Mom's stress during pregnancy can affect baby's iron status

Study shows maternal stress during first trimester of pregnancy puts newborns at risk for iron deficiency

2012-04-30

(Press-News.org) BOSTON – Newborns whose mothers are under stress during the first trimester of pregnancy may be at risk for low iron status, which could lead to physical and mental delays down the road, according to a study to be presented Sunday, April 29, at the Pediatric Academic Societies (PAS) annual meeting in Boston.

Iron plays an important role in the development of organ systems, especially the brain. Well-known risk factors for poor iron status in infants are maternal iron deficiency, maternal diabetes, smoking during pregnancy, preterm birth, low birthweight and multiple pregnancy.

This study, conducted by researchers from Ashkelon Academic College and Barzilai Medical Center in Israel and the University of Michigan, is the first in humans to suggest that maternal stress early in pregnancy is another risk factor for low iron status in newborns.

Researchers, led by Rinat Armony-Sivan, PhD, director of the psychology research laboratory at Ashkelon Academic College, recruited pregnant women who were about to give birth at Barzilai Medical Center. The first group of women (stress group) lived in an area where there were more than 600 rocket attacks ("Oferet Yetzuka" operation) during their first trimester of pregnancy. The control group lived in the same area and became pregnant three to four months after the rocket attacks ended.

Women were questioned briefly at the delivery room reception desk to determine whether they were healthy and without pregnancy complications. Eligible women who agreed to participate in the study were interviewed one or two days after delivery about their background and health during pregnancy. They also filled out questionnaires about depression and anxiety, and rated their stress level during pregnancy.

Cord blood was collected from newborns, and serum ferritin (iron) concentrations were measured.

Results showed that the 63 babies whose mothers were in the stress group had significantly lower cord-blood ferritin concentrations than the 77 infants in the control group.

"Our findings indicate that infants whose mothers were stressed during pregnancy are a previously unrecognized risk group for iron deficiency," Dr. Armony-Sivan said. "Pregnant women should be aware that their health, nutrition, stress level and state of mind will affect their baby's health and well-being."

Dr. Armony-Sivan concluded that it may be advisable to consider additional blood work before the well-child visit at 12 months of age, especially in high-risk populations, so that iron deficiency, with or without anemia, can be detected early and treated before it becomes chronic and severe.

Driven to distraction

2012-04-30

BOSTON – It's well-known that using a cell phone while driving can lead to motor vehicle crashes. New research — to be presented Sunday, April 29, at the Pediatric Academic Societies (PAS) annual meeting in Boston — shows that even anticipating calls or messages may distract drivers, increasing the risk of a crash. Jennifer M. Whitehill, PhD, postdoctoral fellow at Harborview Injury Prevention and Research Center at the University of Washington, and her colleagues sought to determine whether compulsive cell phone use is associated with motor vehicle crashes. They enlisted ...

Teen-led study highlights dangers of texting and driving

2012-04-30

BOSTON – Some people have questioned whether a ban on texting while driving will actually lead to more crashes because drivers will conceal their cell phones, making it more dangerous to read and type messages. Research led by high school students, however, shows that texting while driving is unsafe regardless of where the phone is positioned. The study, part of a project called Generation tXt, will be presented by one of the high school authors on Sunday, April 29, at the Pediatric Academic Societies (PAS) annual meeting in Boston. Generation tXt was designed by ...

Unruly kids may have a mental disorder

2012-04-30

BOSTON – When children behave badly, it's easy to blame their parents. Sometimes, however, such behavior may be due to a mental disorder. Mental illnesses are the No. 1 cause of medical disability in youths ages 15 and older in the United States and Canada, according to the World Health Organization. "One reason we haven't made greater progress helping people recover from mental disorders is that we get on the scene too late," said Thomas R. Insel, MD, director of the National Institute of Mental Health (NIMH) and the featured speaker at the American Academy of Pediatrics' ...

Familiarity with television fast-food ads linked to obesity

2012-04-30

BOSTON – There is a long-held concern that youths who eat a lot of fast food are at risk for becoming overweight. New research to be presented Sunday, April 29, at the Pediatric Academic Societies (PAS) annual meeting in Boston shows that greater familiarity with fast-food restaurant advertising on television is associated with obesity in young people. "We know that children and adolescents are highly exposed to fast-food restaurant advertising, particularly on television. This study links obesity in young people to familiarity with this advertising, suggesting that youth ...

TV alcohol advertising may play role in underage drinking

2012-04-30

BOSTON – Minors who were familiar with television alcohol advertisements were more likely to have tried alcoholic beverages and binge drink than those who could not recall seeing such ads, according to a study to be presented Sunday, April 29, at the Pediatric Academic Societies (PAS) annual meeting in Boston. "Underage drinking remains an important health risk in the U.S.," said lead author Susanne E. Tanski, MD, MPH, FAAP, assistant professor in the Department of Pediatrics at Children's Hospital at Dartmouth, Dartmouth-Hitchcock Medical Center. "In this study, we ...

Pacific islands may become refuge for corals in a warming climate, study finds

2012-04-30

Scientists have predicted that ocean temperatures will rise in the equatorial Pacific by the end of the century, wreaking havoc on coral reef ecosystems. But a new study shows that climate change could cause ocean currents to operate in a surprising way and mitigate the warming near a handful of islands right on the equator. As a result these Pacific islands may become isolated refuges for corals and fish. Here's how it would happen, according to the study by Woods Hole Oceanographic Institution scientists Kristopher Karnauskas and Anne Cohen, published April 29 in the ...

Huge study finds brain networks connected to teen drug abuse

2012-04-30

Why do some teenagers start smoking or experimenting with drugs—while others don't? In the largest imaging study of the human brain ever conducted—involving 1,896 14-year-olds—scientists have discovered a number of previously unknown networks that go a long way toward an answer. Robert Whelan and Hugh Garavan of the University of Vermont, along with a large group of international colleagues, report that differences in these networks provide strong evidence that some teenagers are at higher risk for drug and alcohol experimentation—simply because their brains work differently, ...

Single nanomaterial yields many laser colors

2012-04-30

PROVIDENCE, R.I. [Brown University] — Red, green, and blue lasers have become small and cheap enough to find their way into products ranging from BluRay DVD players to fancy pens, but each color is made with different semiconductor materials and by elaborate crystal growth processes. A new prototype technology demonstrates all three of those colors coming from one material. That could open the door to making products, such as high-performance digital displays, that employ a variety of laser colors all at once. "Today in order to create a laser display with arbitrary colors, ...

2 drugs better than 1 to treat youth with type 2 diabetes

2012-04-30

A combination of two diabetes drugs, metformin and rosiglitazone, was more effective in treating youth with recent-onset type 2 diabetes than metformin alone, a study funded by the National Institutes of Health (NIH) has found. Adding an intensive lifestyle intervention to metformin provided no more benefit than metformin therapy alone. The study also found that metformin therapy alone was not an effective treatment for many of these youth. In fact, metformin had a much higher failure rate in study participants than has been reported in studies of adults treated with ...

Bioluminescent technology for easy tracking of GMO

2012-04-30

It is important to be able to monitor genetically modified (GM) crops, not only in the field but also during the food processing chain. New research published in BioMed Central's open access journal BMC Biotechnology shows that products from genetically modified crops can be identified at low concentration, using bioluminescent real time reporter (BART) technology and loop mediated isothermal amplification (LAMP). The combination of these techniques was able to recognise 0.1% GM contamination of maize, far below the current EU limit of 0.9%. In agriculture GM crops have ...
