Linking Lead Exposure to Risk Factors

What is the problem?

Childhood exposure to lead is a concern because it can cause developmental disabilities. Iowa has elevated child blood lead levels (BLLs) above the national average. Data from the Centers for Disease Control and Prevention show that between 2003 and 2007 more than 4,700 Iowa children had blood lead levels that were 10 micrograms per deciliter (µg/dl) or higher.

What did Tracking do?

The Iowa Tracking Program will work with the state's Childhood Lead Poisoning Prevention Program to conduct a data-linkage project. The project will study the links between childhood blood lead levels and risk factors such as poverty level, race, ethnicity, and age of housing.

Improved public health

Knowing what risk factors are related to childhood lead poisoning will help the Iowa Department of Public Health and others deliver resources and interventions to the citizens who are most at risk. This will help Iowa lower the number of children with elevated blood lead levels in the state.
