Cautious! If You Smoke During Pregnancy Your Child Is At Grater Risk Of Being Obese

The current and future results could provide a springboard for the development of effective treatments against pediatric and adult obesity in babies born to smokers as well as those exposed to other in utero environmental exposures, the team noted.

Children whose mothers smoked during their pregnancy are at increased risk of being obese later in life, say researchers.

The findings, published in the journal Experimental Physiology, showed that chemerin, a protein that is produced by fat cells and appears to play a role in energy storage, was more prevalent in the skin and isolated cells of infants whose mothers smoked during pregnancy.

Previous research had shown that chemerin is present in higher levels in the blood of obese people.

The new results suggest that smoking in pregnancy could lead to changes in the regulation of the genes that play an important role in fat cell development and, by extension, obesity.

“It has been consistently shown that mothers who smoke during pregnancy confer increased risk of obesity to their baby, but the mechanisms responsible for this increased risk are not well understood,” said Kevin Pearson from the University of Kentucky in the US.

“Our work demonstrated that expectant mothers who smoke cigarettes during pregnancy induce distinct changes in chemerin gene expression in their offspring,” Pearson said.

Avoid Smoking During Pregnancy To Prevent Premature Births

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

Expecting mothers, take note. As smoking during pregnancy is linked with negative health outcomes, a team of researchers has found that smoking cessation during pregnancy may reduce the risk of pre-term birth.

The findings, published in the JAMA Network Open journal, showed that the probability of pre-term birth decreased with earlier smoking cessation in pregnancy — up to a 20 per cent relative decrease if cessation occurred at the beginning of pregnancy.

“Of concern, though, given the substantial benefits of smoking cessation during pregnancy is that the proportion of pre-pregnancy smokers who quit smoking during pregnancy has remained essentially stagnant since 2011,” said lead author Samir Soneji from The Dartmouth Institute for Health Policy and Clinical Practice in the US.

For the study, the researchers conducted a cross-sectional study of more than 25 million pregnant women who gave birth to live neonates during a six-year period — measuring their smoking frequency three months prior to pregnancy and for each trimester during pregnancy.

The negative health impacts of cigarette smoking during pregnancy, including low birth weight, delayed intrauterine development, pre-term birth, infant mortality, and long-term developmental delays, are well known.

But the good news is that the proportion of women who start their pregnancy as smokers has been declining in recent years, the researchers said.

However, the study also found that only about 25 per cent of women who smoked prior to pregnancy were able to quit throughout their pregnancy, and approximately 50 per cent of women who smoked during their pregnancy did so with high frequency (more than 10 cigarettes per day).

The researcher plans to look at quit rates and smoking intensity and their impact on the risk of infant mortality.

“Thankfully most premature babies end up doing well,” he said.

“But premature birth is strongly linked to infant mortality. If we determine quitting, and quitting early, reduces the risk of infant mortality, then that may speak to mothers even more saliently about the importance of smoking cessation,” he added. (IANS)
