Abstract: Objective: To explore the effect of nursing intervention based on planned behavior theory on the breastfeeding in late-preterm infants. Methods: A total of 92 late-preterm infants and their mother in the neonatal department in a hospital in Tianjin from March 2023 to October 2023 were conveniently selected as the research subjects. According to the date of their hospitalization, 46 infants and their mothers from the first four months were selected as the control group, and 46 infants and their mothers from the second four months were selected as the intervention group. The control group implemented the routine nursing, and the intervention group implemented the nursing intervention based on the theory of planned behavior, including the routine nursing. The breastfeeding self-efficacy, breastfeeding volume at the second week after birth, and the breastfeeding status in preterm infants between the two groups were compared. Results: After intervention, the breastfeeding self-efficacy scores of the mothers and breastfeeding volume at the second week after birth in the intervention group were significantly higher than those in the control group (P<0.05); the time of first breastfeeding, the proportion of medium and high breastfeeding rate during hospitalization, exclusive breastfeeding rate at discharge and 1 month after discharge were all significantly better than those in the control group (P<0.05). Conclusion: The nursing intervention based on the theory of planned behavior can effectively improve breastfeeding self-efficacy of mothers with late-preterm infants, and increase the rate of exclusive breastfeeding of late-preterm infants.
