Objective:
To develop a spatial strategy to assess neighborhood risk for lead exposure and neighborhood-level blood lead testing of young children living in the city of Atlanta, Georgia.
Study Design:
This ecologic study used existing blood lead results of children aged
Results:
In 2005, only 11.9% of Atlanta's 18,627 children aged
Conclusions:
This neighborhood spatial approach provided smaller geographic areas to assign risk and assess testing in a city that has a high prevalence of risk factors for lead exposure. Testing may be improved by collaboration between pediatricians and public health practitioners.
