EXPERT REACTION: Living near fracking sites while pregnant could be bad for bub
Observational study: A study in which the subject is observed to see if there is a relationship between two or more things (eg: the consumption of diet drinks and obesity). Observational studies cannot prove that one thing causes another, only that they are linked.
People: This is a study based on research using people.
Canadian researchers have found a link between living near fracking sites while pregnant and issues with your baby's development. The team looked at close to 35,000 pregnancies over six years in Canada, and say that living for one year preconception and/or having a baby develop within 10km of at least one fracking site is more likely to have major congenital anomalies and be small for their gestational age. Additionally, the researchers found the risk of spontaneous preterm birth and being small for gestational age were increased in those living with 100+ wells in that 10km border. This kind of study cannot directly prove that the fracking caused the issues, but the researchers say that because their results were adjusted for numerous confounding issues, it might be a good idea to be wary around unconventional oil and gas development if you're intending on becoming pregnant.
