The results suggest that socioeconomic disparities exist at multiple stages in the path to smoking cessation. Potential effects on socioeconomic disparities should be considered when implementing cessation interventions.
Objective To examine differences in vaping and smoking prevalence among adolescents in Canada, England, and the United States. Design Repeat cross sectional surveys. Setting Online surveys in Canada, England, and the US. Participants National samples of 16 to 19 year olds in 2017 and 2018, recruited from commercial panels in Canada (n=7891), England (n=7897), and the US (n=8140). Main outcome measures Prevalence of vaping and smoking was assessed for use ever, in the past 30 days, in the past week, and on 15 days or more in the past month. Use of JUUL (a nicotine salt based electronic cigarette with high nicotine concentration) and usual vaping brands were also assessed. Logistic regression models examined differences in vaping and smoking between countries and over time. Results The prevalence of vaping in the past 30 days, in the past week, and on 15 days or more in the past month increased in Canada and the US between 2017 and 2018 (P<0.001 for all), including among non-smokers and experimental smokers, with no changes in England. Smoking prevalence increased in Canada (P<0.001 for all measures), with modest increases in England, and no changes in the US. The percentage of ever vapers who reported more frequent vaping increased in Canada and the US (P<0.01 for all), but not in England. The use of JUUL increased in all countries, particularly the US and Canada—for example, the proportion of current vapers in the US citing JUUL as their usual brand increased threefold between 2017 and 2018. Conclusions Between 2017 and 2018, among 16 to 19 year olds the prevalence of vaping increased in Canada and the US, as did smoking in Canada, with little change in England. The rapidly evolving vaping market and emergence of nicotine salt based products warrant close monitoring.
Purpose Pictorial health warnings on cigarette packages are a prominent and effective means of communicating the risks of smoking; however, there is little research on effective types of message content and socio-demographic effects. This study tested message themes and content of pictorial warnings in Mexico. Methods Face-to-face surveys were conducted with 544 adult smokers and 528 youth in Mexico City. Participants were randomized to view 5–7 warnings for two of 15 different health effects. Warnings for each health effect included a text-only warning and pictorial warnings with various themes: “graphic” health effects, “lived experience”, symbolic images, and testimonials. Results Pictorial health warnings were rated as more effective than text-only warnings. Pictorial warnings featuring “graphic” depictions of disease were significantly more effective than symbolic images or experiences of human suffering. Adding testimonial information to warnings increased perceived effectiveness. Adults who were female, older, had lower education, and intended to quit smoking rated warnings as more effective, although the magnitude of these differences was modest. Few interactions were observed between socio-demographics and message theme. Conclusions Graphic depictions of disease were perceived by youth and adults as the most effective warning theme. Perceptions of warnings were generally similar across socio-demographic groups.
Objective: To examine the association of financial stress with interest in quitting smoking, making a quit attempt, and quit success. Design and participants: The analysis used data from 4,984 smokers who participated in Waves 4 and 5 (2005-2007) of the International Tobacco Control (ITC) Four Country Survey, a prospective study of a cohort of smokers in the US, Canada, UK, and Australia. Measurement: The outcomes were interest in quitting at Wave 4, making a quit attempt, and quit success at Wave 5. The main predictor was financial stress at Wave 4: “ … because of a shortage of money, were you unable to pay any important bills on time, such as electricity, telephone or rent bills?” Additional sociodemographic and smoking-related covariates were also examined. Findings: Smokers with financial stress were more likely than others to have an interest in quitting at baseline (OR: 1.63; 95% CI: 1.22-2.19), but were less likely to have made a quit attempt at follow-up (OR: 0.74; 95% CI: 0.57-0.96). Among those who made a quit attempt, financial stress was associated with a lower probability of abstinence at follow-up (OR: 0.53; 95% CI: 0.33-0.87). Conclusions: Cessation treatment efforts should consider routinely assessing the financial stress of their clients and providing additional counseling and resources for smokers who experience financial stress. Social policies that provide a safety net for people who might otherwise face severe financial problems, such as not being able to pay for rent or food, may have a favorable impact on cessation rates.
Seven of the nine health warnings selected by the FDA for implementation were among the proposed warnings rated as most effective in the current study. However, the warning(s) added for comparison were rated higher than the FDA-selected warning for five of the nine sets, suggesting some warnings could be improved for greater impact. The findings support the inclusion of a telephone "quitline" number and reinforce the importance of depicting "real" people and health effects.
Introduction JUUL has emerged as the leading brand in a rapidly evolving electronic cigarette (e-cigarette) market. JUUL is distinctive for its novel nicotine delivery method that results in high nicotine concentrations, as well as its sleek, discreet design. This study examined national estimates of JUUL among youth in the United States, including whether JUUL users report different patterns of use compared to users of other e-cigarettes. Methods Data were analyzed from the US arm of the International Tobacco Control Policy Evaluation Project (ITC) Youth Tobacco and E-cigarette Survey, an online survey conducted in July–August 2017 with youth aged 16–19 years recruited from consumer panels (n = 4086). Results Overall, 14.2% of respondents had used an e-cigarette in the past 30 days. JUUL was the second-most popular brand reported by past-30-day e-cigarette users (9.7%). Compared to e-cigarette users of other brands, JUUL users were significantly older (adjusted odds ratio [aOR] = 2.50, 95% confidence interval [CI] = 1.56 to 4.01) and reported a greater number of computers in the household (a socioeconomic status proxy; aOR = 1.55, 95% CI = 1.22 to 1.96), with no differences by sex, race/ethnicity, or student status. Controlling for sociodemographic variables, JUUL users were more likely than other e-cigarette users to have ever tried to quit e-cigarettes (aOR = 2.65, 95% CI = 1.12 to 6.30), with no differences observed by smoking status, frequency of e-cigarette use, urges to use e-cigarettes, or perceived addiction to e-cigarettes. Conclusions JUUL was among the most popular e-cigarette brands among youth, and there were few differences in sociodemographic profile or patterns of use between users of JUUL and other e-cigarette brands. Implications This study examined national estimates of JUUL e-cigarette use among youth in the United States, during the early phase of JUUL’s popularity. JUUL was among the most popular e-cigarette brands among youth, and there were few differences in sociodemographic profile or patterns of use between JUUL and other e-cigarette brands. The findings help to characterize the rapid rise of this new product category within the rapidly evolving e-cigarette market at a time when the US Food and Drug Administration and public health community are seeking to understand JUUL and its appeal among young people.
OBJECTIVES: Caffeinated energy drinks have become increasingly popular among young people, raising concern about possible adverse effects, including increased alcohol consumption and related risk behaviours. The current study examined consumption of caffeinated energy drinks and use of energy drinks with alcohol, as well as associations with socio-demographic and behavioural characteristics, among a sample of secondary school students in Ontario.METHODS: Survey data from 23,610 grade 9-12 students at 43 purposefully sampled Ontario secondary schools participating in the baseline wave (2012/13) of the COMPASS study were analyzed using generalized linear mixed-effects models. Outcomes were any energy drink use, frequency of use, and use of alcohol mixed with energy drinks; covariates were age, sex, race, spending money, body mass index (BMI), weight-related efforts and alcohol use. Two-way interactions between sex and other covariates were tested. RESULTS:Nearly one in five students (18.2%) reported consuming energy drinks in a usual week. Use of energy drinks was associated (p < 0.01) with all socio-demographic variables examined and was more common among students who were male, off-reserve Aboriginal, had some spending money, had a BMI outside of "healthy" range, were trying to lose weight, and/or reported a higher intensity of alcohol use. Interactions with sex were observed for age, spending money and weight-related efforts. Use of energy drinks mixed with alcohol in the previous 12 months was reported by 17.3% of the sample, and was associated with race, spending money, and more frequent binge drinking.CONCLUSION: Regular use of energy drinks was common among this sample of students and strongly linked to alcohol consumption.KEY WORDS: Adolescent; energy drinks; caffeine; health behaviour La traduction du résumé se trouve à la fin de l'article.
