AHS-related research has been published in many peer-reviewed journals.


The Agricultural Health Study is funded by the National Cancer Institute and the National Institute of Environmental Health Sciences in collaboration with the US EPA and NIOSH. The AHS encourages researchers to collaborate with us to focus on specific health issues related to farming practices. These studies are designed to leverage the data collected from participants.

Collaboration Resources


More than 89,000 farmers and their spouses in Iowa and North Carolina have been involved in the AHS since 1993. Their involvement has provided, and continues to provide, the data that researchers need to help the current and future generations of farmers, and their families, live healthier lives.
