Utilizing Biomarker Feedback Documenting Child Exposure to Tobacco Toxins to Promote Smoke-Free Homes: Study Protocol for a Randomized Clinical Trial (Preprint)

Background Exposure to secondhand smoke (SHS) early in life increases the risk of sudden infant death syndrome (SIDS), asthma, and respiratory illnesses. Since children’s primary exposure to SHS occurs in the home, these most vulnerable members of our society are not fully protected by recent increases in the adoption of smoking bans in public spaces. Although exposure to SHS is a quickly reversible cause of excess morbidity, few low-income homes strictly enforce smoking restrictions.
