New research shows that significant exposure to organic pollutants early on in pregnancy is associated with a big uptick in gestational diabetes.
Specifically, the study showed that a 10-times increased exposure to so-called "persistent organic pollutants," known as POP, in the first trimester correlated to a 4.4 times increased risk of the disorder.
POP is a group comprised of various substances—synthetic chemicals used broadly as pesticides and in industrial processes—that don't biodegade, and show up nearly everywhere in the environment. Exposure to them has already been linked to type 2 diabetes in other studies, but not much was known about how they impact pregnancy. The use of these chemicals has long been banned, but they remain stubbornly in the environment, where they accumulate in animals' bodies and our own bodies.
Researchers indicate that further studies are needed to replicate these results and to further evaluate the associations. The study was presented at the European Association for the Study of Diabetes in Stockholm.
