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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
