Which housing characteristic is indicated as a higher risk factor for lead exposure in children?

• A. Living in older housing
• B. New houses
• C. Houses painted with water-based paint
• D. Houses in rural areas

Answer: (A)

The main factor is the age of the home. Lead-based paint was commonly used until 1978, so houses built before then may still have lead paint on walls, trim, and other surfaces. When that paint gets chipped or worn, it can generate lead-containing dust or chips that children might put in their mouths, leading to exposure. Newer houses, built after the ban, are far less likely to contain lead-based paint, so their risk is lower. The fact that paint is water-based or that a house is in a rural area isn’t by itself a strong indicator of higher lead risk—the key signal is whether the home could have lead-based paint from its construction era.
