Query Builder for Query Module for Childhood Lead Risk Factors - Housing Units Built Before 1950 - Percent of Housing Units Built Before 1950


Lead is a naturally occurring metal in the earth's crust. It was once used in paint and gasoline and is still used in batteries, solder, pipes, pottery, and roofing materials. Lead-based paint for homes, children's toys, and household furniture was banned in the U.S. in 1978, but lead-based paint is still on walls and woodwork in many older homes or apartments. Most lead poisoning in children is a result of eating chips of deteriorated lead-based paint. Young children may also be exposed to lead if they come in contact with dust or soil that contain lead due to increased time on the floor, and increased hand to mouth behavior. Children under the age of 6 absorb more lead than those over the age of 6.

Lead poisoning can be hard to detect. Signs and symptoms of lead poisoning in children include stomach or abdominal pain, vomiting, constipation, fatigue, developmental delay, learning difficulties, irritability, loss of appetite, weight loss, hearing loss, and seizures. However, most lead-poisoned children are not symptomatic. Signs and symptoms do not usually present until dangerous amounts have been accumulated within the body.

The only way to diagnose lead poisoning is to test blood levels. Major risk factors for childhood lead poisoning include living in housing that was built before the year 1950 and living with a below poverty-level income family. Studies have documented low blood-lead testing rates among children living in households with these risk factors.

This query's data identifies counties where children who may be at increased risk for lead poisoning are living. This query displays the percentage of homes that are built before 1950. It can be used to help guide intervention efforts to identify areas where children may be at increased risk for lead poisoning.
