Abstract
OBJECTIVES:
We tested the effectiveness of a community-based lay health advisor intervention for primary prevention of lead poisoning among Native American children who lived in a former mining area.
METHODS:
We conducted cross-sectional population-based blood lead assessments of Native American and White children aged 1 to 6 years and in-person caregiver interviews before (n=331) and after (n=387) a 2-year intervention.
RESULTS:
Mean childhood blood lead levels decreased and selected preventive behaviors improved for both Native American and White (comparison) communities. Several short-term outcomes also improved from pre- to postintervention, but only knowledge and hand-washing self-efficacy increased more among Native Americans than among Whites.
CONCLUSIONS:
Our findings provide limited support for the effectiveness of lay health advisor interventions as a primary lead poisoning prevention strategy for Native American communities.
