Objective: Moderately preterm (MP) (32–33 weeks) and late preterm (LP) (34–36 weeks) infants have higher risks of mortality and growth and developmental problems. We, herein present a new concept of nutritional assessment, total energy intake (TEI), which is the sum total of kilocalories administered in all nutrient forms.
Methods: Fifty-two preterm infants were classified as MP (n?=?12), LP/appropriate for gestational age (LP/AGA) (n?=?33), or LP/small for gestational age (LP/SGA) (n?=?7). All groups received nutrient therapy by the same protocol. The sum of the daily energy intake at 14 and 28 days after birth was determined.
Results: TEI was 2822.1?±?162.1?kcal/kg/28 days in the MP group, 3187.2?±?265.0?kcal/kg/28 days in the LP/AGA group and 3424.6?±?210.4?kcal/kg/28 days in the LP/SGA group. In all groups, TEI for 28 days was significantly correlated with body weight gain (r?=?0.465, p?=?0.006). TEI for 14 days after birth was inversely correlated with the body weight loss rate after birth (r?=?-0.491, p?=?0.0002).
Conclusion: TEI was well correlated with anthropometric changes after birth. TEI may be used to effectively assess preterm infants’ nutritional needs.
