During 1991-1994, an estimated 930,000 U.S. children aged < 6 years had blood lead levels (BLLs) > or = 10 micrograms/dL, and the risk for an elevated BLL was greatest among children who were non-Hispanic black or Mexican American, from low-income families, living in large metropolitan areas, or living in housing built before 1946. Because risk for lead exposure is associated with several different factors, it can vary greatly across relatively small areas. To establish the local prevalence and distribution of childhood lead exposure and develop local blood lead screening recommendations, the Salt Lake City-County Health Department (SLCCHD) offered free blood lead screening to all children aged 12-36 months enrolled at the seven Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) clinics in Salt Lake County, Utah (1995 population: 812,000), during January-October 1995. This report presents findings of the screenings at WIC clinics, describes the design and promotion of local targeted screening recommendations, and describes the resulting increases in appropriate BLL screenings among children.
