What percentile defines a large-for-gestational-age (LGA) neonate?

A large-for-gestational-age (LGA) neonate is defined as one that falls at or above the 90th percentile for weight for a given gestational age. This means that an LGA infant is heavier than 90% of infants of the same gestational age. This classification is significant as it may indicate potential complications for both the baby and the mother, such as increased risk of delivery complications. Identifying LGA status is important for appropriate neonatal care and monitoring. Thus, the correct definition of LGA aligns with the 90th percentile mark.
