Response: Childhood lead poisoning continues to be a problem in the United States and residential lead hazards are the major source of Pb exposure in young children.

Thus, we randomized 355 pregnant women to a comprehensive residential intervention and followed their children for up to 8 years to determine if childhood lead poisoning and associated cognitive deficits and behavior problems can be prevented.

Response: Lead exposure among children is linked to many adverse effects on health and cognitive development, which can be irreversible. The National Center for Health Statistics (NCHS) has linked 1999 to 2012 National Health and Nutrition Examination Survey (NHANES) data to administrative data for the Department of Housing and Urban Development’s (HUD) largest rental assistance programs (1999 through 2014), and these linked data allow calculation of the first-ever national blood lead level estimates among children living in HUD-assisted housing. Here we compare blood lead levels among children 1 to 5 years of age in 2005 to 2012 who received housing assistance during 1999 to 2014 with levels among children who did not receive housing assistance during that period.
