Exposure to pregnant cigarette smoke increases a protein in the newborn’s body, which may be exposed only decades later.
Scientists at the University of Kentucky (USA) discovered that tobacco chemicals passing through the placenta will promote chemerin molecules in the infant’s body. This increase is parallel to the reduction of DNA methylation, in other words, tobacco has directly affected the regulation of DNA, leading to an imbalance in chemerin production.
According to Dr. Leryn Reynolds, lead author of the study, chemerin is a “promotes obesity” protein produced in fat cells and its consequences may be decades later: the older the child is. the more easily you are overweight and the more you find it difficult to lose weight, compared to people of the same age, the same lifestyle and vegetative regime.
This is a very interesting issue because science is increasingly proving the unpredictable consequences of the obesity pandemic, the most shocking of which is a previous study by the Cancer Research UK that is obese. usurpation both smokes and becomes the leading carcinogen, involving 12 deadly cancers.
Previous studies have also shown that pregnant women exposed to smoke increase the risk of premature birth and stillbirth. Therefore, according to the authors, new findings provide an additional reason for pregnant women not to touch cigarettes. Surveys in the United States show that although the proportion of women who smoke has decreased significantly, there are still people who take drugs even while pregnant.
The study did not mention passive smoking, but many previous studies show that passive smoking is also a form of cigarette smoke exposure, and may even be more harmful than active, so scientists Learn to advise pregnant women to best stay away from smoke-free environments.
Also according to the UK Cancer Research Agency, “second-hand” smoke, the smoke that passive smokers inhale, includes smoke from burning cigarettes and smoke released by smokers four times more harmful. compared to smoke that smokers directly put into the body. Statistics show that second-hand smoke has a much higher concentration of carcinogens, for example, carbon monoxide triples, nitrosamine 10-30 times and ammonia 15-300 times.
According to a research team from the University of Kentucky, another factor threatening exposure to tobacco from pregnant women is e-cigarettes. Many people still think it is safe, including many young women, but scientific studies have proved it to be equally toxic, even some even more than traditional cigarettes. The study has just been published in the scientific journal Experimental Physiology.
