Perceived Synergistic Risk for Lung Cancer After Environmental Report-Back Study on Home Exposure to Tobacco Smoke and Radon

Purpose:To examine the short-term impact of a personalized environmental report-back intervention to reduce home exposure to tobacco smoke and radon on perception of synergistic risk for lung cancer. Radon-induced lung cancer is more common among those exposed to tobacco smoke.Design:Randomized controlled trial.Setting:Primary care clinics and a pharmacy waiting area at a University Medical Center in the Southeastern United States and community events.Participants:Five hundred sixty adult homeowners and renters (3-month follow-up, n = 334).Intervention:Personalized environmental report back.Measures:Single-item synergistic risk perception measure using 5-point Likert-type scale.Analysis:Change in synergistic risk from baseline to 3 months was evaluated using a generalized estimating equation model containing main effects of treatment group and time. Covariates in the model included age, gender, education, and home smoking status.Results:For treatment and control groups combined, there was a significant in...
