Premature infants have a significantly increased risk for developing respiratory illnesses and asthma. Secondhand smoke (SHS) also is clearly associated with increased breathing problems in children, thus exposure to smoke makes it substantially more likely for a premature infant to develop wheezing. The overall goal of this study is to test whether comprehensive asthma education combined with a home-based secondhand smoke reduction program can reduce exposure to smoke and prevent respiratory illness among premature infants. Our hypotheses are:

  • More premature infants whose families receive asthma education combined with a SHS reduction intervention will live in smoke-free environments compared to infants receiving only asthma education (control group).
  • Caregivers receiving the SHS reduction program will have higher rates of quit attempts and less relapse into smoking compared to caregivers in the control group.
  • Infants whose families receive the combined intervention will experience less respiratory illness compared to infants in the control group.

Arms Assigned Interventions
Experimental: Secondhand Smoke Reduction and Asthma Education
Parents of children in the experimental group will receive asthma education at NICU discharge as well as a secondhand smoke reduction program.
Behavioral: Secondhand Smoke Reduction and Smoking Cessation Counseling
A secondhand smoke reduction program, including smoking cessation counseling (if appropriate), and feedback about the children's cotinine levels will be implemented using principles of Motivational Interviewing.
Behavioral: Asthma Education
Asthma education will be provided at NICU discharge.
Active Comparator: Asthma Education
Parents of children in the active comparator group will receive asthma education at NICU discharge.
Behavioral: Asthma Education
Asthma education will be provided at NICU discharge.
