Evaluation of attention before and after 2 years of growth hormone treatment in intrauterine growth retarded children.

The objective of this study was to assess attention in children with short stature following intrauterine growth retardation (IUGR), at baseline and after 2 years of growth hormone (hGH) treatment. At baseline, all of the children had a birth height and a current height below the third centile. The attention measures (Sonneville Visual Attention Tasks: SVAT) of the IUGR group were compared with those of a comparison sample. In the baseline analyses, 48 children with IUGR and 119 comparison children were included; the 2-year follow-up analyses involved 41 children with IUGR and 68 comparison children. At baseline, children with IUGR showed deficits in divided, focused, and sustained attention. They were less accurate, exhibited more variability in reaction time, and performed more slowly and more impulsively than did the children in the comparison sample. After 2 years of hGH treatment, the IUGR group exhibited deficits in divided and sustained attention. They were still less accurate and showed more variability in reaction time and more impulsiveness. Current head circumference, the type of delivery, and global intelligence of children with IUGR were significantly correlated with attention measures. We hypothesize that short stature following IUGR and attention deficits are related, and that hGH treatment seems to have some beneficial effect on attentional capacity.

Self-concept before and after two years of growth hormone treatment in intrauterine growth-retarded children.

The objective of this study was to assess self-concept in children with short stature after intrauterine growth retardation (IUGR), before and after 2 years of growth hormone (hGH) treatment. We assessed 25 children before treatment, and 40 children after a 2-year treatment period. Seventeen of the 25 children of whom we had pretreatment data, were reassessed after 2 years of hGH treatment. All children had a birth length below the 3rd percentile, and did not show catch-up growth (current height < P3). We compared the self-concept measures (Self-Perception Profile for Children; SPPC) of the IUGR group with similar measures of a Dutch school sample. Four of the six SPPC mean scale scores of the IUGR group prior to treatment were significantly lower than mean scores of the school sample. Mean-scale scores of the group children, assessed after 2 years of hGH treatment, did not differ significantly from those of the school sample. In the group of 17 children who were assessed before as well as after 2 years of treatment, the mean scale scores of 'social acceptance' and 'general self-worth' were significantly higher at the second assessment (t = -5.93, p < 0.001 and t = -4.36, p < 0.001, respectively). From the present study we can hypothesize that short stature after IUGR and a low self-concept are related.
