EVALUATING PATIENT AWARENESS OF SMOKING - RELATED ORAL HEALTH RISKSAMONG BATHINDARESIDENTS: A SURVEY- BASED STUDY

Background:Smoking poses serious risks to oral health, contributing to issues like gum disease, oral cancer, and impaired healing. However, many patients are not fully aware of these dangers. Aim and Objective:The objective of this study is to assess the level of awareness among dental patients regarding smoking & detrimental effects of smoking & to explore patients perceptions of how smoking affects their overall oral health. Materials and Methods:A questionnaire based observational survey was carried out among 160 participants in the Bathinda district. The questionnaire was distributed through online platforms. The self-made questionnaire was used to assess the level of awareness among the patients Results: The study assessed participants awareness of smokings effects on oral health, revealing varied levels of understanding. High awareness was noted for teeth staining, oral cancer risk, and decreased taste, while gaps existed regarding gum disease, second-hand smoke risks, and the role of dental visits in preventing smoking-related issues. Educational efforts are needed to address these gaps. Conclusion: The study reveals gaps in awareness of smokings serious oral health risks. Increased education and smoking cessation efforts are needed to improve patient outcomes.

Social Presence, Negative Emotions, and Self-Protective Behavioral Intentions of Nonsmokers in Response to Secondhand Smoking in Virtual Reality: Quasi-Experimental Design.

The application of virtual reality (VR) in health care has grown rapidly in China, where approximately half of the population is directly exposed to secondhand smoke (SHS). As VR headsets have become increasingly popular and short video platforms have incorporated 360° videos in China, new formats and opportunities for health campaigns about SHS have emerged. In a simulated environment of exposure to SHS, this study aims to explore the emotional and behavioral responses to enhanced social presence brought about by VR in contrast to flat-screen videos. It also aims to examine whether and to what extent video modality (360° video vs flat-screen video) and contextual cues (high threat vs low threat) influence psychometric and intentional variables among viewers. A total of 245 undergraduate and graduate students who were nonsmokers and from a large university in China participated in this study between October 2020 and January 2021. This study created 4 different versions of a SHS experience in a café with a 2 (360° video on a head-mounted display vs flat-screen display) × 2 (high threat vs low threat) experimental design. It developed and tested a path model examining the effects of experience modality and threat levels on social presence, emotions (anger and disgust), and eventually behavioral intentions (staying away and asking for help). We found that both video modality (P<.001) and threat level (P=.005) significantly influenced social presence, whereas the interaction of video modality and threat level did not have a statistically significant effect on social presence (P=.55). Negative emotions mediated the relationships between social presence and SHS-related self-protective behaviors. Specifically, anger positively predicted the intention to ask smokers to stop smoking through the waitress (P<.001). Disgust and fear both positively predicted the intention to stay away from the SHS environment (P<.001 for disgust; P=.002 for fear). This study explored the potential mediating mechanisms that influence individuals' responses to the risks of SHS in public areas. The results demonstrated that social presence and negative emotions are 2 important mediators that underlie the relationship between video modality and behavioral intention regarding SHS in a VR setting. These findings suggest that an immersive environment could be a better stimulator of anti-SHS emotions and behaviors than flat-screen videos.

The Intersection of Demographic Factors, Parental Awareness, and Attitudes: Implications for Children's Health Risks from Secondhand Tobacco Smoke

Objective: This study aims to investigate the association between demographic factors, such as age, ethnicity, income, education, and occupation, with parents' perspectives and awareness of the health risks associated with secondhand smoke (SHS), considering the significance of these factors for effective health education and prevention initiatives. Methods: Data were collected from 378 employees working in four higher education institutions in the Klang Valley region of Malaysia. A standardized questionnaire was administered to collect data on demographic characteristics, knowledge, and attitudes towards SHS. Path analysis was employed to examine the relationships between demographic characteristics and parents' knowledge of and attitudes towards the risks of SHS. Results: The study explored how demographic factors, namely age, education, occupation, income level, and ethnicity, influenced parents' knowledge and attitudes towards the health risks of SHS. The results indicated that none of these demographic characteristics had a significant impact on parents' attitudes and knowledge. However, it was observed that parents' financial status significantly and negatively affected their understanding of the health hazards associated with children's exposure to smoking. Conclusions: Protecting children's health and reducing the prevalence of smoking-related illnesses requires parents to enhance their knowledge and foster negative attitudes towards SHS. Developing targeted interventions that address the specific challenges parents face, particularly in relation to their financial circumstances, is crucial to promote a smoke-free environment for children. Research Implications: The study's findings provide insights into the complex relationship between demographic factors and parents' knowledge and attitudes towards SHS. These insights can inform the design of tailored interventions that consider various demographic characteristics to communicate SHS risks and promote healthier behaviours effectively. Originality/Value: This study contributes to the existing literature by examining the influence of demographic factors on parents' perspectives on SHS health risks. The findings underscore the importance of considering demographic characteristics when designing interventions to address SHS exposure and encourage healthier behaviours among parents and caregivers.

Understanding Second-hand Smoke (SHS) Exposure among University Students in Selangor and Perak, Malaysia: Role of Parents and Peers

Second-hand smoke (SHS) exposure remains a significant public health concern worldwide, posing various adverse effects on individual health during both short- and long-term exposures. University students in Malaysia are particularly at risk due to the potential influence of parents and peers on their SHS exposure. However, there is a lack of comprehensive research exploring the extent of this influence and its implications for effective intervention strategies. This cross-sectional study administered an online questionnaire to 387 students from two universities in Selangor and Perak. Prevalence rates of SHS exposure were determined, and factors associated with exposure were identified through descriptive and multivariable logistic regression analysis. Almost half (49.9%) of the participants had been exposed to SHS. Female students had a reduced risk of exposure by more than half compared to male students (p = 0.050). Meanwhile, those who had a smoking parent and smoking friends had approximately four times (p = 0.000) and two times (p = 0.002) the increased likelihood of being exposed to SHS, respectively, then those who did not. Participants with higher household income (p = 0.000) and higher mothers’ educational attainment (p = 0.028) had a significantly lower risk of SHS exposure. In conclusion, gender, parental smoking, peer smoking, and socioeconomic status were identified as factors associated with SHS exposure. Parental and peer awareness and understanding of SHS risk must be enhanced to minimise its exposure among their children and friends. Hence, health policymakers should address strategies such as ongoing public awareness campaigns, the extension of a smoking ban on advertising, promotion, and marketing of tobacco products, and rules for smoking prohibition at home to drive Malaysia’s effort towards a smoke-free generation.

Passive smoking as a risk factor among older adults: an ordered probability approach for Türkiye.

Older adults represent a significant proportion of the population of many societies, and being one of the disadvantaged groups, they struggle with various difficulties in their social lives. Undoubtedly, passive smoking is one of these difficulties. Passive smoking among older adults, which is an important public health problem, is an issue that needs to be investigated. The aim of this study is to determine the relationship between the demographic and socio-economic characteristics of adults aged 60 and older in Türkiye and their exposure to secondhand smoke (SHS). In this study, a microdata set of the 2016 and 2019 Turkey Health Survey conducted by the Turkish Statistical Institute (TUIK) was used. This survey was conducted by TUIK in the relevant years using a stratified sampling method to best represent the whole of Turkey. The study considered only demographic and socio-economic characteristics to investigate passive smoking. Since all the variables used in the study were categorical, the relationship between the dependent variable and the independent variables was first investigated using chi-square tests. In addition, since the dependent variable has an ordered-categorical probability form, the generalized ordinal logit model was used for the analysis of passive smoking and related factors. The rate of exposure to tobacco smoke of older adults who participated in the study in 2016 was 16%, while the rate of those who participated in the study in 2019 was 21%. According to the findings of the study, older, uneducated, and uninsured smokers carry a more serious SHS risk. It may be beneficial for society for policy makers to carry out studies by considering these features a priority and focusing on policies in this context. Expanding smoke-free areas to cover older adult, increasing penalties as a deterrent, facilitating education, increasing state support for education, increasing education and public service announcements about tobacco harms, and facilitating social security are the main examples. This study's findings are crucial as a source of information for the development of policies and programs aimed at preventing the exposure of older adults to tobacco smoke.

Social Media Data Mining of Antitobacco Campaign Messages: Machine Learning Analysis of Facebook Posts.

Social media platforms provide a valuable source of public health information, as one-third of US adults seek specific health information online. Many antitobacco campaigns have recognized such trends among youth and have shifted their advertising time and effort toward digital platforms. Timely evidence is needed to inform the adaptation of antitobacco campaigns to changing social media platforms. In this study, we conducted a content analysis of major antitobacco campaigns on Facebook using machine learning and natural language processing (NLP) methods, as well as a traditional approach, to investigate the factors that may influence effective antismoking information dissemination and user engagement. We collected 3515 posts and 28,125 associated comments from 7 large national and local antitobacco campaigns on Facebook between 2018 and 2021, including the Real Cost, Truth, CDC Tobacco Free (formally known as Tips from Former Smokers, where "CDC" refers to the Centers for Disease Control and Prevention), the Tobacco Prevention Toolkit, Behind the Haze VA, the Campaign for Tobacco-Free Kids, and Smoke Free US campaigns. NLP methods were used for content analysis, including parsimonious rule-based models for sentiment analysis and topic modeling. Logistic regression models were fitted to examine the relationship of antismoking message-framing strategies and viewer responses and engagement. We found that large campaigns from government and nonprofit organizations had more user engagements compared to local and smaller campaigns. Facebook users were more likely to engage in negatively framed campaign posts. Negative posts tended to receive more negative comments (odds ratio [OR] 1.40, 95% CI 1.20-1.65). Positively framed posts generated more negative comments (OR 1.41, 95% CI 1.19-1.66) as well as positive comments (OR 1.29, 95% CI 1.13-1.48). Our content analysis and topic modeling uncovered that the most popular campaign posts tended to be informational (ie, providing new information), where the key phrases included talking about harmful chemicals (n=43, 43%) as well as the risk to pets (n=17, 17%). Facebook users tend to engage more in antitobacco educational campaigns that are framed negatively. The most popular campaign posts are those providing new information, with key phrases and topics discussing harmful chemicals and risks of secondhand smoke for pets. Educational campaign designers can use such insights to increase the reach of antismoking campaigns and promote behavioral changes.

Quantifying Risk to Flight Attendants from Secondhand Smoke Exposure in Airline Cabins Using Pharmacokinetic Modeling: A Case Report

Background: Several studies of the health problems incurred by flight attendants flying during the smoking years concluded that they suffered elevated rates of chronic bronchitis, heart disease, skin cancer, breast cancer, melanoma, reproductive cancers, middle ear infections, hearing loss, asthma, pneumonia, chronic obstructive pulmonary disease, various pulmonary function abnormalities, plus depression and anxiety. Aims: Systematic review of secondhand smoke risks to flight attendants, exemplified using a specific case involving a deceased flight attendant who suffered from a multiplicity of tobacco-smoke-related diseases, including asthma, breast cancer, carotid artery stenosis, cataracts, cervical cancer, chronic obstructive pulmonary disease, coronary artery disease, laryngeal cancer, pneumonia and chronic myeloid leukemia. The decedent died in 2014 at age 68, losing an estimated 18.5 years of life expectancy. Methods: Pharmacokinetic modeling was used for the first time to estimate the risk from secondhand smoke for flight attendants on typical passenger aircraft flown by the decedent during an 18 year period ending in 1988. Results: Based on in-flight cotinine dosimetry measured in an Air Canada study, typical flight attendants would have inhaled a dose-equivalent of fine particle air pollution exceeding the “Air Pollution Emergency” levels of the U.S. Environmental Protection Agency’s Air Quality Index. The secondhand smoke cotinine dose for typical flight attendants in aircraft cabins is estimated to have been 6-fold that of the average US worker and 14-fold that of the average person. Thus, ventilation systems massively failed to control secondhand smoke air pollution in aircraft cabins, and led to extreme exposures. The decedent’s estimated lifetime cancer risk from secondhand smoke was 18 times U.S. OSHA’s Significant Risk of Material Impairment of Health level of 1 per 1000 per working lifetime. Conclusions: In-flight exposure to toxic and carcinogenic tobacco smoke in smoky passenger cabins was the major risk factor leading to the decedent’s multiple smoking-related diseases, and her premature death. This has implications for the extant and future health of the cohort of surviving flight attendants exposed to secondhand smoke on aircraft during the 20th Century Era.

Pregnant Women's Perception of Secondhand Smoke Exposure.

Birth outcomes including low birth weight, preterm birth, and delayed infant neurodevelopment are associated with secondhand smoke exposure while pregnant. The purpose of the study was to explore pregnant women's perspectives on secondhand smoke exposure to understand their experience and inform recommendations. Qualitative semistructured interviews were conducted with 15 secondhand smoke-exposed pregnant women in the United States. Four primary themes were identified: feeling powerless, trapped, and discomfort; enhancing women's self-advocacy and initiative; having conflicting feelings about secondhand smoke exposure; and desiring professional advice and education. Women expressed concern about prenatal secondhand smoke exposure, although they felt unable to request that people refrain from smoking in their presence or personal space. Women's strategies to minimize secondhand smoke exposure often involved their own social isolation. Women described sources of support, educational needs, and desire for practical advice in secondhand smoke avoidance. Findings underscore the role of nurses working with pregnant women living with household members who smoke to educate women about secondhand smoke risks and strategies for avoidance and to enhance women's self-confidence in advocating for themselves to reduce their exposure.

Cigarette smoking and quitting by individuals in Malaysia

ABSTRACT Objectives Understanding the sociodemographic characteristics associated with cigarette smoking and quitting decisions allows policy decision-making to attempt to curtail smoking. Individual smoking and quitting decisions are examined using an endogenous sample selection model. Methods Using data for 4,110 individuals from the 2011 Malaysian Global Adult Tobacco Survey, a probit model is estimated for quitting, subject to sample selection for smokers. Marginal effects of exposure variables are calculated for the probability of smoking and probability of quitting conditional on smoking. Results Ethnic Malays/Bumiputera, urbanites, ignorance of the hazards associated with secondhand smoke, lack of smoking rules at home, and lack of religious restriction contribute to smoking likelihoods. Older age, being a female, ethnic Chinese, married, at home smoking prohibition, and knowledge of secondhand smoke risks are associated with higher probability of quitting conditional upon smoking. Working in non-government occupations, individuals of other ethnic background, and smoking consent at home are associated with lower quitting probability conditional upon smoking. Conclusion Health awareness and educational programs should be directed at specific population groups with the above sociodemographic characteristics to discourage smoking initiation and promote quitting among smokers.

Real-time feedback of air quality in children's bedrooms reduces exposure to secondhand smoke.

INTRODUCTIONSecondhand smoke (SHS) exposure creates health risks for non-smokers and is especially detrimental to children. This study evaluated whether immediate feedback in response to poor indoor air quality in children’s bedrooms can reduce the potential for SHS exposure, as measured by adherence to a World Health Organization (WHO) indoor air standard.METHODSHomes that contained children and an adult who regularly smoked inside (n=298) had an air particle monitor installed in the child’s bedroom. These devices measured the concentration of particulate matter (PM2.5) for approximately three months and, for half of the participants, immediately provided aversive feedback in response to elevated PM2.5. Hierarchical linear models were fit to the data to assess whether the intervention increased the probability that: 1) a given day was below the WHO guideline for daily exposure, and 2) a household established and maintained a smoke-free home (SFH), operationalized as achieving 30 consecutive days below the WHO guideline. The intervention’s impact was calculated as group-by-time effects.RESULTSThe likelihood that a child’s bedroom met the WHO indoor air quality standard on a given day increased such that the baseline versus post-baseline odds ratio (OR) of maintaining indoor PM2.5 levels below the WHO guideline was 2.38 times larger for participants who received the intervention. Similarly, the baseline versus post-baseline OR associated with achieving an SFH was 3.49 times larger for participants in the intervention group.CONCLUSIONSThe real-time intervention successfully drove clinically meaningful changes in smoking behavior that mitigated indoor PM2.5 levels in children’s bedrooms and thereby reduced SHS exposure. These results demonstrate the effectiveness of targeting sensitive microenvironments by giving caregivers actionable information about children’s SHS risks. Future extensions should examine additional microenvironments and focus on identifying the potential for SHS exposure before it occurs.

Secondhand Aerosol Exposure From Heated Tobacco Products and Its Socioeconomic Inequalities in Japan: The JASTIS Study 2017-2020.

The growing use of heated tobacco products (HTPs) has raised concerns about secondhand aerosol (SHA) from HTPs, but few studies have been reported on it. This study aimed to investigate the trends in SHA exposure and their socioeconomic inequalities in Japan. The prevalence of SHA exposure from 2017 to 2020 was estimated using longitudinal internet survey data of 5221 participants, aged 20-69 years in 2017 (baseline), with adjustments using inverse probability weighting for "being a participant in an internet survey". Multivariable modified Poisson regression models were applied to examine the association between socioeconomic status (ie, educational attainment and equivalent income) at baseline and SHA exposure in 2020 with adjustments for sex and age. The estimated prevalence of SHA exposure has consistently increased from 4.5% in 2017 to 10.8% in 2020. Lower educational attainment was associated with a higher risk of SHA exposure (p for trend = 0.010). The covariate-adjusted risks of SHA exposure in participants with a low-education and middle-education level were 1.57 and 1.34 times higher, respectively, than in those with a high-education level. However, significant differences in risks of SHA exposure between participants with low-, middle-, and high-income levels were not observed. Meanwhile, participants with a low-education and middle-education level also had 1.87 and 1.61 times higher risks of secondhand smoke (SHS) exposure from combustible cigarettes than those with a high-education level, respectively. Our study revealed a rapid increase in SHA exposure and the existence of educational inequalities in both SHA and SHS exposure. Using longitudinal internet cohort survey data, we found that the prevalence of exposure to secondhand aerosol (SHA) from heated tobacco products (HTPs) rapidly increased to 10.8% in 2020 in Japan. Furthermore, people with lower educational attainment were at higher risk of SHA exposure, suggesting that extensive educational interventions may be necessary to inform the public that although emissions from HTPs contain significantly lesser amounts of harmful and potentially harmful constituents and these compounds than cigarette smoke, they are not harmless and still entail risks, and its long-term effects are unknown. Therefore, future extensive monitoring of SHA exposure is needed.

Egyptian HCPs’ awareness, attitudes and practice to SHS exposure among pregnant women and children

Abstract Background and aims Around half of Egyptian pregnant non-smoking women and children are exposed to secondhand smoke (SHS), which cause serious morbidities. Health care professionals (HCPs) are well placed to help reduce SHS exposure by encouraging avoiding SHS. This study aimed to explore risk-awareness, attitudes and practice of HCPs in relation to SHS exposure among pregnant women and children in Egypt. Methods Cross-sectional survey of HCPs working in public maternal and child health clinics in Assiut city, Egypt. The survey included questions on risk-awareness, attitudes and counselling practice. Descriptive and regression analysis was performed to explore factors associated with high risk-awareness, supportive attitudes, and good counselling practice. Results 367 HCPs participated in the survey with the majority being nurses (45%) and gynaecologists/obstetricians (21%). 12.5% of HCPs were smokers, and considerable proportion of HCPs reported being exposed to SHS at workplace (70.3%) and at home (51.7%). Just over half of all HCPs (55.9%) had high SHS risk awareness. Speciality, serving urban communities, and home SHS exposure were significantly associated with high-risk awareness. 52.9% of HCPs had supportive attitude towards preventing SHS exposure. Being female, serving rural communities, home SHS exposure were significantly associated with supportive attitudes. Only 51.8% of HCPs reported good counselling practice, which was explaining SHS hazards and advising to avoid it. Being female, serving rural communities, not exposed to SHS at home, and previous training on smoking cessation service were significantly associated with good counselling practice. Conclusions HCPs' awareness, attitudes and practice regarding the risks of SHS to pregnant women and children in Egypt are at low levels. Training is required for HCPs to improve their knowledge and skills and be able to help pregnant women and children to avoid SHS exposure and reduce consequent health burden. Key messages HCPs’ awareness and practice regarding risks of SHS to pregnant women/children in Egypt are inadequate. HCPs’ training is essential to help pregnant women/children to avoid SHS and reduce health burden.

Testing effects of awareness of statewide smoke-free air law and risk perception on smoking behaviors

PurposeTo reduce the smoking rates and alleviate societal problems associated with smoking, health administrators and policy makers have attempted to promote and implement statewide smoking free policy. The present study examined how adults' awareness of and attitude toward the smoke-free air law, their perceived risks of secondhand smoke and current smoking status were associated with smoking attitude and behaviors.Design/methodology/approachAs part of the Indiana Adult Tobacco Survey, 2,027 respondents participated in cross-sectional telephone surveys. A series of independent sample t-test and binary logistic regression analyses were performed.FindingsAwareness of the state law was inversely related to negative attitude toward smoking behaviors. Individuals who reported favorable attitude toward the state smoke-free air law and higher risk perceptions of secondhand smoke showed negative attitude toward smoking behaviors. Non-smokers and former smokers were significantly different from current smokers with regard to attitude toward smoking. Negative attitude was significantly related to intention to quit smoking. Awareness of the state law, perceived risk and current smoking status were key determinants for anti-smoking attitude and behavior.Originality/valueFindings highlight the importance of effective dissemination of the state law and recommend a strategic intervention design that invokes risk perceptions of secondhand smoke.

Levels and factors of knowledge about the related health risks of exposure to secondhand smoke among medical students: A cross-sectional study in Jeddah, Saudi Arabia.

INTRODUCTIONSecondhand smoke (SHS) appears to be an insidious public health issue in Saudi Arabia, with a high percentage of people being reportedly exposed. In an attempt to raise awareness about this issue, we explored medical students’ level of knowledge about SHS risks, as well as their levels of exposure to SHS and the correlation between knowledge and exposure.METHODSA cross-sectional study was conducted in February 2020 at the Faculty of Medicine, King Abdulaziz University, Jeddah, Saudi Arabia. An online, modified version of a validated questionnaire was distributed among 2nd to 6th year medical students. The questionnaire mainly explored the following items: 1) exposure level to SHS; 2) impact of SHS exposure; and 3) knowledge about SHS related health risks, with calculation of a knowledge score (range: 0–8). Adequate knowledge was defined as a score ≥5 (median = 5), and associations with sociodemographic and lifestyle factors and exposure to SHS were analyzed using chi-squared and independent t-test, as appropriate.RESULTSOf a total 416 participants, 65.0% declared having one or more smoking persons among acquaintances, 26.4% being exposed to SHS at home, and 40.1% exposed to parental smoking during childhood. Further, 79.8% reported being regularly exposed to SHS in public places. Majority of participants reported significant discomfort (53.2%) and physical symptoms (98.3%) subsequent to SHS exposure. Among the list of 8 health risks, ear infection in children (28.1%), heart attack in children (37.5%), and cognitive deficit (47.8%) were the least frequently identified. Adequate knowledge was found among 57.5% of the participants, and was higher among females and lower among participants living with their friends, compared to their counterparts (p<0.05). No association of knowledge level was observed with the parameters of exposure to SHS and poor discomfort feeling.CONCLUSIONSThe level of knowledge of medical students about health risks related to passive smoking is inadequate, while their exposure to SHS in public places is still substantial. This urges for the reinforcement of tobacco control strategies and highlights the great interest for medical colleges to implement effective educational interventions by improving their curricula regarding the risks of SHS and the benefits of smoking cessation.

Secondhand Smoke Risk Communication: Effects on Parent Smokers’ Perceptions and Intentions

This study examined effective strategies to communicate with parent smokers about the risks of secondhand smoke (SHS) exposure to children. An online, between-subjects experimental survey was administered via TurkPrime Panels to recruit participants (N = 623) comprising adult smokers living with children (aged 0–15). Participants were assigned to messages conditions that differed by message recommendation (cessation; cessation+exposure reduction) and format (video; text-only) or to a no-message control. Participants in a message condition viewed a message, and all participants responded to questions about their perceptions and intentions. Parent smokers who viewed either message recommendation reported greater harm perceptions (p <.001), self-efficacy (p <.001), and help-seeking intentions (p <.05) than the no-message control group. Cessation+exposure reduction recommendations elicited greater quit intentions than the no-message control (p <.05). Compared to text-only, videos elicited greater reduce-exposure intentions (p <.05) and interpersonal communication intentions (p <.05). Only videos elicited greater quit intentions (p <.01) and help-seeking intentions (p <.01) than the no-message control. Communication about this topic can be optimized by recommending both cessation and exposure-reduction behaviors (versus cessation only), and by using videos (versus traditional print/text-based materials).

Stigma and Smoking in the Home: Parents' Accounts of Using Nicotine Replacement Therapy to Protect Their Children from Second-Hand Smoke.

Evidence and campaigns highlighting smoking and second-hand smoke risks have significantly reduced smoking prevalence and denormalised smoking in the home in Scotland. However, smoking prevalence remains disproportionally high in socioeconomically disadvantaged groups. Using stigma as a theoretical lens, this article presents a thematic analysis of parents’ accounts of attempting to abstain from smoking at home, using nicotine replacement therapy (NRT), in disadvantaged areas of Edinburgh and the Lothians. Smoking stigma, particularly self-stigma, underpinned accounts, with two overarching themes: interplaying barriers and enablers for creation of a smoke-free home and reconceptualisation of the study as an opportunity to quit smoking. Personal motivation to abstain or stop smoking empowered participants to reduce or quit smoking to resist stigma. For those struggling to believe in their ability to stop smoking, stigma led to negative self-labelling. Previously hidden smoking in the home gradually emerged in accounts, suggesting that parents may fear disclosure of smoking in the home in societies where smoking stigma exists. This study suggests that stigma may act both as an enabler and barrier in this group. Reductions in smoking in the home were dependent on self-efficacy and motivations to abstain, and stigma was entwined in these beliefs.

'They only smoke in the house when I'm not in': understanding the limited effectiveness of a smoke-free homes intervention.

BackgroundChildren’s second-hand smoke (SHS) exposure in the home is highest in socio-economically disadvantaged areas. Personalized household air-quality measurements can promote changes in smoking that reduce SHS exposure. The ‘First Steps 2 Smoke-free’ (FS2SF) intervention is the first to trial this approach delivered as part of health professionals’ routine work. This paper reports the findings of qualitative interviews with participants that explored their experiences of the intervention and why outcomes varied.Methods120 women were recruited from the NHS First Steps Programme, which supports disadvantaged mothers. They received either personalized feedback on their home air quality and advice on reducing SHS or standard SHS advice. Qualitative interviews with 15 mothers were analyzed thematically using the Capability, Opportunity, Motivation, Behaviour (COM-B) model.ResultsThe intervention increased women’s capability to change home-smoking behaviour, through increasing awareness and salience of SHS risks to their children, and motivation to act. However, taking effective action was constrained by their limited social and environmental opportunities, including others’ smoking in the home.ConclusionsThe FS2SF intervention was ineffective as it was unable to fully address the precarious, complex life circumstances that make creating a smoke-free home particularly difficult for women experiencing intersecting dimensions of disadvantage.

Relation of secondhand smoke exposure to vascular phenotypes in children and adolescents.

INTRODUCTIONSubclinical cardiovascular risks of secondhand smoke (SHS) exposure among children and adolescents remains insufficiently described.METHODSThis was a cross-sectional study of 298 children and adolescents (48.0% male, body mass index: 27.0±8.9kg/m2), including 49 self-reported cases with SHS. Arterial elasticity and stiffness (distensibility, compliance, incremental elastic modulus [IEM]) were obtained via ultrasound imaging in the abdominal aorta, brachial, and carotid arteries. A one-way analysis of variance compared differences between groups, and multiple linear regression adjusted for covariates.RESULTSSHS was associated with lower abdominal aorta diameter distensibility (aDD) (13.4±3.6% vs. 16.0±5.2%, p=0.009), and abdominal aorta cross-sectional distensibility (aCSD) (28.8±8.3% vs. 35.1±12.2% p=0.009), as well as higher abdominal aorta IEM (aIEM) (1241±794mmHg vs. 935±388mmHg, p=0.001). After adjustment for covariates, aDD (p=0.047), aCSD (p=0.040), and aIEM (p=0.017) remained significant; this significance persisted with the additional adjustment of percent body fat. Measures of brachial and carotid compliance and distensibility were not associated with SHS.CONCLUSIONSSHS was associated with abdominal aorta stiffness; the majority of vascular measures within the brachial and carotid artery remained unaffected following adjustment for covariates, including hypertension and adiposity. SHS may predispose individuals to increased abdominal aorta stiffness, an artery previously reported to exhibit increased susceptibility to atherosclerosis.

Exposure to secondhand smoke in vehicles among Canadian adolescents: Years after the adoption of smoke-free car laws

Exposure to secondhand smoke (SHS) can result in several adverse health consequences. SHS concentrations in vehicles can significantly exceed levels present in other enclosed spaces. Years after the adoption of smoke-free car laws, this study examined the prevalence of exposure to SHS in vehicles among adolescents. Data were utilized from the 2016–2017 Canadian Student Tobacco, Alcohol and Drugs Survey (n = 48,444). The prevalence of exposure to SHS in cars was estimated by grade level and demographic characteristics. The results showed a gradient by grade level in exposure to SHS with students in upper-grade levels reporting a higher prevalence of SHS in cars. SHS varied by province, with the lowest rate found in British Columbia (15.6%) and the highest in Saskatchewan (36.9%). The provinces with laws that extend protections to older children also had high rates of SHS exposure among students in upper-grade levels. Students exposed to SHS were more likely to engage in risky behaviors, including the use of marijuana, alcohol, cigarettes, and e-cigarettes. Despite laws prohibiting smoking in vehicles carrying children, SHS prevalence remains high. While enforcement of these laws may be challenging, persuasion campaigns highlighting that children are especially vulnerable to the health risks of SHS may be beneficial.

The impact of flavors, health risks, secondhand smoke and prices on young adults' cigarette and e-cigarette choices: a discrete choice experiment.

To estimate young adults' preferences for cigarettes and e-cigarettes, and how preferences vary by policy-relevant factors. A related aim was to provide information on potential substitution/complementarity across cigarettes and e-cigarettes ahead of policy selection. An online discrete choice experiment (DCE) in which respondents chose their preferred option among cigarettes, two types of e-cigarettes (disposable/reusable) and 'none'. Each cigarette-type was characterized by policy-relevant attributes: flavors, short-term health risks to self, secondhand smoke risks and price. A latent class model identified smoking types that respond differently to these. US tobacco market. A total of 2003 young adults (aged 18-22years) who ever tried either cigarettes or e-cigarettes, recruited via the survey platform Qualtrics, matched to the 2015 National Health Interview Survey by age, gender, education and census region. Respondents' DCE choices. Young adults fell into two broad categories. One latent group, termed 'prefer smoking group', preferred cigarettes and another, 'prefer vaping group', preferred e-cigarettes. The 'prefer smoking group' preferred lower prices and lower health harms more than other attributes. The 'prefer vaping group' valued these, although price less intensely, and valued health and fruit/candy flavors more. Banning all flavors in cigarettes and e-cigarettes might improve the health of young adults who ever tried either cigarettes or e-cigarettes. Young adult ever-triers might be deterred from smoking by increasing cigarette prices and encouraged to switch to e-cigarettes by reducing the health harms of e-cigarettes. Reducing health harms of e-cigarettes could also make the 'prefer vaping group' less likely to quit, resulting in increased health harm.
