Chinese mothers who were exposed to a high level of certain air pollutants during pregnancy had a higher risk of abnormal fetal growth, according to a new Yale School of Public Health (YSPH) study.

The findings, published in the International Journal of Epidemiology, were based on data collected from more than 8,000 women in Lanzhou, China from 2010 to 2012.

The researchers said that, to their knowledge, it is the first study of its kind to be conducted in areas with very high air pollution levels.
