US study links pollution to autism risk

WASHINGTON – Pregnant women who were exposed to high levels of air pollution were twice as likely to have a child with autism as women who lived in low pollution areas, a US study said on Tuesday.

According to experts at Harvard University, the research is the first large national study to examine links between the prevalence of pollution and the development of the developmental disorder.

The findings are published in the journal Environmental Health Perspectives.

“Our findings raise concerns,” said lead author Andrea Roberts, a research associate in the Harvard School of Public Health Department of Social and Behavioral Sciences.

“Depending on the pollutant, 20 percent to 60 percent of the women in our study lived in areas where risk of autism was elevated,” she said.

The data came from a large survey of 116,430 nurses that began in 1989.

For the analysis, researchers isolated 325 women who had a child with autism and 22,000 women who had a child without the disorder.

To estimate exposure to pollutants while pregnant, they used air pollution data from the Environmental Protection Agency, and adjusted for factors like income, education, and smoking during pregnancy.

The analysis found that women who lived in locations with the highest levels of diesel particulates or mercury in the air were twice as likely to have a child with autism as those who lived in the areas with the lowest levels.

When the pollutants included lead, manganese, methylene chloride and combined metal exposure, women in areas with the highest levels of these pollutants were about 50 percent more likely to have a child with autism.

Autism is a brain disorder that affects as many as one in 88 in the United States, and about one in 100 in Britain.

Researchers said the findings suggest that metals and other pollutants should be regularly measured in the blood of pregnant women to give a better understanding of whether certain pollutants increase autism risk.

      Chong magkaiba ang autism at Down syndrome (mongoloid). Although agree ako, nagiging normal na ngayon sa China ang pagiging abnormal.
