Abstract:

Objective　To analyze the relationships between different feeding manners and iron deficiency anemia in 6-month-old infants. Methods　A total of 623 6-month-old infants who accepted health care and blood routine test in Guangdong Women's and Children's Hospital from December 2022 to February 2023 were selected, including 364 boys with a birth weight of (3.22±0.33) kg and 259 girls with a birth weight of (3.11±0.33) kg. They were divided by feeding manners into a breast-feeding group (201 cases, exclusive breast-feeding from birth to 6 months old), an artificial feeding group (289 cases, exclusive infant formula feeding after birth), and a mixed feeding group (133 cases, partial breast-feeding + infant formula feeding after birth). The anemia related indexes such as hemoglobin in the blood routine of the three groups were sorted out and the anemia conditions in the three groups were analyzed. χ² test was used. Results　The incidence of iron deficiency anemia in the 6-month-old infants was 22.3% (139/623), all of which were mild anemia. The incidence of iron deficiency anemia in the breast-feeding group [30.8% (62/201)] was higher than that in the artificial feeding group [15.9% (46/289)] and the mixed feeding group [23.3% (31/133)], with a statistically significant difference (χ²=15.340, P<0.001). Conclusions　Breast feeding infants have a higher prevalence of iron deficiency anemia, but mostly are mild anemia. Breast milk is still the most ideal natural food for infants, but iron-rich complementary food should be added promptly and reasonably, in order to prevent iron deficiency anemia.
