Objective

We assessed the screening and remediation of home lead hazards prenatally in a high-risk population, hypothesizing that average blood-lead level and the number of poisonings would drop by 25 % .

Study Design

One hundred fifty-two women underwent prenatal home inspections by certified lead inspectors. The hazards that were identified were remediated. The blood-lead levels of children of participating women were compared with matched control subjects.

Reuslts

Blood-lead levels were obtained from 60 children and compared with matched control subjects. The average blood-lead level of children in the treatment group was 2.70 ¦Ìg/dL vs 3.73 ¦Ìg/dL in control subjects (P = .019). The percentage of children with levels >10 ¦Ìg/dL in the treatment group was 0 % vs 4.2 % in control subjects (P = .128).

Conclusion

Screening and remediation of houses of pregnant women is effective to reduce the average blood-lead level and number of children that exceed the federal level of concern for lead poisoning in a high-risk population.
