What this Trial Is About

The Heartland Study is a prospective, observational study that will enroll up to 2,600 pregnant participants across the Heartland States in the U.S.. The objective of the Heartland Study is to address major knowledge gaps concerning the health effects of herbicides on maternal and infant health. The study is being conducted to evaluate the associations between environmental exposures to herbicides during and after pregnancy and reproductive health outcomes. The study is measuring multiple biomarkers of herbicide exposure among pregnant Midwesterners and their partners to evaluate associations with pregnancy and childbirth outcomes, epigenetic biomarkers of exposure, and child development.
