Abstract：【Objective】To study the effects of breastfeeding on the growth and development, nutritional status, immune function and serum trace element levels of neonates. 【Methods】A total of 168 cases of pregnant women who gave birth in our hospital from January 2019 to December 2020 were included in this study. According to the feeding method, the newborns were divided into the formula-feeding group and breast-feeding group. The two groups were followed up for 6 months. The levels of various trace elements in the serum of the newborns were compared; The growth and development, immune function and nutritional status of the newborns in the two groups were analyzed; And the incidence of diseases in the two newborns groups within 6 months after birth was conducted statistically. 【Results】The serum trace elements of Copper, Zinc, Magnesium and Iron in the breast-feeding group were higher than those in the formula-feeding group (P<0.05). At birth, there were no statistically significant differences in growth and development indicators, immune function indicators and nutritional status indicators between the two groups (P>0.05). After 6 months of birth, the height and weight of newborns in both groups increased compared to those at birth (P<0.05). However, there was no difference in body weight and height between the two groups (P>0.05). The levels of IgA and IgM of newborns in the two groups at 6 months after birth were all higher than those at birth (P<0.05), while IgG of newborns in the formula-feeding group was lower than that after birth (P<0.05). At 6 months after birth, levels of IgA, IgM and IgG in the breast-feeding group were all higher than those in the formula-feeding group (P<0.05). Levels of CD3+, CD4+, and CD4+/CD8+ in both groups were all higher than those at birth (P<0.05), and the breast-feeding group was higher than that of the formula-feeding group (P<0.05). The Kaup index of the two groups was higher than that at birth, while the LAZ score and WAZ score were lower than those at birth (P<0.05). The Kaup index, LAZ score and WAZ score of the breast-feeding group were higher than those of the formula-feeding group (P<0.05). There was no difference in the incidence of disease within 6 months between the two groups (P>0.05). 【Conclusion】Breastfeeding helps to better maintain newborn serum trace element levels, enhance newborn immune function and improve nutritional status.
