Study information

Scientific title


SGA Brain Development study

Study hypothesis

This study aims to evaluate the effect of growth hormone treatment on brain functioning and development in children born with a low birth weight/length with incomplete catch up growth.

The two other hypotheses this study aims to evaluate are:
1. Is there a difference in brain functioning in children born with a low birth weight/length between those without and with complete catch up growth?
2. Will intra-uterine growth failure affect brain development/functioning?

Ethics approval

Approval received from the Medical Ethics Review Committee of de Vrije Universiteit medical centre, Amsterdam on the 1st March 2007 (ref: 06/279).

Study design

Non-randomised parallel group trial

Trial setting


Trial type


Patient information sheet


Small for Gestational Age (SGA), brain development


Structural (only at baseline) and functional MRI’s, MEG and extensive neuropsychologic testing will be performed at baseline, after one year and three years in both groups A (treatment with growth hormone (somatropin) and B (without treatment).

SGA patients older than six years of age, with incomplete catch-up growth with the indication of GH treatment, will be followed on neuropsychologic functioning.

Hypothesis 2/ 3:
In groups C and D structural and functional MRI’s, MEG and extensive neuropsychological testing will be performed only at start of the study.

Intervention type



Not Specified

Drug names

Primary outcome measure

1. To determine the effect of prenatal growth retardation on brain functioning/development
2. To determine the effect of growth hormone treatment on brain functioning/development in children born after prenatal growth retardation
3. To assess wether there is a difference in brain development in between SGA children with and without postnatal catch up growth

Secondary outcome measures
