How is a neonate classified as appropriate for gestational age (AGA) based on weight percentiles?

A neonate is classified as appropriate for gestational age (AGA) when their weight falls between the 10th and 90th percentiles. This classification indicates that the neonate's growth and development align with the expected growth patterns for their gestational age, suggesting that the infant is neither underweight nor overweight compared to their peers born at the same gestational age.

This classification is important in assessing the neonate's health and development. Weight percentiles are determined using population data that reflects the distribution of birth weights across different gestational ages, allowing healthcare providers to identify those who may require further assessment or intervention based on their growth metrics. Those in the AGA category typically have better health outcomes compared to those who fall into the underweight or overweight categories. Understanding and identifying AGA is essential for proper monitoring and promoting optimal health during the neonatal period.
