IntroductionAddressing maternal smoking and child tobacco smoke exposure is a public health priority. Standard care advice and self-help materials to help parents reduce child tobacco smoke exposure is not sufficient to promote change in underserved populations. We tested the efficacy of a behavioral counseling approach with underserved maternal smokers to reduce infant's and preschooler's tobacco smoke exposure.DesignA two-arm randomized trial: enhanced behavior counseling (experimental) versus enhanced standard care (control). Assessment staff members were blinded.Setting/ParticipantsThree hundred randomized maternal smokers were recruited from low-income urban communities. Participants had a child aged <4 years exposed to two or more maternal cigarettes/day at baseline.InterventionPhiladelphia Family Rules for Establishing Smoke-free Homes (FRESH) included 16 weeks of counseling. Using a behavioral shaping approach within an individualized cognitive-behavioral therapy framework, counseling reinforced efforts to adopt increasingly challenging tobacco smoke exposure-protective behaviors with the eventual goal of establishing a smoke-free home.Main Outcome MeasuresPrimary outcomes were end-of-treatment child cotinine and reported tobacco smoke exposure (maternal cigarettes/day exposed). Secondary outcomes were end-of-treatment 7-day point-prevalence self-reported cigarettes smoked/day and bioverified quit status.ResultsParticipation in FRESH behavioral counseling was associated with lower child cotinine (β=-0.18, p=0.03) and reported tobacco smoke exposure (β=-0.57, p=0.03) at the end of treatment. Mothers in behavioral counseling smoked fewer cigarettes/day (β=-1.84, p=0.03) and had higher bioverified quit rates compared with controls (13.8% vs 1.9%, χ(2)=10.56, p<0.01). There was no moderating effect of other smokers living at home.ConclusionsFRESH behavioral counseling reduces child tobacco smoke exposure and promotes smoking quit rates in a highly distressed and vulnerable population.Trial RegistrationThis study is registered at www.clinicaltrials.gov NCT02117947.Copyright © 2015 American Journal of Preventive Medicine.
