CINCINNATI - Researchers have uncovered new information about the effects that air pollution can have on your unborn baby.
The study published in the journal of Environmental Health Perspectives found a mother's exposure to air pollution may increase the risk of giving birth to an underweight child. Researchers concluded that the risk of being born underweight increases 3 percent for every 10 micrograms per cubic meters of pollution in the air.
The study analyzed data on 3 million pregnancies, making it the largest analysis yet looking at the relationship between air pollution and birth weight. Low birth weight can cause developmental delays or increase a baby's risk for infection.
Last year , a report by the American Lung Association ranked the Cincinnati area ei gh th in the nation for the worst air particle pollution.
