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.

Prenatal Smoking, Drinking Increases SIDS Risk; Says New Study

According to the researchers, these risks were in comparison to infants who were either not exposed to tobacco or alcohol during gestation or whose mothers quit tobacco or alcohol use by the end of the first trimester

Children born to mothers who drank and smoked beyond the first three months of pregnancy have 12-fold increased risk for sudden infant death syndrome (SIDS), says a new study.

SIDS is the sudden, unexplained, death of an infant under one year of age. Many studies have shown that the risk of SIDS is increased by maternal smoking during pregnancy.

Some studies have also found that prenatal alcohol exposure, particularly from heavy drinking during pregnancy, can increase SIDS risk.

The findings, published in the journal The Lancet, provide a look at how SIDS risk is influenced by the timing and amount of prenatal exposure to tobacco and alcohol.

“Our findings suggest that combined exposures to alcohol and tobacco have a synergistic effect on SIDS risk, given that dual exposure was associated with substantially higher risk than either exposure alone,” said said first author Amy J Elliot from Avera Health Centre for Pediatric and Community in US.

For the findings, researchers followed the outcomes of nearly 12,000 pregnancies among women from two residential areas in Cape Town, South Africa; and five sites in the US.

The study sites were selected for their high rates of prenatal alcohol use and SIDS, and to include populations where the ethnic and socioeconomic disparities in SIDS remains understudied.

The researchers determined one-year outcomes for about 94 per cent of the pregnancies.

They found that 66 infants died during that time, including 28 SIDS deaths and 38 deaths from known causes.

In addition to the almost 12-fold increased SIDS risk from combined smoking and drinking beyond the first trimester of pregnancy, they determined that the risk of SIDS was increased five-fold in infants whose mothers reported they continued smoking beyond the first trimester, and four-fold in infants whose mothers reported they continued drinking beyond the first trimester.

According to the researchers, these risks were in comparison to infants who were either not exposed to tobacco or alcohol during gestation or whose mothers quit tobacco or alcohol use by the end of the first trimester. (IANS)
