Impact of smoking status and repeat cesarean section on breastfeeding duration
methods: 2004-2011 data from the Pregnancy Assessment Monitoring System (PRAMS) was analyzed. Breastfeeding duration (outcome) was based on the survey item, “How many weeks or months did you breastfeed or pump milk to feed your baby?”. Repeat C-Section (exposure) was based on the survey item, “How was your new baby delivered, vaginally or by Cesarean delivery?” and if they had a previous C-Section. Multiple logistic regression was used to determine the effect of repeat C-Section on breastfeeding duration.
results: Women who smoke and have a repeat C-Section had 6-times higher odds of (AOR=6.15, 95% CI= 1.98-19.14) breastfeeding for 8 weeks or less and a 4-times higher odds of never breastfeeding (AOR=4.01, 95% CI= 1.55-10.41) compared to women who give birth by VBAC. Among non-smokers, no association was observed for breastfeeding 8 weeks or less (AOR=1.35, 95% CI=0.92-1.99) and the association for never breastfeeding diminished (AOR=1.97, 95% CI=1.29-3.02).
conclusions: The results suggest that repeat C-Section negatively affects breastfeeding duration. In addition, smoking women who had repeat C-Section were more likely to never breastfeed or breastfeed for a shorter amount of time. Interventions are needed for mothers who smoke and undergo repeat C-Section.
