Abstract: Objective To investigate the effect of complementary formula on feeding patterns at 6 months of age, in order to provide scientific reference for standardizing the management of adding formula during hospitalization. Methods A prospective cohort study was conducted. Methods A prospective cohort study was conducted.The demographic data of 372 mothers and infants in Shanghai First Maternity and Infant Hospital from January to March 2020 were collected as the baseline, and formula addition was as the exposure factor during hospitalization.The feeding patterns of infants at discharge, 42 days postpartum, 3 months of age and 6 months of age were used as outcome indicators.Meanwhile, the formula complementary during hospitalization was considered as an independent variable, and the breastfeeding outcome of 6 months postpartum infants was used as a dependent variable.Logistic regression was used to analyze the association between formula complementary during hospitalization and postpartum feeding patterns. Results A total of 131 infants had formula added during hospitalization.Logistic regression analysis showed that the formula complementary during hospitalization increased the risk factor for exclusive breastfeeding failure at 6 months postpartum(OR=2.110, 95%CI:1.194-3.729,P＜0.05). Conclusions The situation of formula addition during hospitalization is not optimistic, which will affect the exclusive breastfeeding rate of 6-month-old infants after delivery.Obstetric medical staff should attach great importance to it, strictly implement the indications of milk addition, and scientifically supervise and manage the formula complementary during hospitalization.

摘要： 目的 调查产妇分娩住院期间为新生儿添加配方奶对其产后6个月喂养方式的影响,为规范婴儿住院期间配方奶的添加管理提供科学依据。 方法 本次研究为前瞻性队列研究,以上海市某妇产科专科医院常规体检的产妇为基线人群,婴儿在院期间添加配方奶作为暴露因素,调查2020年1—3月在院期间372名母婴的人口学资料及配方奶添加情况,以出院时、产后42天、3月龄及6月龄婴儿的喂养方式为结局指标。同时,将住院期间添加配方奶作为自变量,产后6月婴儿母乳喂养结局作为因变量,通过Logistic回归分析调查住院期间配方奶添加与产后喂养方式的关联。 结果 131名婴儿在住院期间添加过配方奶,Logistic回归分析结果显示,在控制混杂因素后住院期间配方奶添加增加了产后6月纯母乳喂养失败的风险(OR=2.110,95%CI:1.194~3.729,P＜0.05)。 结论 住院期间配方奶添加情况不乐观,将影响产后6月龄婴儿的纯母乳喂养率,产科医务工作者应予以高度重视,严格执行加奶指征,对住院期间配方奶添加实施科学监督和管理。
