Hypothesis
How do cord and maternal blood mercury levels affect child developmental outcomes?
Conclusion
Cord blood mercury levels were associated with reduced cognitive function in children at ages 3 and 4.
Supporting Evidence
- Cord blood mercury levels were linked to cognitive function at ages 3 and 4.
- The study controlled for various factors including maternal IQ and environmental exposures.
- Breast-feeding status did not significantly affect the developmental outcomes related to mercury exposure.
Takeaway
The study looked at how mercury in the blood of pregnant women and their babies affects how well kids think as they grow up.
Methodology
The study measured blood mercury levels in mothers and their children and assessed cognitive function at ages 1 to 4.
Potential Biases
There may be risks of bias related to the selection of the cohort and the measurement of variables.
Limitations
The study may not account for all potential confounding factors affecting cognitive development.
Participant Demographics
Participants were mothers who were pregnant during the World Trade Center disaster and their children.
