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.
