This is a population-based
case-control study of risk factors for Attention
Deficit/Hyperactivity Disorder in semi-rural Johnston County, North
Carolina. Four hundred teachers will be asked to fill our brief
behavior checklists on all students in their classes. We expect
that 900 of these children will be eligible as cases or controls
for detailed parent interviews about the child's behavior at home,
family history, and exposures to the mother during pregnancy. Shed
baby teeth will be collected in year 2 to measure lead levels.
Buccal swabs will be collected from family members in year
2.
