  1. Age at onset and long-term metabolic control affect height in type-1 diabetes mellitus.

    Article - En anglais

    Reduced height as a consequence of type-I-diabetes mellitus in childhood has been reported in many studies.

    However, it is still debated whether good metabolic control can normalize the growth rate.

    A total of 436 children (204 boys, 232 girls, mean age at diagnosis of diabetes 8.2 ± 0.2 years) were followed at our outpatient diabetes centre.

    Z-scores for height were evaluated in relation to duration of diabetes, age at onset and long-term metabolic control.

    At diagnosis, height in children with diabetes was significantly above the reference population (+0.43 ± 0.09).

    Standardized height decreased during the subsequent course of diabetes.

    This likely represents a delay of growth, as the final height (chronological age>18 years, n=144) was+0.27 ± 0.09.

    Growth reduction was more pronounced in patients diagnosed before the onset of puberty and final height in patients with a prepubertal onset of diabetes was significantly lower (+0.10 ± 0.13) compared to patients with a pubertal postpubertal onset (+0.52 ± 0.14).

    Among patients with a prepubertal onset, the subgroup with « poor'metabolic control (long-term median HbA1c>7%) lost significantly more height compared to patients with » good'metabolic control.

    Conclusion Despite modern treatment regimens, reduced longitudinal growth can still be demonstrated in type-I diabetes.

    This parameter therefore provides a valuable endpoint for quality control in paediatric diabetology.
