Definition
Infants whose weight is appropriate for their gestational ages are termed appropriate for gestational age (AGA). Infants that are heavier then expected are large for gestational age (LGA). Conversely, those smaller then expected are considered small for gestational age (SGA). Factors to consider in addition to gestational age when determining the likelihood of favorable outcome with intensive care include, female sex, antenatal corticosteroids and singleton birth. Infants born at<28 weeks have a higher incidence of poor neurodevelopmental outcome, hearing loss, chronic lung disease and retinopathy of prematurity.
Coding note
When both birth weight and gestational age are available, priority of assignment should be given to birth weight.
