Implementation level indicators of public facilities in Surabaya to smoke-free area regulation

Background and purpose: The regulation of smoke-free area in Surabaya was adopted since 2008 and amended in 2019. Hotel, restaurants, and cafes are smokefree dedicated area under the regulation. Therefore, it is very important to review the implementation level of smoke-free area regulations in public places such as hotels, restaurants and cafes. This study aims to analyze how strong the indicators that forms the implementation level of public facilities with smoke free area regulations in Surabaya. Methods: This was a cross sectional survey carried out in 88 public facilities consisting of hotels and restaurants between June-August 2021. Confirmatory Factor Analysis (CFA) was carried out with the Analysis of Moment Structures (AMOS) Application to test the strength of each smoke-free area monitoring indicators that forms the implementation level of these public facilities. These indicators include: awareness of smoke-free area regulations, smoke-free area internal promotion, installation of smoke-free signs, no colaboration with tobacco industries, no violations and owning an internal policy related to smoke-free. Results: There were three strong indicators that are strongest in shaping smoke-free area implementation level at public facilities in Surabaya, including awareness of smoke-free area regulations (CFA 4.681), smoke-free area internal promotion (CFA 2.609) and installing a smoke-free sign (CFA 1.000). Meanwhile, the other three indicators showed weak association. Conclusion: Awareness of smoke-free area regulations, smoke-free area internal promotion and installation of smoke-free sign were the strong indicators for smokefree law (SFL) implementation. It is important to push for more internal dissemination involving cross sectors and improve other indicators.

Advancing the science of policy implementation: a call to action for the implementation science field.

Public policies have been essential in addressing many of the most pressing public health problems in the USA and around the world. A large and convincing body of multidisciplinary research has established the impacts or effectiveness of public policies, such as smoke-free air laws and nutrition standards, on improving health outcomes and behaviors. Most of this research assumes that because an evidence-based policy is adopted or takes effect, it is implemented as intended. This assumption, however, is often incorrect. Like with clinical guidelines and other interventions, implementation science has an important role to play in promoting the uptake and implementation of evidence-based public policies that promote public health. To realize this potential, there remains a critical need to first establish a common understanding of what public policy is, the role of specific policies in the context of implementation (i.e., is it the evidence-based intervention or the implementation strategy?), and to establish an appropriate methodological foundation for the field of policy implementation science. We recommend that the field must evolve to (i) include policy experts and actors on policy implementation science study teams; (ii) identify theories, models, and frameworks that are suitable for policy implementation science; (iii) identify policy implementation strategies; (iv) adapt and/or identify study designs best suited for policy implementation science research; and (v) identify appropriate policy implementation outcome measures.

Tobacco smoking, second-hand smoking exposure in relation to psychotic-like experiences in adolescents.

Previous literature supports that tobacco smoking and second-hand smoking (SHS) exposure were strongly associated with poor mental health in the general population. However, there is a lack of empirical data on the relationship between tobacco smoking, SHS exposure and psychotic-like experiences (PLEs). This study conducted a cross-sectional survey to explore PLEs and the associations of PLEs with tobacco smoking and SHS exposure among adolescents in China. A total sample of 67 182 Chinese adolescents were recruited from Guangdong province in China (53.7% boys, mean age = 12.79 years) from December 17 to 26, 2021. All adolescents have completed self-reported questionnaires on demographic characteristics, smoking status, SHS exposure and PLEs. Within the sample, only 1.2% of participants had an experience of tobacco smoking while approximately three-fifths reported being exposed to SHS. 10.7% of adolescents reported frequent PLEs over the past month. Adolescents who smoked showed a higher prevalence of PLEs than in non-smoking samples. After controlling for confounders, SHS exposure was a robust risk factor for PLEs with or without the effect of tobacco smoking. These findings support the importance of smoke-free legislation, and anti-smoking measures in educational settings directed at both adolescents and their caregiver, which may decrease occurring rates of PLEs among adolescents.

Potential short-term effects of tobacco control scheme under various application scenarios of tobacco control measures across the globe: a Meta-analysis

Objective: based on summarizing the simulation and prediction of tobacco control measures across the globe and sorting out the various scenarios of tobacco control measures, the potential short-term effects of seven tobacco control measures in different scenarios were systematically analyzed. Methods: Until April 2022, PubMed, Embase, EconLit, PsychINFO, and CINAHL databases were used to retrieve literature about tobacco control measures simulation and prediction models across the globe. Inclusion and exclusion criteria were strictly followed. Meta-analysis for the potential short-term effects of seven tobacco control measures in different scenarios was performed using the R software. Results: A total of 22 papers covering 16 countries were selected. Five studies were conducted in the United States, three in Mexico, and two in Italy. There were all papers with the measures to tax increases, smoke-free air laws, and mass media campaigns, 21 papers with youth access restrictions, 20 with marketing restrictions, and 19 with cessation treatment programs and health warnings. The tax increases had diverse influences on the price elasticity of different age groups. The price elasticity in the age group 15-17 years was the highest, which was 0.044 (95%CI: 0.038-0.051). The potential short-term effects of smoke-free air laws in workplaces were higher than in restaurants and other indoor public places. The effects of youth access restrictions were greater in the age group <16 years than in the age group 16-17. The stronger the implementation of other measures, the greater the potential short-term effects. A comparison of seven tobacco control measures showed that the cessation treatment programs increase in cessation rate was the highest, 0.404 (95%CI: 0.357-0.456). The reduction in smoking rate and reduction in initiation rate of youth access restrictions strongly enforced and publicized was the highest in the age group <16 years, 0.292 (95%CI: 0.269-0.315), and 0.292 (95%CI: 0.270-0.316). Conclusions: The potential short-term effects of seven tobacco control measures in different scenarios were evaluated more accurately and objectively through Meta-analysis. In the short term, cessation treatment programs will substantially increase smoking cessation rates, and strong youth access enforcement will sharply reduce smoking and initiation rates among adolescents under 16. These results also offer strong data-related support for the simulation and prediction of tobacco control measures in China and other countries.

Associations between e-cigarette policies and adolescent use and access to e-cigarettes

BackgroundTobacco control policies have been adapted to address rising levels of adolescent e-cigarette use. Despite new restrictions, adolescents are continuing to access e-cigarettes. MethodsWe linked 2015–2019 Youth Risk Behavior Survey data on 503,154 14–18-year-olds from 40 states with state-level e-cigarette minimum legal sales age (MLSA) laws, taxes, and smoke-free legislation. Using two-way fixed effects probit regression models, we first examined the associations between these statewide e-cigarette policies and adolescent use and, second, with access to e-cigarettes. We subsequently tested interactions between age and each policy and present average marginal effects as percentage point (pp) changes. ResultsWhile MLSA laws for e-cigarettes were associated with slight increases in e-cigarette use (2.72 pp; 1.29, 4.15), associations were no longer significant after at least 1-year post-implementation. MLSA laws were also associated with decreases in e-cigarette purchases in stores (-9.50 pp; -18.21, -0.79) and increases in acquiring them from someone else (13.26 pp; 4.10, 22.42), particularly among 18-year-olds. E-cigarette taxes were associated with decreases in use (-9.18 pp; -11.63, -6.73), but there were limited associations with e-cigarette access. While smoke-free legislation prohibiting e-cigarettes was associated with slight increases in use (1.87 pp; 0.23, 3.50), after at least 1-year post-implementation, they were associated with decreases in use. Smoke-free legislation was also associated with decreases in purchases in stores by 14-year-olds, but increases in online purchases by 18-year-olds. ConclusionUnderstanding the immediate and longer-term consequences of e-cigarette policies is essential to influence adolescent e-cigarette use. Adolescents will continue acquiring e-cigarettes across varying sources if measures are not taken to address access alongside policies aimed at reducing use.

Environmental tobacco smoke at home and in public places prior to smoking ban enforcement: Assessment by hair analysis in a population of young adult students.

Despite inititatives to reduce tobacco consumption, smoking remains a primary cause of death for both smokers and nonsmokers exposed to environmental tobacco smoke (ETS). The characteristics of some specific groups can make them more exposed to ETS or limit the benefit of prevention measures. This study investigated determinants of ETS in a population of young adult students, considered at higher risk of exposure due to their specific lifestyle. This cross-sectional study involved 90 students aged 20 ± 1.7 years, from the University of Luxembourg, prior to the smoking ban enforcement in public places in the country. Participants reported their tobacco consumption and exposure to ETS at home and/or in public places, and provided a hair sample analyzed for nicotine and cotinine. Nicotine and cotinine were significantly higher in smokers than in nonsmokers' hair in general (median: 2.6 vs. 0.9 ng/mg and 87.1 vs. 22.5 pg/mg respectively). However, nonsmokers exposed to ETS at home and in public places had comparable concentrations to smokers (nic = 2.2 ng/mg; cot = 56.2 pg/mg), whereas unexposed nonsmokers presented significantly lower values (nic = 0.4 ng/mg, cot = 8.5 pg/mg). Nonsmokers exposed to ETS only at home presented higher values than nonsmokers only exposed in public places (nic: 1.3 vs. 0.8 ng/mg, cot: 70.4 vs. 15.0 pg/mg). The study shows the widespread exposure to ETS in this population, the importance of exposure assessment, and the relevance of hair analysis for this purpose. Results suggest that ETS can lead to equivalent exposure to active smoking and that exposure at home can highly contribute to ETS, which is not solved by smoking ban in public places.

Promoting Global Adult Tobacco Control in South-East Asian Region: Nine-year Retrospective Analysis using World Health Organization MPOWER

It is noted that fire without smoke smokeless tobacco is one of the major scourges in the South-east Asia subcontinent, particularly India. It not only includes adult men and women users but a sizeable chunk entails Indian teenagers. What is worrying though, the models attempting to capture the global usage does not really has much to offer due to paucity of global data. That said, World Health Organization (WHO) has been at the forefront foreshadowing trends and using myriad policy initiatives to help developing countries combat the malaise. Mpower is one such policy framework by the WHO to help countries implement and manage tobacco control, the success of this country-tailored demand reduction interventionist program has lifted a country like Turkey from being one of the highest puffers to drastically reducing its tobacco usage and free smoking indoors by 100%. MPOWER has shown a stellar performance in averting 7.4 million deaths, 30 countries with more than 1 billion people have best pictorially represented health warnings and labels, smoke-free laws and appropriate taxation rules to curb the menace. Aim: In light of aforementioned, the aim of this study was to perform the quantitative analysis of WHO report on tobacco control and to get an insight to what extend the program has been successful and the best practices that could potentially be replicated. Methodology: The MPOWER composite score was built by employing 6 MPOWER scores using the validated checklist outlined by Iranian and international tobacco control specialists in their study on tobacco control. The independent scores and cutoffs thereof were set in consonance with the key sections of the MPOWER 2011 report. Results: MPOWER composite scores that measured policy implementation were then linked to cigarette smoking prevalence and consumption data. An encouraging trend was observed, for example, the highest scores were observable in 2019 and there was noticeable increase in scores of adult daily smoking prevalence (&lt;15 years), cessation programs, and in health warning on cigarette packages. Laws are toothless without adequate intervention at ground level and it was patently clear from monitoring of prevalence data, for example, there was abysmally poor compliance rate, especially with respect to advertisements and other smoke –free policies. The results were mixed at best. Conclusion: The dozen countries present themselves as the best replica in the implementation and enforcement of tobacco control program; however, little tweaks here and there to tailor it in accordance with socio-cultural aspects of countries are warranted.

Effects of chronic secondhand smoke exposure on cardiovascular regulation and the role of soluble epoxide hydrolase in mice.

Background: Secondhand smoke (SHS) is a significant risk factor for cardiovascular morbidity and mortality with an estimated 80% of SHS-related deaths attributed to cardiovascular causes. Public health measures and smoking bans have been successful both in reducing SHS exposure and improving cardiovascular outcomes in non-smokers. Soluble epoxide hydrolase (sEH) inhibitors have been shown to attenuate tobacco exposure-induced lung inflammatory responses, making them a promising target for mitigating SHS exposure-induced cardiovascular outcomes. Objectives: The objectives of this study were to determine 1) effects of environmentally relevant SHS exposure on cardiac autonomic function and blood pressure (BP) regulation and 2) whether prophylactic administration of an sEH inhibitor (TPPU) can reduce the adverse cardiovascular effects of SHS exposure. Methods: Male C57BL/6J mice (11weeks old) implanted with BP/electrocardiogram (ECG) telemetry devices were exposed to filtered air or 3mg/m3 of SHS (6hr/d, 5d/wk) for 12weeks, followed by 4weeks of recovery in filtered air. Some mice received TPPU in drinking water (15mg/L) throughout SHS exposure. BP, heart rate (HR), HR variability (HRV), baroreflex sensitivity (BRS), and BP variability were determined monthly. Results: SHS exposure significantly decreased 1) short-term HRV by ∼20% (p < 0.05) within 4weeks; 2) overall HRV with maximum effect at 12weeks (-15%, p < 0.05); 3) pulse pressure (-8%, p < 0.05) as early as week 4; and 4) BRS with maximum effect at 12weeks (-11%, p < 0.05). Four weeks of recovery following 12weeks of SHS ameliorated all SHS-induced cardiovascular detriments. Importantly, mice exposed to TPPU in drinking water during SHS-related exposure were protected from SHS cardiovascular consequences. Discussion: The data suggest that 1) environmental relevant SHS exposure significantly alters cardiac autonomic function and BP regulation; 2) cardiovascular consequences from SHS can be reversed by discontinuing SHS exposure; and 3) inhibiting sEH can prevent SHS-induced cardiovascular consequences.

China's Smoke-free Policies in Public Place and the Smoking Cessation Status of Smokers.

Smoking remains a major health risk factor and China is the world's largest consumer of tobacco. Smoke-free policies in public places are a powerful weapon in tobacco control. Therefore, the aim of this study was to assess the association between smoke-free policies in public places and smoking cessation among smokers in China from 2012 to 2020. In this study, we assessed the impact of smoke-free public places policies on smoking cessation situation among smokers aged 16years and older. We do this by conducting a difference-in-differences analysis using data from the China Family Panel Study (CFPS) 2012-2020. By 2020, about 60.2% of the cities were covered by partial smoke-free policies and about 38.5% by comprehensive smoke-free policies. Based on the results of the study, we found that the medium-term effect model (Model 2, 2012:2016; Model 3, 2012:2018) of the impact of partial smoke-free policies on smoking cessation was not statistically significant using 2012 as the study baseline; the short-term effect model (Model 1; 2012:2014; P< .01) and the long-term effect model (Model 4; 2012:2020; P< .05) were statistically significant; the effect of a comprehensive smoke-free policy on smoking cessation (Model 5; 2012:2020; P<.05) was statistically significant. China's existing comprehensive smoke-free policies have had a modest impact on smoking cessation among the smoking population, and a strong, comprehensive national smoke-free law is urgently needed to achieve greater public health outcomes. Smoke-free policies are an important intervention to influence smoking behavior. This study demonstrates that comprehensive smoke-free policies in public places in China can effectively influence smoking behavior and show long-term trends in smoke-free behavior, while also reflecting the need to promote comprehensive smoke-free policies. This study provides a basis for the implementation of comprehensive smokefree policies into law and also provides a basis for policy makers.

Knowledge, attitudes and perceptions of workers in indoor bars, beer halls and discotheques towards exposure to second-hand smoking in the two cities in Swaziland

Second-hand smoking is a serious health hazard causing approximately 41000 deaths from lung cancer, respiratory infections, asthma, coronary heart disease and stroke globally each year. Evidence suggests that workers in bars, beer halls and discotheques are more exposed to second- hand smoking compared to other workers in general. Protection of these workers through enactment of smoke-free legislation and attitudes of these workers towards such legislation are key variables of compliance. This study aimed to describe the knowledge of the adverse effects of second-hand smoking, attitudes and perceptions of workers towards the practice. The results suggest that most workers knew what second-hand smoking was and that it could cause lung cancer, coronary heart disease and asthma but undermined the fact that continued exposure or exposure to low levels could lead to severe disease or death. Fifty-four percent of the respondents showed good knowledge and 36% showed fair knowledge of the adverse effects of exposure to second-hand smoke. Respondents mentioned lung cancer (100%), increased coughing (90%), asthma (60%) and heart disease (30%) as possible adverse effects. The knowledge was not different among workers who smoked and those who did not smoke (never smoked or ex- smokers) (p=0.1041). However, both smokers and non-smokers did not believe that exposure to second-hand smoke could lead to early death (p=0.8864). The suggestions that smoking should be banned in all indoor workplaces was accepted by non-smokers but rejected by smokers (p=0.0001). So was the suggestion of increasing tax on cigarettes (p&lt;0.0001). Legislation banning smoking in indoor workplaces is contained in the Swaziland Tobacco Products Control Act (2013) that is still waiting to be enforced and as such, indoor smoking is not banned in the country. Sixty-seven per cent of the participants were not aware of the existence of legislation aimed at protecting them against exposure to second-hand smoke in indoor workplaces. It is suggested that the enforcement of the Swaziland Tobacco Control Act (2013), which purports to impose a comprehensive ban of indoor smoking be speeded up so that indoor air quality could improve. Mechanisms to monitor adherence to the complete ban are likely to speed up improvement of the health of many indoor workers in bars, beer halls and discotheques that are exposed for lengthy periods. Enforcement of the Act should include creation of programmes to create awareness of the risks faced by the workers.

The Middle-Out Perspective: an approach to formalise 'normal practice' in public health advocacy.

The middle-out perspective (MOP) provides a lens to examine how actors positioned between government (top) and individuals (bottom) act to promote broader societal changes from the middle-out (rather than the top-down or bottom-up). The MOP has been used in recent years in the fields of energy, climate change, and development studies. We argue that public health practitioners involved with advocacy activities and creating alliances to amplify health promotion actions will be familiar with the general MOP concept if not the formal name. The article aims to demonstrate this argument. This article introduces the MOP conceptual framework and customises it for a public health audience by positioning it among existing concepts and theories for actions within public health. Using two UK case studies (increasing signalised crossing times for pedestrians and the campaign for smoke-free legislation), we illustrate who middle actors are and what they can do to result in better public health outcomes. These case studies show that involving a wider range of middle actors, including those not traditionally involved in improving the public's health, can broaden the range and reach of organisations and individuals involving in advocating for public health measures. They also demonstrate that middle actors are not neutral. They can be recruited to improve public health outcomes, but they may also be exploited by commercial interests to block healthy policies or even promote a health-diminishing agenda. Using the MOP as a formal approach can help public health organisations and practitioners consider potential 'allies' from outside traditional health-related bodies or professions. Formal mapping can expand the range of who are considered potential middle actors for a particular public health issue. By applying the MOP, public health organisations and staff can enlist the additional leverage that is brought to bear by involving additional middle actors in improving the public's health.

Smoke-free homes in Poland during the COVID-19 pandemic - a nationwide cross-sectional survey.

Secondhand smoke exposure causes serious health problems. Banning smoking in public venues decreases exposure to secondhand smoke. However, the implementation of smoke-free rules in a private setting (including homes) is largely voluntary. This study aimed to assess the prevalence and characteristics of voluntary smoke-free home rules in Poland during the COVID-19 pandemic as well as to identify factors associated with the voluntary implementation of smoking bans at home. This cross-sectional survey was conducted in March 2022 with a nationally representative sample of 1090 individuals aged ≥18 years in Poland. Data were collected using a computerassisted web interviewing (CAWI) technique. The research tool was an original questionnaire developed for the purpose of this study. Nationally, 60.6% of individuals had total ban on smoking in home (100% smoke-free home rules), 34.0% had implemented a partial smokefree home rule and 5.4% had not implemented any smoke-free home rules. Over three-quarters of non-smokers (76.8%) and only one-fifth of smokers (20.7%) had adopted a full smoke-free home rule. In multivariate logistic regression analysis, males (OR = 1.65, 95% CI: 1.22-2.22, p < 0.01), non-smokers (OR = 13.78, 95% CI: 9.80-19.38, p < 0.001), respondents who had higher education (OR = 1.57, 95% CI: 1.15-2.14, p < 0.01) as well as those who lived alone (OR = 2.44, 95% CI: 1.52-3.90, p < 0.001) had higher odds of having a 100% smoke-free home rule. This study demonstrated the negative impact of the COVID-19 pandemic on the implementation of smoke-free home rules in Poland. Less than two-thirds of the Polish population has adopted a total smoke-free home rule, with significant gaps between smokers and nonsmokers. Information on current voluntary smoke-free rules will be useful for further implementation of the smoke-free law in Poland. Int J Occup Med Environ Health. 2023;36(1):84-95.

Sources of Tobacco Smoke Exposure and Their Associations With Serum Cotinine Levels Among US Children and Adolescents.

We assessed tobacco smoke exposure (TSE) levels based on private and public locations of TSE according to race and ethnicity among US school-aged children ages 6-11 years and adolescents ages 12-17 years. Data were from 5296 children and adolescents who participated in the National Health and Nutrition Examination Survey (NHANES) 2013-2018. Racial and ethnic groups were non-Hispanic white, black, other or multiracial, and Hispanic. NHANES assessed serum cotinine and the following TSE locations: homes and whether smokers did not smoke indoors (home thirdhand smoke [THS] exposure proxy) or smoked indoors (secondhand [SHS] and THS exposure proxy), cars, in other homes, restaurants, or any other indoor area. We used stratified weighted linear regression models by racial and ethnic groups and assessed the variance in cotinine levels explained by each location within each age group. Among 6-11-year-olds, exposure to home THS only and home SHS + THS predicted higher log-cotinine among all racial and ethnic groups. Non-Hispanic white children exposed to car TSE had higher log-cotinine (β = 1.64, 95% confidence interval [CI] = 0.91% to 2.37%) compared to those unexposed. Non-Hispanic other/multiracial children exposed to restaurant TSE had higher log-cotinine (β = 1.13, 95% CI = 0.23% to 2.03%) compared to those unexposed. Among 12-17-year-olds, home SHS + THS exposure predicted higher log-cotinine among all racial and ethnic groups, except for non-Hispanic black adolescents. Car TSE predicted higher log-cotinine among all racial and ethnic groups. Non-Hispanic black adolescents with TSE in another indoor area had higher log-cotinine (β = 2.84, 95% CI = 0.85% to 4.83%) compared to those unexposed. TSE location was uniquely associated with cotinine levels by race and ethnicity. Smoke-free home and car legislation are needed to reduce TSE among children and adolescents of all racial and ethnic backgrounds. Racial and ethnic disparities in TSE trends have remained stable among US children and adolescents over time. This study's results indicate that TSE locations differentially contribute to biochemically measured TSE within racial and ethnic groups. Home TSE significantly contributed to cotinine levels among school-aged children 6-11 years old, and car TSE significantly contributed to cotinine levels among adolescents 12-17 years old. Racial and ethnic differences in locations of TSE were observed among each age group. Study findings provide unique insight into TSE sources, and indicate that home and car smoke-free legislation have great potential to reduce TSE among youth of all racial and ethnic backgrounds.

Socio-temporal contextual and community factors associated with daily exclusive ENDS use and dual use with tobacco cigarettes among adolescent vapers: an ecological momentary assessment study

BackgroundAdolescents who dual use ENDS with tobacco cigarettes are more likely to have an increased risk of developing dependence. Yet, little is understood about the factors driving dual use among adolescents. The current study sought to reveal the day-to-day socio-temporal contextual and community factors associated with adolescents’ use of electronic nicotine delivery systems (ENDS), and how these factors predict dual use with tobacco cigarettes.MethodsWe collected ecological momentary assessments (EMA) from a sample of 50 adolescent past two-week vapers (ages 14–17 years old) over 14 days. Daily EMA data were collected on ENDS and tobacco cigarette use, as well as a range of contextual (i.e., motivations to vape, location of vaping, who with when vaping) and community factors (i.e., exposure to peers vaping, to adults vaping, to ENDS advertising, to ENDS warning messages). Our primary analyses were multilevel regressions, accounting for daily observations nested within individuals (N = 700 observations).ResultsParticipants used ENDS exclusively on 44% of days and dual used ENDS and tobacco cigarettes on 8% of the days. Dual use days (versus exclusive ENDS use days) were associated with “vaping because tobacco use was prohibited” (OR = 34.65, p < .05). Also, dual use days (versus no use days) were associated with greater exposure to adults vaping (OR = 5.59, p < .05), peers vaping (OR = 7.48, p < .05), and (c) ENDS advertisements or promotions (OR = 2.12, p < .01), whereas exclusive use days (versus no use days) were only associated with greater exposure to peers vaping (OR = 2.58, p < .01).ConclusionsResults showed that exposure to peers and adults vaping and exposure to ENDS marketing were associated with same day dual use behaviors. And, that adolescents who dual used were motivated to use ENDS because they were easy to conceal. Findings support stricter regulation of ENDS marketing and for smoke-free air laws that include ENDS. In addition, these findings support prioritizing family- and school-based prevention programming that effectively communicates risk associated with ENDS use, including heightened risk of dual use and dependence. Such efforts can reduce the number of adolescents who use ENDS as well as the number who transition to tobacco cigarette use.

Prevalence and determinants of second-hand tobacco smoking in Pakistan.

Exposure to second-hand tobacco smoke is a public health problem in countries with high prevalence of active smoking such as Pakistan. However, few studies have assessed the prevalence and risk factors for exposure to second-hand tobacco smoke. To estimate the prevalence and factors associated with exposure to second-hand tobacco smoke in Pakistan. This study used data from the 2017-2018 Pakistan Demographic and Health Survey to calculate the prevalence and determinants of second-hand tobacco smoke exposure. Sociodemographic characteristics, family size and exposure to media by the respondents were the independent variables. The chi-square test and logistic regression analyses were used to evaluate the relationship between exposure to second-hand tobacco smoke and the independent variables.hy9. The survey included 61 940 adults, of which 30 027 (48.5%) were males and 31 913 (51.5%) females. The overall prevalence of exposure to second-hand tobacco smoke was 34.3%: 35.6% among males and 33.2% among females. Higher education level and rural residence were significantly positively associated with exposure to second-hand tobacco smoke among both sexes. Having a radio was inversely associated with exposure while having a television was positively associated with exposure among both sexes. Large family size was inversely associated with exposure. Currently and previously married females had significantly greater risk of exposure than never-married females. Tailored health interventions and policies are needed that target populations at high-risk of exposure to second-hand tobacco smoke. Strict smoking bans in public places should be implemented to limit exposure to second-hand tobacco smoke in Pakistan.

De-normalizing smoking in urban areas: Public smoking bans and smoking prevalence

The effectiveness of command-and-control policies related to tobacco use has been studied in high-income countries. Still, there is limited evidence of their effects in low and middle-income countries. We explore the case of Colombia, a country that introduced a business-supported smoking ban in bars and restaurants and all public indoor spaces in 2010. This paper investigates the effect of smoking bans in bars and restaurants on smoking prevalence in Bogotá, Colombia. In this paper, we use the matching with triple-differences technique in analyzing household consumption data from the 2007 and 2011 quality of life surveys. This is done by exploiting their geographical proximity and variation in the density of commercial areas. We found that after the smoking ban implementation, smoking prevalence reduced in households near high-density commercial blocks compared to households near low-density commercial blocks (−10.8 pp.). The impact is larger for households with children and older household heads. Since households near high-density commercial blocks are more frequently exposed to smoking than households near low-density commercial blocks, the former would be more willing to internalize the smoking de-normalization process.

Impact of smoke-free policies in hospitality venues and the home environment on smoking behaviour and exposure to second-hand smoke: results of two systematic reviews

Abstract Background Smoke-free policies (SFPs) have proven to be effective in protecting people from exposure to second-hand smoke (SHS) and lowering smoking rates. Our aims were to assess the impact of SFPs in hospitality venues (e.g. bars) on smoking behaviour of young people and to assess the impact of SFPs in the home environment on smoking behaviour and exposure to SHS. Methods Two reviews were conducted. The first was conducted in June 2020. We searched PubMed, Embase, and Scopus for studies that assessed the association between any form of SFPs in hospitality venues and a measure of smoking behaviour among young people (aged 10-24 years). The second review will be conducted in June 2022. Searches will be conducted in PubMed, Embase, Web of Science, PsycINFO and CENTRAL. We will search for studies that assess the association between any form of SFPs in the home environment (e.g. multi-unit housing) and a measure of smoking behaviour (e.g. initiation) or SHS exposure. Results Nine studies (publication years 2005-2016) were included in the first review, of which the majority used a quasi-experimental design. Four studies evaluated SFPs in hospitality venues specifically. Two studies reported that strict, but not weaker, SFPs decrease progression to established smoking. Two other studies provided mixed results. Five studies also included other workplaces, of which three studies found significant decreases in current smoking, smoking frequency, and/or smoking quantity. The results of the second review will be presented in detail during the workshop, however an exploration suggests that SFPs in the home environment may prevent smoking and SHS exposure. Conclusions Most studies of the first review found that SFPs in hospitality venues are associated with a decrease in smoking behaviour among young people. Their results indicate the need for strict smoke-free legislation without exemptions. The conclusions of the second review will be presented during the workshop.
