Living near oil and gas wells linked to low birthweight in babies

Risk is greater in rural areas, according to study of nearly 3 million births over 10 years

Living near active oil and gas wells during pregnancy increases the risk of low-birthweight babies, especially in rural areas, according to the largest study of its kind.

Researchers analysed the records of nearly 3 million births in California to women living within 6.2 miles (10km) of at least one oil or gas well between 2006 and 2015. It is the first such study to look at birth outcomes in rural and urban areas, and to women living near active and inactive oil and gas sites.
