The Local Problem Natalie Colabianchi, Ph.D. Chris Kippes, M.S. Mireya Diaz-Insua, Ph.D. Alfred Rimm, Ph.D. Jessica Diggs In cooperation with: Cuyahoga County Board of Health Cleveland Department of Public Health
Background • Lead poisoning may be the most significant environmental problem facing our children • Nationally and locally, lead levels in children have been decreasing dramatically over the past 20 years • Much of the decline is due to the removal of lead from gasoline • Rates remain high in urban areas and in poor communities • Steep rates of decline not likely to continue
Cuyahoga County relative to other counties in Ohio EBLL (10 mg/dL +) • Cuyahoga 17% • Hamilton 7% • Franklin 2% • Lucas 11% • Mahoning 14% • Summit 1%
Estimated Number of Children with Elevated Blood Lead Levels (EBLL) City Est. Children w/EBLL (10 mg/dL +) • New York, NY 41,100 • Chicago, IL 20,600 • Los Angeles, CA 15,000 • Detroit, MI 12,800 • Philadelphia, PA 11,400 • Baltimore, MD 6,300 • Houston, TX 6,300 • Cleveland, OH 5,100 • New Orleans, LA 4,700 • Milwaukee, WI 4,600
Cleveland relative to other cities in Ohio EBLL (10 mg/dL +) • Cleveland 20% • Cincinnati 7% • Columbus 2% • Toledo 12% • Youngstown 16% • Akron 2%
Local Data • Years 1997 - 2000 • 130,190 tests representing 82,396 children • 33% of children had more than one test • Included only children less than 6 years of age • Children across the years: • 28404 children tested in 1997 • 27603 children tested in 1998 • 24371 children tested in 1999 • 23441 children tested in 2000
Sampling • Data come from mandatory reporting; Not a random sample • Proportions are influenced by rates of testing, who is tested and requirements for testing • Cleveland is considered a universal screening area • Medicaid population also mandated to be tested • Other high risk zip codes in Cuyahoga County with universal designation
Defining a confirmed test • Venous tests are confirmed tests • Capillary tests under 10 mg/dL are confirmed tests • Capillary tests with results of 10 mg/dL or higher need a second test within the CDC guidelines to be confirmed • Other tests were deemed unconfirmed and child was consider not elevated
Analyses • Proportion of children with EBLL • In year 2000 • Across census tracts • Trends from 1997 to 2000 • Demographic correlates • Neighborhoods and municipalities with high proportions of elevated children • Average levels over time • Multiple children in a household • Numbers of children tested
Proportion of children with EBLL in year 2000 • In Cleveland, 20.3% of children, one out of five, have blood lead levels that are elevated (e.g., 10mg/dL or higher) • In Cuyahoga County, 8.5% of children have blood lead levels that are elevated (e.g., 10 mg/dL or higher)
