Rules about smoking and vaping in the home: findings from the 2016 International Tobacco Control Four Country Smoking and Vaping Survey.

ABSTRACT:

Aims

To examine rules about smoking and vaping in the home in relation to beliefs about the relative harm of second-hand vapor (SHV) compared with second-hand smoke (SHS) in four countries: Canada, United States, England and Australia.

Design

Data were available from 12 294 adults (18+) who participated in the 2016 (wave 1) International Tobacco Control Four Country Smoking and Vaping (ITC 4CV1) Survey.

Participants

All participants were current or recent former adult smokers.

Measurements

Data were analyzed by weighted logistic regression on rules about smoking and vaping in the home; odds ratios and 95% confidence intervals were reported, adjusted for demographic and behavioral variables.

Findings

Of all respondents, 37.4% allowed smoking inside their home. Among a subset who were current vapers (n = 6135), 60.4% allowed vaping in their homes. After controlling for demographic and behavioral characteristics, beliefs about the harm of SHV compared with SHS was not associated with allowing smoking in the home, but was associated with allowing vaping in the home [odds ratio (OR) = 2.86 in Canada, OR = 1.82 in the United States and OR = 1.68 in England]. Characteristics that were associated with rules about vaping inside the home included daily vaping (OR = 2.95, 2.04-4.26; OR = 7.00, 4.12-11.87; OR = 5.50, 3.40-8.88; OR = 7.78, 1.90-31.80), living with a spouse who vapes (OR = 2.48, 1.54-3.98; OR = 2.69, 1.42-5.11; OR = 4.67, 2.74-7.95; OR = 21.82, 2.16-220.9) and living with children aged under 18 years (OR = 0.50, 0.37-0.68; OR = 0.89, 0.48-1.65; OR = 0.76, 0.53-1.09; OR = 0.26, = 0.11-0.61) in Canada, the United States, England and Australia, respectively. Similar characteristics were associated with rules about smoking inside the home.

Conclusions

Among current and former smokers in 2016 in Canada, the United States, England and Australia, 37.4% allowed smoking in the home; 60.4% of current vapers allowed vaping. Both concurrent users and exclusive vapers were more likely to allow vaping than smoking inside the home. Allowing vaping inside the home was correlated with the belief that second-hand vapor is less harmful than second-hand smoke.

Project description:IntroductionTo examine whether perceived injunctive and descriptive social norms towards cigarette and nicotine vaping product (NVP) use predicted subsequent trying NVPs and attempts to quit cigarette smoking amongst current smokers and whether associations varied across countries.Aims and methodsThree waves of longitudinal cohort data from the International Tobacco Control Four Country Smoking and Vaping Survey were collected between 2016 and 2020 from 2290 adult smokers in Canada, Australia, England, and the United States who had never used NVPs at baseline (either wave 1 or wave 2) and followed up at the subsequent wave (wave 2 or wave 3, respectively) were analyzed using Generalized Estimating Equations.ResultsOf the injunctive and descriptive norm measures for smoking and NVP use, NVP initiation was only independently predicted by the injunctive interpersonal norm for NVP use, with perceived approval of NVP use by important others predicting higher odds of trying NVPs (AOR = 1.65, 95% CI = 1.20 to 2.27). This predictive effect was independent of baseline quit intention with no country variations found. By contrast, making cigarette smoking quit attempts were independently predicted by both injunctive and descriptive interpersonal norms with perceived disapproval of smoking by important others (AOR = 1.65, 95% CI = 1.38 to 1.99) and close friends using NVPs (AOR = 1.37, 95% CI = 1.04 to 1.79), both associated with higher odds of smoking quit attempts.ConclusionsAdult smokers who perceive NVP use as normative, either because such behavior is socially approved or common within their close social networks, appear more inclined to try NVPs or make smoking quit attempts than smokers who do not.ImplicationsSocial norms can shape a person's behavior and result in behavior change. This study shows that initiation of NVP use behavior among smokers can be reliably predicted by their perception of whether NVP use is acceptable to those important to them within their close social networks. Similarly, any attempts to stop cigarette smoking can be predicted by their perception of how acceptable cigarette smoking is among those who are important to them and whether any of their close friends use NVPs. Changing social norms towards cigarette smoking and NVP use could therefore be incorporated into smoking cessation interventions to help smokers to quit and/or switch to NVP use.

Project description:Background and aimsMost population studies that evaluate the relationship between nicotine vaping and cigarette cessation focus on limited segments of the smoker population. We evaluated vaping uptake and smoking cessation considering differences in smokers' plans to quit.DesignLongitudinal International Tobacco Control (ITC) Four Country Smoking and Vaping Surveys were conducted in 2016, 2018 and 2020.SettingThis study was conducted in the United States, Canada, England and Australia.ParticipantsParticipants of this study were adult daily cigarette smokers who had not vaped in the past 6 months at baseline and had participated in two or more consecutive waves of the ITC Four Country Smoking and Vaping Surveys (n = 2815).MeasurementsPlans to quit cigarette smoking was assessed at baseline (within 6 months, beyond 6 months, not planning to quit) and at follow-up (within 6 months vs not within 6 months), cigarette smoking cessation was assessed at follow-up (smoking less than monthly [including complete cessation] vs daily/weekly/monthly smoking) and inter-wave vaping uptake was assesed between baseline and follow-up (none, only non-daily vaping and any daily vaping). Generalized estimating equations were used to evaluate whether inter-wave vaping uptake was associated with smoking cessation at follow-up and with planning to quit at follow-up, each stratified by plans to quit smoking at baseline.FindingsOverall, 12.7% of smokers quit smoking. Smokers not initially planning to quit within 6 months experienced higher odds of smoking cessation when they took up daily vaping (32.4%) versus no vaping (6.8%; adjusted odds ratio [AOR], 8.58; 95% CI, 5.06-14.54). Among smokers planning to quit, smoking cessation rates were similar between those who did and did not take up daily vaping (25.1% vs 16.8%; AOR, 1.91; 95% CI, 0.91-4.00), although we could not account for potential use of cessation aids. Daily vaping uptake was associated with planning to quit smoking at follow-up among those initially not planning to quit (AOR,6.32; 95% CI, 4.17-9.59).ConclusionsUptake of nicotine vaping appears to be strongly associated with cigarette smoking cessation among smokers with no initial plans to quit smoking. Excluding smokers not planning to quit from studies on vaping and smoking cessation may underestimate potential benefit of daily vaping for daily smokers.

Project description:Background and aimsIt has been proposed that many smokers switch to vaping because their nicotine addiction makes this their only viable route out of smoking. We compared indicators of prior and current cigarette smoking dependence and of relapse in former smokers who were daily users of nicotine vaping products ('vapers') or who were not vaping at the time of survey ('non-vapers').DesignCross-sectional survey-based comparison between vaping and non-vaping former smokers, including a weighted logistic regression of vaping status onto predictor variables, adjusting for covariates specified below.SettingUnited States, Canada, Australia and England.ParticipantsA total of 1070 people aged 18+ years from the 2016 International Tobacco Control (ITC) Four Country Smoking and Vaping Wave 1 Survey who reported having ever been daily smokers but who stopped less than 2 years ago and who were currently vapers or non-vapers.MeasurementsDependent variable was current vaping status. Predictor variables were self-reported: (1) smoking within 5 minutes of waking and usual daily cigarette consumption, both assessed retrospectively; (2) current perceived addiction to smoking, urges to smoke and confidence in staying quit. Covariates: country, sample sources, sex, age group, ethnicity, income, education, current nicotine replacement therapy use and time since quitting.FindingsVapers were more likely than non-vapers to report: (1) having smoked within 5 minutes of waking [34.3 versus 15.9%, adjusted odds ratio (aOR) = 3.74, 95% confidence interval (CI) = 1.99, 7.03), χ2 = 16.92, P < 0.001]; having smoked > 10 cigarettes/day (74.4 versus 47.2%, aOR = 4.39, 95% CI = 2.22, 8.68), χ2 = 18.18, P < 0.001); (2) perceiving themselves to be still very addicted to smoking (41.3 versus 26.2%, aOR = 2.89, 95% CI = 1.58, 5.30, χ2 = 11.87, P < 0.001) and feeling extremely confident about staying quit (62.1 versus 36.6%, aOR = 3.22, 95% CI = 1.86, 5.59, χ2 = 17.36, P < 0.001). Vapers were not more likely to report any urges to smoke than non-vapers (27.7 versus 38.8%, aOR = 0.86, 95% CI = 0.44, 1.65, χ2 = 0.21, P = 0.643).ConclusionsWhile former smokers who currently vape nicotine daily report higher levels of cigarette smoking dependence pre- and post-cessation compared with former smokers who are current non-vapers, they report greater confidence in staying quit and similar strength of urges to smoke.

Project description:IntroductionTo test whether urges to smoke and perceived addiction to smoking have independent predictive value for quit attempts and short-term quit success over and above the Heaviness of Smoking Index (HSI).Aims and methodsData were from the International Tobacco Control Four Country Smoking and Vaping Wave 1 (2016) and Wave 2 (2018) surveys. About 3661 daily smokers (daily vapers excluded) provided data in both waves. A series of multivariable logistic regression models assessed the association of each dependence measure on odds of making a quit attempt and at least 1-month smoking abstinence.ResultsOf the 3661 participants, 1594 (43.5%) reported a quit attempt. Of those who reported a quit attempt, 546 (34.9%) reported short-term quit success. Fully adjusted models showed that making quit attempts was associated with lower HSI (adjusted odds ratio [aOR] = 0.81, 95% confidence interval [CI] = 0.73 to 0.90, p < .001), stronger urges to smoke (aOR = 1.08, 95% CI = 1.04 to 1.20, p = .002), and higher perceived addiction to smoking (aOR = 0.52, 95% CI = 0.32 to 0.84, p = .008). Lower HSI (aOR = 0.57, 95% CI = 0.40 to 0.87, p < .001), weaker urges to smoke (aOR = 0.85, 95% CI = 0.76 to 0.95, p = .006), and lower perceived addiction to smoking (aOR = 0.55, 95% CI = 0.32 to 0.91, p = .021) were associated with greater odds of short-term quit success. In both cases, overall R2 was around 0.5.ConclusionsThe two additional dependence measures were complementary to HSI adding explanatory power to smoking cessation models, but variance explained remains small.ImplicationsStrength of urges to smoke and perceived addiction to smoking may significantly improve prediction of cessation attempts and short-term quit success over and above routinely assessed demographic variables and the HSI. Stratification of analyses by age group is recommended because the relationship between dependence measures and outcomes differs significantly for younger (aged 18-39) compared to older (aged older than 40) participants. Even with the addition of these extra measures of dependence, the overall variance explained in predicting smoking cessation outcomes remains very low. These measures can only be thought of as assessing some aspects of dependence. Current understanding of the factors that ultimately determine quit success remains limited.
