['Several studies have shown that rooming-in can have a positive impact on lactation success. The objective of this study was to assess if the establishment of rooming-in in a community hospital has an impact on breastfeeding success.', 'Participants included volunteer women who delivered babies at a community hospital. The participants answered a survey.', 'Sixty females were included. The mean age was 23 years (18-38) and the mean gestational age 38 weeks (34-41). Breastfeeding in the hospital was reported by 54% with 6% doing it exclusively. Rooming-in was practiced by 70%. Rooming-in was associated to breastfeeding (OR 5.0, 95% CI 1.5-16.9, p = 0.0069). Thirty-percent of the babies in rooming-in started breastfeeding during the first 6 hours after delivery as compared to none of those not roomed-in.'] Does rooming-in improve breastfeeding initiation rates in a community hospital in Puerto Rico?
