What are the protein goals for growth in preterm and term infants?

The protein goals for growth in preterm and term infants are based on their distinct nutritional needs, considering their rates of growth and developmental stages. The correct range of 3.5-4 g/kg for preterm infants is based on the higher demands of these infants, who require more protein to support rapid growth and organ development. Due to their lower gestational age, they have less body mass and immature organ systems, which necessitates a higher protein intake for optimal growth.

For term infants, the protein requirement of 1.5-3 g/kg is sufficient, as they generally have already completed most of their organ maturation and are growing at a steadier rate compared to preterm infants. This lower range accounts for the differing growth rates and is aligned with recommendations that address the normal physiological needs of full-term infants.

Setting these specific protein goals for both preterm and term infants is crucial in pediatric care to ensure that both groups receive adequate nutrition for healthy growth and development.
