Discussion on normal development patterns of breastfed infants in the first year

Abstract

 A total of 369 children born from January 1990 to December 1992 in Fenglin Street were selected, including 175 males and 194 females. According to different feeding methods, they were divided into exclusive breastfeeding group (146 people) and artificial feeding group (223 People). Observe the weight, length, head circumference, chest circumference and mid-upper arm circumference of children from 1 to 6, 9 and 12 months old, calculate the monthly, 6 to 9 and 9 to 12 month increases in weight and length, and compare the two The incidence of anemia, rickets, respiratory tract infection and diarrhea in the first and second half of the year in the group. Taking women as an example, the weight of the artificial group exceeded that of the breast milk group from 4 months onwards, and reached significance at 9 and 12 months. The body length exceeded that of the breast milk group from 3 months onwards. In the breast milk group, the difference is significant. The chest circumference and arm circumference exceed each other at 5 and 12 months respectively. Except for the first month, the weight gain of the artificial group is slightly greater than that of the breast milk group, and the difference is significant from 6 months onwards. .The length gain of the artificial group in the first half of the year was greater than that of the breast milk group, and it was significant at 2 and 3 months. The growth of male children was similar to that of women. There was no difference in the incidence of anemia between the two groups. However, rickets and respiratory tract disease in the first half of the year The infection rate in the artificial group was significantly higher than that in the breast milk group. There was no difference in the number of diarrhea throughout the year and respiratory infections in the second half of the year between the two groups. It is suggested that breastfeeding should be encouraged, especially in the first few months after birth. Complementary foods should be added in time starting from 4 months old. As the amount of breast milk decreases, the addition of dairy products cannot be ignored.
