Tobacco Use Cessation Among Quitline Callers Who Implemented Complete Home Smoking Bans During the Quitting Process

Introduction The implementation of a home smoking ban (HSB) is associatedwith tobacco use cessation. We identified which quitline callerswere most likely to report 30-day cessation among those who implementedcomplete HSBs after enrollment.MethodsOur sample consisted of callers to the Arizona Smokers’ Helplinewho enrolled from January 1, 2011, through July 26, 2015, andwho reported no HSB at enrollment and a complete HSB by 7-month follow-up. We used logistic regression to estimate associationsbetween no use of tobacco in the previous 30 days (30-dayquit) at 7-month follow-up and demographic characteristics, healthconditions, tobacco use, and cessation strategies.ResultsAt 7-month follow-up, 65.4% of 399 callers who implemented acomplete HSB reported 30-day quit. Lower odds of tobacco usecessation were associated with having a chronic health condition(odds ratio [OR], 0.31; 95% confidence interval [CI], 0.18–0.56)and living with other smokers (OR, 0.46; 95% CI, 0.29–0.73).Higher odds of tobacco cessation were associated with completing5 or more telephone coaching sessions (OR, 2.48; 95% CI,1.54–3.98) and having confidence to quit (OR, 2.05; 95% CI, 1.05–3.99). However, confidence to quit was not significant in thesensitivity analysis.ConclusionImplementing an HSB after enrolling in quitline services increasesthe likelihood of cessation among some tobacco users. Individualswith complete HSBs were more likely to quit if they didnot have a chronic health condition, did not live with anothersmoker, and were actively engaged in coaching services.
