Proximity to hydraulic fracturing sites linked with adverse birth outcomes: JAMA
World Birth Defects Day
Canada: Individuals exposed to hydraulic fracturing throughout their pregnancy may be at a greater risk of a variety of negative birth outcomes, says an article published in the Journal of American Medical Association - Pediatrics.
The relationship between human development and hydraulic fracturing is unclear. Several studies have found a link between unconventional natural gas production and poor birth outcomes; however, geology and regulation differ by area. As a result, Zoe F. Cairncross and colleagues undertook this study to assess the overall relationship between hydraulic fracturing sites to residential proximity and bad birth outcomes, as well as whether well density altered this correlation.
From 2013 to 2018, this population-based retrospective cohort study of pregnant women in rural Alberta, Canada, was conducted. Participants were women of reproductive age (18-50 years) who had a pregnancy between January 1, 2013, and December 31, 2018, and resided in rural regions. Individuals were omitted if they resided in a city, were beyond the age limit, or had missing information on newborn gender, postal code, or area-level socioeconomic position. The Alberta Energy Regulator (n = 4871) identified oil and gas wells which underwent hydraulic fracturing between 2013 and 2018. Individuals were deemed exposed if their postal delivery point was within 10 kilometers of one or more hydraulically fractured wells during the one-year preconception period or during pregnancy.
