Infants' Environmental Health Study (ISA)
The ISA study aimed to investigate the potential effects of prenatal exposure to pesticides and manganese on children’s growth and neurodevelopment. Between 2010 and 2011, the study recruited 451 women who were at least 15 years old, less than 33 weeks pregnant, and lived at least 5 km from a banana plantation in Matina County, Costa Rica. The women were assessed one to three times during pregnancy, and approximately seven weeks postpartum. Infant data was collected from medical records at birth, and the women-infant pairs were further assessed at approximately one year and five years postpartum.
