And, like many other public health issues, affected populations tend to be concentrated in low-income areas home to large numbers of minorities.
"This is another piece of the evidentiary pie about why we should really be doing something about air pollution," says Tracey Woodruff, a professor who studies reproductive health and the environment at the University of California, San Francisco.
"When you reduce air pollution you get lots of different health benefits."
Countless studies have shown the effect of air pollution on cardiovascular and respiratory health -- killing millions each year. Air pollution leads to inflammation in blood vessels and contributes to lung cancer, asthma and a slew of other disorders.
The effect on pregnancy may in some ways be an extension of those effects as air pollution disrupts the way a pregnant woman delivers oxygen to the fetus.
Air pollution may also disrupt the endocrine system, keeping women from producing a protein needed to regulate pregnancy, researchers say.

Transmitters have been strategically placed on portions of the Jet Stream flow in order to evaporate the moisture as it moves into Southern CA.
Chemtrail aerosols were sprayed all day over the Southern CA region and more importantly, over the Colorado River extending from Nevada all the way to Mexico.
A huge blanket of aerosols is visible over the Colorado river where many dams and reservoirs are located. Those aerosols have stopped the opportunity for precipitation over the river.
There is a separate transmitter generating heat on the core of the low pressure system now over Southern CA.
This condition has been generating strong winds between the offshore high, and the low pressure area over CA.
The high pressure zone that has been installed and parked in the East Pacific for the past 11-12 days is now winding the cold front from the North Pacific storm clockwise and down into CA.
A square feature from a phased array radar is visible on the core of the North Pacific storm, and its associated cold front has been disconnected from the weather system as a result of the constant radar-generated heating.
