Electronic cigarette use in young people in Great Britain 2013–2014

OBJECTIVES The recent growth in the market for electronic cigarettes (e-cigarettes) has led to concerns over their use by young people. It is therefore important to examine trends in the perception and use of e-cigarettes and conventional cigarettes in this group. STUDY DESIGN Two-wave cross-sectional survey design. METHODS Young people aged 11-18 in Great Britain were surveyed online by YouGov in 2013 and 2014. Use of e-cigarettes, together with perceived health harms and intention to use were assessed and compared in relation to cigarette smoking history, age and gender. RESULTS Ever-use of e-cigarettes increased significantly from 4.6% (95% CI 3.8-5.7) in 2013 to 8.2% (95% CI 7.0-9.6) in 2014. Monthly or more use of e-cigarettes increased from 0.9% (95% CI 0.5-1.5) to 1.7 (1.2-2.4), but remained rare in never-smokers at under 0.2%. The proportion of young people who perceived e-cigarettes to be less harmful to users than cigarettes fell from 73.4% (95% CI 71.0-75.8) to 66.9% (95% CI 64.5-69.2), while the proportion who considered e-cigarettes to cause similar levels of harm increased from 11.8% (95% CI 10.0-13.5) to 18.2% (95% CI 16.3-20.1). Of the 8.2% of e-cigarette ever-users in 2014, 69.8% (95% CI 62.2%-77.3%) had smoked a cigarette prior to using an e-cigarette, while 8.2% (95% CI 4.1%-12.2%) first smoked a cigarette after e-cigarette use. CONCLUSIONS A growing proportion of young people in Great Britain believe e-cigarettes are as harmful as smoking tobacco. Use of e-cigarettes by young people is increasing, but is largely confined to those who smoke.

Tobacco point-of-sale displays in England: a snapshot survey of current practices

Background Tobacco displays at the point of sale (PoS) are an important means for the tobacco industry to communicate with consumers. With regulations prohibiting PoS displays recently having come into force in Ireland, passed into law in England, Wales and Northern Ireland and some Australian states, and being considered in New Zealand, Finland and Brazil, this is an increasingly important issue. This study explores the nature of displays, the extent to which they are tobacco industry funded, and the relation between the tobacco companies and retailers. Methods Three areas were chosen to gain a snapshot of PoS displays in England. Over 100 retailers were visited, with interviews taking place on site. Information was gathered on the type and size of tobacco display, who was paying for the display, requirements and incentives, and visits by industry representatives. Results The majority of retailers had gantries provided by tobacco companies. A minority of these were fitted with automated dispensers called retail vending machines. Attractive lighting and colour were often used to highlight particular products. Most retailers were being visited by industry representatives who checked displays. Some retailers also reported incentives offered to them for displaying products. Conclusions The results suggest that the tobacco industry presence and control in the retail environment is significant. Tobacco companies overwhelmingly provided tobacco gantries in the shops surveyed and influenced displays through a combination of requirements and incentives. The extensive involvement of tobacco companies in providing and monitoring retail displays suggests the importance of implementing policies to end this form of advertising.

Young People’s Use of E-Cigarettes across the United Kingdom: Findings from Five Surveys 2015–2017

Concern has been expressed about the use of e-cigarettes among young people. Our study reported e-cigarette and tobacco cigarette ever and regular use among 11–16 year olds across the UK. Data came from five large scale surveys with different designs and sampling strategies conducted between 2015 and 2017: The Youth Tobacco Policy Survey; the Schools Health Research Network Wales survey; two Action on Smoking and Health (ASH) Smokefree Great Britain-Youth Surveys; and the Scottish Schools Adolescent Lifestyle and Substance Use Survey. Cumulatively these surveys collected data from over 60,000 young people. For 2015/16 data for 11–16 year olds: ever smoking ranged from 11% to 20%; regular (at least weekly) smoking between 1% and 4%; ever use of e-cigarettes 7% to 18%; regular (at least weekly) use 1% to 3%; among never smokers, ever e-cigarette use ranged from 4% to 10% with regular use between 0.1% and 0.5%; among regular smokers, ever e-cigarette use ranged from 67% to 92% and regular use 7% to 38%. ASH surveys showed a rise in the prevalence of ever use of e-cigarettes from 7% (2016) to 11% (2017) but prevalence of regular use did not change remaining at 1%. In summary, surveys across the UK show a consistent pattern: most e-cigarette experimentation does not turn into regular use, and levels of regular use in young people who have never smoked remain very low.

The Association Between Smoking and Electronic Cigarette Use in a Cohort of Young People

Purpose Electronic cigarette (e-cigarette) use is associated with smoking initiation among young people; however, it is also possible that smoking is associated with e-cigarette initiation. This study explores these associations among young people in Great Britain. Methods A longitudinal survey of 1,152 11- to 18-year-olds was conducted with baseline in April 2016 and follow-up between August and October 2016. Logistic regression models and causal mediation analyses assessed whether (1) ever e-cigarette use and escalation were associated with smoking initiation (ever smoking at follow-up) among baseline never smokers (n = 923), and (2) ever smoking and escalation were associated with e-cigarette initiation (ever e-cigarette use at follow-up) among baseline never e-cigarette users (n = 1,020). Results At baseline, 19.8% were ever smokers and 11.4% were ever e-cigarette users. Respondents who were ever e-cigarette users (vs. never users, 53% vs. 8%, odds ratio [OR] = 11.89, 95% confidence interval [CI] = 3.56–39.72) and escalated their e-cigarette use (vs. did not, 41% vs. 8%, OR = 7.89, 95% CI = 3.06–20.38) were more likely to initiate smoking. Respondents who were ever smokers (vs. never smokers, 32% vs. 4%, OR = 3.54, 95% CI = 1.68–7.45) and escalated their smoking (vs. did not, 34% vs. 6%, OR = 5.79, 95% CI = 2.55–13.15) were more likely to initiate e-cigarette use. There was a direct effect of ever e-cigarette use on smoking initiation (OR = 1.34, 95% CI = 1.05–1.72), and ever smoking on e-cigarette initiation (OR = 1.08, 95% CI = 1.01–1.17); e-cigarette and smoking escalation, respectively, did not mediate these effects. Conclusions Among young people in Great Britain, ever e-cigarette use is associated with smoking initiation, and ever smoking is associated with e-cigarette initiation.

Restrictions on the use of e-cigarettes in public and private places—current practice and support among adults in Great Britain

Abstract Background Debates around policies regulating e-cigarette use make it important to obtain an overview of current practice, people’s attitudes and correlates of policy support. Aims were to assess (i) current practices for e-cigarette use in homes and workplaces; (ii) characteristics associated with allowing e-cigarette use in the home; and (iii) level of, and characteristics associated with, support for extending smoke-free legislation to include e-cigarettes. Methods Online survey in 2016, n = 11 389 adults in Great Britain. Descriptives for all measures; multivariable logistic regressions assessed correlates of allowing e-cigarette use and support for extension of legislation. Results Most (79%) reporting on workplace policies reported some level of restrictions on e-cigarette use. Small majorities would not allow e-cigarette use in their home (58%) and supported an extension of smoke-free legislation (52%; 21% opposed). Allowing use was less likely and supporting an extension more likely among men, respondents from a higher socio-economic status, ex-smokers, never-smokers, non-users of e-cigarettes and respondents with increased perceived harm of e-cigarettes or nicotine (all P < 0.001). Older respondents were less likely to allow use and to support an extension and Labour voters more likely to allow use. Conclusions In Great Britain, the majority of workplaces has policies restricting e-cigarette use. Over half of adults would not allow use of e-cigarettes in their home and support prohibiting the use of e-cigarettes in smoke-free places. Adjusting for socio-demographics, more restrictive attitudes are more common among never-smokers, never-users and those with increased perception of relative harms of e-cigarettes or nicotine as cause of smoking-related illness.

Waterpipe tobacco smoking prevalence among young people in Great Britain, 2013-2016

Background One percent of adults in Great Britain use waterpipe tobacco at least monthly, however national epidemiological evidence among young people is absent. This study aims to assess waterpipe tobacco prevalence and correlates among young people in Great Britain. Methods Data were analyzed from online surveys conducted annually from 2013 to 2016 with weighted national samples of 11 to 18-year olds in Great Britain (annual n = 1936-2059). Primary outcome measures were at least monthly waterpipe tobacco use and lifetime waterpipe tobacco use. Binary logistic regression models tested the association between these outcomes and age, sex, country of residence and other tobacco consumption. Results Between 2013 and 2016, 1.7% (95% CI 1.5-2.1%) used waterpipe tobacco at least monthly and 9.9% (95% CI 9.2-10.7%) used waterpipe in their lifetime. There were no changes in prevalence over time. At least monthly use was associated with older age groups [16-18 years vs. 11-15 years, adjusted odds ratio (AOR) 2.63, 95% CI 1.55-4.46], male sex (AOR 1.82, 95% CI 1.23-2.71) and other tobacco consumption (e.g. lifetime cigarette use AOR 10.30, 95% CI 5.22-20.29). Lifetime use had similar correlates, but was not associated with male sex (AOR 0.97, 95% CI 0.80-1.17). Conclusions One in 10 young people in Great Britain have tried waterpipe tobacco, though more frequent use appears low. We found no evidence of increasing or decreasing prevalence of waterpipe use between 2013 and 2016. Being male, older and a concurrent user of other tobacco products were correlated with waterpipe tobacco use.

Harm perceptions of electronic cigarettes and nicotine: A nationally representative cross-sectional survey of young people in Great Britain

Highlights • Two thirds (63%) had accurate harm perceptions of e-cigarettes.• Few (9%) had accurate harm perceptions of nicotine.• Accurate harm perceptions of e-cigarettes and nicotine were positively associated.• E-cigarette users, but not smokers, had more accurate e-cigarette harm perceptions.• Neither smoking nor e-cigarette use were associated with nicotine harm perceptions.
