Pediatric Office Delivery of Smoking Cessation Assistance for Breast-Feeding Mothers.

introductionNational and international organizations have done an excellent job of advocating and promoting breast feeding for all mothers. This study assessed to what extent an intervention increased delivery of cessation assistance to breast-feeding mothers who smoke.

methodsData were collected between April and October 2015 in five US states as part of a cluster randomized controlled trial in 10 pediatric practices. Practices were randomized to the Clinical Effort Against Secondhand Smoke Exposure (CEASE) intervention or usual care control arms. Mothers were asked about their smoking status and breast-feeding history during a screening interview upon exiting the practice and eligible mothers who agreed to participate in an enrollment interview were asked if they received smoking cessation assistance during their child's visit. Mothers with a child 1 year old and younger were included in the analyses.

resultsCurrent breast feeding was associated with a reduced likelihood of current smoking (adjusted odds ratio [aOR] = 0.38, 95% confidence interval [95% CI] = 0.25 to 0.57) and a greater likelihood of quitting smoking (aOR = 2.33, 95% CI = 1.29 to 4.21) after controlling for known confounders. Mothers who concurrently smoked and breast-fed were more likely to be asked about smoking (66.7% vs. 28.6%, p = .01), advised to quit (61.1% vs. 21.4%, p < .01), prescribed nicotine replacement therapy (50.0% vs. 0%, p < .001), and enrolled into the quitline (27.8% vs. 0%, p < .01) at CEASE practices compared to control practices.

conclusionBreast-feeding mothers were less likely to be current smokers and more likely to have recently quit smoking. Among mothers who continue to smoke and breast feed, the CEASE intervention enhances delivery of smoking cessation assistance. IMPLICATIONS: Breast feeding and eliminating infants' exposure to tobacco smoke are important protective factors for serious pediatric health risks including sudden infant death. This study shows that breast feeding was positively associated with desirable tobacco control outcomes, specifically that breast feeding was associated with a lower likelihood of smoking among ever smokers and a greater likelihood of recently quitting smoking. This is also the first study to look specifically at delivery of smoking cessation assistance to breast-feeding mothers seen at pediatric offices and demonstrates the effectiveness of delivering evidence-based smoking cessation assistance to them in this context.
