Organochlorines May Affect Infant Attention Skills
Author Information
Author(s): Tanya Tillett
Primary Institution: National Institute of Environmental Health Sciences
Hypothesis
Is there an association between prenatal exposure to organochlorines and attention skills in infants?
Conclusion
The study found that higher levels of organochlorines in infants' serum were associated with poorer attention skills.
Supporting Evidence
- Previous studies linked PCB exposure to attention deficits in older children and adults.
- 96% of serum samples had detectable DDE levels.
- The study used the Neonatal Behavioral Assessment Scale to evaluate infant attention.
Takeaway
Babies exposed to certain chemicals before birth might have trouble paying attention later on.
Methodology
Infants' attention skills were assessed using the Neonatal Behavioral Assessment Scale, and their cord serum was analyzed for organochlorine levels.
Limitations
The study acknowledges uncertainty in the NBAS's ability to predict future attention behaviors.
Participant Demographics
Infants born between 1993 and 1998 to mothers living near a PCB-contaminated harbor.
