Study Finds Higher Rates of Premature Birth Near Fracking Sites (jhsph.edu) 131

Posted by Soulskill from the now-with-improved-gestation-speed! dept.
An anonymous reader writes: Researchers from the Johns Hopkins Bloomberg School of Public Health have published a study (abstract) noting that pregnant women are more likely to give birth prematurely if they live close to fracking sites. The researchers used data from 40 counties in Pennsylvania, in which 10,946 babies were born between January 2009 and January 2013. They compared the data with the fast spread of fracking sites across the state — thousands have been built since 2006.

"The researchers found that living in the most active quartile of drilling and production activity was associated with a 40 percent increase in the likelihood of a woman giving birth before 37 weeks of gestation (considered pre-term) and a 30 percent increase in the chance that an obstetrician had labeled their pregnancy "high-risk," a designation that can include factors such as elevated blood pressure or excessive weight gain during pregnancy. When looking at all of the pregnancies in the study, 11 percent of babies were born preterm, with the majority (79 percent) born between 32 and 36 weeks."

There are enough areas now to measure water quality and other factors and make a good measurements on what pollutants are out there.

        Just a couple month ago the USEPA completed a multi-year study of fracking in several areas of the US, which found no risk to groundwater quality.

    I'm not a shill for the fracking industry. However, a question comes to my mind: Is it possible that it is not the fracking itself, but the stress of knowing that you live near the fracking?

    I wonder if they could model this with mice just to get a little more info on the effects of fracking pollutants.

        I was wondering the same thing. There usually isn't a lot of fracking in urban affluent areas. It tends to be in rural areas that are much poorer than what you would find in even the below average income areas of a city. Plus access to medical care is considerably less in those areas too.

      1: No mention of prior healthcare records from the subjects studied. If a large portion of the subjects didn't have healthcare prior to gas and oil field work provided insurance it will definitely impact how the pregnancy progresses. There was also no mention of what, if any, jobs these women were performing during pregnancy, how many drank alcohol or consume

    I'm not discounting the possibility that there may be a causal relationship here but from what I see of the article and abstract they only looked at data between 2009 and 2012. Is it possible that these sites have a preexisting condition that would cause higher levels of preterm birth? They should expand their data analysis to a larger period before the fracking occurred. This way we can at the very least see if there is a stronger correlation here and move forward.

  • I suppose fracking can happen at random places. However, most of the land area in the US is characterized by lower than average socioeconomic status, as expressed on a per capita basis, for the simple reasons that cities tend to have higher population and higher per capita income. This way, even a random site selection leads to a bias in the welfare of the neighboring population. Add to this that fracking is more restricted in and around large cities.

    While the study may have accounted for these factors, the
