Trend over time on knowledge of the health effects of cigarette smoking and smokeless tobacco use in Bangladesh: Findings from the International Tobacco Control Policy Evaluation Bangladesh Surveys.

Cigarette smoking and smokeless tobacco (ST) use are prevalent in Bangladesh. This longitudinal study examined how knowledge of the health effects of smoking and ST use in Bangladesh has changed overtime with the country's acceleration of tobacco control efforts. Data were analysed from the International Tobacco Control Survey, a nationally representative longitudinal study of users and non-users of tobacco (aged 15 and older) in Bangladesh, across four waves conducted in 2009 (n = 4378), 2010 (n = 4359), 2012 (n = 4223) and 2015 (n = 4242). Generalised estimating equations assessed the level of knowledge about harms of tobacco use across four waves. Multivariable logistic regressions assessed whether knowledge of health effects from cigarette smoking and ST use in 2015 differed by user group. In 2015 survey, most tobacco users were aware that cigarette smoking causes stroke (92%), lung cancer (97%), pulmonary tuberculosis (97%) and ST use causes mouth cancer (97%) and difficulty in opening mouth (80%). There were significant increases in the total knowledge score of smoking related health harm from 2010 to 2012 (mean difference = 0.640; 95% confidence interval [CI] 0.537, 0.742) and 2012 to 2015 (mean difference = 0.555; 95% CI 0.465, 0.645). Participants had greater odds of awareness for ST health effects from 2010 to 2015. The results suggest that increasing efforts of awareness policy interventions is having a positive effect on tobacco-related knowledge in Bangladesh. These policy initiatives should be continued to identify optimal methods to facilitate behaviour change and improve cessation of smoking and ST use.

Youth and adult understanding of public displays of information about harmful constituents in cigarette smoke

The U.S. FDA is required by law to publicly display a list of harmful and potentially harmful constituents (HPHCs) “by brand and by quantity in each brand and subbrand” in a format that is “understandable and not misleading to a lay person.” An online experiment examined youth and adult understanding of which HPHCs are present in cigarette smoke, understanding of health effects of smoking cigarettes, and endorsement of misleading information after viewing HPHC information displayed in one of six formats. We recruited youth (N = 1324) and adults (N = 2904) from an online panel and randomized them to one of six formats of presenting HPHC information. Participants responded to survey items before and after exposure to an HPHC format. Understanding of HPHCs in cigarette smoke and understanding of health effects of cigarette smoking significantly increased pre- to post-exposure for all formats. Respondents (20.6% to 73.5%) endorsed misleading beliefs after exposure to information about HPHCs. Endorsement of the one misleading belief that was measured pre- and post-exposure significantly increased for viewers of four formats. All formats increased understanding of HPHCs in cigarette smoke and the health effects of smoking cigarettes, but some participants endorsed each misleading belief after exposure to HPHC information.

Health effects of cigarette smoking – review of the past 5 years

Tobacco consumption poses a serious health hazard. Globally, despite of overall anti-tobacco policy, smoking still stays an important problem for public. Compounds in tobacco smoke cause adverse effects. Nearly all smokers have information about smoking hazards, but often this still does not cause them to quit smoking. The reason is that negative consequences of tobacco smoking are prolonged in time. It is necessary to enhance anti-tobacco campaign, especially considering the fact that tobacco harms not only smokers but also nonsmokers due to secondhand smoke inhalation. In this paper we have presented information on health hazards of tobacco smoking based on the literature review of the last five years. There are stated diseases for development of which tobacco smoking is a serious risk factor.

Does Smoking Affect OSA? What about Smoking Cessation?

The connection between smoking and Obstructive sleep apnea (OSA) is not yet clear. There are studies that have confirmed the effect of smoking on sleep disordered breathing, whereas others did not. Nicotine affects sleep, as smokers have prolonged total sleep and REM latency, reduced sleep efficiency, total sleep time, and slow wave sleep. Smoking cessation has been related with impaired sleep. The health consequences of cigarette smoking are well documented, but the effect of smoking cessation on OSA has not been extensively studied. Smoking cessation should improve OSA as upper airway oedema may reduce, but there is limited data to support this hypothesis. The impact of smoking cessation pharmacotherapy on OSA has been studied, especially for nicotine replacement therapy (NRT). However, there are limited data on other smoking cessation medications as bupropion, varenicline, nortriptyline, clonidine, and cytisine. The aim of this review was to explore the current evidence on the association between smoking and OSA, to evaluate if smoking cessation affects OSA, and to investigate the possible effects of different pharmacologic strategies offered for smoking cessation on OSA.

The effects of prenatal smoke exposure on language development ‐ a systematic review

The negative health effects of cigarette smoking during pregnancy (SDP) on the foetus are well known. Despite previous reports of poor cognitive performance in offspring exposed to SDP, few studies specifically consider language outcomes according to maternal smoking. In this study, we systematically review the literature to assess the relationships between SDP and child language. Of the 14 studies reviewed, 13 (93%) reported significant associations between maternal smoking or exposure and language outcomes. Despite this consistent association, only 8 of the 13 studies reporting associations (62%) concluded direct relationships between exposure and outcome. The remaining studies suggested that the relationship between smoking and language could be explained by factors such as maternal IQ, socioeconomic status (SES) and parental age. Future studies should apply careful study designs allowing for confounding factors across child, parental, environmental and genetic influences. Our review suggests that smoking cessation is likely to positively affect child language outcomes. Highlights Does maternal smoking during or exposure to smoking during pregnancy affect the language outcomes in exposed offspring? A systematic review of the literature highlighted consistent negative effects of smoking or smoke exposure during pregnancy on language outcomes. Exposure to SDP is associated with language. Mothers must be educated regarding the effects of tobacco smoking on language outcomes.

Oral and periodontal implications of tobacco and nicotine products.

Tobacco use contributes to more mortality and morbidity globally than any other behavioral risk factor. Adverse effects do not spare the oral cavity, with many oral diseases more common, and treatments less successful, in the tobacco-using patient. Many of the oral health effects of cigarette smoking are well established, but other forms of tobacco, including cigars and smokeless tobacco, merit dental professionals' attention. Recently, an expanding variety of new or emerging tobacco and/or nicotine products has been brought to market, most prominently electronic cigarettes, but also including heated tobacco and other noncombustible nicotine products. The use of cannabis (marijuana) is increasing and also has risks for oral health and dental treatment. For the practicing periodontist, and all dental professionals, providing sound patient recommendations requires knowledge of the general and oral health implications associated with this wide range of tobacco and nicotine products and cannabis. This review provides an overview of selected tobacco and nicotine products with an emphasis on their implications for periodontal disease risk and clinical management. Also presented are strategies for tobacco use counselling and cessation support that dental professionals can implement in practice.

Influence of Warning Statements on Understanding of the Negative Health Consequences of Smoking.

Pursuant to the Tobacco Control Act (TCA), the US Food and Drug Administration (FDA) is developing new cigarette health warnings to convey the negative health consequences of cigarette smoking. This study assessed which of 15 revised warning statements (10 on topics similar to TCA statements and 5 on other topics) promoted greater understanding of cigarette smoking risks relative to TCA statements. In February 2018, adolescent and adult smokers and adolescents susceptible to smoking (n = 2505) completed an online experiment. Control condition participants viewed TCA statements; treatment condition participants viewed combinations of TCA and revised statements. Analyses compared revised statements to TCA statements on the same health topic or to randomly selected TCA statements if there were no statements on the same topic. Relative to TCA statements, 12 of 15 revised statements were more likely to be considered new information, and 12 resulted in more self-reported learning. Three revised statements made participants think more about health risks than TCA statements; the reverse was true for one revised statement. Participants rated most TCA and revised statements as moderately believable and informative. Seven revised statements were found to be less believable and factual, and one revised statement more believable and factual. Treatment condition participants correctly selected more smoking-related health conditions than control condition participants (13.79 versus 12.42 of 25). Findings suggest that revised statements can promote greater understanding of cigarette smoking risks. Results informed FDA's selection of warning text that was paired with images for testing in a follow-up study. The US FDA may adjust the text of the cigarette warning statements provided in the TCA if the revised statements promote greater public understanding of the negative health consequences of cigarette smoking. Most of the revised warning statements tested were more likely to be considered new information and resulted in more self-reported learning compared with paired TCA statements, providing support for using revised statements as part of cigarette health warnings. These results informed the development of pictorial cigarette warnings by FDA that were tested in a follow-up study and included in a proposed rule.

Knowledge and Determinants of Health Consequences of Cigarette Smoking Among Vietnamese Adults, 2015.

Background. Vietnam was one of 16 countries that implemented the second round of the GATS (Global Adult Tobacco Survey) in 2015. Aims. To assess knowledge and determinants of health consequences of different types of cigarette smoking among Vietnamese adults. Methods. A cross-sectional study among adults aged 15 years combined with using 15% of the master sample from the national sampling frame of the population and housing census was conducted. Multilevel analysis using Poisson regression was undertaken. Results. Knowledge on the health consequences of cigarette smoking has not significantly improved in the GATS-2015. Adults believe that active smoking had more of an impact on health than secondhand smoking and 24.5% and 43% of them answered that smoking light and e-cigarettes, respectively, causes less harm than regular cigarettes, and 17.3% and 18.1% of adults are not aware of the difference between them, respectively. Conclusion. Household and community's role had little impact in the adult knowledge of smoking health consequences. It is necessary to disseminate information on the "other tobacco product" and to improve public knowledge on specific health consequences, to enhance household and community's role in conveying health education messages to individuals.

Using Mass Media Communications to Promote Smoking Cessation in Turkey and Post-test Measurement

Background and context: In 2017 March, Turkey has launched a public campaign to promote smoking cessation among adults. The purpose of the campaign is to create awareness about the risks and health effects of cigarette smoking and to promote behavioral change, based on health behavior model (HBM.) Aim: To encourage behavioral change by decreasing perceived benefits of smoking and increasing perception of threat related to smoking among the target audience. decreasing perception of barrier related to behavioral change and increase sense of self-efficacy among the target audience Strategy/Tactics: · Three television advertisements aiming to increase perceived threat of smoking and to increase perceived benefits of quitting · Two radio advertisements aiming to increase self-efficacy to quit, · Web portal ( birakabilirsin.org ) aiming to increase self-efficacy to quit Outcomes: After the ad campaign, a quantitative survey was carried out aiming to measure the attitude about the key messages of the campaign and intention to quit smoking. The survey was conducted in October-November 2017 and used the in-person household survey method to reach samples of current cigarette smokers, ex-smokers and nonsmokers in Turkey aged 18 years and above (planned sample size is 1700). According to the results of the postcampaign evaluation, the messages of the campaign were retained with a high 85.5% Nearly half of those saying they quit after the campaign started declared that the campaign was effective in helping them quit smoking. 48% of those quit said that the campaign helped them to not restart smoking. 80% of those who never smoked stated that the campaign decreased their desire to try smoking. Half of the survey participants heard of the campaign Web site 7% of the people who heard of the Web site visited it. 68% of the participants who visited the Web site believed that the Web site would help in quitting smoking. What was learned: The results of the postcampaign evaluation show that the campaign was successful in establishing perceived risk of smoking, changing perception and attitudes and developing the intention of quitting smoking among the target population. The campaign also helped people to actually quit smoking. The mandated free publication of antitobacco PSAs in all local and national channels according to the Turkish Tobacco Control Laws positively affected the public access of the campaign.

Cigarette Smoking: An Assessment of Tobacco's Global Environmental Footprint Across Its Entire Supply Chain.

While the health effects of cigarette smoking are well recognized and documented, the environmental impacts of tobacco are less appreciated and often overlooked. Here, we evaluate tobacco's global footprint across its entire supply chain, looking at resource needs, waste, and emissions of the full cradle-to-grave life cycle of cigarettes. The cultivation of 32.4 Mt of green tobacco used for the production of 6.48 Mt of dry tobacco in the six trillion cigarettes manufactured worldwide in 2014, were shown to contribute almost 84 Mt CO2 equiv emissions to climate change-approximately 0.2% of the global total, 490 000 tonnes 1,4-dichlorobenzene equiv to ecosystem ecotoxicity levels, and over 22 billion m3 and 21 Mt oil equiv to water and fossil fuel depletion, respectively. A typical cigarette was shown to have a water footprint of 3.7 L, a climate change contribution of 14 g CO2 equiv, and a fossil fuel depletion contribution of 3.5 g oil equiv. Tobacco competes with essential commodities for resources and places significant pressures on the health of our planet and its most vulnerable inhabitants. Increased awareness, as well as better monitoring and assessment of the environmental issues associated with tobacco, should support the current efforts to reduce global tobacco use as an important element of sustainable development.

"GiochiAMO": a school-based smoking and alcohol prevention program for children - a pilot randomized field trial. Part 2.

Young people who begin to smoke at an early age are at a higher risk of becoming occasional or regular smokers and establishing a premature dependence. It is fundamental to act as soon as possible, from very early childhood, to prevent harmful behaviors for health such as smoking and drinking alcohol. Young people must be encouraged to adopt healthy lifestyles. The aim of the study is two-fold. First, increasing the knowledge about the negative health effects of cigarette smoking and alcohol consumption among children aged 9-10 years; and second, to introduce and reinforce life skills in order to learn how to tackle social influences that encourage children to smoke and to drink alcohol. A pilot randomized field trial was conducted in May-June 2017. Four primary school classes in Rome were randomized to either the intervention or the control group. Both groups participated in an oral presentation about the risks and consequences of smoking and alcohol consumption, and the concept of life skills. The intervention group participated in two gaming sessions, each lasting 1.5 hours. Children were involved in six games aiming to deliver and reinforce knowledge about the target themes of the study. A 21 multi-response questions questionnaire was handed out to both groups at the beginning and at the end of the study. Eleven questions were about smoking; five questions about alcohol; five questions about life skills. Each question item included one correct answer. For each domain, a score was computed (total; smoking; alcohol; life skills). 67 children participated in the study (34 in the intervention and 33 in the control group). Univariate analyses showed significant differences among the intervention group before and after the intervention for total score (p<0.001), smoke score (p<0.001), and life skills score (p=0.003). No significant differences among the intervention group before and after the intervention were reported for alcohol score (p=0.076). Regarding the control group univariate analysis showed significant differences in total score (p=0,001) and life skills score (p=0.005). Multivariate analysis revealed that enrollment in the intervention was the only variable that had a significant positive influence on smoking knowledge score (beta=1.070, p=0.05). This pilot study shows that the intervention was effective among the intervention group for all the scores: total score, smoke score and life skills score, but ineffective for alcohol. Overall, the combination of a presentation and games was effective in increasing life skills knowledge.

Clinical Effects of Cigarette Smoking: Epidemiologic Impact and Review of Pharmacotherapy Options.

Cigarette smoking—a crucial modifiable risk factor for organ system diseases and cancer—remains prevalent in the United States and globally. In this literature review, we aim to summarize the epidemiology of cigarette smoking and tobacco use in the United States, pharmacology of nicotine—the active constituent of tobacco, and health consequence of cigarette smoking. This article also reviews behavioral and pharmacologic interventions for cigarette smokers and provides cost estimates for approved pharmacologic interventions in the United States. A literature search was conducted on Google Scholar, EBSCOhost, ClinicalKey, and PubMed databases using the following headings in combination or separately: cigarette smoking, tobacco smoking, epidemiology in the United States, health consequences of cigarette smoking, pharmacologic therapy for cigarette smoking, and non-pharmacologic therapy for cigarette smoking. This review found that efficacious non-pharmacologic interventions and pharmacologic therapy are available for cessation of cigarette smoking. Given the availability of efficacious interventions for cigarette smoking cessation, concerted efforts should be made by healthcare providers and public health professionals to promote smoking cessation as a valuable approach for reducing non-smokers’ exposure to environmental tobacco smoke.

Influence of Health Warnings on Beliefs about the Health Effects of Cigarette Smoking, in the Context of an Experimental Study in Four Asian Countries.

Cigarette package health warnings can be an important and low-cost means of communicating the health risks of smoking. We examined whether viewing health warnings in an experimental study influenced beliefs about the health effects of smoking, by conducting surveys with ~500 adult male smokers and ~500 male and female youth (age 16–18) in Beijing, China (n = 1070), Mumbai area, India (n = 1012), Dhaka, Bangladesh (n = 1018), and Republic of Korea (n = 1362). Each respondent was randomly assigned to view and rate pictorial health warnings for 2 of 15 different health effects, after which they reported beliefs about whether smoking caused 12 health effects. Respondents who viewed relevant health warnings (vs. other warnings) were significantly more likely to believe that smoking caused that particular health effect, for several health effects in each sample. Approximately three-quarters of respondents in China (Beijing), Bangladesh (Dhaka), and Korea (which had general, text-only warnings) thought that cigarette packages should display more health information, compared to approximately half of respondents in the Mumbai area, India (which had detailed pictorial warnings). Pictorial health warnings that convey the risk of specific health effects from smoking can increase beliefs and knowledge about the health consequences of smoking, particularly for health effects that are lesser-known.

The association between cigarette smoking, virologic suppression, and CD4+ lymphocyte count in HIV-Infected Russian women

ABSTRACTCigarette smoking among people living with HIV/AIDS is associated with significant morbidity and mortality, but findings regarding the association between cigarette smoking and HIV viral load and CD4+ lymphocyte counts have been inconsistent. This study characterized the prevalence of cigarette smoking among HIV-infected Russian women and examined the association between smoking frequency and quantity and HIV viral load and CD4+ lymphocyte counts. HIV-infected Russian women (N = 250; M age = 30.0) in St. Petersburg, Russia, completed an audio computer-assisted self-interview survey assessing cigarette use, antiretroviral medication adherence, and provided blood samples assayed for HIV viral load and CD4+ lymphocyte counts. The majority (60.4%) reported cigarette smoking in the past month; 49.0% of recent smokers were classified as moderate or heavy smokers, defined as smoking ≥10 cigarettes daily. Viral load status did not differ between infrequent smokers and regular smokers. However, moderate/heavy smokers (relative to light smokers) were more likely to have a detectable viral load (AOR = 2.3, 95% CI: 1.1, 5.1). There were no significant differences in CD4+ lymphocyte counts by smoking frequency or quantity of cigarettes smoked. Results highlight the need for additional research to examine the association between cigarette smoking and virologic suppression and markers of HIV disease progression. Adverse health consequences of cigarette smoking coupled with a potential link between heavy smoking and poor virologic suppression highlight the need for assessment of cigarette use and provision of evidence-based smoking-cessation interventions within HIV medical care.

Impact of The Real Cost Campaign on Adolescents’ Recall, Attitudes, and Risk Perceptions about Tobacco Use: A National Study

The Food and Drug Administration’s (FDA) The Real Cost campaign advertisements (ads) have targeted U.S. youth with messages designed to prevent and reduce tobacco use. This study examined exposure to The Real Cost campaign, including ad and slogan recall, and associations with attitudes and risk perceptions among U.S. adolescents. We analyzed data from a nationally representative sample of adolescents aged 13 to 17 years (n = 1125) surveyed by phone from October 2014 to June 2015. We assessed aided recall of and attitudes toward four campaign ads and the one slogan. Logistic regression models assessed whether aided recall of The Real Cost ads or slogan was associated with perceived likelihood of serious health consequences of cigarette smoking. Most (88%) adolescents reported seeing or hearing at least one of four ads for The Real Cost, and 54% recalled The Real Cost slogan. The majority of adolescents reported more negative attitudes toward tobacco products after seeing or hearing the ads. Recall of any The Real Cost ad was significantly associated with greater perceptions of serious health consequences of cigarette smoking (Adjusted Odd Ratios (AOR) = 5.58, 95% Confidence Interval (CI) = 1.20–25.90). The FDA’s The Real Cost campaign has achieved very high reach and is associated with more negative attitudes toward tobacco products and greater risk perceptions of cigarette smoking among U.S. adolescents.

The impact of genetic variation and cigarette smoke on DNA methylation in current and former smokers from the COPDGene study

DNA methylation can be affected by systemic exposures, such as cigarette smoking and genetic sequence variation; however, the relative impact of each on the epigenome is unknown. We aimed to assess if cigarette smoking and genetic variation are associated with overlapping or distinct sets of DNA methylation marks and pathways. We selected 85 Caucasian current and former smokers with genome-wide single nucleotide polymorphism (SNP) genotyping available from the COPDGene study. Genome-wide methylation was obtained on DNA from whole blood using the Illumina HumanMethylation27 platform. To determine the impact of local sequence variation on DNA methylation (mQTL), we examined the association between methylation and SNPs within 50 kb of each CpG site. To examine the impact of cigarette smoking on DNA methylation, we examined the differences in methylation by current cigarette smoking status. We detected 770 CpG sites annotated to 708 genes associated at an FDR < 0.05 in the cis-mQTL analysis and 1,287 CpG sites annotated to 1,242 genes, which were nominally associated in the smoking-CpG association analysis (Punadjusted < 0.05). Forty-three CpG sites annotated to 40 genes were associated with both SNP variation and current smoking; this overlap was not greater than that expected by chance. Our results suggest that cigarette smoking and genetic variants impact distinct sets of DNA methylation marks, the further elucidation of which may partially explain the variable susceptibility to the health effects of cigarette smoking. Ascertaining how genetic variation and systemic exposures differentially impact the human epigenome has relevance for both biomarker identification and therapeutic target development for smoking-related diseases.

The mediating effect of body mass index on the relationship between cigarette smoking and atopic sensitization in Chinese adults.

Background: It is unclear whether the relationship between cigarette smoking and atopy is mediated by body fat mass, such as the Body Mass Index (BMI). We assessed the mediating role of BMI on the relationship between smoking and atopy in Chinese adults. Methods: A hospital-based case-control study of 786 atopic cases and 2771 controls was conducted in adults aged 18 years or older from March 2010 to September 2014 in Harbin, China. Mediation models were used to estimate the indirect effects of smoking on atopic sensitization through BMI. Results: Compared to non-smokers, light smokers and moderate smokers had a lower risk of inhalant allergen sensitization. The indirect effect of smoking and sensitization to aeroallergens were only observed in light smokers (point estimate, −0.026; 95% CI, −0.062 to −0.004). The mediating roles of BMI on the relationships between smoking and other types of allergic sensitization were not statistically significant. Conclusion: BMI appeared to partially mediate the effect of light smoking on sensitization to aeroallergens. However, considering the other harmful health effects of cigarette smoking, the effective method to lower the incidence of atopy would be to decrease body fat mass by physical exercise and employing other more healthy ways of living rather than smoking.

Health care expenditures attributable to smoking in military veterans.

The health effects of cigarette smoking have been estimated to account for between 6%-8% of U.S. health care expenditures. We estimated Veterans Health Administration (VHA) health care costs attributable to cigarette smoking. VHA survey and administrative data provided the number of Veteran enrollees, current and former smoking prevalence, and the cost of 4 types of care for groups defined by age, gender, and region. Cost and smoking status could not be linked at the enrollee level, so we used smoking attributable fractions estimated in sample of U.S. residents where the linkage could be made. The 7.7 million Veterans enrolled in VHA received $40.2 billion in VHA provided health services in 2010. We estimated that $2.7 billion in VHA costs were attributable to the health effects of smoking. This was 7.6% of the $35.3 billion spent on the types of care for which smoking-attributable fractions could be determined. The fraction of inpatient costs that was attributable to smoking (11.4%) was greater than the fraction of ambulatory care cost attributable to smoking (5.3%). More cost was attributable to current smokers ($1.7 billion) than to former smokers ($983 million). The fraction of VHA costs attributable to smoking is similar to that of other health care systems. Smoking among Veterans is slowly decreasing, but prevalence remains high in Veterans with psychiatric and substance use disorders, and in younger and female Veterans. VHA has adopted a number of smoking cessation programs that have the potential for reducing future smoking-attributable costs.
