A Study to Assess the Efficacy of Public Health Campaigns in Reducing Lead Exposure
Sponsor: International Health Strategies LLC
Summary
This clinical trial aims to evaluate the effectiveness of targeted public health campaigns in reducing lead exposure among adults living in urban communities with known environmental lead hazards. Lead exposure remains a significant public health concern, particularly in older urban neighborhoods with aging infrastructure and legacy contamination. Despite existing regulations and remediation efforts, many communities continue to experience elevated blood lead levels, especially among vulnerable populations. The study will compare the impact of an intensive, multi-modal public health campaign-featuring community workshops, educational materials, and home intervention resources-against standard municipal information dissemination. By assessing changes in blood lead levels and lead-related knowledge, attitudes, and behaviors over a 12-month period, the trial seeks to determine whether enhanced public health outreach can more effectively reduce lead exposure and promote safer practices. The findings will inform future strategies for community-based environmental health interventions.
