Hypothesis
Does prenatal exposure to chlorpyrifos affect children's neurodevelopment?
Conclusion
Prenatal exposure to chlorpyrifos is linked to lower cognitive and motor skills in children.
Supporting Evidence
- The study found that children with higher prenatal exposure to chlorpyrifos had lower scores on mental and motor indices.
- Children exposed to chlorpyrifos showed more problems with attention deficits and hyperactivity.
- Animal studies have shown that chlorpyrifos causes developmental neurotoxicity.
Takeaway
Kids who were exposed to a pesticide before they were born may have trouble thinking and moving as they grow up.
Methodology
The study followed a cohort of inner-city minority women and their children, collecting biological samples and conducting developmental tests.
Potential Biases
Potential confounding variables were controlled for, but extrapolating animal study results to humans can be challenging.
Limitations
The long-term effects of chlorpyrifos exposure in children are still unknown.
Participant Demographics
Inner-city minority women and their children born between February 1998 and May 2002.
