Introduction
Preterm low-birth-weight infants should generally begin iron supplementation between the 4th and 8th week of life. Preterm infants refer to newborns born between 28 and 37 weeks of gestational age. These infants usually have low body weight and insufficient iron stores because iron transfer from mother to fetus primarily occurs during the late stages of pregnancy. Due to inadequate prenatal iron storage, most preterm infants require iron supplementation.
Preterm infants with low birth weight should generally start iron supplementation between 4 to 8 weeks of age, but the specific timing should be determined according to the infant's health condition under the guidance of a healthcare professional.
Preterm infants are newborns born between 28 and 37 weeks of gestational age. These infants typically have low body weight and insufficient iron stores because iron is primarily transferred from the mother to the fetus during the late stages of pregnancy. Since preterm infants are born earlier, they miss this critical period of iron transfer, resulting in inadequate iron reserves. Therefore, most preterm infants require iron supplementation. Iron supplementation usually begins around 4 to 8 weeks after birth and continues until approximately one year of age. If an infant’s iron levels are not severely low and additional iron is provided through formula feeding, the duration of supplementation may be adjusted accordingly.
Due to their special needs, preterm infants should be fed scientifically under medical supervision. Close monitoring of the infant's vital signs is recommended, along with proper care practices. Maintain a clean, hygienic, and temperature-appropriate living environment, and actively take measures to prevent illness.
