Interventions

  • Intensive Public Health Campaign — BEHAVIORAL
    A comprehensive intervention including: (1) three interactive community workshops on lead risks and prevention, (2) distribution of tailored educational materials, (3) provision of lead-safe cleaning kits (HEPA vacuums, cleaning supplies), and (4) two home visits by trained health educators to reinforce messages and assess household practices.

  • Standard Information Dissemination — BEHAVIORAL
    Provision of standard municipal information on lead exposure prevention, including pamphlets and website links, as currently distributed by public health authorities. No additional workshops or home visits provided.

Study Details

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.
