Beard E, et al. - Researchers sought to determine up-to-date estimates of the effects of changes in the prevalence of electronic cigarette (e-cigarette) use in England on changes in smoking cessation activities and daily cigarette consumption among smokers in England. They conducted a time series analysis of population trends among participants from the Smoking Toolkit Study, which includes repeated, cross-sectional household surveys of individuals aged 16 years and older in England. The analysis revealed a positive correlation of changes in the prevalence of e-cigarette use in England with the overall quit rates and quit success rates but this was not clearly correlated with the prevalence of quit attempts and mean cigarette consumption. They observed an increase in overall quit rates by 0.054% and 0.050%, respectively, for every 1% increase in the prevalence of e-cigarette use by smokers and e-cigarette use during a quit attempt. Further, an increase in quit success rates by 0.060% was observed for every 1% increase in the prevalence of e-cigarette use during a quit attempt.
