A Geospatial Analysis of the Impact of the Baby-Friendly Hospital Initiative on Breastfeeding Initiation in North Carolina.

Background:: Significant disparities in breastfeeding support and practice exist in North Carolina. The Baby-Friendly Hospital Initiative is a worldwide intervention that encourages birth facilities to adopt specific practices in support of breastfeeding.

Research Aim:: This study aimed to evaluate the impact of the Baby-Friendly Hospital Initiative on breastfeeding initiation in North Carolina, with special attention to rural areas.

Methods:: To better understand disparities in breastfeeding initiation across North Carolina, we conducted a secondary analysis of birth certificate data from 2011 to 2014. Univariate and multivariate logistic regression models were used to estimate the association between breastfeeding initiation and (a) birth at a Baby-Friendly hospital and (b) maternal residence in a county with a Baby-Friendly hospital. Model residuals were aggregated by county and analyzed for spatial autocorrelation.

Results:: Birth at a Baby-Friendly hospital was associated with increased odds of breastfeeding initiation, adjusted odds ratio = 1.7, 95% confidence interval [1.65, 1.89]. Model residuals showed significant clustering by county, with some rural areas' rates systematically overestimated. Whereas presence of a Baby-Friendly hospital in a mother's community of residence was not associated with increased initiation, birth at a Baby-Friendly hospital was associated with smaller disparities in initiation between rural and urban births.

Conclusion:: Birth at a Baby-Friendly hospital is associated with improved breastfeeding initiation and reduced disparities in initiation between rural and urban counties in North Carolina.
