Improved breastfeeding duration with Baby Friendly Hospital Initiative implementation in a diverse and underserved population.

Background: Few studies have evaluated the impact of Baby Friendly Hospital Initiative (BFHI) implementation on underserved populations in the United States. We undertook this study in New Mexico, a large southwestern state with a diverse population and limited health care access. Methods: A quasi‐experimental, retrospective cohort design was used to compare short‐term breastfeeding duration between a pre‐BFHI and a post‐BFHI cohort. Among the post‐BFHI cohort, logistic regression models were fitted to predict short‐term breastfeeding duration from both individual and cumulative exposure to inpatient maternity care practices (Steps 4 to 9). Results: Implementation of the BFHI and cumulative exposure to the Ten Steps increased short‐term duration of any breastfeeding and exclusive breastfeeding at 2‐6 weeks postpartum. Exposure to all six of the inpatient Ten Steps increased the odds of any breastfeeding by 34 times and exclusive breastfeeding by 24 times. Exposure to Step 9 ("Give no pacifiers or artificial nipples") uniquely increased the likelihood of any breastfeeding at 2‐6 weeks postpartum by 5.7 times, whereas Step 6 ("Give infants no food or drink other than breastmilk") increased the rate of exclusive breastfeeding by 4.4 times at 2‐6 weeks postpartum. Conclusion: These findings demonstrate that the Baby Friendly Hospital Initiative can have a positive impact on breastfeeding among underserved populations. [ABSTRACT FROM AUTHOR]
