Abstract

Introduction: Racial disparities exist in maternal and neonatal care including breastfeeding (BF). The purpose of this study is to assess factors associated with BF success by race with a specific focus on pre-birth BF plan and time duration from birth until initiation of skin-to-skin contact and from birth to the first feed or breastfeed.

Methods: A database query of our electronic medical records was performed for all patients who had a vaginal delivery that met our study criteria. Demographic information, pre-delivery feeding plan (exclusive BF, exclusive formula, or mixed), time to first feed and first breastfeed, and time to skin-to-skin were compared among different postpartum feeding practices (exclusive BF, exclusive formula, mixed), and compared across race/ethnic groups using ANOVA, Chi-square, and Fisher's exact statistical tests as appropriate. Logistic regression was used to investigate the independent effect of each variable on exclusive BF.

Results: The study analyzed 12,578 deliveries. There was a significant difference in intended feeding plans among the different racial groups. Approximately 61% of Black patients intended to exclusively BF as compared to 79% of the other groups. Overall, 3994 (32%) patients breastfed exclusively, 872 (7%) exclusively used formula, and 7712 (61%) used a mix of breast and formula. White patients were most likely to exclusively BF (35%) and Black patients were least likely (21%), p < 0.001. Our model found that self-identified race and pre-delivery feeding plan were the strongest predictors of exclusive BF.

Conclusions: The main findings of this study are that self-identified race and intention to BF are the strongest predictors of exclusive BF. Black patients intend to BF at a significantly lower rate than other racial groups, for reasons not determined by this study, and this affects feeding practice. Our findings are notable because prehospital intention to BF can be modified by outreach, education, and changes to in-hospital practices.
