Prenatal exposure to organophosphate pesticides and IQ in 7-year-old children.

ABSTRACT:

Context

Organophosphate (OP) pesticides are neurotoxic at high doses. Few studies have examined whether chronic exposure at lower levels could adversely affect children's cognitive development.

Objective

We examined associations between prenatal and postnatal exposure to OP pesticides and cognitive abilities in school-age children.

Methods

We conducted a birth cohort study (Center for the Health Assessment of Mothers and Children of Salinas study) among predominantly Latino farmworker families from an agricultural community in California. We assessed exposure to OP pesticides by measuring dialkyl phosphate (DAP) metabolites in urine collected during pregnancy and from children at 6 months and 1, 2, 3.5, and 5 years of age. We administered the Wechsler Intelligence Sca
