This month, UKECRF published analysis of three studies. The first focused on the cardiovascular effects of e-cigarettes by researchers at the University of Dundee, the second is a small observational study conducted by researchers at London South Bank University, and the last is a systematic review addressing the influence of social factors on e-cigarette intentions and use.
For “Cardiovascular Effects of Switching From Tobacco Cigarettes to Electronic Cigarettes”, researchers recruited 114 smokers to see if there were measurable health benefits in blood flow from the heart to other tissues and organs as a result of switching to vaping.
“At one month follow up, the researchers found a significant improvement … among participants who vaped (the nicotine and nicotine free groups combined) compared to those who continued to smoke.”
For “Effects of e-cigarettes versus nicotine replacement therapy on short-term smoking abstinence when delivered at a community pharmacy”, researchers tested the effectiveness of offering an e-cigarette with and without nicotine replacement therapy on 4-6-week quit rates in adult smokers seeking support from a community pharmacy.
They looked at 115 smokers, of which 37 choose to switch to vaping; “Smokers who chose an e-cigarette either alone or with NRT were more likely to have stopped smoking at four weeks”.
UKECRF said: “Although this study was small, the fact that participants selected which product rather than being randomised, and that validated (CO) quit rates were not available or reported for all participants, it still contains useful information that could inform future studies.”
The final study, “Social Influence in the Uptake and Use of Electronic Cigarettes: A Systematic Review” warned: “Given the increased popularity among non-smokers and the potential for advertising to increase e-cigarette use, closer public health monitoring of e-cigarette uptake by non-smokers is warranted. Future primary research should be designed to measure how social factors affect smokers and non-smokers differently.”
The experts reviewing the paper said: “This review is vulnerable to any limitations of the individual studies included. There was no indication of how well studies adjusted for confounding factors. Therefore, this review cannot establish causal relationships.
Although the risk of bias was assessed in randomised control trials, 81% of the studies were not RCTs. A quality validation tool was not used to assess the quality of all studies meaning the quality was not weighted in the analysis. Due to heterogeneity in the data, a meta-analysis was not performed. Therefore, common effects of the studies cannot be statistically verified.”
The UKECRF suggested that people interested in vape research might wish to look at the following studies from the end of 2019:
