Abstract Seventeen children with normal variant short stature and a predicted height below −2 SDS were treated with growth hormone (GH) six times a week for a period of 5 years. Patients were randomly selected to receive three different doses of GH, group 1 (n=6) 3␣IU/m2 per day, group 2 (n=6) 4.5 IU/m2 per day and group 3 (n=5) 3 IU/m2 per day in the 1st year and 4.5␣IU/m2 per day thereafter. There was a significant increase in height after 1 and 2 years for all patients and for all subgroups. However, this increase was not dependent on GH dose. The decrease in height velocity during the 2nd year was not prevented by the increase of GH dose in group 3. The change of predicted height after 2 years was +0.75 SDS (according to Tanner Whitehouse). Fourteen children have been treated for 4␣years and 8 children for 5 years without a further change in height prediction. Nine patients have reached final height which was 2.4 cm (+0.41 SDS) above pretreatment height prediction. Final height was nearly identical to predicted height after 1 year of therapy. Conclusion An increment in height prediction was observed during the first 2 years of GH treatment and maintained thereafter. However, there was only a minor increase in final height over predicted height which does not justify the general use of GH in children with normal variant short stature.
