Study summary

The aim of this study is to evaluate the effect of increasing amino acid and energy intake during parenteral and enteral nutrition with and without the stimulation of the infant's physical activity, on growth of extremely low birth weight infants .

Read the detailed description

Increasing protein and energy intake above the anabolic capacity of a given individual may result in increased lipogenesis and excessive fat deposition. Adults with reduced mobility or with neuromuscular conditions will develop excessive fat deposition if they receive normal to high protein and energy intakes. Excessive fat deposition have been demonstrated in preterm infants receiving high energy intakes. Given that physical activity in preterms is often reduced for the prematurity itself, the associated sickness and the numerous medications, the investigators speculate that physical stimulation may have a beneficial effect on protein accretion and on lean mass accretion. The investigators further hypothesize that today's recommended daily intakes of proteins and energy cannot be fully incorporated into lean body mass without a concomitant physical activity. In spite of the fact that this notion is well accepted in adult physiology and in the elderly, it has never been tested in preterm infants.

This factorial randomised controlled trial will evaluate the effect of increasing amino acid intake (by 1 g/kg/d) and energy intake (by 20 kcal/kg/d) during parenteral nutrition and also of increasing protein intake and energy intake by an extra 1 g/kg/d during enteral nutrition, with and without the stimulation of the infant's physical activity, on growth of extremely low birth weight infants. The investigators aim at demonstrating that increasing energy and protein intake above the standard of care intakes will result in better growth only in association with adequate physical activity, in particular in relation to body composition and lean mass accretion.

    Physical activity stimulation consists in flexion/extension of the 4 limbs and other motion exercises of the shoulder girdle and of the hips. This stimulation will take place before the feed for a mean of 30 times a week (minimum 24- maximum 36 times a week, 10 minutes each time) and will start within the 10th day of life until 36 weeks postmenstrual age
