A Controlled Trial of an Environmental Tobacco Smoke Reduction Intervention in Low-Income Children with Asthma was a randomized controlled trial that was implemented in 1996 in California to determine the effectiveness of a cotinine-feedback, behaviorally based education intervention in reducing environmental tobacco smoke (ETS) exposure and health-care utilization of children with asthma.
Participants included 87 ETS-exposed, low-income, predominantly minority children who were 3-12 years old and who were seen for asthma in the hospital's emergency, inpatient, and outpatient services departments.
The intervention included three nurse-led sessions (over approximately a 5-week period) in a hospital setting that employed behavior-changing strategies and basic asthma education. The sessions also incorporated repeated feedback on the child's urinary cotinine level.
The intervention significantly reduced asthma health-care utilization. Effects sizes for urine cotinine and proportion prohibiting smoking were moderate to large, but not statistically significant.
