Abstract

Background and Objective: Maternal postpartum smoking increases the risk for poor infant health outcomes, while exclusive breastfeeding has been shown to support infant health. Limited population-based research has been published on the interaction between maternal smoking and exclusive breastfeeding. The objective of this study was to examine factors modifying the association between maternal postpartum smoking and exclusive breastfeeding among women in the United States. Methods: Secondary data analysis was conducted using the 2009-2011 Pregnancy Risk Assessment Monitoring System. Stratified analyses were used to examine the associations between maternal postpartum smoking and exclusive breastfeeding by sociodemographic factors. Results: The postpartum smoking rate was 17.1%. The relationship between postpartum smoking and exclusive breastfeeding at 12 weeks varied by maternal education level, race/ethnicity, Medicaid use, and pregestational or gestational diabetes. The magnitude of reduction in the odds of exclusive breastfeeding at 12 weeks postpartum among the women who smoked in the postpartum period ranges from odds ratio (95% confidence interval) 0.52 (0.37-0.74) for non-Hispanic blacks to 0.31 (0.22-0.43) for women who had <12 years of education. Conclusions: Women who smoked in the postpartum period, who also suffered from socioeconomic disadvantages, had a higher likelihood of not continuing exclusive breastfeeding. Identification of women at high risk for not exclusively breastfeeding is important for targeting populations in need of appropriate and timely support for prenatal and postpartum smoking cessation and breastfeeding promotion.
