Just one cigarette a day during pregnancy can double the risk of sudden unexpected infant death (SUID), warned a study.

SUID is defined as sudden and unexpected death of a baby below one year of age, in which the cause is not obvious before investigation.

For women, who smoked an average of 1-20 cigarettes a day, the odds of SUID increased by 0.07 with each additional cigarette, according to the study published in Pediatrics.

“With this information, doctors can better counsel pregnant women about their smoking habits, knowing that the number of cigarettes smoked daily during pregnancy significantly increase the risk of SUID,” said lead author Tatiana Anderson, from the Seattle Children’s Research Institute.

“The most important takeaway is for women to understand that quitting smoking before and during pregnancy by far results in the greatest reduction in the SUID risk,” she said. Pixabay

“We hope advising women about this risk will result in less babies dying from these tragic causes.” Women who reduced smoking by the third trimester saw a 12 per cent decrease in SUID risk. Quitting smoking was associated with a 23 per cent reduction in the risk.

“The most important takeaway is for women to understand that quitting smoking before and during pregnancy by far results in the greatest reduction in the SUID risk,” she said.  For the study, the team used computational modelling techniques to analyse maternal cigarette smoking habits for about 20 million births in the US.

The analysis also showed mothers who smoked three months before pregnancy and quit in the first trimester still had a higher risk of SUID compared with non-smokers.

The data supports public health efforts aimed at encouraging women to quit smoking well before pregnancy, Anderson said. (IANS)

E-cigarettes responsible for a decline in Cigarette Smoking among the Youth

New York, Jan 23, 2017: E-cigarettes — seen as responsible for a decline in cigarette smoking among the youth — are actually attracting a new population of adolescents who might not otherwise have smoked tobacco products, researchers warned.

The findings showed that the e-cigarettes attract low-risk adolescents who may not have used nicotine at all if e-cigarettes did not exist.

“E-cigarettes are encouraging — not discouraging — youth to smoke and to consume nicotine and are expanding the tobacco market,” said Stanton A. Glantz, Professor at University of California – San Francisco.

Several previous studies have reported that adolescents who start with e-cigarettes are more likely to subsequently smoke traditional cigarettes.

According to researchers, they did not find any evidence that e-cigarettes have caused youth smoking to decline. In fact, combined e-cigarette and cigarette use among adolescents in 2014 was higher than total cigarette use in 2009, they stated.

“The study didn’t find any evidence that e-cigarettes are causing youth smoking to decline,” added Lauren Dutra, social scientist at RTI International — a not-for-profit research organisation based in North Carolina, US.

The “recent declines in youth smoking are likely due to tobacco control efforts, not to e-cigarettes,” Dutra noted.

For the new study, the team examined survey data from more than 140,000 middle and high school students who completed the CDC’s National Youth Tobacco Survey between 2004 and 2014.

The results showed that cigarette smoking among US adolescents declined during that decade, but did not decline faster after the advent of e-cigarettes in the US between 2007 and 2009.

The study was published online in the journal Pediatrics. (IANS)
