Overview
Anemia of prematurity is a common problem in NICU. It usually affects preterm and low birth weight infants born before 32-weeks of gestation. It affects male and female infants equally with no racial predilection.
Incidence
- Anemia of prematurity is a common problem in neonatal intensive care units (NICU)
- Each week, in the United States, 10,000 new cases of premature births are reported[1]
- Extremely low birth weight (ELBW) infants constitute about 6% of the premature births
- Approximately, 80-90% of ELBW infants require at least one blood transfusion due to anemia of prematurity
Age
- Anemia of prematurity is commonly seen in premature infants born before 32-weeks of gestation[2]
- The risk of anemia of prematurity is inversely proportional to weeks of gestation and weight at the time of birth
- Nearly, 50% of ELBW infants and infants born before 29 weeks of gestation require at least one blood transfusion during first two weeks of life. More than 80% of such infants receive additional blood transfusion before getting discharge from hospital[3]
Gender
The prevalence and incidence of anemia of prematurity do not vary by gender
Race
There is no racial predilection for anemia of prematurity
