Surprising Findings
Higher PFHxS exposure wasn’t linked to worse behavior — only medium exposure was.
We usually expect a dose-response relationship: more chemical = worse outcome. But here, the effect peaked in the middle and disappeared at the highest levels, which contradicts intuition and some prior research.
Practical Takeaways
Don’t panic if you’ve been exposed to PFAS during pregnancy — it’s unlikely to cause behavioral issues in your child.

Exposure to certain chemicals during pregnancy doesn’t seem to consistently affect kids’ behavior or emotions as they grow up, based on a big U.S. study tracking moms and their children.
Exposure to certain 'forever chemicals' during pregnancy doesn't seem to affect kids' behavior problems like anxiety or aggression, based on a large U.S. study tracking moms and their children.
Pregnant moms' exposure to certain 'forever chemicals' (PFOS, PFOA, PFNA) doesn't seem to affect their kids' behavior problems — like anxiety, aggression, or overall emotional issues — as they grow up to age 15.
In a big U.S. study, boys and girls seemed equally affected by mom's exposure to PFAS chemicals during pregnancy when it comes to behavior problems — there's no clear difference between them.
These man-made chemicals stick around in the environment and in our bodies, and they might be harming our health — possibly leading to problems like trouble having kids, birth issues, liver disease, weak immune systems, and even cancer.
