| Scientific title | Study Towards the Effects of Post-discharge nutrition on growth and body composition of infants born less than or equal to 32 weeks gestation and/or less than or equal to 1500 g birth weight |
| Study acronym | STEP |
| Study objectives | 1. To study the effects of post-dicharge nutrition on the growth, body composition, metabolism and neurodevelopment of premature infants 2. To study the effects of catch-up growth on the body composition, metabolism and neurodevelopment of premature infants |
| Ethics approval(s) | Ethics approval received from the local ethics committee |
| Health condition(s) or problem(s) studied | Prematurity, growth retardation (intrauterine and/or postnatal) |
| Intervention | Randomisation to post-discharge or term formula between 0 and 6 months corrected age. Breast milk group as a control group. All the formula and the breast milk with fortifier are prescribed in a volume of 175 ± 15 ml/kg/day (160 - 190 ml/kg/day). The infants are seen at the outpatient clinic at 0, 3, 6, 12 and 24 months corrected age. Anthropometry is performed and motorneurodevelopment is tested by a physiotherapist. At 0, 3 and 6 months corrected age a fasting venous blood sample is taken and urine is collected. At 0 and 6 months corrected age the body composition is established with a dual-energy x-ray absorptiometry (DEXA) scan. Parents keep weekly dairies and telephonic support is offered on a regular basis. |
