Smoking is definitely a harmful habit that has negative effects on smokers and non-smokers; not to mention the planet as a whole. It is always encouraged to stop smoking to lower the risk of dangerous diseases like cancer. However, it is extremely advised to not smoke while being pregnant; which should be used as a way to stop smoking all the way.
However, a recent study conducted by a team of researchers from The Dartmouth Institute for Health Policy and Clinical Practice show results that proves that quitting smoking will lower risks of having preterm births.
This study was led by PhD holder Samir Soneji who is also an associate professor at The Dartmouth Institute for Health Policy and Clinical Practice. The co-author of the study is also a PhD holder called with Hiram Beltrán-Sánchez who works as an associate professor at the University of California, Los Angeles. They published the paper and the results in the JAMA Network Open Journal.
Dr. Samir commented on his results saying, “Of concern, though, given the substantial benefits of smoking cessation during pregnancy, is the proportion of pre-pregnancy smokers who quit smoking during pregnancy has remained essentially stagnant since 2011.”
Many different side effects can be expected from smoking while pregnant including, preterm birth , low birth weight, infant mortality, delayed intrauterine development and long-term developmental delays.
This is why the study encourages for lowering the rates of pregnant women being smokers to help having a healthy child.
