Tobacco and Substance AbuseSecondhand Smoke Exposure Reduction After NICU Discharge: Results of a Randomized Trial
Section snippets
Participants
We enrolled infants born at ≤32 weeks' gestational age, along with their caregivers, into a randomized controlled trial within 6 weeks of their discharge from the neonatal intensive care unit (NICU) at Golisano Children's Hospital in Rochester, New York. Families were recruited in-person in the NICU or over the phone after discharge from March 2007 to May 2011; 165 infants were enrolled. Exclusion criteria included caregiver age <16 years, infants with serious medical comorbidities that could
Results
We collected postintervention survey information for 144 caregivers (87%) and saliva samples from 132 infants (80%). Participating premature infants were 59% male, 35% Black, 19% Hispanic, and 61% used Medicaid as their primary insurer at enrollment; 45% of infants were born <28 weeks' gestational age, and 58% were delivered via cesarean section. Caregivers were mostly mothers of enrolled infants (98%), single (59%) and <30 years (53%); 27% did not finish high school. At enrollment, 26% of
Discussion
Our intervention had a positive impact on short-term infant SHS exposure when compared to brief asthma education alone. MI counseling along with asthma education close to the time of NICU discharge was associated with reduced caregiver-reported SHS exposure. At the follow-up survey 5 months after NICU discharge, significantly fewer infants in the intervention group had routine contact with smokers. We also found a higher prevalence of home smoking bans and total smoking bans reported by
