Abstract
OBJECTIVES: Exclusive breastfeeding is the ideal source of nutrition for the first 6 months of life. Although skin-to-skin contact (SSC) has been shown to be associated with greater rates of exclusive breastfeeding, the results are heterogeneous. SSC involves placing a naked infant on its mother's bare chest immediately after birth. We examined the association between SSC immediately after birth and exclusive breastfeeding at 4 months. METHODS: A retrospective cohort of healthy, term, singleton infants who were liveborn from 2008 to 2019 was constructed from the Nova Scotia Atlee Perinatal Database. Our main outcome was exclusive breastfeeding at 4 months, available for a subset of the cohort through linkage to a primary care database (n=256). Our secondary outcome was exclusive breastfeeding at hospital discharge, available for the broader cohort (n=56,459). Odds ratios (OR) for the association between SSC and exclusive breastfeeding at 4 months were estimated from logistic regression models. RESULTS: The odds of breastfeeding exclusively at 4 months were 4.14 (95% confidence interval (CI) 1.89-9.25) times greater among those who had SSC than among those who did not. The odds of breastfeeding exclusively at hospital discharge were 3.81 (95% CI 3.64-3.99) times greater among those who had SSC than among those who did not. The association between SSC and exclusive breastfeeding at hospital discharge was heterogeneous by birth year (OR 4.35, CI 4.07-4.65 in 2008-2011; OR 2.81, CI 2.57-3.07 in 2012-2015; OR 1.89, CI 1.63-2.10 in 2016-2019). CONCLUSION: Skin-to-skin contact appears to be associated with greater odds of exclusive breastfeeding at discharge and 4 months postpartum. Early SSC should continue to be supported for breastfeeding promotion.
