OBJECTIVE: Exclusive breastfeeding is recommended for the first 6 months of life, but there are racial/ethnic disparities in meeting this recommendation. METHODS: 2017-2020 North Dakota Pregnancy Risk Assessment Monitoring System (weighted N = 11,754) data were used to examine racial/ethnic differences in the association between self-reported breastfeeding barriers and breastfeeding duration. Breastfeeding duration was self-reported breastfeeding at 2 and 4 months, and number of weeks until breastfeeding cessation. Self-reported breastfeeding barriers were yes/no responses to 13 barriers (e.g., "difficulty latching," "household duties"). Logistic regression estimated odds ratios and 95% confidence intervals to determine if barriers accounted for breastfeeding disparities by race/ethnicity. Cox proportional hazard models estimated hazard ratios for stopping breastfeeding for American Indian and other race/ethnicity individuals, compared to White individuals. Models were adjusted for birthing parents' demographic and medical factors. RESULTS: Logistic regression results suggest American Indian birthing parents had similar odds for breastfeeding duration (2-month duration: OR 0.94 (95%CI 0.50, 1.77)
4-month duration: OR 1.24 (95%CI 0.43, 3.62)) compared to White birthing parents, after accounting for breastfeeding barriers. Cox proportional hazard models suggest American Indian birthing parents had a lower hazard of stopping breastfeeding (HR 0.76 (95%CI 0.57, 0.99)) than White parents, after accounting for breastfeeding barriers. CONCLUSIONS: Accounting for breastfeeding barriers eliminated observed disparities in breastfeeding outcomes between American Indian and White birthing parents. Targeted and culturally safe efforts to reduce barriers to breastfeeding are warranted to reduce racial/ethnic disparities in breastfeeding.
