Brief Summary:
Smoking is the "leading, preventable death-cause worldwide", being responsible for almost 700,000 deaths in the E.U. annually. Therefore, implementing successful, long-term smoking cessation strategies is a long-term priority for the NHS.
Recent evidence suggests that e-cigarettes (i.e., vaping) are a successful cessation tool, with around 3.6 million users in the UK. There are concerns about long-term vaping, particularly in relation to their cardiovascular effects, as there are no relevant, longitudinal studies.
Therefore, we propose a 38-month, four-group longitudinal study exploring the cardiovascular physiological effects of the use of e-cigarettes over a two-year period, informing policy makers and e-cigarette users (vapers). Our study was developed with the support of vapers.
The main research question is whether there are any differences in cardiovascular physiology between vapers, who are ex-smokers (Group A), vapers with no previous smoking experience (Group B), dual users (i.e., those who vape and smoke (Group C) and ex-smokers who don't vape (Group D).
Two-hundred participants from Sheffield and Leeds will be invited on five occasions (baseline, as well as 6-,12-,18- and 24-months post-baseline).
We will assess macrovascular and lung function, cardiovascular disease risk (through questionnaires and blood biomarkers), vaping and smoking dependence, smoking and and vaping history among others.
