What is a significant risk factor for lead absorption in children?

Lead absorption in children is influenced by various significant risk factors. A low dietary intake can increase the risk as inadequate nutrition, particularly a deficiency in calcium and iron, can make children's bodies more susceptible to absorbing lead. When children have insufficient amounts of these nutrients, their bodies may absorb lead more readily, amplifying the health risks associated with lead exposure.

Exposure to contaminated water is also a crucial factor. Lead can leach into drinking water from lead pipes and plumbing fixtures. Consuming this contaminated water can lead to significant lead exposure, especially in young children whose developing bodies can be impacted more severely by lead toxicity.

Proximity to lead paint is likewise a strong risk factor. Homes built before 1978 are more likely to contain lead-based paint. Children living in or frequently visiting such homes can be exposed to lead dust or chips, particularly if the paint is deteriorating, which poses a direct health risk.

Since each of these factors—poor diet, contaminated water, and proximity to lead paint—individually raises the risk of lead absorption, it is accurate to conclude that all of the options collectively represent significant risks that contribute to lead exposure in children.
