eczema, or rhinoconjunctivitis. When subjects who had never smoked were classified into four categories based on the source of ETS exposure (never, only at home, only at work, and both, exposure occurring both at home and at work was independently associated with an increased prevalence of two outcomes: wheeze and rhinoconjunctivitis. No relationships were observed between exposure to ETS and the prevalence of asthma or eczema. Conclusions Our results provide evidence that current smoking and ETS exposure may increase the likelihood of wheeze. The possibility of a positive association between ETS exposure and rhinoconjunctivitis was also suggested.

Effects of anti-smoking advertising on youth smoking: a review.

2003-01-01

This paper reviews empirical studies, encompassing community trials and field experiments, and evaluates government-funded anti-smoking campaigns, ecologic studies of population impact of anti-smoking advertising, and qualitative studies that have examined the effects of anti-smoking advertising on teenagers. We conclude that anti-smoking advertising appears to have more reliable positive effects on those in pre-adolescence or early adolescence by preventing commencement of smoking. It is unclear whether this is due to developmental differences, or is a reflection of smoking experience, or a combination of the two. In addition, it is evident that social group interactions, through family, peer and cultural contexts, can play an important role in reinforcing, denying, or neutralizing potential effects of anti-smoking advertising. Although there is some research to suggest that advertising genres that graphically depict the health effects of smoking, emphasize social norms against smoking, and portray the tobacco industry as manipulative can positively influence teenagers, these findings are far from consistent. Finally, the effects of anti-smoking advertising on youth smoking can be enhanced by the use of other tobacco control strategies, and may be dampened by tobacco advertising and marketing. Overall, the findings of this review indicate that there is no single "recipe" for anti-smoking advertising that leads to reductions in youth smoking. Anti-smoking advertising can influence youth smoking, but whether it does in the context of individual anti-smoking campaigns needs to be the subject of careful evaluation.

Video games are played by a majority of adolescents, yet little is known about whether and how video games are associated with smoking behavior and attitudes. This systematic review examines research on the relationship between video games and smoking. We searched MEDLINE, psycINFO, and Web of Science through August 20, 2014. Twenty-four studies met inclusion criteria. Studies were synthesized qualitatively in four domains: the prevalence and incidence of smoking imagery in video games (n = 6), video game playing and smoking behavior (n = 11), video game addiction and tobacco addiction (n = 5) and genre-specific game playing and smoking behavior (n = 3). Tobacco content was present in a subset of video games. The literature is inconclusive as to whether exposure to video games as a single construct is associated with smoking behavior. Four of five studies found an association between video game addiction and smoking. For genre-specific game playing, studies suggest that the type of game played affected association with smoking behavior. Research on how playing video games influences adolescents' perceptions of smoking and smoking behaviors is still in its nascence. Further research is needed to understand how adolescents respond to viewing and manipulating tobacco imagery, and whether engaging in game smoking translates into changes in real-world attitudes or behavior. Smoking imagery in video games may contribute to normalizing adolescent smoking. A large body of research has shown that smoking imagery in a variety of media types contributes to adolescent smoking uptake and the normalization of smoking behavior, and almost 90% of adolescents play video games, yet there has never been a published systematic review of the literature on this important topic. This is the first systematic review to examine the research on tobacco and video games.We found that tobacco imagery is indeed present in video games, the relationship between video game playing and smoking

Second-Hand Smoke Increases Bronchial Hyperreactivity and Eosinophilia in a Murine Model of Allergic Aspergillosis

Full Text Available Involuntary inhalation of tobacco smoke has been shown to aggravate the allergic response. Antibodies to fungal antigens such as Aspergillus fumigatus (Af cause an allergic lung disease in humans. This study was carried out to determine the effect of environmental tobacco smoke (ETS on a murine model of allergic bronchopulmonary aspergillosis (ABPA. BALB/c mice were exposed to aged and diluted sidestream cigarette smoke to simulate 'second-hand smoke'. The concentration was consistent with that achieved in enclosed public areas or households where multiple people smoke. During exposure, mice were sensitized to Af antigen intranasally. Mice that were sensitized to Af antigen and exposed to ETS developed significantly greater airway hyperreactivity than did mice similarly sensitized to Af but housed in ambient air. The effective concentration of aerosolized acetylcholine needed to double pulmonary flow resistance was significantly lower in Af + ETS mice compared to the Af + AIR mice. Immunological data that supports this exacerbation of airway hyperresponsiveness being mediated by an enhanced type 1 hypersensitivity response include: eosinophilia in peripheral blood and lung sections. All Af sensitized mice produced elevated levels of IL4, IL5 and IL10 but no IFN-γ indicating a polarized Th2 response. Thus, ETS can cause exacerbation of asthma in ABPA as demonstrated by functional airway hyperresponsiveness and elevated levels of blood eosinophilia.

Smoking in Hollywood movies: impact on teen smoking with special reference to German adolescents.

2007-01-01

This paper summarizes studies that have linked exposure to movie smoking and smoking initiation among adolescents. Much of the research linking exposure to smoking to movies with adolescent smoking comes from studies of U.S. children and their exposure to smoking in Hollywood movies. Cross-sectional and longitudinal studies have assessed such exposure and have found a strong, independent association with smoking onset. A first study conduced in Germany reveals that smoking in internationally distributed movies is a risk factor for ever and current smoking among European adolescents, too. It is concluded that limiting exposure of young adolescents to movie smoking could have important world-wide public health implications.

The extension of pollutant accumulation in plant leaves associated with its genotoxicity is a common approach to predict the quality of outdoor environments. However, this approach has not been used to evaluate the environmental quality of outdoor smoking areas. This study aims to evaluate the effects of environmental tobacco smoke (ETS) by assessing particulate matter 2.5 μm (PM 2.5 ) levels, the pollen abortion assay, and trace elements accumulated in plant leaves in an outdoor smoking area of a hospital. For this, PM 2.5 was measured by active monitoring with a real time aerosol monitor for 10 days. Eugenia uniflora trees were used for pollen abortion and accumulated element assays. Accumulated elements were also assessed in Tradescantia pallida leaves. The median concentration of PM 2.5 in the smoking area in all days of monitoring was 66 versus 34 μg/m 3 in the control area (P Eugenia uniflora were in higher concentration in the smoking area when compared to control area. Smoking area also showed higher rate of aborted grains (26.1 ± 10.7 %) compared with control (17.6 ± 4.5 %) (P = 0.003). Under the study conditions, vegetal biomonitoring proved to be an effective tool for assessing ETS exposure in outdoor areas. Therefore, vegetal biomonitoring of ETS could be a complement to conventional analyses and also proved to be a cheap and easy-handling tool to assess the risk of ETS exposure in outdoor areas.

Veterans comprise a large segment of the U.S. population and smoke at high rates. One significant way to reduce healthcare costs and improve the health of veterans is to reduce smoking-related illnesses for smokers who have high smoking rates and/or face disproportionate smoking consequences (e.g. women, racial/ethnic minorities, sexual orientation minorities). We reviewed published studies of smoking behavior in three demographic subgroups of veterans - women, racial/ethnic minorities, and sexual orientation minorities - to synthesize current knowledge and identify areas in need of more research. A MEDLINE search identified papers on smoking and veterans published through 31 December 2014. Twenty-five studies were identified that focused on gender (n = 17), race/ethnicity (n = 6), or sexual orientation (n = 2). Female and sexual orientation minority veterans reported higher rates of smoking than non-veteran women and sexual orientation majority veterans, respectively. Veterans appeared to be offered VA smoking cessation services equally by gender and race. Few studies examined smoking behavior by race/ethnicity or sexual orientation. Little information was identified examining the outcomes of specific smoking treatments for any group. There is a need for more research on all aspects of smoking and quit behavior for women, racial/ethnic minorities, and sexual orientation minority veterans. The high rates of smoking by these groups of veterans suggest that they may benefit from motivational interventions aimed at increasing quit attempts and longer and more intense treatments to maximize outcomes. Learning more about these veterans can help reduce costs for those who experience greater consequences of smoking.

Exposure to secondhand smoke is problematic for residents living in multiunit housing, as the smoke migrates through shared ventilation systems, unsealed cracks, and door spaces. The objective of our research was to assess resident exposure to secondhand smoke, support for no-smoking policies, and the health impacts of no-smoking policies in multiunit housing. Surveys of 312 heads of households who resided in 1 of 3 multiunit buildings managed by a Colorado public housing authority were administered before and after implementation of a no-smoking policy that prohibited smoking in all resident apartments and all indoor common areas. A matched-pairs analysis of initial surveys and 15-month post-policy implementation surveys for 115 respondents was conducted. Decreases were found in the number and percentage of smokers who smoked every day and the number of cigarettes smoked per day, and 30% had quit smoking 15 months after policy implementation. The percentage of residents who smelled secondhand smoke indoors declined significantly. A significant decrease in breathing problems was found after policy implementation. Although decreases were found in the incidence of asthma attacks, emphysema/chronic obstructive pulmonary disease, eye irritation, colds, nasal congestion, and ear/sinus infections, these decreases were not significant. Consistent findings across nearly all variables tested suggest that no-smoking policies reduce resident exposure to secondhand smoke, lower the incidence of secondhand smoke-associated breathing problems, decrease daily smoking and cigarette consumption, encourage smoking cessation, and increase quit attempts. If implemented in all multiunit housing, these policies could reduce exposure to secondhand smoke and health problems associated with secondhand smoke, promote smoking cessation, and reduce cigarette consumption.

Hospitality workers are a population particularly at risk from the noxious effects of environmental tobacco smoke (ETS). The Canton of Vaud, Switzerland banned smoking in public places in September 2009. This prospective study addresses the impact of the ban on the health of hospitality workers. ETS exposure was evaluated using a passive sampling device that measures airborne nicotine; lung function was assessed by spirometry; health-related quality of life, ETS exposure symptoms and satisfaction were measured by questionnaire. 105 participants (smokers and non-smokers) were recruited initially and 66 were followed up after one year. ETS exposure was significantly lower after the ban. Hospitality workers had lower pre-ban forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) values than expected. FEV1 remained stable after the ban, with a near-significant increase in the subgroup of asthmatics only. FVC increased at one year follow-up from 90.42% to 93.05% (p = 0.02) in the entire cohort; women, non-smokers and older participants gained the greatest benefit. The health survey showed an increase in physical wellbeing after the ban, the greatest benefit being observed in non-smokers. ETS exposure symptoms were less frequent after the ban, especially red and irritated eyes and sneezing. The new law was judged useful and satisfactory by the vast majority of employees, including smokers. The recent cantonal ban on smoking in public places brought about an improvement in lung function, physical well-being and ETS symptoms of hospitality workers, including smokers.

To analyze the perception of parents about secondhand smoking in their children's health. Ethnographic qualitative and quantitative study. We sought the point of view and understanding of the parents that were active smokers in relation to environmental tobacco smoke (ETS) and secondhand smoking. Mothers and fathers who are active smokers and that live with their children from seven different public schools in the city of Anápolis, Midwest Brazil, were interviewed in the first semester of in a reserved room in the schools. A descriptive and qualitative analysis was carried out through the ethnography. 58 parents with an average time of smoking of 15.3 years and an average quantity of cigarettes smoked per day of 2 were interviewed. Among them, 59% didn't know what ETS was, and 60% stated knowing what a secondhand smoker was. However, when questioned about their children as secondhand smokers, 52% didn't consider them to be. Some parents knew some of the effects of secondhand smoking in the health of their children. However, the majority (52%) of them did not believe that their children would suffer any respiratory impairment or did not know about these impairments. Children were exposed to Environmental Tobacco Pollution in their residence if one considers parental duration of smoking and average of cigarettes smoked per day. There was a lack of knowledge of the parents about ETS, secondhand smoking and the evils that cigarettes could cause in the health of their children.

Despite epidemiologic, experimental and observational data on the association of environmental tobacco smoke (ETS) and adverse health effects, bar and restaurant workers remain exposed to ETS in the majority of states and countries. Three public health surveillance systems were used to identify and conduct a follow-up investigation of a reported acute asthma death of a young waitress in a bar. The waitress collapsed at the bar where she worked and was declared dead shortly thereafter. Evaluation of the circumstances of her death and her medical history concluded that her death was from acute asthma due to environmental tobacco smoke at work. This is the first reported acute asthma death associated with work-related ETS. Recent studies of asthma among bar and restaurant workers before and after smoking bans support this association. This death dramatizes the need to enact legal protections for workers in the hospitality industry from secondhand smoke.

Environmental tobacco smoke (ETS) has received considerable attention because of its contribution to indoor air pollution. While some studies have attempted to estimate the exposure of humans to ETS constituents by extrapolating from information gleaned from investigations of sidestream smoke (SS), few studies have reported a direct comparison between the composition of SS and that of ETS. In the study reported here, the authors describe the relative compositional similarities and differences between the vapor phase of SS and that of ETS. SS was generated under different conditions. Both a new laminar flow chamber, which prevents significant alteration of the near-cigarette environment, and a modified Neurath chamber were used for SS generation. ETS samples were collected from an office environment. Vapor phase samples were collected on multi-media resin sorbent traps and analyzed using thermal desorption gas/liquid chromatography employing flame ionization, nitrogen-specific, and mass selective detection. Influences on the compositional profiles by the manner in which the SS is generated are described, as well as the differences between SS and ETS composition resulting from phase transition

Reflections on 30+ years of smoking cessation research: from the individual to the world.

Science.gov (United States)

Lando, Harry A

2006-01-01

This is a personal retrospective in which I describe my career as a smoking cessation researcher and place cessation into an overall perspective of tobacco reduction. I spent approximately the first 15 years focusing primarily upon small group approaches to cessation emphasising relatively intensive behavioural interventions. It became apparent, however, that these types of approaches in isolation, even if broadly disseminated, would have relatively minimal impact on overall tobacco use. In part because I became discouraged with the potential of group programmes to reduce overall smoking prevalence, I began to focus more on population-based studies, especially in the context of 'teachable moments' including pregnancy, hospitalisation, forced abstinence in the military and existing smoking-related disease. I became concerned especially with the fact that there has been relatively little work with hard-core medically compromised smokers. It also became apparent that promoting cessation would be most likely to be effective with a comprehensive evidence-based tobacco reduction strategy including school and community-based prevention programmes, enforcement of ordinances restricting minors' access to tobacco, restrictions on tobacco advertising and promotion, counter advertising and strong smoke-free policies. In recent years I have become very concerned about the overall global tobacco epidemic and the projections of dramatically increasing tobacco morbidity and mortality in developing countries. I am now devoting my primary career emphasis to global tobacco reduction initiatives, including cessation research in India and Indonesia, cessation as part of broader tobacco reduction strategies and networking to increase resources and emphasis devoted to global tobacco reduction.

2012-11-01

The aim of the PROMIS® Smoking Initiative is to develop, evaluate, and standardize item banks to assess cigarette smoking behavior and biopsychosocial constructs associated with smoking for both daily and non-daily smokers. We used qualitative methods to develop the item pool (following the PROMIS® approach: e.g., literature search, "binning and winnowing" of items, and focus groups and cognitive interviews to finalize wording and format), and quantitative methods (e.g., factor analysis) to develop the item banks. We considered a total of 1622 extant items, and 44 new items for inclusion in the smoking item banks. A final set of 277 items representing 11 conceptual domains was selected for field testing in a national sample of smokers. Using data from 3021 daily smokers in the field test, an iterative series of exploratory factor analyses and project team discussions resulted in six item banks: Positive Consequences of Smoking (40 items), Smoking Dependence/Craving (55 items), Health Consequences of Smoking (26 items), Psychosocial Consequences of Smoking (37 items), Coping Aspects of Smoking (30 items), and Social Factors of Smoking (23 items). Inclusion of a smoking domain in the PROMIS® framework will standardize measurement of key smoking constructs using state-of-the-art psychometric methods, and make them widely accessible to health care providers, smoking researchers and the large community of researchers using PROMIS® who might not otherwise include an assessment of smoking in their design. Next steps include reducing the number of items in each domain, conducting confirmatory analyses, and duplicating the process for non-daily smokers. Copyright © 2012 Elsevier Ltd.

Objective To study the effect of cigarette smoke exposure on the expression of endothelin 2 (ET-2) in bronchial epithelium of asthmatic rats. Methods Asthma models were established through intraperitoneal injection of 1 mL chicken ovalbumin (OVA)/Al(OH) 3 mixture (asthma model group, n=6); based on the asthma models, exposure to smoking gas lasted four weeks with 10 cigarettes per day (smoke-exposed asthma group, n=6); based on the smoke-exposed asthma models, the rats were treated with intraperitoneal injection of dexamethasone 2 mg/(kg.d), intragastric administration of ET receptor inhibitor bosentan 100 mg/(kg.d) and combined use, respectively named dexamethasone treated group, bosentan treated group, and dexamethasone-bosentan treated group, 6 rats in every group. What's more, other 6 rats were only subjected to intraperitoneal injection of 1 mL normal saline as normal controls; in addition to the injection of saline, cigarette smoke control group (n=6) was set up by the exposure to smoking gas for four weeks with 10 cigarettes per day. Bronchoalveolar lavage fluid (BALF) was collected from the upper lobe of the left lung for cell counting and classification. Pathological changes of the right upper lung lobe tissues were observed by HE staining. In other lung tissues, the expression of JNK1/2 was detected by Western blotting; ET-2 was tested by Western blotting and immunohistochemistry; thiobarbituric acid reactive substances (TBARS) assay and trace enzyme standard method were used to measure malondialdehyde (MDA) and glutathione (GSH), respectively. Results Compared with normal control group, the number of airway inflammation cells increased in the BALF, and the expressions of ET-2, JNK1/2, MDA and GSH increased in the lung tissues of cigarette smoke control group, asthma model group and cigarette smoke-exposed asthma group. Compared with cigarette smoke-exposed asthma group, the number of airway inflammation cells decreased in the BALF, and the expressions of

Full Text Available Background: Exposure to environmental tobacco smoke (ETS has harmful effects on the pregnancy outcomes similar to those observed in actively smoking pregnant women. The aim of this study was to estimate the sensitivity and specificity of the breath carbon monoxide (BCO analysis in the assessment of smoking status among Saudi pregnant women, including ETS exposure compared to self-reported tobacco smoke exposure. Methods: A cross-sectional design was used during January 2012, 560 pregnant women, irrespective of their gestational age, agreed to undergo BCO testing and completed the data collection sheet for the study. Sensitivity, specificity, positive and negative predictive values were calculated to compare the BCO test with self-reported exposure to ETS. Results: Of the study population 151 (27% women self-reported ETS exposure during the index pregnancy, 409 (73% self-reported non-exposure. Sensitivity of the test was 32.5% (95% CI; 25.2-40.3%, the Specificity was much higher at 69.2% (95% CI; 64.4-73.5%, the positive predictive value was 28% (95% CI, 21.9-35.1%, and the negative predictive value was 73.5% (95% CI; 68.9-77.7%. Conclusion: The BCO test is an ineffective tool to detect the level of ETS exposure among Saudi pregnant women.

The Relationship between Environmental Tobacco Smoke Exposure and Cardiovascular Disease and the Potential Modifying Effect of Diet in a Prospective Cohort among American Indians: The Strong Heart Study

Directory of Open Access Journals (Sweden)

Sarah Rajkumar

2017-05-01

Full Text Available American Indians experience high rates of cardiovascular diseases (CVD. Environmental tobacco smoke (ETS has been linked to CVD, possibly due to pro-inflammatory and oxidative stress pathways. We examined the relationship between self-reported exposure to ETS and fatal and nonfatal CVD incidence using Cox proportional hazards models among 1843 non-smoking American Indians participating in the Strong Heart Study. We also evaluated potential modifying effects of several dietary nutrients high in anti-inflammatory and anti-oxidant properties with ETS exposure on fatal and nonfatal CVD by creating interaction terms between ETS exposure and the dietary variable. Participants exposed to ETS had a higher hazard (hazard ratio: 1.22; 95% confidence interval, 1.03 to 1.44 for developing CVD compared to persons not exposed. Interaction analyses suggested stronger effects of ETS on CVD incidence among those consuming diets lower in vitamin E as compared to those consuming higher amounts, particularly on the additive scale. Additional research is recommended to clarify whether public health prevention strategies should simultaneously target reductions in ETS exposures and improvements in diets that may exceed the expected benefits of targeting these risk factors separately.

2011-05-01

Full Text Available Abstract Background Despite the need for a reduction in levels of childhood exposure to environmental tobacco smoke (ETS being a recognised public health goal, the delivery of ETS preventive care in child health service settings remains a largely unstudied area. The purpose of this study was to determine the prevalence of ETS preventive care in child health services; differences in the provision of care by type of service; the prevalence of strategies to support such care; and the association between care support strategies and care provision. Method One-hundred and fifty-one (83% child health service managers within New South Wales, Australia completed a questionnaire in 2002 regarding the: assessment of parental smoking and child ETS exposure; the provision of parental smoking cessation and ETS-exposure reduction advice; and strategies used to support the provision of such care. Child health services were categorised based on their size and case-mix, and a chi-square analysis was performed to compare the prevalence of ETS risk assessment and ETS prevention advice between service types. Logistic regression analysis was used to examine associations between the existence of care support strategies and the provision of ETS risk assessment and ETS exposure prevention advice. Results A significant proportion of services reported that they did not assess parental smoking status (26%, and reported that they did not assess the ETS exposure (78% of any child. Forty four percent of services reported that they did not provide smoking cessation advice and 20% reported they did not provide ETS exposure prevention advice. Community based child and family health services reported a greater prevalence of ETS preventive care compared to other hospital based units. Less than half of the services reported having strategies to support the provision of ETS preventive care. The existence of such support strategies was associated with greater odds of care provision

The chronic effects of smoking on regional cerebral blood flow (CBF), and on serum lipids and lipoprotein levels in neurologically normal subjects from 25 to 85 years old were studied. CBF was studied by the 133-Xenon inhalation method and gray matter flow was calculated following the method of Obrist et al. A hundred and twentyfive subjects who had no abnormalities in neurological examinations nor in CT scan, were divided into two groups smokers (48) and non-smokers (77). Those who had a smoking index (Number of cigarettes/day) x (years of smoking history)>200 were designated as smokers. The mean smoking index of smokers was 697. sixty-five of the 77 subjects in the non-smoking group had never smoked, and the mean smoking index of non-smokers was 16. Increased reduction of CBF with advancing age was clearly observed. In the male, CBF was significantly lower in smokers than in non-smokers (mean CBF 15% lower in smokers, p<0.001). Compared to non-smokers, CBF in smokers was found to be significantly lower than the expected age matched value. Serum high density lipoprotein cholesterol values in smokers were significantly lower, and total cholesterol levels significantly higher than in non-smokers. We concluded that smoking chronically reduced CBF. Age dependent decrease of CBF was deteriorated by chronic smoking. Then, chronic smoking was suggested to be a risk factor for brain aging. Decrease of CBF in smokers was probably due to advanced atherosclerosis which produces vascular narrowing and raised resistance in cerebral blood vessels. (author)

Patients with schizophrenia continue to have the highest rate of both smoking and heavy nicotine dependence. The interaction between smoking and schizophrenia is complex. There is evidence of the shared genetic background. Recent preclinical and clinical research has further investigated self-medication hypothesis, given that nicotine might alleviate cortical dysfunction. While prior research indicated some favorable effects of smoking on cognitive performance, particulatly on attention/vigilance, recent studies did not confirm those findings. Lower severity of negative symptoms in smokers was not confirmed across studies. Cigarette smoking decreases clozapine and olanzapine concentrations. There is no consistent evidence of favorable effects of nicotine on symptoms in schizophrenia, but the evidence of detrimental effects of smoking on general health is highly consistent. Smoking cessation should be a priority in patients with schizophrenia.

To use a novel social epidemic probability model to investigate longitudinally the extent to which parents' and older siblings' smoking predict children's smoking transitions. Parents' and older siblings' smoking status was assessed when children were in 3rd grade (baseline). Three smoking transitions were assessed over the period of child/adolescent smoking acquisition (up to 12th grade): (1) transition from never smoking to trying smoking, (2) transition from trying to monthly smoking and (3) transition from monthly to daily smoking. Forty Washington State school districts participating in the long term Hutchinson Smoking Prevention Project (HSPP). Participants were the 5520 families for whom data on both parents' and older siblings' baseline smoking status, as well as on children's smoking transitions, were available. The probability that a smoking parent influenced their child to make the first transition to trying smoking was 32% (95% CI: 27%, 36%); to make the second transition from trying to monthly smoking, 15% (95% CI: 10%, 19%); and to make the third transition from monthly to daily smoking, 28% (95% CI: 21%, 34%). The probability that an older sibling influenced a child to make the first transition to trying smoking was 29% (95% CI: 17%, 39%); to make the second transition from trying to monthly smoking, 0% (95% CI: 0%, 8%); and to make the third transition from monthly to daily smoking, 20% (95% CI: 4%, 33%). In contrast to previous research, the results provide new evidence suggesting that family smoking influences both initiation and escalation of children's smoking. Results also quantify, in terms of probabilities, the importance of parents' and older siblings' smoking on children's three major smoking transitions. Parents' smoking, as well as older siblings' smoking, are important behaviors to target in preventing adolescents from making smoking transitions.

To explore the metamotivational states experienced during first smoking experiences of Asian American adolescents. This survey research investigated the differences among the smokers, resisters, and smoking naives of a convenience sample of 328 Asian Americans, aged 16-19 in New York City (NYC). The study used a demographic questionnaire, Temptation Episode Surveys (First Smoking Occasion, First Resisted Smoking Opportunity, and Opinions on First Smoking Occasion), the Telic/Paratelic State Instrument, and the Rebellious State Scale. Statistical analyses revealed that Asian American adolescents smoked the first time when in paratelic, arousal-seeking states, and when the physical and social environments are permissive to smoking, initiation opportunities such as presence of peers and friends smoking and in places where adults are not present. The first smoking experiences of Asian American adolescents parallel that of smoking cessation when individuals lapse in a highly tempting situation and when the environment is permissive to smoking. This study is the first to use reversal theory pairs as a framework for smoking initiation. Smoking prevention and intervention programs should consider the importance of the physical, social environment, and the psychological states of adolescents when they smoke the first time. © 2012 Wiley Periodicals, Inc.

Exposure to cigarette smoking during foetal and early postnatal life may have implications for lung health. The aim of this study was to assess the possible effects of such exposure in utero on lower respiratory disease in children up to two years of age. A birth cohort of 4089 newborn infants was followed for two years using parental questionnaires. When the infant was two months old the parents completed a questionnaire on various lifestyle factors, including maternal smoking during pregnancy and after birth. At one and two years of age information was obtained by questionnaire on symptoms of allergic and respiratory diseases as well as on environmental exposures, particularly exposure to environmental tobacco smoke (ETS). Adjustments were made for potential confounders. When the mother had smoked during pregnancy but not after that, there was an increased risk of recurrent wheezing up to two years' age, ORadj = 2.2, (95% CI 1.3-3.6). The corresponding OR was 1.6, (95% CI 1.2-2.3) for reported exposure to ETS with or without maternal smoking in utero. Maternal smoking during pregnancy but no exposure to ETS also increased the risk of doctor's diagnosed asthma up to two years of age, ORadj = 2.1, (95% CI 1.2-3.7). Exposure to maternal cigarette smoking in utero is a risk factor for recurrent wheezing, as well as doctor's diagnosed asthma in children up to two years of age.

In a part of building ventilating installation of reprocessing plant, the pre-filter is equipped in front of a HEPA filter. The pre-filter plays a role in protection and repression of clogging of HEPA filter. However, in a fire accident, it is considered that large smoke generation cause the pre-filter clogging due to smoke loading, increase of differential pressure and breakdown. In Japan Atomic Energy Research Institute, the demonstration tests to confirm the performance of ventilation filters by a fire accident were carried out. In the tests, smoke was generated from burning of the mock solid wastes (gloves made of rubber and/or cloth) or the mock recovered solvent (n-dodecane or tributyl phosphate / n-dodecane). The test data was acquired on generation of smoke, decrease evolution of smoke by transportation through the compositions of ventilation system (cell, duct, damper, filters) and clogging characteristics of the ventilation filters due to smoke loading. From the results, it was found that the performance of the whole of ventilation system was kept even if the pre-filter was breakdown. To adopt the analysis of the increase of differential pressure across the pre-filter using the safety analysis code, CELVA-1D, increase of differential pressure across the pre-filter was expressed by quadratic empirical equation with function of smoke loading per unit filtration area and it coefficients, ({alpha}, {beta}), were estimated.

Smoking cessation is challenging and lack of positive support is a known major barrier to quitting cigarettes. Previous studies have suggested that social influences might increase smokers' awareness of social norms for appropriate behavior, which might lead to smoking cessation. Although social media use is increasing among young adults in the United States, research on the relationship between social media use and smoking cessation is lacking. Twitter has provided a rich source of information for researchers, but no overview exists as to how the field uses Twitter in smoking cessation research. To the best of our knowledge, this study conducted a data mining analysis of Twitter to assess barriers to smoking cessation. In conclusion, Twitter is a cost-effective tool with the potential to disseminate information on the benefits of smoking cessation and updated research to the Twitter community on a global scale.

Matthew C Farrelly

Full Text Available OBJECTIVES: To isolate the independent influence of exposure to smoking and other adult content in the movies on youth smoking uptake. METHODS: We used discrete time survival analysis to quantify the influence of exposure to smoking and other adult content in the movies on transitioning from (1 closed to open to smoking; (2 never to ever trying smoking; and (3 never to ever hitting, slapping, or shoving someone on two or more occasions in the past 30 days. The latter is a comparative outcome, hypothesized to have no correlation with exposure to smoking in the movies. RESULTS: Assessed separately, both exposure to smoking imagery and exposure to adult content were associated with increased likelihood of youth becoming open to smoking (OR = 1.09, 95% CI: 1.04-1.15 and OR = 1.10, 95% CI: 1.04-1.17 and having tried smoking (OR = 1.06, 95% CI: 1.00-1.12 and OR = 1.06, 95% CI: 1.00-1.13. Both measures were also separately associated with aggressive behavior (OR = 1.09, 95% CI: 1.04-1.14 and OR = 1.09, 95% CI: 1.04-1.15. A very high correlation between the two measures (0.995, p<0.000 prevented an assessment of their independent effects on smoking initiation. CONCLUSION: Although exposure to smoking in the movies is correlated with smoking susceptibility and initiation, the high correlation between exposure to smoking in the movies and other adult content suggests that more research is needed to disentangle their independent influence on smoking.

Factors associated with parental smoking in the presence of school-aged children: a cross-sectional study

Science.gov (United States)

2013-01-01

Background In 2009, the Tobacco Hazards Prevention Act (Taiwan) was amended to more effectively restrict smoking in indoor public places and workplaces in Taiwan. However, the lack of prohibitions for smoking in private homes may place family members at increased risk for exposure to environmental tobacco smoke (ETS). The aim of our study was to determine the factors associated with parental smoking in the presence of children at home. Methods In 2010, we performed a cross-sectional study of factors associated with parental smoking in the presence of children at home in Taiwan using self-administered questionnaires. Quota sampling was used to select five primary schools from four different regions of Taiwan. Parents were surveyed to identify parental smokers and 307 parental smokers were selected for participation in our study. Questionnaire data regarding parental smoking in the presence of children at home and related interactions among family members were analyzed. Hierarchical logistic regression was used to determine the best-fit model for examining the relationships among the variables related to parental smoking in the presence of children at home. Results Two-thirds of parents who smoked reported smoking in the presence of their children. The results of the hierarchical logistic regression analysis identified the smokers’ compliance with their family’s antismoking responses, mutual agreement with smoking bans, daily smoking, smoking more than 20 cigarettes per day, the education level of the parental smoker, and the annual family income as determinants of smoking in the presence of children at home. Conclusions Households with smoking parents should be targeted for interventions to encourage the adoption and enforcement of home smoking bans. Educational interventions that promote smoke-free homes for children and provide support to help parents stop smoking are critical factors in reducing the frequency of children’s ETS exposure in the home.

Risk reduction: perioperative smoking intervention

DEFF Research Database (Denmark)

Møller, Ann; Tønnesen, Hanne

2006-01-01

Smoking is a well-known risk factor for perioperative complications. Smokers experience an increased incidence of respiratory complications during anaesthesia and an increased risk of postoperative cardiopulmonary complications, infections and impaired wound healing. Smokers have a greater risk...... of postoperative intensive care admission. Even passive smoking is associated with increased risk at operation. Preoperative smoking intervention 6-8 weeks before surgery can reduce the complications risk significantly. Four weeks of abstinence from smoking seems to improve wound healing. An intensive, individual...... approach to smoking intervention results in a significantly better postoperative outcome. Future research should focus upon the effect of a shorter period of preoperative smoking cessation. All smokers admitted for surgery should be informed of the increased risk, recommended preoperative smoking cessation...

There are International and National standards that requires hospitals and health premises to be smoke-free. According to recent data from Italy and other European Countries, smoking is a widespread habit in hospitals. To get smoke-free hospitals in an Italian region, we have adopted the European Code for smoke-free hospitals, which sets standards and provides instruments for its implementation. According to the Code, whenever possible, each step towards a smoke-free hospital, should be shared by all staff. As a mean for achieving this goal, in our region the certification of single units as smoke-free units has been chosen. For getting the certification, besides implementing the Code, we planned to use ETS (Environmental Tobacco Smoke) monitoring, as ETS should not be present in hospitals. As a marker of ETS we have chosen Particulate Matter (PM), as it can easily be measured in real-time with a portable instrument and, when other even outdoor--sources of combustion can be ruled out, it is an accurate detector of cigarette smoke. Here the first experience of measuring PM in hospitals for monitoring ETS and certificating smoke-free health premises, is described. PM measurements were carried out without any previous notification in different areas of two Network hospitals of the Veneto Region, during a single working day. A real time laser-operated aerosol mass analyser was used. Several classes of PM (PM1, PM2.5, PM7, PM10, TSP Total Suspended Particles) were measured. Outdoor PM levels were found to be repeatedly lower than the annual official limits of 65 mcg/m3 and around the 24 hour official limits of 15 mcg/m3 [15 to 20 mcg/m3, with an overall mean (+/-SD) of 17.8 (1.9)] throughout the whole day. Very good indoor air quality was found in the operating theaters and isolation department, where PM2.5 concentrations were much lower than outdoor levels [1.6 (0.9) and 5.9 (0.6) mcg/m3, respectively]. No increase in PM pollution was found in the surveyed medical

The objectives of this research were to evaluate whether there was an association between seeing an actor smoke in telenovelas, Brazilian films, or international films, and trying to quit and quitting among adult Brazilian smokers. Data from 39,425 participants in the Global Adult Tobacco Survey were used. Quit ratio (former smoker/former smoker + ever smoker) and proportions of current, former, and never smokers were calculated. Multivariable weighted regression was used to determine significant associations between quitting smoking and exposure to telenovelas and films. For current smokers, the odds of trying to quit were significantly higher among those who saw an actor smoking in a Brazilian film. Those who believed smoking caused serious illness and had rules in the home prohibiting smoking were significantly more likely to have tried to quit or had quit smoking. Exposure to smoking in the media may be different in adults than adolescents. Influential factors for trying to quit and quitting are rules prohibiting smoking at home, belief that smoking causes serious illness, and hearing about dangers of smoking in media.

"Conclusions about exposure to ETS and health that will be unhelpful to us": how the tobacco industry attempted to delay and discredit the 1997 Australian National Health and Medical Research Council report on passive smoking.

Science.gov (United States)

Trotter, L; Chapman, S

2003-12-01

Major reviews of the health effects of passive smoking have been subjected to tobacco industry campaigns to refute the scientific evidence. Following the 1992 US Environmental Protection Agency review, the Australian National Health and Medical Research Council (NHMRC) initiated a review of the health effects of passive smoking. At the time of this review, evidence that environmental tobacco smoke causes disease was being increasingly accepted in courts of law and voluntary adoption of smoking restrictions was rapidly growing. To demonstrate how the tobacco industry attempted to delay and discredit the publication of a report on passive smoking that the tobacco industry anticipated to contain recommendations that would be unfavourable to their business. A search of tobacco industry documents on the Master Settlement Agreement websites was conducted using the terms and acronyms representative of the NHMRC review. The tobacco industry sought to impede the progress of the NHMRC Working Party by launching an intensive campaign to delay and discredit the report. The main strategies used were attempts to criticise the science, extensive use of Freedom of Information provisions to monitor all activity of the group, legal challenges, ad hominem attacks on the credibility of the Working Party members, rallying support from industry allies, and influencing public opinion through the media. The Australian tobacco industry deliberately impeded the NHMRC Working Party's progress and successfully prevented the publication of the report's recommendations. The tobacco industry's motivation and capacity to disrupt the advancement of scientific knowledge and policy in tobacco control should be recognised and anticipated.

Smoking and Pulmonary Fibrosis: Novel Insights

Full Text Available The relationship between smoking and pulmonary fibrosis is under debate and intense investigation. The aim of this paper is to review the existing literature and identify further areas of research interest. Recently the negative influence of cigarette smoking on IPF outcome was highlighted, as non-smokers exhibit a better survival than ex-smokers and combined current- and ex-smokers. In patients with non-specific interstitial pneumonia (NSIP, a high prevalence of emphysema was recently demonstrated, providing an indirect support for a smoking pathogenetic hypothesis in NSIP. The coexistence of pulmonary fibrosis and emphysema has been extensively described in a syndrome termed combined pulmonary fibrosis and emphysema (CPFE. Connective tissue disorders (CTDs are a group of autoimmune diseases which affect the lung, as one of the most common and severe manifestations. However, the relationship between smoking and autoimmune disorders is still conflicting. Rheumatoid arthritis results from the interaction between genetic and environmental factors, while the best established environmental factor is tobacco smoking. Smoking has also a negative impact on the response of the RA patients to treatment. The aforementioned smoking-related implications give rise to further research questions and certainly provide one more important reason for physicians to advocate smoking cessation and smoke-free environment.

Despite the fact that nurses have a key role in health promotion, many continue to smoke at much the same rate as the general population. This paper investigates the influence of smoking status, gender, age, stage of education, and smoking duration on undergraduate nursing students' attitudes towards smoking health promotion. The study took place in one university's School of Nursing in Victoria, Australia. Respondents completed the Smoking and Health Promotion instrument. Researchers obtained ethics approval prior to commencing the study. Smoking status was the main factor that affected respondents' attitudes towards smoking health promotion, with age and education stage having a minor effect, and gender and smoking duration not significant. Nurses have an important role in modeling non-smoking behaviors for patients. There needs to be consistency between personal and professional beliefs for nurses to properly engage in smoking health promotion. The findings have implications for undergraduate nursing education curricula, nursing practice and research, and these are discussed.

In Taiwan, the Smoke-Free Restaurant Program (SFRP) was implemented from 2003 to 2005 as an initial phase before the introduction of restrictive legislation promoting smoke-free restaurants (SFRs). No studies have evaluated trends in public opinion before and after a national health promotion campaign for the introduction of SFRs on a voluntary basis. The present study investigated whether public opinion with respect to eliminating environmental tobacco smoke (ETS) in restaurants changed after implementation of the SFRP. Data were obtained from four large-scale, nationally representative surveys conducted in 2003-2005 before and after implementation of the SFRP. Weighted analyses were performed to obtain nationally representative results. After a series of SFRP campaigns, reported exposure to ETS in restaurants by survey participants decreased by approximately 14%. Approximately 20% more people had heard of SFRs, and approximately 25% more had chosen to dine in a smoke-free restaurant. We found consistently high community support for SFRs (ca. 95%), and approximately 80% supported smoke-free restaurant legislation, although both rates dropped slightly in 2005. People aged 60 years or more, nonsmokers, and those who had greater knowledge of ETS hazards were more likely to support smoke-free restaurant legislation. The SFRP was effective at promoting SFRs on a voluntary basis. Strong community endorsement has major implications for legislators who are considering the nature and extent of further smoke-free restaurant legislation in Taiwan and other countries.

Full Text Available Objective: To review the literature on associations between cardiovascular diseases and tobacco use, including recent trends in smoking behaviors and clinical approaches for cessation of smoking. Methods: A literature review of recent scientific findings for smoking and cardiovascular diseases and recommendations for obtaining cessation. Results: Tobacco smoking is causally related to cardiovascular disease, with nearly a half million deaths annually attributed to cigarette smoking in the United States. The human, economic, medical, and indirect costs are enormous. Secondhand smoke as inhaled from the environment also plays an important role in the genesis of cardiovascular diseases. A recent trend in the use of e-cigarettes is noted particularly among youth. For children, prevention is the best strategy. For adult smokers, behavioral treatments, self-help approaches, and pharmacologic therapies are readily available. Clinicians can have a significant impact on patients’ smoking habits. Adding to individual strategies, regulatory community and public health approaches provide the potential for eliminating the use of tobacco. Conclusion: Tobacco smoke causes cardiovascular morbidity and death. Clinicians can play a role in preventing smoking and promoting cessation.

Women and smoking.

Smoking kills over half a million women each year and is the most important preventable cause of female premature death in several developed countries. However, in many countries, cigarette smoking still tends to be regarded as a mainly male problem. This paper explores the reasons why more attention needs to be paid to issues around smoking and women, even in countries which currently have low levels of female cigarette smoking. The article includes an overview of current patterns and trends of smoking among women, and the factors which influence smoking uptake and cessation in women compared to men. The experience of countries with the longest history of widespread female smoking is used to identify some of the key challenges facing developed and developing countries. Tobacco companies have identified women as a key target group, therefore particular attention is given to the ways in which they have attempted to reach women through advertising and other marketing strategies. It is concluded that in order to halt and ultimately reverse the tobacco epidemic among women, tobacco control policies need to encompass both gender-specific and gender-sensitive approaches. Examples are given of the types of action that are needed in relation to research, public policy and legislation, and education.

Smoking bans have been implemented in a variety of settings, as well as being part of policy in many jurisdictions to protect the public and employees from the harmful effects of secondhand smoke (SHS). They also offer the potential to influence social norms and the smoking behaviour of those populations they affect. Since the first version of this review in 2010, more countries have introduced national smoking legislation banning indoor smoking. To assess the effects of legislative smoking bans on (1) morbidity and mortality from exposure to secondhand smoke, and (2) smoking prevalence and tobacco consumption. We searched the Cochrane Tobacco Addiction Group Specialised Register, MEDLINE, EMBASE, PsycINFO, CINAHL and reference lists of included studies. We also checked websites of various organisations. Date of most recent search; February 2015. We considered studies that reported legislative smoking bans affecting populations. The minimum standard was having an indoor smoking ban explicitly in the study and a minimum of six months follow-up for measures of smoking behaviour. Our search included a broad range of research designs including: randomized controlled trials, quasi-experimental studies (i.e. non-randomized controlled studies), controlled before-and-after studies, interrupted time series as defined by the Cochrane Effective Practice and Organisation of Care Group, and uncontrolled pre- and post-ban data. One author extracted characteristics and content of the interventions, participants, outcomes and methods of the included studies and a second author checked the details. We extracted health and smoking behaviour outcomes. We did not attempt a meta-analysis due to the heterogeneity in design and content of the studies included. We evaluated the studies using qualitative narrative synthesis. There are 77 studies included in this updated review. We retained 12 studies from the original review and identified 65 new studies.

Background: Exposure to smoke, including environmental tobacco smoke (ETS), is a well-known risk factor for diabetes. Low socioeconomic status, especially lack of education, is also a risk factor for diabetes. Therefore, we assessed the association of demographic, socioeconomic, clinical, and behavior risk factor-related variables and smoking status, including ETS exposure, with the prevalence of diabetes. Methods: Data were from the 2007-2013 Korea National Health and Nutritional Evaluation Survey (KNHANES). Multivariable logistic regression examined associations between various lifestyle and health factors and the prevalence of diabetes while controlling for potential confounding variables. Subgroup analysis was performed according to smoking status to determine factors associated with diabetes. Results: Of 19,303 individuals analyzed, 1325 (11.4%) had diabetes. Greater average age, male sex, lower educational level, unemployment, and coexisting health problems were significantly associated with diabetes. Individuals with only elementary, middle, or high school level education had significantly greater odds ratios ( p education, urban residence, National Health Insurance (NHI), hypertension, a lack of alcohol intake, and a lack of moderate physical activity. For diabetic smokers, there were significant associations ( p education, urban residence, a lack of moderate physical activity, a lack of alcohol intake, and NHI. Conclusions: The results suggested that smoking status, as well as ETS exposure, was associated with a higher prevalence of diabetes, especially in populations with less education. Thus, we should direct efforts for controlling diabetes toward individuals with lower levels of education and those who are smokers and nonsmokers exposed to ETS.

Smoke-free legislation has been a great success for tobacco control but its impact on smoking uptake remains under-explored. We investigated if trends in smoking uptake amongst adolescents differed before and after the introduction of smoke-free legislation in the United Kingdom. Prevalence estimates for regular smoking were obtained from representative school-based surveys for the four countries of the United Kingdom. Post-intervention status was represented using a dummy variable and to allow for a change in trend, the number of years since implementation was included. To estimate the association between smoke-free legislation and adolescent smoking, the percentage of regular smokers was modeled using linear regression adjusted for trends over time and country. All models were stratified by age (13 and 15 years) and sex. For 15-year-old girls, the implementation of smoke-free legislation in the United Kingdom was associated with a 4.3% reduction in the prevalence of regular smoking (P = .029). In addition, regular smoking fell by an additional 1.5% per annum post-legislation in this group (P = .005). Among 13-year-old girls, there was a reduction of 2.8% in regular smoking (P = .051), with no evidence of a change in trend post-legislation. Smaller and nonsignificant reductions in regular smoking were observed for 15- and 13-year-old boys (P = .175 and P = .113, respectively). Smoke-free legislation may help reduce smoking uptake amongst teenagers, with stronger evidence for an association seen in females. Further research that analyses longitudinal data across more countries is required. Previous research has established that smoke-free legislation has led to many improvements in population health, including reductions in heart attack, stroke, and asthma. However, the impacts of smoke-free legislation on the rates of smoking amongst children have been less investigated.

Molecular studies have demonstrated actionable driver oncogene alterations are more frequent in never-smokers with non-small-cell lung cancer (NSCLC). The etiology of these driver oncogenes in patients with NSCLC remains unknown, and environmental tobacco smoke (ETS) is a potential cause in these cases. We assembled clinical and genetic information for never-smoker patients with NSCLC accrued in Japan, Korea, Singapore, and the United States. To determine an association between cumulative ETS and activating EGFR mutations or ALK rearrangements, the Mantel extension test was used. Multivariate analysis on activating EGFR and ALK gene rearrangements was performed using the generalized linear mixed model with nations as a random effect. From July 2007 to December 2012, 498 never-smokers with pathologically proven NSCLC were registered and tested for the association between ETS and EGFR and ALK status. EGFR mutations were more frequent in the ever-ETS cohort (58.4%) compared with the never-ETS cohort (39.6%), and the incidence of EGFR mutations was significantly associated with the increment of cumulative ETS (cETS) in female never-smokers (P = .033), whereas the incidence of ALK rearrangements was not significantly different between the ever-ETS and never-ETS cohorts. Odds ratio for EGFR mutations for each 10-year increment in cETS was 1.091 and 0.89 for female and male never-smokers (P = .031 and P = .263, respectively). Increased ETS exposure was closely associated with EGFR mutations in female never-smokers with NSCLC in the expanded multinational cohort. However, the association of ETS and ALK rearrangements in never-smokers with NSCLC was not significant. Copyright © 2017 Elsevier Inc. All rights reserved.

Should we bother with second-hand smoke exposure if smoking is on track?

DEFF Research Database (Denmark)

Adám, Balázs

2014-01-01

The recognition of the serious health-damaging effects of tobacco smoke exposure has initiated several preventive programmes on the national and international levels worldwide. In the last decade, a considerable decrease in the prevalence of active smoking was observed in Denmark, changing...... the country from a poor to a favourable position in comparison to other EU countries. However, second-hand tobacco smoke exposure, especially in homes, still ranks Denmark among the problematic countries in Europe. This poorly recognised and studied discrepancy calls for further research and effective...

Although research indicates that second-hand smoke (SHS) harms both human and animal health, data on the percentage of pet owners who smoke or allow smoking in their homes are not readily available. To investigate pet owners' smoking behaviour and policies on smoking in their homes, and the potential for educational interventions to motivate change in pet owners' smoking behaviour. A web-based survey was used with 3293 adult pet owners. The main outcome measures were smoking behaviour of pet owners and their cohabitants; policies on smoking in pet owners' homes; and impact of information about the dangers of pet exposure to SHS on pet owners' smoking intentions. Of respondents, 21% were current smokers and 27% of participants lived with at least one smoker. Pet owners who smoke reported that information on the dangers of pet exposure to SHS would motivate them to try to quit smoking (28.4%) and ask the people with whom they live to quit smoking (8.7%) or not to smoke indoors (14.2%). Moreover, non-smoking pet owners who live with smokers said that they would ask the people with whom they live to quit (16.4%) or not smoke indoors (24.2%) if given this information. About 40% of current smokers and 24% of non-smokers living with smokers indicated that they would be interested in receiving information on smoking, quitting, or SHS. Educational campaigns informing pet owners of the risks of SHS exposure for pets could motivate some owners to quit smoking. It could also motivate these owners and non-smoking owners who cohabit with smokers make their homes smoke-free.

Smoking in pregnancy can cause substantial harm and, while many women quit, others continue to smoke throughout pregnancy. The role of partners is an important but relatively under-researched factor in relation to women's smoking in pregnancy; partner's smoking status and attitudes to smoking cessation are important influences in a pregnant women's attempt to quit. Further understanding of how partners perceive the barriers and facilitators to smoking cessation in pregnancy is needed, particularly from qualitative studies where participants describe these issues in their own words. A synthesis of qualitative research of partners' views of smoking in pregnancy and post-partum was conducted using meta-ethnography. Searches were undertaken from 1990 to January 2014 using terms for partner/household, pregnancy, post-partum, smoking, qualitative in seven electronic databases. The review was reported in accordance with the 'Enhancing transparency in reporting the synthesis of qualitative research' (ENTREQ) statement. Nine studies reported in 14 papers were included, detailing the experience of 158 partners; the majority were interviewed during the post-partum period. Partners were all male, with a single exception. Socioeconomic measures indicated that most participants were socially disadvantaged. The synthesis identified recurring smoking-related perceptions and experiences that hindered (barriers) and encouraged (facilitators) partners to consider quitting during the woman's pregnancy and into the post-partum period. These were represented in five lines of argument relating to: smoking being an integral part of everyday life; becoming and being a father; the couple's relationship; perceptions of the risks of smoking; and their harm reduction and quitting strategies. The cluster of identified barriers and facilitators to quitting offers pointers for policy and practice. The workplace emerges as an important space for and influence on partners' smoking habits

Narghile smoking pastes, known as jurak and moassel, are not standardized manufacture. This study aims at drawing the first conclusions on the potential hazards of radioactivity in relation to moassel-narghile smoking. The results indicate the existence of a wide range of variations in the natural radioactivity. The distribution pattern of these natural radio-nuclides, during smoking, between smoke, ash and water filter is unknown, except for 210Po. Radiological dose assessment due to intake of 210Po was calculated and the possible radio-toxicity of the measured radio-nuclides is discussed. Further research in this direction is needed.

To investigate whether parenting style is an independent risk factor of smoking initiation and experimentation among adolescents, and whether there is a relationship between parenting style and readiness to quit, or nicotine dependence among smokers. The 84-item Health and Smoking Questionnaire, which assesses demographics, smoking status and smoking history, perceptions of risk and risk reduction, risk factors for tobacco use, and parenting style, was administered to 816 adolescents in grades 7 to 12 (mean age, 15.1 years) of whom 22.6% (n = 182) were smokers. Parenting style was measured by the brief, non-retrospective version of the Family of Origin Scale (FOS). Higher scores on the FOS indicated more positive perceived parenting style with high levels of intimacy and autonomy, characteristics of healthy parent-child relationships. Data were analyzed using a model-building approach to logistic regression with demographic and other psychosocial variables in the first two steps, and with parenting style as the last step. Results from two logistic regression models indicate that although parenting style is not a significant risk factor for smoking experimentation [odds ratio (OR) =.998; confidence interval (CI) =.977-1.019; p =.820], it is a significant independent risk factor for smoking initiation (OR =.950; CI =.930-.970; p =.000). Smokers who were more ready to quit had higher parenting style scores than those who were not ready to quit, and smokers who had made a serious quit attempt (an indicator of nicotine addiction) had higher parenting style scores than those who had not made a quit attempt. Moreover, nonsmokers who reported they would smoke a cigarette if their best friend offered had significantly lower parenting style scores than those who reported they would not smoke a cigarette. Additional research on parenting style and its impact on adolescent smoking with a more economically and ethnically diverse sample is warranted. If future research confirms

In smoking cessation studies with restrictive criteria (e.g., single-smoker couples), thousands of potential participants might need to be screened to obtain a reasonable sample size. Consideration of recruitment methodology is critical because recruitment methods influence both the success and cost effectiveness of recruitment. Although traditional recruitment methods are often used to recruit participants into smoking cessation research, newer technologies, such as paid Facebook advertising, might offer more cost-effective alternatives for recruitment. The current analysis compares two versions of paid Facebook advertising and a specialized mass mailing method used to recruit single-smoker couples into an intensive three-week study of unaided smoking cessation. The three methods are compared in terms of demographic characteristics, eligibility, and cost-effectiveness. Although Facebook's "Promote Your Page" mechanism achieved the fastest recruitment rate (2.75 couples per month; 498 USD per couple), Facebook's "Send People to Your Website" mechanism was the least expensive and provided the most demographically diverse sample (1.64 couples per month; 181 USD per couple). The specialized mailing method was not productive or cost-effective (0.80 couples per month; 454 USD per couple). Paid Facebook advertising fared better as a recruitment method than a specialized mailing method often used in survey research. Studies that have less restrictive eligibility criteria, that draw from a larger local population, or that recruit for a less intense study might find paid Facebook advertising to be quite feasible.

There is uncertainty in the risk of pancreatic cancer with particular aspects of smoking, such as a dose-response relationship and cumulative amount, in Japanese men and women. Very few studies have addressed the role of passive smoking in pancreatic cancer among Japanese women. We examined the association between active or passive smoking and the risk of death from pancreatic cancer using data from the Japan Collaborative Cohort Study. The cohort participants (46,395 men and 64,190 women) were followed-up for mortality from baseline (1988-1990) through December 31, 2009. Cox proportional hazards regression models were used to estimate relative risks (RR) and 95% confidence intervals (CI). During follow-up, we recorded 611 pancreatic cancer deaths. After adjustment for potential confounding factors, current smokers had a significantly increased risk of death from pancreatic cancer compared with non-smokers, with an RR of 1.70 (95% CI: 1.33-2.19). The risk of death from pancreatic cancer significantly increased with increasing numbers of cigarettes smoked per day. Exposure to environmental tobacco smoke (ETS) in public spaces was not associated with risk of death from pancreatic cancer. The RR for women who reported ETS exposure was 1.20 (95% CI: 0.87-1.67). Women exposed to ETS during childhood or adolescence had 1.21-fold increased risk, but the association was statistically insignificant. Cigarette smoking is associated with an approximately 70% increase in the risk of death from pancreatic cancer. Further studies with improved exposure assessment are needed to better quantify the association between passive smoking and pancreatic cancer. Copyright © 2013 IAP and EPC. Published by Elsevier B.V.

Full Text Available Abstract Background To curb the tobacco epidemic a combination of comprehensive interventions are needed at different levels. Smoking uptake is a multi-factorial process that includes societal factors as well as social and individual characteristics. An understanding of the process is essential in order to model interventions. The aim of this study was to explore the role of smoking for young smokers by focusing on the mechanisms that facilitate young people starting to smoke as well as what could have prevented them from starting. Methods A qualitative research design using focus group discussions was chosen as the basis for a content analysis approach. Eight focus groups were conducted with five to six participants in each (four groups with boys, four with girls. The informants were purposively selected to represent smokers in the age range of 15-16 years within the county. The total number of group participants was 44; 21 were girls and 23 boys. The study was performed at 7-9th grade schools in Västerbotten County in northern Sweden. Results Three themes related to different aspects of youth smoking behaviour emerged from the analysis. Theme 1 "gaining control" reflects what makes young people become smokers; theme 2 "becoming a part of the self" focuses on what facilitates youths to start smoking; theme 3 "concerned adults make a difference" indicates what may prevent them from starting. Conclusion Young smokers described starting to smoke as a means of gaining control of feelings and situations during early adolescence. Smoking adolescents expect adults to intervene against smoking. Close relations with concerned adults could be a reason for less frequent smoking or trying to quit smoking. Interventions aimed at normative changes, with consistent messages from both schools and parents about the negative aspects of tobacco seem to be a feasible approach for preventing youth from using tobacco.

Assessing the role of impulsivity in smoking & non-smoking disordered gamblers.

Co-morbidity with other addictive behaviors is common in disordered gambling (DG). In particular, tobacco dependence has been found to be among the most prevalent disorders co-morbid with DG. While the extant literature has firmly established the co-occurrence of DG and smoking, there is a paucity of research examining factors that differentiate DGs who smoke from those who do not. To address this empirical gap, the current study tested whether dimensions of trait impulsivity as measured by the UPPS-P Impulsive Behavior Scale (positive urgency, negative urgency, lack of premeditation, lack of perseverance, and sensation seeking), discriminated between non-DGs and DGs based on their present smoking status: non-smoker, occasional smoker, and daily smoker. To this end, 564 community gamblers were recruited through a crowdsourcing platform (Amazon's Mechanical Turk) and completed an online survey, assessing problem gambling severity, tobacco use, and trait impulsivity. MANOVA analyses revealed significant main effects for both gambling severity and smoking status groups. Importantly, a significant gambling by smoking interaction was also found. Pairwise comparisons revealed that DGs who were daily smokers scored higher on negative urgency than those who smoked occasionally or not all. Furthermore, among non-DGs, smoking status failed to discriminate between mean scores on negative urgency. No other significant interaction effects were found for the remaining UPPS-P impulsivity facets. Results suggest that individual components of trait impulsivity, and more specifically negative urgency, successfully differentiate DGs who do not smoke, or just smoke occasionally, from DGs who smoke daily. These findings suggest that the degree of trait impulsivity may potentially distinguish between DGs and DGs who are dually addicted to other substances such as tobacco. Copyright © 2017 Elsevier Ltd.

Huang, Jidong; Zheng, Rong; Emery, Sherry

2013-01-01

Background Despite the tremendous economic and health costs imposed on China by tobacco use, China lacks a proactive and systematic tobacco control surveillance and evaluation system, hampering research progress on tobacco-focused surveillance and evaluation studies. Methods This paper uses online search query analyses to investigate changes in online search behavior among Chinese Internet users in response to the adoption of the national indoor public place smoking ban. Baidu Index and Google Trends were used to examine the volume of search queries containing three key search terms “Smoking Ban(s),” “Quit Smoking,” and “Electronic Cigarette(s),” along with the news coverage on the smoking ban, for the period 2009–2011. Findings Our results show that the announcement and adoption of the indoor public place smoking ban in China generated significant increases in news coverage on smoking bans. There was a strong positive correlation between the media coverage of smoking bans and the volume of “Smoking Ban(s)” and “Quit Smoking” related search queries. The volume of search queries related to “Electronic Cigarette(s)” was also correlated with the smoking ban news coverage. Interpretation To the extent it altered smoking-related online searches, our analyses suggest that the smoking ban had a significant effect, at least in the short run, on Chinese Internet users’ smoking-related behaviors. This research introduces a novel analytic tool, which could serve as an alternative tobacco control evaluation and behavior surveillance tool in the absence of timely or comprehensive population surveillance system. This research also highlights the importance of a comprehensive approach to tobacco control in China. PMID:23776504

Electronic cigarettes (e-cigarettes) are promoted as smoking cessation tools, yet they remain unavailable from Stop Smoking Services in England; the debate over their safety and efficacy is ongoing. This study was designed to explore perceptions and reasons for use or non-use of electronic cigarettes as smoking cessation tools, among individuals engaged in Stop Smoking Services. Semi-structured telephone interviews were undertaken with twenty participants engaged in Stop Smoking Services in the north-west of England. Participants comprised of both individuals who had tried e-cigarettes (n = 6) and those who had not (n = 14). Interviews were digitally recorded and transcribed verbatim. The transcripts were subject to thematic analysis, which explored participants' beliefs and experiences of e-cigarettes. A thematic analysis of transcripts suggested that the following three superordinate themes were prominent: (1) self-efficacy and beliefs in e-cigarettes; (2) e-cigarettes as a smoking cessation aid; and (3) cues for e-cigarette use. Participants, particularly never users, were especially concerned regarding e-cigarette efficacy and safety. Overall, participants largely expressed uncertainty regarding e-cigarette safety and efficacy, with some evidence of misunderstanding. Evidence of uncertainty and misunderstanding regarding information on e-cigarettes highlights the importance of providing smokers with concise, up-to-date information regarding e-cigarettes, enabling smokers to make informed treatment decisions. Furthermore, identification of potential predictors of e-cigarette use can be used to inform Stop Smoking Services provision and future research. What is already known on this subject? Research suggests that e-cigarettes may help smokers quit smoking, but further studies are needed. Electronic cigarette use in Stop Smoking Services has increased substantially in recent years, although e-cigarettes are currently not regulated. There is debate within the

A man before his time: Russell's insights into nicotine, smoking, treatment and curbing the smoking problem.

This narrative review aimed to provide a brief overview of five key research 'classics' produced by the innovative and radical thought leader, Professor Michael Anthony Hamilton Russell (1932-2009), drawing upon his other work wherever feasible. Narrative review. From more than 250 publications, we selected papers we considered seminal texts, published in 1971, 1976, 1978, 1979 and 1991. Russell was among the first researchers to explain that smoking was a dependence disorder caused by the drug nicotine decades before this was recognized formally. He therefore saw quickly the importance of delivering nicotine in a less harmful format as a way of controlling nicotine withdrawal when stopping smoking, first studying nicotine gum. In addition to pharmacotherapies, Russell's research also explored the role of behavioural support, particularly the role of general practitioners (GPs), alone as well as supported by specialist clinics; this research underpinned initiatives in England to reimburse doctors for giving advice to smokers, and to provide a national network of smoking cessation services. Research on nicotine uptake from other delivery systems and routes led Russell to theorize that the speed and dose of delivery impacted upon the effectiveness of a product to act as a substitute for smoking. He commented on the addictiveness of the high nicotine boli delivered in quick succession when smoking cigarettes and argued that alternative recreational nicotine delivery systems would need to be promoted actively to smokers in order for them to compete with cigarettes, a forerunner for contemporary debates on electronic cigarettes. The legacy of Russell's landmark research is seen in present-day nicotine science, policy and discourse. © 2017 Society for the Study of Addiction.

Although nicotine replacement and other pharmacological treatments head the list of popular interventions for smoking cessation, approaches based on psychology can also assist smokers. Hypnosis, suggestion, and behavior therapies have been offered to patients and studied experimentally for several decades. Although no single psychological approach has been found to be superior to others, psychological interventions contribute significantly to successful treatment outcome in smoking cessation. This article describes common hypnotic and behavioral approaches to smoking cessation and critically reviews some of the findings from clinical and experimental research studies. The authors also offer suggestions regarding treatment and future research.

Cigarette smoke chemistry market maps under Massachusetts Department of Public Health smoking conditions.

This study extends the market mapping concept introduced by Counts et al. (Counts, M.E., Hsu, F.S., Tewes, F.J., 2006. Development of a commercial cigarette "market map" comparison methodology for evaluating new or non-conventional cigarettes. Regul. Toxicol. Pharmacol. 46, 225-242) to include both temporal cigarette and testing variation and also machine smoking with more intense puffing parameters, as defined by the Massachusetts Department of Public Health (MDPH). The study was conducted over a two year period and involved a total of 23 different commercial cigarette brands from the U.S. marketplace. Market mapping prediction intervals were developed for 40 mainstream cigarette smoke constituents and the potential utility of the market map as a comparison tool for new brands was demonstrated. The over-time character of the data allowed for the variance structure of the smoke constituents to be more completely characterized than is possible with one-time sample data. The variance was partitioned among brand-to-brand differences, temporal differences, and the remaining residual variation using a mixed random and fixed effects model. It was shown that a conventional weighted least squares model typically gave similar prediction intervals to those of the more complicated mixed model. For most constituents there was less difference in the prediction intervals calculated from over-time samples and those calculated from one-time samples than had been anticipated. One-time sample maps may be adequate for many purposes if the user is aware of their limitations. Cigarette tobacco fillers were analyzed for nitrate, nicotine, tobacco-specific nitrosamines, ammonia, chlorogenic acid, and reducing sugars. The filler information was used to improve predicting relationships for several of the smoke constituents, and it was concluded that the effects of filler chemistry on smoke chemistry were partial explanations of the observed brand-to-brand variation.

Correspondence regarding "Effect of active smoking on the human bronchial epithelium transcriptome"

Directory of Open Access Journals (Sweden)

Zuyderduyn Scott D

2009-02-01

Full Text Available Abstract Background In the work of Chari et al. entitled "Effect of active smoking on the human bronchial epithelium transcriptome" the authors use SAGE to identify candidate gene expression changes in bronchial brushings from never, former, and current smokers. These gene expression changes are categorized into those that are reversible or irreversible upon smoking cessation. A subset of these identified genes is validated on an independent cohort using RT-PCR. The authors conclude that their results support the notion of gene expression changes in the lungs of smokers which persist even after an individual has quit. Results This correspondence raises questions about the validity of the approach used by the authors to analyze their data. The majority of the reported results suffer deficiencies due to the methods used. The most fundamental of these are explained in detail: biases introduced during data processing, lack of correction for multiple testing, and an incorrect use of clustering for gene discovery. A randomly generated "null" dataset is used to show the consequences of these shortcomings. Conclusion Most of Chari et al.'s findings are consistent with what would be expected by chance alone. Although there is clear evidence of reversible changes in gene expression, the majority of those identified appear to be false positives. However, contrary to the authors' claims, no irreversible changes were identified. There is a broad consensus that genetic change due to smoking persists once an individual has quit smoking; unfortunately, this study lacks sufficient scientific rigour to support or refute this hypothesis or identify any specific candidate genes. The pitfalls of large-scale analysis, as exemplified here, may not be unique to Chari et al.

Parental smoking, exposure to secondhand smoke at home, and smoking initiation among young children.

To investigate the associations of parental smoking and secondhand smoke (SHS) exposure at home with smoking initiation among young children in Hong Kong. A prospective school-based survey of Hong Kong primary 2-4 students was conducted at baseline in 2006 and followed up in 2008. Self-administered anonymous questionnaires were used to collect information about smoking, SHS exposure at home, parental smoking, and sociodemographic characteristics. Cross-sectional and prospective associations of SHS exposure at home and parental smoking with student smoking were analyzed using logistic regression adjusting for potential confounders. Cross-sectional association between parental smoking and ever smoking was significant with adjustment of sociodemographic characteristics but became insignificant after adjusting for home SHS exposure. Home SHS exposure mediated the association between parental smoking and students smoking (p = .03). Prospectively, parental smoking was not associated with smoking initiation after adjusting for home SHS exposure. Each day increase in home SHS exposure significantly predicted 16% excess risk of smoking initiation after adjusting for parental smoking. The prospective effect of parental smoking on smoking initiation was significantly mediated by baseline home SHS exposure (p smoking initiation of young Chinese children in Hong Kong independent of parental smoking status. On the other hand, the effect of parental smoking on smoking initiation was mediated through SHS exposure at home. To prevent children from smoking as well as the harm of SHS exposure, parents and other family members should quit smoking or at least reduce smoking at home.

Peers and adolescent smoking.

Kobus, Kimberly

2003-05-01

There is a considerable body of empirical research that has identified adolescent peer relationships as a primary factor involved in adolescent cigarette smoking. Despite this large research base, many questions remain unanswered about the mechanisms by which peers affect youths' smoking behavior. Understanding these processes of influence is key to the development of prevention and intervention programs designed to address adolescent smoking as a significant public health concern. In this paper, theoretical frameworks and empirical findings are reviewed critically which inform the current state of knowledge regarding peer influences on teenage smoking. Specifically, social learning theory, primary socialization theory, social identity theory and social network theory are discussed. Empirical findings regarding peer influence and selection, as well as multiple reference points in adolescent friendships, including best friendships, romantic relationships, peer groups and social crowds, are also reviewed. Review of this work reveals the contribution that peers have in adolescents' use of tobacco, in some cases promoting use, and in other cases deterring it. This review also suggests that peer influences on smoking are more subtle than commonly thought and need to be examined more carefully, including consideration of larger social contexts, e.g. the family, neighborhood, and media. Recommendations for future investigations are made, as well as suggestions for specific methodological approaches that offer promise for advancing our knowledge of the contribution of peers on adolescent tobacco use.

SUMMARY OBJECTIVE To investigate smoking patterns in an elderly, low-income population and to identify predictors of smoking cessation, in addition to analyzing the importance of smoking in relation to other risk factors for hospitalization. DESIGN The data were part of an urban health study conducted among 740 individuals aged ≥60 years in three suburban communities of low socio-economic status in Beirut, one of them a refugee camp. A detailed interview schedule was administered that included comprehensive social and health information. RESULTS The overall prevalence of current smokers was 28.1%. Almost half of the group were ever smokers, of whom 44% had quit smoking when they experienced negative health effects. Having at least one chronic illness and having a functional disability significantly increased the odds of smoking cessation. In addition, being a former smoker increased the likelihood of hospital admission. CONCLUSIONS This study is of particular importance, as it has implications for similar low-income and refugee communities in the region and elsewhere. There is a need for more concerted efforts by public health officials to target elderly individuals as a group for smoking cessation interventions, particularly now that mortality and health benefits have been well documented. RÉSUMÉ OBJECTIF Investiguer les types de tabagisme dans une population âgée à faibles revenus et identifier les facteurs prédictifs de l’arrêt du tabagisme, tout en analysant l’importance du tabagisme par rapport aux autres facteurs de risque d’hospitalisation.

Two lines of psychological research have attempted to spell out the stages of adolescent smoking initiation. The first has focused on behavioral stages of smoking initiation, while the second line emphasized motivational stages. A large international sample of European adolescents (N = 10,170, mean age = 13.3 years) was followed longitudinally. Self-reported motivational and behavioral stages of smoking initiation were integrated, leading to the development of the Model of Unplanned Smoking Initiation of Children and Adolescents (MUSICA). The MUSICA postulates that youngsters experiment with smoking while they are in an unmotivated state as regards their plans for smoking regularly in the future. More than 95% of the total population resided in one of the seven stages distinguished by MUSICA. The probability of starting to smoke regularly during the 12 months follow-up period increased with advanced stage assignment at baseline. Unique social cognitive predictors of stage progression from the various stages were identified, but effect sizes of predictors of transitions were small. The integration of motivational and behavioral dimensions improves our understanding of the process of smoking initiation. In contrast to current theories of smoking initiation, adolescent uptake of smoking behavior was found to be an unplanned action.

Exposure to Peers who Smoke Moderates the Association between Sports Participation and Cigarette Smoking Behavior among Non-White Adolescents

OpenAIRE

Mays, Darren; Luta, George; Walker, Leslie R.; Tercyak, Kenneth P.

2012-01-01

Adolescent sports participants are less likely to smoke cigarettes, and sports participation may prevent young people from smoking. Research suggests that the relationship between sports participation and smoking may vary by race/ethnicity and is also possibly moderated by exposure to peer smoking. We investigated these relationships in a sample of 311 adolescents ages 13 – 21 presenting for well-visit medical appointments. Participants completed valid assessments of demographics, sports part...

Secondhand smoke (SHS) exposure is responsible for numerous diseases of the lungs and other bodily systems among children. In addition to the adverse health effects of SHS exposure, studies show that children exposed to SHS are more likely to smoke in adolescence. Susceptibility to smoking is a measure used to identify adolescent never-smokers who are at risk for smoking. Limited research has been conducted on the influence of SHS on susceptibility to smoking. The purpose of this study was to determine a robust measure of the strength of correlation between SHS exposure and susceptibility to smoking among never-smoking U.S. adolescents. This study used data from the 2009 National Youth Tobacco Survey to identify predictors of susceptibility to smoking in the full (pre-match) sample of adolescents and a smaller (post-match) sample created by propensity score matching. Results showed a significant association between SHS exposure and susceptibility to smoking among never-smoking adolescents in the pre-match (OR=1.47) and post-match (OR=1.52) samples. The odds ratio increase after matching suggests that the strength of the relationship was underestimated in the pre-match sample. Other significant correlates of susceptibility to smoking identified include: gender, race/ethnicity, personal income, smoke-free home rules, number of smoking friends, perception of SHS harm, perceived benefits of smoking, and exposure to pro-tobacco media messages. The use of propensity score matching procedures reduced bias in the post-match sample, and provided a more robust estimate of the influence of SHS exposure on susceptibility to smoking, compared to the pre-match sample estimates.

Passive Smoking in a Displacement Ventilated Room

DEFF Research Database (Denmark)

Bjørn, Erik; Nielsen, Peter V.

The aim of this research is to see if the displacement ventilation principle can protect a person from exposure to passive tobacco smoking. This is done by full-scale experiments with two breathing thermal manikins, smoke visualisations, and tracer gas measurements. In some situations, exhaled...... smoke will stratify in a certain height due to the vertical temperature gradient. This horizontal layer of exhaled tobacco smoke may lead to exposure. In other situations, the smoke is mixed into the upper zone, and the passive smoker is protected to some extent by the displacement principle...

Calibrating Self-Reported Measures of Maternal Smoking in Pregnancy via Bioassays Using a Monte Carlo Approach

Full Text Available Maternal smoking during pregnancy is a major public health problem that has been associated with numerous short- and long-term adverse health outcomes in offspring. However, characterizing smoking exposure during pregnancy precisely has been rather difficult: self-reported measures of smoking often suffer from recall bias, deliberate misreporting, and selective non-disclosure, while single bioassay measures of nicotine metabolites only reflect recent smoking history and cannot capture the fluctuating and complex patterns of varying exposure of the fetus. Recently, Dukic et al. [1] have proposed a statistical method for combining information from both sources in order to increase the precision of the exposure measurement and power to detect more subtle effects of smoking. In this paper, we extend the Dukic et al. [1] method to incorporate individual variation of the metabolic parameters (such as clearance rates into the calibration model of smoking exposure during pregnancy. We apply the new method to the Family Health and Development Project (FHDP, a small convenience sample of 96 predominantly working-class white pregnant women oversampled for smoking. We find that, on average, misreporters smoke 7.5 cigarettes more than what they report to smoke, with about one third underreporting by 1.5, one third under-reporting by about 6.5, and one third underreporting by 8.5 cigarettes. Partly due to the limited demographic heterogeneity in the FHDP sample, the results are similar to those obtained by the deterministic calibration model, whose adjustments were slightly lower (by 0.5 cigarettes on average. The new results are also, as expected, less sensitive to assumed values of cotinine half-life.

Full Text Available This paper investigates the impacts of smoke-free housing policies on compliance, enforcement and smoking behavior. From 2012 to 2014, we studied two affordable housing providers in Canada with comprehensive smoke-free policies: Waterloo Regional Housing that required new leases to be non-smoking and exempted existing leases, and Yukon Housing Corporation that required all leases (existing and new to be non-smoking. Focus groups and key informant interviews were conducted with 31 housing and public health staff involved in policy development and implementation, and qualitative interviews with 56 tenants. Both types of smoke-free policies helped tenants to reduce and quit smoking. However, exempting existing tenants from the policy created challenges for monitoring compliance and enforcing the policy, and resulted in ongoing tobacco smoke exposure. Moreover, some new tenants were smoking in exempted units, which undermined the policy and maintained smoking behavior. Our findings support the implementation of complete smoke-free housing policies that do not exempt existing leases to avoid many of the problems experienced by staff and tenants. In jurisdictions where exempting existing leases is still required by law, adequate staff resources for monitoring and enforcement, along with consistent and clear communication (particularly regarding balconies, patios and outdoor spaces will encourage compliance.

This study examined tobacco smoke pollution (also known as thirdhand smoke, THS) in hotels with and without complete smoking bans and investigated whether non-smoking guests staying overnight in these hotels were exposed to tobacco smoke pollutants. A stratified random sample of hotels with (n=10) and without (n=30) complete smoking bans was examined. Surfaces and air were analysed for tobacco smoke pollutants (ie, nicotine and 3-ethynylpyridine, 3EP). Non-smoking confederates who stayed overnight in guestrooms provided urine and finger wipe samples to determine exposure to nicotine and the tobacco-specific carcinogen 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone as measured by their metabolites cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), respectively. Compared with hotels with complete smoking bans, surface nicotine and air 3EP were elevated in non-smoking and smoking rooms of hotels that allowed smoking. Air nicotine levels in smoking rooms were significantly higher than those in non-smoking rooms of hotels with and without complete smoking bans. Hallway surfaces outside of smoking rooms also showed higher levels of nicotine than those outside of non-smoking rooms. Non-smoking confederates staying in hotels without complete smoking bans showed higher levels of finger nicotine and urine cotinine than those staying in hotels with complete smoking bans. Confederates showed significant elevations in urinary NNAL after staying in the 10 most polluted rooms. Partial smoking bans in hotels do not protect non-smoking guests from exposure to tobacco smoke and tobacco-specific carcinogens. Non-smokers are advised to stay in hotels with complete smoking bans. Existing policies exempting hotels from complete smoking bans are ineffective.

Lung cancer from radon and smoking: a multistage model for the WISMUT uranium miners

Full text: In the world's third-largest uranium-mining province located in areas of Saxony and Thuringia in the former German Democratic Republic, the WISMUT Company conducted extensive uranium mining starting in 1946. Up to 1990, when mining activities were discontinued, most of the 400,000 employees had been exposed to uranium ore dust and radon and its progeny. It is well established that, besides smoking, such exposures are associated with an increased risk of lung cancer. From about 130,000 known miners a huge cohort of 59,000 miners has been formed and in an epidemiological analysis lung cancer risks have been evaluated (Grosche et al., 2006). We will present an alternative approach using a biologically-based multistage carcinogenesis model quantifying the lung-cancer risk related to both the exposure to radon and smoking habits. This mechanistic technique allows for extrapolation to the low exposures that are important for present-day radiation protection purposes and the transfer of risk across populations. The model is applied to a sub-cohort of about 35,000 persons who were employed at WISMUT after 1955, with known annual exposures estimated from the job-exposure matrix (Lehmann et al., 2004). Unfortunately, detailed information on smoking is missing for most miners. However, this information has been retrieved in two case-control studies, one of which was nested in the cohort while the other was not (Brueske-Hohlfeld et al., 2006). For these studies, the relevant smoking parameters are assembled in so-called smoking spectra that are next projected onto the entire cohort using a Monte-Carlo sampling method. Individual smoking habits that are randomly assigned to the cohort members, together with the information on annual exposure to radon, is used as an input for the multistage model. Model parameters related to radon and tobacco exposure are fitted with a maximum-likelihood technique. We will show results of the observed and expected lung

Measurement of smoking: surveys and some recommendations.

A survey of smoking cessation researchers found considerable disagreement in the measurement procedures used to determine treatment outcome. The survey investigated (1) the duration of the measurement interval used to determine abstinence and smoking rate; (2) procedures for classifying people who smoke after treatment but are abstinent at follow-up; and (3) procedures for classifying people who use marijuana or tobacco products other than cigarettes. The marked disagreement among researchers' survey responses was compounded by the failure of their published articles to explain how smoking had been measured and scored. The Discussion identifies long-term abstinence as the most critical problem; its measurement was least consistent procedurally across studies yet most important for comparing them. Recommendations are made for establishing measurement and reporting conventions.

This paper summarizes results of empirical studies on cigarette advertising and promotions, antismoking advertising, product placement in movies, on television and in music media and news coverage about smoking. In addition, we provide an overview of some of the theoretical literature relevant to the study of media uses and effects. Finally, we discuss empirical findings in the context of these theories to draw some conclusions about media influences on smoking and identify issues for further research. We conclude that (a) the media both shape and reflect social values about smoking; (b) the media provide new information about smoking directly to audiences; (c) the media act as a source of observational learning by providing models which teenagers may seek to emulate; (d) exposure to media messages about smoking also provides direct reinforcement for smoking or not smoking; (e) the media promote interpersonal discussion about smoking; (f) the media can influence "intervening" behaviors that may make teenage smoking less likely; and (g) antismoking media messages can also set the agenda for other change at the community, state or national level. We outline priorities for further research which emphasize the need for longitudinal studies, multi-level studies, an awareness of the probably dynamic relationship between tobacco advertising and antismoking advertising, the importance of determining appraisal of tobacco industry youth smoking prevention efforts and the dearth of research on news coverage about smoking.

Full Text Available Periodontal disease has very complex and multi factor etiology. Plaque bacteria is the main cause of periodontal disease and another risk factor that also plays a role is a smoking habit. Cigarette product such as nicotine can influence the development of periodontal disease that can directly and systemically damage the function of PMN cell. The research was conducted by taking a clinical examination on the smoking influence that covers the number of cigarettes and the period of smoking, and kind of cigarette to the worse of periodontal disease, and by measuring the epithelial attachment loss and the bleeding index. The research was conducted to 152 male aged 20-45 years old, comprised 80 smokers and 72 nonsmokers at the Clinic of Faculty of Dentistry Universitas Indonesia, Jakarta. The result of the research showed that smoking gave influence on the worse of the periodontal disease. There was a profound relationship between the smoking period and the number of cigarettes consumed everyday indicated by the epithelial attachment loss. Smoking did not enhance gingival bleeding. The relationship between kinds of cigarette and the gingival bleeding score and the epithelial attachment loss did not show a significant bleeding.

Tobacco control prevention efforts are important to protect people from exposure to dangerous tobacco smoke, support cessation, and reduce tobacco-use initiation. While smoke-free laws have been a widespread tobacco control strategy, little work has been done to examine the impact of smoke-free school policies. The objective of this study is to evaluate the impact of provincial smoke-free school ground policies on youth-reported exposure to secondhand smoke (SHS) on school property. This study used a nationally representative sample of 20 388 youth aged 15-18 from the 2005-2012 Canadian Tobacco Use Monitoring Survey. A quasi-experimental design was used to evaluate the impact of smoke-free school policies on SHS exposure. Approximately over half (52%) of respondents reported SHS exposure on a school property in the past month. Smoke-free school policy had a statistically significant effect on SHS exposure. Specifically, the adoption of smoke-free school reduced the probability of SHS exposure by about 8 percentage points. Respondents who were smokers were more likely to report being exposed to SHS than nonsmokers. Likewise, those living in urban areas had higher probability of being exposed to SHS than those living in rural parts of Canada. Reported exposure to tobacco smoke did decrease after the introduction of smoke-free ground policies; however, almost half of high-school aged youth report exposure in the last month. Across Canada, provincial health authorities as well as school administers may need to assess the implementation of these smoke-free policies and improve enforcement strategies to further reduce exposure to dangerous SHS. © The Author 2015.

The aim of the paper was to determine the frequency and intensity of tobacco smoking by pregnant women as well as to find out the relationship between tobacco smoking during pregnancy and socioeconomic variables (education, marital status, professional career, smoking partner, number of children) as well as health variables (severe ailments during pregnancy period, taking medicines, using medical care). The research was carried out at the department of gynecology and obstetrics of the Specialist Hospital in Jasło as well as at the Women's Outpatient Clinic of the Public Independent Health Service Institution in Skołyszyn (Podkarpackie Voivodship). The research was conducted by means of the questionnaire distributed from July to September 2002 among 100 pregnant women. The results of the analysis indicate that 18% of the women under survey smoked cigarettes during pregnancy, including 6% daily smokers and 12% occasional smokers. 18% of women quitted smoking when they found out that they were pregnant, and 18% of them limited smoking. Exposure to passive smoking at their family home was declared by more than a half of the pregnant women, while 14% of the surveyed women mentioned passive exposure to smoke at their workplace. The socioeconomic variables that most clearly showed positive correlation with active smoking by pregnant women were: smoking tobacco by a husband or steady partner, smoking tobacco in the presence of a pregnant woman in her workplace and at home, as well as taking advantage of a family doctor's advice. Smoking tobacco during pregnancy was also enhanced by: the lower level of education, extramarital pregnancy, permanent residence in a town or a city, poor living conditions, not working professionally during pregnancy, having two or more children, abnormal course of pregnancy, suffering from such ailments as: weepiness, problems with relaxation, lack of appetite and taking no medicines during pregnancy.

The aim of this study was to provide evidence that ETS exposure from the husband at home has a more significant influence on the airway obstruction of nonsmoking women than other housemates. Participants and methods: Nonsmoking women aged 40 years or older were recruited from the health checkup during May 2015–December 2016, Japan. They answered structured questionnaires, including ETS exposure from their husbands and other housemates (parents, siblings and dependants, and performed spirometry. We categorized the women with any history of ETS exposure from housemates into three groups (A = husband, B = others and C = both of husband and others and defined the control group as those with no ETS exposure from housemates. Results: A total of 811 nonsmoking women completed questionnaires and spirometry. The proportion of nonsmoking women who had airway obstruction (forced expiratory volume in 1 second [FEV1]/forced vital capacity [FVC] <70% among Group A (7.5% was significantly higher than those in the control group (1.1%, p<0.01 and Group B (0.8%, p<0.01.

Full Text Available This study aimed to gain insight into the impact of lung conditions on smoking behaviour and smoking cessation, and identify recommendations for smoking cessation and professional-patient communications. The study was led by the European Lung Foundation in collaboration with the European Respiratory Society Task Force on “Statement on smoking cessation on COPD and other pulmonary diseases and in smokers with comorbidities who find it difficult to quit”. A web-based observational cross-sectional questionnaire was developed from a patient-centered literature review. Topics covered were: cohort characteristics; perspectives on smoking cessation; interactions with healthcare professionals; and recommendations to improve cessation outcomes. The questionnaire was disseminated via existing patient and professional networks and social media channels. The survey was available online for a period of 4 months in 16 languages. The data were analysed as a whole, not by country, with thematic analysis of the open responses. Common characteristics were: male (54%; age 40–55 years (39%; 11–20 cigarettes a day (39%; smokes within 30 min of waking (61%; and has made 1–5 cessation attempts in the previous 12 months (54%. 59% had tried cessation treatments, but, of these, 55% had not found any treatments helpful. Recommendations were: earlier intervention; discussion of the patient's smoking beliefs, behaviours and motivation; giving constructive advice; understanding addiction; informed decision-making; and treatment options. Areas for new and further research have been highlighted through exploring the smoking cessation perspectives and recommendations of people with lung conditions in Europe who smoke.

Full Text Available Abstract Background Cigarette smoking has been associated with worse infertility treatment outcomes, yet some studies have found null or inconsistent results. Methods We followed 225 couples who underwent 354 fresh non-donor assisted reproductive technology (ART cycles between 2006 and 2014. Smoking history was self-reported at study entry. We evaluated the associations between smoking patterns and ART success using multivariable discrete time Cox proportional hazards models with six time periods: cycle initiation to egg retrieval, retrieval to fertilization, fertilization to embryo transfer (ET, ET to implantation, implantation to clinical pregnancy, and clinical pregnancy to live birth to estimate hazard ratios (HR and 95% CIs. Time-dependent interactions between smoking intensity and ART time period were used to identify vulnerable periods. Results Overall, 26% of women and 32% of men reported ever smoking. The HR of failing in the ART cycle without attaining live birth for male and female ever smokers was elevated, but non-significant, compared to never smokers regardless of intensity (HR = 1.02 and 1.30, respectively. Female ever smokers were more likely to fail prior to oocyte retrieval (HR: 3.37; 95% CI: 1.00, 12.73. Every one cigarette/day increase in smoking intensity for females was associated with a HR of 1.02 of failing ART (95% CI: 0.97, 1.08, regardless of duration or current smoking status. Women with higher smoking intensities were most likely to fail a cycle prior to oocyte retrieval (HR: 1.07; 95% CI: 1.00, 1.16. Among past smokers, every additional year since a man had quit smoking reduced the risk of failing ART by 4% (HR: 0.96; 95% CI: 0.91, 1.00 particularly between clinical pregnancy and live birth (HR: 0.86; 95% CI: 0.76, 0.96.

Despite a reduction in Federal regulatory activity, research concerned with flame retardancy and smoke suppression in the private sector appears to be increasing. This trend seem related to the increased utilization of plastics for end uses which traditionally have employed metal or wood products. As a result, new markets have appeared for thermally stable and fire resistance thermoplastic materials, and this in turn has spurred research and development activity. In addition, public awareness of the dangers associated with fire has increased as a result of several highly publicized hotel and restaurant fires within the past two years. The consumers recognition of flammability characteristics as important materials property considerations has increased. The current status of fire and smoke retardant chemistry and research are summarized.

This study extends research on receptivity to tobacco marketing over a key developmental period for cigarette smoking experimentation. The purpose of this study was to understand the effect of receptivity to tobacco marketing and exposure to friends who smoke on smoking experimentation. Participants were 10 to 13 years old who had never tried cigarettes (n = 878), interviewed six times at 8-month intervals. At baseline, 25% percent of the 10 and 11 years old in the sample of never smokers were receptive to tobacco marketing, while less than 5% had friends who smoked. Having a friend who smoked at study baseline and acquiring such friends for the first time during the study were the strongest predictors of smoking experimentation. Initial receptivity to tobacco marketing increased the risk of smoking experimentation independently of having friends who smoke at baseline or acquiring friends who smoke throughout the study period. The high level of receptivity observed even among 10 and 11 years old and its robust relationship with cigarette smoking experimentation independent of the significant risk associated with having friends who smoke suggests that successful prevention of receptivity may require intervention at an early age.

Potential Fuel Loadings, Fire Ignitions, and Smoke Emissions from Nuclear Bursts in Megacities

We consider the effects of "small" nuclear detonations in modern "megacities," focusing on the possible extent of fire ignitions, and the properties of corresponding smoke emissions. Explosive devices in the multi-kiloton yield range are being produced by a growing number of nuclear states (Toon et al., 2006), and such weapons may eventually fall into the hands of terrorists. The numbers of nuclear weapons that might be used in a regional conflict, and their potential impacts on population and infrastructure, are discussed elsewhere. Here, we estimate the smoke emissions that could lead to widespread environmental effects, including large-scale climate anomalies. We find that low-yield weapons, which emerging nuclear states have been stockpiling, and which are likely to be targeted against cities in a regional war, can generate up to 100 times as much smoke per kiloton of yield as the high-yield weapons once associated with a superpower nuclear exchange. The fuel loadings in modern cities are estimated using a variety of data, including extrapolations from earlier detailed studies. The probability of ignition and combustion of fuels, smoke emission factors and radiative properties, and prompt scavenging and dispersion of the smoke are summarized. We conclude that a small regional nuclear war might generate up to 5 teragrams of highly absorbing particles in urban firestorms, and that this smoke could initially be injected into the middle and upper troposphere. These results are used to develop smoke emission scenarios for a climate impact analysis reported by Oman et al. (2006). Uncertainties in the present smoke estimates are outlined. Oman, L., A.

To conduct analyses to determine the extent to which YouTube videos posted specific to smoking cessation were actually about quitting smoking and if so, whether or not they portrayed evidence-based practices (EBPs). In August 2008, researchers identified YouTube videos by search strategies, 'relevance' and 'view count' using the following three search terms: 'stop smoking', 'quit smoking' and 'smoking cessation (n=296 for full sample and n=191 for unique videos). Overall, almost 60% of videos contained a message about quitting smoking. Differences were found across search terms for videos about quitting smoking, with 'stop smoking' yielding the highest percentage (80.8%) of videos about quitting smoking. Almost half of the videos (48.9%) contained EBPs for cessation strategies; however, a significant portion contained either non--EBPs (28.4%) or both EBPs and non-EBPs (22.7%). The number of views per an individual video across the six categories ranged from a low of 8 in the 'relevance' strategy and 'smoking cessation' search term to a high of 1,247,540 in the 'view count' strategy and 'stop smoking' search term. Of the top three most viewed videos by strategy and search term, 66.7% included a specific mention of quitting smoking and, of these, the majority included EBPs. Results highlight the need to develop and upload videos containing EBPs both to increase the overall proportion of EBP videos in all categories, particularly in 'quit smoking' and 'stop smoking.' Research is needed to study whether YouTube videos influence knowledge, attitudes and behaviours regarding quitting smoking.

Secondhand smoke, which is also referred to as environmental tobacco smoke and passive smoke, is a known human carcinogen. Secondhand smoke also causes disease and premature death in nonsmoking adults and children. We summarize studies of secondhand smoke in public places before and after smoking bans, as well as studies of cardiovascular and respiratory disease before and after such bans. To protect the public from the harmful effects of secondhand smoke, smoke-free legislation is an effective public health measure. Smoking bans in public places, which have been implemented in many jurisdictions across the U.S. and in other countries, have the potential to influence social norms and reduce smoking behavior. Through legislative smoking bans for reducing secondhand smoke exposure and smoking prevalence, opportunities exist to protect the health of Georgians and other Americans and to reduce health care costs. These opportunities include increasing the comprehensiveness of smoking bans in public places and ensuring adequate funding to quit line services.

Non-daily, or intermittent smokers (ITS), are increasingly prevalent. Their smoking may be more situational than that of daily smokers (DS), and thus is hypothesized to be more influenced by cues. To assess ITS' response to cues, and compare it to that of DS. Samples of 239 ITS and 207 DS (previously reported in Shiffman et al. 2012a) were studied in 2,586 laboratory cue-reactivity sessions. Craving (Questionnaire of Smoking Urges) and smoking (probability, latency, puff parameters, and carbon monoxide increases) in response to cues was assessed following exposure to neutral cues and cues related to smoking, alcohol, negative affect, positive affect, and smoking prohibitions. Mixed effects models, generalized estimating equations and random-effects survival analyses were used to assess response to cues and differences between DS and ITS. ITS' craving increased following exposure to smoking and alcohol cues and decreased following positive affect cues, but cues had little effect on smoking behaviors. Cue reactivity was similar in ITS and DS. Among ITS, craving intensity predicted smoking probability, latency, and intensity, and the effects on latency were stronger among ITS than DS. Contrary to hypotheses, ITS were not more responsive to laboratory cues than DS. Results show that ITS do experience craving and craving increases that are then associated with smoking.

The impact of airway obstruction of nonsmoking women caused by their husband's smoking is unclear, despite the association between environmental tobacco smoke (ETS) exposure at home and obstructive pulmonary diseases among nonsmoking women. The aim of this study was to provide evidence that ETS exposure from the husband at home has a more significant influence on the airway obstruction of nonsmoking women than other housemates. Nonsmoking women aged 40 years or older were recruited from the health checkup during May 2015-December 2016, Japan. They answered structured questionnaires, including ETS exposure from their husbands and other housemates (parents, siblings and dependants), and performed spirometry. We categorized the women with any history of ETS exposure from housemates into three groups (A = husband, B = others and C = both of husband and others) and defined the control group as those with no ETS exposure from housemates. A total of 811 nonsmoking women completed questionnaires and spirometry. The proportion of nonsmoking women who had airway obstruction (forced expiratory volume in 1 second [FEV 1 ]/forced vital capacity [FVC] <70%) among Group A (7.5%) was significantly higher than those in the control group (1.1%, p <0.01) and Group B (0.8%, p <0.01). The proportion of airway obstruction in Group C (6.4%) was also higher than that in the control group ( p <0.05) and Group B ( p <0.05). ETS exposure from husband (odds ratio [OR], 3.53; 95% confidence interval [CI], 1.48-8.42) remained strongly associated with airway obstruction after multiple logistic regression analysis, adjusting for age, housemate's smoking habits, family history and ETS exposure in childhood and at work. Nonsmoking women who were exposed to ETS from their husband had the lowest FEV 1 /FVC, and a higher proportion of them had airway obstruction when compared to nonsmoking women who experienced ETS from housemates other than their husbands. The findings suggest that tobacco control in

Tobacco-related deaths in Vietnam are forecast to climb from 40 000 annually to 70 000 by 2030. Previous research in Western nations has found social factors to be important determinants of adolescent smoking. Because these factors remain unexplored in Vietnamese youth, the purpose of this study was to examine social normative beliefs regarding smoking in a school-based sample of North Vietnamese adolescents and the association of these factors with smoking behavior and susceptibility to smoking. Three measures of normative beliefs regarding smoking were evaluated in cross-sectional surveys of secondary students. Of the 3 measures, parent/peer disapproval was the most consistent normative belief associated with smoking behavior and susceptibility to smoking. Youth smoking prevention programs should consider assessing and taking into account normative beliefs and develop strategies that provide accurate information about the actual prevalence of smoking, the types of individuals who smoke, and approval/disapproval of smoking by parents and peers.

Full Text Available Abstract Background Despite knowledge of the adverse health effects of passive smoking, children are still being exposed. Children's nurses play an important role in tobacco preventive work through dialogue with parents aimed at identifying how children can be protected from environmental tobacco smoke (ETS exposure. The study describes the experiences of Child Health Care (CHC nurses when using the validated instrument SiCET (Smoking in Children's Environment Test in dialogue with parents. Method In an intervention in CHC centres in south-eastern Sweden nurses were invited to use the SiCET. Eighteen nurses participated in focus group interviews. Transcripts were reviewed and their contents were coded into categories by three investigators using the method described for focus groups interviews. Results The SiCET was used in dialogue with parents in tobacco preventive work and resulted in focused discussions on smoking and support for behavioural changes among parents. The instrument had both strengths and limitations. The nurses experienced that the SiCET facilitated dialogue with parents and gave a comprehensive view of the child's ETS exposure. This gave nurses the possibility of taking on a supportive role by offering parents long-term help in protecting their child from ETS exposure and in considering smoking cessation. Conclusion Our findings indicate that the SiCET supports nurses in their dialogue with parents on children's ETS exposure at CHC. There is a need for more clinical use and evaluation of the SiCET to determine its usefulness in clinical practice under varying circumstances.

Smoking in the movies increases adolescent smoking: a review.

Science.gov (United States)

Charlesworth, Annemarie; Glantz, Stanton A

2005-12-01

Despite voluntary restrictions prohibiting direct and indirect cigarette marketing to youth and paid product placement, tobacco use remains prevalent in movies. This article presents a systematic review of the evidence on the nature and effect of smoking in the movies on adolescents (and others). We performed a comprehensive literature review. We identified 40 studies. Smoking in the movies decreased from 1950 to approximately 1990 and then increased rapidly. In 2002, smoking in movies was as common as it was in 1950. Movies rarely depict the negative health outcomes associated with smoking and contribute to increased perceptions of smoking prevalence and the benefits of smoking. Movie smoking is presented as adult behavior. Exposure to movie smoking makes viewers' attitudes and beliefs about smoking and smokers more favorable and has a dose-response relationship with adolescent smoking behavior. Parental restrictions on R-rated movies significantly reduces youth exposure to movie smoking and subsequent smoking uptake. Beginning in 2002, the total amount of smoking in movies was greater in youth-rated (G/PG/PG-13) films than adult-rated (R) films, significantly increasing adolescent exposure to movie smoking. Viewing antismoking advertisements before viewing movie smoking seems to blunt the stimulating effects of movie smoking on adolescent smoking. Strong empirical evidence indicates that smoking in movies increases adolescent smoking initiation. Amending the movie-rating system to rate movies containing smoking as "R" should reduce adolescent exposure to smoking and subsequent smoking.

No smoking here: examining reasons for noncompliance with a smoke-free policy in a large university.

Jancey, Jonine; Bowser, Nicole; Burns, Sharyn; Crawford, Gemma; Portsmouth, Linda; Smith, Jennifer

2014-07-01

A large Australian university introduced a campuswide smoke-free policy in 2012. Almost 1 year after implementation, reasons for noncompliance among people observed smoking on campus were examined. Six smoking locations on campus were identified after a campuswide audit of smoking indicators (i.e., discarded cigarette butts packets and people observed smoking). At these locations, those observed smokers were interviewed. Interview responses were examined to elicit underlying themes. Fifty people were seen smoking during the observation period. Those smokers interviewed comprised staff (27%) and students (73%) aged between 18 and 24 (45.9%). The majority of the students were international students (51.8%). All respondents acknowledged their awareness of the smoke-free policy. Five explanatory themes for noncompliance emerged: defiance against the policy's perceived threat to self-governance; inconvenience to travel off campus to smoke; smoking as a physiological necessity; unintentional noncompliance through unawareness or confusion of policy boundaries; and ease of avoidance of detection or exposing others to cigarette smoke. Creating a culture of compliance at the university remains a significant challenge, especially considering the size of the campus, the high proportion of international students, and the logistics associated with monitoring smoking behavior in outdoor areas and on-campus student housing. © The Author 2014.

Research on sexual orientation and substance use has established that lesbian, gay, and bisexual (LGB) individuals are more likely to smoke than heterosexuals. This analysis furthers the examination of smoking behaviors across sexual orientation groups by describing how same- and opposite-sex romantic attraction, and changes in romantic attraction, are associated with distinct six-year developmental trajectories of smoking. The National Longitudinal Study of Adolescent Health dataset is used to test our hypotheses. Multinomial logistic regressions predicting smoking trajectory membership as a function of romantic attraction were separately estimated for men and women. Romantic attraction effects were found only for women. The change from self-reported heterosexual attraction to lesbian or bisexual attraction was more predictive of higher smoking trajectories than was a consistent lesbian or bisexual attraction, with potentially important differences between the smoking patterns of these two groups.

2007-11-01

Recent research has shown that 10 min of moderate intensity exercise reduce smoking withdrawal symptoms and desire to smoke in acutely abstinent smokers. The aim of the current study was to determine whether the reductions are related to participant expectation of these effects. Forty-five sedentary participants who had smoked ten or more cigarettes per day for at least 3 years reported their expectation of the effects of exercise on smoking withdrawal symptoms. Approximately 1 month later, participants were randomly assigned to one of three groups after 11-15 h of overnight smoking abstinence. Each group read either a positive, negative or neutral statement concerning exercise effects on smoking withdrawal symptoms. They rated their expectation again and then completed 10 min of moderate intensity exercise on a stationary bicycle ergometer. Using standardised scales, participants rated smoking withdrawal symptoms and desire to smoke at 10, 5 and 0 min before exercise, then at 5 and 10 min during exercise and 15 and 20 min post-exercise. Expectation of exercise effects on withdrawal were manipulated in the predicted directions. No significant group main effects were found for any symptom. Significant reductions in symptoms and desire to smoke occurred during and after exercise regardless of participant expectation. Ten minutes of moderate intensity exercise can lead to reductions in desire to smoke and smoking withdrawal symptoms, which are not due to the participant's expectation of exercise effects. These findings support the use of short periods of exercise as an aid to smoking cessation.

The objective was to determine secondhand smoke (SHS) exposure with and without smoke-free laws in urban and rural communities. The research hypothesis was that SHS exposure in public places could be improved by smoke-free law regardless of urban and rural status. Indoor air quality in hospitality venues was assessed in 53 communities (16 urban and 37 rural) before smoke-free laws; 12 communities passed smoke-free laws during the study period. Real-time measurements of particulate matter with 2.5 µm aerodynamic diameter or smaller (PM2.5) were taken 657 times from 586 distinct venues; about 71 venues had both pre- and post-law measurements. Predictors of log-transformed PM2.5 level were determined using multilevel modeling. With covariates of county-level percent minority population, percent with at least high school education, adult smoking rate, and venue-level smoker density, indoor air quality was associated with smoke-free policy status and venue type and their interaction. The geometric means for restaurants, bars, and other public places in communities without smoke-free policies were 22, 63, and 25 times higher than in those with smoke-free laws, respectively. Indoor air quality was not associated with urban status of venue, and none of the interactions involving urban status were significant. SHS exposure in public places did not differ by urban/rural status. Indoor air quality was associated with smoke-free law status and venue type. This study analyzed 657 measurements of indoor PM2.5 level in 53 communities in Kentucky, USA. Although indoor air quality in public places was associated with smoke-free policy status and venue type, it did not differ by urban and rural status. The finding supports the idea that population in rural communities can be protected with smoke-free policy. Therefore, it is critical to implement smoke-free policy in rural communities as well as urban areas.

The African American Youth Smoking Experience: An Overview.

2016-04-01

Beginning in the late 1970s, a very sharp decline in cigarette smoking prevalence was observed among African American (AA) high school seniors compared with a more modest decline among whites. This historic decline resulted in a lower prevalence of cigarette smoking among AA youth that has persisted for several decades. We synthesized information contained in the research literature and tobacco industry documents to provide an account of past influences on cigarette smoking behavior among AA youth to help understand the reasons for these historically lower rates of cigarette smoking. While a number of protective factors including cigarette price increases, religiosity, parental opposition, sports participation, body image, and negative attitudes towards cigarette smoking may have all played a role in maintaining lower rates of cigarette smoking among AA youth as compared to white youth, the efforts of the tobacco industry seem to have prevented the effectiveness of these factors from carrying over into adulthood. Continuing public health efforts that prevent cigarette smoking initiation and maintain lower cigarette smoking rates among AA youth throughout adulthood have the potential to help reduce the negative health consequences of smoking in this population. While AA youth continue to have a lower prevalence of cigarette smoking than white youth, they are still at risk of increasing their smoking behavior due to aggressive targeted marketing by the tobacco industry. Because AAs suffer disproportionately from tobacco-related disease, and have higher incidence and mortality rates from lung cancer, efforts to prevent smoking initiation and maintain lower cigarette smoking rates among AA youth have the potential to significantly lower lung cancer death rates among AA adults.

Maternal smoking during pregnancy is one of the most modifiable causes of morbidity and mortality for both pregnant women and their fetuses. The long-term effects of prenatal exposure to smoke on child behavior and development have been the subject of more extensive research than have the short-term effects. Therefore, the aim of this work is to examine the effects of smoke exposure during pregnancy on neonatal behavior, including in our study a group of mothers exposed to secondhand smoke. The behavior of 282 healthy full-term newborns was assessed using the Neonatal Behavior Assessment Scale (NBAS) at 48-72 h of life. Sixty-two mothers smoked during pregnancy (no mother smoked more than 15 cig/day) and 17 were exposed to secondhand smoke. After adjusting for socio-demographic and obstetric factors, both newborns whose mothers smoked and those whose mothers were exposed to secondhand smoke showed significantly lower scores in the habituation cluster than non-smoking mothers. Exposure to secondhand smoke was also related to lower motor system cluster scores as well as some supplementary items and the newborns of smoking mothers showed significantly lower scores in the state regulation cluster and in some items of the state organization cluster than the newborns of non-smoking mothers. We conclude that active and passive smoking during pregnancy affects several aspects of neurobehavioral development, regardless of socio-demographic, obstetric and pediatric factors.

Posttraumatic stress and emotion dysregulation: Relationships with smoking to reduce negative affect and barriers to smoking cessation.

Science.gov (United States)

Short, Nicole A; Oglesby, Mary E; Raines, Amanda M; Zvolensky, Michael J; Schmidt, Norman B

2015-08-01

Many cigarette smokers have experienced a traumatic event, and elevated posttraumatic stress symptoms (PTSS) are associated with increased smoking levels. Previous research has found that elevated PTSS are associated with smoking to cope with negative affect, and it has been posited that perceptions of being unable to cope with the consequences of smoking cessation interfere with smoking cessation in this population. However, the mechanism of the relationship between PTSS and these smoking maintenance factors (i.e., smoking to reduce negative affect and barriers to cessation) has not been established. Emotion dysregulation is one potential mechanism as it is associated with PTSS as well as addictive behavior aimed at avoiding and reducing negative emotional states. We cross-sectionally tested the hypotheses that 1) PTSS and emotion dysregulation would be incrementally associated with smoking to reduce negative affect and barriers to cessation, and 2) that emotion dysregulation would mediate the relationships between PTSS, smoking to reduce negative affect, and barriers to cessation among a community sample of trauma-exposed individuals presenting for smoking cessation treatment (N=315). Results demonstrated that elevated PTSS were associated with increased smoking to reduce negative affect and barriers to cessation, and that emotion dysregulation mediated these relationships. These findings provide evidence of a mechanism between PTSS and psychological smoking maintenance factors, and suggest that emotion dysregulation may be a useful target for smoking cessation interventions among trauma-exposed individuals.

Little research has been conducted to determine the psychosocial and behavioral impacts of smoke-free policies in middle-income countries. Cross-sectional data were analyzed from the 2006 waves of the International Tobacco Control Policy Evaluation. Survey comparing adult smokers in Mexico (n = 1,080), where smoke-free legislation at that time was weak, and Uruguay (n = 1,002), where comprehensive smoke-free legislation was implemented. Analyses aimed to determine whether exposure to smoke-free policies and perceived antismoking social norms were associated with smokers' receiving cues about the bothersome nature of secondhand smoke (SHS), with smokers' reactance against such cues, and with smokers' level of support for smoke-free policies in different venues. In bivariate analyses, Uruguayan smokers were more likely than Mexican smokers to experience verbal anti-SHS cues, lower reactance against anti-SHS cues, stronger antismoking societal norms, and stronger support for 100% smoke-free policies in enclosed workplaces, restaurants, and bars. In multivariate models for both countries, the strength of voluntary smoke-free policies at home was independently associated with support for smoke-free policies across all venues queried, except for in bars among Uruguayans. Perceived strength of familial antismoking norms was consistently associated with all indicators of the social acceptability of smoking in Uruguay but only with the frequency of receiving anti-SHS verbal cues in Mexico. These results are generally consistent with previous research indicating that comprehensive smoke-free policies are likely to increase the social unacceptability of smoking and that resistance against such policies is likely to diminish once such policies are in place.

Where there's smoke : health effects of wood smoke and risk reduction strategies

2005-07-01

This paper presents a summary of a discussion at a former workshop on smoke from both forest fires and wood stoves. Climate change is forecasted to increase the occurrence of forest fires in Canada and climate change mitigation measures may increase the use of wood stoves for home heating, resulting in an increase in respiratory and cardiovascular symptoms in the Canadian population. These health effects of wood smoke include: headaches and allergies; breathing difficulties; reduced lung function; aggravated heart disease; and increased susceptibility to lower respiratory tract infections. This paper also presented information on health effects of wood smoke and research recommendations for improved policies to protect human health. tabs., figs.

Is the smoking decision an 'informed choice'? Effect of smoking risk factors on smoking beliefs.

Science.gov (United States)

Leventhal, H; Glynn, K; Fleming, R

1987-06-26

The argument that people freely choose to smoke assumes that individuals at the point of initiation of smoking (often in adolescence) hold accurate beliefs about smoking. Smoking beliefs and the presence of known smoking risk factors were assessed in interviews with a sample of 895 urban young people. The respondents greatly overestimated the prevalence of adult and peer smoking, negative attitudes of their peers were greatly underestimated, a large proportion believed that they would be less likely than other people to contract a smoking-related illness if they became smokers, and there was a general lack of understanding of the adverse consequences experienced upon smoking cessation. These misperceptions were more common among youngsters who were smokers, who intended to smoke, or who had friends or family members who smoked. Because misinformation among young people is widespread and those at greatest risk for smoking are the most misinformed, the tobacco industry's argument that the decision to smoke reflects an "informed choice" is without merit.

'A real man smells of tobacco smoke'--Chinese youth's interpretation of smoking imagery in film.

Science.gov (United States)

Davey, Gareth; Zhao, Xiang

2012-05-01

Previous studies have associated youth's exposure to filmic images of smoking with real-life smoking acquisition; initial research in low- and middle-income countries confirms this relationship. The present study in Yunnan, southwest China sought answers to the following questions: How do young people in China make sense of smoking imagery they have seen in film? How are these perceptions shaped by the cultural and social context of images? How do these understandings relate to real-life tobacco use? A study with focus groups and grounded theory was conducted in 2010 and 2011 (Sept-Jan) with middle-school students ages 12 and 13 (n=68, focus groups=12, schools=6). Films and media literacy were important means through which knowledge about smoking was constructed and communicated. Film representations of smoking concurred with Chinese social behaviour (Confucian social networks, face-making, and the notion of society as a harmonious social unit), and were interpreted as congruent with real-life smoking. This pattern, in turn, was intertwined with perceived gender identities of smokers, gender-specific social behaviour, and willingness of girls to explore issues of gender equity. These findings lend new insights into interaction between smoking imagery in film and Chinese youth's smoking beliefs. Tobacco control programs in China should consider young people's interpretations of smoking and the ways they are nested in cultural and social milieu. Copyright © 2012 Elsevier Ltd.

Hanewinkel, R; Blohmke, S; Sargent, J D

2012-08-01

The aim of this study was to examine whether smoking in movies can predict established smoking in adolescence. A longitudinal study was conducted over a period of 13 months with 4112 German students. Adolescents' exposure to smoking in movies was assessed by asking each student to indicate which film he or she had seen from a unique list of 50 movies, which was randomly selected for each individual survey from a sample of 398 popular contemporary movies. We calculated exposure to movie smoking for each respondent by summing the number of smoking occurrences for each movie that the respondent reported seeing. At follow-up, a total of 272 young people had smoked more than 100 cigarettes during their lifetime. While 2.1% of the young people with the lowest exposure to movie smoking initiated established smoking, 13.4% of the group with the highest exposure to movie smoking initiated established smoking. The adjusted relative risk of initiation of established smoking was 2.05 times higher in the group with the highest movie smoking exposure compared to the group with the lowest exposure (95% confidence interval: 1.25-3.35). Our data indicate that smoking in movies can be regarded as an independent risk factor for the initiation of established smoking in adolescence. © Georg Thieme Verlag KG Stuttgart · New York.

Smoking habits and attitudes towards smoking among Estonian physicians.

Pärna, K; Rahu, K; Rahu, M

2005-05-01

This study examined the smoking habits and attitudes towards smoking among Estonian physicians. Cross-sectional data for 2668 physicians were gathered by a self-administered postal survey. The current smoking prevalence was 24.9% for male physicians and 10.8% for female physicians. The percentages of ex-smokers were 32.9 and 16.8%, respectively. Smoking prevalence among physicians was below the levels reported for the highest educational bracket of the total population in Estonia. Non-smoking physicians had more unfavourable views towards smoking than those who smoked. The majority of physicians were aware of the association between smoking and various diseases, with significant differences between smokers and non-smokers. Non-smoking physicians were more active in asking patients about smoking habits than those who smoked. Most Estonian physicians, especially those who smoked, failed to perceive themselves as positive role models. This study found a lower prevalence of smoking among physicians compared with the general population, and demonstrated the impact of personal smoking on physicians' attitudes towards smoking. The results provide an important challenge to medical education in Estonia.

Movie Smoking, Movie Horror, and Urge to Smoke

2010-01-01

It is known that exposure to smoking cues increases urge to smoke (UTS), but little is known about other media factors that might also increase UTS. We hypothesized that horror/thriller movies might also increase UTS by increasing negative affect. We surveyed 536 movie patrons who were smokers aged 18 years or older. Subjects had exited 26 movies, of which 12 contained smoking and two were horror films, one with and one without smoking. We used random effects regression to assess the association between exposure to movie smoking, movie horror, both and UTS, controlling for confounding factors. Median age was 26 years and 52% were female. Mean UTS was 5.9, 6.6, 6.6, and 8.7 for smokers exiting movies without smoking, with smoking, horror without smoking and horror with smoking respectively. Smoking in movies was associated with a significantly higher UTS (0.63 [95% CI 0.31–0.94]). Horror with smoking increased UTS by 2.8 points (95% C.I. 2.3, 3.5); the horror without smoking estimate was 0.88, but not statistically significant. This short report offers preliminary evidence that movie horror as one factor besides visual smoking cues that could increase UTS in a community setting. PMID:20301876

Counteracting the Influence of Peer Smoking on YouTube.

2017-04-01

YouTube, a popular online site for user-generated content, is emerging as a powerful source of peer modeling of smoking. Previous research suggests that in counteracting such influence, health messages may inadvertently increase the perceived prevalence of drug use (a descriptive norm) without reducing its acceptability (injunctive norm). This research tested the ability of health messages to reduce the social acceptability of peer smoking on YouTube despite enhancing its perceived prevalence. In an online experiment with 999 adolescents, participants were randomly assigned to view one of two videos: (a) a mosaic displaying a variety of YouTube videos of adolescents smoking followed by a message about the mortality risk to those smokers, or (b) a control video on a health topic unrelated to smoking. Although exposure to the adolescent YouTube smokers increased perceived prevalence among some participants, it simultaneously increased beliefs about smoking's adverse health outcomes and negative attitudes toward smoking, effects that were associated with reductions in injunctive norms of social acceptability. Interventions that communicate the severity and scope of health risks associated with smoking may undercut the descriptive normative effects of peer modeling of smoking on social media sites such as YouTube.

The prevalence of smoking is higher in Latvia than in most EU countries. This study aimed to determine the level of knowledge of dental students in Latvia about the effects of smoking on oral health and their attitudes toward smoking and its cessation. A cross-sectional survey among all the dental students in Latvia was conducted in 2011. Students at the Riga Stradins University were asked to participate in this anonymous, voluntary survey. The questionnaire included items concerned with the students' own smoking habits, their knowledge of smoking as an addiction and its health effects and their attitudes towards its prevention and cessation in a dental setting. The response rate was 87% (173/200). The Chi-square test and logistic regression were used for the statistical analyses. About one quarter of the students (24%) were daily or occasional smokers and almost half of the male students (46%) had smoked at least 100-times in their lifetime. The students revealed a lack of knowledge about the addictive nature of smoking, in that about half of the students did not consider smoking physically or socially addictive. About one fifth (21.4%) didn't consider environmental tobacco smoke (ETS) harmful to one's health. Although the students' awareness of smoking improved during their studies, the most significant factor related to their knowledge was their own smoking history (OR=2.7; p=0.021). Smoking was frequent among undergraduate dental students and they lacked knowledge of its addictiveness. More emphasis ought to be placed on education with regard to smoking and on cessation services.

To estimate the prevalence of tobacco use, exposure to secondhand smoke, and smoking restrictions in the home and workplace among residents of Tijuana, one of Mexico's largest cities. This cross-sectional household survey was conducted in Tijuana, Baja California, Mexico, during 2003 and 2004. A population-based sample of 400 Tijuana adult residents responded to a tobacco survey, and 397 of the surveys were analyzed. About 22.9% (95% confidence interval (CI): 18.7%-27.1%) of Tijuana adults reported current smoking, and 53.9% (95% CI: 48.8%-58.9%) reported chronic exposure to secondhand smoke. Approximately 44.4% (95% CI: 37.9%-50.9%) of Tijuana adults had a nonsmoking policy in their workplace, while 65.8% (95% CI: 61.0%-70.6%) of Tijuana households were smoke-free. The results underline the need for increased tobacco control efforts, particularly stricter enforcement of existing passive smoking regulations, in order to expand protection from secondhand smoke from private settings to public ones and to curb the tobacco epidemic in Tijuana and elsewhere in Mexico.

Full Text Available The aim of the study was to evaluate the habits and frequency of cigarette smoking. The study included 112 participants. In the study group, 67,64% of respondents were females whereas 32,36% were males. The age of participants ranged from 15 to 26 years. The study conducted in the period from January 2017 to February 2017 and it employed standardized interview research method. Research tool, which was used for data collection was a questionnaire consisted of 16 questions single-choice or multiple- choice questions. Statistical analysis was performed using the chi-square test. All values for which p <0.05 (probability of error were considered statistically significant. In the study group 28.8% of respondents answered that they smoked cigarettes in the past, while smoking a cigarette at the moment declared by 12.6% of people. Half of the respondents smoked about 10 cigarettes a day. Over 60% of respondents declared to start smoking over 18 years of age. More than 30% of respondents smoked e-cigarettes. Almost 100% of the respondents aware of the dangers of smoking. Over ¾ respondents have ever tried to break up with addiction. The respondents were asked where they most often they smoke cigarettes. Nearly half (46.9% of the respondents choose a public place as the place where cigarettes are most commonly smoked (work, school. Nearly half of the respondents (46.9% indicated that at least one parent in the household smokes cigarettes. However, only 9.74% of respondents said they smoked cigarettes at home with the company of a family. The question "What prompted you to first try a cigarette?" The most common answer was the "curiosity" and "friends suggestion" (78,1%. As many as 46.9% of respondents say that stress increases the number of smoked cigarettes.

Results of the Global Adult Tobacco Survey in Kerala, India found that 42 % of adults were exposed to second hand smoke (SHS) inside the home. Formative research carried out in rural Kerala suggests that exposure may be much higher. Numerous studies have called for research and intervention on SHS exposure among women and children as an important component of maternal and child health activities. Community-based participatory research was carried out in Kerala. First, a survey was conducted to assess prevalence of SHS exposure in households. Next, a proof of concept study was conducted to develop and test the feasibility of a community-wide smoke free homes initiative. Educational materials were developed and pretested in focus groups. After feasibility was established, pilot studies were implemented in two other communities. Post intervention, surveys were conducted as a means of assessing changes in community support. At baseline, between 70 and 80 % of male smokers regularly smoked inside the home. Over 80 % of women had asked their husband not to do so. Most women felt powerless to change their husband's behavior. When women were asked about supporting a smoke free homes intervention, 88 % expressed support for the idea, but many expressed doubt that their husbands would comply. Educational meetings were held to discuss the harms of second hand smoke. Community leaders signed a declaration that their community was part of the smoke free homes initiative. Six months post intervention a survey was conducted in these communities; between 34 and 59 % of men who smoked no longer smoked in their home. The smoke free homes initiative is based on the principle of collective efficacy. Recognizing the difficulty for individual women to effect change in their household, the movement establishes a smoke free community mandate. Based on evaluation data from two pilot studies, we can project that between a 30 and 60 % reduction of smoking in the home may be achieved, the

The research work explores the Electromagnetic and Acoustic Properties of Smoke Particulates from real fires, and the initial development of an alternative method of smoke detection based on the study work. The research was entirely self-funded including the purchase of the experimental apparatus, test equipment and calibration to international standards. The study includes the properties of solid and liquid post combustion particulates in air suspension forming smoke plumes, and the associated fluid flow dynamics. As part of the study the electromagnetic and acoustic properties of smoke particulates, a somewhat unique detection method described as the ''Double Matrix Board System'' was developed and used. It was initially developed to assist in the electromagnetic study work, and was later modified to examine the acoustic properties. The published results of the research on the ''Double Matrix Board System'' and the details of the patent application for the device are included in the Appendices to the Thesis document. (author)

The Impact of a City-Wide Indoor Smoking Ban on Smoking and Drinking Behaviors Across Emerging Adulthood.

Almost one-third of college students report recent cigarette use, primarily as "social smoking," and often in conjunction with alcohol use. While city-wide indoor smoking bans effectively reduce the number of social opportunities to smoke (eg, bars and music clubs), little is known about how these bans may impact the smoking behaviors of college students. Furthermore, nothing is known about how indoor smoking bans may impact students' drinking behaviors. The current study aims to determine the impact of a city-wide comprehensive indoor smoking ban on smoking and alcohol behaviors among a longitudinal sample of emerging adults. Data are from a 6-year longitudinal study (10 waves of data collection) that began the summer before college enrollment. Participants (N = 2244; 60% female) reported on their past 3-month smoking and drinking behaviors using Internet-based surveys at each wave. Piecewise linear growth modeling was used to determine how a city-wide comprehensive indoor smoking ban (implemented in the Fall of 2005 between Waves 4 and 5) impacted smoking frequency, cigarette quantity, drinking frequency, and number of binge drinking episodes. Smoking and alcohol use increased from the summer before college through the semester before implementation of the city-wide smoking ban. While smoking frequency (P < .001) and cigarette quantity (P < .05) declined after the ban, drinking frequency increased (P < .001) and the number of binge drinking episodes remained stable. Current findings suggest that comprehensive indoor smoking bans can influence the smoking behaviors of emerging adults, whereas trajectories of drinking are relatively unchanged. © The Author 2015.

Attentional bias towards smoking-related cues is increased during abstinence and can predict relapse after quitting. Exercise has been found to reduce cigarette cravings and desire to smoke during temporary abstinence and attenuate increased cravings in response to smoking cues. To assess the acute effects of exercise on attentional bias to smoking-related cues during temporary abstinence from smoking. In a randomized cross-over design, on separate days regular smokers (n = 20) undertook 15 minutes of exercise (moderate intensity stationary cycling) or passive seating following 15 hours of nicotine abstinence. Attentional bias was measured at baseline and post-treatment. The percentage of dwell time and direction of initial fixation was assessed during the passive viewing of a series of paired smoking and neutral images using an Eyelink II eye-tracking system. Self-reported desire to smoke was recorded at baseline, mid- and post-treatment and post-eye-tracking task. There was a significant condition x time interaction for desire to smoke, F((1,18)) = 10.67, P = 0.004, eta(2) = 0.36, with significantly lower desire to smoke at mid- and post-treatment following the exercise condition. The percentage of dwell time and direction of initial fixations towards smoking images were also reduced significantly following the exercise condition compared with the passive control. Findings support previous research that acute exercise reduces desire to smoke. This is the first study to show that exercise appears to also influence the salience and attentional biases towards cigarettes.

Upregulation of contractile endothelin type B receptors by lipid-soluble cigarette smoking particles in rat cerebral arteries via activation of MAPK

Cigarette smoke exposure increases the risk of stroke. However, the underlying molecular mechanisms are poorly understood. Endothelin system plays key roles in the pathogenesis of stroke. The present study was designed to examine if lipid-soluble (dimethyl sulfoxide-soluble) cigarette smoke particles (DSP) induces upregulation of contractile endothelin type B (ET B ) receptors in rat cerebral arteries and if activation of mitogen activated protein kinase (MAPK) and nuclear factor-kappaB (NF-κB) mediate the upregulation of contractile endothelin receptors in the cerebral arteries. Rat middle cerebral arteries were isolated and organ cultured in serum free medium for 24 h in the presence of DSP with or without specific inhibitors: MEK specific (U0126), p38 specific (SB202190), JNK specific (SP600125), NF-κB specific (BMS-345541) or (IMD-0354), transcription inhibitor (actinomycin D), or translation blocker (cycloheximide). Contractile responses to the ET B receptor agonist sarafotoxin 6c were investigated by a sensitive myograph. The expression of the ET B receptors were studied at mRNA and protein levels using quantitative real time PCR and immunohistochemistry, respectively. Results show that organ culture per se induced transcriptional upregulation of contractile ET B receptors in the cerebral vascular smooth muscle cells. This upregulation was further increased at the translational level by addition of DSP to the organ culture, but this increase was not seen by addition of nicotine or water-soluble cigarette smoke particles to the organ culture. The increased upregulation of contractile ET B receptors by DSP was abrogated by U0126, SP600125, actinomycin D, and cycloheximide, suggesting that the underlying molecular mechanisms involved in this process include activation of MEK and JNK MAPK-mediated transcription and translation of new contractile ET B receptors. Thus, the MAPK-mediated upregulation of contractile ET B receptors in cerebral arteries might be a

Previous research has shown reductions in cigarette consumption during the pre-quit period of exercise-aided smoking cessation interventions. Smoking topography and sensation patterns during this period is unknown and may provide valuable insight into compensation and cessation readiness. Female smokers (N = 236, M age = 43, M cigarettes/day = 17.0) enrolled in an exercise-aided smoking cessation intervention self-reported daily cigarette use and cigarette sensory experiences. Breath carbon monoxide and smoking topography data were collected during the period leading up to the targeted quit date (i.e., baseline, week 1, and week 3), which was set for week 4. Repeated measures ANOVAs revealed that cigarette consumption (p smoking satisfaction (p exercise during the pre-quit period served as a conduit for facilitating behavioral and sensory harm reduction with cigarettes. Furthermore, the pattern of change observed between cigarette consumption and smoking topography does not support compensation. These findings imply that female smokers who exercise prior to a quit attempt are in a favourable state to achieve cessation. Copyright © 2018 Elsevier Ltd. All rights reserved.

Aerobic exercise has been proposed as a stand-alone or adjunct smoking cessation treatment, but findings have been mixed. Laboratory studies have shown that individual exercise sessions lead to decreases in withdrawal symptoms and cigarette cravings, but findings are limited by lack of follow-up and artificial settings. On the other hand, smoking cessation treatment RCTs have generally failed to show positive effects of exercise on smoking cessation, but have been plagued by poor and/or unverified compliance with exercise programs. This paper describes the rationale and design for Quit for Health (QFH)--an RCT designed to determine the efficacy of aerobic exercise as an adjunct smoking cessation treatment among women. To overcome limitations of previous research, compliance with the exercise (and wellness contact control) program is incentivized and directly observed, and ecological momentary assessment is used to examine change over time in withdrawal symptoms and cigarette cravings in participants' natural environments.

On January 1, 2008, the French government implemented a national ban on indoor smoking in hospitality venues. Survey results indicate the indoor ban has been successful at dramatically reducing indoor smoking; however, there are reports of an increased number of outdoor hospitality spaces (patios) where smoking can take place. This study sought to understand if the indoor ban simply moved smoking to the outdoors, and to assess levels of support for smoking restrictions in outdoor hospitality settings after the smoke-free law. Telephone interviews were conducted among 1067 adult smokers before and after the 2008 indoor ban as part of the International Tobacco Control (ITC) France Survey. Among other topics, this survey measures how the smoking ban has influenced smoking behaviour relevant to outdoor sections of hospitality venues. In addition, 414 non-smoking adults and 164 respondents who had quit smoking between waves were also asked about support for outdoor smoking restrictions. Reported smoking outdoors at cafés/pubs/bars increased from 33.6% of smokers at Wave 1 to 75.9% at Wave 2. At restaurants, smoking outdoors increased from 28.9% to 59.0%. There was also an increase in reported non-smoking for both visits to cafés/pubs/bars, and restaurants from 13.4% to 24.7%, and 30.4% to 40.8% respectively. The majority of smokers (74.5%), non-smokers (89.4%) and quitters (74.0%) support a partial or complete ban on smoking in outdoor areas of restaurants. The indoor smoking ban moved smoking to outdoor spaces; however, the ban is also associated with increased non-smoking behaviour. The majority of respondents support outdoor smoking restrictions in patio environments.

School connectedness and susceptibility to smoking among adolescents in Canada.

Azagba, Sunday; Asbridge, Mark

Smoking susceptibility in early adolescence is strongly predictive of subsequent smoking behavior in youth. As such, smoking susceptibility represents a key modifiable factor in reducing the onset of smoking in young people. A growing literature has documented a number of factors that influence susceptibility to smoking; however, there is limited amount of research examining associations of susceptibility to smoking and school connectedness. The current study examines whether school connectedness has an independent protective effect on smoking susceptibility among younger adolescents. A nationally representative sample of 12,894 Canadian students in grades 6-8 (11-14 years old), surveyed as part of the 2010-2011 Youth Smoking Survey, was analyzed. Multilevel logistic regression models examined unadjusted and adjusted associations between school connectedness and smoking susceptibility. The impacts of other covariates on smoking susceptibility were also explored. Approximately 29% of never-smokers students in grades 6-8 in Canada were susceptible to future smoking. Logistic regression analysis, controlling for standard covariates, found that school connectedness had strong protective effects on smoking susceptibility (odds ratio [OR] 0.91, 95% CI 0.89-0.94). The finding that school connectedness is protective of smoking susceptibility, together with previous research, provides further evidence that improving school conditions that promote school connectedness could reduce risky behavior in adolescents. While prevention efforts should be directed at youth of all ages, particular attention must be paid to younger adolescents in the formative period of 11-14 years of age.

You probably have mixed feelings about going into labor. On one hand, bringing a new life into the world is really exciting. On the other, it can be really scary to have a baby, especially if this is your first child. Unfortunately, it can be even scarier if you smoke. Research shows that smoking during pregnancy can lead to serious complications for you and your baby during labor and delivery.

Two-thirds of complaints received by the Hong Kong Environmental Protection Department in 1988 were related to poor air quality. In July 1990 legislation was implemented to reduce fuel sulphur levels. The intervention led to a reduction in respiratory symptoms and bronchial hyperresponsiveness of primary school children. The objectives of this study were to investigate the differences in respiratory health between non-smoking women living in the more polluted district (Kwai Tsing) and those living in the less polluted district (Southern); to assess the impact of the government air quality intervention; and to study the effect of environmental tobacco smoke on respiratory health in non-smoking women in both districts. A total of 3405 non-smoking women, aged 36.5 years (standard deviation = 3.0), from two districts with good and poor air quality respectively before the intervention were followed yearly from 1989 to 1991. Binary latent variable modelling was used to summarize the six respiratory symptoms and to estimate the effects of risk factors. In 1989, living in the polluted district was associated with poor respiratory health (odds ratio [OR] = 1.55, 95% confidence interval [CI]: 1.11-2.17, P 0.241) in the more polluted compared with the less polluted district for poor respiratory health. In 1989, the effects on poor respiratory health for exposure to two or more categories of smokers relative to none in the home (OR = 1.80, 95% CI: 1.15-2.83, P living in polluted relative to less polluted district (95% CI of the two effects overlapping each other). Environmental tobacco smoke (ETS) and outdoor air pollution had independent adverse effects on respiratory health of non-smoking women and improvement in air quality had produced some but non-significant benefits.

Smoking habits and smoking cessation among North Carolina nurses.

Swenson, I E

1989-01-01

A 1987 questionnaire survey of a 1% random sample (n = 356) of registered nurses in North Carolina provided data on the smoking habits and smoking cessation. Fifty-six percent were never smokers; 19% were current smokers. Among the ever smokers, 31% had quit smoking for at least one year. Twenty-two percent of the former smokers had smoked less than 5 years and 39% less than 10 years before quitting. Anecdotal notes from never smokers suggested that their major deterrent to smoking was their own parents smoking. Concerns about the addictive smoking behavior and health effects of smoking observed in their parents as well as concerns about potential health risks to themselves deterred them from smoking. Concerns about the adverse consequences of smoking was the most influential factor influencing smoking cessation and reduction of cigarette smoking. Friends' and family's encouragement to stop smoking was the most influential external factor motivating nurses to quit or reduce cigarette consumption. Fifty-seven percent of the former smokers quit smoking after one or two attempts while 53 of the current smokers had tried to quit 3 or more times - 90% had tried at least once to quit smoking; however, only 18% of the current smokers had abstained for more than one year during any of their attempts to quit. Implications of the results include: (1) smoking cessation programs for nurses in the workplace may have considerable impact since the majority of nurses who smoke are tying to quit; (2) relapse prevention strategies need to be an integral part of such smoking cessation programs including involvement of family and friends to support the smokers in their cessation efforts.

Full Text Available Abstract Background The main objectives of this study are to describe the smoked cocaine user's profile in socially-depressed areas and their needs from a harm-reduction perspective, to investigate their use of smoking crack and compare the acute effects between injecting and smoking consumption. Methods The study took place in SAPS, Barcelona, Spain. Two focus group sessions were undertaken with a total of 8 drug users. Secondly, the 8 participants answered a structured questionnaire and in the course of the sessions, as a snowball activity, were trained to survey 6 other crack smokers. Results We obtained 56 questionnaires. The majority of participants were from non-European Community countries (62.69%, 70.2% of participants referred to sharing the smoking equipment. The most frequent symptoms reported during smoked cocaine were mydriasis (83.33%, perspiration (72.92% and compulsive object search (70.83% During the group sessions, participants said that smoked cocaine is much more addictive than injected cocaine and causes more anxiety. Participants also reported the difficulty of changing from injected use to smoked use, due to the larger amount of cocaine needed to reach the same effects as when having injected. Conclusions We can conclude that the research, focused on achieving greater knowledge of the smoked cocaine user's profile, their usage of smoking crack, consumption patterns and acute effects, should be incorporated into substance misuse interventions.

Smoking behaviour in youth: the problem of low self-esteem?

Science.gov (United States)

Glendinning, A; Inglis, D

1999-10-01

The study considers the relationship between self-esteem and smoking in youth. Research has emphasized the need for ecological perspectives on health behaviours, for example, the context and meaning of cigarette smoking in young people's lives. Recent Scottish research, utilizing a range of methodologies, has examined the peer group context and smoking. The convergence of findings is striking. It would appear that different social groupings exist within the peer context, where these are tied to peer status and associated with distinctive lifestyle practices, and dispositions, including smoking. In the case of self-esteem and smoking the results from conventional, survey-based research have often been inconclusive, the suggestion being that global measures of self-esteem are insufficient, since feelings of self-esteem are domain or context specific. However, the present study analyses survey data from two Scottish samples of 13-14-year-olds, conducted some 10 years apart, one national (n=2100, 1987) and the other rural (n=800, 1996) to show that even with the bluntest of research instruments, i.e. self-report questionnaire survey data and general measures, it is possible to elaborate on the relationship between self-esteem and cigarette smoking in youth.

Are Smoking Cessation Treatments Associated with Suicidality Risk? An Overview

2016-01-01

Full Text Available Risk of suicidality during smoking cessation treatment is an important, but often overlooked, aspect of nicotine addiction research and treatment. We explore the relationship between smoking cessation interventions and suicidality and explore common treatments, their associated risks, and effectiveness in promoting smoking reduction and abstinence. Although active smokers have been reported to have twofold to threefold increased risk of suicidality when compared to nonsmokers, 1 4 research regarding the safest way to stop smoking does not always provide clear guidelines for practitioners wishing to advise their patients regarding smoking cessation strategies. In this article, we review pharmacological and cognitive behavioral therapy (CBT options that are available for people seeking to quit smoking, focusing on the relationship between the ability of these therapies to reduce smoking behavior and promote abstinence and suicidality risks as assessed by reported suicidality on validated measures, reports of suicidal ideation, behaviors, actual attempts, or completed suicides. Pharmacotherapies such as varenicline, bupropion, and nicotine replacement, and CBTs, including contextual CBT interventions, have been found to help reduce smoking rates and promote and maintain abstinence. Suicidality risks, while present when trying to quit smoking, do not appear to demonstrate a consistent or significant rise associated with use of any particular smoking cessation pharmacotherapy or CBT/contextual CBT intervention reviewed.

Becoming a smoker usually starts during adolescence and is a dynamic process involving experimentation before the establishment of daily smoking. It has been suggested that adolescents who smoke differ from those who do not in their attitudes to smoking. The purpose of this study was to find out whether attitudes related to smoking legislation and restrictions, social pressures in smoking and image of smokers are associated with smoking experimentation, daily smoking and best friends' smoking. The data were gathered with a self-administered questionnaire in North Karelia, Eastern Finland and in the Pitkyaranta district, Republic of Karelia, Russia. The respondents were 15-year-old 9th grade pupils in local schools. In Pitkyaranta, the data analyses covered pupils in all eight schools in the area (n = 179). In North Karelia, the data analyses comprised of selected eight schools (n = 601). Data were analysed with exploratory factor analysis. The models revealed that attitudes related to restrictions and social pressure were significantly associated with experimenting with smoking [OR (95 % CI) 7.923 (5.787-10.847)], daily smoking [OR (95 % CI) 9.575 (6.727-13.628)] and the likelihood of best friends' smoking [OR (95 % CI) 3.154 (2.579-3.858)]. The stronger the young peoples' attitudes and opinions, for example, towards restrictions and with more difficulties in refusing smoking, the higher the likelihood for smoking experimentations, daily smoking as well as the likelihood for their best friends' smoking. The country and factor interactions were not associated with smoking experimentations, daily smoking or best friends' smoking. Regardless of cultural background, adolescents who smoke have more positive attitudes to smoking, and perceive more social support for smoking, than do adolescents who do not smoke. The study stresses the similarity of the results in both Karelia's despite the enormous differences in culture, economy and public policy.

The second factor had been getting fear of sick and third family pressure.The most people had been quit smoking due to diseases of respiratory system. The most fearful disease was cancer. Financial status was forth effective factor on quitting smoking. Conclusion: As a result effective factors on unassisted smoking cessation had been getting fear of sick as well as own disease. Therefore, in the process of quitting smoking, and especially young people in the project will be designed to prevent smoking was thought should be given to these issues. Also important in this regard is increasing the cigarette sales price. The compliance with laws issued to prevent smoking in closed areas, in particular young people can influence their thoughts about the hazards of smoking.

Smoke-free air policies: past, present and future.

Science.gov (United States)

Hyland, Andrew; Barnoya, Joaquin; Corral, Juan E

2012-03-01

Smoke-free policies have been an important tobacco control intervention. As recently as 20 years ago, few communities required workplaces and hospitality venues to be smoke-free, but today approximately 11% of the world's population live in countries with laws that require these places to be smoke-free. This paper briefly summarises important milestones in the history of indoor smoke-free policies, the role of scientific research in facilitating their adoption, a framework for smoke-free policy evaluation and industry efforts to undermine regulations. At present, smoke-free policies centre on workplaces, restaurants and pubs. In addition, many jurisdictions are now beginning to implement policies in outdoor areas and in shared multiunit housing settings. The future of smoke-free policy development depends on credible scientific data that documents the health risks of secondhand smoke exposure. Over the next 20 years smoke-free policies will very likely extend to outdoor and private areas, and changes in the types of tobacco products that are consumed may also have implications for the nature and scope of the smoke-free policies of the future.

We explored the role of rejection of parental smoking in the association between parental smoking and smoking in adolescents. In 2010-11 cross-sectional survey, 61,810 Hong Kong secondary school students (mean age 14.6 years, 50.5% boys) reported their smoking (never, not susceptible; never, susceptible; ever, not current; current), paternal and maternal smoking, and whether they accepted paternal and maternal smoking (acceptance/rejection). We used multinomial logistic regression to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) of students' smoking in relation to acceptance and rejection of parental smoking, compared with no parental smoking. The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of paternal smoking was 1.81 (1.67-1.96), 2.46 (2.25-2.69), and 2.79 (2.51-3.10), respectively. The corresponding ORs for rejection were 0.70 (0.64-0.76), 1.23 (1.13-1.35), and 0.47 (0.40-0.56). The OR (95% CI) of "never, susceptible", "ever, not current", and "current", compared with "never, not susceptible", in relation to acceptance of maternal smoking was 2.05 (1.80-2.33), 2.57 (2.29-2.88), and 6.33 (5.39-7.44), respectively. The corresponding ORs for rejection were 0.85 (0.69-1.05), 1.59 (1.39-1.81), and 2.14 (1.71-2.68). No overlapping was observed between the 95% CIs for acceptance and rejection of paternal or maternal smoking. While adolescent smoking was associated with parental smoking, especially in those who accepted parental smoking, the association was attenuated or reversed in those who rejected parental smoking.

Smoking among American adults fell by half between 1950 and 2002, yet smoking on U.S. movie screens reached historic heights in 2002, topping levels observed a half century earlier. Tobacco’s comeback in movies has serious public health implications, because smoking on screen stimulates adolescents to start smoking,2,3 accounting for an estimated 52% of adolescent smoking initiation. Equally important, researchers have observed a dose-response relationship between teens’ exposure to ...

Background The National Cancer Institute has concluded that exposure to smoking in movies causes adolescent smoking and there are similar results for young adults. Purpose This study investigated whether exposure of young adult smokers to images of smoking in films stimulated smoking behavior. Methods 100 cigarette smokers aged 18–25 years were randomly assigned to watch a movie montage composed with or without smoking scenes and paraphernalia followed by a10-minute recess. The outcome was whether or not participants smoked during the recess. Data were collected and analyzed in 2008 and 2009. Results Smokers who watched the smoking scenes were more likely to smoke during the break (OR3.06, 95% CI=1.01, 9.29). In addition to this acute effect of exposure, smokers who had seen more smoking in movies before the day of the experiment were more likely to smoke during the break (OR 6.73; 1.00–45.25 comparing the top to bottom percentiles of exposure) were more likely to smoke during the break. Level of nicotine dependence (OR 1.71; 1.27–2.32 per point on the FTND scale), “contemplation” (OR 9.07; 1.71–47.99) and “precontemplation” (OR 7.30; 1.39–38.36) stages of change, and impulsivity (OR 1.21; 1.03–1.43), were also associated with smoking during the break. Participants who watched the montage with smoking scenes and those with a higher level of nicotine dependence were also more likely to have smoked within 30 minutes after the study. Conclusions There is a direct link between viewing smoking scenes and immediate subsequent smoking behavior. This finding suggests that individuals attempting to limit or quit smoking should be advised to refrain from or reduce their exposure to movies that contain smoking. PMID:20307802

The objective of this study was to measure secondhand smoke (SHS) exposure in personal computer (PC) rooms with the purpose of determining the strength of scientific evidence supporting the legislative ban on smoking in PC rooms located in the Republic of Korea. From June to September 2012, particulate matter (PM2.5) and air nicotine concentration (ANC) were measured in the smoking and non-smoking areas of PC rooms in Goyang City, Korea. In 28 randomly sampled PC rooms, field investigators completed an observational questionnaire on building characteristics, smoking policies, and evidence of smoking. The geometric means (GM) of PM2.5 and ANC in smoking and non-smoking areas were compared. Evidence of smoking was identified in both the smoking and non-smoking areas of all PC rooms. The GMs of PM2.5 and ANC in both areas were high and did not differ significantly (174.77 μg/m(3) and 48.95 μg/m(3) in smoking areas; 93.38 μg/m(3) and 41.30 μg/m(3) in non-smoking areas). Overall PM2.5 concentrations were 5.5-fold higher than those listed in the World Health Organization guidelines. This study supported previous reports that a partial smoking ban did not protect individuals from SHS exposure. Furthermore, the results from our study suggest how research can support policy. Countries in which smoke-free policies are not yet comprehensive may find our results useful.

Full Text Available Alicia Marín Armero,1 Miguel A Calleja Hernandez,2 Sabina Perez-Vicente,3 Fernando Martinez-Martinez4 1Community Pharmacy, Murcia, Spain; 2Hospital Pharmacy, University Hospital Virgen de las Nieves, Granada, Spain; 3Result Evaluation Unit, Institute of Biomedicine, Sevilla, Spain; 4Research Unit in Pharmaceutical Care, University of Granada, Granada, Spain Abstract: As a determining factor in various diseases and the leading known cause of preventable mortality and morbidity, tobacco use is the number one public health problem in developed countries. Facing this health problem requires authorities and health professionals to promote, via specific programs, health campaigns that improve patients’ access to smoking cessation services. Pharmaceutical care has a number of specific characteristics that enable the pharmacist, as a health professional, to play an active role in dealing with smoking and deliver positive smoking cessation interventions. The objectives of the study were to assess the efficacy of a smoking cessation campaign carried out at a pharmaceutical care center and to evaluate the effects of pharmaceutical care on patients who decide to try to stop smoking. The methodology was an open, analytical, pre–post intervention, quasi-experimental clinical study performed with one patient cohort. The results of the study were that the promotional campaign for the smoking cessation program increased the number of patients from one to 22, and after 12 months into the study, 43.48% of the total number of patients achieved total smoking cessation. We can conclude that advertising of a smoking cessation program in a pharmacy increases the number of patients who use the pharmacy’s smoking cessation services, and pharmaceutical care is an effective means of achieving smoking cessation.

Evidence shows that smoking is a major cause of cancer, and cancer patients who continue smoking are at greater risk for all causes of mortality, cancer recurrence, and second primary cancers. Nevertheless, many cancer patients still smoke and are not willing to quit. This study aimed at understanding the needs and concerns of current and ex-smoking cancer patients, including their risk perceptions, and the behavior and attitudes related to smoking. A qualitative research was conducted in an oncology outpatient clinic. A one-to-one semi-structured interview was conducted with current Chinese smokers and ex-smokers after they had been diagnosed with cancer. Data saturation was achieved after interviewing a total of 20 current smokers and 20 ex-smokers. A total of 241 patients who were smokers prior to their diagnosis of cancer were identified. Of 241 patients, 208 (86.31%) quitted and 33 (13.69%) continued smoking after receiving a cancer diagnosis. In general, patients who refused to quit smoking subsequent to a cancer diagnosis thought that the perceived barriers to quitting outweighed the perceived benefits of quitting. In contrast, most cancer patients who quit after their cancer diagnoses thought that the perceived benefits of quitting greatly outweighed the perceived barriers to quitting. It is vital that healthcare professionals should help cancer patients to quit smoking. Understanding how current smokers and ex-smokers perceive the risks of smoking, and their behavior, attitudes, and experiences related to smoking is an essential prerequisite for the design of an effective smoking cessation intervention.

Besides exercise intolerance, the assessment of ventilatory and perfusion adequacy allows additional insights in the disease pathophysiology in many cardiovascular or pulmonary diseases. Valid measurements of dead space/tidal volume ratios (VD/VT), arterial (a') - end-tidal (et) carbon dioxide (CO2) and oxygen (O2) pressure differences (p(a'-et)CO2) and (p(et-a')O2), and alveolar (A)-a' O2 pressure differences (p(A-a')O2) require using blood samples in addition to gas exchange analyses on a breath-by-breath-basis. Smoking and nutritional status are also important factors in defining disorders. Using a large healthy population we considered the impact of these factors to develop useful prediction equations. Incremental cycle exercise protocols were applied to apparently healthy volunteer adults who did not have structural heart disease or echocardiographic or lung function pathologies. Age, height, weight, and smoking were analysed for their influence on the target parameters in each gender. Reference values were determined by regression analyses. The final study sample consisted of 476 volunteers (190 female), aged 25-85 years. Smoking significantly influences p(A-a')O2 and p(a'-et)CO2 at rest and peak exercise, and VD/VT during exercise. Obesity influences upper limits of VD/VT, p(a'-et)CO2 and p(et-a')O2 at rest as well as p(A-a')O2 and p(et-a')O2 at exercise. Reference equations for never-smokers as well as for apparently healthy smokers considering influencing factors are given. Gender, age, height, weight, and smoking significantly influence gas exchange. Considering all of these factors this study provides a comprehensive set of reference equations derived from a large number of participants of a population-based study. Copyright © 2013 Elsevier Ltd.

Increasing numbers of technical and consumer products incorporating radioactive material are becoming available to the Australian public. One consumer device of this type coming into common use is the domestic smoke detector that uses Americium 241 in detecting smoke. This device has obvious life-saving and property-saving advantages and is attractive in that it is attractive in that it is self-contained, battery powered and needs little maintenance. The National Health and Medical Research Council in October 1978 recommended conditions, which are listed, are intended to ensure that radiation safety is preserved. They provide for the testing and approval of all models of domestic smoke detectors using radioactive material. The National Health and Medical Research Council stated that provided these conditions are applied it had no objection to the sale of these detectors by retailers

Full Text Available Introduction. The quality of our life is determined by the quality of the air that we breathe. Hence the influence of cigarette smoking and secondary exposure of persons within the smoking environment is significant. Previous studies have confirmed the influence of passive smoking to on the accumulation of given elements in the tonsils. The subject of the study is to determine the importance of ETS exposure for the accumulation of Pb, Be, Ba, Ca, Mg and Sr in the pharyngeal tonsils. Material and methods. The study involved 162 adenoids from boys and girls living in Tychy and Chorzów. exposed and not exposed to passive smoking. All biological samples were subjected to mineralization with nitric acid (V from Merck. The chemical composition of the samples was determined by the ICP – AES method. Results. The statistical analysis of the elements in the tonsils of children exposed and not exposed to ETS is performed taking into account as an additional criterion of distribution the place of residence and gender of the children. Conclusions. There was no significant effect of passive smoking on the increase of the examined metals in the adenoid. However the role of gender and place of residence to the process of accumulation of elements in this organ remains significant.

Previous research has demonstrated that cigarette smoke contains bacterial and fungal components including lipopolysaccharide (LPS) and ergosterol. In the present study we used gas chromatography–mass spectrometry to analyze tobacco as well as mainstream and second hand smoke for 3-hydroxy fatty acids (3-OH FAs) of 10 to 18 carbon chain lengths, used as LPS markers, and ergosterol, used as a marker of fungal biomass. The air concentrations of LPS were 0.0017 nmol/m 3 (N = 5) and 0.0007/m 3 (N = 6) in the smoking vs. non-smoking rooms (p = 0.0559) of the studied private houses, and 0.0231 nmol/m 3 (N = 5) vs. 0.0006 nmol/m 3 (N = 5) (p = 0.0173), respectively, at the worksite. The air concentrations of ergosterol were also significantly higher in rooms with ongoing smoking than in rooms without smoking. A positive correlation was found between LPS and ergosterol in rooms with smoking but not in rooms without smoking. 3-OH C14:0 was the main 3-OH FA, followed by 3-OH C12:0, both in mainstream and second hand smoke and in phenol:water smoke extracts prepared in order to purify the LPS. The Limulus activity of the phenolic phase of tobacco was 3900 endotoxin units (EU)/cigarette; the corresponding amount of the smoke, collected on filters from 8 puffs, was 4 EU/cigarette. Tobacco smoking has been associated with a range of inflammatory airway conditions including COPD, asthma, bronchitis, alveolar hypersensitivity etc. Significant levels of LPS and ergosterol were identified in tobacco smoke and these observations support the hypothesis that microbial components of tobacco smoke contribute to inflammation and airway disease. -- Highlights: ► Air concentration of bacterial and fungal markers is significantly higher in rooms with ongoing smoking than without smoking. ► Bacterial LPS correlates with fungal marker in rooms with ongoing smoking but not without smoking. ► LPS from mainstream smoke contains 3-hydroxy 14:0 and 12:0 fatty acids in similar proportion as

Pancreatitis, a debilitating inflammatory disorder, results from pancreatic injury. Alcohol abuse is the foremost cause, although cigarette smoking has recently surfaced as a distinct risk factor. The mechanisms by which cigarette smoke and its toxins initiate pathological cellular events leading to pancreatitis, have not been clearly defined. Although cigarette smoke is composed of more than 4000 compounds, it is mainly nicotine and the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), which have been extensively studied with respect to pancreatic diseases. This review summarizes these research findings and highlights cellular pathways which may be of relevance in initiation and progression of smoking-related pancreatitis.

Tobacco smoking is the most known single factor of the highest impact on the number of cancerous deceases. Chemical compound contained in the tobacco smoke have an affect on strong mutagen and carcinogenic actions. Among 400 chemical compound 40 of them have a proven carcinogenic action for human. From the medical point of view the most important are: nicotine- responsible as well as for the pharmacologic tobacco smoking addiction, carbon monoxide, carcinogenic and irritant substances. Regular monitoring of the tobacco smoking among academic students might be used in the actions considering the health risk management. The aim of the study was identifying the relation among selected socio-demographic factors like: age, sex, major, permanent residence, parent's education, material status, medical profile and tobacco smoking among academic students. The research was carried out among 521: science, humanities and medical stationary students. The research was conducted with a usage of the chi-squared evenness test. The research shows that sex and place of residence are the two factors having the most impact on tobacco smoking among academic students. Academic students originated from town or cities as well as men are more often to make a decision on smoking tobacco.

Tobacco smoking is common among various social groups. There is still high prevalence of smoking among health care professionals. The aim of the study was to assess knowledge about smoke-free law in public places in Poland among smoking and nonsmoking students of selected medical university. We surveyed 50 students of one medical university aged 23 +/- 2 years. Control group consisted with 61 students of other universities located in the same region aged 23 +/- 3 years. We developed a new survey to assess students knowledge about smoke-free regulations and their implementations in various public places. Smoking status was verified with exhaled carbon monoxide levels (COex). 57% off all surveyed students declared being familiar with smoke-free law. However, we detected a significant difference between the knowledge of medical vs. nonmedical students (76% vs. 41%, p < 0.05). The knowledge about smoke-free law in Poland among students is not sufficient, especially among nonmedical students.

Cigarette Taxes, Smoking-and Exercise?

Science.gov (United States)

Conway, Karen Smith; Niles, David P

2017-08-01

This research provides the first in-depth analysis of the effect that increased cigarette taxes have on exercise behavior. Smoking may diminish the ability to exercise; individuals may also use exercise to compensate for the harmful health effects of smoking or to avoid gaining weight if they cut back. Our conceptual model highlights these and several other avenues for effect and reveals that the predicted effect of cigarette costs on exercise behavior is theoretically ambiguous. To investigate the relationship empirically, 1994-2012 data from the behavioral risk factor surveillance system are combined with state level cigarette tax rates and other state level variables. Several measures of both smoking and exercise behavior are created and estimated in reduced form models. Our results suggest that both smoking and exercise are reduced by cigarette taxes. However, the effects on exercise may be more complicated as we find that certain groups, such as young adults or those who have recently quit smoking, are affected differently. Our analyses also show that the responsiveness of both smoking and exercise behavior to cigarette costs is much smaller in the 2000s, an era of high-tax increases.

Hostility has emerged as an important predictor of smoking cessation difficulties, though the mechanisms underlying the hostility and smoking relationship are poorly understood. Further, research has yet to explore relations between hostile interpretation biases and different aspects of smoking behavior. In the present study, current daily smokers (N = 106) were administered measures of smoking characteristics, smoking motivation, reasons for quitting, hostility, and hostile interpretation bias. Neither trait hostility nor hostile interpretation bias were uniquely associated with motivation to quit, reasons for quitting, nicotine dependence, or problematic symptoms following past cessation attempts. However, hostility and hostile interpretation biases were uniquely associated with different reasons for smoking. Additionally, greater hostile interpretation bias (but not hostility) was uniquely associated with early relapse following past cessation attempts. The current findings add uniquely to the growing, but still relatively small, literature on hostility and smoking and implicate hostile interpretation bias as a potential treatment target in smoking cessation interventions.

Does it matter what friends think, say, or do? The role of friends' smoking attitudes and behavior for Dutch adolescents' smoking behavior.

Science.gov (United States)

Huisman, Chip

2014-05-01

Using stochastic actor-based models for longitudinal network analysis, this study examines the role of friends' smoking attitudes and behavior for Dutch adolescents' smoking behavior in four secondary schools (N = 875). The data were collected in two waves in two small suburban towns under second graders in 2008 to 2009 by means of a standardized questionnaire. Stochastic actor-based models for longitudinal network analysis can control for friendship selection while examining the effect of friends' attitudes and smoking behavior on the smoking behavior of a student. The findings suggest that friends tend to select each other on similar smoking behavior. Influence of friends' smoking behavior seems to play no role. In one school, an effect of friends' attitudes towards smoking on the smoking behavior is found. The implications for future research are to consider attitudes when examining the influence of friendship network on smoking behavior. The main limitation of this study lies in the limited sample, which makes generalizations to the general population difficult.

What factors influence smoking prevalence and smoke free policy enactment across the European Union Member States.

Directory of Open Access Journals (Sweden)

Ilze Bogdanovica

Full Text Available BACKGROUND: Smoking prevention should be a primary public health priority for all governments, and effective preventive policies have been identified for decades. The heterogeneity of smoking prevalence between European Union (EU Member States therefore reflects, at least in part, a failure by governments to prioritise public health over tobacco industry or possibly other financial interests, and hence potentially government corruption. The aims of this study were to test the hypothesis that smoking prevalence is higher in countries with high levels of public sector corruption, and explore the ecological association between smoking prevalence and a range of other national characteristics in current EU Member States. METHODS: Ecological data from 27 EU Member States were used to estimate univariate and multivariate correlations between smoking prevalence and the Transparency International Corruption Perceptions Index, and a range of other national characteristics including economic development, social inclusion, quality of life and importance of religion. We also explored the association between the Corruption Perceptions Index and measures of the extent to which smoke-free policies have been enacted and are enforced. RESULTS: In univariate analysis, smoking prevalence was significantly higher in countries with higher scores for corruption, material deprivation, and gender inequality; and lower in countries with higher per capita Gross Domestic Product, social spending, life satisfaction and human development scores. In multivariate analysis, only the corruption perception index was independently related to smoking prevalence. Exposure to tobacco smoke in the workplace was also correlated with corruption, independently from smoking prevalence, but not with the measures of national smoke-free policy implementation. CONCLUSIONS: Corruption appears to be an important risk factor for failure of national tobacco control activity in EU countries, and

Reactive oxygen species (ROS) are of primary importance as they cause damage to lipids, proteins, and DNA either endogenously by cellular mechanism, or through exogenous exposure to environmental injury factors, including oxidation insult factors, such as tobacco smoke. Currently 46.3 million adults (25.7 percent of the population) are smokers. This includes 24 million men (28.1 percent of the total) and more than 22 million women (23.5 percent). The prevalence is highest among persons 25-44 years of age. Cigarette smokers have a higher risk of developing several chronic disorders. These include fatty buildups in arteries, several types of cancer and chronic obstructive pulmonary disease (lung problems). As peripheral leukocytes have been the main target of human telomere research, most of what is known about human telomere dynamics in vivo is based on these cells. Leukocyte telomere length (TL) is a complex trait that is shaped by genetic, epigenetic, and environmental determinants. In this article, we consider that smoking modifies leukocyte TL in humans and contributes to its variability among individuals, although the smoking effect on TL and its relation with other metabolic indices may accelerate biological aging and development of smoking-induced chronic diseases in a large human population-based cohorts with smoking behavior. Recent studies confirmed that individuals with shorter telomeres present a higher prevalence of arterial lesions and higher risk of cardiovascular disease mortality. This study originally suggests that efficient therapeutic protection of TL and structure in response to stresses that are known to reduce TL, such as oxidative damage or inflammation associated with tobacco smoking, would lead to better telomere maintenance. Recently, we have discovered the potential use of telomere-restorative imidazole-containing dipeptide (non-hydrolized carnosine, carcinine) based therapy for better survival of smokers. We conclude that a better

Few studies have investigated the complex interactions among the individual- and community-level social risk factors that underlie adolescents’ smoking behaviors. This study investigated whether community-level adult daily smoking prevalence is associated with adolescents’ smoking and whether it moderates the associations between perceived friends’ smoking approval and smoking behavior and adolescents’ own smoking. Self-reported data from 1,190 youths (50.3% female; 13–18 years old) in 50 midsized Californian cities were obtained through telephone interviews. Community characteristics were obtained from 2010 GeoLytics data. Community adult daily smoking prevalence was ascertained from telephone interviews with 8,918 adults conducted in the same 50 cities. Multilevel analyses, controlling for individual and city characteristics, were used to predict adolescents’ past 12-month smoking from perceived friends’ smoking approval and smoking behavior and from community adult daily smoking prevalence. Results showed that perceived friends’ smoking approval and behavior were associated positively with adolescents’ smoking, as was the community-level prevalence of adult daily smoking. Furthermore, the association between perceived friends’ smoking behavior and adolescents’ own smoking was moderated by the prevalence of adult daily smokers in the community. Specifically, the association was stronger in cities with higher prevalence of adult smokers. These results suggest that adult community norms that are more supportive of smoking may enhance the influence of friends’ smoking behavior. Therefore, interventions designed to prevent or reduce youths’ smoking should also focus on reducing smoking by adults. PMID:24241785

Intention to smoke is a valid and reliable factor for predicting future smoking habits among adolescents. This factor, however, has received inadequate attention in Malaysia. The present paper elaborates the prevalence and factors associated with intent to initiate or to cease smoking, among adolescent nonsmokers and smokers in Kota Tinggi, Johor, Malaysia. A total of 2,300 secondary school students aged 13-16 years were selected through a two-stage stratified sampling method. A set of standardized questionnaires was used to assess the smoking behavior among adolescents and the inter-personal and intra-personal factors associated with smoking intention (intention to initiate smoking or to cease smoking). Multivariable logistic regression was used to identify factors related to smoking intention. The prevalence of intention to smoke in the future or to cease smoking among non- smoking adolescents and current smokers were 10.7% and 61.7% respectively. Having friends who smoke, social influence, and poor knowledge about the ill effects on health due to smoking showed significant relationships with intention to smoke in the future among non-smokers. Conversely, perceived lower prevalence of smoking among peers, weak contributory social influence, and greater awareness of the ill effects of smoking are factors associated with the intention to cease smoking sometime in the future. The study found that prevalence of intention to initiate smoking is low among non-smokers while the majority of current smokers intended to cease smoking in the future. Existing anti-smoking programmes that integrate the factors that have been identified in the current study should be put in motion to reduce the prevalence of intention to initiate smoking and increase the intention to cease smoking among adolescents.

Full Text Available According to the research carried out by the authors the most technological installations for producing meat and fish products are oriented only on one type of raw material (meat or fish, as well as the kind of smoking (cold or hot. Limitations are related to the maximum temperature of the drying agent that affects the product; presence of the system for maintaining the relative humidity of the air mixture; presence of the smoke cooling system coming from the smoke generator and a number of other factors. Enterprises expanding the range of products are forced to purchase new equipment. With a limited production area especially for small businesses this is not convenient. In the paper, a universal smoking installation of the rotor type (USIRT is considered for the production of both meat and fish products using cold or hot smoking. The installation is oriented to a wide range of products. The presence of the smoke cooling system will allow the production of cold smoking products, the presence of the dehumidification and humidification system for the smoke-air mixture will ensure the maintenance of the required technological regime for producing fish and meat products. Based on the example of cold smoking studies have shown that the duration of the process should be reduced while maintaining the quality of the product. For this purpose, ultrasonic (US vibrations have been applied to the smoke-air mixture in USIRT. The studies have been carried out to identify the best type of ultrasound radiators capable of transmitting vibrations of the installation metal surface and from it to pass into the smoke-air mixture in order to intensify the process of cold smoking. The necessary power of ultrasonic generators has been determined. Comparative results of technological processes with the application of ultrasound in the production of fish products have been presented.

Black cigarette smokers have lower rates of smoking cessation compared with Whites. However, the mechanisms underlying these differences are not clear. Many Blacks live in communities saturated by tobacco advertisements. These cue-rich environments may undermine cessation attempts by provoking smoking. Moreover, attentional bias to smoking cues (attention capture by smoking cues) has been linked to lower cessation outcomes. Cessation attempts among Blacks may be compromised by attentional bias to smoking cues and a cue-rich environment. Attention to smoking cues in Black and White smokers was examined in 2 studies. In both studies, assessments were completed during 2 laboratory visits: a nonabstinent session and an abstinent session. In study 1, nontreatment-seeking smokers (99 Whites, 104 Blacks) completed the Subjective Attentional Bias Questionnaire (SABQ; a self-report measure of attention to cues) and the Smoking Stroop task (a reaction time measure of attentional bias to smoking cues). In study 2, 110 White and 74 Black treatment-seeking smokers completed these assessments and attempted to quit. In study 1, Blacks reported higher ratings than Whites on the SABQ (p = .005). In study 2, Blacks also reported higher ratings than Whites on the SABQ (p = .003). In study 2, Blacks had lower biochemical-verified point prevalence abstinence than Whites, and the between-race difference in outcome was partially mediated by SABQ ratings. Blacks reported greater attention to smoking cues than Whites, possibly due to between-race differences in environments. Greater attention to smoking cues may undermine cessation attempts. © The Author 2015. Published by Oxford University Press on behalf of the Society for Research on Nicotine and Tobacco.

2016-09-01

To explore the impact of interactions between smoking and symptoms of posttraumatic stress disorder (PTSD) on pain intensity, psychological distress, and pain-related functioning in patients with orofacial pain, a retrospective review was conducted of data obtained during evaluations of 610 new patients with a temporomandibular disorder who also reported a history of a traumatic event. Pain-related outcomes included measures of pain intensity, psychological distress, and pain-related functioning. Main effects of smoking status and PTSD symptom severity on pain-related outcomes were evaluated with linear regression analyses. Further analyses tested interactions between smoking status and PTSD symptom severity on pain-related outcomes. PTSD symptom severity and smoking predicted worse pain-related outcomes. Interaction analyses between PTSD symptom severity and smoking status revealed that smoking attenuated the impact of PTSD symptom severity on affective distress, although this effect was not found at high levels of PTSD symptom severity. No other significant interactions were found, but the present results identifying smoking as an ineffective coping mechanism and the likely role of inaccurate outcome expectancies support the importance of smoking cessation efforts in patients with orofacial pain. Smoking is a maladaptive mechanism for coping with pain that carries significant health- and pain-related risks while failing to fulfill smokers' expectations of affect regulation, particularly among persons with orofacial pain who also have high levels of PTSD symptom severity. Addressing smoking cessation is a critical component of comprehensive treatment. Further research is needed to develop more effective ways to help patients with pain and/or PTSD to replace smoking with more effective coping strategies. © International & American Associations for Dental Research 2016.

The effects of Smoke Free Work Hours in Danish municipalities

OpenAIRE

Tina Termansen; Simon Rask

2017-01-01

Since 2011, 15 Danish municipalities have implemented smoke free work hours, meaning that an employee working for the municipality may not smoke in his or her work time (about 7,5 hours a day). This is a much stricter prevention method, than former strategies preventing smoking mostly at locations and not during working hours. Research concerning the effects of smoke free work hours is non-existing. We therefore wish to look into the specific outcomes of smoke free work hours related to smoki...

The effects of marijuana smoke exposure on several measures of tobacco cigarette smoking behavior were examined. Eight healthy adult male volunteers, who smoked both tobacco and marijuana cigarettes, participated in residential studies, lasting 10 to 15 days, designed to measure the effects of marijuana smoke exposure on a range of behavioral variables. Tobacco cigarettes were available throughout the day (9:00 A.M. until midnight). Each day was divided into a private period (9:00 A.M. to 5:00 P.M.), during which subjects were socially isolated, and a social period (5:00 P.M. to midnight), during which subjects could interact. Under blind conditions, subjects smoked placebo and active marijuana cigarettes (0%, 1.3%, 2.3%, or 2.7% delta 9-tetrahydrocannabinol) four times daily (9:45 A.M., 1:30 P.M., 5:00 P.M. and 8:30 P.M.). Each subject was exposed to both placebo and one active dose over 2- to 5-consecutive-day intervals, and dose conditions (i.e., placebo or active) alternated throughout the study. Active marijuana smoking significantly decreased the number of daily tobacco smoking bouts, increased inter-bout intervals and decreased inter-puff intervals. Marijuana decreased the number of tobacco smoking bouts by delaying the initiation of tobacco cigarette smoking immediately after marijuana smoking, whereas decreases in inter-puff intervals were unrelated to the time of marijuana smoking. No consistent interactions between marijuana effects and social or private periods (i.e., time of day) were observed.

Detrimental effects of environmental tobacco smoke in relation to asthma severity.

Full Text Available Environmental tobacco smoke (ETS has adverse effects on the health of asthmatics, however the harmful consequences of ETS in relation to asthma severity are unknown.In a multicenter study of severe asthma, we assessed the impact of ETS exposure on morbidity, health care utilization and lung functions; and activity of systemic superoxide dismutase (SOD, a potential oxidative target of ETS that is negatively associated with asthma severity.From 2002-2006, 654 asthmatics (non-severe 366, severe 288 were enrolled, among whom 109 non-severe and 67 severe asthmatics were routinely exposed to ETS as ascertained by history and validated by urine cotinine levels. ETS-exposure was associated with lower quality of life scores; greater rescue inhaler use; lower lung function; greater bronchodilator responsiveness; and greater risk for emergency room visits, hospitalization and intensive care unit admission. ETS-exposure was associated with lower levels of serum SOD activity, particularly in asthmatic women of African heritage.ETS-exposure of asthmatic individuals is associated with worse lung function, higher acuity of exacerbations, more health care utilization, and greater bronchial hyperreactivity. The association of diminished systemic SOD activity to ETS exposure provides for the first time a specific oxidant mechanism by which ETS may adversely affect patients with asthma.

Overcoming Limitations in Previous Research on Exercise as a Smoking Cessation Treatment: Rationale and Design of the “Quit for Health” Trial

Williams, David M.; Ussher, Michael; Dunsiger, Shira; Miranda, Robert; Gwaltney, Chad J.; Monti, Peter M.; Emerson, Jessica

2013-01-01

Aerobic exercise has been proposed as a stand-alone or adjunct smoking cessation treatment, but findings have been mixed. Laboratory studies have shown that individual exercise sessions lead to decreases in withdrawal symptoms and cigarette cravings, but findings are limited by lack of follow-up and artificial settings. On the other hand, smoking cessation treatment RCTs have generally failed to show positive effects of exercise on smoking cessation, but have been plagued by poor and/or unverified compliance with exercise programs. This paper describes the rationale and design for Quit for Health (QFH)—an RCT designed to determine the efficacy of aerobic exercise as an adjunct smoking cessation treatment among women. To overcome limitations of previous research, compliance with the exercise (and wellness contact control) program is incentivized and directly observed, and ecological momentary assessment is used to examine change over time in withdrawal symptoms and cigarette cravings in participants’ natural environments.

To find out the smoking status among the families and their members, in order to hold their knowledge, attitude, practice on smoking and its influence and to put forward the countermeasure of smoking Control. A questionnaire surveys were conducted among 419 people which came from 419 families. 409 qualified questionnaire were obtained. The data were analyzed by descriptive statistics, test and logistic analysis. The family current smoking rates were 68.2%, the smoking rates of past family were 90.2%, the current smoking rates of individual were 31.5%, the individual past smoking rates were 39.9%. Those who attempted smoking under the age of 18 years accounted for 46.6%. Those who smoked their first cigarette from friends accounted for 48.1%. The comparisons of knowledge, attitude between smoking-ever family members and non-smoking family members had significant difference (P attitude between smoking family members and non-smoking family members had significant difference (P < 0.05). Those who were married women, and had career had high score of KAP. The contents of education of the decreases of smoking rates were on the following: (1) Smoking damages health. (2) Smoking should not be used as means of communication. (3) Feel offensive when someone smoking around. (4) Most persons still don't smoke. The key place of smoking control could be family. Smoking control could depend on married female. The key crowd of tobacco control could be children and youngsters. Not offering smoke and not advise others to smoking could be the key measures of smoking control.

Although public smoking restrictions have been implemented, children are still exposed to household smoking. Parental smoking is the main source of children's exposure to secondhand smoke. This study was conducted to examine the factors associated with parents' adoption of home smoking bans. A cross-sectional study was conducted using a self-administered questionnaire to collect data from 768 parents of school-aged children in Taiwan. The home smoking restriction status, parents' perceptions of smoking in the presence of children and its influences, and parents' sociodemographic characteristics were assessed. Hierarchical logistic regression analysis was used to determine the best-fit model. More than 80% of the parents agreed with home smoking bans, whereas only approximately 26% of the parents actually restricted smoking at home completely. The crude odds ratios showed that parents who perceived the influence of parental smoking on children to be negative were more likely to adopt home smoking bans. Hierarchical logistic regression revealed factors associated with the adoption of home smoking bans, including a higher education level and older age of parents, a family composed of nonparent adults, and opposition to parental smoking in the presence of children. Children's health is a major concern for parents considering home smoking bans. Helping parents clarify misunderstandings regarding parental smoking, emphasizing the adverse effects of children's exposure to parental smoking, suggesting healthy substitutes for smoking, and providing effective strategies for maintaining a smoke-free home can motivate families to adopt home smoking bans. © The Author 2014.

One of the most severe detrimental environmental factors acting during pregnancy is foetal smoke exposure. The aim of this study was to assess the effect of maternal, paternal and parental smoking during pregnancy on relative leg length in 7- to 10-year-old children. The research conducted in the years 2001-2002 included 978 term-born children, 348 boys and 630 girls, at the age of 7-10 years. Information concerning the birth weight of a child was obtained from the health records of the women. Information about the mother's and the father's smoking habits during pregnancy and about the mothers' education level was obtained from a questionnaire. The influence of parental smoking on relative leg length, controlled for age, sex, birth weight and the mother's education, as a proxy measure of socioeconomic status, and controlled for an interaction between sex and birth weight, was assessed by an analysis of covariance, where relative leg length was the dependent variable, smoking and sex were the independent variables, and birth weight as well as the mother's education were the covariates. Three separate analyses were run for the three models of smoking habits during pregnancy: the mother's smoking, the father's smoking and both parents' smoking. Only both parents' smoking showed a significant effect on relative leg length of offspring. It is probable that foetal hypoxia caused by carbon monoxide contained in smoke decelerated the growth of the long bones of foetuses. Copyright © 2016 Elsevier GmbH. All rights reserved.

To explore whether parental behaviours related to smoking socialisation and parenting are associated with smoking susceptibility and current smoking in 14-15 year old students. Data were sourced from the New Zealand 2006 Year 10 In-depth Survey, a school-based survey of 3,189 students. Outcome measures were susceptibility to smoking and current smoking. Potential determinants were second-hand smoke exposure in the home, parental smoking, parental anti-smoking expectations, anti-smoking rules, pocket money, monitoring of pocket money expenditure, general rule setting and monitoring, and concern about education. Analysis used logistic regression to adjust for potential confounding factors. Exposure to second-hand smoke and lack of parental anti-smoking expectations were independently associated with smoking susceptibility and current smoking. Parental smoking was not independently associated with current smoking or susceptibility. Receiving pocket money and an absence of monitoring of expenditure were associated with smoking susceptibility and current smoking. Lack of parental rule setting was associated with smoking susceptibility. Findings were similar whether or not one or more parents were smokers. Not allowing smoking in the home, communicating non-smoking expectations to children, monitoring pocket money, and setting rules to guide behaviour are strategies which are likely to reduce risk of smoking uptake. The study provides evidence to inform the development of parent-focused interventions to reduce the risk of smoking initiation by children. © 2011 The Authors.

Speyer, Cameron B; Costenbader, Karen H

2018-06-01

Systemic lupus erythematosus (SLE) is a multi-system inflammatory autoimmune disease of incompletely understood etiology. It is thought that environmental exposures 'trigger' or accelerate the disease in genetically-predisposed individuals. Areas covered: Substantial epidemiological evidence exists to support the association between cigarette smoking and the risk of incident SLE. Recent evidence points to current smoking as the specific risk factor, with decreasing risk 5 years after smoking cessation, and the greatest risk for disease characterized by the presence of SLE-specific autoantibodies. Research has begun to search for possible explanations for the temporal nature of the relationship between current smoking and autoantibody positive-SLE. Here we review potential biologic mechanisms linking smoking and SLE risk, including effects upon T and B cells, inflammatory cytokines, oxidative stress, and the formation of short-lived DNA adducts. Expert commentary: The directions for future research in this field include studies of gene-environment interactions, epigenetics, metabolomics and putative biologic mechanisms.

This study investigates the independent and combined effects of smoking of parents and best friend on smoking and the intention to initiate or quit smoking in adolescents. In this school-based survey, 6,553 Hong Kong students aged 13-18 reported their demographic characteristics, smoking status of themselves, parents, and best friend; and intention to smoke (initiation among never-smokers and reinitiation among ex-smokers) or quit smoking among current smokers. Logistic regression yielded adjusted odds ratios (AORs) of student smoking (current/ever) and intention to smoke or quit smoking for parental (paternal/maternal/both parents vs. none) and best friend (yes vs. no) smoking. Parental smoking and having a smoking best friend were associated with adolescent current smoking, ever smoking, and intention to initiate smoking. Having a smoking best friend was also associated with reinitiating and quitting smoking. The AORs (95% CI) of current smoking for having a smoking best friend, in addition to smoking father, mother, or both were 19.14 (14.36-25.51), 20.38 (12.42-33.43), and 24.18 (15.89-36.77). The respective AORs of ever smoking were 8.30 (6.74-10.22), 8.92 (5.63-14.12), and 11.99 (8.05-17.87). Parental smoking and best friend smoking have independent effects on adolescent smoking behaviors. Their combined effects on current and ever smoking were particularly large. Smoking prevention programs should pay special attention to adolescents with both best friend and parents who smoke.

Full Text Available Marine and fisheries resources in Situbondo Regency were potential to supports seafood processing, e.g. traditional smoked processing of mackerel tuna (Euthynnus affinis Cantor based on local wisdom. This research was aimed to assess and analyzes: the processing of smoked mackerel tuna based on local wisdom, public perception towards the processing of smoked mackerel tuna, and the quality of smoked mackerel tuna. The research carried out on January to April 2014, in Jangkar Village, Situbondo regency. The study included depth interview from key persons with questionnaire and organoleptic test. The public perception on smoked mackerel tuna was taken by questionnaire from 85 respondents, whereas the quality of smoked mackerel tuna was analyzed with laboratory proximate test. Result of this research showed that smoked mackerel tuna processing used traditional smoking instrument and fuel material. The smoking stall used several banana midrib stem above the furnace that made of cement and bricks, while the fuel use coconut coir which created the typical flavors of the smoked mackerel tuna. The average organoleptic value of the smoked mackerel tuna appearance is 7.89 (intact, clean, brown, very shiny specific type, flavors of 8.24 (less fragrant, smoked enough, without additional disturbing odor, taste of 8.41 (delicious, savory, texture of 7.40 (solid, compact, fairly dry, tight inter-flesh tissue, and colour of 7.20 (attractive, specific, shiny brown colour type. Public perception showed that the community knowledge on smoked mackerel tuna processing is good, creates good flavors of smoked mackerel tuna and favored by the community, thus also encourage the community to support the conservation of this traditional smoked processing. Lab analysis showed that the proximate value of 0.99% carbohydrates, 29.59% protein, 1.14% fat, 2.89% mineral, 1.88% ash, and 63.4% water.

Environmental determinants of smoking behaviors: The role of policy and environmental interventions in preventing smoking initiation and supporting cessation.

Science.gov (United States)

Calo, William A; Krasny, Sarah E

2013-12-01

Tobacco control strategies have contributed to substantial declines in smoking in the United States. However, smoking still remains the single largest preventable cause of disease and premature deaths in the country. Despite the continuing challenges of implementing tobacco control strategies and the pervasive influence of the tobacco industry to undermine such strategies, there are now unprecedented opportunities to prevent smoking initiation, facilitate cessation, and protect nonsmokers from secondhand smoke. In this paper, we briefly review the most recent literature discussing key strategies that have proven effective in tobacco control including regulations on sales and marketing of tobacco products, taxation, and smoke-free legislation. We focused on these three tobacco control strategies because of their potential to positively influence the environment of both minors and adults regardless of their smoking status. Although research has identified significant individual and social predictors of tobacco use, environmental influences are also important risk factors for tobacco use.

To describe the Talking About The Smokes (TATS) project according to the World Health Organization guiding principles for conducting community-based participatory research (PR) involving indigenous peoples, to assist others planning large-scale PR projects. The TATS project was initiated in Australia in 2010 as part of the International Tobacco Control Policy Evaluation Project, and surveyed a representative sample of 2522 Aboriginal and Torres Strait Islander adults to assess the impact of tobacco control policies. The PR process of the TATS project, which aimed to build partnerships to create equitable conditions for knowledge production, was mapped and summarised onto a framework adapted from the WHO principles. Processes describing consultation and approval, partnerships and research agreements, communication, funding, ethics and consent, data and benefits of the research. The TATS project involved baseline and follow-up surveys conducted in 34 Aboriginal community-controlled health services and one Torres Strait community. Consistent with the WHO PR principles, the TATS project built on community priorities and strengths through strategic partnerships from project inception, and demonstrated the value of research agreements and trusting relationships to foster shared decision making, capacity building and a commitment to Indigenous data ownership. Community-based PR methodology, by definition, needs adaptation to local settings and priorities. The TATS project demonstrates that large-scale research can be participatory, with strong Indigenous community engagement and benefits.

Smoking and attitudes toward smoking policy at a University in Egypt.

2016-01-01

To assess smoking behavior, knowledge of smoking harm, and attitudes toward campus smoking policy at an Egyptian university, an online survey of students, staff, and faculty was conducted (N = 992). The smoking prevalence of 38% among men was in line with Egypt's national average, but the smoking prevalence among women of 20% was much higher than the national average. Smoking status influenced beliefs about smoking harm and attitudes toward smoking policy, with nonsmokers having stronger beliefs about the harm of smoking and showing stronger support for smoking regulations than smokers. Smokers were more knowledgeable about smoking policy than were nonsmokers and differed slightly in their preferences for smoking policy enforcement strategies. These findings contribute to our understanding of how to tailor college smoking policy and programs to an Egyptian context.

The study objectives were to determine the effects of smoking machine puffing parameters on mainstream smoke composition and to express those effects as predicting relationships. Forty-eight commercial Philip Morris USA and Philip Morris International cigarettes from international markets and the 1R4F reference cigarette were machine-smoked using smoking conditions defined by the International Organization of Standardization (ISO), the Massachusetts Department of Public Health (MDPH), and Health Canada (HC). Cigarette tobacco fillers were analyzed for nitrate, nicotine, tobacco-specific nitrosamines (TSNA), and ammonia. Mainstream yields for tar and 44 individual smoke constituents and "smoke pH" were determined. Cigarette constituent yields typically increased in the order ISOrelationships were developed between ISO tar and ISO, MDPH, and HC constituent yields and between MDPH tar and HC tar and respective smoking condition yields. MDPH and HC constituent yields could be predicted with similar reliability using ISO tar or the corresponding smoking-condition tar. The reliability of the relationships varied from strong to weak, depending on particular constituents. Weak predicting relationships for nitrogen oxides and TSNA's, for example, were improved with inclusion of tobacco filler composition factors. "Smoke pH" was similar for all cigarettes at any one smoking condition, and overall marginally lower at HC conditions than at ISO or MDPH conditions.

Smoking in film is a risk factor for smoking uptake in adolescence. This study aimed to quantify exposure to smoking in film received by New Zealand audiences, and evaluate potential interventions to reduce the quantity and impact of this exposure. The ten highest-grossing films in New Zealand for 2003 were each analysed independently by two viewers for smoking, smoking references and related imagery.

Seven of the ten films contained at least one tobacco reference, similar to larger film samples. The majority of the 38 tobacco references involved characters smoking, most of whom were male.

Full Text Available Abstract Background Smoking in film is a risk factor for smoking uptake in adolescence. This study aimed to quantify exposure to smoking in film received by New Zealand audiences, and evaluate potential interventions to reduce the quantity and impact of this exposure. Methods The ten highest-grossing films in New Zealand for 2003 were each analysed independently by two viewers for smoking, smoking references and related imagery. Potential interventions were explored by reviewing relevant New Zealand legislation, and scientific literature. Results Seven of the ten films contained at least one tobacco reference, similar to larger film samples. The majority of the 38 tobacco references involved characters smoking, most of whom were male. Smoking was associated with positive character traits, notably rebellion (which may appeal to adolescents. There appeared to be a low threshold for including smoking in film. Legislative or censorship approaches to smoking in film are currently unlikely to succeed. Anti-smoking advertising before films has promise, but experimental research is required to demonstrate cost effectiveness. Conclusion Smoking in film warrants concern from public health advocates. In New Zealand, pre-film anti-smoking advertising appears to be the most promising immediate policy response.

Tobacco smoking is the cause of many preventable diseases and premature deaths in the UK and around the world. It poses enormous health- and non-health-related costs to the affected individuals, employers, and the society at large. The World Health Organization (WHO) estimates that, globally, smoking causes over US$500 billion in economic damage each year. This paper examines global and UK evidence on the economic impact of smoking prevalence and evaluates the effectiveness and cost effectiveness of smoking cessation measures. SEARCH METHODS We used two major health care/economic research databases, namely PubMed and the National Institute for Health Research (NIHR) database that contains the British National Health Service (NHS) Economic Evaluation Database; Cochrane Library of systematic reviews in health care and health policy; and other health-care-related bibliographic sources. We also performed hand searching of relevant articles, health reports, and white papers issued by government bodies, international health organizations, and health intervention campaign agencies. SELECTION CRITERIA The paper includes cost-effectiveness studies from medical journals, health reports, and white papers published between 1992 and July 2014, but included only eight relevant studies before 1992. Most of the papers reviewed reported outcomes on smoking prevalence, as well as the direct and indirect costs of smoking and the costs and benefits of smoking cessation interventions. We excluded papers that merely described the effectiveness of an intervention without including economic or cost considerations. We also excluded papers that combine smoking cessation with the reduction in the risk of other diseases. DATA COLLECTION AND ANALYSIS The included studies were assessed against criteria indicated in the Cochrane Reviewers Handbook version 5.0.0. OUTCOMES ASSESSED IN THE REVIEWPrimary outcomes of the selected studies are smoking prevalence, direct and indirect costs of smoking

The association between some factors of the familial and social environment with smoking in non-student adolescents with asthma has not been explored. The aim of the study was to determine the association between family structure, educational level, parental approval of smoking, parents who smoke, and smoking friends with smoking in non-student adolescents with asthma. In a cross-sectional study, data were obtained by means of a structured questionnaire applied to 4,778 non-student adolescents aged 13-18 years. Diagnosis of asthma was performed using a questionnaire based on the International Study of Asthma and Allergy in Childhood questionnaire. The smoking habit was determined by application of a self-administered questionnaire. Odds ratios (OR) were determined for smoking using logistic regression. From the total sample, asthma prevalence was 6.6% and of active smoking, 34.2%. Age at initiation of asthma symptoms was 5.15±3.52 years, and that of active smoking was 13.65±2.07 years. Percentage of non-intact family (40.1 vs. 32.7%) was greater in the group of adolescents with asthma. Logistic regression models show that parental approval of smoking (adjusted OR=5.57; 95% confidence interval=2.48-12.51) and smoking friends (adjusted OR=2.92; 95% confidence interval=1.04-8.19) are associated with smoking in non-student adolescents with asthma. In this study, parental approval of smoking and having friends who smoke appear to be associated with smoking among non-student adolescents with asthma. Copyright © 2011 SEPAR.

Research has shown that smokers have an attentional bias for pictorial smoking cues. The objective of the present study was to examine whether smokers also have an attentional bias for dynamic smoking cues in contemporary movies and therefore fixate more quickly, more often and for longer periods of time on dynamic smoking cues than non-smokers. By drawing upon established methods for assessing attentional biases for pictorial cues, we aimed to develop a new method for assessing attentional biases for dynamic smoking cues. We examined smokers' and non-smokers' eye movements while watching a movie clip by using eye-tracking technology. The sample consisted of 16 smoking and 17 non-smoking university students. Our results confirm the results of traditional pictorial attentional bias research. Smokers initially directed their gaze more quickly towards smoking-related cues (p = 0.01), focusing on them more often (p = 0.05) and for a longer duration (p = 0.01) compared with non-smokers. Thus, smoking cues in movies directly affect the attention of smokers. These findings indicate that the effects of dynamic smoking cues, in addition to other environmental smoking cues, need to be taken into account in smoking cessation therapies in order to increase successful smoking cessation and to prevent relapses.

Full Text Available Sickle cell disease (SCD is an autosomal recessive hemoglobinopathy that causes significant morbidity and mortality related to chronic hemolytic anemia, vaso-occlusion, and resultant end-organ damage. Tobacco smoke exposure (TSE through secondhand smoke exposure in people with SCD of all ages and through primary smoking in adolescents and adults is associated with significantly increased morbidity, with increased rates of emergency department visits and hospitalizations for painful vaso-occlusive crises and acute chest syndrome (ACS. Secondhand smoke is also associated with pulmonary function abnormalities in children with SCD who are already at risk for pulmonary function abnormalities on the basis of SCD. TSE is emerging as one of the few modifiable risk factors of SCD. This review discusses the current state of the evidence with respect to TSE and SCD morbidity, discusses potential mechanisms, and highlights current gaps in the evidence and future research directions.
