Overview One of the most preventable childhood health problems Children susceptible due to rapid G & D and hand to mouth behavior ¼ of the nation’s children are exposed at home 400,000 children nationwide are lead-poisoned each year Principle source: lead-based paint NYS Physicians are required to test Current emphasis: primary prevention

History of NCDOH CLPPP 1970’s-CDC grant to identify children with lead poisoning, 9 positions, assigned to community testing 1980’s -  funding, 1 employee, case management Late 1980’s - grant from NYSDOH-case management and Head Start testing 1990’s – present - expanded grant from NYSDOH – expanded case management, education, environmental assessment 1992 – Public Health Campaign – laboratory development for lead testing

CDC Acceptable BLL Table 1. Changing definitions of acceptable blood lead levels in the United States Year Level of Concern mcg/dL mcg/dL mcg/dL mcg/dL mcg/dL 2004 Discussions underway at CDC to determine if level should be further decreased to 5 mcg/dl, in light of growing body of research demonstrating no "safe" threshold of exposure

NYS Lead Law 1993 Mandated testing at ages 1 and 2 years Annual assessment to age 6 years Test if + risk assessment All BLL reportable to LHU/database LHU-identify and track children, assure f/u LHU-provide environmental management Obstetricians required to screen pregnant women
