Lead levels among children who live in public housing

Exposure to lead hazards is a serious health concern for inner-city children. In the United States, the greatest contributor to an elevated lead level is lead exposure in the home. There are federal regulations to protect children in public housing developments from exposure to lead paint. The efficacy of these regulations has not been examined.

We assessed the association between residence in a public housing development and the risk of an elevated blood lead level among high-risk children in New Orleans. We did so by conducting a case-control study among 7121 children age 6 to 71 months who received a screening blood lead test from New Orleans public health clinics in 1998.

We found elevated blood lead levels for 29% of children who were screened. Children residing in New Orleans housing developments had lead levels no different from those residing in nondevelopment housing when controlling for housing age, and child's sex and age (odds ratio = 0.93; 95% confidence interval = 0.77-1.1).

Despite legislative efforts, public housing does not appear to protect children from elevated lead levels, calling into question the efficacy of existing regulations.
