This prospective environmental intervention study was conducted to determine the impact of low-technology lead hazard reduction activities among children with mildly elevated blood lead levels. Children whose homes had severe lead hazards were automatically assigned to the intervention group. Children whose homes had lesser hazards were randomly assigned to the intervention group or comparison group. The one-time intervention focused mainly on cleaning and repainting window areas and educating caregivers to maintain effective housekeeping techniques. Changes in blood lead and dust lead loading levels were observed following the interventions. Analysis of covariance was used to adjust comparisons of postintervention levels for preintervention levels and other variables. The lead hazard reduction activities were associated with a modest decline in blood lead levels among children with severe hazards. The magnitude of the decline depended on the confounder that was controlled; the majority ranged from {minus}1.1 to {minus}1.6 {micro}g/dL. A moderate reduction in window well dust lead loading levels was also observed. While low-technology lead hazard reduction measures appeared to be an effective secondary prevention strategy among children with severe household lead hazards, larger studies are needed to confirm these results.
