What is the adequate intake for a preterm infant less than 34 weeks?

For preterm infants less than 34 weeks gestational age, the recommended adequate intake is typically around 160 mL/kg/day of fortified human milk. This volume is essential to ensure that these infants receive sufficient nutrients to support their rapid growth and development, which is crucial due to their increased nutritional needs compared to full-term infants. Fortified human milk is specially designed to provide the additional calories, proteins, and minerals that preterm infants require to achieve optimal growth and to minimize the risks of complications associated with prematurity.

The importance of adequate intake in this population cannot be overstated, as preterm infants are at risk for growth failure and other nutritional deficiencies. Ensuring they receive the appropriate volume of fortified milk helps in addressing these risks and supports their development in the neonatal period.

The other options suggest varying volumes or formulas that may not meet the specific needs of infants under 34 weeks gestation. For instance, the higher volume suggestions could lead to excessive intake or complications, while lower volumes do not provide sufficient nutrition for the demanding growth and developmental needs of preterm infants at this stage. Thus, the intake of 160 mL/kg/day of fortified human milk is recognized as adequate and beneficial for promoting health outcomes in this vulnerable population.
