Brief Summary

Introduction: Preterm infants with a birth weight less than 1500 grams have special nutritional needs in comparison to full-term neonates. During their stay in the neonatal intensive care unit an increased supply with energy, protein and electrolytes is necessary to establish adequate growth. After discharge from the hospital special breast milk supplements or post discharge formulas are available to cover the special nutrient requirements. Complementary feeding in preterm infants is an unexplored field so far and nutritional concepts for the first year of life are not available. Data concerning the optimal time for starting solid foods are missing as well as information concerning the ideal composition of complementary food. In this context it is essential to meet the special nutritional needs of "Ex-Preemies" on the one hand and avoid overfeeding and later obesity on the other hand. So far it remains unclear, what the "safe" time point for introduction of solid food to premature infants is and whether this time point influences growth, body composition, neurodevelopmental outcome or the incidence of atopic disease.

Detailed Description

Aim: In a prospective, randomized, two arm intervention study- the PIES project- we aim to investigate the impact of different time points of introduction of complementary food on growth, body composition, atopic disease and neurodevelopmental outcome in preterm infant with a birth weight <1500 grams. Furthermore, we want to investigate whether a certain standardized feeding protocol meets the nutritional needs of premature infants, and obtain data on safety and efficacy in this context. Methods: At term infants are stratified according to breastfed or formula fed and randomized in one of the following groups: an EARLY complementary feeding group (introduction of complementary food between the 10th and 12th week of life corrected for term, n=76) and LATE complementary feeding group (introduction of complementary food between the 16th and 18th week of life corrected for term, n=76). The infants will be fed with standardized complementary food in addition to formula or breastfeeding until they are one year corrected for prematurity. In an age dependent step up concept, food boxes are delivered to the parents: five types of standardized food boxes with manifold complementary food according to the infants' age and the ability to tolerate small pieces are available for each child during the study. The standardized complementary feeding regimen allows calculating exact intake of nutrients and therefore will provide information concerning primary and secondary outcome. The follow up phase will last until 5 years of age. Within regular visits anthropometric data (height, head circumference, weight, BMI and z-scores ) and body composition via the PeaPod® system will be gathered. Data on atopy will be assessed by clinical scoring system SCORAD (SCORing Atopic Dermatitis) and the laboratory parameters Fx5(Fx5 test uses six food allergens: wheat, egg, cow's milk, soya, peanut and fish) and IgE (immuneglobulineE). Neurodevelopmental outcome will be assessed at the age of one and two years corrected for term by the Bayley Scales and the K-ABC (Kaufman Assessment Battery for Children). The nutritional concept will be monitored concerning short term safety and efficacy (bone metabolism, iron status, protein- and lipid status) as well as regarding long term outcome (diabetes and obesity markers IGF-1 (Insulin-like growth factor-1, adiponectin and leptin).

With the PIES project we intend to close a gap of knowledge in feeding the premature infant during the first year of life and to understand the impact of complementary feeding on growth, atopy, neurodevelopmental outcome and later obesity.
