African-American infants at increased risk from tobacco smoke exposure

04.05.2010
Low levels of prenatal tobacco smoke exposure are associated with a higher risk of developmental problems for African American children than white children, according to new research from Cincinnati Children's Hospital Medical Center.

The findings were presented at noon ET Saturday, May 1, at the annual meeting of the Pediatric Academic Societies in Vancouver, Canada.

Prenatal exposure to tobacco smoke has already been linked to prematurity and cognitive defects in young children. Previous research has also shown racial differences in metabolism of nicotine among adolescents, adults, and pregnant women. The current study focused on the developmental differences between 242 white and black children at 1 and 2 years of age. The study was limited to children whose mothers had measureable levels of cotinine – a biological byproduct of nicotine – in their blood during pregnancy.

"We found that low-level prenatal tobacco exposure was associated with deficits in both motor and cognitive development, but only for black children," said Kimberly Yolton, Ph.D., a developmental psychologist in the division of General and Community Pediatrics at Cincinnati Children's and lead investigator on the study.

The children were assessed for cognitive and motor development using The Bayley Scales of Infant Development (Second Edition). Although the researchers found no statistically significant association between prenatal tobacco exposures and lower scores in white children, Dr. Yolton stressed expectant white mothers should still refrain from smoking.

"All women should be aware of the dangers of tobacco smoke to themselves and their developing babies, but our research suggests African American women should be particularly careful during pregnancy," Dr. Yolton said.

Interestingly, although only 30 percent of mothers in the study reported any exposure to tobacco smoke – either by smoking themselves or through second-hand exposure – all had measurable cotinine levels in their blood. Dr. Yolton said this indicates expectant mothers and their children may be at risk of exposure even when they don't realize it.

"And when pregnant mothers do smoke, the nicotine easily passes through the placenta to the developing baby, and nicotine concentrations are 15 times higher in the baby's blood than the mother's," she added.

Dr. Yolton said future research efforts are aimed at better understanding the metabolic and molecular reasons for tobacco smoke's harmful affects on infants and children as well as the racial disparities associated with exposure.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
