Pregnant? Here’s One More Reason To Quit Smoking

Monday, October 20th, 2014

Smoking During Pregnancy Affects Babies' Hormones and DNA Smoking during pregnancy has been linked to everything from miscarriages to low birth weight to a higher likelihood that your child will grow up with behavioral problems and respiratory infections.

Now, researchers from The Miriam Hospital in Providence, R.I. have found yet another reason for expectant mothers (and their partners) to quit. According to a study recently published in the journal Psychoneuroendocrinology, smoking during a pregnancy can lower stress response, cause DNA alterations for a gene that controls the passage of stress hormones from mother to baby, and decrease levels of stress hormones.

That’s not a good thing. Lower stress hormones don’t equal lower stress— in fact, it’s the opposite.

“Our results suggest that these newborns may not be mounting adequate hormonal response to daily stressors. Their stress systems may not be prepared for the stressors of daily life,” lead researcher Laura Stroud, Ph.D., of the Centers for Behavioral and Preventive Medicine at The Miriam Hospital, said in a news release. “This may be particularly detrimental in babies born to mothers who lack resources and parenting skills and whose babies may encounter more daily stressors.”

The small study evaluated 100 newborn-mother pairs and tracked moms through their pregnancy and up through the first month of their child’s life. The researchers tested infant cortisol (a stress-related hormone) levels and found that changes in the gene that passed cortisol from mother to child were negatively affected due to smoking.

The Centers for Disease Control and Prevention reports that 1 in every 10 mothers in the U.S. smokes during the last three months of her pregnancy. If you need help kicking the habit, follow our tips to quit here.

CDC: Teen Smoking, Sex Down, Texting Biggest New Danger

Friday, June 13th, 2014

Fewer American teenagers are having sex or smoking cigarettes, according to new figures from the Centers for Disease Control and Prevention, but public messaging efforts on the dangers of texting while driving and healthy eating remain largely ineffective in curbing dangerous behaviors.  More from NBC News:

The latest federal look at teenage behavior is reassuring and suggests that some safety messages are getting through to American youth.

On the downside, kids are fatter than ever before and just a third are eating anywhere near as many fruits and vegetables as they need to stay healthy. And less than a third are getting enough sleep.

And a very troubling new statistic shows that more than 40 percent of teenagers who drive cars admit to having texted or emailed while driving recently.

But on the whole, it’s a snapshot of progress. The Centers for Disease Control and Prevention, which organizes the every-other-year survey, was especially pleased about the drop in smoking.

“I think it’s really encouraging that we’re seeing the lowest cigarette smoking rate ever,” CDC director Dr. Tom Frieden told NBC News.

“We’ve actually reached the goal that the nation set for ourselves for 2020 early. So that’s one of the most positive trends that we see here — down to 15.7 percent — less than one out of six kids in our high schools is smoking. That’s great news.”

Smoking While Pregnant Can Diminish Impulse Control

Monday, May 19th, 2014

Women who smoke during pregnancy may be putting their babies at greater risk of ADHD and other disorders in which impulse control is compromised.  A new study may have identified the specific brain changes that are behind this risk.  More from Reuters:

People whose mothers smoked during pregnancy had weaker responses in the regions of their brains known to be involved in inhibition control, compared to those whose mothers didn’t smoke, researchers found.

Inhibition control relates to how people keep their impulses in check and resist distractions in certain situations.

“What’s quite surprising is to find such a reliable effect of prenatal smoke exposure that occurred 25 years before,” Nathalie Holz said.

Holz is the study’s lead author from Mannheim/Heidelberg University in Germany.

She and her colleagues write in JAMA Psychiatry that about 22 percent of European women smoke and about half of them continue to smoke during pregnancy.

Smoking while pregnant has been tied to attention-deficit/hyperactivity disorder, or ADHD, among kids. Children with the condition usually have trouble concentrating and controlling their impulses.

“Now we were interested in what the specific mechanisms are behind this association,” Holz said.

Ban on E-Cigarettes for Minors Considered

Friday, April 25th, 2014

A proposal by the US Food and Drug Administration to prohibit the sale of electronic cigarettes to minors is under consideration, news sources are reporting.  The new rules would ban sales, but would not prohibit online sales or advertising aimed at minors.  More from Reuters:

The long-awaited proposal, which would subject the $2 billion industry to federal regulation for the first time, is not as restrictive as some companies had feared and will likely take years to become fully effective.

Bonnie Herzog, an analyst at Wells Fargo, said the proposal is “positive for industry.”

But public health advocates lamented the fact that the proposal does not take aim at e-cigarette advertising or sweetly-flavored products, which they say risk introducing a new generation of young people to conventional cigarettes when little is known about the long-term health impact of the electronic devices.

“It’s very disappointing because they don’t do anything to rein in the wild-west marketing that is targeting kids,” said Stanton Glantz, a professor at the Center of Tobacco Control Research and Education at the University of California, San Francisco.

FDA Commissioner Margaret Hamburg said at a briefing on Wednesday that the proposal represented the first “foundational” step toward broader restrictions if scientific evidence shows they are needed to protect public health.

The number of teenagers who have tried electronic cigarettes has doubled in the past year, and if the ban is approved, the U.S. would join Britain in prohibiting minors from buying the devices.

Flavored Cigars Drawing Young People into Smoking

Monday, April 21st, 2014

New styles of flavored cigars are appealing to young people in ways cigars previously hadn’t, drawing many into a smoking habit even as cigarette use is declining among American youth.  More from Reuters:

“The cigar market is the most heavily flavored of all tobacco products,” said Cristine D. Delnevo, who led the research. “For decades, tobacco industry internal documents have highlighted that flavors appeal to youth and young people.”

Delnevo, who directs the Center for Tobacco Surveillance & Evaluation Research at Rutgers Cancer Institute of New Jersey in New Brunswick, and colleagues from the National Institutes of Health investigated recent market and survey data on flavored cigar use among young people.

Delnevo and her coauthors analyzed an annual survey of drug and alcohol use among Americans ages 12 and up. For this study, the researchers selected the 6,700 survey responders in 2010 and 2011 who reported smoking cigars in the previous month and had noted their usual brand.

They found that 8 percent of men and 2 percent of women said they had smoked a cigar in the past 30 days, but 11 percent of people between ages 18 and 25 years old had smoked a cigar – more than any other age group.

Three quarters of cigar smokers reported a usual brand that offers flavored varieties, according to the results published in the journal Tobacco Control.
