Preterm births were 40 percent higher among women who lived in areas of intense drilling and fracking operations, and these women's pregnancies were 30 percent more likely to be considered "high-risk," the authors found.
Being born premature is linked to breathing problems, cerebral palsy, and hearing and vision impairments. In addition, preterm-related causes of death are the single leading cause of infant deaths, the CDC reports, accounting for 35 percent of infant deaths in 2010. Preterm birth can cause long-term neurological disabilities.
A new study from the Johns Hopkins Bloomberg School of Public Health has linked hydraulic fracturing — the process of pumping chemical-laced water into shale to extract the oil or gas embedded within — to premature births and high-risk pregnancies.
