According to a report from the Daily Mail UK on January 18th, pregnant mothers who are looking to quit smoking can consider using e-cigarettes to alleviate nicotine cravings without worrying about any harm to their unborn babies.
Controversy over the use of e-cigarettes during pregnancy has persisted, with some studies warning of an increased risk of miscarriage. However, the latest findings from British researchers suggest that pregnant women using e-cigarettes are safe for both themselves and their unborn babies.
Experts from Queen Mary University in London have collected data from 23 hospitals and a support service for pregnant women. Expectant mothers were advised that they have the option to use e-cigarettes or nicotine patches instead of traditional tobacco products.
Among the participants, 47% opted for e-cigarettes, while 21% chose nicotine patches. The study subsequently compared the pregnancy outcomes of these women to ascertain whether the use of e-cigarettes or nicotine patches increased the risk of adverse pregnancy events or outcomes such as miscarriage.
By collecting saliva samples from pregnant women at the beginning and end of the study, the research team monitored the participants' nicotine levels. They also recorded any respiratory symptoms as well as the birth weight of the infants and other relevant health data.
One of the authors of the study, Professor Peter Hajek, Chief Researcher at the Wolfson Institute of Population Health at Queen Mary University of London, has stated that the research findings suggest that e-cigarettes can help pregnant women quit smoking without increasing any measurable risks. He points out that at least in late pregnancy, the harm of smoking during pregnancy appears to be more related to other chemicals in tobacco smoke rather than nicotine.
However, the authors of the report emphasize that while the research findings may alleviate some concerns about the use of nicotine substitutes during pregnancy, further research is still needed to verify these results. Although e-cigarettes are considered a safer alternative for pregnant smokers, non-smokers are not recommended to start using e-cigarettes during pregnancy, as research on the safety of e-cigarettes remains relatively limited.
The author of the report also points out that due to the relatively small scale of the study, some rare complications during pregnancy may have been overlooked. This study has been published in the journal "Addiction".
