Growth of Preterm Infants Fed a Infant Milk Formula Containing High Versus Low Amounts of Beta-palmitate

Официальное название

A Randomized, Multicenter, Controlled Clinical Trial to Assess Weight Gain of Preterm Infants Fed a New Infant Milk Formula Containing High Amounts of Beta-palmitate Versus a Standard Infant Milk Formula Containing Low Amounts of Beta-palmitate

Обзор

The aim of this study is to assess weight gain of preterm infants (gestational age lower than 32 weeks) fed infant milk formula with about 60% beta-palmitate (EX\_IMF) vs infant milk formula with similar macronutrient, mineral and fatty acid composition but lower amounts of beta-palmitate (ST\_IMF). Own mother milk (OMM) fed infants will serve as reference group.

Подробное описание

A large number of low birth weight infants during their hospital stay experience poor growth and this has been linked to reduced neurodevelopment scores.

Several enriched infant milk formulas are available for preterm infants who cannot be fed human milk. The use of infant milk formulas (IMF) enriched with triglycerides similar to human milk lipids have shown to be associated with better fatty acid and mineral intestinal absorption.

In this multicenter, randomized, controlled clinical trial, preterm infants (gestational age lower than 32 weeks), who can not be fed human milk, will be randomized to receive IMF with high or low amounts of beta-palmitate (about 60% vs 10%, respectively). A non-randomized own human milk-fed group will be included as a reference. Patients will be on the study diet as soon as possible after birth and till 36 weeks of gestation. Neurodevelopment follow-up will be performed at 24 months corrected age.
