Smoke-Free Homes is funded by the NIH and Emory University, and is envisioned to assist with the development, evaluation, and dissemination of a smoke-free homes intervention through the existing national infrastructure.
Topic area(s): Health Disparities; Health Communications


The purpose of the proposed research is to develop, evaluate and disseminate a brief smoke-free homes intervention through the existing national infrastructure of 2-1-1. 2-1-1 is a nationally designated 3-digit telephone exchange, similar to 9-1-1 for emergencies or 4-1-1 for directory assistance, that links callers to community-based health and social services.


Due in large part to the remarkable progress in creating smoke-free environments in the U.S. over the past two decades, the home is now a primary source of exposure to secondhand smoke for both children and nonsmoking adults.  Secondhand smoke causes coronary heart disease and lung cancer in adults. In infants and children, it exacerbates asthma and causes SIDS, respiratory infections such as bronchitis and pneumonia, and otitis media.  Exposure to secondhand smoke remains relatively high for African Americans, children and low-income families.  Intervention research that identifies effective and practical strategies for reaching the minority of households that still allow smoking in the home have considerable potential to reduce the disproportionate burden of tobacco use on low-income families.

The proposed research has four specific aims: 1) Conduct formative research on intervention messages and materials for promoting smoke-free homes in low-income populations, applicable to both smokers and nonsmokers as household change agents; 2) Conduct a randomized controlled trial (RCT) in the Atlanta 2-1-1 service area to evaluate the effectiveness of a brief intervention to create smoke-free homes among 2-1-1 callers; 3) Conduct replication studies in Houston and North Carolina 2-1-1 systems to systematically test the intervention in varied populations and tobacco control climates and 4) Disseminate the research-tested smoke-free homes intervention through a variety of mechanisms.
