ICD-11

Infants whose weight is appropriate for their gestational ages are termed appropriate for gestational age (AGA). Infants that are heavier than expected are large for gestational age (LGA). Conversely, those smaller than expected are considered small for gestational age (SGA).

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.

When both birth weight and gestational age are available, priority of assignment should be given to birth weight.

Less than 28 completed weeks (less than 196 completed days) of gestation.

When both birth weight and gestational age are available, priority of assignment should be given to birth weight.

Extreme prematurity of newborn, gestational age less than 22 weeks, 0 days

When both birth weight and gestational age are available, priority of assignment should be given to birth weight.
