OBJECTIVE: In a two-group prospective design, this study compares seasonal cholinesterase levels of Latinx children in rural farmworker families and comparable urban children, to assess the impact of environmental exposure to cholinesterase-inhibiting insecticides.

METHODS: Quarterly blood samples and passive dosimeter wristbands were collected over 2 years in 8 year old children (74 rural, 62 urban). Laboratory analysis assessed total cholinesterase (total ChE), acetylcholinesterase (AChE), and butyrylcholinesterase (BChE) from blood samples, and insecticides from wristbands.

RESULTS: In spring and summer, total ChE and AChE levels were depressed in rural children compared to winter and fall. BChE was depressed in rural children in fall, compared to spring and summer. Adjustment for insecticide exposure did not affect these associations.

CONCLUSIONS: Environmental exposures to cholinesterase-inhibiting insecticides have measurable biochemical effects on blood cholinesterases in rural children from farmworker families.
