New Australian research published in the peer-reviewed journal Medesearch published in the peer-reviewed journal Med has reported an association between prenatal exposure to the plasticiser DEHP, changes in DNA methylation, and measures of autism- and ADHD-related symptoms in young children.

The research is an interesting contribution to understanding possible relationships between environmental exposures and neurodevelopment and warrants further investigation.

Unfortunately, some media coverage has moved well beyond what the study actually demonstrated. Reporting by 7NEWS and subsequently MSN has suggested a link between DEHP and children being “born with autism”, while 7NEWS prominently raised the prospect of the findings ultimately necessitating a “global health emergency”.

Such inflammatory framing risks confusing an observed statistical association with evidence of causation.

The study did not demonstrate that DEHP causes autism or ADHD. It did not measure clinical diagnoses of either condition, and the researchers themselves acknowledge that the children are currently too young to draw concrete conclusions.

VCA believes potentially important health research should be taken seriously—and communicated accurately. Our response examines what the study found, what it did not find, and what further evidence is needed before broader conclusions can reasonably be drawn. It also puts DEHP into the context of its changing use in contemporary Australian PVC products.
