Prenatal cocaine use linked to behavior problems in boys

12.08.2004


Boys exposed to persistent levels of cocaine in the womb are more likely to have behavioral problems like hyperactivity in their early school years, new research suggests.

But girls who had prenatal exposure to similar amounts of cocaine were not more likely to suffer from the same problems, Virginia Delaney-Black, M.D., of Children’s Hospital of Michigan and colleagues found. The study results are published in the Journal of Developmental and Behavioral Pediatrics.

While no specific cause of the gender-specific findings was identified, the researchers note that the study confirms animal studies that also suggest gender plays a role in the effects of cocaine exposure.



Delaney-Black and colleagues say human studies have been "inconsistent" on the question of whether prenatal cocaine exposure has gender-specific effects on children’s development.

The study looked at 473 children in the Detroit area ages 6 to 7 whose mothers had received prenatal care and drug testing. About 200 of the children in the study were prenatally exposed to cocaine. Children were considered "persistently" exposed if they or their mothers tested positive for traces of cocaine in their urine at the time of birth.

To determine whether these children had a higher likelihood of behavioral and other cognitive problems, Delaney-Black and colleagues collected information on the children’s behavior from their teachers.

After accounting for other factors like violence in the home or neighborhood, parents’ income and marital status, boys who had been persistently exposed to cocaine in the womb had more behavioral problems and problems with abstract thinking and motor skills than those who had never been exposed to cocaine or those who had only some prenatal exposure to the drug.

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
