Dynamite News Smoking during pregnancy increases risk of sudden infant death
According to a new study, mothers who smoke before and during pregnancy contribute to the risk of an infant dying suddenly and unexpectedly before their first birthday.
Washington D.C: Mothers, take note! According to a new study, mothers who smoke before and during pregnancy contribute to the risk of an infant dying suddenly and unexpectedly before their first birthday.
According to the , any amount of smoking during pregnancy - even just one cigarette a day - doubles the risk of an infant dying from sudden unexpected infant death (SUID). For women who smoked an average of 1-20 cigarettes a day, the odds of SUID increased by 0.07 with each additional cigarette smoked.
"With this information, doctors can better counsel pregnant women about their smoking habits, knowing that the number of cigarettes smoked daily during pregnancy significantly impacts the risk for SUID," said author Dr. Tatiana Anderson.
"Similar to public health campaigns that educated parents about the importance of infant sleep position, leading to a 50% decrease in sudden infant death syndrome (SIDS) rates, we hope advising women about this will result in less babies dying from these tragic causes,” added Anderson.
If no women smoked during pregnancy, Anderson and her co-authors estimate that 800 of the approximately 3,700 deaths from SUID every year in the U.S. and other parts of the world could be prevented, lowering current SUID rates by 22 per cent.

To better understand how smoking contributed to SUID risk, the researchers used computational modelling techniques to analyse maternal cigarette smoking habits for all U.S. live births from 2007 to 2011.
Of the about 20 million live births included in their analysis, over 19,000 deaths were attributed to SUID with the specific cause of death occurring from SIDS, an ill-defined and unknown cause, or accidental suffocation and strangulation in bed.
Beyond overall cigarette consumption, the researchers also looked at how smoking before pregnancy, and cutting back or quitting smoking during pregnancy, affected SUID risk.

Compared to the over half of pregnant smokers who did not reduce their smoking during pregnancy, women who reduced cigarette consumption by the third trimester saw a 12 per cent decrease in SUID risk. Successfully quitting smoking was associated with a 23 per cent reduction in risk.

Their analysis also showed that mothers who smoked three months before pregnancy and quit in the first trimester still incurred a higher risk of SUID compared to non-smokers.
Anderson said that the data from this study supports public health efforts aimed at encouraging women to quit smoking well before pregnancy.
"The most important takeaway is for women to understand that quitting smoking before and during pregnancy by far results in the greatest reduction in SUID risk. For pregnant women unable to quit entirely, every cigarette they can eliminate will reduce the odds of their child dying suddenly and unexpectedly from SUID," she said. (ANI)
