Children with end-stage renal disease (ESRD) exhibit marked disproportionate stunting, according to a new study. A low average body height, but high average sitting height index during early childhood was identified in a cohort of 389 paediatric renal transplant recipients, as compared with reference data. From preschool to adult age, patients underwent a sustained increase in standardized leg length and a decrease in standardized sitting height. Restoration of body proportions was observed in the majority of patients by adulthood.
