Researchers identify association between pollution and behavioral problems

By Staff Writer

Women who are exposed to high levels of air pollution during pregnancy may be more likely to have kids with behavioral problems, according to a recent study published in the journal Environmental Health Perspectives.

The researchers explained that pollutants are created when fossil fuels or organic materials are not fully combusted. Common sources of pollution include car exhaust and cigarette smoke, they said.

The investigators also noted that when mothers-to-be inhale these particles, they can be transferred to a baby's DNA.

Years after measuring for biomarkers of pollutants in umbilical-cord blood samples from 215 babies, the researchers questioned parents about their kids' behaviors. The scientists then compared the results of the tests and surveys in order to identify any potential patterns.

The results showed that children who had high levels of a pollution exposure marker in their cord blood were more likely to experience symptoms of attention problems, anxiety or depression when they were between the ages of 5 and 7 than those with low pollutant readings.

Kids who suffer from these disorders may struggle to achieve good grades or form bonds with their classmates. Boarding schools may help young children cope with mental or learning disabilities.
