Dietary Patterns among Smokers and Non-Smokers: Findings from the National Health and Nutritional Examination Survey (NHANES) 2017-2018. Nutrients 2024; 16:2035. [PMID: 38999783 PMCID: PMC11243715 DOI: 10.3390/nu16132035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/30/2024] [Revised: 06/24/2024] [Accepted: 06/25/2024] [Indexed: 07/14/2024] Open
Abstract
Diet behavior and nutrition are critical for maintaining health and improving quality of life. Cigarette smoking remains the leading cause of preventable death in the United States. Poor dietary choices, such as excessively frequenting restaurants, consuming ready-to-eat foods from grocery stores, and ingesting ultra-processed foods (like frozen meals and pizzas), can adversely impact health. Despite this, research comparing dietary behaviors between smokers and non-smokers is limited. Using data from the National Health and Nutritional Examination Survey 2017-2018, we analyzed diet behavior based on smoking status. Our findings reveal that smokers had a significant increase (90%) in the frequency of consuming frozen meals/pizzas in the past 30 days compared to non-smokers (coefficient: 1.9; 95% CI: 1.4, 2.6; p-value < 0.001). Additionally, over 70% of participants, regardless of their smoking status, were unaware of MyPlate, a nutritional guide created by the United States Department of Agriculture (USDA) to encourage Americans to make healthier food choices. There is an urgent need to increase public awareness of MyPlate and promote a better understanding of healthy dietary behaviors.

Lin W. The Association between Body Mass Index and Glycohemoglobin (HbA1c) in the US Population's Diabetes Status. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2024; 21:517. [PMID: 38791732 PMCID: PMC11121031 DOI: 10.3390/ijerph21050517] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/05/2024] [Revised: 04/19/2024] [Accepted: 04/19/2024] [Indexed: 05/26/2024]
Abstract
Obesity, indicated by Body Mass Index (BMI), is a risk factor for type 2 diabetes. However, its association with glycated hemoglobin (HbA1c), a crucial indicator of blood-sugar control, may vary across different populations and disease statuses. Data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 were analyzed. Participants aged 18-79 years with complete information on BMI, diabetes status, and HbA1c were included (n = 4003). Linear regression models were used to assess the association between BMI and HbA1c, adjusting for demographic confounders, smoking status, alcohol consumption, and healthcare access. Among participants without diabetes, BMI was positively associated with HbA1c levels (coefficient: 0.015, 95% CI: 0.01, 0.02; p-value < 0.05), after adjusting for potential confounders. However, this association was not significant among those with diabetes (coefficient: -0.005, 95% CI: -0.05, 0.04; p-value > 0.1). Our findings suggest a differential relationship between BMI and HbA1c in individuals with and without diabetes. While BMI remains a significant predictor of HbA1c in non-diabetic individuals, its significance diminishes in those with diabetes.

Abstract
INTRODUCTION Patient-provider communication quality is instrumental for healthy outcomes in patients. The objective of this study is to examine the relationships between patient-provider communication quality and participant characteristics, perception of e-cigarette harmfulness, and smoking outcomes. METHODS A pooled cross-sectional design was used on secondary data obtained from the Health Information National Trends Survey (HINTS) 5 from Cycle 1 through Cycle 4, from 2017-2022. Our final sample contained 3511 observations. Our outcome variable was the perception of electronic cigarette smoking status. The independent variable was patient-provider communication quality (PPCQ), measured from a series of questions with responses on a 4-item Likert scale (always, usually, sometimes, never). Demographic variables such as marital status, health insurance status, occupation status, and health-related variables were used as participant characteristics. Ordinal logistic regression models were used to examine the above relationships. RESULTS Compared to males, females had lower odds of being in a higher category of perception of e-cigarette harmfulness compared to other categories of e-cigarette harmfulness (AOR=0.66; 95% CI: 0.57-0.76). Respondents who were non-Hispanic Black or Hispanic had lower odds of being in a higher category of perception of e-cigarettes compared to Whites (AOR=0.52; 95% CI: 0.49-0.78, and AOR=0.51; 95% CI: 0.41-0.65, respectively). Respondents who had higher education level compared to those with less than high school had lower odds (AOR=0.30; 95% CI: 0.17-0.51), and Hispanics compared to Whites had higher odds (AOR=1.59; 95% CI: 1.05-2.40), of being former smokers rather than current smokers. CONCLUSIONS Providers should invest in staff training and development to target the populations that need conversations regarding e-cigarette usage.

Abstract
Cigarette smokers face greater challenges in accessing healthcare compared with non-smokers. In the US, approximately 2.2 million individuals are chronically infected with hepatitis B virus (HBV). I used data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018 to investigate the association between smoking status (current, former, and never smoker) and different health outcomes, including healthcare accessibility, HBV vaccination, general health condition, and health insurance. Multivariable logistic regressions were used to analyze healthcare disparity by smoking status. I found that current smokers had 40% higher odds (AOR = 1.4, 95% CI: 1.1, 1.8) of lacking routine healthcare access compared with non-smokers. Regardless of smoking status, I observed a high rate of HBV non-vaccination among all participants. Specifically, 64% of current smokers, 67% of former smokers, and 57% of non-smokers had not received a single dose of HBV immunization. My study sheds light on the persisting gaps in healthcare access, particularly for smokers, and the urgent need to promote awareness and vaccination against hepatitis B.

Varenicline for smoking cessation in individuals who smoke cigarettes and use electronic cigarettes: a double-blind, randomised, placebo-controlled phase 3 trial. EClinicalMedicine 2023; 66:102316. [PMID: 38192585 PMCID: PMC10772233 DOI: 10.1016/j.eclinm.2023.102316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/03/2023] [Revised: 10/24/2023] [Accepted: 10/30/2023] [Indexed: 01/10/2024] Open
Abstract
Background The efficacy and safety of varenicline for smoking cessation among individuals who smoke tobacco cigarettes and also use electronic cigarettes (known e-cigarettes or vapes) have not been studied. We aimed to address this knowledge gap and examine predictors for smoking abstinence. Methods In this double-blind, placebo-controlled, single-centre randomised trial in Italy, we enrolled adults who had used an e-cigarette daily for at least 12 months and who also smoked at least one tobacco cigarette per day and had a willingness to quit smoking. 155 participants were randomly assigned to receive either varenicline (n = 78) or matched placebo (n = 77). Varenicline (1 mg, administered twice daily for 12 weeks) was given in combination with smoking cessation counseling in dual users with an intention to quit smoking. Participants in both treatment groups received the same smoking cessation counselling throughout the whole duration of the study. The trial consisted of a 12-week treatment phase followed by a 12-week follow-up. The primary efficacy endpoint was continuous abstinence rate (CAR) in weeks 4-12. Secondary efficacy endpoints were the CAR in weeks 4-24 and 7-day point prevalence of smoking abstinence at weeks 12 and 24. This study is registered in EUDRACT, 2016-000339-42. Findings Between November 2018, and February 2020, 114 participants (61 in the varenicline group and 53 in the placebo group) completed the intervention phase at week 12 and 88 participants (52 in the varenicline group and 36 in the placebo group) completed the follow-up phase at week 24. CARs were significantly higher for the varenicline vs placebo at each time-point: 50.0% vs 16.9% (OR = 4.9; 95% CI, 2.3-10.4; P < 0.0001) between weeks 4 and 12; and 48.7% vs 14.3% (OR = 5.7; 95% CI, 2.6-12.3; P < 0.0001) between weeks 4 and 24. The 7-day point prevalence of smoking abstinence was also higher for the varenicline than placebo at each time point. Adverse events were rated as mild or moderate and rarely led to treatment discontinuation. Interpretation Our findings indicate that inclusion of varenicline in a cessation programme for adults who smoke and use e-cigarettes with an intention to quit smoking could result in smoking abstinence without serious adverse events. In the absence of evidence from other smoking cessation methods, it could be useful to suggest the use of varenicline in cessation programmes specifically designed to help dual users stop smoking. Further research in larger and more generalisable populations is required to strengthen such a suggestion.

Abstract
OBJECTIVE The aim of this study was to assess and compare knowledge of the health consequences of heavy alcohol consumption among individuals with different substance use statuses. METHODS We used a cross-sectional study design to analyze the Health Information National Trends Survey (HINTS) 5, Cycle 3 (2019). Participants were classified into four categories based on their substance use status: (a) nonsmoker and nondrinkers; (b) nonsmokers but drinkers; (c) smokers but nondrinkers; and (d) smokers and drinkers. Weighted logistic regression models were utilized to evaluate the association between knowledge of heavy alcohol consumption and health conditions by participants' substance use status. RESULTS More than 79% of participants were aware that drinking too much alcohol causes liver disease. However, less than 40% of them realized that heavy alcohol consumption also contributes to cancer. The odds of correctly identifying heavy alcohol consumption as a risk factor for diabetes were 3.00 times (95% confidence interval (CI): 1.29,7.00) higher among smokers but nondrinkers than smokers and alcohol drinkers. Education level was significantly associated with participants' awareness of risk factor (p < 0.01). DISCUSSION There is an urgent need for targeted educational campaigns and interventions to increase understanding of the impact of heavy alcohol consumption on cancer risk.

Abstract
Waterpipe tobacco smoking is a public health concern that poses many of the same health risks as cigarette smoking, especially among young adults-a subpopulation characterized by the highest prevalence of waterpipe tobacco smoking. Nevertheless, it remains understudied relative to other forms of tobacco use. We examined sociodemographic, behavioral and cognitive factors associated with young adults' motivation to quit waterpipe smoking using a theory-informed approach. We completed a secondary analysis of baseline data on waterpipe tobacco smoking beliefs and behavior collected from 349 US young adults aged 18-30 years. We analyzed sociodemographics, tobacco use and cessation behaviors and perceptions, and theory-related constructs associated with motivation to quit waterpipe tobacco smoking using linear regression. Overall, participants reported low motivation (mean = 2.68, SD = 1.56, scale range 1-7) and high self-efficacy (mean = 5.12, SD = 1.79) to quit waterpipe tobacco smoking. In multivariable analysis, prior quit attempts (β = 1.10, P < 0.01), greater perceived risks of waterpipe tobacco smoking (β = 0.42, P < 0.01) and increasingly negative attitudes toward waterpipe tobacco smoking (β = 0.29, P < 0.01) were associated with higher motivation to quit. These findings highlight the importance of those factors as potential cessation determinants. These findings can help guide the development and refinement of interventions targeting young adult waterpipe tobacco smoking.

Abstract
INTRODUCTION The objective of this study was to investigate the differences in urine concentrations of heavy metals (uranium, cadmium, and lead) between exclusive menthol and non-menthol cigarette smokers across three racial/ethnic groups using data from the National Health and Nutrition Examination Survey (NHANES) 2015-2016 Special Sample. METHODS Data from NHANES 2015-2016 Special Sample were analyzed to assess the association between menthol smoking and heavy metal biomarkers in urine across three racial/ethnic groups (N=351), including Non-Hispanic White (NHW), Non-Hispanic Black (NHB), and Hispanic/Other (HISPO). Multivariable linear regression models were used to estimate adjusted geometric means (GMs) and ratio of GMs (menthol/non-menthol smokers) (RGMs) for urine biomarkers of heavy metals between menthol and non-menthol smokers by race/ethnicity. RESULTS Among the 351 eligible participants, 34.4% (n=121) were NHW, 33.6% (n=118) were NHB, and 32.0% (n=112) were HISPO exclusive cigarette smokers. The analysis revealed significantly higher concentrations of urine uranium in NHB menthol smokers compared to NHB non-menthol smokers (RGMs=1.3; 95% CI: 1.0-1.6; p=0.04). NHW menthol smokers appeared to have higher levels of urine uranium than non-menthol smokers, but the difference was not statistically significant (9.0 vs 6.3; RGMs=1.4; 95% CI: 1.0-2.2; p=0.08). There were no significant differences in urine metals (cadmium and lead) by menthol status among NHW, NHB, or HISPO cigarette smokers (p>0.05). CONCLUSIONS The research findings regarding the higher levels of urine uranium among Non-Hispanic Black (NHB) menthol cigarette smokers raise questions about the claims suggesting that additives in cigarettes do not contribute to increased toxicity.

Abstract
BACKGROUND The study aims to explore the association between cigarette smoking with blood exposure to volatile organic compounds using population data from the National Health and Nutrition Examination Survey (NHANES) 2017-2018. METHODS Based on the data of NHANES 2017-2018, we identified 1117 participants aged 18 to 65 years, who had complete VOCs testing data and filled out the Smoking-Cigarette Use and Volatile Toxicant questionnaires. The participants consisted of 214 dual-smoking persons, 41 E-cigarette smokers, 293 combustible-cigarette smokers and 569 non-smokers. We used One-way ANOVA and Welch's ANOVA to compare differences of VOCs concentration among 4 groups and multivariable regression model to confirm the factors associated with VOCs concentration. RESULTS In dual-smoking and combustible-cigarette smokers, blood concentration of 2,5-Dimethylfuran, Benzene, Benzonitrile, Furan, Isobutyronitrile were higher than non-smokers. When compared with people who never smoked, E-cigarette smokers had similar blood concentrations of VOCs. Blood concentrations of Benzene, Furan, and Isobutyronitrile were significant higher in combustible-cigarette smokers than in E-cigarette smokers. In the multivariable regression model, dual-smoking and combustible-cigarette smoking were associated with elevated blood concentrations of several VOCs except 1,4-Dichlorobenzene, while E-cigarette smoking was only associated with elevated 2,5-Dimethylfuran concentration. CONCLUSIONS Smoking, mainly dual-smoking and combustible-cigarette smoking, is associated with elevated blood concentration of VOCs, while the effect is weak in E-cigarette smoking.

Abstract
Many adults express interest in e-cigarette cessation; however, there are few empirically tested interventions for quitting vaping. This study seeks to (1) evaluate reasons for quitting e-cigarettes in treatment-seeking adults, and (2) assess the feasibility and acceptability of nicotine replacement therapy (NRT) for e-cigarette cessation. Adult daily e-cigarette users completed qualitative interviews about quitting e-cigarettes, then were randomized to either 28-day supply of combination NRT (21 mg patches, 4 mg lozenges) + supportive booklet or Quitline referral. Primary aims were feasibility (number who enrolled) and acceptability (NRT use, adverse side effects). Exploratory aims evaluated abstinence (7-day point-prevalence) at end of treatment. Of the 30 participants who were enrolled, 50 % (n = 15) were dual users, and 50 % (n = 15) were mono-vapers, 26.6 % (n = 8) of whom were former smokers. Participants reported seeking treatment due to health concerns, dependence, stigma, and cost. Anticipated challenges of quitting vaping were withdrawal, negative mood, sensorimotor habits, and convenience. Most completed the end of treatment survey (n = 24; 80 %). Participants who received NRT reported using the patch M = 10.89 days and lozenges M = 6.39 days, with few days of adverse effects (M = 2.67). At end of treatment, 6/18 (33.3 %; 6 mono and 0 dual users) in the intervention group reported abstinence from vaping, compared to 0 in the control group (Fisher = 5.00, p =.057). In conclusion, adults are interested in quitting e-cigarettes due to negative consequences of use and are willing to use pharmacotherapy. Future research should confirm these results in a larger trial, address cigarette smoking in dual users, and aim to disseminate treatments.

Abstract
Introduction Tobacco use remains a global public health challenge. While studies report that smoking cessation reduces the risk of cancer and other NCDs, evidence is scarce in African region on socio-economic determinants of smoking cessation behavior. This study examined the socio-economic differentials of smoking cessation behavior among smokers in four African countries. Methods The study was conducted through secondary analysis of Global Adult Tobacco Survey (GATS) data from four African countries (Ethiopia, Kenya, Senegal and Tanzania). Smoking cessation behavior was assessed using two variables i) intention to quit smoking in next 12 months and ii) previous quit attempts made within 12 months preceding the survey. The weighted percentages for intention to quit smoking and previous quit attempts were computed. The adjusted odds ratios were computed using multinomial logistic regression to identify the association between socio-economic factors and smoking cessation behavior. Results Across the four countries studied, the previous quit attempts among smokers were in the range of 39.6% to 53.7%. Around 7.6% to 15.8% of the smokers tried to quit with an assistance. In Ethiopia over 76.5% of current smokers reported no intention to quit in next 12 months after survey, whereas the same was 50.4% in Senegal. While country specific differences were observed, females, those belonging to the poorest wealth index, unemployed and those without any formal education reported significantly lower odds of previous quit attempts or having an intention to quit smoking. Conclusion The socio-economic vulnerabilities were found to compromise smoking cessation behavior among the smokers in countries studied. Targeted interventions, adherence to smokefree laws, and provision of cessation support are essential to improve quit rates and mitigate tobacco risks among socio-economically vulnerable population.

Cancer Prev Res (Phila) 2022; 15:569-580. [PMID: 35816038 PMCID: PMC9444997 DOI: 10.1158/1940-6207.capr-22-0172] [Citation(s) in RCA: 15] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Revised: 06/01/2022] [Accepted: 07/05/2022] [Indexed: 11/16/2022]
Abstract
E-cigarette use has been increasing globally over the past decade. Many use e-cigarettes as an alternative or method to quit cigarette smoking, whereas others use these products recreationally. As technology has advanced, many individuals have reported symptoms of dependence on these products and continue to use them beyond achieving abstinence from smoking. Despite individuals reporting interest in quitting, little is known about e-cigarette cessation. This systematic review sought to identify and evaluate all human subjects literature published on the outcome of e-cigarette cessation through September 2021. Of the 79 articles identified, 56 were cross-sectional, 6 were qualitative, 5 were cohort studies, 3 were experimental, 2 were mixed methods, and 7 reported intervention or case studies of e-cigarette cessation. Results showed youth generally had high intent to quit e-cigarettes, whereas results were mixed with adult samples. Youth were motivated to quit e-cigarettes by health concerns, whereas adults were motivated to quit e-cigarettes by cost, lack of satisfaction, and psychologic factors. Adults were more likely to report past e-cigarette quit attempts, most commonly "cold turkey." Few interventions tested strategies for e-cigarette cessation, with a majority targeted for youth. Given the lack of information on e-cigarette cessation, recommendations for future studies are outlined.

Abstract
INTRODUCTION One-third of adults in the United States who use tobacco regularly use two or more types of tobacco products. As the use of e-cigarettes and other noncombusted tobacco products increases-making multiple tobacco product (MTP) use increasingly common-it is essential to evaluate the complex factors that affect product use. AIMS AND METHODS In this update to our 2019 conceptual framework, we review and evaluate recent literature and expand the model to include ways in which MTP use may be affected by market factors such as the introduction of new products and socioenvironmental factors like marketing and advertising. RESULTS AND CONCLUSIONS MTP use patterns are complex, dynamic, and multiply determined by factors at the level of individuals, products, situations or contexts, and marketplace. Substitution, or using one product with the intent of decreasing use of another, and complementarity, or using multiple products for different reasons or purposes, explain patterns in MTP use. Moreover, substitution and complementarity may inform our understanding of how market changes targeted at one product, for instance, new product standards, bans, product pricing, and taxation, affect consumption of other tobacco products. New data from natural experiments and novel laboratory-based techniques add additional data and expand the framework. IMPLICATIONS A substantial proportion of people who use tobacco use more than one product. This review synthesizes and evaluates recent evidence on the diverse factors that affect MTP use in addition to expanding our framework. Our review is accompanied by suggested research questions that can guide future study.

Abstract
Flavored cigar restrictions have the potential to benefit public health. Flavor availability facilitates cigarillo use, but it is unknown if flavor impacts patterns of co-use of cigarillos and cannabis, an increasingly prevalent behavior among young adults. Data were collected (2020-2021) in a cross-sectional online survey administered to a convenience sample of young adults who smoked cigarillos from 15 areas with high cigar use prevalence. We assessed the relationship between flavored cigarillo use and motivation to quit cannabis and cigarillo use among past 30-day co-users (N = 218), as well as several covariates (e.g., cigarillo price and flavor/cannabis policy). Flavored cigarillo perceived appeal and harm were hypothesized parallel mediators. Most co-users reported usually using flavored cigarillos (79.5%), which was not significantly associated with motivation to quit cigarillos or cannabis. Perceived cigarillo harm (β = 0.17, 95% CI = 0.00, 0.33), advertising exposure (β = 0.12, 95% CI = 0.00, 0.24), and income (among racial/ethnic minorities; β = -0.13, 95% CI = -0.25, -0.02) were significant predictors of motivation to quit cigarillos. There were no significant predictors of motivation to quit cannabis. Cigarillo flavor was not associated with motivation to quit, so findings could suggest that banning flavors in cigars may have a neutral impact on co-use with cannabis among young adults.

Electronic Cigarette Use Promotes a Unique Periodontal Microbiome. mBio 2022; 13:e0007522. [PMID: 35189698 PMCID: PMC8903898 DOI: 10.1128/mbio.00075-22] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 01/28/2022] [Indexed: 12/15/2022] Open
Abstract
Electronic cigarettes (e-cigs) have become prevalent as an alternative to conventional cigarette smoking, particularly in youth. E-cig aerosols contain unique chemicals which alter the oral microbiome and promote dysbiosis in ways we are just beginning to investigate. We conducted a 6-month longitudinal study involving 84 subjects who were either e-cig users, conventional smokers, or nonsmokers. Periodontal condition, cytokine levels, and subgingival microbial community composition were assessed, with periodontal, clinical, and cytokine measures reflecting cohort habit and positively correlating with pathogenic taxa (e.g., Treponema, Saccharibacteria, and Porphyromonas). α-Diversity increased similarly across cohorts longitudinally, yet each cohort maintained a unique microbiome. The e-cig microbiome shared many characteristics with the microbiome of conventional smokers and some with nonsmokers, yet it maintained a unique subgingival microbial community enriched in Fusobacterium and Bacteroidales (G-2). Our data suggest that e-cig use promotes a unique periodontal microbiome, existing as a stable heterogeneous state between those of conventional smokers and nonsmokers and presenting unique oral health challenges. IMPORTANCE Electronic cigarette (e-cig) use is gaining in popularity and is often perceived as a healthier alternative to conventional smoking. Yet there is little evidence of the effects of long-term use of e-cigs on oral health. Conventional cigarette smoking is a prominent risk factor for the development of periodontitis, an oral disease affecting nearly half of adults over 30 years of age in the United States. Periodontitis is initiated through a disturbance in the microbial biofilm communities inhabiting the unique space between teeth and gingival tissues. This disturbance instigates host inflammatory and immune responses and, if left untreated, leads to tooth and bone loss and systemic diseases. We found that the e-cig user's periodontal microbiome is unique, eliciting unique host responses. Yet some similarities to the microbiomes of both conventional smokers and nonsmokers exist, with strikingly more in common with that of cigarette smokers, suggesting that there is a unique periodontal risk associated with e-cig use.

Abstract
Background This study examined whether exposure to misinformation found on Twitter about e-cigarette harms leads to inaccurate knowledge and misperceptions of harms of e-cigarette use among cigarette smokers. Methods We conducted an online randomized controlled experiment in November 2019 among an online sample of 2400 adult US and UK cigarette smokers who did not currently use e-cigarettes. Participants viewed four tweets in one of four conditions: 1) e-cigarettes are as or more harmful than smoking, 2) e-cigarettes are completely harmless, 3) e-cigarette harms are uncertain and 4) control (physical activity). Outcomes were knowledge about e-cigarettes and harm perceptions of e-cigarette use for five diseases. We conducted multiple logistic and linear regressions to analyze the effect of experimental conditions on outcomes, controlling for baseline knowledge and perceived harms. Findings Participants in the ‘as or more harmful’ condition (vs. control group) had higher odds of accurate knowledge about e-cigarettes containing toxic chemicals ( p < 0.001), not containing only water vapor (p < 0.001) and containing formaldehyde ( p < 0.001). However, these participants had lower odds of accurate knowledge that e-cigarettes did not contain tar ( p < 0.001) and contained fewer toxins than cigarettes ( p < 0.001). Exposure to ‘as or more harmful’ tweets also increased harm perceptions for five diseases (all p < 0.001), with the greatest effect observed for lung cancer (β = 0.313, p < 0.001). This effect was greater among UK participants for all diseases. Interpretation Brief exposure to misinformation on Twitter reduced accurate knowledge of the presence of tar and the level of toxins compared with smoking and increased harm perceptions of e-cigarette use.

Abstract
PURPOSE Determine whether dual tobacco users have different levels of knowledge about nicotine addiction, perceived harm beliefs of low nicotine cigarettes (LNCs) and beliefs about electronic cigarettes (e-cigarettes). DESIGN Quantitative, Cross-sectional. SETTING Health Information National Trends Survey 5 (Cycle 3, 2019). PARTICIPANTS Nationally representative adult non-smokers (n=3113), exclusive cigarette smokers (n=302), and dual (cigarette and e-cigarette) users (n=77). MEASURES The survey included single item measures on whether nicotine causes addiction and whether nicotine causes cancer. A five-point Likert scale assessed comparative harm of e-cigarettes and LNCs relative to conventional combustible cigarettes (1=much more harmful, 3=equally harmful…5 = much less harmful, or don't know). ANALYSIS We used weighted multiple linear regression model to estimate means and 95% confidence intervals (CI) of e-cigarettes and LNCs beliefs by current tobacco user status. RESULTS Over 97% of dual users, 83% of non-smokers and 86% of exclusive cigarette smokers correctly identified that nicotine is addictive. The majority of subjects incorrectly identified nicotine as a cause of cancer, with dual users having the lowest proportion of incorrect responses (60%). Dual users rated e-cigarette harmfulness as less harmful than combustibles (mean=2.20; 95% CI=1.73, 2.66) while exclusive cigarette smokers and non-smokers rated them as similarly harmful. LNCs were considered equally harmful and addictive as conventional cigarettes. CONCLUSION Dual users had a higher knowledge base of tobacco-related health effects. The effectiveness of policies or medical recommendations to encourage smokers to switch from cigarettes to LNCs or e-cigarettes will need to consider accurate and inaccurate misperceptions about the harm and addictiveness of nicotine. Improved public health messages about different tobacco products are needed.
