Analysis of the duration of exclusive breastfeeding in premature infants and its influencing factors

PurposeThe purpose of this study was to investigate the duration of breastfeeding among preterm infants within the first 12 months after birth and analyzed factors influencing the duration of exclusive breastfeeding.Design and methodsIn this retrospective study, premature infants who were hospitalized in the Neonatal Intensive Care Unit (NICU) premature delivery area of a third-class maternal and child health hospital in Changsha City, Hunan Province, China from October 2020 to January 2021 were selected as the participants for this study. Relevant data of these infants during their hospitalization was obtained from the hospital information system, while the rate of exclusive breastfeeding among preterm infants at a corrected age of 12 months was tracked through telephone follow-up. Univariate analysis of the effects of breastfeeding duration in preterm infants was conducted based on Mann–Whitney U test and Kruskal–Wallis H test. Multiple linear regression was then applied to determine the factors influencing the duration of exclusive breastfeeding in preterm infants.ResultsThe median and interquartile range of breastfeeding duration for preterm infants in this study was 4.00 (1.00, 6.00) months. Multiple linear regression analysis showed that the duration of exclusive breastfeeding was affected by several factors including how much other family members support breastfeeding, whether the mother returns to work after maternal leave, and whether the infant is a twin (P < 0.05).ConclusionThe duration of exclusive breastfeeding among preterm infants needs to be improved by strengthening health education regarding the benefits of breastfeeding for preterm infants. Medical staff should provide guidance, encourage continuous nursing after discharge, and work with the community to implement targeted intervention measures with the goal of increasing the duration of exclusive breastfeeding among premature infants.Implications to practiceBecause breastfeeding is vitally important for premature infants, we should encourage longer breastfeeding duration for premature infants by increasing family support, removing barriers to workplace breastfeeding, enhancing people's confidence in breastfeeding and providing support to mothers with twins. Hopefully, these measure can promote breastfeeding for premature infants.
