A new study has revealed that higher glyphosate levels were associated with lower birth weight and may also lead to higher neonatal intensive care unit admission risk.
The study was published in the journal, ‘Environmental Health’.

This is the second small-scale study the researchers have conducted with significant findings. The team’s previous study, published in 2018, was the first study to confirm glyphosate in 93 per cent of pregnancies which found associations with shortened pregnancies. Other recent studies have also confirmed their findings.
“Pesticide exposure in pregnancy, especially in early pregnancy, can imprint DNA and alter gene expression,” said Paul Winchester, MD, professor of clinical paediatrics and the study’s lead author. “But little is known about how these chemicals can impact fetal development in humans.”
Glyphosate is a chemical, commonly found in Roundup, used to kill weeds. It is used by farmers and homeowners across the United States, but especially in the Midwest on corn and soybeans. Previous studies have shown people can be exposed to glyphosate in all the foods they eat, even packaged or organic foods.
Over the course of several years, researchers observed a cohort of 187 pregnant women in Indiana, collecting urine samples in the first trimester of their pregnancies. All but one of the women had glyphosate detected in their urine.
Winchester said previous studies had shown a variety of negative effects of pesticide exposure in animal models, but not much is known about the impact on fetal development in humans.
“As a neonatologist, I’m seeing more and more infants with problems like low birth weight as well as mothers with issues like obesity or gestational diabetes,” Winchester said. “We need to keep studying these herbicides long term to find out how they could be causing these issues and what we can do to prevent them.”
Researchers hope to study glyphosate exposure in a larger group of pregnant women over time.
