Background: In recent years, China has actively promoted the publicity and promotion of breastfeeding, because breastfeeding is conducive to the healthy growth of babies and conducive to the recovery of maternal health. Behavioral nursing theory holds that individual behavior change is a complex and continuous process, and personalized care is given at different stages of individual behavior change to promote individual behavior change.

Objective: To explore the impact of behavioral nursing intervention on the breastfeeding maintenance rate of hospitalized newborns.

Design: This was a prospective cohort study based on the description provided.

Setting: This study was conducted in the Department of Pediatrics, Shanghai Six People's Hospital/Shanghai Six People's Hospital Affiliated with Shanghai Jiaotong University School of Medicine, because the author worked in the hospital.

Participants: A total of 120 cases of parturients in our hospital from January 2021 to December 2022 were chosen and separated into a control group and an observation group through the random number table method. Inclusion criteria: Parturients were full-term single pregnancies, examined in our hospital, and there were no abnormalities in prenatal examination. Exclusion criteria: Parturients with a history of mental illness, accompanied by hepatitis B, three Yang, acquired immune deficiency syndrome and other infectious diseases, and combined with visual and hearing disorders.

Interventions: The control group adopted routine breastfeeding nursing intervention, including training in the prenatal maternity school, instruction in breastfeeding methods during hospital delivery and follow-up after discharge. The observation group adopted behavioral nursing intervention, the corresponding health guidance and nursing methods were formulated and implemented in the second trimester, the third trimester, the hospitalization period of childbirth, and the discharge, and at each stage.

Primary Outcome Measures: (1) Degree of knowledge about breastfeeding, (2) Efficiency of breastfeeding, (3) Rate of exclusive breastfeeding, (4) Nutritional index, (5) Cognitive ability of newborns, (6) Satisfaction of family members with nursing.

Results: After the intervention, the score of feeding knowledge in the observation group was elevated relative to the control group (P < .05). The self-efficacy scores and rates of exclusive breastfeeding in the observation group at 1, 6 weeks, and 6 months after delivery were higher relative to the control group (P < .05). After the intervention, the levels of albumin, albumin, and transferrin in the observation group were higher relative to the control group (P < .05). After the intervention, the scores of the mental development index and psychomotor development index in the observation group were elevated relative to the control group (P < .05).

Conclusion: Behavioral nursing can effectively improve the effectiveness of breastfeeding and facilitate the health and growth of mothers and newborns, aligning with the broader goals of promoting breastfeeding in healthcare settings.
